Common problems and solutions for developing DATASNAP programs in Delphi XE8 (-) Start creating a good Dbexpress project when the error is made!

When we successfully created a server and client program that uses Dbexpress's datasnap, we closed the current project, and when we opened it again, it was possible that the problem would be:

Problem reason: This problem is because the current project group by default started the client project, the client program at startup, the visual design, need to connect the server, but our server did not start!

Workaround:

1, ignore the current error, enter the project, the default project to adjust to the server-side project. I suggest doing so so that we can start or stop any project at will.

2, start the server program first, wait until the server program starts, then open the project.
