Do you mean something like this: System.Diagnostics.Process.Start(yourFileName)

I got this info from here as an FYI:
http://www.codeproject.com/KB/vb/VBFileAssociation.aspx[^]

So, access the registry and open up the HKEY_CLASSES_ROOT section.

Then, find the key for .pdf

The default value lists the type of file that it is.

Then, open up the key for that type of file in the same section.

This key will have a subkey of shell which has a subkey of open which has a subkey of command.

This command lists the default program used to open the file (in my case, it lists "C:\Program Files\Adobe\Acrobat 9.0\Acrobat\Acrobat.exe" "%1").

And you didn't specify which version of VB (VB6 or .Net) but here's an article that explains accessing the registry using both: Accessing the Registry with VB6 and VB.NET[^]
