• Game Technologies: DirectX, XNA, XACT, etc. Is XBox Live / new DirectShow replacement coming to the PC still?

  According to this website near the bottom, ( http://www.toymaker.info/Games/html/gdce_-_xna.html ), XBox Live is heading its way to the PC which I think is really neat. It also says that DirectShow is getting a new media SDK. I'm curious, since it was posted a while ago, is this still in effect It would be nice to see new these tools come out so I don't have to rely on third-party tools and SDKs. Thanks in advanced! Please post DirectShow questions on the DirectShow forum . Regarding Live services on Windows: Stay tuned. ...Show All

• Visual Studio Tools for Office VSTO 2005 Install before VS 2005

  If I installed VSTO 2005 and later want to install VS 2005 Professional will there be a problem or should I uninstall VSTO 2005 first. In other words do I have to install VS before VSTO for the IDES to merge properly I have done exactly the opposite of what you say: first installed VS 2005 Pro and then installed VSTO. It works just fine. It seems that the IDE loads all the available components, even if they don't belong to the same installation process. Remember, VS 2005 Pro doesn't include VSTO, so uninstalling VSTO and installing VS Pro will eliminate the option to create Office projects. One thing is for sure, the "add or remove programs" list will still show both versions (in full size) if you install one over the ...Show All

• Windows Forms Part of user control hidden inside groupbox

  Hello all, I've created a control derived from UserControl class. The purpose of the control is to simulate the DateTimePicker control in windows form but I need some domain-specific behaviour. I had a masked text box to have the date and a little button beside it. When you press the button it expands the control area and show a MonthCalendar from where you can choose dates etc. Now everything was fine, I was very happy with the outcom until... I droped my user control in a GroupBox control in my form. The height of the GroupBox is small, so when I press the little button, it hides my month control. I noticed that the windows forms' DateTimePicker control does not show this behaviour-problem even if it is inside a GroupBox of limited ...Show All

• SQL Server Thank you for PIVOT and UNPIVOT!!!

  I just used PIVOT and UNPIVOT to save myself what would have been close to an extra page of code. Thank you Microsoft! I'm sorry, but I just have to say if you have columns and rows to transpose in SQL 2005, learn about and use these functions. They are lifesavers. It is really nice to have some usable functionality from Analysis Services in T-SQL. This definitely falls on my list of favorite enhancements right after RANK/DENSE_RANK/NTILE/ROWNUMBER. ...Show All

• SQL Server Threat due to SQL Injection

  I have gone through a terrible situation a week ago. One website was working fine since couple of years and suddenly it was hacked. I checked the entire code in all the pages and it was not at all modified. When I checked the database, I found that javascript was inserted in it. As soon as a recordset was displaying it, javascript redirected that page to the hacker's site.. This was the mechanism was used by hacker. Which database can be more secure in such situations Nishith Shah Nishith Shah wrote: Thanx a lot buddy. But still I am not able to solve the issue.

• SQL Server RS2005 Date parameter - JScript error

  I have a RS2005 report that was deployed to a ReportServer and has been running for over 1 month. I personally have not run this report in the past month, however, today when I tried to run it I got an error trying to select a date parameter. I can't paste samples of the windows displayed, so I'll do my best to explain. When I click on the report, it goes to the View window and displays 2 date parameter fields. When I click the icon next to one of the parameter fields, I get an error window that says A Runtime Error has occurred. Do you wish to Debug Line: 383 Error: 'resultfield.id' is null or not an object I click Yes and get a VS Just-in-Time Debugger window, where I choose New instance of VS 20 ...Show All

• Visual Basic USB driveletter

  Hello everybody, The last two day's i'm trying to enum my USB devices and the drive letter. With WMI i'm able to get a hole lot of information about USB, but i can't make the link to the associated drive letter. Does anybody have a hint how to accomplisch this With regards, Jurgen Careful with that approach as you can assign a drive letter manually, I for instance move the CD to Z:. For CD use if d.drivetype = drivetype.cdrom. Good luck, I guess you may have to use several methods to get to the right information you need. I know with my iPod code it only really works at identifying the iPod because the iPod has a known directory structure, but if that changed... If I come up with something else I will l ...Show All

• Visual Studio 2008 (Pre-release) Loosely coupled servers: Datacontracts and proxy question

  Hello All. Would you please take a look at a design problem I have with WCF. We use a component based architecture and are looking to use WCF in a server to server environment. One server is the data provider and 3 identical servers are the consumers. We are struggling to keep the servers loosely coupled. Therefore the Provider has a simple service contract, which a consumer calls on startup to get initial data: [ServiceContract( Name = "PriceProvider", Namespace = " http://www.mw.com ")] public interface IPriceProvider { [OperationContract(IsOneWay = false)] List<Price> RequestAllPrices(); } Every minute we want to push changes (via timer) to the consumers. Therefore the consumer ...Show All

• SQL Server Search functionality in reporting services

  I am creating a simple report in reporting services. It contains basic fields such as first_name, last_name, ID#, location. Is there a way to create a search/find function that lets me input a field and it will find the results from any column I think I can figure out how to search by 1 single column but want the user to input one thing and search multiple fields. For further clarification...if they know the last_name, but want the id#, they can search for last name and get all the columns for the particular search....same would work for, if they know the ID#, but want the last_name, they could search for ID# and get all columns in the result. Is this possible I am not sure this is ...Show All

• Visual Studio Team System Cannot pass a GCHandle across AppDomains using unit testing.

  Got a manage C++ class in a class library that uses unmanaged C++ lib. The managed C++ class handles callbacks from the unmanage C++ lib by a delegate "gcroot<MessageDelegate^> m_MessageDelegate". To invoke the delegate I use the call "m_MessageDelegate->Invoke(nMsgId);". This works without any problem when running applications using this class library but when testing the class library using unit testing I got the error "Cannot pass a GCHandle across AppDomains" when I invoke the delegate. When running Unit Tests by default we create an App Domain per test assembly. It seems that MC++ has its own app domain for unmanaged code and gcroot does not allow marshaling across app domains.

• Visual Studio 2008 (Pre-release) Dynamic Queries and Nullable Fields

  Hi All, I have been playing around with creating dynamic queries using DLINQ/LINQ and whilst the functionality is great I have run into a problem. It revolves around creating a query using an existing object with nullable fields. Essentially I am trying to create a query that will check for duplicate values in the DB based upon an object I have in memory. The problem arrises when I try to construct the expression: object value = MyContact.GetType().GetProperty("Myproperty").GetValue(MyContact,null) // value now contains a system.int, but Myproperty is defined as system.nullable(System.int). If I then try and do this: IQueryable q = EntityInfo.QueryableTable; PropertyInfo Prop = MyCustomer.GetType().GetPrope ...Show All
