Introduction
One of the niftiest aspects of Windows Forms is that you can craft them into non-rectangular shapes. Microsoft Windows Media� Player 7 exhibits this feature, and, without doubt, many developers who see this want to incorporate it into their own applications. After much searching, I finally found the answer in MSDN.

Following are the steps to create a simple non rectangular form: Create a bitmap with a non-rectangular shape. This will serve as your form later on, as shown in Fig. 1.

Following are the steps to create a simple non rectangular form:
FormBorderStyle

. BackgroundImage
property of the form to the .bmp you created above. TransparencyKey
property of the form to the background color of the .bmp file. In the case of the example above, you would set it to black. This will make the black portion of the form disappear. Note: Setting the FormBorderStyle
to None
disables the standard functionality provided by the title bar. Thus, you must add custom code to the project to allow the form to be moved, closed, minimized, and maximized. Writing code to close the form

Copy Code
private void Form1_MouseMove(object sender,
System.Windows.Forms.MouseEventArgs e)
{
if (e.Button == MouseButtons.Left)
{
Point mousePos = Control.MousePosition;
mousePos.Offset(mouse_offset.X, mouse_offset.Y);
Location = mousePos;
}
}
Save the application. Press F5 to run it. The form will be shaped like the image you drew at the beginning. Click anywhere on the form and drag it to see the move functionality. Click the Close Form button to close the form. NOTE: Make Sure your VGA Card is set at 16 bit resolution. License
