Hi Song,

Can I use Word add-in libraries (WLLs) in Visual Basic(not WordBasic)?

I'm not sure exactly what you're asking. Do you mean, can you create a
WLL that uses Word-VBA commands? No, you cannot. WLL is old technology
that went "out of scope" in the move to Word 97, quite a few years ago.

You'd have to create a COM DLL Addin in order to use the VBA object
model.

My recollection is that a WLL is just a DLL with extra hooks so Word will
automatically load the WLL if in the Startup directory. Not sure I trust my
recollections.

However, if you have the original source, you are better off just building
an ActiveX DLL.

Dear Howard Kaikow!

Word automatically load the WLL as you said.
The MathType API consists of a DLL, a WLL.
I'd like to mathtype API in visual basic(not WordBasic).

To use mathtype API in visual basic(not WordBasic),
I tried to load mt5.dll and mathpage.wll in visual basic
, but failed.

Could I use matype API in visual basic(not WordBasic)?
Please give me some information about this.

Thanks!

A properly written ActiveX DLL can be used with VB.
You have to know how to pass the arguments.

I've never tried using a WLL with VB.

According to MSFT KB article 183758, one can use a WLL with Word 97, so I
would guess that you can.
The example they give shows building the WLL using C++.
