I can create a "stand alone" (no runtime packages) app that works fine on the development workstation, but doesn't work when executed on a different workstation.

Did you deploy MIDAS.DLL and the driver DLL with your EXE? See dbExpress Applications: Deploying in the on-line help. -- Bill Todd (TeamB) Back to top David Guest Posted: Thu May 10, 2007 9:29 pm    Post subject: Re: Distributing apps using dbExpress Hi and thanks for the response. I did not deploy the MIDAS.dll or the dbexpora.dll with my app, but I thought the docs indicated that you didn't necessarily have to on a stand alone exe. I guess I am just not understanding the help document (or perhaps what it means when it says "To deploy dbExpress applications as stand-alone executable files, the dbExpress object files must be statically linked into your executable" I have the midaslib and dbexpora units referenced in my "uses" section. Is there something else needed to get the linker to include all the necessary pieces??

You can either deploy the DLLs or add the appropriate units to your uses clause. As long as you have done one or the other you have deployed everything you need to deploy. -- Bill Todd (TeamB) Back to top Bill Todd Guest Posted: Fri May 11, 2007 12:40 am    Post subject: Re: Distributing apps using dbExpress David wrote: Quote: but doesn't work when executed on a different workstation. Define "doesn't work". If you want help you need to provide a detailed description of the problem including the exact text of any error messages and the versions of the software you are using if you are not using the latest version. -- Bill Todd (TeamB) Back to top ssamayoa Guest Posted: Sat May 12, 2007 1:46 am    Post subject: Re: Distributing apps using dbExpress Quote: Hi and thanks for the response. I did not deploy the MIDAS.dll or the dbexpora.dll with my app, but I thought the docs indicated that you didn't Docs could be confusing: You can deploy dbExpress applications without dbexpXXXX.dll linking the driver using the apropiate unit in your source code. But dbExpress doesnt implies TClientDataSet support neither the opposite. For example, I use IBX with TClientDataSet then I must install midas.dll in the client computers. Bottom line: If you use TClientDataSet you must include midas.dll. Including dbexpXXXX.dll depends on if you included the respetive unit or not in your source code.
