L_ILN_DROPFILES

Sent when files are dropped onto an ImageList Control (for example from Explorer).

Parameter	Description
wParam	idCtrl = (L_INT) LOWORD(wParam) identifier of control.
	wNotifyCode = HIWORD(wParam) notification code.
lParam	pszFilename = (L_CHAR *) lParam pointer to the file that was dropped.

Comments

The parent window of the ImageList will get one L_ILN_DROPFILES notification for each file that is dropped onto the ImageList Control when the control has L_ILS_ACCEPTDROPFILES set.

Example

//NOTE this is not a complete sample, and is meant only to //show you a way in which this message can be used 
L_INT ILN_DROPFILESExample(HWND hCtrl,WPARAM wParam,LPARAM lParam) 
{ 
   if(HIWORD(wParam) == L_ILN_DROPFILES) 
   { 
      if(lParam) 
      { 
         BITMAPHANDLE Bitmap; 
         LILITEM Item; 
         L_INT nResult; 
         THUMBOPTIONS to; 
         to.nWidth = 80; 
         to.nHeight = 80;

         to.bLoadStamp = FALSE; 
         to.bResample = TRUE; 
         nResult = L_CreateThumbnailFromFile((L_TCHAR *)lParam, 
         &Bitmap,0, &to, 
         NULL, NULL, NULL, NULL); 
         if(nResult == SUCCESS) 
         { 
            Item.uStructSize = sizeof(LILITEM); 
            Item.pText = (L_TCHAR *)lParam;
