I need to run multi-instances of my WinForms C# application. What issues can I expect?
I'd like to use the same EXE. BUT, each instance will be associated with a unique copy of an Access database. Each is a different restaurant with a unique identifier.
1) How can the program know if a given restaurant is already running? I want it to load no more than one time per restaurant.
2) I use Microsoft MapPoint's ActiveX control. Will they automatically share it and will Windows handle the multi-user aspect of this use?
3) I intend the first instance to be the only instance which can dispose of the MapPoint ActiveX COM object. Refreshing this instance is an important thing to do to keep it working properly I am told by Microsoft, at least for the 2004 version.
4) How can I make different instances of the EXE communicate with one another?
What difficulties/challenges does this model present?
