Hi All,
I'm very new to VB.Net, and I've recently downloaded VB 2005 Express.
I've managed to connect a dataset to my installation of SQLExpress2005
and I have a form on which I have fields that display data from my
table as I scroll through the recordset.
I want to have a dropdown combobox on that form that stores the value
selected in the dataset of the other fields on the form, but which
displays the dropdown values from a different SELECT statement.
So, something like "SELECT DISTINCT projname FROM tblProjects ORDER BY
projname ASC".
I've been scanning through the help for hints but can't find anything
that shows me how to use a second recordset on a form.
Can anyone give me any pointers?
Much warmth,
planetthoughtfu l

Hi,
May I assume that you have instead of a recordset a Dataset or a DataTable
and probably code to get that one?
With a recordset you have first to use the conversion to a datatable to let
it work well. (There is an overloaded method from the dataadapter for that).

Hello all,
I'm thinking about overwriting the ListItem, so it can
contain x additional values (not only one).
Has anybody ever tried this?
Has someone got an example (C#)?
Can DropDownList handle overwritten Items, or will
additional Data be lost?
Thanks for any advice.

I have a combo box with a query for a list of names etc. The table has 250,000 rows. The query returns 250,000 rows. But the list returns only 97,000 rows and then shows blank columns after that, so it appears to be returning 250,000 rows but most of them incomplete. So, I have names from A to D but nothing after that.
The table was initially...

So I have a subform that lists the various items on a particular
invoice.
First, the user selects a product class from the Class dropdown. This
is bound to the Class field in the InvioceLines table. The rowsource
for the combobox is:
ClassName, ClassID, ClassSort
from the Class table, with the bound column set to ClassID.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
