ScreenSaverConfigureDialog
The ScreenSaverConfigureDialog function receives messages sent to a screen saver's configuration dialog box.
A screen saver that allows user configuration must support this function.
BOOL ScreenSaverConfigureDialog(
HWND hDlg,
| // handle of dialog box
| UINT message,
| // message
| WPARAM wParam,
| // first message parameter
| LPARAM lParam
| // second message parameter
| );
|
|
Parameters
hDlg
Identifies the configuration dialog box.
message
Specifies the message.
wParam
Specifies additional message-specific information.
lParam
Specifies additional message-specific information.
Return Values
If the function processes the message, the return value is TRUE; otherwise, it
is FALSE, except in response to a WM_INITDIALOG message. In response to a
WM_INITDIALOG message, ScreenSaverConfigureDialog should return FALSE if it calls the SetFocus function to set the keyboard focus to one of the controls in the dialog box.
Otherwise, the function should return TRUE, in which case the system sets the
keyboard focus to the first control in the dialog box that can be given the
focus.
Remarks
The dialog box template for the configuration dialog box must have the DLG_SCRNSAVECONFIGURE identifier.
The dialog box procedure is used only if the application specifies the default
window class (WC_DIALOG) for the dialog box. The application uses the default
class if no explicit class is given in the dialog box template. Although the
dialog box procedure is similar to a window procedure, it must not call the DefWindowProc function to process unwanted messages. Unwanted messages are processed
internally by the default dialog box procedure.
The ScreenSaverConfigureDialog function must be exported by including it in the EXPORTS statement in the application's module-definition (.DEF) file.
