I have the scripting control working but I cannot figure out how to allow the script access to parts of my application. Thanks.

Gambit I want the scripts to be able to access values and functions in my application so that the scripts can be used to extend the application. I read some things online that indicated calling AddObject to register an Automation Function would do the trick. I then did some searching on Automation Objects and only found examples in Visual Basic or Delphi, not C++ and suitable for C++ Builder. I was hoping someone somewhere would point me to a skeleton application that shows how this can be achieved. Thanks!

That much was already understand from your original post. You did not answer my question. Which SPECIFIC interface(s) that has the AddObject() method are you trying to work with in your code? Again, please provide SPECIFIC details. Quote: I read some things online that indicated calling AddObject to register an Automation Function would do the trick. I do not know what you read online, but there is no AddObject() method for accomplishing that. What you should be doing is the following: 1) derive a class from the IActiveScriptSite interface 2) Use CoCreateInstance() to instantiate an instance of the IActiveScript interface using the CLSID of the desired scripting engine that you want to use to parse script code with. You can use CoCreateInstance() to instantiate an instance of the ICatInformation interface and then call its EnumClassesOfCategories() method to enumerate the installed engines, specifying CATID_ActiveScriptParse as the category. 3) query the IActiveScript for the IActiveScriptParse interface 4) call the IActiveScriptParse::InitNew() method 5) call the IActiveScript::SetScriptSite() method, passing it an instance of your IActiveScriptSite-derived class. 6) call the IActiveScript::AddNamedItem() method for each named item that you want to expose access to 7) call the IActiveScript::SetScriptState() method, specifying SCRIPTSTATE_CONNECTED With all of this in place, you can then pass script code to the IActiveScriptParse::ParseScriptText() method when needed. When the script encounters a named item that you specified with the IActiveScript::AddNamedItem() method earlier, the script triggers the IActiveScriptSite::GetItemInfo() method of your derived class. The GetItemInfo() method can then return the IUnknown and/or ITypeInfo interface pointers for the appropriate Automation object that you have designed to manage the specified named item. For instance, if you had the following VBScript code: If App.SomeProp = True then App.DoSomething End If You can create an Automation object for your project that has a Boolean property named SomeProp and a method named DoSomething. The Automation object has access to your application's internal data and such. Then instantiate an instance of the Automation object at runtime, specify an item named 'App' to IActiveScript::AddNamedItem(), and then have IActiveScriptSite::GetItemInfo() return the IUnknown and ITypeInfo interface pointers for the Automation object whenever the script needs to access an item named 'App'.

I don't know much about ActiveX, so all I know so far is if I drop the Microsoft Scripting Control ActiveX component onto my form, the resultant object, which is a TScriptControl, implements an AddObject function. I did a search on google groups for "microsoft scripting control addobject" and there are some examples of it's use but for different languages. I'm not sure what other AddObject functions there could be in relation to this problem, but I'm sure I will run into them along the way.
