• Eclispe RCP SWT menus for Windows and Mac OS

  - by Raven

  Hi, how do I configure an Eclipse RCP command style menu to match the different menu structures on Windows and on Mac OS? Mac OS X menu example http://images.apple.com/macosx/refinements/images/services_menu_20090902.jpg Windows menu example http://www.flamingpear.com/images/psp8menu.gif In the example you see, the differences in the menu structures. For example has the Mac in its application menu the preference command, the about command and the exit command. These are under Windows usally in the file menu and the about command is found in the help menu. Is there a "standard" way of doing it with RCP programs? It should somehow be possible because Eclipse itself does it. But I can not figure out how.

• C# WMI Eventwatcher code stopped working on Windows 7 with security exception

  - by Flores

  This is code that worked fine on Windows XP for years. User is not local administrator. WqlEventQuery query = new WqlEventQuery("SELECT * FROM Win32_ProcessStopTrace"); ConnectionOptions co = new ConnectionOptions(); co.EnablePrivileges = true; ManagementEventWatcher watcher = new ManagementEventWatcher(new ManagementScope(@"root\cimv2",co), query); watcher.EventArrived += StopEventArrived; watcher.Start(); This throws an SecurityException on Windows 7, Access Denied when running as a non admin. On XP this works fine without being admin. On this link MS states that 'Windows 7: Low-integrity users have read-only permissions for local WMI operations.'. I guess this is the problem. But I can't find any clue on how to change this.

• Loginview control asp.net mvc

  - by vikitor

  Hello all, I have been searching and haven't got luck, I got a tutorial to use the loginview control in order to display or hide parts of the views to different user roles in my application. The thing is that the tutorial I've found is for ASP.NET and I've been told by one of my colleages that it is the same framework for ASP.NET MVC but the way to use it is different. Have you got any good tutorial to recommend? EDIT: I've got all my application set up, and the login and the roles already configured (via asp.net membership provider). This is all already running. The thing is that if I have role a and role b I want role a to be able to actually see the links to the actions it is authorized to work with, and not b for example. If in the Index of my application I've got a link to "Edit" and only the role a can access to the action, then it will be displayed just for logged in users that belong to role a, and not to those who belong to role b Thank you, Vikitor

• Comet implementation for ASP.NET?

  - by Hitchhiker

  I've been looking at ways to implement gmail-like messaging inside a browser, and arrived at the Comet concept. However, I haven't been able to find a good .NET implementation that allows me to do this within IIS (our application is written in ASP.NET 2.0). The solutions I found (or could think of, for that matter) require leaving a running thread per user - so that it could return a response to him once he gets a message. This doesn't scale at all, of course. So my question is - do you know of an ASP.NET implementation for Comet that works in a different way? Is that even possible with IIS?

• Most used .NET namespace

  - by Michael Prewecki

  What is your most commonly used namespace in .NET. I know it will vary greatly based upon the types of projects you develop but the stack overflow audience should provide a fairly decent sample set for the types of .NET projects being developed. I'm simply interest in the name of the namespace (one namespace per answer and no one person should have more than one answer, if someone else has the same answer as you then just upvote their answer). Try to be as specific as possible (so answering System, isn't helpful). I'm after this information to help new developers focus their attention on the most common .NET namespaces...there are after all thousands of them! To start off mine is almost certainly System.Collections.Generic, I use lists of things everywhere.

• Deploying Asp.Net MVC 2 /C# 4.0 application on IIS 6

  - by Mose

  Hi, I got a problem migrating from VS.Net 2008 / MVC 1 to VS.NET 2010 (+C# 4.0) / MVC 2 The web.config has been updated, the site runs well in Cassini, but my problem now is deploying on IIS 6. I updated the web site to run using ASP.Net 4, but whatever URL I try, I always have a 404 error. It's as if the routing was not taken into account (yes, the wildcard mapping has been done). I do not understand this mess and could not google anything interesting... Thanks for your suggestions ! O.

