C# WinAPI Clicking on menu items

[BarrMan]

I'm trying to click on a menu item inside a program called Media Subtitler and whatever I'm trying to do it's not working.

First, I tried to use the function GetMenu but it returned IntPtr.Zero. Then, I tried using the ALT key + using the first letter of my menu (F stands for file) but it did nothing. Then, I tried using a simple MOUSEDOWN and MOUSEUP messages but again, it did nothing (I also tried creating a loop that clicks on everything in that range but there was no click in that area).

What I clearly know is that I'm working on the correct window.

What am I doing wrong?

If someone wants to test it out you can download Media Subtitler for free and it doesn't weight that much.

Also, Here's the code I've been testing:

Process p = Process.Start(@"C:\Program Files\DivXLand\Media Subtitler\MediaSub.exe");
        p.WaitForInputIdle(1500);
        Thread.Sleep(3000);
 
        SetForegroundWindow(p.MainWindowHandle);
        ShowWindow(p.MainWindowHandle, SW_MAXIMIZE);
 
        IntPtr handle = p.MainWindowHandle;
 
        SendMessage(handle, WM_NCHITTEST, 0, MakeLParam(18, 29));
 
        //for (int i = 0; i < 200; i++)
        //{
        //    for (int x = 0; x < 200; x++)
        //    {
        //        SendMessage(p.MainWindowHandle, WM_LBUTTONDOWN, 0, MakeLParam(i, x));
        //        SendMessage(p.MainWindowHandle, WM_LBUTTONUP, 0, MakeLParam(i, x));
        //    }
        //}
        //IntPtr menuItems = GetMenu(p.MainWindowHandle);
        return;
        //SendMessage(p.MainWindowHandle, WM_COMMAND, 6, 0);
        SendMessage(p.MainWindowHandle, WM_KEYDOWN, VK_MENU, 0);
        SendMessage(p.MainWindowHandle, WM_KEYUP, VK_MENU, 0);
        SendMessage(p.MainWindowHandle, WM_KEYDOWN, VK_F, 0);
        SendMessage(p.MainWindowHandle, WM_KEYUP, VK_F, 0);

Thanks for any help!
