• VB.NET localization

  - by PandaNL

  In my winform app in VB.NET I want to use the localization option. But i have a few questions/problems. I'm using a menu strip to select an other language. But it seems that is doesn't change my menustip text to my selected language. It does change my labels, buttons, and textboxes but menu strips don't seem to change when I choose another language. Also is it possible to get those resx files such as MyForm.fr-FR.resx compiled so it isn't an external file outside my app? Or to get those files in an Language folder at the same location of my app, so i don't have all those fr-FR, nl-Nl folders in the same location as my program?

• Visual Studio does not flag unterminated string constant in VB.Net

  - by JoelFan

  I noticed that if I leave off the terminating double quote for a string constant in Visual Studio 2010, there is no error or even a warning, i.e. Dim foo as String = "hi However, the continuous integration tool we are using flags an error: error BC30648: String constants must end with a double quote. What's going on here? Is there some language rule in VB.NET that makes a terminating double quote optional "sometimes"? Is there some setting in Visual Studio that will make it flag this as an error?

• What is the worst C#/.NET gotcha?

  - by MusiGenesis

  This question is similar to this one, but focused on C# and .NET. I was recently working with a DateTime object, and wrote something like this: DateTime dt = DateTime.Now; dt.AddDays(1); return dt; // still today's date! WTF? The intellisense documentation for AddDays says it adds a day to the date, which it doesn't - it actually returns a date with a day added to it, so you have to write it like: DateTime dt = DateTime.Now; dt = dt.AddDays(1); return dt; // tomorrow's date This one has bitten me a number of times before, so I thought it would be useful to catalog the worst C# gotchas.

• Async trigger for an update panel refreshes entire page when triggering too much in too short of tim

  - by Matt

  I have a search button tied to an update panel as a trigger like so: <asp:Panel ID="CRM_Search" runat="server"> <p>Search:&nbsp;<asp:TextBox ID="CRM_Search_Box" CssClass="CRM_Search_Box" runat="server"></asp:TextBox> <asp:Button ID="CRM_Search_Button" CssClass="CRM_Search_Button" runat="server" Text="Search" OnClick="SearchLeads" /></p> </asp:Panel> <asp:UpdatePanel ID="UpdatePanel1" runat="server"> <Triggers> <asp:AsyncPostBackTrigger ControlID="CRM_Search_Button" /> </Triggers> <ContentTemplate> /* Content Here */ </ContentTemplate> </asp:UpdatePanel> In my javascript I use jQuery to grab the search box and tie it's keyup to make the search button click: $($(".CRM_Search_Box")[0]).keyup( function () { $($(".CRM_Search_Button")[0]).click(); } ); This works perfectly, except when I start typing too fast. As soon as I type too fast (my guess is if it's any faster than the data actually returns) the entire page refreshes (doing a postback?) instead of just the update panel. I've also found that instead of typing, if I just click the button really fast it starts doing the same thing. Is there any way to prevent it from doing this? Possibly prevent 2nd requests until the first has been completed? If I'm not on the right track then anyone have any other ideas? Thanks, Matt

• Problem with Regex in .NET (C#)

  - by Craig Bovis

  I'm trying to write a a regex to validate a string to match the following rules. Must start with a-z (case insensitive) Must only contain a-z A-Z 0-9 . - I've put something together based on my limited knowledge and ran it through an online testing tool for a whole bunch of situations and the results were as I had hoped however when I place the pattern into my .NET code it doesn't match correctly. The pattern I am using is, [a-zA-Z][a-zA-Z0-9.\-]* Is this the correct pattern or am I barking up the wrong tree? Some examples of what I'm expecting. craig.bovis - VALID 24craig - INVALID craig@bovis - INVALID craig24 - VALID -craig24 - INVALID craig24.bovis-test - VALID