• Git on windows :|

  - by Sonic Soul

  i've been experimenting with git as my personal code rep.. and it has been a bit of a disaster with windows. i've used Subversion, CVS, and Perforce in the past.. none were as annoying to use as git. i've figured out the PGP part (for github), although my workstation no longer lets me check in, and after searching around it turns out that git bash is using putty which is not that reliable and should be configured with something else.. i was not able to configure it with windows shell extension for a nice visual of what is part of the repository, what is modified, and easy check ins, and easy pushes.. has anyone successfully configured some kind of windows shell client and can efficiently and quickly synchronize various machines? It just seems to be more pain to use than it is worth..

• .NET : Targeting the runtime

  - by contactmatt

  I'm starting to read in-depth on the .NET framework, and its Common Language Runtime. I'm reading a .NET overview by Microsoft and I'm not sure what is meant by this statement. Code that targets the runtime is known as managed code, while code that does not target the runtime is known as unmanaged code. How do you target the Common Language Runtime? I know its defaulted when developing in Visual Studio, but how would you specifically target the CLR? What code when developing a .NET application wouldn't target the CLR, and thereby be called unmanaged code?

• Microsoft.Biztalk.explorerom.dll reference in asp.net application resulting system.nullreferenceexce

  - by sheetal.oza

  Hi, I have a asp.net application in order to start/stop applications and ports of Biztalk server 2006 r2. I have used "Microsoft.Biztalk.explorerom.dll (C:/Program Files/Biztalk Server 2006/Developer tool) " to achieve this. This is working fine on development machine since biz talk server is installed on local machine. But in the production environment (asp.net web server ,windows 2003 and iis 6.0)...this give System.nullreferenceexception (object reference not set..) at BtsCatalogExplorer explorer = (BtsCatalogExplorer)myGroup.CreateInstance(typeof(BtsCatalogExplorer)) my biztalk server and sql server are on two different box. In my setup (asp.net web application)..adding Microsoft.Biztalk.explorerom.dll and Microsoft.Biztalk.Applicationdeployment.engine.dll to GAC. But still no luck. Do i need to install biz talk server on my local machine even though I am connecting to different biz talk server?? And help is appreciated...

• Best 3D Graphics Engine for .NET

  - by George Stocker

  I've been thinking about tinkering with 3D graphics programming in .NET. In the past, I've thought about Truevision3D, and XNA, but I've not used either of these. I scanned Stackoverflow for the exact question, but neither of the (almost) relevant question (such as this question about rendering graphics, and this question about Learning Game Programming) answer my specific question. Out of the graphics engine APIs you've used for .NET, which is the easiest to use, which has the most features, and which is the cheapest? Which would you recommend for a .NET programmer to learn first?

• GetVersionEx Not Working on Windows 7?!

  - by Andreas Rejbrand

  On my Windows 7 system, the GetVersionEx Windows API function returns "6.0", indicating Windows Vista, when it should return "6.1". If it matters, I used the following Delphi code: function winver: string; var ver: TOSVersionInfo; begin ver.dwOSVersionInfoSize := SizeOf(ver); if GetVersionEx(ver) then with ver do result := IntToStr(dwMajorVersion) + '.' + IntToStr(dwMinorVersion) + '.' + IntToStr(dwBuildNumber) + ' (' + szCSDVersion + ')'; end; and the string "6.0.6002 (Service Pack 2)" was returned. Isn't this highly odd?

• Unable to send email on production server with ASP.NET MVC

  - by Davide Vosti

  I have a simple ASP.NET MVC application with a contact page. In my development machine (local) I can send successfully emails (I specify host and credentials), but on the production server this doesn't work and I get this error: System.Net.Mail.SmtpFailedRecipientException: Mailbox unavailable. The server response was: Requested action not taken: mailbox unavailable or not local at System.Net.Mail.SmtpTransport.SendMail... The server is in my LAN (the mail server too). I tried with multiple accounts but I have errors every time. Credentials for the account are provided at runtime with smtp.Credentials = new NetworkCredential("username", "password"); Any idea? Thanks

• Using transactions with ADO.NET Data Adapters.

