    Attempted to read/write protected memory

    Joseph Regan

      Good Afternoon,

      I have a VB.net program that has worked for several years that analyzes all dimensions of a drawing.


      In a particular drawing, the system runs through 4 dimensions before it crashes with a

      "Attempted to read or write protected memory. This is often an indication that other memory is corrupt." error.


      I have recently upgraded to solidworks 2015.

      The DLL version is


      Here is some code:


      swDispDim = swView.GetFirstDisplayDimension5

      swDim = swDispDim.GetDimension

      swTol = swDim.Tolerance


      if swTol.Type = Nothing Then  <--------------- On the fourth dimension, this is where the Read/Write error will occur, when trying to read the value of swTol.Type


      Any Ideas?

      Thank you very much for your time!
