Starting a Process

[dschu012]

When using the following code

p = Process.Start("firefox", "-new-window http://google.com/");
p.WaitForInputIdle();
MessageBox.Show(p.HasExited.ToString());

The p.HasExited is always true and I can't get any more info from the process. I want to be able to get the MainWindowTitle and the MainWindowHandl e but I can't figure out a way to do this because if I try to it says the process has exited.

It may never hit the InputIdle state until the process has closed.

Is there an asynchronous start method?

Dont know exactly what you guys mean I am kind of a noob at this stuff but is this the way I should be approaching starting a process and being able to get the Handle of the main window of a process or is there a better way?

Your problem is that you probably have another Firefox window already open. In that case, your new process will just notify the first process instance and die immediately.

Try to open several Firefox windows, and then check Process.GetProc essesByName("fi refox"); - it will return only a single Process instance. Also try to test your program with all firefox windows initially closed.

What is it exactly you are trying to do? It doesn't seem like you want to open an instance of Firefox just to get its main window name, so maybe there is something else you could do?

firefox doesn't seem to like letting you open up an actual other process. (Unless you switch profiles with the -P (profilename) command argument)

yeah I've noticed that. But anyways I was trying to get the Handle of the process so I could use PostMessage from Win32 API to automate some tasks without the browser being active. However I have seemed to have gotten the same thing accomplished with the webBrowser control and without using PostMessage.
