We have a PB Application, say a LoginApp.
Users login to this application. Their username, password, access rights information validated/handled in this application.
There are other PB applications AppA, AppB, AppC, etc., which communicate to this LoginApp.
They get the information from the LoginApp, like who is the user logged in, which department, what's his role etc.,.
whenever user opens a window in AppA, it checks with LoginApp that this user has right to access this window.
based on the reply from LoginApp, AppA allows or denies to open the window for the user.
This whole communication is managed by DDE method (StartServerDDE, GetRemote, Remoterequest, SetDataDDE methods used).
Since DDE is deprecated by Microsoft, what is the best way to replace this DDE communication?
without affecting the nature of the applications and communication currently happens.

note: each app connects to different dbs. oracle 12c

We are using PB2017 R3, windows10 64 bit PCs. Also we use remote desktop services  windows 2016 OS.

 

Thanks.
