  • WPF: How to data bind an object to an element and apply a data template through code?

    - by Boris
    I have created a class LeagueMatch. public class LeagueMatch { public string Home { get { return home; } set { home = value; } } public string Visitor { get { return visitor; } set { visitor = value; } } private string home; private string visitor; public LeagueMatch() { } } Next, I have defined a datatemplate resource for LeagueMatch objects in XAML: <DataTemplate x:Key="MatchTemplate" DataType="{x:Type entities:LeagueMatch}"> <Grid Name="MatchGrid" Width="140" Height="50" Margin="5"> <Grid.RowDefinitions> <RowDefinition Height="*" /> <RowDefinition Height="*" /> <RowDefinition Height="*" /> </Grid.RowDefinitions> <TextBlock Grid.Row="0" Text="{Binding Home}" /> <TextBlock Grid.Row="1" Text="- vs -" /> <TextBlock Grid.Row="2" Text="{Binding Visitor}" /> </Grid> </DataTemplate> In the XAML code-behind, I want to create a ContentPresenter object and to set it's data binding to a previously initialized LeagueMatch object and apply the defined data template. How is that supposed to be done? Thanks.

  • Uncatchable AccesViolationException

    - by Roy
    Hi all, I'm getting close to desperate.. I am developing a field service application for Windows Mobile 6.1 using C# and quite some p/Invoking. (I think I'm referencing about 50 native functions) On normal circumstances this goes without any problem, but when i start stressing the GC i'm getting a nasty 0xC0000005 error witch seems uncatchable. In my test i'm rapidly closing and opening a dialog form (the form did make use of native functions, but for testing i commented these out) and after a while the Windows Mobile error reporter comes around to tell me that there was an fatal error in my application. My code uses a try-catch around the Application.Run(masterForm); and hooks into the CurrentDomain.UnhandledException event, but the application still crashes. Even when i attach the debugger, visual studio just tells me "The remote connection to the device has been lost" when the exception occurs.. Since I didn't succeed to catch the exception in the managed environment, I tried to make sense out of the Error Reporter log file. But this doesn't make any sense, the only consistent this about the error is the application where it occurs in. The thread where the application occurs in is unknown to me, the module where the error occurs differs from time to time (I've seen my application.exe, WS2.dll, netcfagl3_5.dll and mscoree3_5.dll), even the error code is not always the same. (most of the time it's 0xC0000005, but i've also seen an 0X80000002 error, which is a warning accounting the first byte?) I tried debugging through bugtrap, but strangely enough this crashes with the same error code (0xC0000005). I tried to open the kdmp file with visual studio, but i can't seem to make any sense out of this because it only shows me disassembler code when i step into the error (unless i have the right .pbb files, which i don't). Same goes for WinDbg. To make a long story short: I frankly don't have a single clue where to look for this error, and I'm hoping some bright soul on stackoverflow does. I'm happy to provide some code but at this moment I don't know which piece to provide.. Any help is greatly appreciated!

  • Per-pixel per-component alpha blending in Windows

    - by Crend King
    I have a 24-bit bitmaps with R, G, B color channels and a 24-bit bitmap with R, G, B alpha channels. I want to alpha blend the first bitmap to a HDC in GDI or RenderTarget in Direct2D with the alpha channels respectively. For example, suppose for one pixel, the bitmap color is (192, 192, 192), the HDC color is (0, 255, 255) and the alpha channels are (30, 40, 50). The final HDC color should be (22, 245, 242). I know I can BitBlt the HDC to a memory HDC first, do alpha blending by manually calculating the color of each pixel and finally BitBlt back. I just want to avoid the additional blitting and leave APIs do their job (faster since they are in kernel space). The first idea comes to my mind is to split the source bitmap into 3 red-only, green-only and blue-only 8-bit bitmaps, do normal alpha blending, then composite the 3 output bitmaps into the HDC. But I don't find a way to do the splitting and composition natively in Windows (would Direct2D layer help?). Also, the splitting and compositing may require many additional copying. The performance overhead would be too high. Or maybe do the alpha blending in 3 passes. Each pass apply the blending for one channel, while maintaining the other 2 unchanged. Thanks for any comment. EDIT: I found this question, and the answer should be good reference to this problem. However, besides AC_SRC_OVER, there is no other blending operation supported. Why don't Microsoft improve their API?

  • Unable to load images into each MC?

