Huiz,
Your correct about not having many samples on the subject, I've found very little, and what I have found is mainly in C which I have difficulty converting so that I can test it. This is the first attempt at using map. I'm looking into it because we have a need to add or attach and edit attribute information for a design specification. we also have a need to add classified objects. I've created an xml definition file much like the industry standard files supplied with map, it seems to work well enough but its difficult to create and edit. It works great for attaching the object data tables but it has no editing for field value attachment unless the value is default to the object data table from which the classification file was created from. It world be great to be able to draw the geometry and attach at the same time. if I can't figure this out I guess I'll have to look seek out someone who can. The best that I've been able to do in the last week or so is to test that the dwg has object data tables, if it does I loop thru the tables name and add them to a comboBox, next it loops thru the field definition names of a named object table and adds those items to a comboBox, next with a selection in the field definition names it prints a list of the values for that single field, that's about it. I know I need to figure out how to better index all the items, that's where I'm going to focus because project will have about 25 object data table names and each one of those has been 6 and 25 field definitions name that require a value. The only AutoCAD Map process that comes the closest is editing shape file dbf thru the data table. maybe it that direction could be an option if the object data tables are already assigned to the objects.
Thanks for the encouragement
John
