• Unicenter Software Delivery 4 not able to connect to MS SQL 2000 Database after W2003 SP2 upgrade

  - by grub

  Hello Everyone Yesterday I installed the Windows Server 2003 Service Pack 2 on a Windows Server 2003 which has Unicenter Software Delivery 4 installed. Prior to the installation I disabled every CA service on the server (Brightstor, SDO , RCO, TNG) and the MS SQL 2000 service. After the installation of the SP2 I enabled the services again but the Unicenter Service is not able to connect to the MS SQL 2000 Database anymore. The database itself is up and running and I can connect to it with the Enterprise Manager. A dbcc checkdb doesnt return any errors on the Unicenter database. The Unicenter service throws the following error messages during startup: IM[1] 27/05 10:38:31,272 Installation Manager in init phase IM[1] 27/05 10:38:31,694 Process IM(L) - [004152] failed to open database SDDATA. dbopen() call failed.

The configuration is the same and the same driver and software versions are used. Do you have any idea what causes the connection issue? Should I deinstall the unicenter service and make a fresh installation on the server or should I remove the Windows Server 2003 SP2? I don't want to remove the SP2 because it's a requirement for WSUS3 SP2 and I really don't want to know how many possible exploits are possible in such an old system ;-) Thank you very much and have a nice day.

• Can't get simple Apache VHost up and running

  - by TK Kocheran

  Unfortunately, I can't seem to get a simple Apache VHost online. I used to simply have one VHost which bound to all: <VirtualHost *:80>, but this isn't appropriate for security anymore. I need to have one VHost for localhost requests (ie my dev server) and one for incoming requests via my domain name. Here's my new VHost: NameVirtualHost domain1.com <VirtualHost domain1.com:80> DocumentRoot /var/www ServerName domain1.com </VirtualHost> <VirtualHost domain2.com:80> DocumentRoot /var/www ServerName domain2.com </VirtualHost> After I restart my server, I see the following errors in my log: [Wed Feb 16 11:26:36 2011] [error] [client ####.###.###.###] File does not exist: /htdocs [Wed Feb 16 11:26:36 2011] [error] [client ####.###.###.###] File does not exist: /htdocs What am I doing wrong? EDIT As per the answer give below, I have modified my configuration. Here are my configuration files: /etc/apache2/ports.conf: Listen 80 <IfModule mod_ssl.c> # If you add NameVirtualHost *:443 here, you will also have to change # the VirtualHost statement in /etc/apache2/sites-available/default-ssl # to <VirtualHost *:443> # Server Name Indication for SSL named virtual hosts is currently not # supported by MSIE on Windows XP.

Directives that define the parameters of the 'main' or 'default' server, # which responds to requests that aren't handled by a virtual host. # These directives also provide default values for the settings # of all virtual hosts. # 3. Settings for virtual hosts, which allow Web requests to be sent to # different IP addresses or hostnames and have them handled by the # same Apache server process. # # Configuration and logfile names: If the filenames you specify for many # of the server's control files begin with "/" (or "drive:/" for Win32), the # server will use that explicit path. If the filenames do *not* begin # with "/", the value of ServerRoot is prepended -- so "/var/log/apache2/foo.log" # with ServerRoot set to "" will be interpreted by the # server as "//var/log/apache2/foo.log". # ### Section 1: Global Environment # # The directives in this section affect the overall operation of Apache, # such as the number of concurrent requests it can handle or where it # can find its configuration files. # # # ServerRoot: The top of the directory tree under which the server's # configuration, error, and log files are kept. # # NOTE!

