  • Windows Phone 7 ListBox uncustomizable?

    - by Roy
    I've just recently started development using Visual Studio 2010 Express for Windows Phone and I put in a ListBox. I can't seem to manipulate the formatting. No matter what I do, the background is black/gray, the selected items have a blue border, and there is padding between the items in the listbox (i'm using images). Here is my code: Xaml: <Grid x:Name="ContentGrid" Grid.Row="1"> <Grid Name="gallery"> <Grid.RowDefinitions> <RowDefinition Height="370" /> <RowDefinition Height="150" /> </Grid.RowDefinitions> <Border BorderBrush="Red" Width="450" CornerRadius="4" BorderThickness="2" Background="Red" Margin="10,30,20,10" Padding="6,6,6,6"> <Image Grid.Row="0" Grid.Column="0" Height="360" x:Name="imgPreview"/> </Border> <ListBox x:Name="lbScrollGallery" Grid.Row="1" Grid.Column="0" Padding="0" VerticalAlignment="Top" Width="450" SelectionChanged="ScrollerSelectionChanged" d:LayoutOverrides="HorizontalAlignment" ScrollViewer.HorizontalScrollBarVisibility="Hidden"> <ListBox.ItemsPanel> <ItemsPanelTemplate> <StackPanel Orientation="Horizontal"/> </ItemsPanelTemplate> </ListBox.ItemsPanel> <ListBox.ItemTemplate> <DataTemplate> <Image Width="100" Height="100" Stretch="Fill" Name="imgSource" VerticalAlignment="Center" Source="{Binding Path=Url}" /> </DataTemplate> </ListBox.ItemTemplate> </ListBox> </Grid> </Grid> Is there some way I can customize the listbox? Like change the background to red or make the padding between different items 0?

  • How to change the margin of code's frame of showexpl.sty when numbers=none?

    - by suugaku
    Hi all, I want to align the code's frame with the formated text's frame. If the numbers=left,the mission is accomplished by configuring xleftmargin, xrightmargin, framesep, and numbersep. However, when I set numbers=none, I cannot accomplish my mission by configuring those properties. Regardless of the values set to those properties, the code's frame remains unchanged and expands beyond the \textwidth. Please see my code snippet below. Thank you in advance. \documentclass[a4paper,11pt,twoside,final,dvips]{book} \usepackage{xcolor} \usepackage{showexpl} \lstset{% breaklines=true, breakindent=0pt, basicstyle=\color{magenta}\ttfamily\tiny, keywordstyle=\color{blue}\sffamily\bfseries, identifierstyle=\color{black}, commentstyle=\color{cyan}\itshape, stringstyle=\rmfamily, showstringspaces=false, tabsize=2, %========== FRAME ========== frame=single, framerule=0.4pt, rulecolor=\color{red}, framesep=3pt, %========== MARGIN ========== xleftmargin=3.4pt, xrightmargin=3.4pt, %========== NUMBER ========== numbers=left, numberstyle=\color{red}\tiny, numbersep=6.4pt, explpreset={language={[LaTeX]TeX},pos=b}% } \usepackage{lipsum} \usepackage{printlen} %------------------------- MARKER ------------------------ \newlength{\halftextwidth} \setlength{\halftextwidth}{\textwidth*\real{0.5}} \newcommand*{\MARKER}% {% \uselengthunit{cm} \par\noindent\strut\vrule% \hrulefill~% {\color{red}\scriptsize half text area: \printlength{\halftextwidth}}% ~\hrulefill\vrule% \hrulefill~% {\color{red}\scriptsize half text area: \printlength{\halftextwidth}}% ~\hrulefill\vrule% \marginpar% {% \strut\vrule\hrulefill~% {\color{red}\scriptsize margin area: \rndprintlength{\marginparwidth}}% ~\hrulefill\vrule% }% \par% }% \begin{document} \chapter{I love \LaTeXe, but $\cdots$} \section{With numbers=left} \vfill \MARKER \begin{LTXexample} \lipsum[1-1] \end{LTXexample} \MARKER \vfill \pagebreak \section{With numbers=none} \vfill \MARKER % Any values that are assigned to xleftmargin or xrightmargin % have no effect on the margin of the code's frame. \begin{LTXexample}[numbers=none,xleftmargin=10.4pt,xrightmargin=10.4pt] \lipsum[1-1] \end{LTXexample} \MARKER \vfill \end{document}

