Hi am trying to read the content of a visio page where as am able to read the below images and it shapes along with the connectors too ,where as am able to read this type of connectors,

but am not able to identify the connectors of the below image but an able to nread the content of the image.

the below method is to find wether its connectors or not
private bool IsConnector(Shape shape)
{
string objType = shape.get_Cells("objType").Formula;
if (objType == "2")
return true;
return false;
}
where as if the connector is in the shape similar to first image then am getting value 2 in objTyp ,but it return value 0 for second image.
- I need to know what is the purpose of using
string objType = shape.get_Cells("objType").Formula;,because it return 2 for connectors in firstImage and other value for connector in second image - Why it return other that 2 for the connectors in second image.