• Set up linux box for secure local hosting a-z

  - by microchasm

  I am in the process of reinstalling the OS on a machine that will be used to host a couple of apps for our business. The apps will be local only; access from external clients will be via vpn only. The prior setup used a hosting control panel (Plesk) for most of the admin, and I was looking at using another similar piece of software for the reinstall - but I figured I should finally learn how it all works. I can do most of the things the software would do for me, but am unclear on the symbiosis of it all. This is all an attempt to further distance myself from the land of Configuration Programmer/Programmer, if at all possible. I can't find a full walkthrough anywhere for what I'm looking for, so I thought I'd put up this question, and if people can help me on the way I will edit this with the answers, and document my progress/pitfalls. Hopefully someday this will help someone down the line. The details: CentOS 5.5 x86_64 httpd: Apache/2.2.3 mysql: 5.0.77 (to be upgraded) php: 5.1 (to be upgraded) The requirements: SECURITY!! Secure file transfer Secure client access (SSL Certs and CA) Secure data storage Virtualhosts/multiple subdomains Local email would be nice, but not critical The Steps: Download latest CentOS DVD-iso (torrent worked great for me). Install CentOS: While going through the install, I checked the Server Components option thinking I was going to be using another Plesk-like admin. In hindsight, considering I've decided to try to go my own way, this probably wasn't the best idea. Basic config: Setup users, networking/ip address etc. Yum update/upgrade. Upgrade PHP/MySQL: To upgrade PHP and MySQL to the latest versions, I had to look to another repo outside CentOS. IUS looks great and I'm happy I found it! Add IUS repository to our package manager cd /tmp wget http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/epel-release-1-1.ius.el5.noarch.rpm rpm -Uvh epel-release-1-1.ius.el5.noarch.rpm wget http://dl.iuscommunity.org/pub/ius/stable/Redhat/5/x86_64/ius-release-1-4.ius.el5.noarch.rpm rpm -Uvh ius-release-1-4.ius.el5.noarch.rpm yum list | grep -w \.ius\. # list all the packages in the IUS repository; use this to find PHP/MySQL version and libraries you want to install Remove old version of PHP and install newer version from IUS rpm -qa | grep php # to list all of the installed php packages we want to remove yum shell # open an interactive yum shell remove php-common php-mysql php-cli #remove installed PHP components install php53 php53-mysql php53-cli php53-common #add packages you want transaction solve #important!! checks for dependencies transaction run #important!! does the actual installation of packages.

