问题
After a year using the MS Word 2013 VBA through ActiveX server calls under MS Win 8 Pro x64, the following call ends in error:
ActiveDocument.FormFields
Yesterday I made a Windows Update including a Security Update for MSOffice 2013 64-bit. Today I uninstalled the update, and the problem now persists.
1. Matlab 2014b
X=actxserver('Word.Application');
XD=X.Documents.Open('file.docx');
XD.FormFields
No appropriate method, property, or field FormField for class Interface.Microsoft_Word_15.0_Object_Library._Document.
Most simple direct calls into the ActiveX server properties still work well:
XD=X.Documents.Add;
XS=X.Selection;
XS.Font.Name='Courier New';
XS.Pagesetup.RightMargin=28.34646;
... etc
But any call for invoking a Document object (through .Documents.Add, .ActiveDocument, .Documents.Item(1), etc.) fails; listing their fields or methods shows nothing. Hence the subsequent calls to the Document object deliver no results:
XD=X.Documents.Add;
XD = Interface.Microsoft_Word_15.0_Object_Library._Document
get(XD)
struct with no fields.
invoke(XD)
<Nothing>
I also did not found any reference in Matlab Documentation to this behavior.
2. MS Word
Calls made directly inside Visual Basic Editor works fine:
MsgBox ActiveDocument.FormFields.Count
0
I was searching in the VBA Object Browser, but it still lists the Document object including an instance of the FormFields class. But the error suggest the _Document class do not, which is not listed in the "Object Browser" when i seek by using that underscored name.
Is there any reference on why the calls to these objects fail, while the standard simpler properties still works through the ActiveX calls?
回答1:
Solution
Repairing the installation
The option File>Options>Trust Center>Trust Center Settings>Developer Macro Settings>Trust access to the VBA project object model is Checked, which I suppose enable the VBA calls from ActiveX Servers (That is a guess).
Restart the System.
