Use the VBA debugger to analyze SAP GUI Scripting objects at runtime

[Stefan-Schnell]

Yesterday I discussed with a friend of mine about different methods of analyzing SAP GUI Scripting programs at runtime. One very easy method, to understand and to see where the attributes or methods are in the SAP GUI Scripting hierarchy, is the Visual Basic for Application (VBA) debugger and its watch window.

You can use VBA from a lot of applications, e.g. Microsoft Office Word or Excel. Press Alt+F11 to open the VBA IDE. At first you must choose the menu item Tools, References and search for the file C:\Program Files\SAP\FrontEnd\SAPgui\sapfewse.ocx, to bind the SAP GUI Scripting API to your VBA program.

Now you can use the following program to check the possibilities:

Option Explicit



Sub Test()



  Dim SapGuiAuto As Object

  Dim Application As SAPFEWSELib.GuiApplication

  Dim Connection As SAPFEWSELib.GuiConnection

  Dim Session As SAPFEWSELib.GuiSession

  Dim Window As SAPFEWSELib.GuiModalWindow

  Dim Coll As SAPFEWSELib.GuiCollection

  

  Set SapGuiAuto = GetObject("SAPGUI")

  If Not IsObject(SapGuiAuto) Then

    Exit Sub

  End If

  

  Set Application = SapGuiAuto.GetScriptingEngine()

  If Not IsObject(Application) Then

    Exit Sub

  End If

  

  Set Connection = Application.Connections(0)

  If Not IsObject(Connection) Then

    Exit Sub

  End If

  

  Set Session = Connection.Sessions(0)

  If Not IsObject(Session) Then

    Exit Sub

  End If

  

  Set Window = Session.FindById("wnd[1]")

  If IsObject(Window) Then

    Set Coll = Window.DumpState("")

    Stop

  End If

  

  Set Coll = Nothing

  Set Window = Nothing

  Set Session = Nothing

  Set Connection = Nothing

  Set Application = Nothing

  Set SapGuiAuto = Nothing



End Sub

 

Execute it in debug mode with F5, it stops at line 35. Choose the variable Coll and add it to your watch window. Open the GuiCollection in the watch window and view the complete hierarchy of the object and the values of the attributes, like in the following picture.

 



 

The VBA debugger offers many possibilities to analyze SAP GUI Scripting objects at runtime.
