I am using "●" as the password character for my login form. I have a check box there titled "Show Password". If a person clicks on "show password" the "●" should be removed and the password should be shown as actual text. I am not able to do that; here is the code:
private void LoginForm_Load(object sender, EventArgs e)
{
Passtxt.PasswordChar = '●';
if (checkBox_Showpass.Checked == true)
{
Passtxt.PasswordChar = '\0';
}
}
Ok, finally got that to work: Copied the if statement and pasted that into checkBox_Showpass_CheckedChanged method:
private void checkBox_Showpass_CheckedChanged(object sender, EventArgs e)
{
if (checkBox_Showpass.Checked == true)
{
this.Passtxt.PasswordChar = '\0';
}
}
Use UseSystemPasswordChar property to enable or disable password mode:
private void checkBox_Showpass_CheckedChanged(object sender, EventArgs e)
{
if (checkBox_Showpass.Checked == true)
Passtxt.UseSystemPasswordChar = false;
else
Passtxt.UseSystemPasswordChar = true;
}

I have a textbox in my WinForm and when I type the password in, its hidden because:
private void textBoxPWMain2_TextChanged(object sender, EventArgs e)
{
textBoxPWMain2.UseSystemPasswordChar = true;
}
is it possible to add here a button, and while the button is pressed, the password show normal and when I stop pressing the button, the password will hide again?
Maybe this? (Don't forget to subscribe to these events)
private void button2_MouseDown(object sender, EventArgs e)
{
textBoxPWMain2.UseSystemPasswordChar = false;
}
private void button2_MouseUp(object sender, EventArgs e)
{
textBoxPWMain2.UseSystemPasswordChar = true;
}
I have a solution now, I wanted something like a eye button, when you press it down the password shows, when you stop pressing, the password hides again.
Solution
First I added a pictureBox with Eye Icon and added this pictureBox to my password textbox and set Passwort textbox to .UseSystemPasswordChar
public Form1
{
textBoxPW.Controls.Add(pictureBoxEye);
pictureBoxEye.Location = new Point(95,0);
pictureBoxEye.BackColor = Color.Transparent;
textBoxPW.UseSystemPasswordChar = true;
//Subscribe to Event
pictureBoxPW.MouseDown += new MouseEventHandler(pictureBoxPW_MouseDown);
pictureBoxPW.MouseUp += new MouseEventHandler(pictureBoxPW_MouseUp);
}
Added the Mouse_Down/Up Event
private void pictureBoxEye_MouseDown(object sender, MouseEventArgs e)
{
textBoxPW.UseSystemPasswordChar = false;
}
private void pictureBoxEye_MouseUp(object sender, MouseEventArgs e)
{
textBoxPW.UseSystemPasswordChar = true;
}
This works fine for me! Thank you guys !!
Adding a bit change details to ispiro's answer
public void button1_MouseDown(object sender, EventArgs e)
{
textBox1.PasswordChar = '\0';
textBox1.UseSystemPasswordChar = false;
}
public void button1_MouseUp(object sender, EventArgs e)
{
textBox1.PasswordChar = '*';
textBox1.UseSystemPasswordChar = true;
}
Before:-
After :-
Is there a reason you set the UseSystemPasswordChar in the TextChanged event?
If you can set the property in the Initialize() method or in the constructor you can implement the following events for your button:
private void button1_MouseDown(object sender, MouseEventArgs e)
{
textBoxPWMain2.UseSystemPasswordChar = false;
}
private void button1_MouseUp(object sender, MouseEventArgs e)
{
textBoxPWMain2.UseSystemPasswordChar = true;
}
I have code like this:
private void button1_Click(object sender, EventArgs e)
{
openFileDialog1.ShowDialog();
}
private void openFileDialog1_FileOk(object sender, CancelEventArgs e)
{
string ext = Path.GetExtension(openFileDialog1.FileName);
if(string.Compare(ext, ".FDB") == 0)
{
string fileName = openFileDialog1.SafeFileName;
string fileDirectory = Path.GetDirectoryName(openFileDialog1.FileName);
string databaseTxt = #"C:\Users\arist\AppData\Roaming\TDWork\";
string[] database = { fileDirectory + fileName };
if (Directory.Exists(databaseTxt))
{
System.IO.File.WriteAllLines(databaseTxt + "databases.txt", database);
}
else
{
DirectoryInfo di = Directory.CreateDirectory(databaseTxt);
System.IO.File.WriteAllLines(databaseTxt + "databases.txt", database);
}
}
else
{
MessageBox.Show("Fajl koji ste izabrali nije Firebird baza (.FDB)");
e.Cancel = true;
}
}
Now, i want to create more buttons that open same file dialog. Problem is that i want to pass openFileDialog directory to different textboxes. So logic is this:
If i open with button1, pass value to textbox1,
If i open with button2, pass value to textbox2,
if i open with button3, pass value to textbox3.
