Control.Show Method
.NET Framework 4.5
Displays the control to the user.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The following code example displays an about dialog box and temporarily draws a blue square on its surface. This example requires that you have defined a class that derives from Form named AboutDialog.
private void menuItemHelpAbout_Click(object sender, EventArgs e) { // Create and display a modless about dialog box. AboutDialog about = new AboutDialog(); about.Show(); // Draw a blue square on the form. /* NOTE: This is not a persistent object, it will no longer be * visible after the next call to OnPaint. To make it persistent, * override the OnPaint method and draw the square there */ Graphics g = about.CreateGraphics(); g.FillRectangle(Brushes.Blue, 10, 10, 50, 50); }
