• Visual Studio 2008 (Pre-release) .NET 3.0 overwrite LINQ?

  Hi All, Sorry if this is a stupid question but I am a bit confused over what is what with all the CTP's etc flying around. A while back I installed the May CTP of LINQ etc and I have written a prototype model layer for my app. I next wanted to create a prototype UI using WPF/XAML but the support in my VS install appears to be broken so I thought I would install the .NET 3.0 framework that has just been released and then install the latest orcas CTP. This is where I ran into problems - when I goto install the .net framework it informs me that I must unistall previous CTP copies. This is fine but I am a bit concerned that if I uninstall the prev CTP I will no longer have DLINQ support. Am I correct in this assumption Wha ...Show All

• .NET Development Web Services, Authentication,Authorization. where to go?

  Hi, im building a yahoo messenger type application using # and Web Services. I have experiance in php/mysql ect. Can people suggest what authentication/authorization system to implement. Should I add sign-up's to a sql dartabase and when they sign in, give them a random sesson string and authenticate against it. Or should i use what mirosoft have provided (what is that ) I'm new and don't know which way to go. So some direction or tutorials will be great help. Thank you. Thanks for the link. The approach i wish to use is a UsernameToken but finding a tutorial for SWE3 is hard. I find microsofts tutorials a bit hard to swallow. ...Show All

• .NET Development Dictionaries and invalid keys: return the key in the exception?

  Dictionary<TKey, TValue>.Add throws an ArgumentException if the key already exists. Dictionary<TKey, TValue>.Item throws a KeyNotFoundException if the getter is called and the key does not exist. Why do neither of these exceptions contain the key that's causing the error It seems like it would be easy to do by using Exception.Data, or at least providing the key in the KeyNotFoundException class. Another subtle reason is that exceptions should be serializable. There is no (good) way to gaurantee the key passed into Dictionary is acutally serializable therefore they can't include it in the exception. ...Show All

• Visual Studio Express Editions pasting capability in textboxes seems variable, any ideas?

  Hello all, I've written essentially two version of the same application.In the first version, the textboxes allow users to paste text into them (via Ctrl + V). However, I've noticed that in the second version, for some reason, the textboxes don't allow the user to paste information into them. I've written both using the same version of vb.net express, and all of the textboxes have the same preferences selected (to the best of my knowledge). In fact, I've coppied and pasted one of the working textboxes (one that allows pasting) into the second app, and it no logner accepts pasting. Does anyone know what might cause the applications to act in this manner How can I change this! Thanks so much for any input or ideas. -Robert I am hav ...Show All

• SQL Server Moving SQL2k to new appliance

  I am moving a SQL 2k database from a Windows 2000 server to a Windows 2003 server (seperate appliances) and would like as little SQL downtime as possible. I have several applications that I believe are connecting to servernow by servernow’s name and don’t want to have to figure out how to change them to servernew . Would it work if I built servernew and copied/moved the SQL database to servernew , then take servernow off line and change servernew’s name to servernow I am open to any suggestions on other more appropriate methods. Thanks in advance Melonheads Sister Thank you both. Looks like both documents will be very useful. Melonheads Sister ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Reformulated Discontent

  ok sorry, i calmed down a bit. hope that last post gets yanked, actually. in case they do, i'm starting a new and less emotional thread. i hope i wasn't the only one who went through some significant frustrations when just about everything went boom on that first re-compile...here's a more articulate (i hope) expression of my discontent. i understand that things need to change if it's going to be done right. however, there were many things missing that were good (i.e. WindowsGame_Starting/Exiting overridables) that are now gone. in addition, some changes were outright arbitrary. adding the full-screen feature is a good example of what you *want* to do in a second beta -- though it is a basic enough feature that i personall ...Show All

• .NET Development Web Parts/Web Zones

  I am a bit of a novice when it comes to Web Projects, but was faced with a simple project and thought WEb Parts would do the job and give me some insight into the subject. I have a Web Page with two WebZones into it... On the first Zone I have a Web Control with a listbox which will display a list of local Applications... On Zone two, there is another Web Control with a textbox.... What I want to do is quite simple(I think)...when an item in the firstzone listbox is selected, I want to display some information on the textbox on the WebZone2 WebControl.... All the examples I have found so far, deal with static information on the second Zone or wuth the ability to move controls around.... I need somebody to tell me t ...Show All

• .NET Development Can't start the exe file if compiled in Release mode

  I have a project for .net 2.0. There is a problem - I can start exe file if it was compiled in Debug mode, but can't start it if compiled in Release. There are no error messages or exceptions. The process shows for a second in Task Manager and disappears. But if I start release version from Visual Studio using F5 (start debug), it works ok. I've experimented with compile options and realised that I can't start exe file if Debug Mode is not "full" (i.e. pdbonly or none) or Optimize = true. I also tried to start exe file under WinDbg (windows native debugger). It shows that dlls are loading and then some exceptions occuring: ...

• Game Technologies: DirectX, XNA, XACT, etc. Do any big game companies use C#, VB.Net or J#

  Hi, it's me again. ;) I've posted many posts in this thread, but try to stand me. Okay. This could be a silly question, but does any big game house use C#, VB.NET or J# to program DirectX Is it possible Timo I'd also like to echo some of the sentiments in favor of .NET as a viable game platform. And I'm talking FPS, not minesweeper. I've been programming in C++ for 10 years, and after reluctantly trying C# with the release of VS2005 earlier this year, I'm finding it downright difficult to return to C++. C# is just so freaking cool. Everything is cleaner. Man, it's beautiful! My only real objection so far is the inability to code in SSE/3DNOW!, and on a lesser note, concerns over P/Invoke and GC, as well as portabil ...Show All

• Software Development for Windows Vista Easier adding of paralell branches and brackets

  Hi All, I'm a beginner in WWF, and I should implement an SQL-like(not for an SQL database, but with a similar language) query builder workflow. The query should contain only a SELECT with AND, OR, NOT and brackets. The selection is based on different characteristic, which are listed in a grid.

How can I insert the dragged activity paralell to the current selected activities or to the activity bellow it Detailled: In the samples I have seen only one way for inserting paralell activities.

• Internet Explorer Development IE7 HP Director Problem

  I can't use HP Directors or Solution Center after install IE7. I installed fresh HP software and updates. But problem persist. When reinstall IE6 back, problem solved. who knows anyway or have ideas Please help me. Thank you, Found on another forum, there is a workaround until HP issues a fix: Click (or double-click) on the Director Icon like you normally do to run it... the program is starting, but hiding. After a second or two, hit <ALT><Space> on the keyboard.  That will "pop-up" a dialog box... click "Minimize" (may have to click it twice).  You will then see the Director icon appear in the taskbar.  Click the taskbar Director button and the program will then come up and work norma ...Show All

• SQL Server NEWBIE: How do I embed and quietly install sqlserver express on a user's machine without their intervention?

  Hello, I am kind of new with .Net development and really new with using SqlExpress. Here is my question, I hope it is easy: I have a shareware program that I have been selling since 2000 and it was written in VB6 using a third party database program. What I would like to do is rewrite this application using C# and SqlServer Express. The program as it stands right now is about 5mb to download and install. My concerns: 1) How do I embed and quietly install sqlserver express to the end user's computer without them having any intervention 2) By using sqlserver express as my database how much extra overhead is going to be included in the install package I want to keep the install package as small as possible and the user experien ...Show All
