I need this program to check if something doesn't exist, then copy itself to that location, The copy part works fine, but I keep getting an error on launch: Object required "

Option Explicit

Dim objShell, strCmd, strTargetFolder, objFSO, strFile, strDirectory

'Copy to startup section =====
strDirectory = "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup"

strFile = strDirectory & "\wippre-alpha.vbs"

If Not objFSO.FileExists(strFile) Then

strTargetFolder = "C:\Users\Arion\Documents\Environment\Test"

Set objShell = CreateObject("WScript.Shell")

strCmd = "%comspec% /c copy """ & WScript.ScriptFullName & """ """ & strTargetFolder & """ /Y"
objShell.Run strCmd
End if

Correct. You don't instanciate objFSO.

Set objFSO = CreateObject("Scripting.FileSystemObject")

Open in new window


See also Accessing Files with FileSystemObject.

E.g.

Option Explicit

Dim objShell, strCmd, strTargetFolder, objFSO, strFile, strDirectory

strDirectory = "C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup"
strFile = strDirectory & "\wippre-alpha.vbs"
strTargetFolder = "C:\Users\Arion\Documents\Environment\Test"
strCmd = "%comspec% /c copy """ & WScript.ScriptFullName & """ """ & strTargetFolder & """ /Y"

Set objFSO = CreateObject("Scripting.FileSystemObject"
If Not objFSO.FileExists(strFile) Then
  Set objShell = CreateObject("WScript.Shell")  
  objShell.Run strCmd
  Set objShell = Nothing
End if 

Set objFSO = Nothing

Open in new window


btw, why don't you use File.Copy of FileSystemObject instead of the command line?

Don't you want the file to end up in this folder, not the target folder?

C:\ProgramData\Microsoft\Windows\Start Menu\Programs\Startup

Also, is the script that this code will be in named wippre-alpha.vbs, or something else?  If that is the name then no need to append it to strFile, you can just use the directory as the destination of the copy.

Copy can't be done by file system object because in the prior question it was stated that the running VBS script was the file that needed to be copied ("copy itself"), and you can't do that with file system object, it throws an access denied error.

with

Option Explicit

WScript.Echo "CopyMe"
FileCopyIfNotExists "C:\Temp\Fldr1\CopyMe.vbs", "C:\Temp\Fldr2\I'm a Hero!.vbs"
WScript.Echo "Done."
WScript.Echo

Public Function FileCopyIfNotExists(ASource, ADestination)

  On Error Resume Next

  Dim fso, f

  Set fso = CreateObject("Scripting.FileSystemObject")
  If Not fso.FileExists(ADestination) Then
    Set f = fso.GetFile(ASource)
    f.Copy(ADestination)    
	If Err.Number <> 0 Then
	  WScript.Echo "D'oh: " & Err.Description
	End If
	
	Set f = Nothing
  End if 

  Set fso = Nothing

End Function

Cleaned version:

Option Explicit

Dim objShell, strCmd, strTargetFolder, objFSO, strFile, 

'Copy to startup section =====

Set objFSO = CreateObject("Scripting.FileSystemObject")

If Not objFSO.FileExists(strFile) Then

strTargetFolder = "C:\Users\Arion\Documents\Environment\Test"

Set objShell = CreateObject("WScript.Shell")

strCmd = "%comspec% /c copy """ & WScript.ScriptFullName & """ """ & strTargetFolder & """ /Y"
objShell.Run strCmd
End if
