I tried ... db.EnableExtensions(true); db.LoadExtension("libsqlitefunctions.so", "sqlite3_extension_init"); ... -> error message: modul not found It worked fine within "SQLite Expert Personel". I can load/unload it and use the math functions (e.g. select cos(45) no problem. Then I tried to implement it in my little VisualStudio 2010 project. That does not work. Why ? What is wrong ? (sorry I'm a dotnet beginner, but I could not find anything helpful in the net). Thanks for help Simon

I realized that you have already included LHMs lib. So I wrote my own lib (libsimon.dll) with my own function but the error stays.

Is the DLL to be loaded located along the PATH or in the application directory?

I took LHMs extension-functions.c file: 1.added my simple rownum(n) function 2.added this function to the scalar function registration array in the file 3.commented out all other scalar and aggregate functions from the both registration arrays in the file then I compiled the file: gcc -g -shared extension-functios.c -o libsimon.dll I copied that .dll file to a directory which is incluede in the PATH environment variable AND I copied it to my project VS Studio project directory into bin directory.

Is this being done on Windows? Are you able to load the DLL into the Dependency Walker (see "http://www.dependencywalker.com/") tool and double check that no errors are seen?

I can't see any errors in dependencywalker. I just see a lot of information which tells me nothing.

Yes it is Windows 7, 64bit

Ok, I think that may explain the issue. Make sure that the DLL you compiled is 64-bit if the application process is 64-bit. The Dependency Walker tool can tell you if the DLL is 32-bit or 64-bit. Task Manager can tell you if the target application process is 32-bit or 64-bit.
