I need to show splash screen on my application start for few seconds. Does anybody know how to implement this?
Will be much appreciate for the help.
First, create your splash screen as a borderless, immovable form with your image on it, set to initially display at the center of the screen, colored the way you want. All of this can be set from within the designer; specifically, you want to:
Set the form's ControlBox, MaximizeBox, MinimizeBox and ShowIcon properties to "False"
Set the StartPosition property to "CenterScreen"
Set the FormBorderStyle property to "None"
Set the form's MinimumSize and MaximumSize to be the same as its initial Size.
Then, you need to decide where to show it and where to dismiss it. These two tasks need to occur on opposite sides of the main startup logic of your program. This could be in your application's main() routine, or possibly in your main application form's Load handler; wherever you're creating large expensive objects, reading settings from the hard drive, and generally taking a long time to do stuff behind the scenes before the main application screen displays.
Then, all you have to do is create an instance of your form, Show() it, and keep a reference to it while you do your startup initialization. Once your main form has loaded, Close() it.
If your splash screen will have an animated image on it, the window will need to be "double-buffered" as well, and you will need to be absolutely sure that all initialization logic happens outside the GUI thread (meaning you cannot have your main loading logic in the mainform's Load handler; you'll have to create a BackgroundWorker or some other threaded routine.
Here are some guideline steps...
Create a borderless form (this will be your splash screen)
On application start, start a timer (with a few seconds interval)
Show your Splash Form
On Timer.Tick event, stop timer and close Splash form - then show your main application form
Give this a go and if you get stuck then come back and ask more specific questions relating to your problems
simple and easy solution to create splash screen
open new form use name "SPLASH"
change background image whatever you want
select progress bar
select timer
now set timer tick in timer:
private void timer1_Tick(object sender, EventArgs e)
{
progressBar1.Increment(1);
if (progressBar1.Value == 100) timer1.Stop();
}
add new form use name "FORM-1"and use following command in FORM 1.
note: Splash form works before opening your form1
add this library
using System.Threading;
create function
public void splash()
{
Application.Run(new splash());
}
use following command in initialization like below.
public partial class login : Form
{
public login()
{
Thread t = new Thread(new ThreadStart(splash));
t.Start();
Thread.Sleep(15625);
InitializeComponent();
enter code here
t.Abort();
}
}
http://solutions.musanitech.com/c-create-splash-screen/
I wanted a splash screen that would display until the main program form was ready to be displayed, so timers etc were no use to me. I also wanted to keep it as simple as possible.
My application starts with (abbreviated):
static void Main()
{
Splash frmSplash = new Splash();
frmSplash.Show();
Application.Run(new ReportExplorer(frmSplash));
}
Then, ReportExplorer has the following:
public ReportExplorer(Splash frmSplash)
{
this.frmSplash = frmSplash;
InitializeComponent();
}
Finally, after all the initialisation is complete:
if (frmSplash != null)
{
frmSplash.Close();
frmSplash = null;
}
Maybe I'm missing something, but this seems a lot easier than mucking about with threads and timers.
create splash
private void timer1_Tick(object sender, EventArgs e)
{
counter++;
progressBar1.Value = counter *5;
// label2.Text = (5*counter).ToString();
if (counter ==20)
{
timer1.Stop();
this.Close();
}
}
this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
this.BackColor = System.Drawing.SystemColors.GradientInactiveCaption;
this.ClientSize = new System.Drawing.Size(397, 283);
this.ControlBox = false;
this.Controls.Add(this.label2);
this.Controls.Add(this.progressBar1);
this.Controls.Add(this.label1);
this.ForeColor = System.Drawing.SystemColors.ControlLightLight;
this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
this.Name = "Splash";
this.ShowIcon = false;
this.ShowInTaskbar = false;
this.StartPosition = System.Windows.Forms.FormStartPosition.CenterScreen;
this.ResumeLayout(false);
this.PerformLayout();
Then in your application
sp = new Splash();
sp.ShowDialog();
The other answers here cover this well, but it is worth knowing that there is built in functionality for splash screens in Visual Studio: If you open the project properties for the windows form app and look at the Application tab, there is a "Splash screen:" option at the bottom. You simply pick which form in your app you want to display as the splash screen and it will take care of showing it when the app starts and hiding it once your main form is displayed.
You still need to set up your form as described above (with the correct borders, positioning, sizing etc.)
None of the other answers gave me exactly what I was looking for. Read on for my solution to the problem.
I want a splash screen to fade in from 0% opacity to 100% opacity while things boot up, with a minimum display time of 2000ms (to allow the full fade in effect to show). Once everything is ready, I want the splash screen to display for a further 500ms while the main screen displays behind the splash screen. Then I want the splash screen to go away, leaving the main screen running.
Note that I use the MVP pattern for winforms. If you don't use MVP, you will need to simplify the below example a little.
Long story short, you need to create an AppContext class that inherits from ApplicationContext. I have put this in my Program.cs as below:
static class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
Application.SetHighDpiMode(HighDpiMode.SystemAware);
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new AppContext());
}
}
public class AppContext : ApplicationContext
{
private IMainPresenter _mainPresenter;
private bool _ready;
public AppContext()
{
_ready = false;
using (ISplashPresenter splashPresenter = new SplashPresenter(new SplashView()))
{
Stopwatch sw = Stopwatch.StartNew();
_mainPresenter = new MainPresenter(new MainView());
_mainPresenter.Closed += MainPresenter_Closed;
new Thread(() =>
{
// !!! Do work here !!!
if (sw.ElapsedMilliseconds < 2000)
Thread.Sleep(2000 - (int)sw.ElapsedMilliseconds);
_ready = true;
})
.Start();
while (!_ready)
{
Application.DoEvents();
Thread.Sleep(1);
}
_mainPresenter.Show();
_ready = false;
new Thread(() =>
{
Thread.Sleep(500);
_ready = true;
})
.Start();
while (!_ready)
{
Application.DoEvents();
Thread.Sleep(1);
}
}
}
private void MainPresenter_Closed(object sender, EventArgs e)
{
ExitThread();
}
}
There are several implementation specific details that I haven't gone into here, such as ISplashPresenter implementing IDisposable and exactly how the fade in is managed; if enough people request it I will edit this answer to include a complete example.
First you should create a form with or without Border (border-less is preferred for these things)
public class SplashForm : Form
{
Form _Parent;
BackgroundWorker worker;
public SplashForm(Form parent)
{
InitializeComponent();
BackgroundWorker worker = new BackgroundWorker();
this.worker.DoWork += new System.ComponentModel.DoWorkEventHandler(this.worker _DoWork);
backgroundWorker1.RunWorkerAsync();
_Parent = parent;
}
private void worker _DoWork(object sender, DoWorkEventArgs e)
{
Thread.sleep(500);
this.hide();
_Parent.show();
}
}
At Main you should use that
static class Program
{
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new SplashForm());
}
}
Maybe a bit late to answer but i would like to share my way.
I found an easy way with threads in the main program for a winform application.
Lets say you have your form "splashscreen" with an animation, and your "main" which has all your application code.
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Thread mythread;
mythread = new Thread(new ThreadStart(ThreadLoop));
mythread.Start();
Application.Run(new MainForm(mythread));
}
public static void ThreadLoop()
{
Application.Run(new SplashScreenForm());
}
In your main form in the constructor:
public MainForm(Thread splashscreenthread)
{
InitializeComponent();
//add your constructor code
splashscreenthread.Abort();
}
This way the splashscreen will last just the time for your main form to load.
Your splashcreen form should have his own way to animate/display information.
