Hi,
Can the DataTable.Select Method use 'Distinct' to remove duplicate rows? If
so how? I tried, however code triggered error 'no colmn 'Distinct' found'.
Thanks

Hi,
I´m trying to use the Select method for the DataTable
objects of the System.Data library. The problem is that
when the datatype of the object that's being searched is
an string, I get the correct DataRows from the DataTable,
but if the datatype is an integer or a decimal, then I
get nothing...
Here´s part of the code

Hi,
Has any one ever compared the performance of calling a DataTable's
Select method with a stored procedure doing the same thing?
My point is:
dataRows = DataTable.Select(filter) is better or
Passing paramters to stored procedure?
The datatable holds about 500-700 rows at any given time.
If I select one of the approaches the business logic will go into
respective layers.With dotnet in picture what would be a good approach

I'm at a complete loss on this problem. I'm using a DataColumn Expression with the DataTable Select method to return rows matching a data. Rows are returned on my Windows XP Professional computer at home, but no rows are found on the client's Windows 2000 computers.
I have checked the regional settings' date format on both machines, and they are identical. The expression used in both locations are identical, and the data used in both...

I posted this problem earlier and now have more information. I use the DataTable Select method to get find the most recent "LastModified" date in a table of similarly named files. I then use the resulting date and time to get the specific filename and path from the same DataTable.
The problem is that this worked fine on my Windows XP machine, but did not work on any of several Windows 2000 computers at the client's location. The Select...

I am using the Select method on a DataTable to return a DataRow
filter = (width LIKE '%width=\"%')
I am getting an exception saying my filter is invalid
I narrowed it down to the part that reads
if I eliminate this part it works.
Is there a way to accomplish what I'm tring to do?

Hi all
I have a small problem.
I have a datatable with 8 columns. But it is only data in 5 of the columns.

I Want to run trough the datatable and fill out the remaining data.

I am using VB.NET 2005 and Access database.
My program uses a timer that kicks in every 1 min to read from a database
and copy the dataset table to a datatable.
This database is in a class called clsStat.vb.
Then I pass this class to a thread.
Each thread will call a function inside the clsStat.vb to do a "Select" of
the datatable.
Every day around the same time this function that does the select of the
databale gets errors like so:...

Hi all
The application: VBA macro in which various Excel worksheets get printed, depending on the user's print selection via radio buttons.
The problem: As part of the macro, the print range has to be set, and the number of pages in the printed report echoed to the user, both of which depend on the relevant worksheet selected for printing. My coding for this is:
Print_Range = "A8:I" & ActiveCell.SpecialCells(xlLastCell).Row

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
