• Gridview with row headers

  - by Seagull

  I am using the ASP.NET3.5 gridview control in a new project. My problem is that the gridview presents data in basic tabular format, whereas I want a grid with row header / grouping behaviors. An example of this would be Outlook web interface, which can group emails by date, as well as allowing you to select individual emails to display. My problem: I can't see how this could be easily done with Gridview? I did find a product called Telerik that has a seemingly fancy Gridview, but I am hesitant to spend money on a single components that now also locks me into a third-party framework...

• How do i handle jcupload and no flash?

  - by acidzombie24

  I am using http://www.jcupload.com/ (basic) to upload files. I am considering having a friend write a more custom version or to do magic with ajax; so the solution should be able to work without that. With jcupload i include css, a script and write <div id="jcupload_content"></div> in my html and i am done. Problem is, with no flash i get an object box. Instead i would like is an iframe or a html form to upload the file. How do i do this? Should i detect flash from javascript and overload the div myself if no flash is available? How do i detect if flash is available? with jquery i know i can write something like $('#jcupload_content').innerHtml = blah; How do i handle the flash part?

• coding an array in a class library and make a call to it C#

  - by eddy

  I'm new to C#, so this may be a basic question. What I need to do is put an array such as the one below in a class library and then make a call to it. So I'd want the aproprate picture to appear via the class and this array. I know there's a much simpler way to make certain pictures appear, but this is a requirement for the project. It's an asp.NET website in C#. string[] PictureArray; PictureArray = new string[3]; PictureArray[0] = "~/pics/grl.jpg"; PictureArray[1] = "~/pics/pop.jpg"; PictureArray[2] = "~/pics/str.jpg"; PictureArray[3] = "~/pics/unk.jpg";

• Where are config files for class libraries physically located?

  - by BadNinja

  My guess is that this question will fall under the category of "duh", but, nevertheless, I'm confused. When using config files in, for example, a Windows Forms Application, the config file can be found in C:\Program files\CompanyName\ProductName\Application.exe.config. However, with the class library I'm developing I do not see a "ClassLibrary.dll.config" file in the install folder after installing it (in tandem with another project) from Visual Studio. Even though I do not see the file anywhere, retrieving data from it works correctly. Plus, running the following code from a method within the class library returns the path you would expect: C:\Program files\CompanyName\ProductName\ClassLibrary.dll.config. If someone could shed some light on what I'm missing here, that would be really awesome. public static string MyMethod() { Assembly assem = Assembly.GetExecutingAssembly(); Configuration config = ConfigurationManager.OpenExeConfiguration(assem.Location); return "The assembly location was: " + assem.Location + Environment.NewLine + "The config file path was: " + config.FilePath; // Gives me "C:\Program files\CompanyName\ProductName\ClassLibrary.dll.config" }

• ASP.net getting NT user name returns administrator?

  - by JonH

  This doesnt seem to be an issue with windows XP. But I have an end user (my boss!!!) using windows 7 64 bit... In one of our apps we are grabbing the end user user name via: HttpContext.Current.User.Identity.Name.ToString.Substring (HttpContext.Current.User.Identity.Name.ToString.IndexOf("\") + 1).ToLower For me it is returning the correct user name for instance "jhermiz". When my boss tries getting into the app, it thinks he is Administrator??? Does anyone know of any alternative or why this might be happening? The reason this is an issue is because I use that user name to pull other information... This is visual studio 2003.

• Targetting DataTemplate for only on certain views

  - by huseyint

  I have a DataTemplate inside a global/shared ResourceDictionary like this which targets a DataType: <DataTemplate DataType="{x:Type foo:Bar}"> <!-- My DataTemplate visual tree goes here... --> </DataTemplate> This DataTemplate replaces my all foo:Bar types on all my Views (UserControls/Windows). What I want to do is to apply this template to only certain views, keeping the other views are not affected by this DataTemplate. I can copy this DataTemplate to Resources sections of each of these view, but I don't want to copy/paste the contents of the DataTemplate which would result in maintenance headaches.

• Any way to get read timeouts with Java NIO/selectors?

