I hope to get some advise from those who had used mql5 with sqlite.
I created a wrapper which run successfully as a standalone, running in a dos prompt.
But when tried to run via mql5, it seems that it is unable to read or write under MQL5\Files folder.
I am running on Vista and run terminal.exe on both normal and administrator rights to execute the sqlite reader, but was still unable to do this successfully.
Could it be some issues on the mql5 dll import functions and mql5 file access security?
Lastly, is it possible to have a Collections or List Objects to be returned from DLL to mql5 which both can understand and interact with?
I'm interested too in a wrapper for MQL4 or 5.
So many wrappers on official site, but I don't know which one would work, and I don't know how to create a wrapper dll myself.
So i'm interested in some opinion about how to use SQLite on MT4 and/or MT5.
Try to read this article (https://www.mql5.com/en/articles/69).
Could you explain your problem with reading/writing in MQL5? Have you any example?
