ScreenSaverProc
The ScreenSaverProc function receives messages sent to the specified screen saver window.
LONG ScreenSaverProc(
HWND hWnd,
| // handle of screen saver window
| UINT message,
| // message
| WPARAM wParam,
| // first message parameter
| LPARAM lParam
| // second message parameter
| );
|
|
Parameters
hWnd
Identifies the window.
message
Specifies the message.
wParam
Specifies additional message-specific information.
lParam
Specifies additional message-specific information.
Return Values
The return value is the result of the message processing and depends on the
message sent.
Remarks
A screen saver's ScreenSaverProc window procedure should use the DefScreenSaverProc function instead of the DefWindowProc function to provide default message processing. The DefScreenSaverProc function passes any messages that do not affect screen saver operations to DefWindowProc.
The ScreenSaverProc function must be exported by including it in the EXPORTS statement in the application's module-definition (.DEF) file.

Nostalgia .Net |

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
