Delphi7+ADO+MySQL5.1 ODBC Driver

[Maks Nazarenko]

Hi to all. (sorry for my english :) )

I have Delphi7, MySQL 5.1 on localhost, MySQL ODBC 5.1 Driver, and using ADO components for connection.

MySQL:
default character set=latin1

table `A` - engine MyISAM, CHARACTER SET cp1251
field_1 int not null AUTO_INCREMENT
field_2 varchar(20)
PRIMARY KEY(field_1)

Problem:
If table `A` is empty - everything OK, but if there is at least one row, then i have "The supplier of information or other service returned the state of E_fail"(approximate translation) error when make ADOTable.active:=true.
But if table `A` have UTF8 or latin1 CHARACTER SET, then i have no problems.
I tried add "SET CHARACTER SET CP1251" to my connection string:
Provider=MSDASQL.1;Extended Properties="DRIVER={MySQL ODBC 5.1 Driver};user=someuser;password=somepass;DATABASE=somedb;OPTION=3;INITSTMT=SET CHARACTER SET 'CP1251';" but it does nothing!
If in connection string write "charset=cp1251" then i have "Access violation" in myodbc5.dll.

I know i can use UTF8, but i need cp1251, and using of UTF8 will be last step, if i don't found another solution.

Anybody know how to fix it? Thanks.
