Follow this step: 1.You can download Windows® API Code Pack for Microsoft® .NET Framework 2.See how the "\Windows API Code Pack 1.1\source\WindowsAPICodePack\Shell\CommonFileDialogs\CommonFileDialog.cs" make use of IFileDialogCustomize from com. 3.If you want to add a stuff to the "Open" dropdownlist, you can write code below customize.EnableOpenDropDown(0); customize.AddControlItem(0, 0, "Open as XXX"); customize.AddControlItem(0, 1, "Open in YYY"); Note: 0 is the Open Button ID After user selected, you can get the selectedIndex through this.customize.GetSelectedControlItem(0, out openindex); Note again: 0 is the Open Button ID And then you can do something imply with filename and this openindex.

Crow, hey I found the problem, everytime I would build it would seem to recreate the makefile. I had a line in the makefile as follows: "C:\Program Files\Microsoft Visual Studio .NET 2003\Vc7\bin\nmake.exe" /nologo that particular line was causing problems. I am building in the Rational Rose Environment and within a particular field called CodeGenMakeInsert on a C++ Generation tab for a Component Specification I had that line inserted. I know that it may mean nothing to you but it fixed the problem just wanted you to know. Thanks for you help. It took me a while to figure it out but I think it makes sense after looking at another generated makefile from the same environment that didn't have a line like that. Sorry for the ramble hope this helps someone else out. :doh:

If VC++ 6.0, use the ClassWizard and set up a member function for WM_LBUTTONDOWN. If VC++ 7.1, don't use the Classwizard ('cause it 'taint there) and set a handler for WM_LBUTTONDOWN If your using VC .NET, I haven't the clue. It's too safe for me anyway.;P (In .NET it's probably in the System.Computer.Actions.Mouse.MouseActions.ButtonActions.PressedActions.LeftButton.Down namespace or something hideously long like that) -- modified at 20:25 Wednesday 12th April, 2006

the hard way would be hooking ZwQueryDirectoryFile and restricting your diretories. :P I'm sure there is an easier way gabby

I am not using MFC, I am actually using a Win32 project.
