Topic: C3D 2012 Point GetUserDefinedPropertyValue

[zeppeldep]

INTEROP COM Development.
Using C# 2010 to make apps for C3D 2012.
This is best answered by expert C3D VBA swampers, as I am using the COM.
I have created user defined point classification. Now I want to code the transfer from an existing C3D Point field to the custom field.
The code line issuing the Point method: GetUserDefinedPropertyValue results in 'Unspecified Error'
Any solutions?
Thx.
Kevin.

How about posting the code so it can be checked? And maybe a small dwg to test with?

Example attached ... current: cogo points have descriptions (Not the Field, the property - dont ask!).
Need to transfer these values to a custom field - already available in the dwg (custom class, general name)
This code, to read the custom fields works fine:

foreach (IAeccUserDefinedPropertyClassification udpc1 in CDb.PointUserDefinedPropertyClassifications)
{
    foreach (IAeccUserDefinedProperty udp1 in udpc1.UserDefinedProperties)
    {
        if (udp1.PropertyFieldType == AeccUDPPropertyFieldType.aeccUDPPropertyFieldTypeString)
        {
            listBox2.Items.Add(udp1.Name);
        }
    }
}

Error occurs when trying to set the custom field:  (default case):

IAeccPoint pnt1 = CDb.Points.Item(i1);
switch (listBox3.SelectedItems[0].ToString())
{
    case "Description":
        To1 = pnt1.Description;
        break;
    case "Raw Description":
        To1 = pnt1.RawDescription;
        break;
    case "Name":
        To1 = pnt1.Name;
        break;
    default:
        To1 = (string)pnt1.GetUserDefinedPropertyValue(listBox3.SelectedItems[0].ToString());
        break;
}

To1 = (string)pnt1.GetUserDefinedPropertyValue(listBox3.SelectedItems[0].ToString()); causes error - unspecified ...

Yes .. I know 1 refers to listbox2 and the other listbox3 ... I have not included all the code ... that is not the problem ..
