How can I change the current file to another in Windows Media Player?

I am using Visual Studio .Net Framework to create a slideshow that operates on its own after clicking the "play" button. My current issue is that I do not know how to go about making the application go to the next file in the document after the video has ended. At the moment I have it setup for the user to select a time period for how long they want each image displayed, but I would rather have this feature automated.
This is my current code :
{
public partial class TVDisplay : Form
{
// Time f3 = new Time();
public TVDisplay()
{
//f3.Show();
InitializeComponent();
//both listview and listbox clear at initilize//
listBox1.Items.Clear();
listView1.Items.Clear();
//xml file from first application is read for department information, and that path and department are placed in textbox3 to be read by the listbox//
var xd = new XmlDocument();
string pathz = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
string filepath = pathz + #"\Assigned_Television.xml";
xd.Load(filepath);
// var list = xd.GetElementsByTagName("Television");
textBox3.Text = xd.GetElementsByTagName("Path")[0].InnerText;
}
protected override bool ProcessDialogKey(Keys keyData)
{
//when esacpe is pressed, the display screen is windowed instead of fullscreen//
if (Form.ModifierKeys == Keys.None && keyData == Keys.Escape)
{
FormBorderStyle = FormBorderStyle.Sizable;
WindowState = FormWindowState.Normal;
return true;
}
return base.ProcessDialogKey(keyData);
}

How to use check a Button in another Button statement? c#

I am having a problem . I want to use if statement to check if a button is clicked. For Example:
public void button1_Click(object sender, EventArgs e)
{
while (1)
{
...
...
...
if (Button2 == clicked)
{
break;
}
}
}
But it's not working like this, because the ".click" can only be on the left side of "+=" or "-=". Any idea how i can check if Button2 is clicked?
the code is loking like this: and i want to check button2 to stop the "programm".
the check for the Button2 is nearly at the end of the code ;)

Hm...
bool b1clicked = false, b2clicked = false;
public void button2_Click(object sender, EventArgs e)
{
b2clicked = true;
}
public void button1_Click(object sender, EventArgs e)
{
b1clicked = true;
if (b1clicked && b2clicked)
{
//...
}
}

Beside the weird behavior you want..and since you are not using Threads, you have the following options:
Local functions (.Net > 4.7)
private void B_Click(object sender, EventArgs e)
{
bool clickFlag = false;
void Click(object sender2, EventArgs e2)
{
clickFlag = true;
}
b2.Click += Click;
while (!clickFlag)
{
Thread.Sleep(1);
}
b2.Click -= Click;
//Continue with your stuff
}
Threads
Thread newThread;
private void Button1_Click()
{
newThread = new Thread(YourBreakableProcess);
newThread.Start();
}
private void Button2_Click()
{
newThread.Join();
}
private void YourBreakableProcess()
{
//Your breakable process
}
Async methods.
I hope you find a solution. Cheers.
Edit:
Since what you want is to interrupt the process of whatever you are doing, the only option you have is Local fuctions as shown above, if you are not tied to a specific framework version.
BackgroundWorker and check in every step if the button 2 was pressed with the flag thing mentioned in other answer.
Threads, and make a thread.Join when the button 2 is pressed.
Edit 2:
Updated answer with Threads, I will recommend that if you go with this option it is much better to use a BackgroundWorker instead as you will have the whole control of the process breaking it only in the place where it would be fine to break it.

You can achieve this using a flag variable. Declare and initialize flag value to false.On button2 click change flag value to true as follows,
private bool flag= false;
private void button2_Click(object sender, EventArgs e)
{
flag= true;
}
public void button1_Click(object sender, EventArgs e)
{
//Use flag to check whether button 2 has clicked or not
if (flag)
{
}
else
{
}
}

How to show the label for couple of seconds and show another label in form

I have a mini form3 https://imageshack.com/i/p1zxB6Lqp which shows a gif image running for 4 sec. So i need to show 4 different
labels in same position..
For example
label 1 - `Connecting to smtp server..`
label 2 - `Fetching recipients..`
label 3 - `Attaching necessary G-code files..`
label 4 - `Please wait sending..`
How can i show all these labels one after another in same position.. so it looking more professional
for sending mail.
My code snippet:-
Form1
private void button2_Click(object sender, EventArgs e)
{
//mail inforamtion
_f3.ShowDialog(); // - - >> is the form i wanted with all labels
smtp.Send(msg);
MessageBox.Show("Email Successfully Sent!!!", "Mail!!!.");
Environment.Exit(0);
}
Form3:
Timer formCloser = new Timer();
private void Form3_Load(object sender, EventArgs e)
{
timer1.Interval = 5000;
timer1.Enabled = true;
timer1.Tick += new EventHandler(timer1_Tick);
}
private void timer1_Tick(object sender, EventArgs e)
{
this.DialogResult = DialogResult.OK;
timer1.Stop();
}
Please help me out.. how can i add label in my form..