  • Displaying indexed png- files out of NSArray on the iphone screen

    - by Thomas Hülsmann
    Hi, i like to create an artwork counter- display on an iphone, diplaying 0 to 9. The 10 digits are 10 png- files with the numbers 0 to 9 as their artwork content. The 10 png- files are implemented by using NSArray. Following you'll find the implementation- code: zahlenArray = [NSArray arrayWithObjects: [UIImage imageNamed:@"ziffer-0.png"], [UIImage imageNamed:@"ziffer-1.png"], [UIImage imageNamed:@"ziffer-2.png"], [UIImage imageNamed:@"ziffer-3.png"], [UIImage imageNamed:@"ziffer-4.png"], [UIImage imageNamed:@"ziffer-5.png"], [UIImage imageNamed:@"ziffer-6.png"], [UIImage imageNamed:@"ziffer-7.png"], [UIImage imageNamed:@"ziffer-8.png"], [UIImage imageNamed:@"ziffer-9.png"], nil]; As an index for the 10 digitis I use an integer variable, initializing with 0: int counter = 0; Furthermore I declare an UIImageview programmaticaly: UIImageView *zahlenEinsBisNeun; The implementation code for the UIImageview is: zahlenEinsBisNeun = [UIImage alloc] initWithFrame:CGRectMake(240, 50, 200, 200)]; ???????????????????????????????????????? [self.view addSubview:zahlenEinsBisNeun]; [zahlenEinsBisNeun release]; There, where you see the questionmarks, I don't know how to write the code, to retrieve my content artworks 0 to 9 from NSArray with the index "counter" and make it visible on my iphone screen by using .... addSubview:zahlenEinsBisNeun ... Can anybody help??? My thanks for your support in advance Thomas Hülsmann

  • Using open2300 with Ubuntu

    - by Gawain
    Hello, I am currently running Ubuntu 8.10 and have been trying to use Open2300 to read data from a Lacrosse WS-2310 weather station and report it to the WUnderground server. The program compiles fine but when I try to run it, it does one of two things: usually it pauses for about 4 minutes, then prints "could not reset" to the screen. But sometimes it just hangs forever. It seems like my computer is unable to communicate with the weather station. I have set the serial port as /dev/ttyS0 in the open2300.conf file and i have also tried /dev/ttyS1, /dev/ttyS2, etc with the same result. As far as I can tell, there are no other settings regarding how Open2300 communicates with the device. Is my serial port locked somehow? It could be something as simple as an incorrect configuration for my serial port or something, but I would have no idea how to check that or change the configuration. Any help would be greatly appreciated. thanks, Gawain EDIT: I tried some tests that i found online and everything seems to be working with my serial port... gawain@gawain:~$ ls -l /dev/ttyS* crw-rw---- 1 root dialout 4, 64 2009-07-09 10:01 /dev/ttyS0 crw-rw---- 1 root dialout 4, 65 2009-07-09 08:56 /dev/ttyS1 crw-rw---- 1 root dialout 4, 66 2009-07-09 08:56 /dev/ttyS2 crw-rw---- 1 root dialout 4, 67 2009-07-09 08:56 /dev/ttyS3 gawain@gawain:~$ setserial -a /dev/ttyS0 /dev/ttyS0, Line 0, UART: 16550A, Port: 0x03f8, IRQ: 4 Baud_base: 115200, close_delay: 50, divisor: 0 closing_wait: 3000 Flags: spd_normal skip_test gawain@gawain:~$ setserial -g /dev/ttyS* /dev/ttyS0, UART: 16550A, Port: 0x03f8, IRQ: 4 /dev/ttyS1, UART: 8250, Port: 0xd028, IRQ: 18 /dev/ttyS2, UART: 8250, Port: 0xd040, IRQ: 18 /dev/ttyS3, UART: 8250, Port: 0xd050, IRQ: 18 gawain@gawain:~$ echo 12345 > /dev/ttyS0 gawain@gawain:~$ dmesg | tail -3 [ 144.424259] ppdev0: unregistered pardevice [ 145.692199] ppdev0: registered pardevice [ 145.740052] ppdev0: unregistered pardevice I also tried changing the serial port name to /dev/ttys0 (with a lowercase S) and in that case it gave me a different error, "Unable to open serial device." This suggests to me that it is able to open /dev/ttyS0 but something else is preventing it from reading the weather station. Any ideas? thanks.

