Remarks

To enable a PropSheetProc callback function, use the PROPSHEETHEADER structure when you call the PropertySheet function to create the property sheet. Use the pfnCallback member to specify an address of the callback function, and set the PSP_USECALLBACK flag in the dwFlags member.

PropSheetProc is a placeholder for the application-defined function name. The PFNPROPSHEETCALLBACK type is the address of a PropSheetProc callback function.
