Last change on this file since 9298 was 9286, checked in by sforsten, 12 years ago

#2018:

  • added new methods to the interface IStringConvertibleMatrix as well as two structs. Also the event ItemChanged has been changed to ItemsChanged
  • class ValueTypeMatrix now implements IStringConvertibleMatrix instead of the classes which inherit from it
  • small changes have been applied to a lot of classes to correctly implement the changed interface IStringConvertibleMatrix
  • solution file, Build.cmd and PreBuildEvent.cmd have been added
