• Visual Studio 2008 (Pre-release) cross compatability of dlinq based assemblies

  Hi there, we're looking at using DLINQ as a DAL externally referenced in a seperate assembly from the mail application. The main app being written in vanilla C# 2.0 and the DAL compiled using the DLINQ specific compiler, leading me to my question: Can I add a DLINQ compiled assembly as a reference to a c# 2.0 project I think I can but it'd be nice to get some clarification..... thanks in advance! Tom You may need to include the LINQ/DLINQ assemblies that were referenced in your application for the inheritance tree, but otherwise, you should be able to work with the 3.0 built assemblies in a 2.0 client project. Most of the LINQ magic is syntactic sugar built directly on top of the 2.0 framework. The Lamb ...Show All

• Visual C++ I know VC++ 2005 .NET. Should I trash it?

  Before Studio 2003 came out I would use VB for my GUI front ends. Now, VC++ is just as powerful in the GUI department as any .NET language. So, I thought I could say ‘audios’ to VB, and stick with my multi-platform C++. But then at the same time C/C++ developers on Linux have grown to become a growing threat to Windows, and so I see Microsoft backing away from C++ as evidenced from its developer certifications (all must use non-standard, mono-platform languages). Certainly, the language is still evolving at MS, but its probably just momentum. So paradoxically, Im thinking now I should say ‘audios’ to C++ instead of VB. Or, should I just replace C++ with C# Thanks for any advice! The drop of C++ certificat ...Show All

• Visual Studio Express Editions Problem with TableAdaptor & Datagrid view

  Hello All, I have been working on an app that needs to be able to make a change to existing data in an Access database. I can add a new row but I can not make changes to that row using my own code. So I decided to try the datagrid method and dragged the DataGrid component over to a new form within my application. This of course should add all of the necessary elements to be able to make changes, deletions etc to a database. However, when I run the app and attemp to make changes to the database via this datagrid view I get the following error. Update requires a valid UpdateCommand when passed DataRow collection with modified rows. One of the things I noticed is that the properties for the TableAdaptor does not have a command for Up ...Show All

• Visual C++ Error: Stack corruption around the variable 'tm'

  Hi, I have a win32 based application written in VC6. However, when I port it to VC2005 express edition, i get runtime check errors in the following way. Run-Time Check Failure #2 - Stack around the variable 'tm' was corrupted Run-Time Check Failure #2 - Stack around the variable 'lpText' was corrupted. The application works perfectly in VC6. As this has been tested using profiling tools such as Numega Bounds checker. Only on .NET versions 2003 and 2005, i get above such error.

• Software Development for Windows Vista Problem coming in GetIfTable() function used in Windows Vista

  Hello, We are now testing our applicaion software on Microsoft Window Vista with Visual Studio 2005 And we have a function that gets the Mac address of the installation PC specifically the mac address of the LAN Ethernet card. I am using the IP helper (GetIFTable function) to get the list of Network Adapter and filter only Ethernet type to get LAN mac address(shown in ipconfig/all). The original function works fine in Windows 2K and XP(SP2). Invistigating it, the problem is MIB-II interface table which I received from IP helper function GetIfTable() has many entries for ethernet adapter, one with the same name as ethernet adapter, other with QOS appended to it, and also WAN ethernet adapter so on and so forth. The list comp ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Components w/ different timings?

  I like the model of specifying Game.TargetElapsedTime and responding to update events, but can I conrtol this on multiple components For example, let's say that I want to randomize the weather conditions in my game. I'd like this to update every minute or so. On the other hand, some things need to update every frame (ike controller input or sprites positions). One way to handle this would be to simply have methods like UpdateWeather() , and UpdateSprites() and so on, and have multiple if/then blocks in my main Update() code that determine whether it's time to call one of the other update methods. However, it'd be nice to offload this monitoring somehow so I could just declare in my init code how often certain components get updated. A ...Show All

  Hi,        Here is the long due sample for writing custom activity designers utilizing the freeform activitydesigner. This is still a very crude sample, so we will try to post improved versions from time to time.  Thanks to Arjun for the Executors and Validators.

• Visual Studio Team System Data Compare against a blank db or project

  Why is it that I can do a schema comparison against my project but I can't do a data comparison against the same project (The option isn't even available in the data comparison wizard.) I could easily be missing something since I'm quite new to this. Thanks for any info or help on this. Sincerely, Steve Mayhugh My bad it should read Taking this logic, it seems totally valid that data compare is not enabled for database to project comparison ...Show All

• Visual C++ Psychic Windows

  I am asking this question because it is related to my Post-Graduation course. It has been mentioned in the "Windows Programming with VC++" paper. The topic they have mentioned is "Psychic Windows". So, what exactly is that And howz that related to Windows platform or VC++ programming I searched a number of books from Microsoft Press & online too. But could not find anything useful. Can anyone around here help me with the topic The University Servers have been down for quite some time. So, I decided to provide a copy of the Syallabus I have. Well, the copy has been uploaded at: http://rapidshare.com/files/1013621/Syllabus.htm "Psychic Windows" has been mentioned in the " MCA-305 WINDOWS PROGRAMMING ...Show All

• SQL Server Using AMO to manipulate cube calculations

  We have a cube with a bunch of calculated measures that were defined using BI Studio. I'm now looking at using AMO to manipulate the calculations (enumerate, modify, add, remove, etc). But what I see in the AMO object model is one MdxScript object with one Command object. That Command object has one very large Text property, with all of the calculated measure definitions munged together in one giant string. Not too easy to manipulate programmatically. Is there anything that I can do to make this easier to deal with Or is this just the nature of the beast with calculations, and I need to munge around in the giant script Is there some best practice (splitting things into multiple scripts, for example) that we missed I noticed that the AW dat ...Show All

• Visual Basic Right-clicking my app icon in the taskbar does NOT consistently bring up a Control Box Menu

  I am writing a Visual Basic 2005 application using Visual Studio 2005 (90-day trial version). My application displays a slideshow, moving from image to image by using a Timer. I have the timer set to a 100ms interval, and I use date/time comparison to decide whether to swap images. When the image swap occurs, I reduce opacity to 0, switch the BackgroundImage of my form, and raise opacity to 1. It seems like my application works fine, until I set FormBorderStyle to None. When I do that, and while the application is being displayed (i.e. WindowState = Normal), I right-click the program button in the taskbar. I can only get the Control Menu to display when the image is being changed. During the timer interval, when I would expect windo ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. 1280x720 For Space War??!?!?

  OK... maybe it's just me but... The SpaceWar starter kit requires that the machine is capable of 3D display of 1280x720 isn't that a little bit big for normal users For an actual game, yes that would be appropraite for the 360 and high end systems. But SpaceWar is supposed to be a starter kit demonstration for students and beginner programmers to learn with, most normal notebooks which students around my area carry only supports displays of up to 1024x720 and with rudimentary graphics acceleration. The aging Toshiba M200 which I use have a GeforceFX but it also can't muster up a 3D display of 1280x720 (code died trying to run). I changed the code so that the window would be smaller, but the whole game seems to be hard coded to wor ...Show All