  - by Ergwun

  Scenario: I want to let multiple (2 to 20, probably) server applications use a single database using ADO.NET. I want individual applications to be able to take ownership of sets of records in the database, hold them in memory (for speed) in DataSets, respond to client requests on the data, perform updates, and prevent other applications from updating those records until ownership has been relinquished. I'm new to ADO.NET, but it seems like this should be possible using transactions with Data Adapters (ADO.NET disconnected layer). Question part 1: Is that the right way to try and do this? Question part 2: If that is the right way, can anyone point me at any tutorials or examples of this kind of approach (in C#)? Question part 3: If I want to be able to take ownership of individual records and release them independently, am I going to need a separate transaction for each record, and by extension a separate DataAdapter and DataSet to hold each record, or is there a better way to do that? Each application will likely hold ownership of thousands of records simultaneously.

• Validating only selected fields using ASP.NET MVC 2 and Data Annotations

  - by thinknow

  I'm using Data Annotations with ASP.NET MVC 2 as demonstrated in this post: http://weblogs.asp.net/scottgu/archive/2010/01/15/asp-net-mvc-2-model-validation.aspx Everything works fine when creating / updating an entity where all required property values are specified in the form and valid. However, what if I only want to update some of the fields? For example, let's say I have an Account entity with 20 fields, but I only want to update Username and Password? ModelState.IsValid validates against all the properties, regardless of whether they are referenced in the submitted form. How can I get it to validate only the fields that are referenced in the form?

• Change Visual Studio Default Browser in an ASP.NET MVC project

  - by Kirschstein

  FireFox is set to my Windows default browser. I want to change the default browser used by Visual Studio for debugging. Normally the route I'd take to do this is right clicking on an .aspx file and setting the default from the Browse With... dialog. Unfortunately, ASP.NET MVC Views don't have the Browse With... option. What other ways can you set the default browser for ASP.NET MVC projects? Related, but NOT ASP.NET MVC Specific: Visual Studio opens default browser instead of IE

• Using Base SAS to validate Windows Password

  - by Bazil

  We have a signon script that requires a Windows password in order to access and validate against the SAS metadata server. The problem is that if the windows password is changed, and the script is run a few without being updated, then the user gets locked out and has to call IT support for a password reset. What is the simplest way of using Base SAS to validate a windows password? ie to enable a warning to the user if the password provided is not valid... EDIT: The concern is not whether or not this SHOULD be done, only HOW it could be done!

• seeing C# windows forms project code from F#

  - by Pessimist

  I have a C# Windows Forms project open with some C# code in it. Question: How can I have an F# file that I can write F# code in but still referencing all the C# code I have on Form1.cs (including the GUI). I can successfully do this: - Create a C# Windows Forms project - Create a F# Library project - Reference the F# Library DLL from my C# project - That way I can call F# functions from C# But I still can't see my buttons and textboxes from F# I understand that that is because it's a library and it can't reference System.Windows.Forms So how do I fix this? I don't want it to be a library or this or that, I just want it to be a file that will allow me to write F# code while being able to reference my C# Form and code. I guess you can say I want an F# file that is also a "partial class Form1" so that I can continue writing code for the same Project, but using F# instead. How do I do that?

• Using C# and VB.NET in one solution

  - by Younes

  I'm busy on a small project to convert an Access2003 db to .NET. I am trying to integrate my functionality in an excisting project that is being used for Administration of some kind. The code in this project is vb.net. I started by setting up my Data Access Layer, which seems to work fine. I can make new web pages that acces the data I need. However when i start to use class files to set up my Business Logic Layer i can't build my project when using C# instead of VB. I Dislike VB and like to program in C# as i know the syntax alot better etc. Is it possible to program using C# knowing that VB.NET was the language chosen to buold the entire project on? If not, what will be the smartest way to integrate my module into the project using my favorite programming language? (Make a project and reference to the dll?)

• How do I choose files from the local filesystem in Windows Phone 7

  - by Kris Erickson

  I'm trying to choose some files to upload in Windows Phone 7 (in the emulator), and any attempt to ShowDialog of the OpenFileDialog leads to a Security Exception. The open file dialog is being called from an event on a button click but I get a SecurityException [FileDialog_ActiveScripting] Arguments: Debugging resource strings are unavailable. Often the key and arguments provide sufficient information to diagnose the problem. See http://go.microsoft.com/fwlink/?linkid=106663&Version=3.0.40806.0&File=System.Windows.dll&Key=FileDialog_ActiveScripting Looking up the SecurityException in the Silverlight version of OpenFileDialog.ShowDialog states that the error is: Active Scripting in Internet Explorer is disabled. -or- The call to the ShowDialog method was not made from user-initiated code. Anyone had any luck with the OpenFileDialog and ShowDialog in Windows Phone 7?

