Hi Experts,
I'm looking for something like AfxGetMainWnd in c# so that I can set the window title.  I'm in a panel and this panel could be in another panel or in a child window, etc.....  Is there a way to do this in c#?

Thanks!
Mike

Application.OpenForms[0].Text = "Hello.";

should always refer to your first opened form, the applicaiton window.  That will change the title to "Hello."

Good luck :)

Oh, and just in case for some reason [0] doens't refer to your main form you can use this to change the title based on the type of form (assuming you only have one of your main form open at any time).  If you have multiple of the same form, you can change getType() and typeof() and use Name == "your form name" to explicitly target a specific form you've made by name.  If this were your main form though, its started in your program file and allocated without a name, you would have to save the name or explicitly name it and pass it in to use the name method.

I think the first post will cover the problem though :)

for (int i = 0; i < Application.OpenForms.Count; ++i)
            {
                if (Application.OpenForms[i].GetType() == typeof(Form1))
                {
                    Application.OpenForms[i].Text = "Hello.";
                    break;
                }
            }

Do you just want the "active" form?

    Form.ActiveForm.Text = "Hello!";

Or the current form?

    this.Text = "Hello!";

I want only the main window (the one that opens as soon as my app starts)...

You could STORE the reference to your starting form as a static member in program.cs:

    static class Program
    {

        public static Form MainForm = null;

        ///
        /// The main entry point for the application.
        ///
        [STAThread]
        static void Main()
        {
            Application.EnableVisualStyles();
            Application.SetCompatibleTextRenderingDefault(false);
            Program.MainForm = new Form1();
            Application.Run(Program.MainForm);
        }

    }

Now you can use "Program.MainForm" from anywhere in the app:

        private void button1_Click(object sender, EventArgs e)
        {
            Program.MainForm.Text = "Hello Starting Form!";
        }
