Processes Windows messages.

Namespace: System.Windows.Forms

	ref Message msg
)

Parameters

Remarks

All messages are sent to the WndProc method after getting filtered through the PreProcessMessage method.

The WndProc method corresponds exactly to the Windows WindowProc function. For more information about processing Windows messages, see the WindowProc function in the Platform SDK documentation at http://msdn.microsoft.com.

Inheriting controls should call the base class's WndProc method to process any messages that they do not handle.