  - by mmebane

  I'm converting a Java server application which used blocking IO and thread-per-client to NIO and a single IO thread (probably a thread pool after I get the basic implementation done). The one thing I am having an issue with is disconnecting clients after they have been idle for a period. I had previously been using SO_TIMEOUT and blocking reads. However, with selector-based IO, reads don't block... I was hoping that I'd be able to set a timeout and be able to select on read timeout, with something like SelectionKey.isReadTimeout(), but nothing like that seems to exist. The current best solution I have come up with is to have a Timer with a TimerTask which keeps track of the keys which are waiting on read, and then canceling them and re-scheduling them on each read. Is there a better solution?

• WPF Statusbar Updates - help, I seem to be going round in circles

  - by David Ward

  I seem to be going round in circles. I have a WPF application that has a main ribbon window with a status bar. When you navigate to a "view" a user control is displayed as the content of the main window. The view has a ViewModel which handles retrieving data from the database and the View's datacontext is set to the ViewModel. What I want is to have the lengthy operation (data retrieval) run on a background thread and whilst it is running the status in the main window to report appropriately. When the background task is complete, the status should revert back to "Ready" (much the same as Visual Studio). How should I wire this together so that I can have the data access code separated out in the ViewModel whilst keeping a responsive UI? I have tried using the BackgroundWorker is various places in the code and I still end up with an unresponsive UI.

• WSDL: What do I do with it? Add service Reference? Noobie question

  - by Johnny

  Hey guys! I have been given a WSDL with all the method requests and responses, and all the objects I'll need to use for creating a few webmethods. The thing is, I don't know what to do with it. I've added the WSDL as a Service Reference. I can see the methods and structures, I can instantiate them, it's all there, but the project doesn't build as soon as I add the WSDL. "Error 2 The type name 'ServiceReference1' does not exist in the type 'WSPELab.WSPELab' C:\Users\JJ\Documents\Visual Studio 2008\Projects\WSPELab\WSPELab\Service References\ServiceReference1\Reference.cs 21 111 WSPELabSLN Is it a stupid namespace error on my part? EDIT : Forgot to add this. With the WSDL added, can I used the structures it contains directly? Or are they just "listings" for me to implement? Thanks!

• Creating an installer with WPF forms, packaged files and custom setup actions

  - by RodH257

  I'm trying to create a way of deploying a set of tools (which are add-ins to 3rd party software) to my users. I would like to do the following: User Enters Serial Dlls in their directory structure is extracted to program files a file is copied to a location in ProgramData (this registers my add-ins to the 3rd party application) Online activation for software is performed Can anyone point me into the right direction for this? I had a look at deployment projects in Visual Studio but I'm not sure if they are what I'm after. Main problem is they are ugly, I would like to have a nice WPF installer, and have a more custom experience. But I guess that can be traded off if its going to make things easier. I was thinking, I could just make my own C# project that extracts the files, but I have no idea how to package them up and extract them all as part of one download (like the MSI files that the deployment projects create). Can anyone point me in the right direction?

• Mouse interaction in ListBoxItem children (WPF)

  - by absence

  I have a ListBox with an ItemTemplate that contains a control that interacts with the mouse. This interfers with the selection functionality of the ListBox, i.e. clicking a control does not select the item. This is because ListBoxItem sets the Handled property of the mouse event to true in OnMouseLeftButtonDown. I tried the following protected override void OnMouseLeftButtonDown(MouseButtonEventArgs e) { base.OnMouseLeftButtonDown(e); e.Handled = false; } but the ListBoxItem “takes over” the mouse and prevents the control from doing its own interaction. Then I had another idea protected override void OnMouseLeftButtonDown(MouseButtonEventArgs e) { base.OnMouseLeftButtonDown(e); ((ListBoxItem)VisualTreeHelper.GetParent(VisualTreeHelper.GetParent(VisualTreeHelper.GetParent(this)))).IsSelected = true; } which actually works, but feels more like an ugly kludge than an elegant solution. Are there any better solutions that don't rely on the exact contents of the visual tree?