  • Python: How to execute a SQL file or command

    - by Mestika
    Hi, I have this Python script: import sys import getopt import timeit import random import os import re import ibm_db import time from string import maketrans runs=5 queries=50 file = open("results.txt", "a") for r in range(5): print "Run %s\n" % r os.system("python reads.py -r1 -pquery1.sql -q50 -sespec") file.write('END QUERY READ 01') file.close() os.system("python query_read_02.py") Everything here is working, it is creating the results.txt file, it run the os.system("python reads.py...") file and that file is doing everything it's suppose to, but the problem comes when go and run the query_read_02.py file. In this file, it should execute a SQL command or a SQL file on my database, so I can create an index and see what the performance of that input is, but how do i do it? I create the connection to the database in the reads.py file, but it's hard to create the queries in there because I doesn't keep track of which file it has reached, it just execute commands from what the parameters are. I hope I've explained myself clear enough, otherwise please let me know. I just want to execute a SQL command or file which each query_read_0x.py file. Sincerely Mestika

  • emacs frustration with web development

    - by Tony Cruise
    I really liked flexibility of emacs but it is really annoying to make it work. I want to use it for web development html, css, javascript, php. I first tried emacs-starter-kit . It didn't included nXhtml. Also C-g key binding does not work (they call it starter kit but basic key command does not work). I think it is mapped for git control. That's a frustration for a beginner. Then I replaced emacs-starter-kit with nXhtml. At least C-g is working. But code completion sucks, M-tab does not work. I tried code completion from nXhtml menu with no success. Also NXhtml mode did'nt colorized my file if css is mixed with html. Isn't it recommended for mixed html, css,php files. So why it doesnt work?. Why Emacs folks do not aware of convention over configuration? Dam! ship it something works! Please help me before I am getting crazy. I use Ubuntu 10.04 and emacs-snaphot-gtk 23.1.50-1. Please guide step by step with your working dotfile url. Even I accept I am a dummy it really annoying and frustrating to use emacs.

  • Python: Seeing all files in Hex.

    - by Recursion
    I am writing a python script which looks at common computer files and examines them for similar bytes, words, double word's. Though I need/want to see the files in Hex, ande cannot really seem to get python to open a simple file in python. I have tried codecs.open with hex as the encoding, but when I operate on the file descriptor it always spits back File "main.py", line 41, in <module> main() File "main.py", line 38, in main process_file(sys.argv[1]) File "main.py", line 27, in process_file seeker(line.rstrip("\n")) File "main.py", line 15, in seeker for unit in f.read(2): File "/usr/lib/python2.6/codecs.py", line 666, in read return self.reader.read(size) File "/usr/lib/python2.6/codecs.py", line 472, in read newchars, decodedbytes = self.decode(data, self.errors) File "/usr/lib/python2.6/encodings/hex_codec.py", line 50, in decode return hex_decode(input,errors) File "/usr/lib/python2.6/encodings/hex_codec.py", line 42, in hex_decode output = binascii.a2b_hex(input) TypeError: Non-hexadecimal digit found def seeker(_file): f = codecs.open(_file, "rb", "hex") for LINE in f.read(): print LINE f.close() I really just want to see files, and operate on them as if it was in a hex editor like xxd. Also is it possible to read a file in increments of maybe a word at a time. No this is not homework.

  • Figuring out the performance limitation of an ADC on a PIC microcontroller

    - by AKE
    I'm spec-ing the suitability of a microcontroller like PIC for an analog-to-digital application. This would be preferable to using external A/D chips. To do that, I've had to run through some computations, pulling the relevant parameters from the datasheets. I'm not sure I've got it right -- would appreciate a check! Here's the simplest example: PIC10F220 is the simplest possible PIC with an ADC. Runs at clock speed of 8MHz. Has an instruction cycle of 0.5us (4 clock steps per instruction) So: Taking Tacq = 6.06 us (acquisition time for ADC, assume chip temp. = 50*C) [datasheet p34] Taking Fosc = 8MHz (? clock speed) Taking divisor = 4 (4 clock steps per CPU instruction) This gives TAD = 0.5us (TAD = 1/(Fosc/divisor) ) Conversion time is 13*TAD [datasheet p31] This gives conversion time 6.5us ADC duration is then 12.56 us [? Tacq + 13*TAD] Assuming at least 2 instructions for load/store: This is another 1 us [0.5 us per instruction] Which would give max sampling rate of 73.7 ksps (1/13.56) Supposing 8 more instructions for real-time processing: This is another 4 us Thus, total ADC/handling time = 17.56us (12.56us + 1us + 4us) So expected upper sampling rate is 56.9 ksps. Nyquist frequency for this sampling rate is therefore 28 kHz. If this is right, it suggests the (theoretical) performance suitability of this chip's A/D is for signals that are bandlimited to 28 kHz. Is this a correct interpretation of the information given in the data sheet? Any pointers would be much appreciated! AKE

