Examples

The following example illustrates the creation of new ColorDialog. This example requires that the method is called from within an existing form that has a TextBox and Button placed on it.

private:
   void button1_Click( Object^ /*sender*/, System::EventArgs^ /*e*/ )
   {
      ColorDialog^ MyDialog = gcnew ColorDialog;
      // Keeps the user from selecting a custom color.
      MyDialog->AllowFullOpen = false;
      // Allows the user to get help. (The default is false.)
      MyDialog->ShowHelp = true;
      // Sets the initial color select to the current text color.
      MyDialog->Color = textBox1->ForeColor;
      
      // Update the text box color if the user clicks OK 
      if ( MyDialog->ShowDialog() == ::System::Windows::Forms::DialogResult::OK )
      {
         textBox1->ForeColor = MyDialog->Color;
      }
   }

private void button1_Click(object sender, System.EventArgs e)
 {
    ColorDialog MyDialog = new ColorDialog();
    // Keeps the user from selecting a custom color.
    MyDialog.AllowFullOpen = false ;
    // Allows the user to get help. (The default is false.)
    MyDialog.ShowHelp = true ;
    // Sets the initial color select to the current text color.
    MyDialog.Color = textBox1.ForeColor ;
    
    // Update the text box color if the user clicks OK 
    if (MyDialog.ShowDialog() == DialogResult.OK)
        textBox1.ForeColor =  MyDialog.Color;
 }

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    Dim MyDialog As New ColorDialog()
    ' Keeps the user from selecting a custom color.
    MyDialog.AllowFullOpen = False
    ' Allows the user to get help. (The default is false.)
    MyDialog.ShowHelp = True
    ' Sets the initial color select to the current text color,
    MyDialog.Color = TextBox1.ForeColor

    ' Update the text box color if the user clicks OK 
    If (MyDialog.ShowDialog() = Windows.Forms.DialogResult.OK) Then
        TextBox1.ForeColor = MyDialog.Color
    End If
End Sub

Remarks

When set to false, the associated button in the dialog box is disabled and the user cannot access the custom colors control in the dialog box.
