Get Table Cell Field Data

[thobbs]

I have a table cell that contains a field linked to a block attribute.

 

When I use the GetCellValue method it returns the text value of the attribute.

 

How do I retrieve the actual field data, for example:

 

%%).TextString>%

 

I'm primarily interested in retrieving the ObjID of the block containing the attribute the field references.

Problem solved for my specific instance.

 

Starting with a table cell (row 0, column 0) that contains a field as formatted above:

 

Store a reference to the active document:

 

(setq activedoc (vla-get-activedocument (vlax-get-acad-object)))

 

Get the Table object by user selection:

 

(setq table-obj (vlax-ename->vla-object (car (entsel))))

 

Get the field ID of the cell:

 

(setq pfieldid (vla-getfieldid table-obj 0 0))

 

Convert the Field ID to an object:

 

(setq pobject (vla-objectidtoobject activedoc pfieldid))

 

Apparently field objects are not fully supported in VLISP, so I needed to get the DXF entity data of the field to continue:

 

(setq pdxf (entget (handent (vla-get-handle pobject))))

 

This is the parent field data. From here I retrieved the Child Field ename from code 360 and then the DXF entity data:

 

(setq cdxf (entget (cdr (assoc 360 pdxf))))

 

Code 331 is the ename of the attribute reference and I used this to get the attribute reference object:

 

(setq aobject (vlax-ename->vla-object (cdr (assoc 331 cdxf))))

 

Finally I retrieved the Block Reference object using the OwnerID of the Attribute Reference object:

 

(setq bobject (vla-objectidtoobject activedoc (vla-get-ownerid aobject)))

 

I only tested this on 32Bit AutoCAD 2011. For 64Bit use GetFieldId32.

 

Any comments would be welcomed.
