#import "libmysql.dll"

Here's another question, probably already discussed, but I might have looked... Is there no way to allow the tester to dll?

libmysql.dll - depends on MySQL version and is taken from the distribution.
can you tell me how to process a select query?
where import
string mysql_fetch_row(int MySQL);
At startup, you call it like this:
'mysql_fetch_row' - function is not defined
using #import "libmysql.dll"
function mysql_real_query - works...
and if it's not too hard, can you also post the code to search for strings, you know, through while
where #import "libmysql.dll"
string mysql_fetch_row(int MySQL);
where #import "libmysql.dll"
string mysql_fetch_row(int MySQL);
I have a crashlog - and MT4 crashes
Please tell me what is wrong.
I give you the crashlog
There has been a critical error
