A File Manager extension sends an FM_GETFILESEL message to retrieve information about a selected file from the active File Manager window (either the directory window or the Search Results window).
FM_GETFILESEL
wParam = (WPARAM) index; // index of selected file
lParam = (LPARAM) (LPFMS_GETFILESEL) lpfmsgfs; // file data
Parameters
index
Value of wParam. Specifies the zero-based index of the selected file to retrieve.
lpfmsgfs
Value of lParam. Points to an FMS_GETFILESEL structure that receives information about the selection.
Return Values
The return value is the zero-based index of the selected file that was retrieved.
Remarks
An extension can use the FM_GETSELCOUNT message to get the count of selected files.
