How can I tell if a process has a graphical interface?

Question

I\'m using automation to test an application, but sometimes I want to start the application via a batch file. When I run \"process.WaitForInputIdle(100)\" I get an error:

I was think along the lines of this, Still ugly but trys to avoid exceptions.

Process process = ...

bool hasUI = false;

if (!process.HasExited)
{
    try
    {
        hasUI = process.MainWindowHandle != IntPtr.Zero;
    }
    catch (InvalidOperationException)
    {
        if (!process.HasExited)
            throw;
    }
}

if (!process.HasExited && hasUI)
{

    try
    {
        process.WaitForInputIdle(100);
    }
    catch (InvalidOperationException)
    {
        if (!process.HasExited)
            throw;
    }
}
