Sharing a Class between two executables

Hello,
I have an executable PROJ001.exe  which creates a global class called "RBSTrans" which allows all of the forms within this project to have access to the same instance of this class. PROJ001 now needs to call a number of new executables (ie PROJ002, PROJ002, PROJ003 etc...) . How can I make the instance of class RBSTrans available to these new projects (executables). An example would be great.

regards
Pat

I'm not sure I understand your environment, but if PROJ001.exe is a .NET executable, then you can add a reference to that assembly in each of your other applications. As long as the relevant classes are declared public, then you can create instances of this class in those other applications.

Thanks for that,
how do I add a reference to PROJ001.exe in PROJ002 and if PROJ001.exe already has an instance of my public Class , can PROJ002 reference the same instance ?

Within Visual Studio, right-click your PROJ002 project within Solution Explorer and select "Add Reference."

if PROJ001.exe already has an instance of my public Class , can PROJ002 reference the same instance ?
Now you are talking about working across process boundaries. This is not possible. You would need to set up some kind of inter-process communication (e.g. pipes, files, shared memory, remoting, etc.) in order to share data between processes.
