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:

Answer 1

You can simply try and catch the exception:

Process process = ...
try
{
    process.WaitForInputIdle(100);
}
catch (InvalidOperationException ex)
{
    // no graphical interface
}
