I can't agree more. It is a complete waste to have to have two seperate image holding controls. Much of the time you might want to use the same icon in a toolbar and in a ListView/TreeView. Having the same icon contained in two different controls on the same form is a waste of resources.

You could have used a custom imagelist like the ImageManager if the ImageManager supported standard ImageList messages like ImageList_ExtractIcon or ImageList_Draw by subclassing the TreeView and capturing the TVM_SETIMAGELIST message aften assigning the custom imagelist using the TreeView_SetImageList macro. This will not work however as noted above.

The only solution I see is to subclass the treeview and paint the icons onto the treeview nodes yourself from the IconManager. I have not tried it but it should work. It just requires a bit of work.

I thought as much, though I was hoping that someone would have a cunning solution.

I like being able to load implementation specific icons into an application , but don't like loading them into two places (seems a waste). 

I like the inbuilt features the imagemanager has for loading icons (e.g. from an image 'strip') but don't like the fact that you can't then get indivdual icons out.

No, this is not possible. The MS TreeView control can only use the MS ImageList control. When you assign an ImageList to a TreeView the hID is passed to indentify it. The ImageManager doesn't support this and does not comply with standard ImageList commands. So you have to use both.]]> Fri, 11 Mar 2005 04:02:33 +0000 http://forum.codejock.com/forum_posts.asp?TID=1953&PID=5690&title=treeview-icons-from-imagemanager#5690 <![CDATA[TreeView Icons from ImageManager : Is it possible for the MS Tree...]]> http://forum.codejock.com/forum_posts.asp?TID=1953&PID=5684&title=treeview-icons-from-imagemanager#5684 Author: ianp

Is it possible for the MS Tree View to use the icons stored in an ImageManager icons collection?
