  • My Android ListView item layout looks terrible

    - by jnylen
    I wanted to create a layout like the CyanogenMod call log in that there is a list item and a call button on the left which gets focus separately (screenshot). Instead, I get this mess. Here's my code: <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:minHeight="?android:attr/listPreferredItemHeight" android:layout_width="fill_parent" android:layout_height="fill_parent" android:paddingLeft="4dip" > <DontPressWithParentImageView android:id="@+id/play_icon" android:layout_width="wrap_content" android:layout_height="fill_parent" android:paddingLeft="14dip" android:paddingRight="14dip" android:layout_alignParentRight="true" android:gravity="center_vertical" android:src="@drawable/sym_play" android:background="@drawable/play_background" /> <View android:id="@+id/divider" android:layout_width="1px" android:layout_height="fill_parent" android:layout_marginTop="5dip" android:layout_marginBottom="5dip" android:layout_toLeftOf="@id/play_icon" android:layout_marginLeft="2dip" android:background="@drawable/divider_vertical_dark" /> <TextView android:id="@+id/file_info" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_marginBottom="8dip" android:layout_marginTop="-10dip" android:layout_marginLeft="10dip" android:layout_alignWithParentIfMissing="true" android:singleLine="true" android:ellipsize="marquee" android:textAppearance="?android:attr/textAppearanceSmall" android:textStyle="bold" /> <TextView android:id="@+id/file_title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_above="@id/file_info" android:layout_alignWithParentIfMissing="true" android:layout_marginBottom="-10dip" android:layout_marginLeft="4dip" android:textAppearance="?android:attr/textAppearanceLarge" android:singleLine="true" android:ellipsize="marquee" android:gravity="center_vertical" /> </RelativeLayout> For reference, the code I started with is here and here, and the source to DontPressWithParentImageView is here (but as you can see from my screenshot, that part is working). What am I doing wrong?

  • Using ThreadPool.QueueUserWorkItem in ASP.NET in a high traffic scenario

    - by Michael Hart
    I've always been under the impression that using the ThreadPool for (let's say non-critical) short-lived background tasks was considered best practice, even in ASP.NET, but then I came across this article that seems to suggest otherwise - the argument being that you should leave the ThreadPool to deal with ASP.NET related requests. So here's how I've been doing small asynchronous tasks so far: ThreadPool.QueueUserWorkItem(s => PostLog(logEvent)) And the article is suggesting instead to create a thread explicitly, similar to: new Thread(() => PostLog(logEvent)){ IsBackground = true }.Start() The first method has the advantage of being managed and bounded, but there's the potential (if the article is correct) that the background tasks are then vying for threads with ASP.NET request-handlers. The second method frees up the ThreadPool, but at the cost of being unbounded and thus potentially using up too many resources. So my question is, is the advice in the article correct? If your site was getting so much traffic that your ThreadPool was getting full, then is it better to go out-of-band, or would a full ThreadPool imply that you're getting to the limit of your resources anyway, in which case you shouldn't be trying to start your own threads? Clarification: I'm just asking in the scope of small non-critical asynchronous tasks (eg, remote logging), not expensive work items that would require a separate process (in these cases I agree you'll need a more robust solution).

  • SDL doesn't detect Arrow Keys

    - by Scott
    I am working through the SDL tutorials over at http://lazyfoo.net/SDL_tutorials/index.php and I'm stuck on tutorial 8 where I'm working with key presses. I'm using the following code: //Our Main application loop while(!quit){ if(SDL_PollEvent(&curEvents)){ if(curEvents.type == SDL_QUIT){ quit = true; } //If a key was pressed if( curEvents.type == SDL_KEYDOWN ) { //Set the proper message surface switch( curEvents.key.keysym.sym ) { case SDLK_UP: message = upMessage; break; case SDLK_DOWN: message = downMessage; break; case SDLK_LEFT: message = leftMessage; break; case SDLK_RIGHT: message = rightMessage; break; default: message = TTF_RenderText_Solid(font, "Unknown Key", textColor); break; } } } if( message != NULL ) { //Apply the background to the screen applySurface( 0, 0, background, screen ); //Apply the message centered on the screen applySurface( ( SCREEN_WIDTH - message->w ) / 2, ( SCREEN_HEIGHT - message->h ) / 2, message, screen ); //Null the surface pointer message = NULL; } //Update the screen if( SDL_Flip( screen ) == -1 ) { return 1; } } Where works fine, the default case is reached, for everything BUT pressing the arrow keys. I was wondering if someone could spot what I'm doing wrong.

