How to hide Application Window when its EXE has been called from a Process?

Question

I'm running an application's EXE using a Class Library from a Service. But what i'm attempting to do is hide the application EXE's Window. Here is my code:

In my Class Library's function:-

public class MyClassLibrary
{
    public void MyFunction()
    {
        Process process = new Process();
        process.StartInfo.FileName = "C:\Program Files (x86)\MyFolder\MyApp.exe";
        process.StartInfo.CreateNoWindow = true;
        process.StartInfo.UseShellExecute = false;
        process.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
        process.Start();
    }
}

And this is where i'm calling it from:

class MyClass : ServiceBase
{
    ...
    ...
    ...
    protected override void OnStart()
    {
        MyClassLibrary obj = new MyClassLibrary();
        obj.MyFunction();
    }
}

Despite all of the above, the window is yet seen. Can anyone please suggest a solution?

Thanks and Regards, Siddhant

Answer 1

I have tried your code in does not work but

But when i try it this way it works fine

string filePath = @"C:\Program Files (x86)\Internet Explorer\iexplore.exe";    
ProcessStartInfo pStartInfo = new ProcessStartInfo(filePath );
pStartInfo.WindowStyle = ProcessWindowStyle.Hidden;

Process.Start(startInfo);

Reason it works with Process.Start(ProcessStartInfo) because it associates the given information with a new component as explained on MSDN

Answer 2

I've got the answer guys, thanks to this comment, which i got from Arne's comment at the top of this question.. Apparently it seems that the Process.StartInfo.UseShellExecute was supposed to be set to true.

Thanks everyone for helping out! Cheers!

string filePath = @"C:\Windows\System32\notepad.exe";
ProcessStartInfo pStartInfo = new ProcessStartInfo(filePath);

**pStartInfo.UseShellExecute = true;** 

pStartInfo.WindowStyle = ProcessWindowStyle.Hidden;   
Process.Start(pStartInfo);

Note: Set pStartInfo.UseShellExecute to true otherwise you get an error
