安全執行緒問題

Threading safety means: multiple   threads   can   call   the   same   method   at   the   same   time   without   corrupting   your   data/resources如果你的代碼所在的進程中有多個線程在同時運行,而這些線程可能會同時運行這段代碼。如果每次運行結果和單線程啟動並執行結果是一樣的,而且其他的變數的值也和預期的是一樣的,就是安全執行緒的。

MFC Is MVC

關於MVC結構模式無須多言,如所示:

棧,堆和靜態儲存區的區別

1)   堆是由低地址向高地址擴充,棧是由高地址向低地址擴充。2)   堆是不連續的空間,棧是連續的空間。3)   在申請空間時,棧的分配要比堆的快。對於堆,先遍曆存放空閑儲存地址的鏈表、修改鏈表、再進行分配;對於棧,只要剩下的可用空間足夠,就可分配到,如果不夠,那麼就會報告棧溢出。4)   棧的生命期最短,到函數調用結束時;靜態儲存區的生命期最長,到程式結束時;堆中的生命期是到被我們手動釋放時(如果整個過程中都不手動釋放,那就到程式結束時)。

VS資源(基礎)

1. 資源BasicVisual C++ 支援十種資源:加速鍵、位元影像、游標、對話方塊、HTML、表徵圖、菜單、串表、工具條和版本資訊。            各種資源就是堆資料而已,最終都會被嵌入到EXE檔案裡的資料區中。需要的時候就通過函數載入到記憶體中使用。和資料庫一樣的。各種資源通過ID來唯一確 定,就像資料庫用關鍵字來確定一樣。不同的資源由於類型不一樣可以使用等值的ID,如同資料庫裡的每一個表單裡的關鍵字值不唯一,但不同表單的關鍵字是允 許一樣的。 2. Next ID Issue

(收藏)MFC中的訊息處理

[轉自:http://blog.csdn.net/gxj1680/archive/2009/03/17/3998923.aspx]視窗訊息概述:     所有的視窗訊息的基本形式都是一樣的,有3個部分:(1).一個不帶正負號的整數,包含訊息的實際內容.(2)WPARAM,一個4位元組整數.(3)LPARAM,一個4位元組參數.無符號數是實際訊息.     含MFC在內的任何WINDOWS程式的核心都是訊息泵.訊息泵是一個迴圈,它取出訊息並將訊息送給恰當的視窗訊息處理函數.下面是個訊息泵的樣本:

理解白平衡

【http://dslr.abang.com/od/photography/a/custom_wb.htm】白平衡的意思是“相機把某種顏色認為是白色”的能力。因此手動白平衡可以把任何顏色定義為相機認為的白色。總的來說,如果你希望你的畫面獲得偏暖(色溫較低)的畫面,那麼你就可以將藍、綠等冷色定義為“白色”。反之,如果你希望你的畫面獲得偏冷色調(色溫較高)的畫面,你可以將橙、黃等暖色定義為“白色”。

建立純資源dll(vc++)

建立純資源 DLL純資源 DLL 是僅包含資源(標、位元影像、字串和對話方塊)的 DLL。使用純資源 DLL 是在多個程式之間共用同一組資源的好方法。提供其資源被針對多種語言進行本地化的應用程式也是一種好方法(請參見 MFC 應用程式中的本地化資源:附屬 DLL)。若要建立純資源 DLL,請建立一個新的 Win32 DLL(非 MFC)項目,並將資源添加到此項目。在“建立項目”對話方塊中選擇“Win32 項目”,並在“Win32 項目嚮導”中指定 DLL 項目類型。為 DLL 建立一個包含資源(
