VBS script error - "Expected Statement" - checked for errors - vbscript

I'm new so please forgive me if I'm wrong. I'm using this code here where I am getting a
Expected Statement - Line 3 Char 1
Code:
Set wshShell =wscript.CreateObject("WScript.Shell")
dowscript.sleep100wshShell.sendkeys
"{CAPSLOCK}"wshshell.sendkeys
"{NUMLOCK}"wshshell.sendkeys "{SCROLLLOCK}"
loop
Any ideas?
EDIT: When trying to put that code within an existing loop like below I get invalid charecter line 1 char 1
Set oWMP = CreateObject("WMPlayer.OCX.7" )
Set colCDROMs = oWMP.cdromCollection
if colCDROMs.Count >= 1 then
do
For i = 0 to colCDROMs.Count - 1
colCDROMs.Item(i).Eject
Next ' cdrom
For i = 0 to colCDROMs.Count - 1
colCDROMs.Item(i).Eject
Next ' cdrom
loop
End If
Set wshShell = WScript.CreateObject("WScript.Shell")
Do
WScript.Sleep 100
wshShell.Sendkeys "{CAPSLOCK}"
wshshell.Sendkeys "{NUMLOCK}"
wshshell.Sendkeys "{SCROLLLOCK}"

Not sure where you copied this from, but it's lost spaces and line breaks, which is why you get the error
Expected Statement - Line 3 Char 1
when executing it. The code should read;
Set wshShell = WScript.CreateObject("WScript.Shell")
Do
WScript.Sleep 100
wshShell.Sendkeys "{CAPSLOCK}"
wshshell.Sendkeys "{NUMLOCK}"
wshshell.Sendkeys "{SCROLLLOCK}"
Loop
It's a fairly basic script that loops forever with a 100 millisecond wait (to stop the machine from completely freezing as the OS battles with the script) and sends the key sequence CAPSLOCK, NUMLOCK and SCROLLLOCK. To me, it just looks like a prank script designed to flash the LED key indicators on most standard QWERTY keyboards in sequence, over and over.
It's worth noting VBScripts in general are not designed to run forever and writing infinite loops like this one can have varying results.

VBScript loops in section of sub that does not contain looping code

Windows 10 Enterprise
Version 20H2
I am writing a VBScript that handles a print to PDF dialogue window.
The goal:
Detect that the printer dialogue window is open (using a loop that continuously checks)
If/when detected, handle the dialogue (send the filename, send the file path, click "print" to finish)
The problem: for some reason, the sub endlessly loops through an If statement. I don't understand why the code is looping through a section containing no loop code.
The code basically sends the same keys in a loop over and over again within the dialogue window, never completing the If statement.
As a small aside, I think the sendKeys command I use to close the dialogue is incorrect, but that should not cause an IF statement to loop.
Code (go to the section indicated by "#"'s to see where I am having issues):
Sub handlePrintDial()
iSeconds = 20
'================================================================================
' Set time variables
'================================================================================
tNow = now()
tFuture = DateAdd("s",iSeconds,tNow)
'================================================================================
' Set other objects
'================================================================================
Set WshShell = CreateObject("WScript.Shell")
sApp = "Save Print Output As"
sFileName = "This is a test-" & Year(now()) & Month(now()) & Day(now()) & Hour(now()) & Minute(now()) & Second(now())
'================================================================================
' Loop until window opens or time elapses
'================================================================================
Do Until Now() > tFuture
ret = WshShell.AppActivate(sApp)
If ret = True Then
Exit Do
End If
Loop
If ret <> True Then
MsgBox "Printer window not found. Please try again."
Exit Sub
End If
'================================================================================
' If printer window detected, handle window
'================================================================================
WScript.Sleep 500
ret = WshShell.AppActivate(sApp)
'########This is the top of the endless loop####################
If ret = True Then
ret = wshShell.AppActivate(sApp)
' Send filename
WScript.Sleep 2000
wshShell.sendKeys sFileName
WScript.Sleep 2000
' Send file path to save to
wshShell.sendKeys "{F4}"
WScript.Sleep 2000
wshShell.sendKeys "{BS}"
WScript.Sleep 2000
wshShell.sendKeys "^A"
WScript.Sleep 2000
wshShell.sendKeys "{del}"
WScript.Sleep 2000
wshShell.sendKeys "C:\Users\Username\Desktop\closeDialogue.vbs"
WScript.Sleep 2000
' "Click" print to complete the dialogue window
wshShell.sendKeys "{enter}"
WScript.Sleep 2000
wshShell.sendKeys "{enter}"
WScript.Sleep 2000
End If
WScript.Sleep 500
'########This is the bottom of the endless loop####################
WScript.Quit
End Sub
Call handlePrintDial()
Here is the window I am trying to handle:
After some experimentation, I discovered that the sendKeys "{enter}" commands were mysteriously causing the script to execute again (two simultaneous instances of the code running at once, per command line). When I removed Enter keys, the code ran normally without kicking off new instances of the script.
Summary: use sendKeys at your own peril. Specifically, it appears {enter} can cause the code to have unusual problems.

