VB 中使用SendKeys开启Run 窗口和是用API函数去开启Run

在使用Shell 去调用一个可执行文件是，居然开启程式后自动关闭，不得不寻找其它的方法去解决。

1.使用SendKeys开启Win键，再送键”R”,开启“运行”，等待100us,给运行窗口送一串字符，回车。

OptionExplicit

PrivateDeclare Sub keybd_event Lib "user32.dll" (ByVal bVk As Byte,ByValbScan As Byte,ByVal dwFlags As Long,ByVal dwExtraInfo As Long)

PrivateDeclare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)

Private Const KEYEVENTF_KEYUP = &H2

Private Const KEYEVENTF_EXTENDEDKEY = &H1

Private Const VK_LWIN = &H5B'左WIN键

Private Const VK_RWIN = &H5C'右WIN键

PrivateSub Form_Load()

keybd_eventVK_LWIN,KEYEVENTF_EXTENDEDKEY,0 ' 按下

keybd_event VK_LWIN,KEYEVENTF_KEYUP,0 ' 弹起

Sleep (50)

SendKeys "r",True

Sleep (50)

SendKeys "\\192.168.2.42",True

'此例是登入服务网络，可以使用其它的可执行文件，例如"C:\Program Files\Google\Chrome\Application\chrome.exe"

Sleep (50)

SendKeys"{ENTER}"

End Sub

2.使用句柄

’开启运行窗口

Dim objshell
Set objshell = CreateObject("shell.application")
objshell.filerun
Delaytime (1000)
lRunHwnd = FindWindow(vbNullString,"运行")

，查找到运行窗口的句柄
While lRunHwnd = 0
Delaytime (100)
lRunHwnd = FindWindow(vbNullString,"运行")
Debug.Print lRunHwnd
Wend

‘查找到运行窗口的组合框
lComBOHwnd = findwindowex(lRunHwnd,"ComboBox",vbNullString)
lTxtHwnd = findwindowex(lComBOHwnd,"Edit",vbNullString)

’给TEXT文本框传递字符串，即要执行的程式及路径 SendMessage lTxtHwnd,WM_SETTEXT,255,ByVal "C:\Program Files\Intel Corporation\Intel(R) Thermal Analysis Tool\tat.exe" lCmdHwnd = findwindowex(lRunHwnd,vbNullString,"确定") SendMessage lCmdHwnd,WM_LBUTTONDOWN,ByVal 0&,ByVal 0& SendMessage lCmdHwnd,WM_LBUTTONUP,ByVal 0&
