Outlook 2010 Script

I'm a beginner in terms of C++ but I'm trying to create a script that changes the default address book in Outlook 2010. At first I looked at changing the registry which works for an individual user, unfortunately all the registry values are unique to the user though so it can't be rolled out. I then found a C++ script which works perfectly. Unfortunately it doesn't work when a certain option is selected in Outlook, any other option it's fine, but when "Choose automatically" is picked (Which it is by default in my case) it can't change it.

So, the script I found is here and the code I know needs to go in is located here. Unfortunately, being the newbie to C++ that I am, I can't seem to put them together. Any help would be much appreciated.

Thanks in advance.

The main script is:

//
// Set MAPI Default Address List when opening the Outlook Address Book
//
// If Outlook is already open, it may need to be restarted for change to take effect.

It seems that this part needs to go in somewhere:

#define PR_AB_CHOOSE_DIRECTORY_AUTOMATICALLY PROP_TAG( PT_BOOLEAN, 0x3D1C)

hr = lpSession.OpenProfileSection((LPMAPIUID)&IID_CAPONE_PROF, NULL, MAPI_MODIFY  , &lpProfileSection);

if (SUCCEEDED ( hr = HrGetOneProp(lpProfileSection, PR_AB_CHOOSE_DIRECTORY_AUTOMATICALLY, &lpPropValue))){

lpPropValue->Value.l = 0;

   if (SUCCEEDED(hr = HrSetOneProp(lpProfileSection, lpPropValue)))

And also:
