L_BOOL LBitmapBase::IsBitmapListLocked()
Determines whether the bitmap list is locked.
Value | Meaning |
---|---|
TRUE | The bitmap list is locked. |
FALSE | The bitmap list is not locked. |
Call this function to check if the bitmap list is locked. If this class object was created using the LBitmapList::GetItem, LBitmapList::GetFirstItem, LBitmapList::GetLastItem, LBitmapList::GetPreviousItem, or LBitmapList::GetNextItem functions, then the bitmap list will be locked until you restore the bitmap to the list using the LBitmapList::SetItem function.
Win32, x64.
