Hello everyone!

I have encountered some problems:

I need to find some of the specified parts in the assembly by the component property name (eg 'Description').

I run the VBA macro code in the API help - sample code 2015 SOLIDWORKS API Help - Traverse Assembly at Component and Feature Levels Using Recursion Example (VBA) , which runs very fast (38.3828125 sec).

But I am more good at VB.NET, so I also run the vb.net code 2015 SOLIDWORKS API Help - Traverse Assembly at Component and Feature Levels Using Recursion Example (VB.NET) , but running up to 261.755971599996 sec!Much slower than the VBA macro code,nearly 7 times.

I am very puzzled why such a problem.

Could anyone give me some answers?