VBScript not working when PC is locked

I'm running a VBScript that communicates to an exe file in Windows 7.
The VBScript works great!
The issues I have, is that once the PC has been in locked, goes to sleep or hiberation the VBScript doesn't communicate with the exe application.
The VBScript is running (I have a log that tells me every time a loop is complete, but its not communicating to the exe.
Below is code that is not working when the PC is locked.
Set WSHShell = WScript.CreateObject("WScript.Shell")
' info for exporting data
Const ForReading = 1, ForWriting = 2, ForAppending = 8
Const TristateUseDefault = -2, TristateTrue = -1, TristateFalse = 0
Dim fso, MyFile, FileName, TextLine, cycles
Dim I
I = 0
Dim n
n = .1 'how often the program saves the data (in minutes)
cycles = 2 'how many times it will save
FileName = "C:\Users\Desktop\new.txt" 'location where the log file will save
Dim sl
sl = n * 60000 'change from seconds to ms for the sleep function
Set fso = CreateObject("Scripting.FileSystemObject")
' Open the file for output
Set MyFile = fso.OpenTextFile(FileName, ForAppending, True, TristateTrue)
' Write to the file.
MyFile.WriteLine "Log file for recording data from Yokogawa MX100 (" & cycles
& " cycles)"
WSHShell.Run "MXStandardE.exe"
WScript.Sleep 1000
WSHShell.AppActivate "MXStandardE.exe"
WScript.Sleep 1000
Do while I < cycles
a = Now()
WScript.Sleep 1000
WSHShell.Run "MXStandardE.exe"
WScript.Sleep 1000
WSHShell.AppActivate "MXStandardE.exe"
WScript.Sleep 1000
WSHShell.SendKeys "%A"
WScript.Sleep 1000
WSHShell.SendKeys "{DOWN}"
WScript.Sleep 1000
WSHShell.SendKeys "{ENTER}"
I = I + 1
MyFile.Writeline I & " of " & cycles & " at " & a & " --time of each cycle is
" & n & " minutes"
WScript.Sleep sl 'when sl is used loop time is in minutes
Loop
MyFile.Close
MsgBox ("Script has completed")
As Ansgar already said, it's pretty obvious that nothing will work while the PC sleeps or hibernates. In the case where the PC is locked, techniques that rely on window management or direct input such as SendKeys won't work as expected, because the user's session, along with user-level applications, is essentially shelved to make way for the login screen or another user.
You might want to do some research into the SendMessage/PostMessage API, or you can stop using VBScript and replace it with a Scheduled Task or system service that runs using a local service account, assuming you just want to execute an exe without any UI interaction.
The question is: do you need to go under hibernation or pc suspension? If not, you should simply configure or turn off those settings. By only locking the session, the vbscript should be run and generate an outpout without any trouble. By checking and configuring advanced windows energy settings it might help you solving this.

How can I end a Do Loop after some sort of user input?