• Access to variables in an asp.net user control vs an include file

  - by user204588

  I've asked this question before but couldn't get the answer I was looking for so I'm going to try it again. I'm translating pages from old asp to asp.net and I don't want to do this any other way so I really just want to know if this can be done. In asp, I'd assign a variable on one page <% myVar = "something" %> I could assign many variables here and then use an include <!--#include file="Test2.aspx"--> then in test2 file, I could access all the variables without having to pass all the variables into the control or declaring them again, like <% myVar = "something else" %> I want to do this the dot net way but I have some thirty variables on the page and i don't want to pass a bunch into the user control and I don't want to have to keep declaring the same variables. All I really want to know is if there is some way to replicate the behavior above in asp.net?

• AES Encryption. From Python (pyCrypto) to .NET

  - by Why

  I am currently trying to port a legacy Python app over to .NET which contains AES encrpytion using from what I can tell pyCrpyto. I have very limited Python and Crypto experience. The code uses the snippet from the following page. http://www.djangosnippets.org/snippets/1095/ So far I believe I have managed to work out that it that it calls Crypto.Cipher with AES and the first 32 character of our secret key as the password, but no mode or IV. It also puts a prefix on the encrpyed text when it is added to database. What I can't work out is how I can decrypt the existing ecrypted database records in .NET. I have been looking at RijndaelManaged but it requires an IV and can't see any reference to one in python. Can anyone point me in the dirrection to what method could be used in .NET to get the desired result.

• JSP/JSF conversion to ASP.NET

  - by sharru

  I have a pretty big JSF web application. I must convert the application to ASP.NET. I already converted the Java code to C# code manually and also using JCLA (Java Language Conversion Assistant from Microsoft). What is the best way to convert the JSF part to ASP.NET? Is there any tool that can help shorten the work? For example convert JSF <t:dataList> to ASP.NET datagrid, or converting panelGroup to asp:panel, etc...

• Sharing ASP.NET State databases between multiple apps

  - by MikeWyatt

  Is it better for a collection of ASP.NET web apps to share the same session database, or should each one have its own? If there is no significant difference, having a single database would be preferable due to easier maintenance. Background My team has an assortment of ASP.NET web apps, all written in either Monorail 1.1 or ASP.NET MVC 1.0. Each app currently uses a dedicated session state database. I'm working on adding a new site to that list, and am debating whether I should create another new session database, or just share an existing one with another app.

• Compiling my own PHP extension on Windows with Visual Studio 2008

  - by Mickey Shine

  I wrote a PHP extension and it could be compiled and run under linux successfully. But on windows, I met some problems. I did the compiling on windows according to http://blog.slickedit.com/?p=128 with PHP source version 5.2.10, and after the compiling it generated the dll file. But when I tried to use the dll file, it reported me the memory problems when starting Apache(Wamp server). And then I started the debugging process, it seemed that REGISTER_INI_ENTRIES() had problems. Here is the PHP extension source code, http://www.bluefly.cn/xsplit.tar.gz , and it works fine on Linux. But I also want to make it work on Windows. Sorry I am not a pro so that I hope someone can help me. Any help is appreciated and thanks in advance~

• Parsing plain Win32 PE File (Exe/DLL) in .NET

  - by Usman

  I need to parse plain Win32 DLL/Exe and need to get all imports and exports from it and to show it on console or GUI(say Win Forms). Is it possible to parse Win32 DLL/Exe in C#.NET, read its export table,import table and get managed types from it. As its unmanaged PE(.NET doesn't allows you to convert unmanaged PE files to managed .NET assemblies, only it generates COM managed assemblies). So how to parse export and import tables of PE files and take all methods(signatures from it) in managed form.(e.g if char* as argument, it should display as IntPtr)
