    Mouse Hook Question (Can't determine whether or not button is XBUTTON1 or XBUTTON2)

    Hey.

    I've got a low level mouse hook that is keeping track of button clicks (lbutton,rbutton,mbutton,xbutton). However, when xbutton is pressed, I cannot figure out how to determine whether or not it was the button1 or button2. It doesn't appear to think it's either XBUTTON1 or XBUTTON2.

    Here's the hook (there's some code in there that doesn't matter, for example: the maps).
    Code:
    LRESULT CALLBACK CHook::LLMouseProc(int nCode, WPARAM wParam, LPARAM lParam)
    {
    	if ( nCode == HC_ACTION )
    	{
    		if ( wParam == WM_LBUTTONDOWN || wParam == WM_RBUTTONDOWN || wParam == WM_MBUTTONDOWN || wParam == WM_XBUTTONDOWN ) //Mouse key down...
    		{
    			keytype kt;
    
    			kt.type = TYPE_MOUSE;
    			kt.mouseCode = wParam;
    
    			switch ( wParam )
    			{
    			case WM_LBUTTONDOWN:
    				kt.name = _T("Left Mouse");
    				break;
    			case WM_RBUTTONDOWN:
    				kt.name = _T("Right Mouse");
    				break;
    			case WM_MBUTTONDOWN:
    				kt.name = _T("Middle Mouse");
    				break;
    			case WM_XBUTTONDOWN:
    				
    				int whichbtn = GET_KEYSTATE_WPARAM ( wParam );
    
    				if ( whichbtn == XBUTTON1 )//ugh! always prints out Mouse 5
    					kt.name = _T("Mouse 4");
    				else
    					kt.name = _T("Mouse 5");
    
    				break;
    			}
    			
    			CHook::activeKeys.insert ( make_pair ( wParam, kt ) );
    
    			if ( CHook::KeyIsDropped ( wParam ) ) return 1; //If we need to filter this key, do so
    		}
    		else if ( wParam == WM_LBUTTONUP || wParam == WM_RBUTTONUP || wParam == WM_MBUTTONUP || wParam == WM_XBUTTONUP )
    		{
    			CHook::keyReleased = true; //A key has been released - set the variable to it
    
    			//Remove the key from the map (it has been released now...)
    			map<long, keytype>::iterator i = CHook::activeKeys.find ( wParam );
    			if ( i != CHook::activeKeys.end() )
    			{
    				CHook::activeKeys.erase ( i );
    			}
    		}
    	}
    
    	return CallNextHookEx ( CHook::hMouseHook, nCode, wParam, lParam );
    }
    Any help concerning this topic would be greatly appreciated.


    Thanks,

    I think you should be checking the return of GET_KEYSTATE_WPARAM with MK_XBUTTON1.

    Thanks for the advice.

    Unfortunatly, it still only goes with "Mouse 5" for both of the side mouse buttons.

    I replaced that code with

    Code:
    if ( GET_KEYSTATE_WPARAM ( wParam ) == MK_XBUTTON1 )
    	kt.name = _T("Mouse 4");
    else
    	kt.name = _T("Mouse 5");
    The function GET_KEYSTATE_WPARAM() is always returning the number 523, regardless of which mouse button I am pressing (mouse 4 or 5).

    Is this too much to much to ask of Windows in a low-level hook? I'm thinking it might be because it hasn't gone through any processing yet in the other input threads.

    If there is a way around this please let me know.

    Thanks,

    Matt N

    Have you tried using the GET_XBUTTON_WPARAM macro?

    I've tried going here. There was nothing useful that helped me.

    I'm pulling at straws here since I don't have a mouse with that capability. But anyway, the WM_MOUSEHWHEEL message may be worth checking out.

    To check the get_param return values, you should be &&, not checking ==. At least poking through my copy of winuser.h, GET_KEYSTATE_WPARAM being 523 corresponds to Ctrl + left button + right button (and neither of the x buttons).

    Hey

    I tried the following code, but it still didn't work.

    Code:
    if ( GET_XBUTTON_WPARAM ( wParam ) && XBUTTON2  )
    {
    	OutputDebugString ( _T("Button 2\n") );
    }
    else
    {
    	OutputDebugString ( _T("Button 1\n") );
    }
    I've used a bitwise operator (&), the && sign, and the == sign. None appear to work. I've also used these in combonation with the GET_XBUTTON_WPARAM, GET_KEYSTATE_WPARAM, HIWORD, and LOWORD macros to see if it would work.

    There has gotta be something I'm doing wrong.

    Thanks for the help so far guys, I appreciate it.

    Thanks,

    Hello again.

    I was experimenting with every possible thing I could think of and I finally got a result.

    Code:
    PMSLLHOOKSTRUCT p = (PMSLLHOOKSTRUCT) lParam;
    
    		if ( GET_XBUTTON_WPARAM ( p->mouseData ) == XBUTTON1 )
    		{
    			OutputDebugString ( L"Mouse button 1 pressed.\n" );
    		}
    		else if ( GET_XBUTTON_WPARAM ( p->mouseData ) == XBUTTON2 )
    		{
    			OutputDebugString ( L"Mouse button 2 pressed.\n" );
    		}

    Apparently, the wParam variable has no LOWORD() value, so I found it in the mouseData variable in the mouse hook struct.


    Thanks for your time,

    I did. It only showed the results from the last month. (288 total I think).

    perhaps this was a typo, try using & (bitwise) comparison.