  • JPA - Performance with using multiple entity manager

    - by Nguyen Tuan Linh
    My situation is: The code is not mine I have two kinds of database: one is Dad, one is Son. In Dad, I have a table to store JNDI name. I will look up Dad using JNDI, create entity manager, and retrieve this table. From these retrieved JNDI names, I will create multiple entity managers using multiple Son databases. The problem is: Son have thousands of entities. It takes each Son database around 10 minutes to load all entities. If there is 4 Son databases, it will be 40 minutes. My question: Is there any way to load all entities and use them for all entity manager? Please look at the code below For each Son JNDI: Map<String, String> puSonProperties = new HashMap<String, String>(); puSonProperties.put("javax.persistence.jtaDataSource", sonJndi); EntityManagerFactory emf = Persistence.createEntityManagerFactory("PUSon", puSonProperties); PUSon - All of them use the same persistence unit log.info("Verify entity manager for son: {0} - {1}", sonCode, emSon.find(Son_configuration.class, 0) != null ? "ok" : "failed!"); This is the actual code where the loading of all entities begins. 10 mins.

  • How do I relate tables with different foreign key names in Kohana ORM?

    - by Matt H
    I'm building a Kohaha application to manage sip lines in asterisk. I'm wanting to use ORM but I'm wondering how do relate certain tables that are already well established. e.g. the table sip_lines looks like this. +--------------------+------------------+------+-----+-------------------+-----------------------------+ | Field | Type | Null | Key | Default | Extra | +--------------------+------------------+------+-----+-------------------+-----------------------------+ | id | int(10) unsigned | NO | PRI | NULL | auto_increment | | sip_name | varchar(80) | NO | UNI | NULL | | | displayname | varchar(48) | NO | | NULL | | | line_num | varchar(10) | NO | MUL | NULL | | | model | varchar(12) | NO | MUL | NULL | | | mac | varchar(16) | NO | MUL | NULL | | | areacode | varchar(6) | NO | MUL | NULL | | | per_line_astpp_acc | tinyint(1) | NO | | 0 | | | play_warning | tinyint(1) | NO | | 0 | | | callout_disabled | tinyint(1) | NO | | 0 | | | notes | varchar(80) | NO | | NULL | | | last_update | timestamp | NO | | CURRENT_TIMESTAMP | on update CURRENT_TIMESTAMP | +--------------------+------------------+------+-----+-------------------+-----------------------------+ sip_buddies is this: +----------------+------------------------------+------+-----+-----------+----------------+ | Field | Type | Null | Key | Default | Extra | +----------------+------------------------------+------+-----+-----------+----------------+ | id | int(11) | NO | PRI | NULL | auto_increment | | name | varchar(80) | NO | UNI | | | | host | varchar(31) | NO | | | | | | | lastms | int(11) | NO | | 0 *** snip *** +----------------+------------------------------+------+-----+-----------+----------------+ The two tables are actually related as sip_lines.sip_name = sip_buddies.name How do I relate them in Kohana ORM as this wouldn't be quite right would it? <?php defined('SYSPATH') or die('No direct script access.'); /* A model for all the account information */ class Sip_Line_Model extends ORM { protected $has_one = array("sip_buddies"); } ?> EDIT: Actually, it'd be fair to say that these tables are not properly related with foreign keys! doh. EDIT: Looks like Kohana ORM is not that flexible. ORM is probably not the way to go and works best for completely new projects where the data model can be altered. The reason being that the key names must follow a specific naming convention or else they won't relate in Kohana.

