    Take a look at the CallByName function.

    Play with this

    Code:
    Option Explicit
    'add a reference to microsoft script control
    'yes, they call it a control, but you can add a reference to it
    'via menu->project->references
    Private myScript As ScriptControl
    Private Sub Form_Load()
    
    Set myScript = New ScriptControl
    'you need to tell it you want to use vbscript
    'and not microsoft Jscript
    myScript.Language = "Vbscript"
    'add your sub or your function
    'remember you DO NOT have the "private" 
    'or "public" statement here 
    'do not forget  you do not have data type also,
    'but only variant variables
    '(but you can use Cstr, Cdbl, Cbool and so on
    'if you need)
    myScript.AddCode "sub showmyMessage" & vbCrLf & "MsgBox ""Ehy, does this really works?"" " & vbCrLf & "end sub"
    'Now run the added sub or function:
    myScript.Run "showmyMessage"
    Set myScript = Nothing
    End Sub
    By the way: did you already vote?? (see below, red lines)

    The CallByName function works with Any function, including your own.

    Question Nearly There . . .

    Cheers Cimperiali


    I have adapted that code but get error 424

    Object required: 'DataReportEEList'

    The code now looks like ;


    Private Sub ScriptReport(RepName As String)

    Set myScript = New ScriptControl
    myScript.Language = "Vbscript"

    myScript.AddCode "Sub ShowReport" & vbCrLf & RepName & ".Show 1" & vbCrLf & "End Sub"

    'Now run the added sub or function:
    myScript.Run "ShowReport"
    Set myScript = Nothing

    End Sub




    What am I doing wrong ? the report is in the project and the name is the same ?

    Hi Cimperiali

    I tried your code, and it worked well.
    But when I tried changing the procedure to a function which takes parameters, I encountered an error like - "Object does not support this property or method", or so

    Suhaib,

    The run method automatically returns the value from the function

    Judgey,

    If you want to access an object (say a form) inside the script try to add it first by issuing the AddObject method

    s.AddObject "MyForm", Form1

    Suhaib,

    myScript.AddCode "function hello(byval name)" & vbCrLf & "hello = ""hello "" & name" & vbCrLf & "end function" & vbCrLf

    varRet = myScript.run("hello", "Suhaib")

    MsgBox varRet

    Got it?

    The vba.CallByName is applicable too for methods (sub/func) within the object. The object can be a form.
