One way to find what these programs are is to open Windows Explorer and look at the Tools > Folder Options > File Types dialog. Every extension that is registered on your system is listed there. In the rest of this example, we'll bring up my choice for playing MPG files - a utility that was provided by my graphics card vendor, ATI.
But, to start this program, with the Process component or anything else, it's necessary to know where it is. This information is available by clicking the Advanced button. You can even copy and paste the path from here into the Process component FileName property in your program. (Make certain you don't change anything while you're doing this!) This gives me MPG file playing coolness, programmatically!