So i wanted to create int check (1, 2, 3) so when i press button1, it pass check = 1 to OpenDialog1_FileOk, so i just do switch there and do actions.
Problem is i do not know how to pass it to handler, and if that is possible. Also if there is any other solution, please write it.
First, you could use your openfiledialog just like this, without handling a whole new function for it:
if(openFileDialog1.ShowDialog() == DialogResult.OK){
//...code
}
Second, for your goal you'll have to be sure that the names of your controls are exactly ending on the digit you want (e.g. "button1" and "textbox1"). Then you can do it like this:
void Button1Click(object sender, EventArgs e)
{
//MessageBox.Show(bt.Name[bt.Name.Length - 1].ToString());
if(openFileDialog1.ShowDialog() == DialogResult.OK)
{
if(!Path.GetExtension(openFileDialog1.FileName).EndsWith(".FDB")) //checking if the extension is .FDB (as you've shown in your example)
{
MessageBox.Show("Fajl koji ste izabrali nije Firebird baza (.FDB)");
return; //return if it's not and no further code gets executed
}
string fileDirectory = Path.GetDirectoryName(openFileDialog1.FileName); //getting the directory
string nameOfMyButton = (sender as Button).Name; //you get the name of your button
int lastDigitOfMyName = Convert.ToInt16(Name[Name.Length - 1]); //returns the number of your button
TextBox neededTextboxToShowDirectory = this.Controls.Find("textbox" + lastDigitOfMyName, true).FirstOrDefault() as TextBox; //this will search for a control with the name "textbox1"
neededTextboxToShowDirectory.Text = fileDirectory; //you display the text
//... doing the rest of your stuff here
}
}
You could use a private field where you save temporarily the text of your TextBox and deploy it in the click event like this:
private int whichButton = 0;
private void button1_Click(object sender, EventArgs e)
{
whichButton = 1;
openFileDialog1.ShowDialog();
}
private void button2_Click(object sender, EventArgs e)
{
whichButton = 2;
openFileDialog1.ShowDialog();
}
private void button3_Click(object sender, EventArgs e)
{
whichButton = 3;
openFileDialog1.ShowDialog();
}
use then the whichButton to choose
private void openFileDialog1_FileOk(object sender, CancelEventArgs e)
{
switch (whichButton)
{
....
}
}
I pasted the most important parts of my code below.
As you can see I'd like to work with multiple Forms. But this is how my Form behaves:
It opens Selector, when I press the second button it find the .ini file and opens ExplorerForm, but Selector IS STILL OPEN. Ofcourse I don't want that. I can't click the Selector, I just hear an error sound and the Explorer Window blinks. When I close the Explorer, both, the Explorer AND the Selector close.
But NOW the Path form opens...
When I press one of the other buttons in the Selector, it doesn't find the .INI file (that's right) and opens the Path form (and closes it in the right way).
I already used search and even implemented one of the answers there:
How I can close a 1st form without closing the full application?
My Program.cs:
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Selector());
Selector.cs:
private void button1_Click(object sender, EventArgs e)
{
Path pathForm = new Path(0);
this.Hide();
pathForm.ShowDialog();
this.Close();
}
private void button2_Click(object sender, EventArgs e)
{
Path pathForm = new Path(1);
this.Hide();
pathForm.ShowDialog();
this.Close();
}
private void button3_Click(object sender, EventArgs e)
{
Path pathForm = new Path(2);
this.Hide();
pathForm.ShowDialog();
this.Close();
}
Path.cs:
public Path(int currGame)
{
intGame = currGame;
if(MyIni.KeyExists("Path"+intGame))
{
var GamePath = MyIni.Read("Path"+intGame);
if(Directory.Exists(GamePath))
{
if (Directory.GetFiles(
GamePath, gameEXE(intGame), SearchOption.TopDirectoryOnly).Count() > 0)
{
InitializeComponent();
Explorer explorerForm = new Explorer();
this.Hide();
explorerForm.ShowDialog();
this.Hide();
}
}
}
InitializeComponent();
label1.Text = label1.Text + " " + gameString(currGame) + "!";
RegistryKey rk = Registry.LocalMachine;
RegistryKey sk1 = rk.OpenSubKey(
#"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Steam App 12100");
// III Steam
RegistryKey sk2 = rk.OpenSubKey(
#"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Steam App 12110");
// Vice City Steam
RegistryKey sk3 = rk.OpenSubKey(
#"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Steam App 12120");
// San Andreas Steam
if(intGame == 0)
{
if (sk1 != null)
{
if (sk1.GetValueNames().Contains("InstallLocation")
&& sk1.GetValue("InstallLocation").ToString() != "")
{
textBox1.Text = sk1.GetValue("InstallLocation").ToString();
}
}
}
else if(intGame == 1)
{
if(sk2 != null)
{
if(sk2.GetValueNames().Contains("InstallLocation")
&& sk2.GetValue("InstallLocation").ToString() != "")
{
textBox1.Text = sk2.GetValue("InstallLocation").ToString();
}
}
}
else if (intGame == 2)
{
if (sk3 != null)
{
if (sk3.GetValueNames().Contains("InstallLocation")
&& sk3.GetValue("InstallLocation").ToString() != "")
{
textBox1.Text = sk3.GetValue("InstallLocation").ToString();
}
}
}
}
Try modify involved code of your Selector.cs in this way:
private void button1_Click(object sender, EventArgs e)
{
this.StartPathForm(1);
}
private void button2_Click(object sender, EventArgs e)
{
this.StartPathForm(2);
}
private void button3_Click(object sender, EventArgs e)
{
this.StartPathForm(3);
}
private void StartPathThread(int currGame)
{
System.Threading.Thread pathThread = new System.Threading.Thread(PathThreadStart);
pathThread.SetApartmentState(System.Threading.ApartmentState.STA);
pathThread.Start(currGame);
this.Close();
}
private void PathThreadStart(object currGame) {
Application.Run(new Path((int) currGame));
}
With this modification, a new thread would be initialized and the Path form will run on it. Then, the Selector form would close immediately. Hope this fit your use.
