Question

Given the code. when the button is clicked nothing happens , i get no debug message etc in visual studio. However if i were to double click the .jar file in its folder i am able to run it. Anyone have any idea why?
Looking at Task manager when the button is clicked. javaw.exe is created but nothing happens.

private void btnKinderPuzzle_Click(object sender, RoutedEventArgs e)
{
    // Check if this program is opened
    if (IsProcessOpen("MTPuzzle"))
    {
        MessageBox.Show("KinderPuzzle is already running", "Kinder Package", MessageBoxButton.OK, MessageBoxImage.Information);
    }
    else
    {
        Process.Start(Directory.GetCurrentDirectory() + "\\Puzzle\\PuzzleGame\\MTPuzzle.jar");
    }
}

Answer 1

Process.Start("java.exe", 
              Path.Combine("-jar " + Directory.GetCurrentDirectory(), 
                           "Puzzle\\PuzzleGame\\MTPuzzle.jar"));
