insert null value

Question

Hi everybody,

 

I have this:

 

[code]

 

Dim IJavaValue As String = "" '= System.DBNull.Value.ToString()

If String.IsNullOrEmpty(IJavaValue.ToString().Trim) = True Then

IJavaValue = DBNull.Value

End If

[/code] 

 

Then I get the message: Error 43 Value of type 'System.DBNull' cannot be converted to 'String'

 

And if I try this:  IJavaValue = DBNull.Value.ToString()

 

But then If I look in the Databse I see an empty column and not the value 'NULL' in the column

 

Thank you
