Meta Trader 4 Expert in DLL files

MQL4 Experts Libraries

Specification

Hello

I have an expert advisor which is stopped functioning after the changes made in MT4 600+ build.

Basically the EA has been updated with the change in code but it is giving "MT4 Terminal Access violation read to 0xFE8357C8 in ‘msvcrt.dll’.

Not sure if it has anything to do with 32 bit or 64 bit of windows 7 version.

If you have come across this or know the solution please advise as soon as possible.


NOTE:

The msvcrt.dll is not a part of the EA it is windows system dll. It is using the MT4 MySql library and the issue that everyone is facing while using this library in 64 bit
environment.

If you are able to use the MySql library provided by MT4 for 600 build (https://www.mql5.com/en/code/download/11114/mql4...), in both 64 and
32 bit environment. You must try insert and update operations on multiple columns of MySql database table. If this can be done then that would be the solution.