In this users' home directory, I created a folder called 'https'. This is where the documents for this site will live, so I need to add a virtualhost that will point to it. I will use the above virtual interface for this site (herein called dev.site.local). vi /etc/http/conf/httpd.conf Add the following to the end of httpd.conf: <VirtualHost 192.168.1.3:80> ServerAdmin [email protected] DocumentRoot /home/dev/https ServerName dev.site.local ErrorLog /home/dev/logs/error_log TransferLog /home/dev/logs/access_log </VirtualHost> I put a dummy index.html file in the https directory just to check everything out. I tried browsing to it, and was met with permission denied errors. The logs only gave an obscure reference to what was going on: [Mon May 17 14:57:11 2010] [error] [client 192.168.1.100] (13)Permission denied: access to /index.html denied I tried chmod 777 et. al., but to no avail. Turns out, I needed to chmod+x the https directory and its' parent directories. chmod +x /home chmod +x /home/dev chmod +x /home/dev/https This solved that problem. DNS I'm handling DNS via our local Windows Server 2003 box. However, the CentOS documentation for BIND can be found here: http://www.centos.org/docs/5/html/Deployment_Guide-en-US/ch-bind.html SSL To get SSL working, I changed the following in httpd.conf: NameVirtualHost 192.168.1.3:443 #make sure this line is in httpd.conf <VirtualHost 192.168.1.3:443> #change port to 443 ServerAdmin [email protected] DocumentRoot /home/dev/https ServerName dev.site.local ErrorLog /home/dev/logs/error_log TransferLog /home/dev/logs/access_log </VirtualHost> Unfortunately, I keep getting (Error code: ssl_error_rx_record_too_long) errors when trying to access a page with SSL. As JamesHannah gracefully pointed out below, I had not set up the locations of the certs in httpd.conf, and thusly was getting the page thrown at the broswer as the cert making the browser balk. So first, I needed to set up a CA and make certificate files. I found a great (if old) walkthrough on the process here: http://www.debian-administration.org/articles/284. Here are the relevant steps I took from that article: mkdir /home/CA cd /home/CA/ mkdir newcerts private echo '01' > serial touch index.txt #this and the above command are for the database that will keep track of certs Create an openssl.cnf file in the /home/CA/ dir and edit it per the walkthrough linked above. (For reference, my finished openssl.cnf file looked like this: http://pastebin.com/raw.php?i=hnZDij4T) openssl req -new -x509 -extensions v3_ca -keyout private/cakey.pem -out cacert.pem -days 3650 -config ./openssl.cnf #this creates the cacert.pem which gets distributed and imported to the browser(s) Modified openssl.cnf again per walkthrough instructions. openssl req -new -nodes -out dev.req.pem -config ./openssl.cnf #generates certificate request, and key.pem which I renamed dev.key.pem. Modified openssl.cnf again per walkthrough instructions. openssl ca -out dev.cert.pem -config ./openssl.cnf -infiles dev.req.pem #create and sign certificate. cp dev.cert.pem /home/dev/certs/cert.pem cp dev.key.pem /home/certs/key.pem I updated httpd.conf to reflect the certs and turn SSLEngine on: NameVirtualHost 192.168.1.3:443 <VirtualHost 192.168.1.3:443> ServerAdmin [email protected] DocumentRoot /home/dev/https SSLEngine on SSLCertificateFile /home/dev/certs/cert.pem SSLCertificateKeyFile /home/dev/certs/key.pem ServerName dev.site.local ErrorLog /home/dev/logs/error_log TransferLog /home/dev/logs/access_log </VirtualHost> Put the CA cert.pem in a web-accessible place, and downloaded/imported it into my browser. Now I can visit https://dev.site.local with no errors or warnings. And this is where I'm at. I will keep editing this as I make progress. Any tips on how to configure SSL email would be appreciated.

• Benchmark Linq2SQL, Subsonic2, Subsonic3 - Any other ideas to make them faster ?

