    Open program error notification

    Hi,
    I've almost finished a Terminal/Command Prompt Program that can do most of the
    things a Microsoft or Linux Terminal can do - but I have a problem. I've got it to open
    programs fine, and I can also open their browser to the download page if they don't have it,
    but I need my program to know if there isn't the software so a bit like command prompt where
    it says 'The system cannot find the file test.txt.' and then it'll take them to the website if they like.
    I'd appreciate it if someone gave me advice on what to do.Thank you ,
    Joe

    If you use an API that would open a file, it would tell you if it succeeded or not. What API is dependent upon your platform; there is no standard C++ function for this.

    Sounds like you should stop using System to launch the program, and use CreateProcess instead, and possibly WaitForInputIdle, not to mention CloseHandle.
