asp.net amazon itemsearch -

I am using Visual Studio 2008 and am trying to find API items like books or something. I'm just using accessKeyId, but when I click on the "Search" button to search the book, there is a signature error. Do I Need To Use Secret Keid? I have just created a new ASP.NET web site in Visual Studio or do I have to use the ADWS SDK for the net package?

Can someone give good advice thanks!

A signature error means that you have not made the request signature properly, you have to open SprightlySoft AWS for .NET. Component should be used. It's free and this product supports the Ads API. Get it. Does not work with ADS SDK Product Ads API for .NET.

Here is an example of calling the item search with the spreadsheet component.