  • Background worker not working right

    - by vbNewbie
    I have created a background worker to go and run a pretty long task that includes creating more threads which will read from a file of urls and crawl each. I tried following it through debugging and found that the background process ends prematurely for no apparent reason. Is there something wrong in the logic of my code that is causing this. I will try and paste as much as possible to make sense. While Not myreader.EndOfData Try currentRow = myreader.ReadFields() Dim currentField As String For Each currentField In currentRow itemCount = itemCount + 1 searchItem = currentField generateSearchFromFile(currentField) processQuerySearch() Next Catch ex As Microsoft.VisualBasic.FileIO.MalformedLineException Console.WriteLine(ex.Message.ToString) End Try End While This first bit of code is the loop to input from file and this is what the background worker does. The next bit of code is where the background worker creates threads to work all the 'landingPages'. After about 10 threads are created the background worker exits this sub and skips the file input loop and exits the program. Try For Each landingPage As String In landingPages pgbar.Timer1.Stop() If VisitedPages.Contains(landingPage) Then Continue For Else Dim thread = New Thread(AddressOf processQuery) count = count + 1 thread.Name = "Worm" & count thread.Start(landingPage) If numThread >= 10 Then For Each thread In ThreadList thread.Join() Next numThread = 0 Continue For Else numThread = numThread + 1 SyncLock ThreadList ThreadList.Add(thread) End SyncLock End If End If Next

  • how to force operating system to give java more memory?

    - by Denny
    Hello, I've got problem with java jar files and memory. I use netbeans 6.7 to develop an application and this application need more memory to run because it converts another files. Whenever this application convert a 6-10 mb file, it'll crash. So I set netbeans VM Options : -Xms32m -Xmx256m and the application can convert 6-10mb files with no problem. I Clean and Build the project so it can make a jar file of my application. I run the jar on my computer and use jconsole to monitor the memory. The maximum memory to use by the application shows 256 mb. But whenever I move it to some other computers, it shows 65-66 mb on jconsole and the application will crash when convert 6-10 mb files. So I need to use command prompt : java -jar -Xmx256m myjar.jar to execute the jar with maximum memory Why it can be happen, in my computer the maximum memory shows 256 mb but on another computer 65-66 mb? Can I force another computer to give extra maximum memory to my application? Thank you for your answer. I'm sorry for my inadequate English. If you all find my question is hard to understand, please let me know. Best Regards Denny ps: fyi the computer i used to develop the application have 2gb ram, on the other computers i tested have 1-2 gb ram.

  • Encoding h.264 with libavcodec/x264

    - by Leviathan
    I am attempting to encode video using libavcodec/libavformat. I'm trying to change the standard output-example.c from ffmpeg source. The AVI file is created on the disk, but the only sound is encoded. I tried adding a lot of options for x264 from here. All the other codecs works fine, mpeg2, mpeg4, mjpeg, xvid. In addition to specifying the parameters x264, I also set the codec to AVOutputFormat structure. That's all I've done. AVOutputFormat *pOutFormat; // in header file av_register_all(); AVCodec *codec = avcodec_find_encoder_by_name("libx264"); pOutFormat = guess_format("avi", NULL, NULL); pOutFormat->video_codec = codec->id; The debug output of my application: Output #0, mp4, to 'D:\1.avi': Stream #0.0: Video: libx264, yuv420p, 320x240, q=10-51, 500 kb/s, 90k tbn, 25 tbc Stream #0.1: Audio: aac, 44100 Hz, 1 channels, s16, 128 kb/s [libx264 @ 0x694010]using cpu capabilities: MMX2 SSE2Fast SSSE3 FastShuffle SSE4.2 [libx264 @ 0x694010]bitrate tolerance too small, using .01 [libx264 @ 0x694010]profile Main, level 2.0 [libx264 @ 0x694010]frame I:150 Avg QP:14.76 size: 2534 [libx264 @ 0x694010]mb I I16..4: 75.9% 0.0% 24.1% [libx264 @ 0x694010]final ratefactor: 17.57 [libx264 @ 0x694010]coded y,uvDC,uvAC intra: 42.7% 92.4% 47.4% [libx264 @ 0x694010]i16 v,h,dc,p: 11% 14% 2% 73% [libx264 @ 0x694010]i4 v,h,dc,ddl,ddr,vr,hd,vl,hu: 21% 18% 29% 5% 8% 10% 3% 3% 2% [libx264 @ 0x694010]kb/s:506.79

  • How to find Part Time development/IT work?

    - by Jonathan
    I've been working in the IT field now for 10 years. Originally trained as an Engineer, started out with C++ and have been a .Net specialist since beta. Currently seconded to a major city and working in the finance industry as freelance, I really feel like i've hit the glass ceiling. Have been contracting now for 5 years as the company politics and frustration of not being promoted and poor pay rises for excellent work but during the last decade of corporate cost cutting took its toll on my morale. Freelance made all the difference and i've had a very decorated career for good clients. What any Engineering student could ever dream of when starting out. The problem is, it doesn't particularly make me happy. It's good work, and i enjoy the problem solving aspects of it and having something to do each day. However there is always a large overhead of non-technical work and dealing with poor managers etc. I guess the Engineering was always a bit of a mistake i made the best out of, and now having 10 years behind a computer hasn't done wonders for my health or eye sight. In a nutshell i am in the process of retraining as a therapist and would like to open my own clinic. However, never having done this before, the fast pace IT skills outdate and the fact that all my experience and skills are non transferrable, i am a little worried. Any ideas how i can find part time IT work as i build up my business? (it's incredibly hard to find freelancing work that doesn't require long hours and overtime). Or other ideas to make the transition easier, and perhaps backout if it financially doesn't work/or i have enough marketing skills? I'd be interested to hear from people who have made a similar transition, successfully or unsuccessfully. Many thanks

  • How to determine the data type of a CvMat

    - by Chris
    When using the CvMat type, the type of data is crucial to keeping your program running. For example, depending on whether your data is type float or unsigned char, you would choose one of these two commands: cvmGet(mat, row, col); cvGetReal2D(mat, row, col); Is there a universal approach to this? If the wrong data type matrix is passed to these calls, they crash at runtime. This is becoming an issue, since a function I have defined is getting passed several different types of matrices. How do you determine the data type of a matrix so you can always access its data? I tried using the "type()" function as such. CvMat* tmp_ptr = cvCreateMat(t_height,t_width,CV_8U); std::cout << "type = " << tmp_ptr->type() << std::endl; This does not compile, saying "term does not evaluate to a function taking 0 arguments". If I remove the brackets after the word type, I get a type of 1111638032 EDIT minimal application that reproduces this... int main( int argc, char** argv ) { CvMat *tmp2 = cvCreateMat(10,10, CV_32FC1); std::cout << "tmp2 type = " << tmp2->type << " and CV_32FC1 = " << CV_32FC1 << " and " << (tmp2->type == CV_32FC1) << std::endl; } Output: tmp2 type = 1111638021 and CV_32FC1 = 5 and 0

  • LINQ Query please help C#.Net.

    - by Paul Matthews
    I'm very new to LINQ and struggling to find the answers. I have a simple SQL query. Select ID, COUNT(ID) as Selections, OptionName, SUM(Units) as Units FROM tbl_Results GROUP BY ID, OptionName. The results I got were: '1' '4' 'Approved' '40' '2' '1' 'Rejected' '19' '3' '2' 'Not Decided' '12' Due to having to encrypt all my data in the database I'm unable to do sums. Therefore I have now brought back the data and decrypt it in the application layer. Results would be: '1' 'Approved' '10' '3' 'Not Deceided' '6' '2' 'Rejected' '19' '1' 'Approved' '15' '1' 'Approved' '5' '3' 'Not Deceided' '6' '1' 'Approved' '10' using a simple class I have called back the above results, and put them in a list class. public class results { public int ID {get;set;} public string OptionName {get;set;} public int Unit {get;set;} } I almost have the LINQ query to bring back the results like the SQL query at the top var q = from r in Results group p.Unit by p.ID int g select new {ID = g.Key, Selections = g.Count(), Units = g.Sum()}; How do I ensure my LINQ query also give me the Option Name? Also if I created a class called Statistics to hold my results how would I modify the LINQ query to give me list result set? public class results { public int ID {get;set;} public int NumberOfSelections { get; set; } public string OptionName {get;set;} public int UnitTotal {get;set;} }

