如何用VB编写一个向指定窗口发送键盘命令的程序？ 或者是向当前窗体发送键盘和鼠标命令的程序 ？ 谁知道怎么写啊 给点提示啊 谢谢了

Answer 1

用 Api函数 keybd_event

具体定义
Private Declare Sub keybd_event Lib "user32" Alias "keybd_event" (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long)

keybd_event 17, vbNull, &H2, vbNull

17 是要模拟的按键 17 是 ctrl 键
&H2模拟按键的动作 &H2是按下弹起

mouse_event 是模拟鼠标
具体庆扮定义
Private Declare Sub mouse_event Lib "李差族user32" Alias "mouse_event" (ByVal dwFlags As Long, ByVal dx As Long, ByVal dy As Long, ByVal cButtons As Long, ByVal dwExtraInfo As Long)

mouse_event &H2,vbnull,vbnull,vbnull,vbnull

&H2是要模拟的动作

移动鼠标 =&H1
模拟鼠标左键按下 =&H2
模拟鼠标左键抬起 =&H4
模拟鼠标右键抬起 =&H8
模拟鼠标右键按下 =&H10
模拟鼠标中键按下 =&H20
模拟鼠标哪弊中键抬起=&H40
