• Visual Studio 2008 (Pre-release) Client callback with a facade

  I need some help with the following design pattern. It is a basic publish/subscribe pattern with a facade. The subcriber is a Wcf windows app. The publisher and the facade are both Wcf services. The subscriber communicates with the facade via Http. The facade forwards the request to the publisher via netMsmq. The publisher processes the request and sends update messages directly to the subscriber (it does not go back via the facade). The publisher continues to push updates to the consumer until told otherwise. My question is, what is the best way to pass a client callback to the publisher In other words a duplex MEX via an intermediary. I have checked out the router sample but it looks a bit complicated.

• SQL Server Problems Creating Database on SQL Srvr. 2005 Ent. Edtn.

  Posted - 12/17/2006 : 07:23:22 Hi Joey, Thanks for your response. I did have those drives available (e,f,g) and the subfolders required. However, I created them as shared folders mapped to respective volumes. I think the problem there is the way the SQL Server permissions. I tried as you suggested, with just the C: drive and it worked no problem. I don't know why SQL can't find the volumes though... will have to investigate that further. Thanks, Will ...Show All

• Smart Device Development Cannot display local XML files in emulator

  Using IE in the Pocket PC 2003 SE Emulator, I can view XML files over the Web (i.e. via a URL) but not local XML files (i.e. file:\\...) that are on the device's storage card (i.e. a folder on the host machine). Is this a limitation of the emulator, are local XML files displayed properly in actual devices, or I am doing some wrong But IE on the real device does display the local XML files, right (my problem isn't manipulating XML files, but whether the Web Browser component in my app will be able to display the contents of XML files -- because that's what my app does, it converts Fast Infoset files to XML on the fly and displays the XML file to the user) ...Show All

• Visual C# private fields, public properties...why??

  Why is it preferred to have private fields and use public properties to access and/or set the variable values Some of the books i have read do explain why...but only vaguely. Does anyboday know the real 'life threatening' type reason why we should do things this way Thanks well there is that too in a sense but its just best practice/better design. Say you are working on a large project between you and your developers. What happens if a developer accidently, without realizing, sets a value of a property of a class to something which you do not want, or which can cause severe problems during your execution of your application, such as calculation or changing a bool value to true inste ...Show All

• Architecture Trying to figure out the max. number of concurrent users/requests for a single server.

  I have set the number of maxiothread and other settings in the machine.config as MS has suggested for heavy loads. I am running on Dual CPU's Dual Core servers with 16 GB of RAM. I am running load test using 3 sites going to different application pools - load balanced. I get up to around 250 users and I start to see response delays but can't figure out what is causing them. All 3 servers, web/app and db are running under 30% cpu and under 10% memory.

• .NET Development XmlDocument

  Hi, I need to create an XML document in VB.NET to include the type of the element as this will be used by another process once I have created and exported the XML file e.g. <IDField type="asn1:INTEGER">3</IDField> Is it possible to do this, I have looked at XmlTextWriter as a method for creating the XML document within VB, but can't see an option to include this information. If I load in an XML document that already has this information in it then it is retained internally and is present when I export the document again. Any help appreciated, Dave What you have in your XML sample is simply an element with name IDField which has one attribute that has the name type and the value asn1:INTEGER. So with XmlTextWr ...Show All

• Visual Studio Express Editions Express edition vs. "the real thing"

  Hi folks, I am currently working on a program that I intend to use at our company. Since VBE is free, I thought I start with that to see if I can manage to get the job done. Now it appears that it might work, so I think about purchasing the VB Studio 2005 package (VS). I bought Evangelos Petroutsos book "Visual Basic 2005" (recommended!), and from what I can see everything applies to both the VB part of VS, and to the VBE edition. I have a few questions however, just to make sure: - can any solution written in |the Express edition be imported / opened in VS or does it need to be re-written - will an application compiled in VS run faster (more optimized code) - is there anything else different that I should know Greetings, Th ...Show All