In my project my splashscreen start a new thread, and every x milliseconds it changes his main picture to another which is a slightly different gear, giving the illusion of a rotation.
example of my splashscreen:
int status = 0;
private bool IsRunning = false;
public Form1()
{
InitializeComponent();
StartAnimation();
}
public void StartAnimation()
{
backgroundWorker1.WorkerReportsProgress = false;
backgroundWorker1.WorkerSupportsCancellation = true;
IsRunning = true;
backgroundWorker1.RunWorkerAsync();
}
public void StopAnimation()
{
backgroundWorker1.CancelAsync();
}
delegate void UpdatingThreadAnimation();
public void UpdateAnimationFromThread()
{
try
{
if (label1.InvokeRequired == false)
{
UpdateAnimation();
}
else
{
UpdatingThreadAnimation d = new UpdatingThreadAnimation(UpdateAnimationFromThread);
this.Invoke(d, new object[] { });
}
}
catch(Exception e)
{
}
}
private void UpdateAnimation()
{
if(status ==0)
{
// mypicture.image = image1
}else if(status ==1)
{
// mypicture.image = image2
}
//doing as much as needed
status++;
if(status>1) //change here if you have more image, the idea is to set a cycle of images
{
status = 0;
}
this.Refresh();
}
private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
BackgroundWorker worker = sender as BackgroundWorker;
while (IsRunning == true)
{
System.Threading.Thread.Sleep(100);
UpdateAnimationFromThread();
}
}
Hope this will help some people.
Sorry if i have made some mistakes. English is not my first language.
Here is the easiest way of creating a splash screen:
First of all, add the following line of code before the namespace in Form1.cs code:
using System.Threading;
Now, follow the following steps:
Add a new form in you application
Name this new form as FormSplashScreen
In the BackgroundImage property, choose an image from one of your folders
Add a progressBar
In the Dock property, set it as Bottom
In MarksAnimationSpeed property, set as 50
In your main form, named as Form1.cs by default, create the following method:
private void StartSplashScreen()
{
Application.Run(new Forms.FormSplashScreen());
}
In the constructor method of Form1.cs, add the following code:
public Form1()
{
Thread t = new Thread(new ThreadStart(StartSplashScreen));
t.Start();
Thread.Sleep(5000);
InitializeComponent();//This code is automatically generated by Visual Studio
t.Abort();
}
Now, just run the application, it is going to work perfectly.
Here's my 2023 take on a 2011 question.
Over time, I've done this many times in many ways. The approach that currently use:
Force the main form Handle creation so that the message that creates the splash can be posted into the main form's message queue using BeginInvoke. This allows the main form ctor to return. Ordinarily the handle (the native hWnd) doesn't come into existence until it's shown. Therefore, it needs to be coerced while it's still hidden.
Override the SetVisibleCore() preventing the main window from becoming visible until the Splash has finished processing.
public partial class MainForm : Form
{
public MainForm()
{
InitializeComponent();
Debug.Assert(!IsHandleCreated, "Expecting handle is not yet created.");
// Ordinarily we don't get the handle until
// window is shown. But we want it now.
_ = Handle;
Debug.Assert(IsHandleCreated, "Expecting handle exists.");
// Call BeginInvoke on the new handle so as not to block the CTor.
BeginInvoke(new Action(()=> execSplashFlow()));
}
protected override void SetVisibleCore(bool value) =>
base.SetVisibleCore(value && _initialized);
bool _initialized = false;
private void execSplashFlow()
{
using (var splash = new SplashForm())
{
splash.ShowDialog();
}
_initialized= true;
WindowState = FormWindowState.Maximized;
Show();
}
}
Splash Example
The async initialization can be performed in the Splash class itself or it can fire events causing the main app to do things. Either way, when it closes itself the main form will set the _initialized bool to true and it is now capable of becoming visible.
