• Visual Basic Visual Studio 2005 Pro - Academic Version

  I'm thinking about ordering VS Pro from school, but they can't give me details (it's not kept in stock)... does anyone have the academic version and does it require internet regsitration/activation Some people are saying yes, others are saying no. Thanks Any mention of off topic item was evidence and reasoning for this on-topic question. When Ms stops supporting these activated software... don't they become ExpireWare The emphasis on pushing users to upgrade to newer versions ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. My First Project

  Anyone having fun with XNA I have my tetris clone coming along quite nicely.. http://str8dog.shackspace.com/NotmyTetris.png Right now its based on fixed time steps, I am struggling to wrap my head around how to let the game run real time and get the blocks to not fly down the screen. The spacewar example is awesome for picking up how to do various bits like sound, texture management and user input. Hell some of the classes I just swiped outright they were so easy to use. What have you folks been able to do so far NotMyself wrote: Thanks to Mitch for answering my question on another message board. My tetris rocks!

• SQL Server Checking Out Data to Client Users

  I'm trying to resolve an issue that I've run into in my current system. I have about 10 clients accessing a SQL Server several times per minute (every 10-20 seconds). To have an individual find the next record, I follow the following process: 1. Select the value of the next record in the database to be checked out. 2. Update the record to show that it is checked out to the user. 3. Select the data in the record to display to the user. 3. Update the record to show any changes and to check the record back in after the user edits it. My issue is that clients can execute at the same time. Right now, with just SQL statements, two clients can get the same value in step #1. That makes them select the same record for editing. Can I use T- ...Show All

• Visual Studio 2008 (Pre-release) using DefaultStyleKeyProperty in a derived class?

  Hi there, I've created a CustomControl which is derived from HeaderedContentControl. I've also created a default Style in the application resources (the CustomControl is *not* in a control library) In the static contructor of my control I'm calling DefaultStyleKeyProperty.OverrideMetadata(typeof(MyControl), new FrameworkPropertyMetadata(typeof(MyControl))); All works fine until I derive from that custom control. The second derived class dosen't use the default style of its base class (which is defined with DefaultStyleKeyProperty...) Is there a way that the second derived class uses the style of the first derived one greetings cheesenhomer Hi Mike, thanks for your answers, but none of the two hints work ...Show All

• Visual Studio 2008 (Pre-release) Problems with Callbacks

  I'm trying to create a WCF service that utilizes a duplex contract. The way I would like this to work is as follows: The client connects on a WSDualHttpChannel to the service and calls a method "BeginSearch" The service intiates a search on a new thread, which can take several minutes to complete Once the search is complete, the service initiates a callback method (SearchComplete) passing in the search results as a parameter. In the BeginSearch method I store the results of a 'OperationContext.Current.GetCallbackChannel<>()' call, but when I attempt to call this method nothing happens, no exceptions, no nothing. If I call the callback from within the BeginSearch method, it works fine. I'm assuming this has ...Show All

• Windows Search Technologies WDS won't index my Outlook files

  WDS was working fine - no problems - and then stopped indexing my Outlook files - about 2-3 weeks ago ( ). I am on XP Pro x64 edition - MS Outlook 2003 (SP2) - and WDS 3.0 ( which I believe is required for x64).

• Visual Studio Team System FxCop 1.35 skipping Structs

  While analyzing the NodeType the FxCop 1.35 is skipping the Struct which itself is a NodeType. I tried the following code while overriding the Check(NodeType) but still the structs are not getting trapped public override ProblemCollection Check(TypeNode type) { if(type == null) { return null; } switch (type.NodeType) { case NodeType.Class: return Check((Class)type); case NodeType.Interface: return Check((Interface)type); case NodeType.EnumNode: return Check((EnumNode)type); case NodeType.Struct: return Check((Struct)type); } return base.Check(type); } I tried one workaround for this by overriding the Check(Module) method and checking for each type. There I can trap the Structs. But problem with this ...Show All

• Visual C# Why string is a reference type?

  I don't understand it. System.String hola = "tal"; System.String hola2; hola2 = "talycual"; Debug.Print(hola2); hola2 = hola; hola = "___"; Debug.Print(hola2); And the output is: talycual tal If string is a reference type ... the output must be at the last line : ____, but 'hola2' has a copy of 'hola' . I understand differences between struct and class, and because is struc a value type and because is class a reference type but ... i don't understand because is string a reference type Regards. >> C = A, there is nothing in this operation simular to normal class behavior.

• Microsoft ISV Community Center Forums Visual Basic for Excel

  I have several hidden workbooks loaded at startup that contain excel macros used to modify certain special workbooks. I also have a number of modules that are universal and contain procedures and functions I'd like to use in any project that I load. The file containing common modules is S.XLS and special workbooks C.XLS and D.XLS VB for Excel recognizes each sheet as a project. As I read the on-line help, to refer to procedure TestSub in module MySubs in Project S.XLS from procedures in project C.XLS the code would be: sub UseTestSub [S.XLS].[MySubs].TestSub end sub This produces an error that the file doesn't exist. Is there a correct way to access SUBs and Functions from another project Should I be doing something diff ...Show All

• Visual Studio SKU011.CAB solution

  Go into Registry Editor (Start, Run, "regedit"). Go to HKEY_LOCAL_MACHINE, Software, Microsoft, Office, 11.0, Delivery. There should be only 1 directory under Delivery, which is your DownloadCode (mine was 90000409-6000-11D3-8CFE-0150048383C9). Select that directory. On the right side of the screen, right-click on CDCache. Change the value to 0. honestly works with out a hitch. Hi , Problem SKU011.cab after an auto MSupdate, and among others things it invited me to install MS Explorer 7. Sorrily I did it.

• SQL Server Client Render broken after upgrade to Win2K3 Enterprise from Standard

  First off, any suggestions are welcome here as we're lost. We have a farm of 2 Win2k3 (standard) servers that had a couple GB of RAM. We then installed 16GB of RAM and upgraded to Win2k3 Enterprise to handle the upgrade. Prior to the OS upgrade our reports rendered as expected. Post upgrade, they do not. Some background on how we render...we open a PDF rendering of a report in a popup via JavaScript. Also, we have 3 environments running the same code base. The only difference between the 3 is that one environment is the one we upgraded to Win2k3 Enterprise. Again, any suggestions are much appreciated!
