We need to interface to 3rd party app, but company behind the app doesn’t

  • 0

We need to interface to 3rd party app, but company behind the app doesn’t disclose message protocol and provides only Windows DLL to interface to.

Our application is Linux-based so I cannot directly communicate with DLL. I couldn’t find any existing solution so I’m considering writing socket-based bridge between Linux and Windows, however I’m sure it is not such a unique problem and somebody should have done it before.

Are you aware of any solution that allows to call Windows DDL functions from C app on Linux? It can use Wine or separate Windows PC – doesn’t matter.

Many thanks in advance.

  1. Any solution is going to need a TCP/IP-based ‘remoting’ layer between the DLL which is running in a ‘windows-like’ environment, and your linux app.

    You’ll need to write a simple PC app to expose the DLL functions, either using a homebrew protocol, or maybe XML-RPC, SOAP or JSON protocols. The RemObjects SDK might help you – but could be overkill.

    I’d stick with a ‘real’ or virtualized PC. If you use Wine, the DLL developers are unlikely to offer any support.

    MONO is also unlikely to be any help, because your DLL is probably NOT a .NET assembly.
