MySQL Bugs and Errors

MySQL Administrator Access Violation under Windows

When you select "Startup Variables" in the free "MySQL Administrator" you receive the error: "Access violation..."
Quickly looking into this, it looks like MySQL Administrator can not find the my.ini configuration file.

Solution:
Editing the "MySQL service" registry settings at:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MySQL

Modify the ImagePath entry to include the location of your configuration file like:
"E:\Program Files\mysql40\bin\mysqld-opt.exe" --defaults-file="C:\WINDOWS\my.ini" "MySql"

Error: Can't create/write to file...

I was getting error messages about: Can't create/write to file ...
Solution:
It was solved this by use forward slash in the path like:
tmpdir=T:/temp

Regular backslashes work just fine in the other MySQL path definitions/directives. But it looks like in the world of MySQL, Apache...etc... it is usually better to use forwardslashes.
