Mouse Hook Question (Can't determine whether or not button is XBUTTON1 or XBUTTON2)
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).
Any help concerning this topic would be greatly appreciated.
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...
kt.type = TYPE_MOUSE;
kt.mouseCode = wParam;
switch ( wParam )
kt.name = _T("Left Mouse");
kt.name = _T("Right Mouse");
kt.name = _T("Middle Mouse");
int whichbtn = GET_KEYSTATE_WPARAM ( wParam );
if ( whichbtn == XBUTTON1 )//ugh! always prints out Mouse 5
kt.name = _T("Mouse 4");
kt.name = _T("Mouse 5");
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 );
