Windows Message ID constants
By Anthony Baraff.
The .NET base classes manage to insulate the programmer from many of the details of how applications interact with the underlying operating system, but in order to implement advanced UI functionality Microsoft leaves you no option but to interoperate with windows plumbing. The
IMessageFilterinterface requires you to use the
System.Windows.Forms.Messagestruct which wraps a windows message. The
Msgproperty corresponds to an int value that stores a constant indicating the type of message, Windows is sending your application. To my knowledge, Microsoft has not incorporated an enumeration with the commonly used constants. So, I stripped all of the messages I could find in the CommCtrl.h and WinUser.h header files and created an enum. I hope that you find it useful.
public enum WindowsMessages: int
WM_NULL = 0x0000,
WM_CREATE = 0x0001,
LM_SETITEM = (WM_USER + 0x302),
LM_GETITEM = (WM_USER + 0x303)
