Hey Everyone,

I'm currently using the Maptools library http://shapelib.maptools.org/[^] with it's c# .net wrapper in a project to create shape files.

I've added the Maptools dll to my references, and included the shapelib.dll to the project.

Under Windows 7 x64, Windows 8 x64 everything works fine. When i try it on windows 8 x32 i get an 'Unable to load shapelib.dll HRESULT 8007007e" error.

My project currently is targeting 'any cpu' and I've tried 'x86' but whenever i try to create the shape file I get this error.

Any helpful hints or advice would be appreciated.

Cheers,
Ethan

The author of the library provides a contact address on the web-site; why not ask him ?

Solution 1

From behavior you described it looks like shapelib.dll is compiled for x64. If that's the case you will not be able to run it on 32 bit machine.

Solution 2

Testing on various machines indicated that it was compatible with both x64 and x32. I was not able to trouble shoot this problem further. I ended up migrating to the DotSpatial libraries which solved all my issues.

Thanks to those that contributed.