• Relationship between .NET ClassLoader and Assembly

  - by smwikipedia

  I am wondering about the relationship between .NET ClassLoader and Assembly I use the "!dumpdomain xxxx" command and got the following output: Domain 1: 00522108 LowFrequencyHeap: 0052212c HighFrequencyHeap: 00522178 StubHeap: 005221c4 Stage: OPEN SecurityDescriptor: 00523430 Name: BoxUnbox.exe **Assembly**: 0056eb88 [C:\Windows\assembly\GAC_32\mscorlib\2.0.0.0__b77a5c561934e089\mscorlib.dll] **ClassLoader**: 0056ec08 SecurityDescriptor: 0056c078 Module Name 56d71000 C:\Windows\assembly\GAC_32\mscorlib\2.0.0.0__b77a5c561934e089\mscorlib.dll **Assembly**: 005794f0 [] **ClassLoader**: 00579570 SecurityDescriptor: 0057a018 Module Name 00152c5c I noticed that the "ClassLoader" and "Assembly" appear in pair. It seems each Assembly is accompanied with its own "ClassLoader". Why like this? Is this a litte noisy? Why not just assign one "ClassLoader" to a AppDomain and use it to load all the used Assembly into the AppDomain? Isnt't this design more elegant? Many thanks.

• .NET Active Directory Password Expiration on Windows 2008

  - by Brent Pabst

  Searched SO and Everywhere else, including the .net developers guide to directory services programming book - no luck. I am trying to create a simple password reset web page that allows the user to change their password. The change password portion of the code is working fine. For the users I would also like to display when their current password will expire next. Using the sample code from the book mentioned above I was able to get all of the code setup however, the attribute that is returned is always equal to Long.MinValue and hence cannot be inverted to a positive number, plus this means it did not find the proper domain setting. Does anyone have sample code or references for getting the password expiration in a Windows 2008 or R2 domain environment where password policies can be different for each user?

• Exposing.NET assembly as COM 101

  - by Jan Zich

  I have trouble to expose a .NET assembly in COM. It seems that I must be missing some basic step because I think I followed all tutorials and documentation I found as well as common sense, but still when I do (in a test VBScript): Set o = CreateObject("MyLib.MyClass") It keeps saying that the object cannot be created. Here are the steps I have done: I have simple one method dummy class with no attributes. The class is in a class library which has "Make assembly COM-visible" ticked in Visual Studio. The class library is signed. The DLL is registered via RegAsm.exe with the /codebase parameter (I don’t want / cannot add the DLL to GAC). Just to be sure, I tried to copy the library to the same directory as the test VBScript, but it does not help. Edit: I should have mentioned that the I can instantiate the class in COM if I put the DLL into GAC.

• .NET command line argument bug?

  - by Tomas

  Hello, I am trying to read command lien argument but it seems there is some kind of bug in .NET. The parameter which I pass to my console application /i "C:\Projects\PC\trunk\Simulator\PDF-Source\PDF-Source\bin\Debug\ConversionFiles\dummy.pdf" /o "result" CommandLine variable return three arguments, but I pass four and values of these arguments messed up. /i = true "C:\Projects\PC\trunk\Simulator\PDF-Source\PDF-Source\bin\Debug\ConversionFiles\dummy.pdf" = true /o = "result" As you see only the last argument is parsed corectlly. Is this bug? regards, Tomas My code static void Main(string[] args) { Arguments CommandLine = new Arguments(args);

• Bad http connection (400) from Simple Native Iphone App to test .net Web Service

  - by leo

  Dear all, I have written a simple hello world .net web service which will accept 2 parameters and return the parameters as a string. The web service is hosted by IIS on a windows xp pc. I am able to access the web service using safari on the iphone simulator, successfully tested the operation using HTTP POST by clicking the "invoke" button. However, when I use the native app on the iphone simulator, I keep getting a bad http connection error 400 on the IIS log. I have tested my native app with http://viium.com/WebService/HelloWorld.asmx and it works. I have already added Does anyone know what is wrong? Is it some settings that have not configured correctly? Thank you very much in advance.

