  We have a C++/CLI application exposing an FpSpread instance in CMFCWinFormsView.

  This compiles and runs successfully using Spread 13.

  Attempt to port to Spread 18 produces many errors like the following.

  D:\AsteroidSource\ASTEROID\trunk\ASTEROID\ClusterEditor.cpp(101,28): error C2371: ‘FarPoint::Win::Spread::FpSpread::_a’: redefinition; different basic types
  
  (compiling source file ‘/ClusterEditor.cpp’)
  
  D:\AsteroidSource\ASTEROID\trunk\ASTEROID\ClusterEditor.cpp(101,28):

  I feel that I may have seen issues like this on earlier ports. Can anyone throw any light on this?

  Hi Aastha,
  
  I made a very simple example consisting of a User Control (FpSpread18ControlLibrary) and a test C++/CLI application (TestFpSpread18) using CWinFormsView that demonstrates this problem.

  I’ve attempted to attach the source here as zip files.

  Regards,
  
  Peter.
