• What exactly is the "Multi-threaded Debug DLL" Runtime Library option doing in VS 2008?

  - by GregH

  I have a solution in VS 2008 that creates a DLL. I then use that DLL in another application. If I go in to the DLL projects property pages and change the following configuration for a DEBUG build then the built dll no long provides the desired functionality. If I change it back and rebuild the DLL, then the DLL does provide the correct functionality: Property Pages = Configuration Properties = C/C++ = Code Generation = Runtime Library If set to "Multi-threaded Debug DLL (/MDd)" then everything works as it should. I get the correct functionality from the DLL If set to "Multi-threaded DLL (/MD)" then the DLL does not function properly...no runtime errors or anything, it just doesn't work (The DLL is supposed to plot some lines on a map but does not in this mode). So the question is, why does using the /MDd flag result in correction functionality of the underlying code, while /MD results in incorrect functionality? A little background...somebody else developed the DLL in C++ and I am using this DLL in a VB.net application.

• How can I stop SQL Server Reporting Services 2008 going to sleep?

  - by Nick

  I have SSRS 2008 set-up on a server. All works fine except that if left inactive for a length of time the next time a request is made to the server it takes a long time for it to service it. I think this is to do with the worker process being shutdown after being idle for a certain length of time. However, as SSRS 2008 isn't managed through IIS I can't find any settings that I can adjust to stop this from happening. In IIS I'd go to the Performance tab of the Application Pool Properties and choose not to shutdown the worker process. How can I do this for SSRS 2008?

• Binding to a WPF hosted control's DependencyProperty in WinForms

  - by Reddog

  I have a WinForms app with some elements that are hosted WPF user controls (using ElementHost). I want to be able to bind my WinForm's control property (Button.Enabled) to a custom DependencyProperty of the hosted WPF user control (SearchResults.IsAccountSelected). Is it possible to bind a System.Windows.Forms.Binding to a property managed by a DependencyProperty? Also, since I know the System.Windows.Forms.Binding watches for INotifyPropertyChanged.PropertyChanged events - will a property backed by a DependencyProperty automatically fire these events or will I have to implement and manage the sending of PropertyChanged events manually?

• robocode engine: how to design (write) the runtime engine -- the robot world

  - by Bob

  IBM has (had) a free learn-Java program called RoboCode, in which custom robots could be written that would then do battle in a 2D space. I would like to write the environment that supports such robots, but don't know what pattern or design to use. Each robot is a thread. Each thread is given a certain (indeterminate) amount of run-time by the JRE. A robot world engine would start by building a list of the players/robots, then enter a loop that allows each player in turn to do whatever it likes: move forward, turn left, fire toward the northwest corner, whatever. Each robot is also informed of events of interest: an enemy or several enemies are within range, it has been hit by a bullet, etc. The combination of handling threads that are also event listeners (are they also producers?) confuses me; it seems that there's more to the game engine. Even some general ideas would help. TIA.

• wpf binding by selected value - swap out bound object without disturbing binding

  - by Andy Clarke

  Hi, I've got combo box bound to a custom collection type - its basically an overridden ObservableCollection which I've added a facility to update the underlying collection (via Unity). I don't want to confuse the issue too much, but thats the background. My xaml looks like this <ComboBox ItemsSource="{Binding Manufacturers}" DisplayMemberPath="Name" SelectedValuePath="ID" SelectedValue="{Binding Vehicle.ManufacturerID}" /> And in my overridden collection i was doing this. index = IndexOf(oldItem); Insert(index, (T)newItem); RemoveAt(index + 1); I had hoped because it was bound by value, that inserting the new object(which had the same id) and then removing the old one would work. But it seems that although its bound by SelectedValue it still knows that its being swapped for a different one. The combo just looses its selection. Can anyone help please?

• Email attachment parsing via mime4j

  - by Ashish

  Hi, I am using a small java smtp library (http://code.google.com/p/subethasmtp/), by this I need to parse the incoming emails in separate components viz body, attachments etc. I am trying to use mime4j , but the documentation suggests that mime4j can only give event notification or token notification and nothing else. For stripping out body and attachments etc I had to use my own custom logic inside the event handlers. Is my observation correct? If yes then how can I use mime4j to use for my requirement. Please suggest. I badly need an approach that takes in the smtp data stream and returns me with an array of attachment references or streams in fully parsed out form in java. Please help. Thanks in advance Ashish Sharma

• CLang error (objective C): value stored during initialization is never read

  - by Scott Pendleton

  Foo *oFoo = [[[Foo alloc] init] autorelease]; This is how I was taught to program in Objective C, yet the CLang error checker complains that the initial value was never read. But oFoo is an object with properties. oFoo itself has no single value. The property values are what matter. oFoo.PropertyA = 1; oFoo.PropertyB = @"Hello, World." Should I just ignore this? Is this worth fixing? What is the fix, seeing that "initial value" is meaningless in my context?

• Returning objects with autorelease but I still leak memory

  - by gok

  I am leaking memory on this: my custom class: + (id)vectorWithX:(float)dimx Y:(float)dimy{ return [[[Vector alloc] initVectorWithX:dimx Y:dimy] autorelease]; } - (Vector*)add:(Vector*)q { return [[[Vector vectorWithX:x+q.x Y:y+q.y] retain] autorelease]; } in app delegate I initiate it: Vector *v1 = [[Vector alloc] initVector]; Vector *v2 = [[Vector alloc] initVector]; Vector *vtotal = [[v1 add:v2] retain]; [v1 release]; [v2 release]; [vtotal release]; How this leaks? I release or autorelease them properly. The app crashes immediately if I don't retain these, because of an early release I guess. It also crashes if I add another release.

• Silverlight Chat WrapPanel Crash / Bug

  - by Matt

  I've been given the task to create a simple Silverlight chat box for two people. My control must adhere to the following requirements Scrollable Text must wrap if it's too long When a new item / message is added it must scroll that item into view Now I've successfully made a usercontrol to meet these requirements, but I've run into a possible bug / crash that I can't for the life of me fix. I'm looking for either a fix to the bug, or a different approach to creating a scrollable chat control. Here's the code I've been using. We'll start with my XAML for the chat window <ListBox x:Name="lbChatHistory" Grid.Row="0" Grid.Column="0" Grid.ColumnSpan="2" ScrollViewer.VerticalScrollBarVisibility="Visible" ScrollViewer.HorizontalScrollBarVisibility="Disabled" > <ListBox.ItemTemplate> <DataTemplate> <Grid Background="Beige"> <Grid.ColumnDefinitions> <ColumnDefinition Width="70"></ColumnDefinition> <ColumnDefinition Width="Auto"></ColumnDefinition> </Grid.ColumnDefinitions> <TextBlock x:Name="lblPlayer" Foreground="{Binding ForeColor}" Text="{Binding Player}" Grid.Column="0"></TextBlock> <ContentPresenter Grid.Column="1" Width="200" Content="{Binding Message}" /> </Grid> </DataTemplate> </ListBox.ItemTemplate> </ListBox> The idea is to add a new Item to the listbox. The Item (as layed out in the XAML) is a simple 2 column grid. One column for the username, and one column for the message. Now the "items" that I add to the ListBox is a custom class. It has three properties (Player, ForeColor, and Message) that I using binding on within my XAML Player is a string of the current user to display. ForeColor is just a foreground color preference. It helps distinguish the difference between messages. Message is a WrapPanel. I programmatically break the supplied string on the white space for each word. Then for each word, I add a new TextBlock element to the WrapPanel Here is the custom class. public class ChatMessage :DependencyObject, INotifyPropertyChanged { public event PropertyChangedEventHandler PropertyChanged; public static DependencyProperty PlayerProperty = DependencyProperty.Register( "Player", typeof( string ), typeof( ChatMessage ), new PropertyMetadata( new PropertyChangedCallback( OnPlayerPropertyChanged ) ) ); public static DependencyProperty MessageProperty = DependencyProperty.Register( "Message", typeof( WrapPanel ), typeof( ChatMessage ), new PropertyMetadata( new PropertyChangedCallback( OnMessagePropertyChanged ) ) ); public static DependencyProperty ForeColorProperty = DependencyProperty.Register( "ForeColor", typeof( SolidColorBrush ), typeof( ChatMessage ), new PropertyMetadata( new PropertyChangedCallback( OnForeColorPropertyChanged ) ) ); private static void OnForeColorPropertyChanged( DependencyObject d, DependencyPropertyChangedEventArgs e ) { ChatMessage c = d as ChatMessage; c.ForeColor = ( SolidColorBrush ) e.NewValue; } public ChatMessage() { Message = new WrapPanel(); ForeColor = new SolidColorBrush( Colors.White ); } private static void OnMessagePropertyChanged( DependencyObject d, DependencyPropertyChangedEventArgs e ) { ChatMessage c = d as ChatMessage; c.Message = ( WrapPanel ) e.NewValue; } private static void OnPlayerPropertyChanged( DependencyObject d, DependencyPropertyChangedEventArgs e ) { ChatMessage c = d as ChatMessage; c.Player = e.NewValue.ToString(); } public SolidColorBrush ForeColor { get { return ( SolidColorBrush ) GetValue( ForeColorProperty ); } set { SetValue( ForeColorProperty, value ); if(PropertyChanged != null) PropertyChanged(this, new PropertyChangedEventArgs( "ForeColor" )); } } public string Player { get { return ( string ) GetValue( PlayerProperty ); } set { SetValue( PlayerProperty, value ); if ( PropertyChanged != null ) PropertyChanged( this, new PropertyChangedEventArgs( "Player" ) ); } } public WrapPanel Message { get { return ( WrapPanel ) GetValue( MessageProperty ); } set { SetValue( MessageProperty, value ); if ( PropertyChanged != null ) PropertyChanged( this, new PropertyChangedEventArgs( "Message" ) ); } } } Lastly I add my items to the ListBox. Here's the simple method. It takes the above ChatMessage class as a parameter public void AddChatItem( ChatMessage msg ) { lbChatHistory.Items.Add( msg ); lbChatHistory.ScrollIntoView( msg ); } Now I've tested this and it all works. The problem I'm getting is when I use the scroll bar. You can scroll down using the side scroll bar or arrow keys, but when you scroll up Silverlight crashes. FireBug returns a ManagedRuntimeError #4004 with a XamlParseException. I'm soo close to having this control work, I can taste it! Any thoughts on what I should do or change? Is there a better approach than the one I've taken? Thanks in advance. UPDATE I've found an alternative solution using a ScrollViewer and an ItemsControl instead of a ListBox control. For the most part it's stable.

• How to read a Choice Field from Sharepoint 2010 Client Object Model

  - by Eric

  Hello, I'm using Sharepoint 2010 Object Model. I'm trying to retrive the content of a Custom List. Everything works fine except if when I try to retrieve a Choice Field. When I try to retrieve the choice field, I got an PropertyOrFieldNotInitializedException exception... Here is the code I'm using: ClientContext clientContext = new ClientContext("https://mysite"); clientContext.FormsAuthenticationLoginInfo = new FormsAuthenticationLoginInfo("aaa", bbb"); clientContext.AuthenticationMode = ClientAuthenticationMode.FormsAuthentication; List list = clientContext.Web.Lists.GetByTitle("mylist"); CamlQuery camlQuery = new CamlQuery(); camlQuery.ViewXml = "<View/>"; ListItemCollection listItems = list.GetItems(camlQuery); clientContext.Load(listItems); clientContext.ExecuteQuery(); foreach (ListItem listItem in listItems) { listBoxControl1.Items.Add(listItem["Assigned_x0020_Company"]); } Thank you for you help!

• Entity Framework and consuming a WCF service

  - by nakori

  I'm getting data where the database is hidden behind a WCF service. Is it possible to use Entity Framework in a scenario where I have custom objects coming from a web service? (No access to the external database, and no current plans for insert/update/delete logic) Starting with an empty EF model and adding an entity I get this error on compile: No mapping specified for instances of the EntitySet and AssociationSet in the EntityContainer .. Is it possible to make an entity this way, and fill it with data received from an object? (In this case a WCF, but could also be a predefined model class/xml data) If the web service retured a Customer object I could do something like this with a dataset: Make an unbound table and do a loop through the customer properties adding them to a temp row, add it with tbl_Customer.Addtbl_CustomerRow(customerRow) to get my view filled. thanks, nakori

• Google Charts Through CURL

  - by swt83

  I have a PHP class that helps me generate URLs for custom charts using Google Chart service. These URLs work fine when I load them in my browser, but I'm trying to pull them using CURL so I can access the charts on secure https websites. Whenever I try and pull a chart via CURL, I get an Error 400 Bad Request. Any idea on how to get around this? Everything I have tried has failed. $url = urldecode($_GET['url']); $session = curl_init($url); // Open the Curl session curl_setopt($session, CURLOPT_HEADER, false); // Don't return HTTP headers curl_setopt($session, CURLOPT_RETURNTRANSFER, true); // Do return the contents of the call $image = curl_exec($session); // Make the call #header("Content-Type: image/png"); // Set the content type appropriately curl_close($session); // And close the session die($image);

• POCO Best Practice

  - by Paul Johnson

  All, I have a series of domain objects (project is NHibernate based). Currently as per 'good practice' they define only the business objects, comprising properties and methods specific to each objects function within the domain. However one of the objects has a requirement to send an SMTP message. I have a simple SMTP client class defined in a separate 'Utilities' assembly. In order to use this mail client from within the POCO, I would need to hold a reference to the utilities assembly in the domain. My query is this... Is it a departure from best practice to hold such a reference in a POCO, for the purpose of gaining necessary business functionality. Kind Regards Paul J.

• Must I call super when I implement -scrollViewDidScroll: of UIScrollViewDelegate in an UITableView?

  - by mystify

  I made a custom UITableView subclass and implemented this: - (void)scrollViewDidScroll:(UIScrollView *)scrollView { // scrolled... } Now, what I think is that UITableView may also love to get this message for some obvious reasons. However, when I don't forward that to super, for some reason, everything still works fine. Must I forward that guy to super? I mean...it's a delegate method implementation, but as far as I'm aware of, this would still override anything implemented in UITableView, or not? Edit: I see...the delegate could be anyone. Never mind about this. BUT: What I have such a thing in a superclass, and make a subclass. How would I even know that the superclass does implement that method and I must forward it to super?

• Comparison between Tigase, Openfire and any other open-source XMPP servers

  - by John

  I've been looking at these too, both seem to provide fully functional XMPP servers in Java. I know Tigase is designed in a very modular way, not looked at Openfire in as much detail yet. My intended use would be to create a custom IM-based app, using XMPP for convenience rather than to open my server up to talk to other XMPP servers. I'm trying to evaluate my needs based on the following, roughly in order of importance: Documentation coverage & community How easy to plug in own functionality Licensing/cost - I don't plan to release my code Maturity and stability

• Accessing original WordPress blog's DB from sub-blogs in network mode

  - by aendrew

  I'm helping with a university radio station website that runs WordPress and was recently switched over to Network (Multi-site/multi-user) mode by myself. The setup is as such: The parent site (www.stationID.com) runs a bunch of custom-built plugins to construct things like the show schedule calendar, the "Now Playing" widget, podcast list, et cetera. The new network websites ("wiki.stationID.com", "buddypress.stationID.com" for instance) run the same template as the parent site, but it stops after rendering the first section because the widgets from point 1 grab data from the main site's database that is not available to sub-blogs. My question is: how do I get data from the main site's tables on the sub-domain sub-blogs? A related question is: how do I set the $wpdb->prefix to be the same as the parent site on the child websites without it negatively effecting how the child website pulls data from its own database? Any help would be awesome, thanks!

• Silverlight File download from client

  - by luke

  I have a Silverlight application that implements some basic CRUD operations on a fairly flat data set. The application loads all the data onto the client to allow for quick editing (this is a fairly small data set no more that a couple K). I would like to allow them to download the file as a CSV so they can edit the data locally. I know i can set up a HyperLink button to a URL on my webserver and then server the data dynamically using a custom server handler. But this seems kind of roundabout to me because the all the data is already all on the Client's machine (because the Silverlight application loaded it). So i was wondering if there was a way to prompt the user for a file download and then dynamically generate the file download stream from Silverlight?