  • WPF toolbar disappearing on resize

    - by user1122909
    On my main form I have a toolbar with a number of buttons. Once the parent form is resized down by dragging it so that the entire toolbar with all its buttons no longer fits in the width of the window, the whole toolbar disappears. Is there a way I can make it so that as you resize it, when you get to the width of the toolbar the inner controls of the form stop resizing and stay displayed, just cut off where the window has resized to? Code is <Grid > <Grid.RowDefinitions> <RowDefinition Height="Auto" /> <RowDefinition Height="Auto" /> <RowDefinition Height="*" /> <RowDefinition Height="Auto" /> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="*" /> </Grid.ColumnDefinitions> <ToolBar Grid.Row="1" Height="50" Name="tbMainToolbar" VerticalAlignment="Top" MinWidth="900" > <ToolBar.Background> <LinearGradientBrush StartPoint="0.5,0" EndPoint="0.5,1"> <GradientStop Color="White" Offset="0.0" /> <GradientStop Color="#DCEBFF" Offset="0.25" /> <GradientStop Color="#99CCFF" Offset="0.75" /> <GradientStop Color="#99CCFF" Offset="1.0" /> </LinearGradientBrush> </ToolBar.Background> <DockPanel LastChildFill="True"> <Button Name="btnApproved" DockPanel.Dock="Left" Click="btnToolbar_Click" CommandParameter="APPROVED" Style="{StaticResource ToolbarButtonDisplay}" HelperClasses:ButtonProperties.Image="..\..\Resources\Images\APPROVEU.GIF" Content="Approve"> </Button> ... and so forth for about 20 buttons

  • Extend base type and automatically update audit information on Entity

    - by Nix
    I have an entity model that has audit information on every table (50+ tables) CreateDate CreateUser UpdateDate UpdateUser Currently we are programatically updating audit information. Ex: if(changed){ entity.UpdatedOn = DateTime.Now; entity.UpdatedBy = Environment.UserName; context.SaveChanges(); } But I am looking for a more automated solution. During save changes, if an entity is created/updated I would like to automatically update these fields before sending them to the database for storage. Any suggestion on how i could do this? I would prefer to not do any reflection, so using a text template is not out of the question. A solution has been proposed to override SaveChanges and do it there, but in order to achieve this i would either have to use reflection (in which I don't want to do ) or derive a base class. Assuming i go down this route how would I achieve this? For example EXAMPLE_DB_TABLE CODE NAME --Audit Tables CREATE_DATE CREATE_USER UPDATE_DATE UPDATE_USER And if i create a base class public abstract class IUpdatable{ public virtual DateTime CreateDate {set;} public virtual string CreateUser { set;} public virtual DateTime UpdateDate { set;} public virtual string UpdateUser { set;} } The end goal is to be able to do something like... public overrride void SaveChanges(){ //Go through state manager and update audit infromation //FOREACH changed entity in state manager if(entity is IUpdatable){ //If state is created... update create audit. //if state is updated... update update audit } } But I am not sure how I go about generating the code that would extend the interface.

  • How can I control the action of onbeforeunload in IE?

    Hi all I've got a problem about onbeforeunload recently that I need to pop up a voting page if the user try closes their IE browser.And I did it by using <body onbeforeunload="makevote()"> And the main structure of makevote() in javascript as follows: function makevote() { comet.distruct(); if(csid != null && isvote == null) { window.event.returnValue = false window.event.returnValue='press “cancel” to vote please!' showComDiv(popvote,"popiframe",400,120,'your vote here','dovote()'); } } For last three months this voting function performed so ugly that I got only less than 8,000 votes from more than 4,50,000 vistors.I think the problem is, when the users try to close their browsers,the onbeforeunload property pops up a comfirm box which covered my voting box while most users click the OK button,which means close comfirming is done,as a habit.So my question is how can I control the comfirming box made by onbeforeunload myself? So far I can only define the message it shows.For example if I click the "OK" ,I'll go to the voting box instead of closing my IE.And if there's any other better way to do this?Help would be greatly appreciated! Regards

  • GWT forced height HTMLPanel

    - by Nils
    Hello, I'm developing a GWT project, and I encountered a problematic cross-browsering problem. When using firefox, there are problems with the display of all the pages. I found the reason why : In UIBinder, each of my pages are wrapped by a "g:HTMLPanel" : at start and at the end of the xml file, to wrap the content of all the pages When doing this, the generated code of the panel goes like this : div style="width: 100%; height: 100%; .... The problem is that "height : 100%". If I remove it with firebug, the display is perfect. So my goal is to programatically remove that generated 100% height.. But no way to do it ! I tried everything : setHeight, setSize, working on the Element itself with getElement().methods()... I tried to do things like style.clear(), everything that could have a chance to work.. But in the generated code that "height: 100%" will ALWAYS be there. If I set it's height to "50%" or "50px" it has no effect at all. I even tried to give it an ID, then with pure javascript to change it's style, but no solution either.. Note : I'm sure that I'm working on the right element : adding a styleName, for example, works well. Any idea ? Your help would be really appreciated, I have no clue of how to remove this bit of generated code, and I've been looking for hours already :(:(:(:( Best regards, Nils

  • What are some funny loading statements to keep users amused?

