Check if process has started
Let's say I have an application, which starts another application (executable) like this:
public void StartExternalProcess()
string path = "D:MyExecutable.exe";
Process process = Process.Start(path);
Executing an .exe file is associated with a small delay. How do I know, when this delay is over, an process
is ready for use (in my case process
is a locally running http server)?
In other words, how do I (if possible) make my method an async Task
, instead of void
?
c# process

Why do you think that making it anasync Task
will accomplish that? I'm not very strong with async programming by any means, but I don't see the connection, so I'm genuinely curious.

Impossible. Only the application knows when it is ready for use (whatever that means). I could code an app, say SleepingBeauty, that waits 100 years and then says that it's ready for use.

For a program with a GUI interface, we can call Process.WaitForInputIdle to wait until it is ready (to process user input), but for your case, the only way to check if it is ready from outside is by sending a request and wait for the response...?

Are you able to change the code of "MyExecutable" to support this?

@MatthewWatson yes, I am. And by the looks of the other answers, this seems like the only way to do it. I just wondered if non-GUI apps had some sort of native support for being ready and idle.
