See: http://www.delphipages.com/forum/showthread.php?t=216147 What the pages I found suggest as a solution is to extract the DLL from the resource to memory in the same place where it would be put using LoadLibrary. Then it could be called as if loaded from disk but the disk would not be touched. Digging down this route makes me hesitant since it involves using a number of rather big source files to handle the operations. Too big and involved for me to understand... >2) Load it directly from memory using a third party unit like this: >https://github.com/Fr0sT-Brutal/Delphi_MemoryModule This I don't understand, it does not look like they have embedded the dll into the application at all... In the example both tests use the same code to load the dll from the file system: ms := TMemoryStream.Create; ms.LoadFromFile(ParamStr(1)); (Paramstr(1) is the required DLL path) I found another MemoryModule at GitHub named BTMemoryModule: https://github.com/nedich/memorymodule But it too looks rather involved, and is pretty old... >3) Codesign the DLL and executable and verify that they haven't been >modified.

And I have no sources to the DLL, just the working binary. Conversion tool? ---------------- Is there some tool that can take a DLL as input and create an OBJ file, which then can be linked into the application? That would be the best solution at least for me. I have found objconv: http://www.agner.org/optimize/#objconv But it does not have an option to use a DLL as input file... Maybe it is not possible to do such a conversion I am after? -- Bo Berglund Developer in Sweden _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
