- dll 注入后可自动弹出窗口,但键盘钩子无法呼出窗口
- 这看起来很简单的问题难倒多少高手??? windows.SetParent(form2.Handle, form1.Handle);
- 在线程里打开EXCEL怎么关闭呀
- 感谢帮助过我的各位大哥~散分(今天揭贴)
- 为什么备份可用,恢复不起作用?(50分在线等)
- 自己定义的类的运算符重载的申明怎么写的?
- 数据库表的备份与恢复
- 什么Delphi杂志比较好?
- 求助???
- 各位,如果<<Delphi4从入门到精通>>可以得80分,那哪本书可得100分
- 用过DLL的请进(续),欢迎讨论
- 如果没有安装SQLSERVER数据库段,而只是安装MSDE的话,是不是能够操作SQL数据库?
然后调用这个pas文件
