• Robert Horvick Problem with timeSetEvent() for over 16 concurrent timers

  Hello, After using 16 concurrent accurate multimedia timers with the timeSetEvent() API, the 17th call fails! It seems that its impossible to launch over 16 concurrent timers (I'm using VC6 on WinXP/2003). Please help! Thanks. I can also use the CreateTimerQueueTimer() APIs... BUT they are not as accurate as the timeSetTimer()! Is there any way to set the 16 cincurrent timers limitation to a larger number ...Show All

• Sean A. Inheritance loses public function from base class?

  I don't think C++ works like C# or Java in this regard, so I got a bit confused. :-) I've made a custom class based on the MFC UI class CTreeCtrl to add a Set/GetItemData for strings in addition to DWORD's. Now, everything seemed to have went fine, just that the existing SetItemData(HTREEITEM hItem, DWORD dwData) function in the base CTreeCtrl class is lost when using my new class. I sure have the SetItemData(HTREEITEM, const CString& sData ...Show All

  Is this warning buggy in MSVC 7.1 or is it just a stupid warning In the example given here: http://msdn2.microsoft.com/library/f7687yks.aspx It makes sense because the condition, (1) will always be true and the goto will always skip the initialization. But the following code gives me the same C4533 warning and it makes absolutely no sense why it should. #include <iostream> using namespace std; struct TOILET {   &n ...Show All
