PropSheetPageProc
The PropSheetPageProc function specifies an application-defined callback function that a property
sheet calls when a page is created and when it is about to be destroyed. An
application can use this function to perform initialization and cleanup operations
for the page.
UINT CALLBACK PropSheetPageProc(
HWND hwnd,
|
| UINT uMsg,
|
| LPPROPSHEETPAGE ppsp
|
| );
|
|
Parameters
hwnd
Reserved; must be NULL.
uMsg
Action flag. This parameter can be one of the following values:
Value
| Meaning
| PSPCB_CREATE
| A page is being created. Return nonzero to allow the page to be created or
zero to prevent it.
| PSPCB_RELEASE
| A page is being destroyed. The return value is ignored.
|
ppsp
Pointer to a PROPSHEETPAGE structure that defines the page being created or destroyed.
Return Values
The return value depends on the value of uMsg.