public partial class SplashForm : Form
{
public SplashForm()
{
InitializeComponent();
StartPosition = FormStartPosition.CenterScreen;
FormBorderStyle = FormBorderStyle.None;
}
protected async override void OnVisibleChanged(EventArgs e)
{
base.OnVisibleChanged(e);
if (Visible)
{
labelProgress.Text = "Updating installation...";
progressBar.Value = 5;
await Task.Delay(1000);
progressBar.Value = 25;
// SIMULATED background task like making an API call or loading a
// database (long-running task that doesn't require the UI thread).
labelProgress.Text = "Loading avatars...";
await Task.Delay(1000);
labelProgress.Text = "Fetching game history...";
progressBar.Value = 50;
await Task.Delay(1000);
labelProgress.Text = "Initializing scenario...";
progressBar.Value = 75;
await Task.Delay(1000);
labelProgress.Text = "Success!";
progressBar.Value = 100;
await Task.Delay(1000);
DialogResult= DialogResult.OK;
}
}
}
Try this code
public partial class ssplashscreen : Form
{
public ssplashscreen()
{
InitializeComponent();
}
private void timer1_Tick(object sender, EventArgs e)
{
progressBar1.Increment(1);
if (progressBar1.Value == 100)
{
timer1.Stop();
this.Hide();
Form frm = new login();
frm.Show();
}
}
}
Try This:
namespace SplashScreen
{
public partial class frmSplashScreen : Form
{
public frmSplashScreen()
{
InitializeComponent();
}
public int LeftTime { get; set; }
private void frmSplashScreen_Load(object sender, EventArgs e)
{
LeftTime = 20;
timer1.Start();
}
private void timer1_Tick(object sender, EventArgs e)
{
if (LeftTime > 0)
{
LeftTime--;
}
else
{
timer1.Stop();
new frmHomeScreen().Show();
this.Hide();
}
}
}
}
I am working with Windows forms. I have set up a splash screen to appear when opening the program like this.
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
this.FormBorderStyle = FormBorderStyle.None;
}
private void timer1_Tick(object sender, EventArgs e)
{
progressBar1.Increment(15);
if (progressBar1.Value == 30) timer1.Stop();
}
It has a progress bar and a timer. I got the idea from another post here. This is working OK, the splash screen is appearing as it should. On the windows form to appear after this I have:
Thread t = new Thread(new ThreadStart(splash));
t.Start();
Thread.Sleep(2000);
InitializeComponent();
t.Abort();
The problem is as follows. When I open the exe, the splash screens appear for about 2 secs as it should, and then when it goes away, the next form appears a second and then goes behind every other window I have opened.
Do you know how can I fix it?
Update 1:
public void splash()
{
System.Windows.Forms.Application.Run(new Form2());
}
This is my splash screen
Final Update:
I got it to work this way.
Splash splash = new Splash();
Instalador instalador = new Instalador();
splash.Show();
Thread.Sleep(2 * 1000);
splash.Close();
Application.Run(instalador);
This on the main. I do not know how OK is this, but it works.
To answer your specific question, you might get away with just adding this.Activate() after InitializeComponent
Thread t = new Thread(new ThreadStart(splash));
t.Start();
Thread.Sleep(2000);
InitializeComponent();
this.Activate();
t.Abort();
However, at the very least, implement handshaking that shuts down the splash screen nicely rather than just aborting the thread.
Also, depending on exactly what you're doing in your splash screen thread, there may be a multitude of subtle issues - e.g. the Z-ordering issue you're currently having.
Typically, I launch my splash screens from Main() before Application.Run({main form}) and also call Application.Run({splashScreen}) from it's thread handler. Application.Run has thread affinity so the splash screen will get its own ApplicationContext which will properly hook Closing/Closed events to shutdown the thread and raise ThreadExit just by invoking or beginInvoking SplashScreen.Close() (typically from MainForm_Shown event handler). It also has other minor benefits such as Application.OpenForms containing the splash screen.
Taking this route has pretty much eliminated my bugs and frustrations with splash screens.