• sql exception when transferring project from usb to c:\

  - by jello

  I'm working on a C# windows program with Visual Studio 2008. Usually, I work from school, directly on my usb drive. But when I copy the folder on my hard drive at home, an sql exception is unhandled whenever I try to write to the database. it is unhandled at the conn.Open(); line. here's the exception unhandled Database 'L:\system\project\the_project\the_project\bin\Debug\PatientMonitoringDatabase.mdf' already exists. Choose a different database name. Cannot attach the file 'C:\Documents and Settings\Administrator\My Documents\system\project\the_project\the_project\bin\Debug\PatientMonitoringDatabase.mdf' as database 'PatientMonitoringDatabase'. it's weird, because my connection string says |DataDirectory|, so it should work on any drive... here's my connection string: string connStr = "Data Source=.\\SQLEXPRESS;AttachDbFilename=|DataDirectory|\\PatientMonitoringDatabase.mdf; " + "Initial Catalog=PatientMonitoringDatabase; " + "Integrated Security=True"; what's going on here?

• regular expression with "|"

  - by WtFudgE

  I need to be able to check for a pattern with | in them. For example an expression like d*|*t should return true for a string like "dtest|test". I'm no regular expression hero so I just tried a couple of things, like: Regex Pattern = new Regex("s*\|*d"); //unable to build because of single backslash Regex Pattern = new Regex("s*|*d"); //argument exception error Regex Pattern = new Regex(@"s*\|*d"); //returns true when I use "dtest" as input, so incorrect Regex Pattern = new Regex(@"s*|*d"); //argument exception error Regex Pattern = new Regex("s*\\|*d"); //returns true when I use "dtest" as input, so incorrect Regex Pattern = new Regex("s*" + "\\|" + "*d"); //returns true when I use "dtest" as input, so incorrect Regex Pattern = new Regex(@"s*\\|*d"); //argument exception error I'm a bit out of options, what should I then use? I mean this is a pretty basic regular expression I know, but I'm not getting it for some reason.

I know there are a lot of website downloaders out there, but I cant find something that i can use directly in my code. I have some basic scripts done in python, so Python is very welcome. but pretty much any language will do.

• Ruby Error: "No such file or directory -- script/generate (LoadError)"

  - by Jenius

  Hey all, I know that this error has been discussed elsewhere on the web, and this may seem like a stupid question, but I've got a very strange situation on my hands here. I'm running on Snow Leopard, with fully updated ruby and rails gems. I created a new rails project (ruby new testing), then navigated into that folder (cd ~/testing), and tried to create a basic scaffolding (ruby script/generate scaffold newtest name:string), and I got this error back: "ruby: No such file or directory -- script/generate (LoadError)" I have searched google thoroughly and tried to implement every solution that I could, but nothing has been working. I don't understand why I have this error or how to fix it. Can anyone help me, please?

• .NET application per-machine/per-user licensing

  - by MainMa

  I am about to implement a very basic licensing feature for my application. A serial number may be granted per-machine (or per-operating-system) or per-user (as for CAL in Windows Server: if my application is used by several users on one machine or if it is used by one user on several machines). For per-operating-system licensing, I use SerialNumber of Win32_OperatingSystem. For per-user licensing, I use: WindowsIdentity currentIdentity = WindowsIdentity.GetCurrent(); if (currentIdentity != null) { SecurityIdentifier userSid = currentIdentity.User.AccountDomainSid; Console.WriteLine(userSid); } A hash of an obtained OS serial number or SID is then stored in the database, associated with application serial; each time the program starts, it queries the server, sending hash of OS SN/SID and application serial. Is it a right thing to do it or is it completely wrong? Will it work on every Windows machine? (For example, using motherboard serial is wrong)

• How do I check if a swf file loaded correctly since put_Movie always returns S_OK?

  - by Tim

  I am using the latest flash player and have a swf file served locally from my dev machine. In one container test app I am able to play the swf and make calls to it, but in my "Real" application the same code path results in com errors (basically it looks like the swf isn;' loading properly) Additionally this is made more challenging because no matter what nonsense I put in the call to put_Movie() the return is ALWAYS S_OK. This is confusing. How am I supposed to determine if the swf file loaded and is working? As a follow-on, what would cause a swf file (the same one) not to load in a different app? The code paths are the same (from what I can tell). Obviousl something is going on, but I am not sure what. So, I guess 2 questions How to know when swf file doesn't load right Why might it fail in a different container application? I am using ATL in Visual studio 2008, latest flash, MS Vista Thanks
