Routine Description:
Retrieves the currently selected cover page name and returns its flags.
Provides both its full path and short name and indicates if it is a server cover page or not.
If the cover page is a personal cover page the returned cover page name is a full path to it.
If the cover page is a server cover page the returned cover page is just the file name.
Arguments:
pCPInfo - Points to cover page information
hwndList - Handle to the list window
lptstrFullPath - Points to a buffer for storing the selected cover page full path.
if lptstrFullPath is NULL the full path is not returned.
cchstrFullPath - The size of lptstrFullPath in TCHARs.
lptstrFileName - Points to a buffer for storing the selected cover page file name.
This parameter can be NULL in which case the file name will not be provided.
cchstrFileName - The size of lptstrFileName in TCHARs.
pbIsServerPage - Points to a BOOL variable that is set to TRUE if the selected cover page is a server cover page.
