(編輯:所以我終於成功地使代碼格式正確位置 - 只需插入4個空格開頭)
享受它,我花了相當長的時間來獲得它的工作..但現在我覺得已經達到了一個新的水平。 :)
(請告訴我如何讓它正確地格式化 - 無論是報價和代碼的失敗對我)

編輯: 這裏http://www.andreas-reiff.de/2011/06/c-speicher-anderen-prozess-befullen-lassen-checken-ob-ein-button-gedruckt/與可讀的代碼,並在一個陌生的,外語的解釋..但是代碼註釋是英語。希望你覺得它有用。 另外,如果沒有這裏的信息,我將無法解決這個問題How come some controls don't have a windows handle?。
