How to bring up the “Windows cannot open this file” dialog?

Question

My users can attach documents to various entities in the application. Of course, if user A attaches a .TIFF file, user B may not have a viewer for that type of file.

So I'd like to be able to bring up this dialog:

My application is C# with VS2005.
Currently I do Process.Start and pass in the file name. If no association is found, it throws an exception.

Answer 1

This should do it:

System.Diagnostics.Process p = new System.Diagnostics.Process();
p.StartInfo.FileName = "rundll32.exe";
p.StartInfo.Arguments = "shell32.dll,OpenAs_RunDLL " + yourFileFullnameHere;

p.Start();

Answer 2

Process pr = new Process();
pr.StartInfo.FileName = fileTempPath;
pr.StartInfo.ErrorDialog = true; // important
pr.Start();
