Shell function on mouse down

P: 2
I am developing a tool for ArcGIS where I use a Shell call to open a HTML Help file (hh.exe). Each time the user clicks, a new intance of HTML Help will open. Is there a way to recognizze if there is already an instance of HTML Help open and populate the existing window with the new help file page?

Thanks,
banjo

First check whether that file is open or not if not then and then only create the new instance.
Check the below article whether it helps or not.

Thanks, but that did not help much. I am new to VB.NET in case you could not tell. IsFileOpen is not a method or function, or is it? It is telling me that it is not declared. Any ideas?
