Hello all! I am trying to access a dll located in the "c:/Program Files (x86)" folder in a 64-bits processor PC. If I use os.path.exists to check if the dll exists, I receive an afirmative answer: >>> print os.path.exists('c:/Program Files (x86)/Some Folder/SomeDll.dll') True But when I try to load the dll using ctypes, I get the fo...
I'm abusing distutils to compile an extension module for Python, but rather than using the Python C API I'm using ctypes to talk to the resulting shared library. This works fine in Linux because it automatically exports all symbols in a shared library, but in Windows distutils provides a .def to export only the Python module init functi...
I am working on a Windows application (EXE) that uses multiple DLLs. Development is in VCExpress 2005 (VC 8.0), using C only.

Any clues?? Code below: The FeeCalculation function is exported as follows in the DLL: extern "C" __declspec(dllexport) void __stdcall FeeCalc...

Here is my situation: I have a C project linking with many libraries (I haven't written this application), and it is shipped also with MSVCR71.dll and MSVCP71.dll. Even without those DLLs, the program has run fine on my system, which has MS VS2005 installed (indeed uses MSVCR80.dll and MSVCP80.dll). I've linked this application with ot...

I am trying to write some code that will allow me to dynamically load DLLs into my application, depending on an application setting. The idea is that the database to be accessed is set in the application settings and then this loads the appropriate DLL and assigns it to an instance of an interface for my application to access. This is m...
How would I use DLLImport pinvoke to invoke a function i wrote in a class in an unmanaged DLL? It always throws that the entry point doesn't exist in the dll. EX: class Foo { int __declspec(dllexport) Bar() {return 0;} }; Bar is in the Foo class. when I use pinvoke as: [DLLImport("Test.dll")] public static extern int Bar(); When ...
