Question

I am learning more C# programming and have developed an application using Ogre. However the only method I have of exiting the application when running it is, ALT+F4.

I have put in the code a method to Exit with keyPress ESC. However, Visual C# Express is throwing error, and not letting me use ProcessCmdKey. :\

Help?

using System;
using System.Windows.Forms;

    protected override bool ProcessCmdKey(ref LogMessageLevel msg, Keys keyData)
    {
        if (keyData == Keys.Escape) this.Close();
        return base.ProcessCmdKey(ref msg, keyData);
    }

More standard way is adding close button to the form then set this button as the Form Cancel button.

By setting it as Cancel button, it will be triggered automatically upon pressing ESC key.