  • Planning management slots/sessions

    - by Glide
    I have a planning structure on two tables to store available slots by day, and sessions. A slot is defined by a range of time in the day. CREATE TABLE slot ( `id` int(11) NOT NULL AUTO_INCREMENT , `date` date , `start` time , `end` time ); Sessions can't overlap themselves and must be wrapped in a slot.

  • How to thoroughly purge and reinstall postgresql on ubuntu?

    - by John Mee
    Somehow I've managed to completely bugger the install of postgresql on Ubuntu karmic. I want to start over from scratch, but when I "purge" the package with apt-get it still leaves traces behind such that the reinstall configuration doesn't run properly. After I've done: apt-get purge postgresql apt-get install postgresql It said Setting up postgresql-8.4 (8.4.3-0ubuntu9.10.1) ...

Right this second, when I run that command "pg_createcluster..." it complains that '/var/lib/postgresql/8.4/main/postgresql.conf does not exist', so I'll go find one of those but I'm sure that won't be the end of it. Is there not some easy one-liner (or two) which will burn it completely and let me start over?

  • Using repaint() method.

    - by owca
    I'm still struggling to create this game : http://stackoverflow.com/questions/2844190/choosing-design-method-for-ladder-like-word-game .I've got it almost working but there is a problem though. When I'm inserting a word and it's correct, the whole window should reload, and JButtons containing letters should be repainted with different style. But somehow repaint() method for the game panel (in Main method) doesn't affect it at all. What am I doing wrong ? Here's my code: Main: import java.util.Scanner; import javax.swing.*; import java.awt.*; public class Main { public static void main(String[] args){ final JFrame f = new JFrame("Ladder Game"); Scanner sc = new Scanner(System.in); System.out.println("Creating game data..."); System.out.println("Height: "); //setting height of the grid while (!sc.hasNextInt()) { System.out.println("int, please!"); sc.next(); } final int height = sc.nextInt(); /* * I'm creating Grid[]game. Each row of game contains Grid of Element[]line. * Each row of line contains Elements, which are single letters in the game. */ Grid[]game = new Grid[height]; for(int L = 0; L < height; L++){ Grid row = null; int i = L+1; String s; do { System.out.println("Length "+i+", please!"); s = sc.next(); } while (s.length() != i); Element[] line = new Element[s.length()]; Element single = null; String[] temp = null; String[] temp2 = new String[s.length()]; temp = s.split(""); for( int j = temp2.length; j>0; j--){ temp2[j-1] = temp[j]; } for (int k = 0 ; k < temp2.length ; k++) { if( k == 0 ){ single = new Element(temp2[k], 2); } else{ single = new Element(temp2[k], 1); } line[k] = single; } row = new Grid(line); game[L] = row; } //############################################ //THE GAME STARTS HERE //############################################ //create new game panel with box layout JPanel panel = new JPanel(); panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS)); panel.setBackground(Color.ORANGE); panel.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10)); //for each row of the game array add panel containing letters Single panel //is drawn with Grid's paint() method and then returned here to be added for(int i = 0; i < game.length; i++){ panel.add(game[i].paint()); } f.setContentPane(panel); f.pack(); f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); f.setVisible(true); boolean end = false; boolean word = false; String text; /* * Game continues until solved() returns true.

  • python calendar to calculate month backwards

    - by Suhail
    Hi, we are trying to create a calendar function in python. we have created a small content management system, the requirement is, there will be a drop down list on the top right hand corner of the website, which will give the options - Months - 1 month, 2 months, 3 months and so on..., if the user selects 8 months then it should show the postscount for the last 8 months. the issue is we tried to write a small code which would do the month calculations, but the bug is that it does not consider the months beyond the current year, it shows the postscount only for months of the current year. for example: if the user selects 3 months, it will show the count for the l 3 months i.e present month and the previous 2 months, but if the user selects option more than 4 months, it does not consider the months from previous year, it still shows the month of the present year only. I am pasting the code below:- def __getSpecifiedMailCount__(request, value): dbconnector= DBConnector() CdateList= "select cdate from mail_records" DateNow= datetime.datetime.today() DateNow= DateNow.strftime("%Y-%m") DateYear= datetime.datetime.today() DateYear= DateYear.strftime("%Y") DateMonth= datetime.datetime.today() DateMonth= DateMonth.strftime("%m") #print DateMonth def getMonth(value): valueDic= {"01": "Jan", "02": "Feb", "03": "Mar", "04": "Apr", "05": "May", "06": "Jun", "07": "Jul", "08": "Aug", "09": "Sep", "10": "Oct", "11": "Nov", "12": "Dec"} return valueDic[value] def getMonthYearandCount(yearmonth): MailCount= "select count(*) as mailcount from mail_records where cdate like '%s%s'" % (yearmonth, "%") MailCountResult= MailCount[0]['mailcount'] return MailCountResult MailCountList= [] MCOUNT= getMonthYearandCount(DateNow) MONTH= getMonth(DateMonth) MailCountDict= {} MailCountDict['monthyear']= MONTH + ' ' + DateYear MailCountDict['mailcount']= MCOUNT var_monthyear= MONTH + ' ' + DateYear var_mailcount= MCOUNT MailCountList.append(MailCountDict) i=1 k= int(value) hereMONTH= int(DateMonth) while (i < k): hereMONTH= int(hereMONTH) - 1 if (hereMONTH < 10): hereMONTH = '0' + str(hereMONTH) if (hereMONTH == '00') or (hereMONTH == '0-1'): break else: PMONTH= getMonth(hereMONTH) hereDateNow= DateYear + '-' + PMONTH hereDateNowNum= DateYear + '-' + hereMONTH PMCOUNT= getMonthYearandCount(hereDateNowNum) MailCountDict= {} MailCountDict['monthyear']= PMONTH + ' ' + DateYear MailCountDict['mailcount']= PMCOUNT var_monthyear= PMONTH + ' ' + DateYear var_mailcount= PMCOUNT MailCountList.append(MailCountDict) i = i + 1 #print MailCountList MailCountDict= {'monthmailcount': MailCountList} reportdata = MailCountDict['monthmailcount'] #print reportdata return render_to_response('test.html', locals())

  • MySQL ORDER BY DESC is fast but ASC is very slow

    - by Pepper
    Hello, I'm completely stumped on this one. For some reason when I sort this query by DESC it's super fast, but if sorted by ASC it's extremely slow. This takes about 150 milliseconds: SELECT posts.id FROM posts USE INDEX (published) WHERE posts.feed_id IN ( 4953,622,1,1852,4952,76,623,624,10 ) ORDER BY posts.published DESC LIMIT 0, 50; This takes about 32 seconds: SELECT posts.id FROM posts USE INDEX (published) WHERE posts.feed_id IN ( 4953,622,1,1852,4952,76,623,624,10 ) ORDER BY posts.published ASC LIMIT 0, 50; The EXPLAIN is the same for both queries. id select_type table type possible_keys key key_len ref rows Extra 1 SIMPLE posts index NULL published 5 NULL 50 Using where I've tracked it down to "USE INDEX (published)". If I take that out it's the same performance both ways. But the EXPLAIN shows the query is less efficient overall. id select_type table type possible_keys key key_len ref rows Extra 1 SIMPLE posts range feed_id feed_id 4 \N 759 Using where; Using filesort And here's the table. CREATE TABLE `posts` ( `id` int(20) NOT NULL AUTO_INCREMENT, `feed_id` int(11) NOT NULL, `post_url` varchar(255) NOT NULL, `title` varchar(255) NOT NULL, `content` blob, `author` varchar(255) DEFAULT NULL, `published` int(12) DEFAULT NULL, `updated` datetime NOT NULL, `created` datetime NOT NULL, PRIMARY KEY (`id`), UNIQUE KEY `post_url` (`post_url`,`feed_id`), KEY `feed_id` (`feed_id`), KEY `published` (`published`) ) ENGINE=InnoDB AUTO_INCREMENT=196530 DEFAULT CHARSET=latin1; Is there a fix for this? Thanks!

