Any suggestions regarding default login |

IQA | Hi All,
I'm wondering if anyone else has had this situation and how they got around it. In a client / server app, the server creates the database and default users. Obviously I have to use the default Administrator / password in the session to do this. My question is, after the initial setup I don't want the server to use the default USER, but the thing is, my server app on running, checks the database / users exist and if not creates them. So the question is, how can my server know if its to use the default USER to login OR the one it creates after the installation without being able to first get to the Configuration.Users / Database information to check? I was thinking about storing a flag in the registry, but then I can see a user uninstalling the program and somehow the registry flag doesn't get removed even though I set it to in the uninstaller. Has anyone else had a similar situation? Maybe there a perfectly simple solution and I'm thinking in the box. Thanks, Phil. |

How about doing it like this: 1. For the initial setup use the default password. 2. After the setup remove the default username and default password from your main session. 3. Now the Session.OnLogin event will fire From the help file: << The OnLogin event is fired when the session is connected and the LoginUser and LoginPassword properties have not been assigned or have been assigned but are not valid. You can specify the user name and password via the UserName and Password parameters. The Continue parameter indicates whether the connection process should continue or whether the session should stop trying to connect. >> 4. Within this event you can get any information from your database by using a second session and either refuse the connection, create a new user and so on. Uli |

I did come up with a function that uses 2 try / catch statements to determine if either of the USERS exist as the session is connected and return a result of either default, live or none. int __fastcall TForm1::CheckServerUser(void) { bool CDSUserfound; int UserMode; // set session to LIVE login mySession->LoginUser = "liveuser"; mySession->LoginPassword = "livepassword"; try { mySession->Connected = true; mySession->Connected = false; UserMode = ltLive; CDSUserfound = true; } catch(...) { CDSUserfound = false; } if (!CDSUserfound) { mySession->LoginUser = "Administrator"; mySession->LoginPassword = "EDBDefault"; try { mySession->Connected = true; mySession->Connected = false; UserMode = ltDefault; } catch(...) { UserMode = ltNone; } } return UserMode; } //--------------------------------------------------------------------------- |