-Begin Edit-
A more thorough example:
Start up the second thread and ApplicationContext in Main()
static class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Thread t = new Thread(new ThreadStart(splash));
t.IsBackground = true;
t.SetApartmentState(ApartmentState.STA);
t.Start();
Application.Run(new Form1());
}
private static void splash()
{
Application.Run(new Form2());
}
}
Splash screen with a SetProgress method added so you can update it externally if you wish.
public partial class Form2 : Form
{
public Form2()
{
InitializeComponent();
timer1.Start();
}
public void SetProgress()
{
if (this.InvokeRequired) //Should have been handled by SplashScreenHandler but check just in case.
this.BeginInvoke(new Action(SetProgress));
progressBar1.Increment(15);
}
private void timer1_Tick(object sender, EventArgs e)
{
progressBar1.Increment(15);
if (progressBar1.Value == 30) timer1.Stop();
}
}
Main form: Notice nothing in constructor and the Shown event handler shuts down the splash screen(s) without having to carry in a reference (if you're going to instead rely on the timer for status updates.)
public partial class Form1 : Form
{
public Form1()
{
//Simulate a long init
Thread.Sleep(2000);
InitializeComponent();
}
private void Form1_Shown(object sender, EventArgs e)
{
foreach (var splashScreen in Application.OpenForms.OfType<Form2>())
{
splashScreen.BeginInvoke( (Action) delegate () { splashScreen.Close(); });
}
}
}
-End Edit-
After long time struggle i got the solution.
Use the code into Login Form (Form_Load) this.Activate();
Example:
private void login_Load(object sender, EventArgs e)
{
this.Activate();
}
I had the same issue and after stuggling for a very long time I ended up doing the following in the Load event of the main form after closing the splash screen:
//Manually activate frmMain as it gets back in the Z-order by Windows when splash screen closes.
NativeMethods.SetForegroundWindow(this.Handle);
this.Activate();
Where "SetForegroundWindow" is defined as follows:
/// <summary>
/// Sets foreground window
/// </summary>
/// <param name="hWnd"></param>
/// <returns></returns>
[DllImport("user32.dll")]
internal static extern bool SetForegroundWindow(IntPtr hWnd);
That being said we probably need to see more of your code.
why The process still on Windows Task list manager after close programme ?
i use login Form.cs
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Login());
}
after the user succesuly login, i redirect to another Masterpage
this.Hide();
Main_Usr oMainUsr = new Main_Usr();
oMainUsr.Visible = true;
my pseudo master page like this:
public Main_Usr()
{
InitializeComponent();
this.IsMdiContainer = true;
}
when i close the masterpage, The process still on Windows Task list manager.
But when i close the login page, it kill the process on Windows Task list manager.
is that mean because i just hide le login page ?
must i close all window to realy quit/kill the process ?
Thanks you in advance,
Stev
In winforms process will be killed, when main application form is closed. Main application form is one specified in Application.Run call. In your case it is Login form:
Application.Run(new Login());
To close form you should call Close method. When you call Hide or set Visibility to false, form stays in memory. It just becomes hidden from user.
So, to achieve desired functionality you should change main application form to Main_Usr:
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Main_Usr()); // change main form
}
Then subscribe to Load event of Main_User form. And in the event handler do following:
private void Main_User_Load(object sender, EventArgs e)
{
using (var loginForm = new Login())
{
Hide(); // hide main form
if (loginForm.ShowDialog() != System.Windows.Forms.DialogResult.OK)
{
Close(); // close main form and kill process
return;
}
Show(); // show main form if user logged in successfully
}
}
UPDATE: You can do this all in Main method, like this way
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
using(var loginForm = new Login())
if (loginForm.ShowDialog() != System.Windows.Forms.DialogResult.OK)
return;
Application.Run(new Main_Usr()); // change main form
}
but usually I don't hide main form and show it below login form. So, in this case you should use Load event handler. It's up to you.
