L_INT LImageListControl::GetSelectCount(L_VOID)
Gets the current number of selected items in the ImageList Control.
Value | Meaning |
---|---|
>= 0 | The number of selected items. |
<0 | An error occurred. Refer to Return Codes. |
Call this function, before calling LImageListControl::GetSelectedItems, to get the number of selected items. You can then use this number for allocating storage for the LILITEM structures.
Win32, x64.
