Use the TreeView control in A program, and has the binding ImageList, in B programs need to grab A TreeView control of associated ImageList images in the program, by calling the Comctl32. ImageList_GetImageCount function under the DLL (ImageList handles have caught in A program, no fault,), but anyway have no results, always returns to zero, I have been tested in A program, you can catch the right return value, also suspect is not crawl across process at the beginning, but the system provides the function of the return value is an int, parameter is the handle to ImageList, so to ask you this may also is what problem,
Enclosed I search on bing an article, and I the same, but in the end also didn't see how to solve,