• Wanted a tool for decompiling obfuscated .NET code

  - by Shrike

  Hello. I need a tool to decompile obfuscated .NET code. Yes, I know about Reflector and its plugins (FileDisassemble, FileGenerator). But they create VS project which won't compile. For an example the decompiled code contains: private sealed class d__0 : IEnumerator, IEnumerator, IDisposable { private int <1__state; private int <2__current; I need a tool which could rename automatically such name into readable (read "compilable") form. Thnx.

• Tutorials for .NET database app

  - by ChrisC

  My earlier question and comments are at "What is ADO.NET". This shows my level of knowledge about c# database apps. Can someone point me to tutorials and/or primers that can help me proceed from where I am (also stated in other question)? I've looked and all I've found are tutorials that talk about general db basics (ie, not helping with VS/C#), or talk about connecting to existing SQL db's. I need help setting one up and configuring it, as well as help on how to create and use queries to test the db schema.

• Good tools which generate NUnit unit tests for .NET assemblies in Visual Studio 2008

  - by andy

  Hey guys, I'm pretty new to Unit Testing so bare with me. I realize that best best practice is not to auto generate unit tests, however I'd like to use Code Generation to set-up the basic skeleton of the tests. Now, I know Visual Studio 2008 already has the built in "create tests", however, it just creates a flat list of all the classes it's going to test... and it's not for NUnit right? Ideally, I'd like the code generation to follow the folder AND namespace structure of the assembly its generating tests for. Can you guys recommend any good tools which generate NUnit unit tests for .NET assemblies in Visual Studio 2008? cheers!

• ORM For .Net ON Oracle

  - by moi_meme

  I'm gonna start a new project soon, using .Net 3.5 and Winform on an Oracle database. We were planning on using an ORM, NHibernate was suggested by our architect. Since I'm personnaly more familiar with Entity Framework, i thought it would be easier to use than NHibernate. But since there aren't any official provider from Oracle, we are resistant on using it. So my Question, I Looked at different provider available and found some: DevArt DataDirct EFOracleProvider So I'd like to have some feed back on each of them, pros and con, missing feature, stuff like that, from those using them, and know if we're better of with NHibernate? Thanks for the help.

• stringtemplate .net dynamic object

  - by Mark Milford

  Hi I am using string template to render some content, but the content may be variable so not sure how to pass it in (using .net / c#) Basic idea is I have a List which need to end up as parameters, e.g. List<KeyValuePair<string, object>> ret = new List<KeyValuePair<string, object>>(); ret.Add(new KeyValuePair<string, object>("elem1", true)); ret.Add(new KeyValuePair(string, object>("elem2", false)); Now I want these to show up in string template as: $item.elem1$ $item.elem2$ I can get them to be $elem1$ or $elem2$ but i need them inside of a structure. So I in effect need to convince the string template setAttribute that I'm passing in an object with properties elem1 and elem2 when in fact I have a List of KeyValuePairs. Thanks

• Simple .NET webcam library

  - by Vegard Larsen

  Is there a simple library for .NET that has a simply API that let's you do something like; // pseudo-code List<Webcam> cams = Webcam.GetAll(); Image i = cams[0].GrabImage(); I've looked at DirectShow and WIA, both seem to be much more complicated than this. I've also looked at this CodeProject project, but it really is much more complicated than what I need. The library should support image grabbing and video grabbing, and preferably live streaming of video. Edit: It is preferable if it is free (or at least very cheap), as this is a hobby project.

• Can you recommend a .net template engine?

  - by serg10

  I am looking for a .net templating engine - something simple, lightweight, stable with not too many dependencies. All I need it for at the moment is creating templated plain text and html emails. Can anyone give me a good recommendation? If it helps at all - something like Java's Freemarker or Velocity libraries. [UPDATE] Thanks for the answers so far - much appreciated. I am really intested in recommendations or war stories from when you have used these libraries. Seems to be the best way to make a decision without trying each in turn.

