• SQL Server SQL Express in VC++ 6.0

  I apologize if I'm not posting this to the correct forum, please bear with me. I am a newbie to SQL Express. I am working with a product that was built back in the Borland days but was upgraded to Visual Studio C++ 6.0. I currently use mySQL, but need to upgrade to SQL Express 2005. Could anyone please tell me if it is possible to use SQL Express with VS C++6.0, or even point me to some documentation that would give me some light on the topic Many thanks! Hi Angie, Yes it's possible, you should be able to connect to the SQL Express database using the same method you currently connect to MySQL, only using a SQL Server connection string. Most people recommend http://www.connectionstrings.com to get ...Show All

• Visual Studio Team System SCM plan for dependent projects in TFS

  Despite the historical odds, this might be a dumb question. I'm working with TFS and trying to set up a series of dependent projects (e.g. Enterprise Library -> NUnit). I'm wrestling with how to approach version control. In workspaces that modify NUnit, Enterprise Library wouldn't be accessed at all. In workspaces that modify Enterprise Library, NUnit would be accessed but not modified (ideally a given release of NUnit would be accessed read-only). In workspaces that modify Enterprise Library, how can TFS help me communicate to developers that they should not get the latest from the NUnit project, but that they should get a labelled version. I also believe that I might be following the wrong track altogether and that the bes ...Show All

• Software Development for Windows Vista Alert ! Vista Explorer only supports 16'383 File Copy Operations !!!

  after copying about 16'383 files you must re-boot Vista, because Vista Explorer begins making nonsense. Try it that way: make a new directory somewhere on your harddisk open Notepad and immediatley save in your new directory (the Notpad .txt file can be empty or not) select that saved Notepad .txt file with Vista Explorer do exactly the following 16 times - it will take longer and loger any time of course (up to minutes in the last cycle): ctrl-a    ctrl-c    ctrl-v   (Select all files in the directory, copy them, paste them) === I'm shure you will get a message " ... out of memory ... " - and you have to reboot for a stable system. And your new directory will have less the ...Show All

• Visual Studio ViewState error

  I am repeatedly getting an error message when running my project: ASP.NET ViewState has been disabled. The Report Viewer control requires that ViewState be enabled. I have a single Master Page with a single content area. The ReportViewer control is in the corresponding content area of a second .aspx page. There are no other asp.net controls in either page. EnableViewState is set to "true" in Web.config, the Master page and the Default.aspx content page. I just want it to work. Am I missing a ViewState setting somewhere I've searched the forums and the web but have found nothing that says it's not possible to view a report through a Master / child page setup, so I naively assume it can be done. Running the report ...Show All

• Audio and Video Development Scaling with DXVA2.0

  Hi, I’m currently studying the DXVA2.0 device management and video processing and I wonder if you could help me with the following trouble: I’m want to build a MFT who doe’s video processing on video source, one of the features I want to offer is the ability to use the hardware scaling capabilities instead of my software algorithms. Therefore, I came up with some basic questions: 1. When setting the video position by the IMFVideoDisplayControl interface to a larger destination rectangle then the source rectangle – how can I ensure that the resizing is done by the hardware and not software 2. Is there a way to implement scaling using the IDirectXVideoProcessor::Video ProcessBlt in my MFT so I could actually ...Show All

• .NET Development System.Runtime.Remoting questions

  Trying to compile a file ( RealProxy.cs ) at url http://www.123aspx.com/Rotor/RotorSrc.aspx rot=41579 I ran into a number of problems, the major of them illustrated by error messages: 'System.Runtime.Remoting.Messaging.Message' is inaccessible due to its protection level. and 'System.Runtime.Remoting.Identity' is inaccessible due to its protection level. Before this file I tried a few others in a similar vein and the Identity object got the same reception over there as well. Also this appear to be an insurmountable problem: Inconsistent accessibility: parameter type 'System.Runtime.Remoting.Messaging.Message' is less accessible than method 'System.Runtime.Remoting.Proxies.RealProxy.EndInvokeHelper(System.Runtime.Remoting.Messagin ...Show All

• Visual Studio 2008 (Pre-release) STS Sample "Federated Security" on wcf.netfx3.com

  Hi, I've got this Federated Security sample running ( http://wcf.netfx3.com/files/folders/authorization/entry1954.aspx ) and I would like to make an additional client application. This second client is a copy of the "Client" application included in the sample however this copy will be running in-house "at Woodgrove" rather than "at Fabrikam". This copy needs to work when the Fabrikam STS is unreachable (not running) When I use SvcUtil, I get a config file that is for running a client from Fabrikam and I'm not sure how to generate (or change) the file to get the "at woodgrove" behavior. "This Woodgrove client should not need to contact the Fabrikam STS i ...Show All

• Visual Studio Team System Adding Team Foundation Licensed Users to TFS Workgroup Edition -- Help...

  I just spent several hours installing a fresh copy of TFS Workgroup Edition on its own box (as single server deployment). In addition, I already had VS Team Suite on a second box. Both installations have SP1 installed on them and work on their own. However, I cannot seem to add users from my 2nd box to the list of Team Foundation Licensed Users on my 1st box, where, when I click Team | Team Foundation Server Settings | Group Membership | [Server]\Team Foundation Licensed Users Properties Windows User or Group Add... ... the "Locations" button only enables me to see the TFS box itself.
