Currently running this code to open Business Vision (an application written by someone else that i don’t have access to the code of):

ProcessStartInfo myProcessStartInfo = new ProcessStartInfo(BusinessVisionPath);
myProcessStartInfo.UseShellExecute = false;
myProcessStartInfo.RedirectStandardOutput = true;
myProcess.StartInfo = myProcessStartInfo;
myProcess.Start();

StreamReader myStreamReader = myProcess.StandardOutput;
Boolean done = false;
while (done == false)
{
    int s = myStreamReader.Read();
    Console.WriteLine(s);
    if (s == -1)
    {
        done = true;
        Process IProcess = new Process();
        ProcessStartInfo IProcessStartInfo = new ProcessStartInfo(QuickPrinterPath);
        IProcessStartInfo.WindowStyle = ProcessWindowStyle.Maximized;
        IProcess.StartInfo = IProcessStartInfo;
        IProcess.Start();
    }

}
myProcess.Close();
Console.ReadLine();

Anyways,

this code currently opens my printer program when BusinessVision closes.

Questions:

  1. How (if possible) can i open my program when a certain message box pops up within BV (“Are you sure you want to print an invoice”?)
  2. Is it possible to get any data from the application ? like raw data that i can parse through as it runs or something?

    You might want to look into Microsoft’s UI Automation. It allows you to read data from the windows of other applications, and interact with other applications’ UI programmatically. I used this a couple years ago to automate a bunch of tests on an old VB6 app we had. My code would find the main window of the application, then drill down to the menus/controls/etc that I was interested in. From there I could automate clicks and keystrokes, and then scrape the text/data I wanted from the labels in various windows. I could then pull the data into my .NET app and do what I wanted with it.

    In your case you would need some always-running app (such as a Windows service) to constantly monitor the BV program and detect when the message box appears, and then react accordingly by launching your program.

    It takes a fair amount of work to understand and get working, but it’s very powerful. There are free apps out there that will make it easier to browse the visual hierarchy of windows and see what kind of information is available. Check out Microsoft’s UISpy:
