Topic: What does the meaning of "Retrive attribute failed" error message?

[ekoneo]

When I renumber cogopoints whith:

Code: [Select]

for (uint i = 1, j = 1; i <100; i++)
                {
                    if (!civdoc.CogoPoints.Contains(i))
                    {
                    }
                    else
                    {
                        CogoPoint pt = (CogoPoint)civdoc.CogoPoints.GetPointByPointNumber(i).GetObject(AcDb.OpenMode.ForWrite);
                        pt.Renumber(j, PointNumberResolveType.Overwrite);
                        j++;
                    }
                   
                }

"Retrive attribute failed" error message occured..  Does anybody know the reason?

It appears that this exception is thrown when you attempt to renumber a point to the same number. So you cannot renumber point # 1 to # 1.

Thanks Jeff_M;
Thats true..
I should make up a way

I solved the problem by adding code part belowe:

Code: [Select]

if (pt.PointNumber != j)
                        {
                            pt.Renumber(j, PointNumberResolveType.Overwrite);
                            j++;
                        }
                        else
                        {
                            j++;
                        }

by the way renumber oparation ignoring when the point number is the same with for cycle's i value  :kewl:
