我有3個窗戶，有相互利用的活動進行互動。 窗口1和窗口2是相同的;每個只有一個按鈕。的Win32等待事件（synchroniztion）
基本上，我點擊主窗口（程序3）直到一個另外兩個窗口按鈕 被點擊;這究竟是怎麼回事描述了在實驗室：
您需要使用同步控制過程（通過PROGRAM1或2起節目3，通過關閉節目3結束PROGRAM1或2）。注：PROGRAM1和Program2中必須有自己的按鈕，以便點擊他們接受的信號死
我一直在四處尋找，並得到這個至今代碼：
主窗口（程序3） ：

這些都是在相同溶液中;但在不同的項目中（多個項目在一個解決方案中）。
現在的問題是，我似乎無法讓主窗口中打開，當我點擊按鈕 任何一個。我嘗試過很多不同的東西，但沒有一個能夠工作。
任何和所有幫助表示讚賞。提前致謝。
（1）你的第一PROG具有用於處理子控制/菜單命令沒有WM_COMMAND處理程序。 （2）你的第二個程序幾乎是空白的，但是使用字符串常量而不是有效的事件句柄包含無效的'SetEvent（）'調用。你的第三個實際上是第二個的重複，唯一不同是使用不同的（和不正確的）字符串常量的不同的無效SetEvent（）調用。簡而言之，除了向庫存WIN32嚮導生成的項目文件添加十幾行代碼之外，這與您分配的任務無關。 – WhozCraig