I'm working on a C# windows application project which requires to display the result of five check boxes in a message.After the user checked all he wants ,I have to display what he checked in a message show box. Here is what I did so far :
private void Display_CheckedChanged(object sender, EventArgs e)
{
if (chkSkis.Checked == true)
{
message = message +chkSkis.Text;
}
if (chkGoogles.Checked == true)
{
message = message +chkGoogles.Text;
}
}
private void displayOrderToolStripMenuItem_Click(object sender, EventArgs e)
{
MessageBox.Show("You chose the following equipments:\n" + message,
"Flyers Sports Club");
}
It is best practice to use StringBuilder. In addition, using the code you posted, if the user un-checks a box, you aren't removing those from the string. I would suggest building the string inside the displayOrderToolStripMenuItem_Click event like so:
private void displayOrderToolStripMenuItem_Click(object sender, EventArgs e)
{
StringBuilder message = new StringBuilder();
if (chkSkis.Checked == true)
{
message.AppendLine(chkSkis.Text);
}
if (chkGoogles.Checked == true)
{
message.AppendLine(chkGoogles.Text);
}
MessageBox.Show("You chose the following equipments:\n" + message.ToString(),
"Flyers Sports Club");
}
I have a TextBox in my winforms. When a user starts typing in it I will like to set the AcceptButton property to call another function. However it is calling another function which is called by a Button in my ToolStrip. To elaborate, here is my code below:
private void locNameTxtBx_TextChanged(object sender, EventArgs e)
{
this.AcceptButton = searchBtn;
}
private void searchBtn_Click_1(object sender, EventArgs e)
{
if (locNameTxtBx.Text != "")
{
List<SearchLocation> locationsArray = new List<SearchLocation>();
var location = locNameTxtBx.Text;
SearchLocation loc = new SearchLocation();
loc.Where = location;
locationsArray.Add(loc);
mapArea.VE_FindLocations(locationsArray, true, true, null);
mapArea.VE_SetZoomLevel(14);
}
else
{
MessageBox.Show("Please Enter Location");
}
}
searchBtn is a Button in the ToolStrip. So, when I try to run this code, I get this error
Cannot implicitly convert type 'System.Windows.Forms.ToolStripButton' to 'System.Windows.Forms.IButtonControl'. An explicit conversion exists (are you missing a cast?)
I have tried casting it as a ToolstripButton like this:
private void locNameTxtBx_TextChanged(object sender, EventArgs e)
{
this.AcceptButton = (ToolStripButton)searchBtn;
}
You could use two delegates and set the delegate to use in the locNameTxtBx_TextChanged method.
private delegate void ToUseDelegate();
ToUseDelegate delegateIfNoText = delegate{
MessageBox.Show("Please Enter Location");
}
ToUseDelegate delegateIfText = delegate{
List<SearchLocation> locationsArray = new List<SearchLocation>();
var location = locNameTxtBx.Text;
SearchLocation loc = new SearchLocation();
loc.Where = location;
locationsArray.Add(loc);
mapArea.VE_FindLocations(locationsArray, true, true, null);
mapArea.VE_SetZoomLevel(14);
}
ToUseDelegate delToUse = delegateIfNoText;
private void locNameTxtBx_TextChanged(object sender, EventArgs e)
{
this.AcceptButton = searchBtn;
if (locNameTxtBx.Text != ""){
delegateToUse = delegateIfNoText;
} else {
delegateToUse = delegateIfText;
}
}
private void searchBtn_Click_1(object sender, EventArgs e)
{
delegateToUse();
}