  - by Aristos

  I am working with Subsonic 2 more than 3 years now... After Linq appears and then Subsonic 3, I start thinking about moving to the new Linq futures that are connected to sql. I must say that I start move and port my subsonic 2 with SubSonic 3, and very soon I discover that the speed was so slow thats I didn't believe it - and starts all that tests. Then I test Linq2Sql and see also a delay - compare it with Subsonic 2. My question here is, especial for the linq2sql, and the up-coming dotnet version 4, what else can I do to speed it up ? What else on linq2sql settings, or classes, not on this code that I have used for my messures I place here the project that I make the tests, also the screen shots of the results. How I make the tests - and the accurate of my measures. I use only for my question Google chrome, because its difficult for me to show here a lot of other measures that I have done with more complex programs. This is the most simple one, I just measure the Data Read. How can I prove that. I make a simple Thread.Sleep(10 seconds) and see if I see that 10 seconds on Google Chrome Measure, and yes I see it. here are more test with this Sleep thead to see whats actually Chrome gives. 10 seconds delay 100 ms delay Zero delay There is only a small 15ms thats get on messure, is so small compare it with the rest of my tests that I do not care about. So what I measure I measure just the data read via each method - did not count the data or database delay, or any disk read or anything like that. Later on the image with the result I show that no disk activity exist on the measures See this image to see what really I measure and if this is correct Why I chose this kind of test Its simple, it's real, and it's near my real problem that I found the delay of subsonic 3 in real program with real data. Now lets tests the dals Start by see this image I have 4-5 calls on every method, the one after the other. The results are. For a loop of 100 times, ask for 5 Rows, one not exist, approximatively.. Simple adonet:81ms SubSonic 2 :210ms linq2sql :1.70sec linq2sql using CompiledQuery.Compile :239ms Subsonic 3 :15.00sec (wow - extreme slow) The project http://www.planethost.gr/DalSpeedTests.rar Can any one confirm this benchmark, or make any optimizations to help me out ? Other tests Some one publish here this link http://ormbattle.net/ (and then remove it - don not know why) In this page you can find a really useful advanced tests for all, except subsonic 2 and subsonic 3 that I have here ! Optimizing What I really ask here is if some one can now any trick how to optimize the DALs, not by changing the test code, but by changing the code and the settings on each dal. For example... Optimizing Linq2SQL I start search how to optimize Linq2sql and found this article, and maybe more exist. Finally I make the tricks from that page to run, and optimize the code using them all. The speed was near 1.50sec from 1.70.... big improvement, but still slow. Then I found a different way - same idea article, and wow ! the speed is blow up. Using this trick with CompiledQuery.Compile, the time from 1.5sec is now 239ms. Here is the code for the precompiled... Func<DataClassesDataContext, int, IQueryable<Product>> compiledQuery = CompiledQuery.Compile((DataClassesDataContext meta, int IdToFind) => (from myData in meta.Products where myData.ProductID.Equals(IdToFind) select myData)); StringBuilder Test = new StringBuilder(); int[] MiaSeira = { 5, 6, 10, 100, 7 }; using (DataClassesDataContext context = new DataClassesDataContext()) { context.ObjectTrackingEnabled = false; for (int i = 0; i < 100; i++) { foreach (int EnaID in MiaSeira) { var oFindThat2P = compiledQuery(context, EnaID); foreach (Product One in oFindThat2P) { Test.Append("<br />"); Test.Append(One.ProductName); } } } } Optimizing SubSonic 3 and problems I make many performance profiling, and start change the one after the other and the speed is better but still too slow. I post them on subsonic group but they ignore the problem, they say that everything is fast... Here is some capture of my profiling and delay points inside subsonic source code I have end up that subsonic3 make more call on the structure of the database rather than on data itself. Needs to reconsider the hole way of asking for data, and follow the subsonic2 idea if this is possible. Try to make precompile to subsonic 3 like I did in linq2Sql but fail for the moment... Optimizing SubSonic 2 After I discover that subsonic 3 is extreme slow, I start my checks on subsonic 2 - that I have never done before believing that is fast. (and it is) So its come up with some points that can be faster. For example there are many loops like this ones that actually is slow because of string manipulation and compares inside the loop. I must say to you that this code called million of times ! on a period of few minutes ! of data asking from the program. On small amount of tables and small fields maybe this is not a big think for some people, but on large amount of tables, the delay is even more. So I decide and optimize the subsonic 2 by my self, by replacing the string compares, with number compares! Simple. I do that almost on every point that profiler say that is slow. I change also all small points that can be even a little faster, and disable some not so used thinks. The results, 5% faster on NorthWind database, near 20% faster on my database with 250 tables. That is count with 500ms less in 10 seconds process on northwind, 100ms faster on my database on 500ms process time. I do not have captures to show you for that because I have made them with different code, different time, and track them down on paper. Anyway this is my story and my question on all that, what else do you know to make them even faster... For this measures I have use Subsonic 2.2 optimized by me, Subsonic 3.0.0.3 a little optimized by me, and Dot.Net 3.5

