Stored Procedures and 'long' vs. 'number' data type
If I create a datawindow fed by a stored procedure, I'll sometimes get an
error if I specify the type as 'long' in the dw and the value that is
returned by the stored procedure is negative. I think the error is "Numeric
value out of range". If I change the type in the dw to 'number', all is
I guess my overriding question is, are there any negative implications in
using 'number' as the data type in the datawindow as opposed to 'long'?
I'm using PB 9.0, build 6066,
and MS SQL2000 on the backend.
The data type being returned...Cast from type ''''DBNull'''' to type ''''String'''' is not valid.
How do I avoid getting this error:

I am trying to get values from the database into a form for updating using a Datareader, SQL is set to allow nulls for certain fields as they are not required but the only way I can get the form to display is by adding a space in SQL.
Is there another way around this?

I'm working with GridView for sorting
The error message is that "Unable to cast object of type 'System.Data.DataView' to type 'System.Data.DataTable'"....
Dim m_DataTable As DataTable = GridView1.DataSource
How can I change the code above?
Well let's see, if your DataSource is a DataView, you can get its associated DataTable object using the .Table property:
Dim m_DataTable As DataTable = GridView1.DataSource.Table
or in a land of strict typing:
Dim m_DataTable As DataTable = CType(GridView1.DataSource, System.Data.DataView).Table

I can't figure this one out.
I created new solution in vs2005 from using vs2003 and I have a problem I can't find an answer to.
I get the following error that relates to passing a system.data.datatable to a dataset.datatable named "ProductList.PRODUCT_LISTDataTable". It says it can't cast the object from one type to the other, and I've tried "CType" and doesn't work.
