VBScript Error “Invalid or Unqualified Reference” with SendKeys Method

[jaredsmith9000]

I am getting the following error with my code in a .vbs file:

C:\...\Root_VBS_Script_1.vbs(19, 1) Microsoft

VBScript runtime error: Invalid or unqualified reference


1 was unexpected at this time.

The .vbs file is as follows:

Set wshShell = CreateObject("Wscript.Shell")


Set args = WScript.Arguments

arg1 = args.Item(0)


Dim filename


filename = ""&arg1&""



WshShell.SendKeys "root -b" //opens root in batch mode

WshShell.SendKeys "~"

WshShell.AppActivate ROOT_session

WshShell.SendKeys ".x analysis.C"

wshShell.SendKeys "~"

WshShell.SendKeys ".x double_gaus.C"

WshShell.SendKeys "~"

WshShell.AppActivate ROOT_session

WshShell.SendKeys "c1->SaveAs("&filename&.pdf&")"

WshShell.SendKeys "~"

WshShell.SendKeys ".q"

WshShell.SendKeys "~"


WScript.Quit 1

I am using the send keys method to run a program called root (developed by CERN) out of a .vbs file called from a batch file. I am attaching the filename as a parameter when calling the .vbs file. I am uncertain as to why I am getting this error, but I do know that the send keys method opens root and works up until it is supposed to save c1 as the given filename and type.

Can anyone help me resolve this error?

SaveAs("&filename&.pdf&")"

This is your problem perhaps it should be like this,

SaveAs(filename & ".pdf")
