Hi there,

I am developing a winform application[with c#] with SQL Database [attached].

All process with SQL query are OK, but at the first time when application open and user Login for application; SQL query takes too much time [may application is HANG or STOP working (say for 5-6 seconds) and then after successfully login application start.

After it; all SQL process will executes well.

If user close application and start over again ... it's again slow / Hang/ Not working starts....

I can't getting wht is matter with this...?

Can you tell me what is mistake in my query?
