Close Notepad Window Without Saving Changes

Question

I would like to close notepad file without prompting "Would you like to save changes" dialog box. I tried:

SendMessage(handle, 0x0010, IntPtr.Zero, IntPtr.Zero);

But asks me whether I'd like to save changes or not. Also DestroyWindow(HWND) doesn't work.

How to overcome this problem?

Thanks a lot...

What are you attempting to achieve in doing this? (i.e why do you need to use notepad and not a control within your own program etc) — Sayse, Sep 11 '14 at 06:23
@Sayse It seems he's controlling a Notepad process/window from his own process. — mostruash, Sep 11 '14 at 06:28
@Mesut btw you should use constants instead of explicit values like `0x0010` if you want your question to be answered. It's too much hassle to look for what constants they actually refer to. — mostruash, Sep 11 '14 at 06:30

If you don't care about the data on notepad then simply kill its process.

[DllImport("user32.dll", SetLastError=true)]
static extern uint GetWindowThreadProcessId(IntPtr hWnd, out uint processId);

Now kill the process using its process id

Process p = Process.GetProcessById(processId);
p.Kill();

Just to add to the answer posted by @prem, there is absolutely no need for using APIs. .NET already includes everything to do this like in the example below.

var processes = Process.GetProcessesByName("notepad");
foreach (var process in processes)
    process.Kill();