Found the answer.. I kept two timers for each function,
timer1 to run the mini form only for 5 seconds.
and timer two to run only for 1 sec. If any body has a better code to share with please..
Most welcome!!
Here is my code:
private void Form3_Load(object sender, EventArgs e)
{
timer1.Interval = 5000;
timer1.Enabled = true;
timer1.Tick += new EventHandler(timer1_Tick);
timer2.Interval = 1000;
timer2.Start();
}
private void timer1_Tick(object sender, EventArgs e)
{
this.DialogResult = DialogResult.OK;
timer1.Stop();
}
int StopTime = 0;
private void timer2_Tick(object sender, EventArgs e)
{
StopTime++;
if (StopTime == 1)
{
label1.Text = " Connecting to smtp server..";
}
if (StopTime == 2)
{
label1.Text = " Fetching recipients..";
}
if (StopTime == 3)
{
label1.Text = " Attaching G-code files..";
}
if (StopTime == 4)
{
label1.Text = " Done!!";
StopTime = 0;
timer2.Stop();
}
}

after clicking on button1 should be switched on and off checkBox the time interval

Can you help? In C#, after clicking on button1, checkBoxWMVFile (the time interval)
should be switched on and off.
private void button1_Click(object sender, EventArgs e)
{
if (timercheckbox.Enabled == true)
{
timercheckbox = new Timer();
timercheckbox.Start();
timercheckbox.Interval = 10000; // 10 second
if(timercheckbox.Enabled)
{
timercheckbox.Start();
checkBoxWMVFile.Checked = true;
}
else
{
timercheckbox.Stop();
checkBoxWMVFile.Checked = false;
}
}
}

As I understood, you need something like this
private Timer _timer = new Timer();
public Form1()
{
InitializeComponent();
_timer.Interval = 10000;
_timer.Tick += new EventHandler(_timer_Tick);
}
private void button1_Click(object sender, EventArgs e)
{
if (checkBox1.Checked)
{
checkBox1.Checked = false;
if(_timer.Enabled)
_timer.Stop();
}
else
{
checkBox1.Checked = true;
if (!_timer.Enabled)
_timer.Start();
}
}
void _timer_Tick(object sender, EventArgs e)
{
//do something here
throw new NotImplementedException();
}

In order for your code to work, you have to reverse the logic i.e.
private void button1_Click(object sender, EventArgs e)
{
if(checkBoxWMVFile.Checked == false)//if the textbox is not checked
{
if (timercheckbox == null)//If this is the first time
{
timercheckbox = new Timer();//Create a timer
timercheckbox.Interval = 10000; // Set the interval, before starting it.
timercheckbox.Start();//Start it
}
else timercheckbox.Start();//If it is not the first time, just start it
checkBoxWMVFile.Checked = true;//Check the checkbox
}
else//the checkbox is checked
{
timercheckbox.Stop();//Stop the timer
checkBoxWMVFile.Checked = false;//Uncheck the checkbox
}
}

This code works correctly:
// InitializeComponent
this.timercheckbox.Interval = 5000;
this.timercheckbox.Tick += new System.EventHandler(this.timercheckbox_Tick);
private void timercheckbox_Tick(object sender, EventArgs e)
{
checkBoxWMVFile.Checked = false;
checkBoxWMVFile.Checked = true;
}
private void button1_Click(object sender, EventArgs e)
{
if( timercheckbox.Enabled == true )
{
timercheckbox.Enabled = false;
button1.Text = "Start Auto save";
}
else
{
timercheckbox.Interval = (int)numericChnageTime.Value;
timercheckbox.Enabled = true;
checkBoxWMVFile.Checked = true;
button1.Text = "Stop Auto save";
}
}

Countdown after clicking a button that goes from 10 to 0 setting text on a label C#

My problem is very simple but I can't figure it out, so I need your help.
The problem is that I have a button and a label in a form, I simply want to click the button and see the label countdown from 10 to 0 and after that happens the form closes, that simple, can someone help me with this?
BTW, my real app is a form that shows video in real time from my webcam and the idea is to click the button, see the count down and when it finishes the appp saves the current frame as an image.
Thanks in advice!

It sounds like you probably just need three things:
A counter in your class as an instance variable
A timer (System.Windows.Forms.Timer or a DispatcherTimer depending on what UI framework you're using)
A method handling the timer's Tick even which decrements the counter, updates the UI, and stops the timer + takes a snapshot if the counter reaches 0
You can do all of this without any other threads.

Using WindowsFormsApplication u can do it like this:
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
timer1.Enabled = false; // Wait for start
timer1.Interval = 1000; // Second
i = 10; // Set CountDown Maximum
label1.Text = "CountDown: " + i; // Show
button1.Text = "Start";
}
public int i;
private void button1_Click(object sender, EventArgs e)
{
// Switch Timer On/Off
if (timer1.Enabled == true)
{ timer1.Enabled = false; button1.Text = "Start"; }
else if (timer1.Enabled == false)
{ timer1.Enabled = true; button1.Text = "Stop"; }
}
private void timer1_Tick(object sender, EventArgs e)
{
if (i > 0)
{
i = i - 1;
label1.Text = "CountDown: " + i;
}
else
{ timer1.Enabled = false; button1.Text = "Start"; }
}
}
You only need a label, a button and a timer.

use this code. put one timer,label and button.
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
timer1.Tick += new EventHandler(timer1_Tick);
}
private static int i = 10;
private void button1_Click(object sender, EventArgs e)
{
label1.Text = "10";
timer1.Interval = 1000;
timer1.Start();
}
private void timer1_Tick(object sender, EventArgs e)
{
label1.Text = (i--).ToString();
if (i < 0)
{
timer1.Stop();
}
}
}
