• Visual Studio 2008 (Pre-release) Generating two WCF services that use the same data contract

  Hi, I have two WCF Services than use the same DataContract. For generating ServiceClient I use svcutil tool. Every generated file contains the definition for my DataContract. In my case I have a conflict at compile time because two classes have the same name. Is the svcutil can do the “merge” between data contracts by not defining repeated elements How can I resolve this problem If you own both sides and want to share a class library with the data contract types in it for both services and clients, you can reference the assembly when you generate the proxy: svcutil /config:app.config /o:serviceproxy.cs /r:SharedTypes.dll http: //localhost:8000 If you want to use svcutil and create a servic ...Show All

• SQL Server Connection Issues To Report Services

  Hello all, I just installed the SQL 2k5 standard suite of services on a w2k3 enterprise edition server. All went well except for the connection to the reporting server. I get the error below. "No connection could be made because the target machine actively refused it" I can't seem to find any information on this error and have no clue where to even start. I've done 10+ installations of this software on various machines and have not encountered this error on any of them. I have uninstalled, then reinstalled the reporting services and still no solution. All connection attempts are being made on the actual server, not from a desktop. sp1 for sql 2k5 is also installed, if that helps. Windows Firewall is off. What w ...Show All

• Visual Studio 2008 (Pre-release) Text thumbnails & zoom

  Hi everyone out there. I wanted to know if there is native support in WPF for scaling a text file, so that can I quickly get a thumbnail with the general text structure, and even support for using that visual representation like a regular image (e.g. rotate it, fade it away, etc). Thx in advance, Alan No there isn't any kind of native support but you surely could load the text into a TextBlock, ScaleTransform and do anything you want to it even before turning it into an image/thumbnail. If you truly want an image you can use RenderTargetBitmap to take any visual and render to an image. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Newbie question

  Hi all, Having some issues building the default "My Space War" project in XNA. It builds fine but dies and gives me an error prompting me to send the information back to MS. Any ideas about why this might be Thanks! It could be that your graphics hardware can't support the shader levels necessary to run XNA, and in particular the shaders required by Spacewar. XNA requires at least Pixel shader 1.1 support, and Spacewar requires Pixel Shader 1.1 and Vertex Shader 1.1 support minimum. ...Show All

• Visual Studio 2008 (Pre-release) Customising Web Service Proxies

  Is there any advantage to upgrading to WCF over ASP.NET/WSE3.0 web services I am working in a situation where there a number of web services all returning the same common result structure. A client application even if it has a reference to the library containing the result structure, still produces across web servuices A, B, C A.Result, B.Result, C.Result.

• SQL Server Manually Inserting Data in DateTime Field

  Using Server Explorer in VB 2005, I am manually entering data in a table in a SQL Server 2005 Express database that includes a DateTime field.

Formats tried include all datetime formats (mmddyy, yymmdd, using dashes or slashes, enclosing in single quotes or pound signs). I would appreciate if someone could please give me an example that I can literally insert without error. Andrea, ...Show All

• Smart Device Development Lock application + screen-saver

  Hi all, How would I go about locking an application so that one would need to re-enter a username and password to gain entry again. I know thats very vague so here goes; Background: Im new to C# and developing a C# mobile app which displays confidential info to the user. Ideally, if the user has not tapped the screen for x minutes, the application should lock itself and not permit the user to see what it was displaying. This functionality should also be available as an icon incase the user voluntarily wants to lock the application. This are my thoughts on accomplishing this: Have a thread that monitors for taps and if the time between last tap exceeds a certain threshold, then the screen lock is called (Is this possible in C# ). If the use ...Show All

• .NET Development ActiveDirectory services VB.net 2005 obtain group membership for a patrticular user

  Hi, I'm trying to develop a program in Visual Basic.NET 2005 that will manage user accounts on remote computers. These computers are not part of a domain and do not have active directory running on them. They are running under their own workgroup and behind a firewall.. To workaround for the firewall I managed to develope a service app that resided on these computers and comunicated through IP and Port. Surely the port is open for me... Most of the functioanlities are working fine, like adding new user accounts, modifying, deleting, querying users,groups and so forth.. The problem I'm having is obtaining group membership for a particular user. The code is provided below: (the inCount is alwayz equal to zero) I'm not sure if I am doin ...Show All
