display icon associated with program

[smchristensen]

Is there a way to make a treeview control show the icon that is associated with a file without loading all the pictures in a imagelist? Maybe by using explorer?

[epelyavski]

I think you don't have to load all pictures in a imagelist. You can use ListImages.Add method:


...
imgList.ListImages.Add , "File1", picPicture.Picture
lstBrowser.ListItems.Add , , "File Name", "File1"
...




Another question is how to get those icons associated with files. By using the Registry? Any ideas?

Next question!
