dynamic CImageList icons - possible? [modified]
-
I have a CTreeCtrl and an associated CImageList. Is there any way I can load images into the CImageList at runtime (e.g. from an .ico file supplied by the user) without them being hardcoded into the executable files ? -- modified at 14:21 Thursday 4th January, 2007

You can add/remove images from image lists dynamically. Check out CImageList::Add() (::ImageList_AddIcon()), ::LoadImage(), etc. Mark

Yes - although if dealing with a lot of images it is better to initially size the ImageList control to hold a bunch of images. The
CImageList::GetImageInfo(...)function or theImageList_GetImageInfo(...)macro can be used to write data into the images maintained by the ImageList control. Peace!-=- James

Thanks to everyone for the posts. I know these functions, but they don't realy explain how to load icons from files or "external" data sources - this is what I meant by dynamic (the icons aren't already hardcoded as resources in the executables). I found the functions I was looking for, which are: ExtractIcon() - load icon from disk CreateIconFromResourceEx() - load icon from memory Sorry, I think I should have explained what I was after a bit better..

I think you need to
SHGetFileInfoto get information about file and... and also if you dont know about CImageList and its functions search on the codeproject it has a lot of good articles :)
