L_ILM_IMPORTBITMAPLIST

Send this message to insert a list of bitmaps into the ImageList Control.

Parameters

wParam

Ignored, use 0.

lParam

Pointer to the LILIMPORTBITMAPLIST structure that contains the list of bitmaps to be inserted.

Returns

Value	Meaning
SUCCESS	Function was successful.
<0	An error occurred. Refer to Error Codes.

Comments

You must set the uStructSize member of the LILIMPORTBITMAPLIST structure before using this message.

The list of bitmaps found in the passed LILIMPORTBITMAPLIST structure (pointed to by lParam) will be inserted into the Image List control starting from nStartIndex to (nStartIndex + nItemsToInsert 1).

After inserting the list of bitmaps successfully into the ImageList control, do not try to free the bitmaps of the passed list (hLists bitmaps). The ImageList control references the hList bitmaps, and does not have a copy of them.

The associated macro is:

L_ImgListImportBitmapList(hWnd, pImportList)

For a complete list of available macros, refer to the Ltlst.h file.
