    Open file in a running application

    Hello
    I have written a program in VB 6.0 that I use to organize files that I have created (in AutoCad), so that I can find them quickly without wasting time. I want to write some code that will open a file when I click on the text box containing the file path/name, I want the file to be opened in a running instance of AutoCad, not Shell out and open AutoCad with the file as a parameter. Is this possible? I hope that I have explained the problem clearly.
    Thank You
    John

    It appears you'll have to set some settings in AutoCAD first (something about single/multiple program instance) before you can open files (via ShellExecute API) in the existing instance. Follow the discussion in this AutoCAD forum.
