• SQL Server How to use both auto generated id and a guid in database

  I downloaded the AdventureWorks OLTP Schema and am trying to use some of the design concepts that are used in this example but I don’t quite understand some things. First there is a column named rowguid, at the moment I assume that this is a GUID. If this is wrong most likely my next question will make no sense. Second if that is indeed a guid all the tables have another id; example would be Employee table would have employeeid and rowguid, why do this My best guess is that you would use the guid to easily insert (linked/sync) data into multiple tables without needing to retrieve the id from the table that was first input into. My scenario would be inserting an employee; to insert an employee you need to create a row in t ...Show All

• .NET Development Ping, packets, TTL and losses

  I have done a fairly good search and had found some good code that I was able to use. I have been programming in VB only for a while, thanks to the Express 2005. Well a good friend and I are working on a progam that sends requests over the network. What we want to do is first list all the computer on the network, which isn't that many. We want to to pull the IP of the connected computer and maybe the MAC address and computer name. We also want to send a ping and get the losses. I'm new to the system.net but have a lot of work with IOFile systems. Can any one help me with this in VB only EDIT: If some one could get me started on perhaps creating something similar to the Windows ping.exe program. I would like to start by sending the packets ...Show All

• Visual Basic ? Textbox

  I am probably doing this wrong BUT I put a form together with the following: Datagrid - all read-only and most of the cells hidden for a reason 3 textboxes from the same datasource as the datagrid Now when I select a record from the datagrid, the textboxes change accordingly to match the record that was selected in the datagrid, I can change a value in the textbox and update the datasource and it changes(everythings fine) but when I change the visible property to false, I run into a little snag. I cannot reference the textboxes content. I change change it back and its fine. How can you hide the textbox I changed the color of the box and text to the background color and you can still see the text. I also tri ...Show All

• Visual Studio 2008 (Pre-release) Videostream

  Hi all. Been looking around with the aim of writing an app that can both preview and stream webcam video, but appear to have fallen at the first hurdle. All the information I can find seems to be older, using either native calls or DirectShow to perform this, but I've been told that the framework now supports using a WebCam. Anyone got any information on how to use a webcam preview, and maybe how to go about streaming it over a network Thanks! I think implementing this as you describe would be very complex. A fun weekend project sounds optimistic. Even if you did, you would have several limitations: 1. Lack of videocard acceleration (alternatively you could do the video processing on the card and t ...Show All

• Windows Forms Membership and Personalisation in Windows Forms

  Hi, Can I use the Membership and personalisation feature of ASP.Net 2.0 in Windows Form based applications or is there a different way to achieve the same Thanks Sai Yes, I do for an application the simpliest method is to setup a webservice and do your authentication against the webservice. i.e Webservice expose function public bool Login(string username,string password) So you would call you webservice app instead of calling a bus layer class. The cool thing about this for me is that I can then keep on username and login for extranet services and internal windows app. You should use SSL on the webservice though to keep things secure. The other way I believe is that you could use the ...Show All

• Visual Studio Generate one chm from multiple dlls and their xml documentations?

  Sorry if this has been asked/answered already. I quickly browsed through the threads but didn't find any that would answer this in detail. Let's say I have a Logic.dll and an Elements.dll. I also have a Logic.xml and an Elements.xml which contain the vs2005 generated xml documentation. Logic has the, um, well, logic and Elements contains the property classes that could be the input/output parameters of the methods in the Logic.dll. They are not in the same vs solution or project. Logic.dll is referencing to Elements.dll as a dll reference. Is it possible to generate a single chm from those two dlls and their comments with Sandcastle I tried to use the Mrefbuilder like so: " MRefBuilder Logic.dll /dep:[path_to_references]\b ...Show All

• Visual Studio Express Editions Files with same manifest resource name
