使用MOCK對象進行單元測試

[轉載自:使用MOCK對象進行單元測試]1.出了什麼問題?

一個微妙的資源泄漏的例子

Things to Remember:在一個獨立的語句中將 new 出來的對象存入智能指標。如果疏忽了這一點,當異常發生時,可能引起微妙的資源泄漏。下面這個函數調用還是可能泄漏資源。為什嗎?processWidget(std::tr1::shared_ptr<Widget>(new Widget), priority());  下面就來說明這是如何發生的。  在編譯器能產生一個對 processWidget

Multibyte VS WideChar Conversion

1. Multibyte shows to us as char*. While in fact, it can be any code page encoding, including gbk, utf8, etc. If a char* represents utf8 characters, we need to handle it specially in below way:// Convert unicode(windows default utf16) to utf8 char*

Some knowledge about why we need to new and delete everything in one module

Essence: Wrap functions to read/write things from another module. Windows keep seperate heaps for debug and release - built DLLs and EXEs. So for example, calling a release DLL from a debug application EXE,  any memory we allocate needs to be

二進位檔案和文字檔

一句話總結:所有各種檔案格式(文本,exe,視頻,圖片),物理上來看,都是二進位檔案;邏輯上來講,由於各自的編碼方式不同,加上文字檔的曆史悠遠,就出現了除了文字檔,其他都統一叫做二進位檔案。同理不同話:"二進位檔案"本來就是一種似是而非的叫法。我們知道,存在有種類繁多的不同類型(格式)的檔案,如文字檔,視頻檔案,影像檔,資料庫檔案....,檔案格式的具體定義取決於應用。不同的檔案格式的主要差別之一就是資訊的編碼不同,而編碼總歸都是"二進位"的,從這個方面看,所有的都是"二進位檔案"。而我們常講的

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。

MS UI Automation原來如此

最近參加了公司的一個program competition,做個小工具。其中涉及到一個盲點。 需求是:在代碼中訪問另一個program的進程,擷取它的視窗控制代碼,並在它的視窗上對某一個控制項進行滑鼠點擊操作以執行相應的命令。google來baidu去,終於有思路了:原來需要用到MS的UI automation library。MS提供了面向c/c++的API,也提供了面向managed code的API。Extract some overview words from below MS
