我想在windows中的任何地方 按下F1 就自動送出"1234"和滑鼠左鍵一下? 看了一些文章 知道要使用dll 和hook 但是一直沒頭緒 各位大大能否給個 例子 ??謝謝

How can I create a system wide keyboard hook under Win32: http://www.delphifaq.com/fq/q2108.shtml

小弟不材 可否舉個例子 這個dll該如何使用?

那參考這篇吧, 有詳細的步驟: http://oldlook.experts-exchange.com/Programming/Programming_Languages/Delphi/Q_20694870.html --- Everything I say is a lie. @>---
