Diagnosing an application spawned from an ASP.NET web application

[James Tsao]

I'm trying to run an external image processing application from a web
application. The function below works for a windows application but
when i try to call it from a web app, the image processing app
starts/stops (it pops up briefly in the task manager). i have no way
of knowing why it closed.

I've also tried running with psInfo.UseShellExecute = false, to no
avail. any help would be greatly appreciated.

public void Run()
{
string program = @"""D:\Program Files\WinImageProcessingApp.exe""";
string args = @"""-o1 option1 -o2 option2""";
ProcessStartInfo psInfo = new ProcessStartInfo(program,args);
Process process = Process.Start(psInfo);
process.WaitForExit();
}

thanks.
JT

most likely the app is trying to open a window, which is not allowed when
started from a service.