  • Alternating table row colors in freemarker

    - by itsadok
    What's a good, simple way to have alternate row coloring with freemarker? Is this really the best way? <#assign row=0> <#list items as item> <#if (row % 2) == 0> <#assign bgcolor="green"> <#else> <#assign bgcolor="red"> </#if> <tr style='background-color: ${bgcolor}'><td>${item}</td></tr> <#assign row = row + 1> </#list> I tried doing this: <#assign row=0> <#list items as item> <tr style='background-color: ${(row % 2) == 0 ? "green" : "blue"}'><td>${item}</td></tr> <#assign row = row + 1> </#list> But apparently you can't user the ternary operator in there. Note: I guess I should have mentioned it earlier, but I can't use css classes or javascript, since this HTML is going into an email message.

  • Best way to convert wpf triggers to silverlight?

    - by Stewart Armbrecht
    I have developed several custom controls in a wpf application that use triggers. what is the fastest way to convert the code so that I have a single code base that works both in the wpf application and the silverlight applicaiton. Here is a sample of the code: <Style x:Key="sButtonAction" TargetType="Button"> <!--<Setter Property="BitmapEffect" Value="{StaticResource BannerEffect}" />--> <Setter Property="Height" Value="25" /> <Setter Property="Margin" Value="4" /> <Setter Property="Cursor" Value="Hand" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="Button"> <Border x:Name="PART_Border" CornerRadius="10" BorderThickness="{StaticResource sBorderThicknessStandard}" BorderBrush="{StaticResource bColorBorder}" Background="{StaticResource ButtonActionBackground}"> <TextBlock x:Name="PART_TextBlock" Margin="5,2,5,2" HorizontalAlignment="Center" VerticalAlignment="Center" Foreground="White"> <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" /></TextBlock> </Border> <ControlTemplate.Triggers> <Trigger Property="IsMouseOver" Value="True"> <Setter TargetName="PART_TextBlock" Property="Foreground" Value="#990000"></Setter> </Trigger> <Trigger Property="IsPressed" Value="True"> <Setter TargetName="PART_Border" Property="Background" Value="{StaticResource ButtonActionBackgroundSelected}"></Setter> </Trigger> </ControlTemplate.Triggers> </ControlTemplate> </Setter.Value> </Setter> </Style>

  • Stop all sounds permanently in AS3

    - by Fahim Akhter
    Hi, I have a main swf which has sound on/off buttons. It has many SWF's which are loaded into different placeholders at different time. All of them have different sounds in them. In addition to that there is a music loop going on in the background. Now, this perticular swf lets call it Father will be placed in some swf later on. What I'm trying to do right now is when the sound off button is pressed turn off all the sounds permanently so the child swf's and their sounds stop too. I have found a way in AS2 : global = new Sound( ) //no movie clip target path. and add the following code to your off button. on(release){ global.setVolume(0); //mutes all sound } and for on button on(release){ global.setVolume(100); //un mutes all sound } which ofcourse does not work for AS3. So how can I stop all sounds permanently in AS3? Secondly what if I have one sound (my background loop) which I want to keep going on. Would be a lot of help, been searching for a while now without a appropriate answer.

  • configure batch to sent minute info instead of entire stdout

    - by Daniel
    Hi all, I am working on a RedHat server along with several other users. We use the batch utility to set a job queue. Some of the programs that I use write stuff to stdout during the run, with info on who much data has been processed to far and estimated time until completion etc. batch -q z at> myScript -i somefile -o someotherfile By default, the batch util send an email to me (since I configured it using .forward) with the entire output from stdout. Since the scripts writes something to stdout a few times each second, the amount of log-stuff I get from a two-day script can be ˜20 Mbs. Clearly not what I want. I can of course pipe stdout to a file like so batch -q z at> myScript -i somefile -o someotherfile > myscript.stdout.log but then I get a blank e-mail from the util. So to my question: Is it possible to configure batch so that it sends time the job started and ended, or run time or some oth valuable information to me, instead of a 20 Mb mail or a blank mail? Note that the scripts that I use are binaries and I cannot customize the code to output less info in the first place (which would be the optimal solution I guess). Thanks /Daniel

  • How to determine if a ResourceDictionary is loaded correctly

    - by akaphenom
    How can I tell (through the debugger if my app resources are being loaded correctly). I have tried (in f#) type MyApp() as this = inherit Application() do Application.LoadComponent(this, new System.Uri("/FSSilverlightApp;component/App.xaml", System.UriKind.Relative)) let cc = new ContentControl() let mainGrid : Grid = loadXaml("MainWindow.xaml") let siteTemplate : Grid = mainGrid let txt : TextBlock = siteTemplate ? txt do this.Startup.Add(this.startup) let mutable s = "Items: " s <- s + this.Resources.Count.ToString() it is returning a count of zero. Though I am pretty sure the application is loading the resource because if I change the path within the App.xaml - I get exceptions at runtime. Other re,lavent snippets are: I have the following app.xaml <Application xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="Module1.MyApp"> <Application.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="/FSSilverlightApp;component/TransitioningFrame.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources> </Application> and content template: < ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:navigation="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Navigation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <ControlTemplate x:Key="TransitioningFrame" TargetType="navigation:Frame"> <Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"> <ContentPresenter Cursor="{TemplateBinding Cursor}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Content="{TemplateBinding Content}"/> </Border> </ControlTemplate> </ResourceDictionary>

  • Scrollable list items in jQuery

    - by Giles B
    Hi Guys, I have a list of 4 items and the ul has a background image that makes the second item look as though it has an arrow behind it. I want to be able to scroll the items up or down when they are clicked to the second items position so for example when I click the fourth item the whole list scrolls up so the fourth item is then postioned over the top of the background image and all the other items will be sitting in the same order above it. I have tried using jQuery Tools with the circular option selected but it clones the first an last item and i end up with a gap when i get to the bottom and I also cant make each item selectable to scroll the list up or down. Here is the code for the list <div id="priceGuide"> <ul id="priceRegion"> <li><a href="#">North & Midlands</a></li> <li><a href="#">London, north of the river</a></li> <li><a href="#">London, south of the river</a></li> <li><a href="#">South & South East</a></li> </ul><!-- /priceRegion --> </div><!-- /priceGuide --> Any help is most appreciated. Thanks Giles

  • Front End Developer v/s PHP-MySQL Engineer

    - by user301943
    Hello, I want to decide which of this would be a more viable career option? I am ready to quit my current job and hence I am looking for new opportunity. Current job is maintainence and no more active development. My current role is of a PHP/MySQL Developer. I very well understand web-programming and am comfortable with RoR/Sinatra/Zend MVC/JQuery/JSON manipulation, etc. I understand MySQL InnoDB/MyISAM engine and how one differs from the other, etc. Basically, I could very well manage the deployment of a web-application end-to-end including configuration of Apache/Nginx servers, memcache,etc On the other hand, I am being offered a Sr.Front End Web developer that would require me to extensively write HTML/CSS crossbrowser/crossplatform compliant code. I very well understand XHTML/CSS/Box model etc. I would be working on Drupal for the management of websites. While I understand continuing to work on server-side technologies would always be a good career path, how would the role of Core front-end developer turn out to be? If I take this opportunity, will I eventually get a chance to focus onto UCD, HCI, Information Architect,etc. So are these kinda roles possible if I focus on front end development? No offenses to the Front end developers, just want to understand if this is something I want to gain a mastery over. I have 2 yrs of industry experience after graduating with a MS-Computer Science. Although, I have a CS degree, if I were to take uip serious front-end role; I could probably go back and take up some design/HCI/UI courses. Please advise.

  • Integrating a Custom Compiler with the Visual Studio IDE

    - by M.A. Hanin
    Background: I want to create a custom VB compiler, extending the "original" compiler, to handle my custom compile-time attributes. Question: after I've created my custom compiler and I've got an executable file capable of compiling VB code via the standard command-line interface, how do I integrate this compiler with the Visual Studio IDE? (such that pressing "compile" or "build" will make use of my compiler instead of the default compiler). EDIT: (Correct me if i'm wrong) From the reactions here, I see this question is a bit shocking, so I shall further explain my needs and background: .NET provides us with a great mechanism called Attributes. As far as I understand, making attributes apply their intended behavior upon the attributed element (assembly, module, class, method, etc.) - attributes must be reflected upon. So the real trick here is reflecting and applying behavior at the right spot. Lets take Serialization for example: We decorate a class with the Serializable attribute. We then pass an instance of the class to the formatter's Serialize method. The formatter reflects upon the instance, checking if it has the Serializable attribute, and acting accordingly. Now, if we examine the Synchronization, Flags, Obsolete and CLSCompliant attributes, then the real question is: who reflects upon them? At least in some cases, it has to be the compiler (and/or IDE). Therefore, it seems that if I wish to create custom attributes that change an element's behavior regardless of any specific consumer, i must extend the compiler to reflect upon them at compilation. Of course, these are not my personal insights: the book "Applied .NET Attributes" provides a complete example of creating a custom attribute and a custom C# compiler to reflect upon that attribute at compilation (the example is used to implement "java-style checked exceptions").

  • How important is managing memory in Objective-C?

    - by Alex Mcp
    Background: I'm (jumping on the bandwagon and) starting learning about iPhone/iPad development and Objective-C. I have a great background in web development and most of my programming is done in javascript (no libraries), Ruby, and PHP. Question: I'm learning about allocating and releasing memory in Objective-C, and I see it as quite a tricky task to layer on top of actually getting the farking thing to run. I'm trying to get a sense of applications that are out there and what will happen with a poorly memory-managed program. A) Are apps usually released with no memory leaks? Is this a feasible goal, or do people more realistically just excise the worst offenders and that's ok? B) If I make an NSString for a title of a view, let's say, and forget to deallocate it it, does this really only become a problem if I recreate that string repeatedly? I imagine what I'm doing is creating an overhead of the memory needed to store that string, so it's probably quite piddling (a few bytes?) However if I have a rapidly looping cycle in a game that 'leaks' an int every cycle or something, that would overflow the app quite quickly. Are these assumptions correct? Sorry if this isn't up the community-wiki alley, I'm just trying to get a handle on how to think about memory and how careful I'll need to be. Any anecdotes or App Store-submitted app experiences would be awesome to hear as well.

  • Automatically support new changes with Python.

    - by Zachary Brown
    I was working on a program,that I need to support new additions. Hmmm. Let me give you some background on the program. It is an educational software program that has quizzes for the user to take, just to gain odd knowledge. Now, It currently supports 6 subjects, all organized with directores on the HDD ( i.e. the Science directory is called science. ) and the way you launch the subject to see what quizzes you have to take is by pushing a button on the home screen. This sort of thing prevents easy subject additions. I want to be able to add a subject later on without having to recode the home screen and re organize all the buttons. I would use a Listbox and os.listdir(...), but I was kind of wanting something prettier than a Listbox. I am using Tkinter on Windows. The Python version I am using is 2.6 Is there a "fancy" listbox sort of thing that can be styled to work with the background?

  • Can push technology / comet be faked?

    - by stef
    Client has a dating site and would like to have a popup (either a nice javascript overlay or a new browser window popup. we're flexible.) displayed to users when another user is visiting their page. I'm familiar with push technology and Comet but it's quite challenging to implement this and may place serious strain on a server with over 100,000 unique visitors per day. I'm wondering if there is a way of faking this, perhaps by not being accurate to the second. I can't really think of any way. This is a classic LAMP environment. Anyone? EDIT: what about this: placing an iframe on the page that refreshes every few seconds and at each page load it checks in the db if a visitor has been logged on this profile page. if so, it shows a message. the message would be visible but the background of the iframe would blend in with the background of the site and be invisible. if the message fades in and out, it would look like a JS box "popping up".

  • Tools for Maintaining Branches in SVN

    - by Chris Conway
    My team uses SVN for source control. Recently, I've been working on a branch with occasional merges from the trunk and it's been a fairly annoying experience (cf. Joel Spolsky's "Subversion Story #1"), so I've been looking alternative ways to manage branches and merging. Given that a centralized SVN repository is non-negotiable, what I'd like is a set of tools that satisfy the following conditions. Complete revision history should be stored in SVN for both trunk and branches. Merging in either direction (and potentially criss-crossing) should be relatively painless. Merging history should be stored in SVN to the greatest extent possible. I've looked at both git-svn and bzr-svn and neither seems to be up to the job—basically, given the revision history they can export from the SVN repository, they can't seem to do any better a job handling merges than SVN can. For example, after cloning the repository with git, the revision history for my branch shows the original branch off of trunk, but git doesn't "see" any of the interim SVN merges as "native" merges—the revision history is one long line. As a result, any attempts to merge from trunk in git yield just as many conflicts as an SVN merge would. (Besides, the git-svn documentation explicitly warns against using git to merge between branches.) Is there a way to adjust my workflow to make git satisfy the above requirements? Maybe I just need tips or tricks (or a separate merging tool?) to help SVN be better at merging into branches?

  • Accommodating hierarchical data in SQL Server 2005 database design

    - by Remnant
    Context I am fairly new to database design (=know the basics) and am grappling with how best to design my database for a project I am currently working on. In short, my database will keep a log of which employees have attended certain health and safety courses throughout the year. There are multiple types of course e.g. moving objects, fire safety, hygiene etc. In terms of my database design I need to accommodate the following: Each location can have multiple divisions Each division can have multiple departments Each department can have multiple functions Each function can have multiple job roles Each job role can have different course requirements Also note that the structure at each location may not be the same e.g. the departments within divisions are not the same across locations and the functions within departments may also differ. Edit - updated to better articulate problem Let's assume I am just looking at Location, Division and Department and I have my database as follows: LocationTable DivisionTable DepartmentTable LocationID(PK) DivisionID(PK) DepartmentID(PK) LocationName DivisionName DepartmentName There is a many-to-many relationship between Locations and Divisions and also between Departments and Divisions. Suppose I set up a 'Junction Table' as follows: Location_Division LocationID(FK) DivisionID(FK) Using Location_Division I could easily pull back the Divisions for any Location. However, suppose I want to pull back all departments for a given Division in a given Location. If I set up another 'Junction Table' for Division and Department then I can't see how I would differentiate Division by Location? Division_Department DivisionID(FK) DepartmentID(FK) Location_Division Division_Department LocationID DivisionID DivisionID DepartmentID 1 1 1 1 1 2 1 2 2 1 2 1 2 2 2 2 Do I need to expand the number of columns in my 'Junction Table' e.g. Location_Division_Department LocationID(FK) DivisionID(FK) DepartmentID(FK) Location_Division_Department LocationID DivisionID DepartmentID 1 1 1 1 1 2 1 1 3 2 1 1 2 1 2 2 1 3

  • Strategies for Accessing a Application with a COM API From PHP

    - by Alan Storm
    Background: Experienced PHP developer with a mostly *nix background. I'm writing a PHP application that needs to interact with a proprietary 3rd party system. The 3rd party system is Windows only. The PHP application will be living on a separate Linux based system The 3rd party application has been described as having a "COM API" that I'll need to talk to from the PHP application. What does this look like architecturally speaking? I'm starting with the COM section of the PHP manual, but I have specific questions. Specific Questions: Can I talk directly to a COM API from a PHP application running on another server? If so, how? (what PHP extensions would I need, or what protocols/PHP functions would I be using to talk to the API) If the answer to number 2 is no, I'd assume I'd need some kind of application on the Windows machine that can talk to COM, and then a service on the windows machine I can hit with PHP. Are there prebuilt frameworks for this kind of thing? Is this all nonsense and/or did I say something exceedingly stupid? (Quite possible, as I'm a little fuzzy on what "COM" does and doesn't cover) I'm obviously not looking for a full solution here, I'm just trying to get a general idea of what is and isn't possible and what kind of things I'll want to Google for. Thanks!

