Hi,

I'm creating two APF applications.
APP-1: Parent Application.
APP-2: Child Application.

Scenario:
APP-2 is invoked from APP-1 based on a condition.
I'm using Process.Start and StartInfo.Arguments to invoke the APP-2 and pass some data to it.

APP-2 takes that data and works on it. There is a Final Data which I want to capture from APP-2 within APP-1 once it's closed.

Following is the code.

C#

string parameter = "INVK://param1/value1/param2/value2/";

			System.Diagnostics.Process launchAuthorApp = new System.Diagnostics.Process();
			launchAuthorApp.StartInfo.FileName = @"C:\APP2.exe";
			launchAuthorApp.StartInfo.Arguments = parameter;
			launchAuthorApp.OutputDataReceived += launchAuthorApp_OutputDataReceived;
			launchAuthorApp.Start();
			while (!launchAuthorApp.StandardOutput.EndOfStream)
			{
				string line = launchAuthorApp.StandardOutput.ReadLine();
			}

How do I set the output for APP-2?

Kinldy respond.

Thanks,
Abhishek

What I have tried:

I Tried

C#

System.Diagnostics.Debug.WriteLine("Output 123");

but not working.
I'm not sure if I'm moving in right direction.

I think you have to redirect the output and use Console.WriteLine.

Mhm... maybe something like this[^] could help you

In your APP-1

C#

var launchAuthorApp = new System.Diagnostics.Process {
    StartInfo = {
          FileName               = @"C:\APP2.exe",
          UseShellExecute        = false,
          RedirectStandardOutput = true,
          Arguments              = "INVK://param1/value1/param2/value2/"
    }
};

launchAuthorApp.Start();

Console.WriteLine(launchAuthorApp.StandardOutput.ReadToEnd());

And in APP-2 (as example)

C#

static void Main(string[] args) {
    Console.WriteLine(args[0]);
}
