aspx_professional thread: VB6 to VB.Net Upgrade Error


Message #1 by "Sachin Mhatre" <sachinx@h...> on Wed, 05 Mar 2003 15:47:58 +0530
You can also get that error if you are trying to move the contents of a
database field which is null to a string variable. For instance:

myString = myDataRow(0)

If myDataRow(0) is null then you get the error. This is a very common
problem. If this is your problem then the solution is very simple.  If you
add an empty string to the expression then the cast will take place
properly.  This is the correct (and very trick) code.

myString = myDataRow(0) & ""

Regards

Means you are assigning wrong data type to a variable. Use System.convert
class to convert the value before assigning it.
