SendKeys With VBScript

0

Example

‘VBScript Example
Set WshShell = WScript.CreateObject(“WScript.Shell”)

WshShell.Run “%windir%\notepad.exe”
WshShell.AppActivate “Notepad”

WshShell.SendKeys “Hello World!”
WshShell.SendKeys “{ENTER}”
WshShell.SendKeys “abc”
WshShell.SendKeys “{CAPSLOCK}”
WshShell.SendKeys “def”

The SendKeys method is used to send keystrokes to the currently active window as if they where typed from the keyboard.

WshShell.SendKeys Keystrokes

Single alphanumeric keystrokes can simply be specified using a string representation of the character required. For example, to send the letter S the command would be object.SendKeys “S”.

To send multiple characters combine them into one string. For example, to send A, B and C the command would be object.SendKeys “ABC”.

The plus sign “+”, caret “^”, percent sign “%”, tilde “~”, and parentheses “()” all have special meanings and must be enclosed within braces “{}”. Square brackets “[]” must also be enclosed within braces although they have no special meaning. To specify brace characters themselves, use “{{}” and “{}}”.

Below is a table of characters that can not be directly represent by a keyboard character to use one of these, specify the appropriate Code.

Key Code

Key Code
Backspace {BACKSPACE}, {BKSP} or {BS}
Break {BREAK}
Caps Lock {CAPSLOCK}
Delete {DELETE} or {DEL}
Down Arrow {DOWN}
End {END}
Enter {ENTER} or ~
Escape {ESC}
Help {HELP}
Home {HOME}
Insert {INSERT} or {INS}
Left Arrow {LEFT}
Num Lock {NUMLOCK}
Page Down {PGDN}
Page Up {PGUP}
Print Screen {PRTSC}
Right Arrow {RIGHT}
Scroll Lock {SCROLLLOCK}
Tab {TAB}
Up Arrow {UP}
F1 {F1}
F2 {F2}
F3 {F3}
F4 {F4}
F5 {F5}
F6 {F6}
F7 {F7}
F8 {F8}
F9 {F9}
F10 {F10}
F11 {F11}
F12 {F12}
F13 {F13}
F14 {F14}
F15 {F15}
F16 {F16}

 

To specify characters combinations use the following codes:

 

Key Code
Alt %
Ctrl ^
Shift Lock +

For example to specify CTRL and C, the code would be object.SendKeys “^C” and for SHIFT F5 object.SendKeys “+{F5}”. To specify multiple combination sets such as ALT A Z, you use parentheses, for example, object.SendKeys “%(AZ)”.

VBScript – Find and replace text in text file

1
VBS has a great function - replace. Next VBS script lets you replace string  in a text file. Replace works with text compare (case insensitive). Use: 
[cscript|wscript] replace.vbs Find Replacewith File

Find … Required. Substring being searched for.
Replacewith … Required. Replacement substring.
File … Source and destination file for the replacement

Dim FileName, Find, ReplaceWith, FileContents, dFileContents
Find         = WScript.Arguments(0)
ReplaceWith  = WScript.Arguments(1)
FileName     = WScript.Arguments(2)

'Read source text file
FileContents = GetFile(FileName)

'replace all string In the source file
dFileContents = replace(FileContents, Find, ReplaceWith, 1, -1, 1)

'Compare source And result
if dFileContents <> FileContents Then
  'write result If different
  WriteFile FileName, dFileContents

  Wscript.Echo "Replace done."
  If Len(ReplaceWith) <> Len(Find) Then 'Can we count n of replacements?
    Wscript.Echo _
    ( (Len(dFileContents) - Len(FileContents)) / (Len(ReplaceWith)-Len(Find)) ) & _
    " replacements."
  End If
Else
  Wscript.Echo "Searched string Not In the source file"
End If

'Read text file
function GetFile(FileName)
  If FileName<>"" Then
    Dim FS, FileStream
    Set FS = CreateObject("Scripting.FileSystemObject")
      on error resume Next
      Set FileStream = FS.OpenTextFile(FileName)
      GetFile = FileStream.ReadAll
  End If
End Function

'Write string As a text file.
function WriteFile(FileName, Contents)
  Dim OutStream, FS

  on error resume Next
  Set FS = CreateObject("Scripting.FileSystemObject")
    Set OutStream = FS.OpenTextFile(FileName, 2, True)
    OutStream.Write Contents
End Function

VBScript – Disconnecting Network Drive and Reconnecting with User Name in the Path of the Network Drive.

0
The below VBScript will get the current user that is logged into the computer, then disconnect and reconnect a failed network drive.  In this case the user name is a part of the path to the user’s personal drive, \\spksan\users\davidh\ for example.  It then displays a pop up stating that it’s done.
On Error Resume Next
userName = “”
strComputer = “.”
Set objWMIService = GetObject(“winmgmts:\\” & strComputer & “\root\cimv2”)
Set colItems = objWMIService.ExecQuery(“Select * from Win32_ComputerSystem”,,48)
For Each objItem in colItems
userName = objItem.UserName
If InStr(objItem.UserName, “\”) Then
userNameArray = Split(objItem.UserName, “\”)
userNameCounter = 0
For Each userNames In userNameArray
If userNameCounter = 1 Then
userName = userNames
End If
userNameCounter = userNameCounter + 1
Next
End If
Next
Set objItem = Nothing: Set colItems = Nothing: Set objWMIService = Nothing
If Not userName = “” Then
Set objShell = CreateObject(“WScript.Shell”)
Set objNetwork = CreateObject(“WScript.Network”)
objNetwork.MapNetworkDrive “U:”, “\\spksan\users\” & userName
If Err.Number <> 0 Then
objNetwork.RemoveNetworkDrive  “U:”, true
WScript.Sleep 10000
objNetwork.MapNetworkDrive “U:”, “\\spksan\users\” & userName
End If
End If
WScript.Echo “Done fixing U Drive”
