I need to add two buttons to a VB app. These buttons need to open Internet Explorer and Adobe Acrobat. I would like to know is there any way to open their .exe's without giving the total, specific path? I've gotten it to work with the shell command but I need to hard code the entire path to the exe. This is not acceptable in the application since clients could have these particular executables in several locations, depending on the version. Can anyone help?
