Is there a isNull function? in VB.Net

[eLawman]

Do you know of any isnull function buried in a namespace or anywhere. I'm checking data as it comes in from DB. I just want to set it to blank string and to do it faster than take incoming data and .toString it.

Thanks

To slow, and plus I had time to also put a link in....lol

for setting null value use

DBNull.[B]Value[/B]

not tostring . and there are another checking null values in rows collection of dataset :

If MyDataset.Tables(MyTable).Rows(0).IsNull(0) Then
MessageBox.Show("No password was configured")
'do this
Else 
'do this
