• Visual C# command prompt return immediately when running console application

  By default, a console C# app will hold the command-prompt until the app exits. Is there a setting in the .NET framework that will cause the command-prompt to return immediately This is sort of analogous to running a command in the background in unix by appending & to the command. Hi. The responsables of doing that are the shell and the OS not the C# language or the .Net framework. The OS because it must support Multitaksing (ms-dos does not) and the shell because it must do some system calls, ex fork (not exists in ms-dos) and exec, in order to provide that functionality.

• Game Technologies: DirectX, XNA, XACT, etc. download sdk

  where can i download the directX sdk I've looked all over the Microsoft site and all i can find are updates. This is really fusterating thanks. I'm new to game dev. In order to simplify things, you can always visit http://msdn.com/directx/sdk and it will point you to the most-recent SDK.  In the future, you should use the full-qualified URL like Daniel used, as it it guaranteed to be an obsolete URL within 2 months time :-) I should also add that each SDK is not an update to a previous one.  They are complete SDKs. ...Show All

• Windows Forms Permissions problem

  I have an application to log time spent on an activity. I have published it as a ClickOnce app so that it is easy for users to install, and makes sure they are aware of updates. The problem I have is that as the applications needs to run everytime wondows starts, I have a piece of code in the app startup that creates a shortcut in the users Startup group (bit of a hack I know) and on most machines this works fine. On some machines however, I get an UnauthorizedAccessException when the application runs saying that it cannot create the shortcut. To create the shortcut, I use the Windows Script Host Object Library, and call WshShell.CreateSh ...Show All

  Hi, Well, I have been trying to get this first sample "Getting Started" going for a very very long time, and so far, I've been pulling my hair out just trying to figure out what is going on. My question is, when i compile the "Getting Started sample" which is from WIndows SDK, it compiles fine, and I find client.exe but I can not find service.exe anywhere. Neither under Getting Started/service/bin folder which produces service.dll file and service.pdb nor under wwwroot/servicemodelsamples/bin directory. I got the console based sample going but I really want this IIS based samples to work as well. Any help woul ...Show All

• SQL Server does "with (nolock)" absolutely guarantee no locks are taken?

  I need to run a few short-running queries against a production system. I need to be absolutely certain that SS doesn't take out any locks on the table as a result. Does "with (nolock)" absolutely guarantee this I've read BOL on the topic and I understand isolation level read-uncommitted. But I want to validate that there's not any undocumented behavior in SS that might violate the documentation (which clearly states that no shared locks are issued). Thanks! You're talking two different things. with (nolock) is a HINT. That means there is a possibility that SS will override it. SET TRANSACTION ISOLATION LEVEL ...Show All
