c++ - Why does EnumWindows return more windows than I expected? -

-

In VC ++, I use EnumWindows (...), GetWindow (...), and GetWindowLong () To do this, check the windows list and check whether the window is the top window (not in the form of a second window owner), and what the window is showing (WS_VISIBLE) However, although my desktop is showing only 5 windows, this EnumWindows I'm giving 50 windows, how odd it is! Any windows geek here please help me clarify ...

"post-text" itemprop = "text">

To list only windows in the taskbar The way (or similarly in the alt-tab box) is described by Raymond in this article on MSDN Blog:

and it is a super function to check whether the window is in the Alt tab Has been shown: 

  BOOL EASAT TABWANDO (HWND HWD) {TITLEBARINFO ti; Hwd hwdt, hwdwow = null; If (Ivindo Wausible (HWND)) will change wrong; HwndTry = GetAncestor (hwnd, GA_ROOTOWNER); While (hwndTry! = HwndWalk) {hwndWalk = hwndTry; HwndTry = GetLastActivePopup (hwndWalk); If (iSwindOvisable (HWDTE) break); } If (hwndWalk! = Hwnd) return false; // removes ti.cbSize = sizeof (ti) following some work tray program and "program manager"; GetTitleBarInfo (HWD, and TI); If (TI. RGSTET [0] and STATE_SYSTEM_INVISIBLE return FALSE; // Toolbars should not be displayed either, they do not appear in the // taskbar if GetWindowLong (hwnd, GWL_EXSTYLE) and WS_EX_TOOLWINDOW return FALSE; Return TRUE; }

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

memcached - Django cache performance -

-
We are now using Redis for in-memory cache for our Django application (we used the first memcatch The difference in performance is no big, and we're using Redis because the disc dump feature). The problem is that Django cache's performance in my view - terrible, we have a view with 102 cache hits (no miss), and it has 81 ms (only the cash part, which is with the DJBugBug toolbar Is measured). In my opinion - this is a very long time, I know, asking for a question for DB can be 10x more (or 100x) time, but that is also not good with cash performance of that fact. We are running radis (and the first memacatch) on different hosts, connected to the local network with other servers. Is there a way to maximize cache performance in Django? Instead of displaying problem cache, there is a possibility of the number of items to be received for each page 102 Cash calls mean long time lost due to network latency. With full control of the code, you may be able to fix it with m...
