需求是這樣的：
如圖中XSheel是一個類似于串口或遠程登陸服務器的除錯軟體，視窗不斷接受來自服務器端的資訊，并列印出來。而現在我需要獲取這個輸出框區域的文本內容。（或者僅獲取最后100個字符存到CString str0；中）
使用spy++獲取了相關的內容，發現輸出框區域不是edit控制元件，而是AfxFrameOrView110。
已經獲得句柄記為hCmdWnd1，ID=0x0000E900。并且可以通過句柄向視窗成功發送了文本資訊。
但使用 ::SendMessage(hCmdWnd1,WM_GETTEXT,20,(LPARAM)(LPCTSTR)str0);無法獲取文本內容。
請問各位有什么思路嗎？用管道的話該怎么做呢，用管道獲取過CMD控制臺的資訊，但是還是不知道怎么獲取這個的。
