This is a Function which displays the Browse directory dialogue and returns a path as a string. Unlike the usual shell command, this code works even on machines without the Active Desktop or IE 5 installed.
Inputs
lnghWndOwner as Long, the hWnd of the Owner form
Assumes
I think you need IE 4 on the machine, but not 100% sure. Call it like this :
strSelectedFolder = BrowseForFolder(me.hwnd)
Code Returns
BrowseForFolder as String, the path to the selected folder
