display images from SQL Server image across intranet using ado.net filestream object
i recently attended an MCPD boot camp where they taught me to access and store images using SQL Server and the filestream object. Previously i had (sensibly) used a file server and impersonation to copy files.
Uploading works fine. Viewing works fine in debug so i rolled out an app in my work where the pics are uploaded and viewed across the intranet.
to my horror i realised (too late!) that whilst it works fine in debug, it does not work when published. now no one but me can access these pics and it is a night mare.
the only documentation i have found ...How to call or retrieve fields from sql and display in table without using ADO.net, I'm using a dynamic link library....Is the coding different?

The easy way to do this is with the use of a data bound grid. The Grid can be customised to look and feel you like. You will need to add a data adapter to your page and a grid. When you setup the data adapter you will nee...Does .NET map calls for ADO to ADO.NET?
Hello,We are trying to troubleshoot some DB problems from COM objects that call ADO. I heard that when ADO is loaded inside of a COM object by a .NET app, that .NET intercepts the call and re-maps those calls over to ADO.NET. This seems untrue to me, given the nature of ADO.NET being a totally separate technology.Does anyone know for sure whether this does or does not occur?The problem we are seeing is actually almost identical in symptoms to this:http://support.microsoft.com/default.aspx/kb/230101"FIX: Data Queries Sporadically Return Empty Recordsets" Literally, this is what...Innovation to ADO.NET
Matisse Software Inc. provides its native ADO.NET Data provider for Matisse 6.0, the Database for .NET. Matisse Software has pushed the envelope of Microsoft ADO.NET architecture and extended it into a powerful Object Access Services component for .NET.
Matisse’s extension of ADO.NET demonstrates that ADO.NET can evolve beyond the Microsoft architecture to benefit .NET developers. Unlike the standard ADO.NET data provider, which returns data in a table format to integrate seamlessly with relational products, Matisse has extended the ADO.NET architecture to return data in an object format....ADO.NET table fields pass to a VB.NET variable

I am writing a database interface and I would like to know whether a
VB6 interface using ADO or a VB.NET interface using ADO.NET would be
faster in terms of just performing database operations. Is there an
explanation for this, and what is the magnitude of the difference?
Thanks in advance!...ado.net or/and datawindow.net
Can datawindow.net work with Sybase's ado.net or are they not compatible
with each other.
We have two separate groups of developers, one group develops web apps using
ASE as the back end for the data, so they use a combination of Visual Studio
..NET and Sybase's ado.net to do their work. We have another group that
develops client/server apps using Powerbuilder, but since 80% of their work
is in writting reports using Powerbuilder, I was wondering if they could use
a combination of datawindow.net and ado.net to put make these reports

It is available in the ASE SDK for windows or the PC Client CDRom included

Hello folks. What is the best way to display in a Label one column from a selected row in a GridView? The gridView is populated manually in the code behind, and it displays the data. The column in question is not one of the bound columns in the gridView, but is part of the dataSet (ie, the gridView shows columns 1-3, but I want to display column4 in a label. I started on code to identify the key, but not sure where to go from there.

...Cannot connect to SQL Server database using ado.net after IP address has changed
I wasn't able to connect to my SQL server 2000 database (which reside in the network in a windows 2003 server) after the IP address of the server has changed and the server is shut down, moved and re-started.
I was able to connect to this server by using ADO using VB. I was able to register this server in my EM and was able to create ODBC connection. Just when using ADO.NET, I wasn't able to connect. Any ideas? Will there be any caching within ADO.NET still pointing to the old IP address?
Thank you for all the help in advance.