  • WPF ComboBox TemplateBinding to selected value

    - by Greg R
    I'm trying to create an editable textbox via a drop down of selected values. Basically in Red Only mode I want the drop down to be a disabled textbox. It works fine when I do this with SelectedValue but when I need it to display the dropdown text and not the value. This is what I have: <Style x:Key="EditableDropDownValueOnly" TargetType="ComboBox"> <Setter Property="Width" Value="Auto" /> <Setter Property="FontSize" Value="11" /> <Setter Property="HorizontalAlignment" Value="Left" /> <Setter Property="FontFamily" Value="Verdana" /> <Setter Property="MinWidth" Value="25" /> <Style.Triggers> <Trigger Property="IsReadOnly" Value="True"> <Setter Property="Background" Value="#FFFFFF" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="ComboBox"> <TextBox Text="{TemplateBinding SelectedItem, Converter={StaticResource StringCaseConverter}}" BorderThickness="0" Background="Transparent" FontSize="{TemplateBinding FontSize}" HorizontalAlignment="{TemplateBinding HorizontalAlignment}" FontFamily="{TemplateBinding FontFamily}" Width="{TemplateBinding Width}" TextWrapping="Wrap"/> </ControlTemplate> </Setter.Value> </Setter> </Trigger> </Style.Triggers> </Style> SelectedItem is a KeyValuePair, since my drop down is bound to a dictionary. I'm trying to display the "Value" element in my template. Is that possible? Thanks a lot!

  • Blurry UILabel as programmatic subview of UITableViewCell contentView

    - by Alex Reynolds
    I am adding a UILabel instance as a subview of my custom UITableViewCell instance's contentView. When I select the cell, the row is highlighted blue, except for the background of the label. The label text is sharp. When I set the label and content view backgroundColor property to [UIColor clearColor], the label text becomes blurry. How do I set the label background color to be clear, to allow the row highlight to come through, while still keeping the label text sharp? One suggestion I read elsewhere was to round the label's frame values, but this did not have any effect. CODE Here is a snippet of my custom UITableViewCell subview's -setNeedsLayout method: UILabel *_objectTitleLabel = [[UILabel alloc] initWithFrame:CGRectNull]; _objectTitleLabel.text = [self.awsObject cleanedKey]; _objectTitleLabel.font = [UIAppDelegate defaultObjectLabelFont]; _objectTitleLabel.highlightedTextColor = [UIColor clearColor]; //[UIAppDelegate defaultLabelShadowTint]; _objectTitleLabel.backgroundColor = [UIColor clearColor]; //[UIAppDelegate defaultWidgetBackgroundTint]; _objectTitleLabel.frame = CGRectMake( kCellImageViewWidth + 2.0 * self.indentationWidth, 0.5 * (self.tableView.rowHeight - 1.5 * kCellLabelHeight) + kCellTitleYPositionNudge, contentViewWidth, kCellLabelHeight ); _objectTitleLabel.frame = CGRectIntegral(_objectTitleLabel.frame); _objectTitleLabel.tag = kObjectTableViewCellTitleSubviewType; //NSLog(@"_objectTitleLabel: %@", NSStringFromCGRect(_objectTitleLabel.frame)); [self.contentView addSubview:_objectTitleLabel]; [_objectTitleLabel release], _objectTitleLabel = nil; ... self.contentView.backgroundColor = [UIAppDelegate defaultWidgetBackgroundTint]; self.contentView.clearsContextBeforeDrawing = YES; self.contentView.autoresizesSubviews = YES; self.contentView.clipsToBounds = YES; self.contentView.contentMode = UIViewContentModeRedraw;

    This is the input string 23x * y34x2. I want to insert " * " (star surrounded by whitespaces) after every number followed by letter, and after every letter followed by number. So my input string would look like this: 23 * x * y * 34 * x * 2. This is the regex that does the job: @"\d(?=[a-z])|a-z". This is the function that I wrote that inserts the " * ". Regex reg = new Regex(@"\d(?=[a-z])|[a-z](?=\d)"); MatchCollection matchC; matchC = reg.Matches(input); int ii = 1; foreach (Match element in matchC)//foreach match I will find the index of that match { input = input.Insert(element.Index + ii, " * ");//since I' am inserting " * " ( 3 characters ) ii += 3; //I must increment index by 3 } return input; //return modified input My question how to do same job using .net MatchEvaluator? I'am new to regex and don't understand good replacing with MatchEvaluator. This is the code that I tried to wrote: Regex reg = new Regex(@"\d(?=[a-z])|[a-z](?=\d)"); MatchEvaluator matchEval = new MatchEvaluator(ReplaceStar); input = reg.Replace(input, matchEval); return input; } public string ReplaceStar( Match match ) { //return What?? }

