Executing VBScript file from Excel VBA macros - vbscript

Question

I need some excel vba examples, where with in the VBA code(Excel Macro) i could call a VBScript and will get some values like filename and directory information from the vbscript and assign it to the variables in VBA code.
Thank you in advance
Some thing like this
VBA macro:
Sub Foo2Script
Dim x As Long
x=2
'Call VBscript here
MsgBox scriptresult
End Sub
VBScript:
Dim x, y ,Z
x = x_from_macro
y = x + 2
Z = X+Y
scriptresult = y,Z

It can be done but I would have to agree with Tomalak and others that it's not the best way to go. However, saying that, VBScript can work wonders occasionally if you use it as a kind of fire and forget mechanism. It can be used quite effectively to simulate multi-threading in VBA whereby you breakdown the payload and farm it out to individual VBScripts to run independently. Eg you could arrange a "swarm" of individual VBScripts to mass download from websites in the background whilst VBA continues with other code.
Below is some VBA code I've simplified to show what can be done and writes a simple VBScript on the fly. Normally I prefer to run it using 'wshShell.Run """" & SFilename & """" which means I can forget about it but I've included in this example this method Set proc = wshShell.exec(strexec) which allows a test of the object for completion
Put this in MODULE1
Option Explicit
Public path As String
Sub writeVBScript()
Dim s As String, SFilename As String
Dim intFileNum As Integer, wshShell As Object, proc As Object
Dim test1 As String
Dim test2 As String
test1 = "VBScriptMsg - Test1 is this variable"
test2 = "VBScriptMsg - Test2 is that variable"
'write VBScript (Writes to Excel Sheet1!A1 & Calls Function Module1.ReturnVBScript)
s = s & "Set objExcel = GetObject( , ""Excel.Application"") " & vbCrLf
s = s & "Set objWorkbook = objExcel.Workbooks(""" & ThisWorkbook.Name & """)" & vbCrLf
s = s & "Set oShell = CreateObject(""WScript.Shell"")" & vbCrLf
s = s & "Msgbox (""" & test1 & """)" & vbCrLf
s = s & "Msgbox (""" & test2 & """)" & vbCrLf
s = s & "Set oFSO = CreateObject(""Scripting.FileSystemObject"")" & vbCrLf
s = s & "oShell.CurrentDirectory = oFSO.GetParentFolderName(Wscript.ScriptFullName)" & vbCrLf
s = s & "objWorkbook.sheets(""Sheet1"").Range(""" & "A1" & """) = oShell.CurrentDirectory" & vbCrLf
s = s & "Set objWMI = objWorkbook.Application.Run(""Module1.ReturnVBScript"", """" & oShell.CurrentDirectory & """") " & vbCrLf
s = s & "msgbox(""VBScriptMsg - "" & oShell.CurrentDirectory)" & vbCrLf
Debug.Print s
' Write VBScript file to disk
SFilename = ActiveWorkbook.path & "\TestVBScript.vbs"
intFileNum = FreeFile
Open SFilename For Output As intFileNum
Print #intFileNum, s
Close intFileNum
DoEvents
' Run VBScript file
Set wshShell = CreateObject("Wscript.Shell")
Set proc = wshShell.exec("cscript " & SFilename & "") ' run VBScript
'could also send some variable
'Set proc = wsh.Exec("cscript VBScript.vbs var1 var2") 'run VBScript passing variables
'Wait for script to end
Do While proc.Status = 0
DoEvents
Loop
MsgBox ("This is in Excel: " & Sheet1.Range("A1"))
MsgBox ("This passed from VBScript: " & path)
'wshShell.Run """" & SFilename & """"
Kill ActiveWorkbook.path & "\TestVBScript.vbs"
End Sub
Public Function ReturnVBScript(strText As String)
path = strText
End Function
This demonstrated several ways that variables can be passed around.
