filling values from dataset

Hi All,

I have a need to assign values from my dataset to a variable but when i use string (which its normally text) and the item in that row of the dataset is empty it tells me that conversion from DBnull to string is not valid

how do I get around this?

That depends how you want to handle null values. If you want a null from the database to correspond to Nothing in VB then you will have to test for null first and only get the value if it is not null. There are various ways to do that but the DataRow class has its own method for doing so so, if you're using a DataRow, you should use that, e.g.

Code:

---

Dim name = If(myDataRow.IsNull("Name"), CStr(Nothing), CStr(myDataRow("Name")))

---

If you want a null from the database to correspond to an empty string then you can simply call ToString on the field because DBNull.ToString returns an empty string.

lovely, .tostring was what i was after.

Thanx heaps
