Great library. Too bad it doesn't support Cyrillic alphabet.

Version 3.0 does.

Valentin Dobroletov:

has anyone converted to UTF-8 ?

Dear experts, please advise me.
For 2 years 32-bit permvar2.dll (from MessageBoxW(uint hWnd,string lpText,string lpCaption,uint uType);

int PVInit(string);
int PVValue(int,string,int);
int PVGetValue(int,string);

Compiles, but gives error :
'C:\Program Files\ForexClub MT5\MQL5\Libraries\permvar2.dll' is not 64-bit version
Cannot load 'C:\Program Files\ForexClub MT5\MQL5\Libraries\permvar2.dll' [193]

If calling permvar.dll
#import "stdlib.ex5"
#import "permvar.dll"

Message :
unresolved import function call

Can it be initiated differently ?

This is a bit off-topic, but MT5 terminal gives you a hint - your library is 32-bit, under MT5 you need a version compiled for x64. It will not work otherwise. Ask the developers if there is a 64-bit version.

Dmitry Melnichenko:

Maybe a little late but still.... I need to know for testing:

1. Is the Expert Advisor run on different terminals? Or on the same terminal but on different charts?

For different terminals DLL is loaded into its own memory area and there should be no such collisions.

2. the WHERE phrase is framed in brackets, in principle it should not affect, but still it is not a standard SQL.

3. what does the SqlModifyClient(ticket, open_ticket) function return ?

4. what version of MQLMySQL.dll is used?

I will try to test

The latest release has in-house DatabaseXXX functions that implement in-house Sqlite bases.

Hi, wow thanks for all of this, there's a problem with my notifications so I've only just seen that you did this several months later.

Thanks very much, great work.
