Hi,
I don't think anyone can access paypal for verification, we have to get a subscribtion to use paypal. Then there may be some web services available in paypal.com, there we need to send variables and that web method verify our input and provide output, better to get touch with paypal support.

Have you used Ajax before ? Read up on it ? Know what it is ? Have you downloaded ATLAS ? Or are you stabbing in the dark ?

I have one web user control which consists of one Button web control.
I have 3 aspx pages in which i have to use this web user control. But when iam going to click on the button it should perform different actions in different aspx pages.
|
|
|
|
|
You can handle the click event in the aspx page. What you need to do is to create a event handles and handle in aspx page.

Hi,
I have a project in which the operations are categorized based on the roles. The roles are DataEntryOperator,Moderator,Admin,Client.These roles are stored in database. A login screen is provided. The pages are created in 4 different folders in the project.Now if a peroson tries to access a page outside his/her folder he should be immediately redirected to the login page. How do I do this? I tried but couldn't
With Regards,
Uma

You can check the role of the user in the page load event of the page and can do the operations as per the requirement.
