• SQL Server Creating referential integrity constraints

  Two ways to do this... Creating the constraints when creating the data model OR using SQL to use the 'reference' constraint. Does 2005 provide any other automated method of creating the Primary Key - to Foreign key constraints without writing the SQL to do this Thx Thank you for your answer, I didn't know that the GUI would do the things that you described.  That was what I was referring to.  I guess for me, the automated method would be that when you create a primary key, the create the foreign key in the 'create table' GUI, the foreign key constraint would be automatically created if the column names are the same.  Does this make sense   Maybe coffee is the answer.   As you mentioned above, there a ...Show All

• Visual Studio 2008 (Pre-release) mesh limitations

  Hi, just read a really interesting post here . It got me thinking about the limitations around net.P2P. That discussion was centred around a high number of messages in a network with few peers in the mesh. What kind of limitations are there in the number of nodes in a mesh Also, is there much difference in scale when using PNRP v a custom resolver regards, steven http://stevenR2.com Ravi I have a chat client implemented along the lines of the MSDN sample with a Custom PeerResolver. Can you point me to some documentation on how I can change this so that the clients may use PNRP - rather than use the PeerResolver. What change in behaviour can I expect if I transition from PeerResolver to PNRP I w ...Show All

• Visual Studio 2008 (Pre-release) Can a MessageContract be used with some other parameter in an Operation Contract?

  I tried using a string type with message contract, I am getting the following error. MessageContract parameters must be either a single input parameter or a return value. Is there any other way to use other types with MessageContract Thanks Sangeetha S So you're using a msgcontract attributed object as well as a string parameter for the operation Something like this: [OperationContract(Name = "ThisIsASimpleCallUsingMessageContract", Action = "urn:MessageContractTest/SimpleMessageContractCall", ReplyAction = "urn:MessageContractTest/SimpleMessageContractCallResponse")] ResponseMsg1 SimpleMessageContractCall(RequestMsg1 input, string blah); If yo ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. A Managed DirectX9 UserControl on a web application

  Hello, i've been searching the internet for a while, but cannot find proof that it is possible to user Managed DirectX functionality (embedded in a UserControl) in a C# Web applet. Has anyone come across some code or references that proof that it either can or cannot be done I guess that given the proper permissions it should even from whitin an embedded UserControl be possible to render 3D images, but before i spend hours and hours trying the impossible, i was wondering if someone else has already tried this... Please give a yell and thanks in advance, Peter Vrenken Yup, it's really too bad. I was hoping to try my hand at creating a single C# game, then just create a different build for the "demo" version that could be ...Show All

• Visual Studio Tools for Office Can't edit text in RichTextBox (VSTO 2005)

  Hi, When I add a RichTextBox to my Word document at Runtime, my textbox displays correctly my formated text. But if I try to change the format ot some text in the RichTextBox once Word is launched, nothing happens! How can I enable the formating of text in the RichTextBox Thanks, Claudia Hi Claudia, If you are using VSTO, the RichTextBox control isn't supported (which is why it is not enabled in the designer).  The Windows Forms RichTextBox control wraps the Win32 Rich Edit Control.  Unfortunately, Office uses a different version of the RichEdit control and WindowsForms does not behave properly if that version is loaded.

• Visual Studio 2008 (Pre-release) anonymous methods type inferring at assign time

  While assigning anonymous types like this: 118 Action < Rectangle , Color > DrawRectangle = delegate ( Rectangle r, Color c) 119 { ... it would be a really great to be able to rewrite it like this: 118 var DrawRectangle = delegate ( Rectangle r, Color c) 119 { Currently this will result in an error: error CS1811: Cannot infer local variable type from delegate or lambda expression The Action<A, B> delegate could reside within System namespace. Or is this already suggested and this just wont make it into the Orcas cheers, i guess this can be an answer for ur concern Yes, there is a difference between a lambda and a local of a delegate type. ...Show All

• Visual Studio Team System MSF Essentials book: natural vs. planned vs. externally facilitated checkpoints

  Hi all, What are natural checkpoints, planned checkpoints, and externally facilitated checkpoints I found them in MSF Essentials book, Chapter 3, p.36, which says: "MSF builds in natural checkpoints ... help a team reflect and assess successful and not-so-successful aspects of a project. Planned checkpoints throughout the MSF Governance Model help teams to make midcourse corrections... MSF emphasizes the importance of organizational-level learning from project outcomes by recommending externally facilitated project checkpoints and post-project reviews."

• Visual Studio 2008 (Pre-release) WCF Authentication - Point me in the right direction pls

  Greetings, I am writing a c# 2005, smart client application and have decided to use WCF as the transport layer. Having previously only used HTTPS ASMX based web services for such a distributed style application I am quite new to some of the concepts involving how to secure WCF. Perhaps someone can recommend the best approach to my scenario, the smart client will be public web based and ClickOnce updateable, therefore no Windows usernames or groups will be used, each smart client user has a set of 4 custom credentials required in order to logon to the WCF service, these credentials would be checked with custom code which looks in a back end SQL database. In the past I have kept it pretty simple and used a custom single Logon me ...Show All

• Visual Studio Express Editions Dynamic help doesn't work in cpuid.c, but works in cpuid.h and test.cpp???

  I download it from http://download.microsoft.com/download/B/A/D/BADA8219-9761-498D-85B4-4565C28F4DB8/crt/cpuid.zip.exe I found that in "cpuid.c", dynamic help shows "No links are available for the current selection", and in "cpuid.h" and "test.cpp" dynamic help is okey. And I can also build and run the program. But why Dynamic help doesn't work in cpuid.c Need help. To build that sample, you need to change the current configuration. Build + Configuration Manager, change Platform from Titanium to Win32. You can't expect dynamic help to give you any info on cpuid.c; it is filled with assembly code and other low-level stuff.
