Slickedit 17 comes with an example extension dll project, simple.dll which has a makefile and is geared to 32 bit. I am running SE 64 bit and have been told my old 32 bit dll won't work - it gives an obtuse file not found error when I try to dload() it. The dll itself is mostly a bunch of utility wrappers for common windows user.dll functions like WindowFromPoint().
What I would like is a starter project for building a 64 bit SE extension in Visual Studio 2010, and any pointers anyone has for wrapping these type of functions.
