Deployment

we do it like this.
in the database we add new table version, we store exe major,minor version details. and on application startup check that version with the one running if it is old then give a message to the  user and stop the application. though first time we need to install new version on all m/c'S.

is there any method to let all users executing one exe located at server in order to save the installation procedure?

Yes you can put a shortcut on user's desktop that refers the EXE in a server folder so that users will be using this version.

But don't forget that you still needs to install the package onto each user's PC to install all required components.

Another way (the way I prefer) is to create something (a small EXE or a batch file) that will copy everything form a folder on the server to a local folder, register any DLL/OCX and then launch the EXE locally.

emoreau, can you explain more about your prefer way?  

Create a small application (a kind of launcher) that will check a folder on your server containing the latest version of your application (including all the DLLs, OCXs, INIs, EXEs, ...) you want to keep updated and copy newest version to a local folder and register DLL/OCX. Once the synchronization is done, the "launcher" will run the application. Now replace the shortcut to your application with a shortcut to this launcher.

Thanks a lot.