    - by Oli
    Nobody likes waiting but unfortunately in the Ajax application I'm working on at the moment, there is one fair-sized pause (1-2 seconds a go) that users have to undergo each and every time they want to load up a chunk of data. I've tried to make the load as interactive as possible. There's an animated GIF alongside a very plain, very dull "Loading..." message. So I thought it might be quite fun to come up with a batch of 50-or-so funny-looking messages and pick from them randomly so the user never knows what they're going to see. The time they would have spent growing impatient is fruitfully used. Here's what I've come up with so far, just to give you an idea. var randomLoadingMessage = function() { var lines = new Array( "Locating the required gigapixels to render...", "Spinning up the hamster...", "Shovelling coal into the server...", "Programming the flux capacitor" ); return lines[Math.round(Math.random()*(lines.length-1))]; } (Yes -- I know some of those are pretty lame -- That's why I'm here :) The funniest I see today will get the prestigious "Accepted Answer" award. Others get votes for participation. Enjoy!!

  • Reading HTML table data / html tag

    - by user348038
    I have some 50 pages of html which have around 100-plus rows of data in each, with all sort of CSS style, I want to read the html file and just get the data, like Name, Age, Class, Teacher. and store it in Database, but I am not able to read the html tags e.g space i kept to display it here <table class="table_100"> <tr> <td class="col_1"> <span class="txt_student">Gauri Singh</span><br> <span class="txt_bold">13</span><br> <span class="txt_bold">VIII</span><br> </td> <td class="col_2"> <span class="txt_teacher">Praveen M</span><br> <span class="txt_bold">3494</span><br> <span class="txt_bold">3Star</span><br> </td> <td class="col_3"> </td> </tr> </table>

  • problems with infinite loop

    - by Tom
    function addAds($n) { for ($i=0;$i<=$n;$i++) { while($row=mysql_fetch_array(mysql_query("SELECT * FROM users"))) { $aut[]=$row['name']; } $author=$aut[rand(0,mysql_num_rows(mysql_query("SELECT * FROM users")))]; $name="pavadinimas".rand(0,3600); $rnd=rand(0,1); if($rnd==0) { $type="siulo"; } else { $type="iesko"; } $text="tekstas".md5("tekstas".rand(0,8000)); $time=time()-rand(3600,86400); $catid=rand(1,9); switch ($catid) { case 1: $subid=rand(1,8); break; case 2: $subid=rand(9,16); break; case 3: $subid=rand(17,24); break; case 4: $subid=rand(25,32); break; case 5: $subid=rand(33,41); break; case 6: $subid=rand(42,49); break; case 7: $subid=rand(50,56); break; case 8: $subid=rand(57,64); break; case 9: $subid=rand(65,70); break; } mysql_query("INSERT INTO advert(author,name,type,text,time,catid,subid) VALUES('$author','$name','$type','$text','$time','$catid','$subid')") or die(mysql_error()); } echo "$n adverts successfully added."; } The problem with this function, is that it never loads. As I noticed, my while loop causes it. If i comment it, everything is ok. It has to get random user from my db and set it to variable $author.

  • Out of Core Implementation of a Quadtree

    - by Nima
    Hi, I am trying to build a Quadtree data structure(or let's just say a tree) on the secondary memory(Hard Disk). I have a C++ program to do so and I use fopen to create the files. Also, I am using tesseral coding to store each cell in a file named with its corresponding code to store it on the disk in one directory. The problem is that after creating about 1,100 files, fopen just returns NULL and stops creating new files. I can create further files manually in that directory, but using C++ it can not create any further files. I know about max limit of inode on ext3 filesystem which is (from Wikipedia) 32,000 but mine is way less than that, also note that I can create files manually on the disk; just not through fopen. Also, I really appreciate any idea regarding the best way to store a very dynamic quadtree on disk(I need the nodes to be in separate files and the quadtree might have a depth of 50). Using nested directories is one idea, but I think it will slow down the performance because of following the links on the filesystem to access the file. Thanks, Nima
