Want to learn LINQ? looking for a lightweigh and fast application to evaluate your linq expression? now check this out. i found a very good free application which lets you interactively query SQL databases in a modern query language: LINQ. LINQPad is also a great way to learn LINQ: it comes preloaded with 200 examples from the book, C# 3.0 in a Nutshell.  And finally LINQPad is more than just a LINQ tool: it's a code snippet IDE that instantly executes any C#/VB.net expression, statement block or program. Put an end to those hundreds of Visual Studio Console projects cluttering your source folder! you can get it from here.

if you want to develop and ECommerce application in .net, you should definitely check the post regarding a real eCommerce article. For sure it will help a lot.

one issue we usually face while developing an ECommerce application is testing credit card  payment system. so here is list of credit card numbers we can use to test payment system.

American Express: 3111-1111-1111-1117

Visa: 4111-1111-1111-1111 or 4222-2222-2222-2222

MasterCard: 5111-1111-1111-1118 

Discover: 6111-1111-1111-1116

remember that  CCV number and Name does not matter but you should keep the amount bellow $500 dollars and also make sure expiration date is not today but in the future.

Example:

CCV:123

i just found a set of java and eclips learning videos. these are good mostely for begginers.

you can find them here

here is a quick comparision between microsoft c# (.net) and java 

in the last sub system which we were working on, there was requirement to export the result of a query which is from oracle database and is displayed in an asp.net data grid into excel file. but the component we are using for export to excel functionality gets the collection as input parameter and export the data to excel file and write the excel file into response object of the asp.net. this means once the functionality is invoked, a dialog box will be displayed asking Open the file, save the file of cancel the operation. no issue with save and cancel. but when they clicked on the open it opens the excel file in the same browser window where they were viewing the page and they close the window once they were through with viewing the excel file. this means they close the application.

now they needed the excel file be opened in a new window so that they will not loos their application states. what we did to do so is a little bit tricky. in the query page when user clicks on export to excel button we save the data to be exported in an asp.net session state and open a new browser on the user's machine using following code :

and we also moved the export to excel logic to the ExcelExport.aspx page
