Question

I have a listbox filled with file paths. Does anyone know how to open the default program for the file when it s double clicked? For example, if one of the items in the listbox says "c: est.txt", how do you open it in notepad? And if it s "c:inetpubwwwrootsitetest est.asp" how can it be opened in the default asp editor? Thanks.

Answer 1

Pass the filename to the System.Diagnostics.Process.Start() method

Answer 2

You can use the Process/ProcessStartInfo classes to execute the file with the default application handler in windows.

For Example:

ProcessStartInfo psi = new ProccessStartInfo();
psi.FileName = "myfile.txt";
Process p = new Process();
p.StartInfo = psi;
p.Start();

Keep in mind that p.Start() can throw exceptions you will have to handle, and different versions of windows will have slightly different behavoir. I know Win7/Vista will pop up the application selector dialog if there isn t a default handler for the file type, but in some versions, you will just get an exception.

Answer 3

This does not completely mimic a double click from windows explorer as is. For example with AutoCAD the correct version is loaded but there is a softlock license manager error when we send the filepath to Process.Start.

System.Diagnostics.Process.Start(dwgFilePath);

To fully emulate a double click from windows explorer we must pass the path to explorer.exe

System.Diagnostics.Process.Start("explorer.exe", dwgFilePath);
