Today, I turn on computer, start Lazarus and create a new project.
Add TSQLConnector, set its properties, and set Connected properties via Object Inspector and it worked!
But, as I wrote this post, I tried again to set Connected properties on and off, and the error came back!
Close again Lazarus, start new project & do the same, set Connected to True and it work again! Tried On/Off a couple time, still worked.
Very strange, I don't know why it works, still a mystery.
My environment :
- Lazarus 1.8.4 32 bit
- Windows 64 bit pro
- Firebird 64 bit client, Firebirs 3.0.3 Server
I will mark this post as SOLVED for now, will open again if problem reappeared again.
Thanks to all that have been help me.
Btw, for connection to database, I only use TSQLConnector, never use TIBConnection.