BTW there is no masterpages and pages in winforms. This all is for ASP.NET. Here you have forms :)
Also consider naming like LoginForm, MainForm etc.
This is because the application message loop is associated with your Login form (Application.Run(new Login()) does this), so you need to close the form which started the application to end the process.
Alternatively, you could just call LoginForm.Show(), before Application.Run, store credentials somewhere and then call Application.Run(new Main_Usr)
Because Login is the last form of the application to close, you load Main_User only after that - even if Login is hidden it's still actually there. Windows Forms applications are by default configured to exit when the last form closes.
this.Hide()
doesn`t kill the window.
So it remains hidden and process remains in memory.
this.Close() closes the window and removes its object from memory.
It is better to do something like this:
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
var l = new Login();
l.ShowDialog();
if(l.Passed)
Application.Run(new Login());
}
And implement Passed property inside login window.
By the way, do you have any multithreading inside?
It is another source of errors of this type.
i found it, i just use the dizlog.
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Login oLogin = new Login();
oLogin.ShowDialog();
Application.Run(new Main_Usr());
}
i follow code the #lazyberezovsky and add this on my Login.cs
private void simpleButton_Valider_Click(object sender, EventArgs e)
{
.....
DialogResult = DialogResult.OK;
return;
.....
}
I would like to know the appropriate way to completely terminate a Forms application. I open the form in the standard way using the code:
namespace History
{
static class Program
{
[STAThread]
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new DisplayHistory());
}
}
}
...and here is a barebones version of the DisplayHistory function with the various things I've tried to terminate the application commented out. The first two cause an unhandled exception stating that I cannot access a disposed object. The third one has no effect at all, and the fourth one won't compile at all because I get an error saying that "Application does not contain a definition for Current":
public DisplayHistory()
{
InitializeComponent();
// this.Close();
// Close();
// Application.Exit();
// Application.Current.Shutdown();
}
Instead of trying to close it in constructor, it's better not to open the form.
But if you really want to close the form in constructor based on some condition, you can subscribe for Load event before InitializeComponent in code and close the form using this.Close()
:
public Form1()
{
if (some criteria)
{
this.Load += (sender, e) => { this.Close(); };
}
return;
InitializeComponent();
}
To close an application normally, you can call below codes anywhere except constructor of form:
this.Close();
Application.Exit();
To force the application to stop, or close it abnormally, you can call Environment.Exit anywhere including the form constructor:
Environment.Exit(1);
Can you tell me how can I close a first application and immediately run a second application?
First Step: (Login validation)
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Login());
}
Second Step: (Run main program)
If the user succesfully logins to program, I need to close the login application and run the new application named "Main".
The check for the login is the following:
if (access.access == true)
{
Application.Run(new Main());
Close();
}
else
MessageBox.Show("Přihlašovací jméno nebo heslo neni správné");
Debug Error:
Create a second message loop on a single thread is an invalid operation. Instead, use the Application.RunDialog or form.ShowDialog.
I think that the best answer for my problem is to use ShowDialog and DialogResult, but I don't know how can I use them for my settings.
You could run a modal dialog asking for credentials before entering the main loop
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
bool validated = false;
using(frmLogin fLogin = new frmLogin())
{
if(fLogin.ShowDialog() == DialogResult.OK)
validated = true;
}
if(validated)
Application.Run(new Main());
else
MessageBox.Show("Bye");
}
Have a look at Creating a Windows Forms Application With Login
Here the difference is that the Main still runs frmMain
static void Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new frmMain());
}
The main form handles the frmLogin
public partial class frmMain : Form
{
frmLogin _login = new frmLogin();
public frmMain()
{
InitializeComponent();
_login.ShowDialog();
if (_login.Authenticated)
{
MessageBox.Show("You have logged in successfully " + _login.Username);
}
else
{
MessageBox.Show("You failed to login or register - bye bye","Error",MessageBoxButtons.OK,MessageBoxIcon.Error);
Application.Exit();
}
}
}