Any kind of user input will do. Here's the code I have so far.
Set WshShell = WScript.CreateObject("WScript.Shell")
Dim Account
Account = 111111
WScript.Sleep 5000
Do
WScript.Sleep 400
WshShell.SendKeys "drill "
WshShell.SendKeys Account
WshShell.SendKeys "{ENTER}"
Account = Account + 1
Loop
Basically it's a code guesser (for a game) and I want to be able to interrupt it with any kind of user input.
I don't think we have any direct solution. Below code seeks for user interaction after 50 iterations. If yes, control exits from do loop. You can play around with other ways to interrupt the loop and of course you can change the counter as per your need.
Set WshShell = WScript.CreateObject("WScript.Shell")
Dim counter
Dim Account
Dim msgResult
counter = 0
Account = 111111
WScript.Sleep 5000
Do
WScript.Sleep 400
WshShell.SendKeys "drill "
WshShell.SendKeys "drill "
WshShell.SendKeys Account
WshShell.SendKeys "{ENTER}"
Account = Account + 1
If counter = 50 Then 'get user input after 50 iterations
msgResult = MsgBox("Do you want to exit?", vbYesNo)
If msgResult = vbYes Then 'if yes
Exit Do
End If
End If
counter = counter + 1
If counter > 101 then
counter =0
End If
Loop

VB script on Cisco Anyconnect VPN

I am new to use VB script. I am using the below code to connect my VPN. But the problem is that after entering "select" button in VPN client, the second page display is depending on Network Speed. Sometimes it is loaded within 4 sec, sometimes after 10 sec. Is there any code where i can get the VPN is fully loaded or not (like BUSY command for IE).
set WshShell=Wscript.CreateObject("Wscript.Shell")
WshShell.Run("""C:\\Program Files\Cisco\Anyconnect\vpnui.exe""")
WScript.Sleep 500
WshShell.SendKeys "{ENTER}"
WScript.Sleep 500
WshShell.SendKeys "username"
WshShell.SendKeys "rsa_no"
WshShell.SendKeys "password"
WScript.Sleep 500
WshShell.SendKeys "{ENTER}"
Whilst not vb script, I think this approach should still work.
I have the vpncli directory in my %path%
I have a batch file:
vpncli.exe connect xyz.123.com -s < d:\vpncreds.txt
with the credentials in a separate file (d:\vpncreds.txt):
username
password
y
Note: you need an empty line at the end.
This works fine here, and wonder if you take the credentials out of your VB script and put them in a separate file, it might achieve what you need to.
Also, if your credentials change, you only need to change the one file, and not the potential handful of script files if you access the vpn in multiple scripts.
Try my code below. Note that you may have to adjust sleep times (in milliseconds). To see what's happening in the command prompt, change the 2 in the 9th line to a 1.
Dim host, username, password, pathToClient
host = "yourHostURL"
username = "yourUsername"
password = "yourPassword"
pathToClient = "C:\Program Files {(}x86{)}\Cisco\Cisco AnyConnect Secure Mobility Client\vpncli.exe"
Set ws = WScript.CreateObject("WScript.Shell")
ws.run("TASKKILL.exe /F /IM vpnui.exe"), 0, false
ws.run("cmd.exe"), 2, false
ws.AppActivate("Command Prompt")
WScript.Sleep 300
ws.SendKeys """" & pathToClient & """ connect " & host & "~"
WScript.Sleep 1000
ws.SendKeys(username & "~")
WScript.Sleep 50
ws.SendKeys(password & "~")
ws.run("TASKKILL.exe /F /IM cmd.exe"), 0, false
Here is an improved version that doesn't wait for sleep timeouts, i.e. connects as soon as the window becomes visible. This works with the latest version of AnyConnect (4.10 as of writing).
' Script to automatically connect to Cisco AnyConnect.
' This script assumes that you have already set up your connection.
Const Password = "[YOUR PASSWORD]" ' Enter your password here
Const ConnectionUrl = "[YOUR CONNECTION URL]" ' Enter the URL of your endpoint (without HTTP prefix)
' Copy password to clipboard in case something goes wrong (to connect manually)
CopyToClipboard(Password)
Set WshShell = WScript.CreateObject("WScript.Shell")
WshShell.Run """%PROGRAMFILES(x86)%\Cisco\Cisco AnyConnect Secure Mobility Client\vpnui.exe"""
ActivateWindow("Cisco AnyConnect Secure Mobility Client")
WshShell.SendKeys "{ENTER}"
ActivateWindow("Cisco AnyConnect | " + ConnectionUrl)
WshShell.SendKeys "{TAB}"
WshShell.SendKeys Password
WshShell.SendKeys "{ENTER}"
Function ActivateWindow(title)
Const Step = 100
Const Timeout = 10000
Dim Result
Dim Counter
For Counter = 0 To Timeout Step Step
Result = WshShell.AppActivate(title)
If Result Then Exit For
WScript.Sleep Step
Next
If Result = False Then
MsgBox("Window '" + title + "' not found.")
WScript.Quit
End If
End Function
Function CopyToClipboard(Input)
If IsNull(Input) Then
Set Clipboard = CreateObject("HTMLFile").parentWindow.clipboardData.getData("Text")
If IsNull(Clipboard) Then Clipboard = ""
Else
CreateObject("WScript.Shell").Run _
"mshta.exe javascript:eval(""document.parentWindow.clipboardData.setData('text','" _
& Replace(Replace(Replace(Input, "'", "\\u0027"), """","\\u0022"),Chr(13),"\\r\\n") & "');window.close()"")", _
0,True
End If
End Function

