Programmatically set "Trust Access To Visual Basic Project" to on, then off (Tools > Macros > Security > Trusted Publishers tab)

Hi.  I'd like to keep my users from having to set this Macro security setting in order to use my template with buttons.  Also, I don't think it is a good idea to leave it checked.  What is the code to change the setting to on when the document is opened, then to change to off when the document is closed?  I can't find the setting in the Word VB objects browser.  If it can't be done, fine, I'll just make the users do it as part of "setting up the tool"... but I have some real doozy users and it would be nice to do this automatically for them.

Hi e,

This can't be done via code, for an obvious reason: this setting is there for security reasons, and that security would
be worthless if malicious code could disable it :)

Well, maybe it can be done with some arcane Registry tweaking using APIs.  IMHO, you're better off not going there...


It would not be logical to allow the code to set access to itself so, no, it can't be done by design.
I'm not sure about this but would creating a certificate and signing the word template help? The users would have to trust your certificate. Once they did that, opening templates signed by you would be seemless.

Just something to look into, I haven't actually done this.

This is a different issue.  The "trust access to the VB project" setting controls whether or not to
allow programmatic access to the VBProject itself or its dependent objects.  For example, if this
access is allowed, you can write code that actually edits code elsewhere in the project, among
other things.

For example, I have code that imports BAS files as new modules into the ActiveWorkbook's VBProject;
that code only works if programmatic access is allowed.

Thanks for the info Patrcik!
try this:

Set wsh = CreateObject("WScript.Shell")
'key to modify
str1 = "HKEY_LOCAL_MACHINE\Software\Microsoft\Office\" & _
Application.Version & "\Word\Security\AccessVBOM"
'enable access
wsh.RegWrite str1, 1, "REG_DWORD"
'read the vba project name
MsgBox Application.NormalTemplate.VBProject.Name
'disable access
wsh.RegDelete str1

I knew it was possible; I typically tell people to stay *FAR* away from manipulating the Registry :)

BTW, how would one test to see the current setting, so that the change would only be needed if the
user is currently not allowing access to the VBProject?

using on error resume next statement and testing for error...