• Modal MessageBox for ASP.NET without jQuery

  - by Joe

  I have an assembly with custom ASP.NET server controls that is used in several, mostly in-house, ASP.NET 2.0 applications. The server controls use simple modal popup messageboxes, which are currently implemented using the javascript alert and confirm functions. I want to release a new version of this assembly that uses a better solution for messageboxes, including support for Yes/No buttons. The appearance would be something like a simplified version of the Ajax Control Toolkit ModalPopup extender (sample here). My constraints are that this should be as easy as possible to integrate into existing ASP.NET 2.0 applications without introducing new dependencies: ideally just drop in a new version of the assembly, that contains all the javascript it needs as an embedded resource, and possibly a CSS file. Because of this constraint, I am not considering solutions I've seen that use jquery, or the ASP.NET Ajax Control Toolkit, which appears to require adding elements to pages that use the extenders (ScriptManagers and the like). Any recommendations?

• registering httpModules in web.config

  - by Praesagus

  I am trying to register a custom HttpHandler in the web.config file. MSDN's example shows an entry that is commented out...um which doesn't work so well. When I uncomment I receive a Could not load file or assembly 'HttpModule.cs' or one of its dependencies. The system cannot find the file specified. error. The file name is HttpModule.cs and the class name is MyHttpModule. There is no explicit namespace yet. <httpModules> <add name="MyHttpModule" type="MyHttpModule, HttpModule" /> <httpModules> I am sure I am overlooking the obvious. Do I need to specify the file path somewhere? Thanks in advance.

• IPhone Plain TableView Section Header Image and Getting Text on Two Lines

  - by jp

  Hello, this is my first question, so if I didn't do the tags correctly, I'm sorry. I tried... Well here is my question: I am hoping someone can tell me how to do a 2-line section header for a plain tableview. The problems I am having are: 1) I cannot find an image that will mimic that of the default 1-line section header. Can someone share one with me, or tell me how I can find one? 2) I cannot seem to get the section header text on two lines, since I am pulling it from the fetched results controller, a "field" (sorry if wrong terminology) that I custom defined on the class for my table. So this "field" has multiple field values in it, and I have no way to take them apart... Any help would be appreciated.

• Flex ProgressBar component problem

  - by Abhinav

  I am trying to use the ProgressBar Flex component inside a custom Actionscript 3.0 component derived from the UIComponent class. I have set the minimum and maximum values etc. _progressBar = new ProgressBar(); _progressBar.label = "Loading"; _progressBar.minimum = 0; _progressBar.maximum = 100; _progressBar.direction = ProgressBarDirection.RIGHT; _progressBar.mode = ProgressBarMode.MANUAL; The component shows the "Loading" text but not the loading bar. Anything like _progressBar.setProgress(20, 100) does not have any effect on the code. Any ideas why this is not working?

• Silverlight 4: How to find ContextMenu' s Parent Control from menuitem_click?

  - by funwithcoding

  I have a datagrid and I added silverlight 4 toolkit contextmenu to textbox in datagrid as follows. When users right click on the textbox, contextmenu is being displayed. When users click the menu item with Header "Test", "MenuItem_Click" is getting executed. Now I want to access the textbox from the MenuItem_Click and modify its properties like background etc. Is there anyway to find textbox element(which is contextmenu's parent) from MenuItem_Click event? <my:DataGridTemplateColumn.CellTemplate> <DataTemplate> <TextBox Text="{Binding AcctId}" Style="{StaticResource documentTextBoxStyle}" ToolTipService.ToolTip="Right Click to modify parameters" > <toolkit:ContextMenuService.ContextMenu > <toolkit:ContextMenu > <toolkit:MenuItem Header="Test" Click="MenuItem_Click"/> </toolkit:ContextMenu> </toolkit:ContextMenuService.ContextMenu> </TextBox> </DataTemplate>

When I step through the type converter ConvertFrom code, it runs as expected. I don't even know were to start looking for an issue like this.
