Fetch all variable values in vbscript using msscript control


Is there any way to fetch all the variable values in the script at runtime.

Consider the following vbscript code.

var1= 5
Var2= 6

For i=0 To 5
   Msgbox i
Next

How do i Implement it using msscript control that i should be able to retrieve all the variables at runtime?

I am looking to implement a debugger for vbscript can i have the list of all the variables at runtime like below.

var1=5
Var2=6
i=5

Any help on this would be much appreciated.

Thanks in advance!


Solution

  • Here you are! Save the code below as VBScript file:

    ' VBS code variables to be fetched from
    sVBScriptDebug = _
        "var1= 5" & vbCrLf & _
        "Var2= 6" & vbCrLf & _
        vbCrLf & _
        "For i=0 To 5" & vbCrLf & _
        "   Msgbox i" & vbCrLf & _
        "Next"
    
    ' ScriptControl to be used for debug purposes
    Set oScrCtlDebug = CreateObject("MSScriptControl.ScriptControl")
    oScrCtlDebug.Language = "VBScript"
    oScrCtlDebug.AddCode sVBScriptDebug
    ' Me object from debug script
    Set oMeDebug = oScrCtlDebug.Eval("Me")
    
    ' ScriptControl for JScript utility function pushing all object's properties to array
    Set oScrCtlUtil = CreateObject("MSScriptControl.ScriptControl")
    oScrCtlUtil.Language = "JavaScript"
    oScrCtlUtil.Eval("Enum=function(x){this.x=new Array();for (var i in x) {this.x[i]=i};return this.x}")
    ' Retrieve JScript this object
    Set oJSGlobal = oScrCtlUtil.Eval("this")
    
    ' Cycle through all debug script Me object properties, that actually are fetched global scope variables
    sRes = ""
    For Each sVar In oJSGlobal.Enum(oMeDebug)
        sRes = sRes & sVar & "=" & oScrCtlDebug.Eval(sVar) & vbCrLf
    Next
    MsgBox sRes
