Insertion problem with ASP.NET AccessDataSource

If you try to use ASP.NET AccessDataSource then you may face a problem while inserting rows to database through the dataSource. It happens when you have an auto increment identity column. When you drag & drop an AccessDataSource Visual Studio.NET generates the SELECT, INSERT, DELETE, UPDATE Command for you as your chosen option. But you will get exception message when you try to save a new row. The cause is the generated insert query is wrong. Actually VS.NET don't consider the identity column and try to insert value in the column.

The work around is just remove the ID column from the insert command and remove a parameter('?') from the query parameter list. Also remove the ID column info from the insert command parameter collection.

Then you will find its working fine.

I think every developer should be familiar with some software testing terminologies, especially different methods of testing. You may have heard about White Box Testing, Black Box Testing, Unit Testing, Regression Testing, Integration Testing etc. If you don’t want to spend much time after this but feeling interest to know about then visit the following link. Its a very simple and short article.

Mounting NTFS partition in Debian

Currently Debian doesn’t support mounting NTFS partition in read/write mode. You can only mount in read only mode.

To mount in read/write mode you have to install third party package/driver. NTFS-3G is the favorite one.

Here is the detail info.