VBScript - Error 0x80041017 (null)

IMPORTANT UPDATE:
As Cheran S stated below, it's a good idea to avoid using "taskmgr" for this script. I'm not going to edit the code, as I feel it's best to maintain the original question as much as possible since doing so would partially invalidate & obfuscate Cheran's answer & comment.
A good alternative to "taskmgr" would be "CharMap" (for simple & fast testing).
Running Windows XP Professional (32-bit) and I've got this script that's throwing up this error:

objWshShell.AppActivate(strWinTitle(intWinTitle))

End If
Set colProcesses = Nothing

End Sub
Call srBlockWindow(arrWinTitle, 0, arrProcName, 0)
I've reviewed this, but I believe my script doesn't have any issues with the quotes. For the sake of clarity, I'm getting the error at the start of the "For Each ..." string.
What's peculiar is that it will run fine the first time, but once it loops, that's when I get the error. So, it will close all the desired Windows/Applications, but once it goes through it's second iteration, I get the error. I've inserted "On Error Resume Next", but that doesn't resolve it (I will add it later, since it's required to resolve the conflict when the Window/Process Starts simultaneously with Close/End/Stop attempts made by the Script).
I think it's because I should be conditionally checking if the process exists; problem is, I'm not quite sure how to do that with this code (I've never been good with Collections). Anybody have suggestions on how to do it with this code specifically?
I reviewed this and tried to write a quick alternative script, but it didn't really work. Here's the code:
Set service = GetObject("winmgmts:")
Dim arrProcName(3)
arrProcName(0) = "'taskmgr.exe'"
arrProcName(1) = "'calc.exe'"
arrProcName(2) = "'notepad.exe'"
Sub srTest(strProc, intProc)
i = 0
Do While i = 0
For Each Process In Service.InstancesOf("Win32_Process")
If Process.Name = strProc(intProc) Then
Process.Name.Terminate
Process.Terminate
End If
Next
If intProc = 0 Then
intProc = intProc + 1
ElseIf intProc >= 3 Then
intProc = 0
End If
Loop
End Sub
Call srTest(arrProcName, 0)
As you can see, I tried both "Process.Terminate" & "Process.Name.Terminate", but neither yielded anything (not even an error). I further tested it with "Wscript.Echo Process.Name" & "Wscript.Echo strProc(intProc)", but neither of these worked too.
Now that I've failed at this alternative solution, I'm feeling that I'm wildly stabbing in the dark for solutions, so I'll defer these esoteric challenges to the community that is vastly superior to me.
There might be a few here who are reading this and wondering why I'm targeting My Documents, Control Panel, taskmgr.exe, calc.exe, & notepad.exe. Almost everybody reading this will probably be able to extrapolate on their own, but I'll make sure I'm clear on this for those who need it. I'm doing this because it makes it easier to test, since all of these can be accessed simply by using the "Run" shortcut (Windows Key + R) & then entering the following strings (one at a time, of course):
My Documents
Control
taskmgr
calc
notepad
You likely knew the keywords, but I just wanted to highlight why I'm using these specific ones (speed & simplicity).
I'll remove this if Cheran adds the final code to the answer posted
Final Solution:
Set objWshShell = Wscript.CreateObject("Wscript.Shell")