  • How do I animate UserControl objects using Storyboard and DoubleAnimation?

    - by Neo
    In my WPF application, I have a Canvas object that contains some UserControl objects. I wish to animate the UserControl objects within the Canvas using DoubleAnimation so that they go from the right of the Canvas to the left of the Canvas. This is how I have done it so far (by passing the UserControl objects into the function): private void Animate(FrameworkElement e) { DoubleAnimation ani = new DoubleAnimation() { From = _container.ActualWidth, To = 0.0, Duration = new Duration(new TimeSpan(0, 0, 10), TargetElement = e }; TranslateTransform trans = new TranslateTransform(); e.RenderTransform = trans; trans.BeginAnimation(TranslateTransform.XProperty, ani, HandoffBehavior.Compose); } However, this doesn't allow me to pause the animation, so I have considered using a Storyboard instead to do this, but I'm not sure how to implement this. This has been my attempt so far: private void Animate(FrameworkElement e) { DoubleAnimation ani = new DoubleAnimation() { From = _container.ActualWidth, To = 0.0, Duration = new Duration(new TimeSpan(0, 0, 10), TargetElement = e }; Storyboard stb = new Storyboard(); Storyboard.SetTarget(ani, e); Storyboard.SetTargetProperty(ani, "Left"); stb.Children.Add(ani); stb.Begin(); } Of course, this fails as UserControl doesn't have a Left property. How can I achieve what I'm after? Thanks.

  • Why can't I Bind a viewmodel property to a dependency property of a custom control

    - by Robert
    I want to use a color picker in my wpf application and I saw a nice looking one on this codeproject page. The control works fine until I want to connect the control to a viewmodel. I created a small test program with this viewmodel: public class ColorViewModel : ViewModelBase { public ColorViewModel() { LineColor = Brushes.Yellow; } SolidColorBrush _brushColor; public SolidColorBrush LineColor { get { return _brushColor; } set { _brushColor = value; RaisePropertyChanged(() => LineColor); } } } The test program has a textbox and the colorpicker controls: <StackPanel Orientation="Horizontal"> <TextBlock Text="Please Select a Color" FontWeight="Bold" Margin="10" Foreground="{Binding Path=LineColor, UpdateSourceTrigger=PropertyChanged}"/> <vw:ColorPickerControlView x:Name="ForeColorPicker" Margin="10" CurrentColor="{Binding Path=LineColor, UpdateSourceTrigger=PropertyChanged }"/> </StackPanel> In the loaded event of the window I set the viewmodel to the datacontext like this: DataContext = new ColorViewModel(); The problem is that I can't seem to bind the LineColor property of the viewmodel to the CurrentColor property of the ColorPickerControlView. The CurrentControl property of the ColorPickerControlView seems to be fine. The constructor looks like this: public ColorPickerControlView() { this.DataContext = this; InitializeComponent(); CommandBindings.Add(new CommandBinding(SelectColorCommand, SelectColorCommandExecute)); } In the constructor of the UserControl there is the line this.DataContext = this; I read that is is necessary to bind the dependency properties. Do I override this line when I set my viewmodel to the datacontext and is that why I can't bind to the CurrentColor property? Is there any workaround? Or did I make another mistake?

