Re: Native vs. dbf / MI Pro vs. Map X

Dear Mike

You mentioned OLE in your last EMail.

If you are using OLE then you can open up Access in multi user mode.
You'll need a MapBasic program with a remoteQueryHandler in it and a VB
app that reads the Access records.

Use GetObject to link to an existing MapInfo Pro or CreateObject if you
run VB then MI.

You'll need to keep geometry in MapInfo and just one key field ( I also
keep two additional fields - one for thematics and one for labels). All
the other data can go in Access. Don't use MapBasic to read or write the
Access table ( because single user ) - let VB do this work.

Thematics are a bit code intensive - but here DBF comes to the rescue.
When you need a thematic, or labels, then build a DBF on the fly from
the Access table and then use OLE to get MapBasic program to dynamically
join this DBF to your MAP file.

Its tried and tested!

Regards

Bob
