vb.net自动发送多条 vb发送按键( 二 )

IT技术执行


shell "cmd /c dirpause",1'多条语句可用连接
关于cmd的具体用法可以在命令提示符下敲入cmd/?看看
太多了，只列举一些典型的：
CMD [/A | /U] [/Q] [/D] [/E:ON | /E:OFF] [/F:ON | /F:OFF] [/V:ON | /V:OFF]
[[/S] [/C | /K] string]
/C执行字符串指定的命令然后终断
/K执行字符串指定的命令但保留
/S在 /C 或 /K 后修改字符串处理(见下)
/Q关闭回应
/D从注册表中停用执行 AutoRun 命令(见下)
/A使向内部管道或文件命令的输出成为 ANSI
【vb.net自动发送多条 vb发送按键】/U使向内部管道或文件命令的输出成为 Unicode
/T:fg设置前景/背景颜色(详细信息 ， 请见 COLOR /?)
/E:ON启用命令扩展(见下)
/E:OFF停用命令扩展(见下)
/F:ON启用文件和目录名称完成字符 (见下)
/F:OFF停用文件和目录名称完成字符(见下)
/V:ON将 ! 作为定界符启动延缓环境变量扩展 。如: /V:ON 会
允许 !var! 在执行时允许 !var! 扩展变量 var 。var 语法
在输入时扩展变量 ， 这与在一个 FOR 循环内不同 。
/V:OFF停用延缓的环境扩展 。
VB.net 怎么制作按键连发功能用API函数，以下代码Private Declare Function GetWindowLong Lib "user32" Alias "GetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long) As LongPrivate Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" (ByVal hwnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long
Private Declare Function SetLayeredWindowAttributes Lib "user32" (ByVal hwnd As Long, ByVal crKey As Long, ByVal bAlpha As Byte, ByVal dwFlags As Long) As LongPrivate Const WS_EX_LAYERED = H80000
Private Const GWL_EXSTYLE = (-20)
Private Const LWA_ALPHA = H2
Private Const LWA_COLORKEY = H1Private Declare Function SetWindowPos Lib "user32" (ByVal hwnd As Long, ByVal hWndInsertAfter As Long, ByVal X As Long, ByVal Y As Long, ByVal cx As Long, ByVal cy As Long, ByVal wFlags As Long) As Long
Private Const HWND_TOPMosT = -1
Private Const SWP_NOMOVE = H2
Private Const SWP_NosIZE = H1
Private Declare Function GetForegroundWindow Lib "user32" () As Long
Private Declare Function PostMessage Lib "user32" Alias "PostMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Const WM_KEYDOWN = H100
Const WM_KEYUP = H101
Const WM_CHAR = H102
Const VK_F1 = H70
Private Sub SendF1(hwnd)'调用这个过程即可对目标窗体发送F1键
Call PostMessage(hwnd, WM_KEYDOWN, VK_F1, 0)
Call PostMessage(hwnd, WM_KEYUP, VK_F1, 0)
End Sub这里是发送F1的实例，各个按键对应的虚拟键码，要到网上查
