Test the value of OBJ_INFO_TYPE just before you evaluate the expression.
It should equal 1. If you haven't included MapBasic.def, or if you set
up a variable like obj_info_type, that could cause that error. Also,
it's better form to use the defined constants OBJ_TYPE_PLINE and
OBJ_TYPE_REGION instead of 4 or 7; it makes your code easier to understand.

Hi
I have what I believe is an object in a layer - I think it's a line -
if I query it in the Maspbasic window in MI with "select objectinfo
(obj,1) from table_name" then look at the selection table I see object
type 3 ie a line.
If I use the following line in some Mapbasic code which interrogates
the same layer:
If ObjectInfo(ColAlias, OBJ_INFO_TYPE) = 4 or ObjectInfo(ColAlias,
OBJ_INFO_TYPE) = 7 then
Then I get the following error when it gets to the object that I
believe is a “line”:
* (Blah.mb:123)ObjectInfo: argument 2 out of range *
If I write what is happening out to a text file ie
Print #1, (temptablearray(i) +" "+ colname+" " +colAlias + " "+
ObjectInfo(ColAlias, OBJ_INFO_TYPE)) where colAlias is the Alias of
the column name: ColAlias = Temptabname & "." & Colname
I get the following:
Query134
Query134 object Polyline 4
The top line above is the “line” that I think is causing the problem,
the second line above shows a result that works.
Is this “line” an object or not and can I do anything to avoid the out
of range error?
I hope this all makes sense!!
