CommonDialog Class
Assembly: System.Windows.Forms (in system.windows.forms.dll)
Inherited classes are required to implement RunDialog by invoking ShowDialog to create a specific common dialog box. Inherited classes can optionally override HookProc to implement specific dialog box hook functionality.
The following code example uses the ColorDialog implementation of CommonDialog and illustrates creating and showing a dialog box. This example requires that the method is called from within an existing form, which has a TextBox and Button placed on it.
Private Sub button1_Click(sender As Object, e As System.EventArgs) 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() = DialogResult.OK) Then textBox1.ForeColor = MyDialog.Color End If End Sub 'button1_Click
protected void button1_Click(Object sender, System.EventArgs e)
{
ColorDialog myDialog = new ColorDialog();
// Keeps the user from selecting a custom color.
myDialog.set_AllowFullOpen(false);
// Allows the user to get help. (The default is false.)
myDialog.set_ShowHelp(true);
// Sets the initial color select to the current text color.
myDialog.set_Color(textBox1.get_ForeColor());
// Update the text box color if the user clicks OK
if (myDialog.ShowDialog().Equals(get_DialogResult().OK)) {
textBox1.set_ForeColor(myDialog.get_Color());
}
} //button1_Click
