No one have an idea my problem ?

What do you mean - you build the program and it compiles - Was there an error - did you debug it ?

Did you record to "Nop_Setting" table? There are some extending settings for Payment modules.

I use my own payment method which is i wrote EstPaymentMethod and but unfortunality my  connecttion is false..

Did you add a reference in the NopCommerceStore project to your new payment method assembly? As NopCommerce uses reflection to load a given payment method type it should know where its assembly is located, so if you add a project reference to your payment project it will be copied in the bin folder and later be found and loaded by the reflection API.

Hope this helps!

Thank you 7Spikes for your advice.
I added references before NopCommerceStore project.I added my payment method in the Payment method and i create web user control in the store and trying to integrate with db .
(Also i added new tables in the projects for save all payment transactions)
And I got some errors there :(

Anyone use for europe paymentmethods like Turkey ?