  • Trigger for ComboBox in Silverlight

    - by Budda
    Is there any possibility to display selected item of the ComboBox (after popup closing) in a way that is different from its displaying in DropDown List (There are players number and name in the dropdown list, but after list closing I want to see only its number). How can I change a background for the player with some Flag? As far as I know, all of that can be done with triggers, but are they supported in Silverlight 4, VS2010, Silverlight Toolkit 4? In my case the following code <ComboBox ItemsSource="{Binding PlayersAll}" SelectedItem="{Binding Path=SelectedPlayer, Mode=TwoWay}" > <ComboBox.ItemTemplate> <DataTemplate> <ToolkitControls:WrapPanel Orientation="Horizontal"> <TextBlock Text="{Binding TeamNumber}"/> <TextBlock Text=" - "/> <TextBlock Text="{Binding ShortName}"/> </ToolkitControls:WrapPanel> <DataTemplate.Triggers> <Trigger Property="HasError" Value="True"> <Setter Property="Background" TargetName="FlagSet" Value="Red"/> </Trigger> </DataTemplate.Triggers> </DataTemplate> </ComboBox.ItemTemplate> </ComboBox> gives an error: The property 'Triggers' does not exist on the type 'DataTemplate' in the XML namespace 'http://schemas.microsoft.com/winfx/2006/xaml/presentation' what is wrong here? Here are my namespaces: xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:navigation="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Navigation" xmlns:data="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Data" xmlns:ToolkitControls="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Toolkit"

  • Single-player pong game

    - by Jam
    I am just starting out learning pygame and livewires, and I'm trying to make a single-player pong game, where you just hit the ball, and it bounces around until it passes your paddle (located on the left side of the screen and controlled by the mouse), which makes you lose. However, I keep getting the error: "Cannot have more than on Screen object", which I can find no references to online really, and I can't make sense of it. I want to eventually make the game more complicated, but I need to make it work first. Help please! Here's the code so far: from livewires import games games.init(screen_width=640, screen_height=480, fps=50) class Paddle(games.Sprite): image=games.load_image("paddle.bmp") def __init__(self): super(Paddle, self).__init__(image=Paddle.image, y=games.mouse.y, left=0) self.score=games.Text(value=0, size=25, top=5, right=games.screen.width-10) games.screen.add(self.score) def update(self): self.y=games.mouse.y self.check_collide() def check_collide(self): for ball in self.overlapping_sprites: self.score.value+=1 self.score.right=games.screen.width-10 ball.handle_collide() class Ball(games.Sprite): image=games.load_image("ball.bmp") speed=1 def __init__(self, x, y=90): super(Ball, self).__init__(image=Ball.image, x=x, y=y, dx=Ball.speed, dy=Ball.speed) def update(self): if self.left<0: self.end_game() self.destroy() def handle_collide(self): if self.right>games.screen.width: self.dx=-self.dx if self.bottom>games.screen.height or self.top<0: self.dy=-self.dy def ball_destroy(self): self.destroy() def main(): background_image=games.load_image("background.bmp", transparent=False) games.screen.background=background_image the_ball=Ball() games.screen.add(the_ball) the_paddle=Paddle() games.screen.add(the_paddle) games.mouse.is_visible=False games.screen.event_grab=True games.screen.mainloop() main()

  • Call long running operation in WSS feature OnActivated Event

    - by dirq
    More specifically - How do I reference SPContext in Web Service with [SoapDocumentMethod(OneWay=true)]? We are creating a feature that needs to run a job when a site is created. The job takes about 4 minutes to complete. So, we made a web service that we can call when the feature is activated. This works but we want it to run asynchronously now. We've found the SoapDocumentMethod's OneWay property and that would work awesomely but the SPContext is now NULL. We have our web services in the _vti_bin virtual directory so it's available in each Windows Sharepoint Services site. I was using the SPContext.Current.Web to get the site and perform the long running operation. I wanted to just fire and forget about it by returning a soap response right away and letting the process run. How can I get the current SPContext? I used to be able to do this in my web service: SPWeb mySite = SPContext.Current.Web; Can I get the same context when I have the [SoapDocumentMethod(OneWay=true)] attribute applied to my web service? Or must I recreate the SPWeb from the url? This is similar to this thread: http://stackoverflow.com/questions/340192/webservice-oneway-and-new-spsitemyurl Update: I've tried these two ways but they didn't work: SPWeb targetSite = SPControl.GetContextWeb(this.Context); SPWeb targetSite2 = SPContext.GetContext(this.Context).Web;