Set objWshNet = CreateObject("Wscript.Network")
strComputer = objWshNet.ComputerName
Set objWMIService = GetObject("winmgmts:" & _
"{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Dim arrWinTitle
arrWinTitle = Array("My Documents", "Control Panel")
Dim arrProcName
arrProcName = Array("'charmap.exe'", "'calc.exe'", "'notepad.exe'")
Sub srBlockWindow(strWinTitle, intWinTitle, strProcName, intProcName)
i = 0
Do While i = 0
On Error Resume Next
' In the Event of Conflict w/Initiation of Window or Process
If objWshShell.AppActivate(strWinTitle(intWinTitle)) Then
objWshShell.AppActivate(strWinTitle(intWinTitle))
Wscript.Sleep 100
objWshShell.SendKeys "%{F4}"
Wscript.Sleep 100
End If
intWinTitle = (intWinTitle + 1) Mod (UBound(strWinTitle) + 1)
Wscript.Sleep 100
Set colProcesses = objWMIService.ExecQuery _
("SELECT * FROM Win32_Process WHERE NAME = " & strProcName(intProcName))
For Each objProcess In colProcesses
objProcess.Terminate()
Next
intProcName = (intProcName + 1) Mod (UBound(strProcName) + 1)
Set colProcesses = Nothing
Loop
End Sub
Call srBlockWindow(arrWinTitle, 0, arrProcName, 0)
Here's a quick script I threw together to test it against:
Set objWshShell = Wscript.CreateObject("Wscript.Shell")
i = 0
Do While i = 0
objWshShell.Run "explorer.exe /e, C:\Documents and Settings\User\My Documents"
Wscript.Sleep 200
objWshShell.Run "CharMap.exe"
Wscript.Sleep 200
objWshShell.Run "Control.exe"
Wscript.Sleep 200
objWshShell.Run "calc.exe"
Wscript.Sleep 200
objWshShell.Run "notepad.exe"
Wscript.Sleep 200
Loop
BE CAREFUL! Adjust the timings so that you can end "Wscript.exe" without too many problems. Best to run both scripts simultaneously to see how it works.
Two big issues I found:
The main problem here is in the way you define your arrays. The number you specify in the array declaration is the largest array subscript. Since VBScript arrays are always indexed starting at 0, you actually need to specify one less than the number of elements in the array.
' This is wrong:
Dim arrWinTitle(2)
Dim arrProcName(3)
' Should be:
Dim arrWinTitle(1)
Dim arrProcName(2)
You could also use the Array function to initialize your array, assuming that you know beforehand how many elements are in it. In that case, you would just declare arrWinTitle as a Variant and not as an array:
Dim arrWinTitle
arrWinTitle = Array("My Documents", "Control Panel")
If you make that change and try to run the script, you'll still get a "Subscript out of range" error. That error is caused by this block:
If intProcName >= 0 Then
intProcName = intProcName + 1
ElseIf intProcName >= 5 Then
intProcName = 0
End If
First off, the maximum subscript should be 2 for strProcName, and not 5. Even then, this code won't work. It seems like what you're trying to do is loop through the elements of array, then start over back at 0. A better of doing this is with the Mod operator:
intProcName = (intProcName + 1) Mod (UBound(strProcName) + 1)
Notice also how I use the UBound function to avoid hard-coding the actual length of the array.
I won't spend too much time analyzing your second example, since it was just an attempt to make the first example work. I will note, however, that in your arrProcName array, the process names still have the single quotes around them, which is one reason why that script didn't work either.
