you use b4a or b4j?
I have the same connection problem.
i use b4a.
Cau you post anythings?
Take post#10 and modify it according to post#20. That is a working solution for
@makis_best. In the other thread that you placed a question/comment,
@MrKim posted a working (for him) sample (see
https://www.b4x.com/android/forum/threads/mssql-jdbc-minimalistic-example.90548/#post-591195). If non of this seems to help (you actually try the solutions for yourself), then create a new thread and include
1) B4A version
2) What jdbc drivers you are using (jtds or MSSQL, please note that you may be out of luck when using MSSQL drivers)
3) Version(s) of the MS SQL server(s) that you are trying to connect
4) Can your server already be connected to from your network. How are other programs/devices accessing it (what IP/server name/port/dbname/etc configuration are they using to access your server(s)?)
5) Network topology (are you on the same network (your WiFi network is on the same LAN without restrictions), are you trying to access the server remotely, etc. etc. etc.)
7) Code that you are using to try to connect
8) Any and all things you have tried and the various error messages that you have encountered
And whatever other information you can provide that relates to your issue. Until then, it will be really hard to give a helping hand.
