{
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;
