vbscript+function calling function - return value - vbscript

Question

I have a vbscript that calls a second vbscript and runs a function. This second function returns a value. But I can't figure out how to get this value, as the result of the first function returns the status code.
original call: fileCASTRING(12345678)
vbscript 1
function fileCASTRING(varRAW)
lresult = CreateObject("WScript.Shell").Run ("c:\windows\syswow64\cscript.exe C:\ERMXData\Config\query-castring.vbs " & varRAW,0,true)
fileCASTRING=1
end function
query-castring.vbs
doctype=WScript.Arguments.Item(0)
Dim strCon
strCon = "DSN=*****; " & _
"uid=*****;pwd=*****;"
Dim oCon: Set oCon = WScript.CreateObject("ADODB.Connection")
Dim oRs: Set oRs = WScript.CreateObject("ADODB.Recordset")
oCon.Open strCon
Set oRs = oCon.Execute("select ESBLINK_ADMR_CODE from ESBLINK where ESBLINK_DTYP_CODE like '%" + doctype + "%'"")
queryB=oRs.Fields(0).Value
oCon.Close
Set oRs = Nothing
Set oCon = Nothing
I have to do it like this because the program that runs vbscript 1 runs in 64 bit mode and the code in query-castring.vbs needs to run in 32bit mode in order for it to work. How can I get the queryB value back to the original caller? I am trying to not have to write the value to a file.

The only easy way to communicate between two command line processes is via StdOut.
(Be aware the code is not tested but should get you into the right direction.)
VBScript 1
Option Explicit
' ...
Function fileCASTRING(varRAW)
Dim program, script, cmdline, output
program = "c:\windows\syswow64\cscript.exe /nologo"
script = "C:\ERMXData\Config\query-castring.vbs"
cmdLine = program & " " script & " """ & varRAW & """"
output = ""
With CreateObject("WScript.Shell").Exec(cmdLine)
While Not .StdOut.AtEndOfStream
output = output & .StdOut.ReadAll
Wend
End With
fileCASTRING = output
End Function
see the documentation of the WshScriptExec object
query-castring.vbs
Option Explicit
Dim doctype: doctype = WScript.Arguments.Item(0)
Dim strCon: strCon = "DSN=*****;uid=*****;pwd=*****;"
Dim strSql: "select ESBLINK_ADMR_CODE from ESBLINK where ESBLINK_DTYP_CODE like '%' + ? + '%'"
Dim oCon: Set oCon = WScript.CreateObject("ADODB.Connection")
Dim oCmd: Set oCmd = WScript.CreateObject("ADODB.Command")
oCon.Open strCon
With WScript.CreateObject("ADODB.Command")
Set .ActiveConnection = oCon
.CommandText = strSql
.Parameters.Add(.CreateParameter)
.Parameters(0).Value = doctype
With .Execute
If Not .EOF Then
WScript.Echo .Fields("ESBLINK_ADMR_CODE").Value
End If
End With
End With
oCon.Close
See the documentation of the ADODB Command and Parameter objects. Don't build SQL from strings.
Also, look into "integrated security" connection strings - do not store plain text passwords in in code files. ADODB can easily use the security context of the account that runs the script, if you tell it to.

VBScript 1
Function getADMRCODE(varRAW)
Dim program, script, cmdline, output
program = "c:\windows\syswow64\cscript.exe /nologo"
script = "C:\ERMXData\Config\common_app\queries\admrcode.vbs"
cmdLine = program & " " & script & " """ & varRAW & """"
output = ""
With CreateObject("WScript.Shell").Exec(cmdLine)
While Not .StdOut.AtEndOfStream
output = output & .StdOut.ReadAll
Wend
End With
getADMRCODE = output
End Function
query-castring.vbs
Dim doctype: doctype = WScript.Arguments.Item(0)
Dim strCon
strCon = "DSN=*****; " & _
"uid=*****;pwd=*****;"
Dim oCon: Set oCon = WScript.CreateObject("ADODB.Connection")
Dim oRs: Set oRs = WScript.CreateObject("ADODB.Recordset")
oCon.Open strCon
Set oRs = oCon.Execute("select ESBLINK_ADMR_CODE from ESBLINK where ESBLINK_DTYP_CODE LIKE '%" + doctype + "%'")
WScript.Echo oRs.Fields(0).Value
oCon.Close
Set oRs = Nothing
Set oCon = Nothing