  • Help me understand entity framework 4 caching for lazy loading

    - by Chris
    I am getting some unexpected behaviour with entity framework 4.0 and I am hoping someone can help me understand this. I am using the northwind database for the purposes of this question. I am also using the default code generator (not poco or self tracking). I am expecting that anytime I query the context for the framework to only make a round trip if I have not already fetched those objects. I do get this behaviour if I turn off lazy loading. Currently in my application I am breifly turning on lazy loading and then turning it back off so I can get the desired behaviour. That pretty much sucks, so please help. Here is a good code example that can demonstrate my problem. Public Sub ManyRoundTrips() context.ContextOptions.LazyLoadingEnabled = True Dim employees As List(Of Employee) = context.Employees.Execute(System.Data.Objects.MergeOption.AppendOnly).ToList() 'makes unnessesary round trip to the database, I just loaded the employees' MessageBox.Show(context.Employees.Where(Function(x) x.EmployeeID < 10).ToList().Count) context.Orders.Execute(System.Data.Objects.MergeOption.AppendOnly) For Each emp As Employee In employees 'makes unnessesary trip to database every time despite orders being pre loaded.' Dim i As Integer = emp.Orders.Count Next End Sub Public Sub OneRoundTrip() context.ContextOptions.LazyLoadingEnabled = True Dim employees As List(Of Employee) = context.Employees.Include("Orders").Execute(System.Data.Objects.MergeOption.AppendOnly).ToList() MessageBox.Show(employees.Where(Function(x) x.EmployeeID < 10).ToList().Count) For Each emp As Employee In employees Dim i As Integer = emp.Orders.Count Next End Sub Why is the first block of code making unnessesary round trips?

  • LINQ to SQL and DataPager

    - by Jonathan S.
    I'm using LINQ to SQL to search a fairly large database and am unsure of the best approach to perform paging with a DataPager. I am aware of the Skip() and Take() methods and have those working properly. However, I'm unable to use the count of the results for the datapager, as they will always be the page size as determined in the Take() method. For example: var result = (from c in db.Customers where c.FirstName == "JimBob" select c).Skip(0).Take(10); This query will always return 10 or fewer results, even if there are 1000 JimBobs. As a result, the DataPager will always think there's a single page, and users aren't able to navigate across the entire result set. I've seen one online article where the author just wrote another query to get the total count and called that. Something like: int resultCount = (from c in db.Customers where c.FirstName == "JimBob" select c).Count(); and used that value for the DataPager. But I'd really rather not have to copy and paste every query into a separate call where I want to page the results for obvious reasons. Is there an easier way to do this that can be reused across multiple queries? Thanks.

  • Capturing time intervals when somebody was online? How would you impement this feature?

    - by Kirzilla
    Hello, Our aim is to build timelines saying about periods of time when user was online. (It really doesn't matter what user we are talking about and where he was online) To get information about onliners we can call API method, someservice.com/api/?call=whoIsOnline whoIsOnline method will give us a list of users currently online. But there is no API method to get information about who IS NOT online. So, we should build our timelines using information we got from whoIsOnline. Of course there will be a measurement error (we can't track information in realtime). Let's suppose that we will call whoIsOnline method every 2 minutes (yes, we will run our script by cron every 2 minutes). For example, calling whoIsOnline at 08:00 will return Peter_id Michal_id Andy_id calling whoIsOnline at 08:02 will return Michael_id Andy_id George_id As you can see, Peter has gone offline, but we have new onliner - George. Available instruments are Db(MySQL) / text files / key-value storage (Redis/memcache); feel free to choose any of them (or even all of them). So, we have to get information like this George_id was online... 12 May: 08:02-08:30, 12:40-12:46, 20:14-22:36 11 May: 09:10-12:30, 21:45-23:00 10 May: was not online And now question... How would you store information to implement such timelines? How would you query/calculate information about periods of time when user was online? Additional information.. You cannot update information about offline users, only users who are "currently" online. Solution should be flexible: timeline information could be represented relating to any timezone. We should keep information only for last 7 days. Every user seen online is automatically getting his own identifier in our database. Uff.. it was really hard for me to write it because my English is pretty bad, but I hope my question will be clear for you. Thank you.
