I am using My.Computer.Network.DownloadFile to download a file from an FTP server in a VB 2008 WinForm app. I have the ShowUI argument set to TRUE so that it shows a progress window. However, when I run the code, it show's the progress window but the progress bar doesn't increment. The file eventually downloads and the progress window dissapears, but at no point does the progress bar in this window increment at all. Any ideas why?
