Development is a system, SERVER jacket is WIN SERVER2003 + SQL SERVER 2000, the program under the XP read very fast, but in the Windows 7 read data from the database is slow, what reason is this excuse me? Thank you very much!

Checked in the Internet?

In a 64 - bit Windows:
64 exe and DLL in the directory c: \ Windows \ sys tem32 directory.
32 bit exe and DLL in the directory c: \ Windows \ sys wow64 directory.
So pay attention to:
In win64 system registered under 32-bit ocx DLL to 32 ocx or copy the DLL to the c: \ Windows \ syswow64 \ directory,
And registered to c: \ Windows \ syswow64 \ regsvr32 XXXXXXX ocx or DLL