• .NET SortedDictionary But Sorted By Values

  - by Michael Covelli

  I need a data structure that acts like a SortedDictionary<int, double> but is sorted based on the values rather than the keys. I need it to take about 1-2 microseconds to add and remove items when we have about 3000 items in the dictionary. My first thought was simply to switch the keys and values in my code. This very nearly works. I can add and remove elements in about 1.2 microseconds in my testing by doing this. But the keys have to be unique in a SortedDictionary so that means that values in my inverse dictionary would have to be unique. And there are some cases where they may not be. Any ideas of something in the .NET libraries already that would work for me?

• Asp.Net application/web service not working on Vista/IIS7: access right problem?

  - by Achim

  I have an .Net 3.5 based web service running at http://localhost/serivce.svc/. Then I have a Asp.Net application running at http://localhost/myApp. In Application_Load my App reads some XML configuration from the web service. That works fine on my machine, but: On Vista with IIS7 the request to the web services fails. The web service can be accessed via the browser without any problem. I configured the app pool of my App to run as admin. I added the admin to the IIS_USRS group, but it still cannot access the web service. impersonate=true/false seems not to make a difference.

• PHP + SQL Server or VB.NET + MySQL

  - by Muhammad Mussnoon

  Can someone suggest that out of the two mentioned (odd?) combinations, which is less odd, or in other words, is less trouble to work with + maintain. If it helps, the system is going to have two front-ends - one web application and one desktop application. The desktop application is going to be coded using VB.NET, and the web application in PHP. There's really no reason why the desktop application can't be replaced by a web application as well - except that one of the programmers seem to really want to code it in VB.... However, none of us have experience working with either of these pairs (you could easily call us n00bs), so we are a bit apprehensive to start. P.S. hosting service will be gotten from some provider and not be on the client's own server.

• Mimicking basic fcntl or SetHandleInformation call in .Net

  - by Tristan

  Tornado enables win32 support by faking Python's fcntl function using SetHandleInformation, which is available via ctypes on Windows. After some other small fixes, this actually works using IronPython on Windows as well (sadly, IronPython is five times slower). I'd like to get Tornado working on any CLI platform, such using Mono on OSX or Linux. Is there a managed, cross-platform, .Net approach that can fake fcntl? Here's the win32 code from Tornado: SetHandleInformation = ctypes.windll.kernel32.SetHandleInformation SetHandleInformation.argtypes = (ctypes.wintypes.HANDLE, ctypes.wintypes.DWORD, ctypes.wintypes.DWORD) SetHandleInformation.restype = ctypes.wintypes.BOOL HANDLE_FLAG_INHERIT = 0x00000001 F_GETFD = 1 F_SETFD = 2 F_GETFL = 3 F_SETFL = 4 FD_CLOEXEC = 1 os.O_NONBLOCK = 2048 FIONBIO = 126 def fcntl(fd, op, arg=0): if op == F_GETFD or op == F_GETFL: return 0 elif op == F_SETFD: # Check that the flag is CLOEXEC and translate if arg == FD_CLOEXEC: fd = int(fd) success = SetHandleInformation(fd, HANDLE_FLAG_INHERIT, arg) if not success: raise ctypes.GetLastError() else: raise ValueError("Unsupported arg") else: raise ValueError("Unsupported op")

• Disabling scoring in Lucene(.NET)

  - by user72185

  Hi, When searching, is there a way to disable scoring for any query? The scenario is that the user refines his query by trying different combinations of words, phrases etc., and needs realtime (well, reasonably fast at least) responses on the number of hits. Search time slows down a lot when there are millions of hits due to scoring, but the user really doesn't care about all these documents. As soon as he sees there are 1M+ hits he will start adding additional words to the query. A "Sort by relevance" option would allow him to do this quickly, while turning scoring back on when the number of hits is reasonable. Is this possible? I'm using Lucene.NET 2.9.2 but AFAIK it is identical to the Java version.
