C++控制檯「屏幕截圖」問題

我有這個代碼，屏幕捕捉，它應該工作，但我不知道問題在哪裏它說「沒有目標架構」，我認爲它的位事情..即時運行Windows 7 32位，和IM使用Visual Studio的2012年提前謝謝你C++控制檯「屏幕截圖」問題

計算器，這是我所得到的..我不知道我做錯了

您可能需要移動的#include''以上的#include''。看到[這個前面的問題在SO]（http://stackoverflow.com/questions/4845198/fatal-error-no-target-architecture-in-visual-studio-2010） – Dan

您需要包括WINDOWS.H WINDEF.H

謝謝先生，它的工作很好 – ExtraMt

你需要進入爲您的項目配置，並設置目標架構。在你的情況下，我認爲這是x86。
