Thread: Can't turn off a console close button

I had been using the following code to disable the close button of the console window:

Code:

DeleteMenu(GetSystemMenu(hwndConsole, FALSE), SC_CLOSE , MF_BYCOMMAND);

DrawMenuBar(hwndConsole);

The problem is, I recently strarted using WindowBlinds (which is a neat app that let's you skin windows to look however you want), and this code quit working. Does anyone know an alternate soulution that wouldn't have this issue?

You can try inserting your own WNDPROC hook and intercepting the close messages.

Ok, here's the code I used to attempt your suggestion:

Code:

//I installed the hook with this:

SetWindowsHookEx(WH_CALLWNDPROC, (HOOKPROC) ConsoleProc, NULL, GetCurrentThreadId());

//Here is the code for my hook process:

LRESULT CALLBACK ConsoleProc(int code, WPARAM wParam, LPARAM lParam)
{
	MSG * messagePtr = (MSG *) &lParam;

	if(code < 0)
	{
		CallNextHookEx(consoleWindowHook, code, wParam, lParam);
	}

	if(messagePtr->hwnd == consoleWindow)
	{
		switch(messagePtr->message)
		{

		case WM_CLOSE:
			return TRUE;
			break;
		
		default:
			return FALSE;
			break;

		}
	}

	return FALSE;

}

This doesn't work though, and I'm having trouble figuring out why. Could someone please explain?

Actually, I was refering to:

oldProc = (WNDPROC)SetWindowLongPtr(hwnd, GWLP_WNDPROC, (LONG_PTR)ConsoleProc);

Inside your ConsoleProc, if it's not the message you're looking for, pass it along to the old proc via CallWindowProc().

Give that a go.

No, that didn't work either. Here's what I tried:

Code:

//Set the new window process

consoleOldProc = (WNDPROC)SetWindowLongPtr(consoleWindow, GWLP_WNDPROC, (LONG_PTR)ConsoleProc);

//Here's the processes code:

BOOL ConsoleProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{

	switch(uMsg)
	{

	case WM_CLOSE:
		return TRUE;
		break;
		
	default:
		CallWindowProc(consoleOldProc,
					   hWnd,
					   uMsg,
					   wParam,
					   lParam);
		return TRUE;
		break;

	}

	return FALSE;

}

Interestingly though, the code for the custom process I wrote never seems to actually get executed...

Doh, why didn't I think of that? Ok, GetLastError() is returning Invalid Index right after SetWindowLongPtr() which I guess means that the console doesn't allow it's window procedure to be set through this method. Err... ok, so anyone have any other ideas?

Well, looks like that method won't work after all....

One thing I've noticed regarding the console window, is that windows doesn't like it when you try and mess with it. For the most part it limits you to using built in functions interact with it, and even then it doesn't always work the way it's supposed to. Well, I give up on this one. You can still post a way to do it if you know how, but I'm not gonna hold my breath for anwsers.