• Silverlight 4 + WCF RIA - Data Service Design Best Practices

  - by Chadd Nervig

  Hey all. I realize this is a rather long question, but I'd really appreciate any help from anyone experienced with RIA services. Thanks! I'm working on a Silverlight 4 app that views data from the server. I'm relatively inexperienced with RIA Services, so have been working through the tasks of getting the data I need down to the client, but every new piece I add to the puzzle seems to be more and more problematic. I feel like I'm missing some basic concepts here, and it seems like I'm just 'hacking' pieces on, in time-consuming ways, each one breaking the previous ones as I try to add them. I'd love to get the feedback of developers experienced with RIA services, to figure out the intended way to do what I'm trying to do. Let me lay out what I'm trying to do: First, the data. The source of this data is a variety of sources, primarily created by a shared library which reads data from our database, and exposes it as POCOs (Plain Old CLR Objects). I'm creating my own POCOs to represent the different types of data I need to pass between server and client. DataA - This app is for viewing a certain type of data, lets call DataA, in near-realtime. Every 3 minutes, the client should pull data down from the server, of all the new DataA since the last time it requested data. DataB - Users can view the DataA objects in the app, and may select one of them from the list, which displays additional details about that DataA. I'm bringing these extra details down from the server as DataB. DataC - One of the things that DataB contains is a history of a couple important values over time. I'm calling each data point of this history a DataC object, and each DataB object contains many DataCs. The Data Model - On the server side, I have a single DomainService: [EnableClientAccess] public class MyDomainService : DomainService { public IEnumerable<DataA> GetDataA(DateTime? startDate) { /*Pieces together the DataAs that have been created since startDate, and returns them*/ } public DataB GetDataB(int dataAID) { /*Looks up the extended info for that dataAID, constructs a new DataB with that DataA's data, plus the extended info (with multiple DataCs in a List<DataC> property on the DataB), and returns it*/ } //Not exactly sure why these are here, but I think it //wouldn't compile without them for some reason? The data //is entirely read-only, so I don't need to update. public void UpdateDataA(DataA dataA) { throw new NotSupportedException(); } public void UpdateDataB(DataB dataB) { throw new NotSupportedException(); } } The classes for DataA/B/C look like this: [KnownType(typeof(DataB))] public partial class DataA { [Key] [DataMember] public int DataAID { get; set; } [DataMember] public decimal MyDecimalA { get; set; } [DataMember] public string MyStringA { get; set; } [DataMember] public DataTime MyDateTimeA { get; set; } } public partial class DataB : DataA { [Key] [DataMember] public int DataAID { get; set; } [DataMember] public decimal MyDecimalB { get; set; } [DataMember] public string MyStringB { get; set; } [Include] //I don't know which of these, if any, I need? [Composition] [Association("DataAToC","DataAID","DataAID")] public List<DataC> DataCs { get; set; } } public partial class DataC { [Key] [DataMember] public int DataAID { get; set; } [Key] [DataMember] public DateTime Timestamp { get; set; } [DataMember] public decimal MyHistoricDecimal { get; set; } } I guess a big question I have here is... Should I be using Entities instead of POCOs? Are my classes constructed correctly to be able to pass the data down correctly? Should I be using Invoke methods instead of Query (Get) methods on the DomainService? On the client side, I'm having a number of issues. Surprisingly, one of my biggest ones has been threading. I didn't expect there to be so many threading issues with MyDomainContext. What I've learned is that you only seem to be able to create MyDomainContextObjects on the UI thread, all of the queries you can make are done asynchronously only, and that if you try to fake doing it synchronously by blocking the calling thread until the LoadOperation finishes, you have to do so on a background thread, since it uses the UI thread to make the query. So here's what I've got so far. The app should display a stream of the DataA objects, spreading each 3min chunk of them over the next 3min (so they end up displayed 3min after the occurred, looking like a continuous stream, but only have to be downloaded in 3min bursts). To do this, the main form initializes, creates a private MyDomainContext, and starts up a background worker, which continuously loops in a while(true). On each loop, it checks if it has any DataAs left over to display. If so, it displays that Data, and Thread.Sleep()s until the next DataA is scheduled to be displayed. If it's out of data, it queries for more, using the following methods: public DataA[] GetDataAs(DateTime? startDate) { _loadOperationGetDataACompletion = new AutoResetEvent(false); LoadOperation<DataA> loadOperationGetDataA = null; loadOperationGetDataA = _context.Load(_context.GetDataAQuery(startDate), System.ServiceModel.DomainServices.Client.LoadBehavior.RefreshCurrent, false); loadOperationGetDataA.Completed += new EventHandler(loadOperationGetDataA_Completed); _loadOperationGetDataACompletion.WaitOne(); List<DataA> dataAs = new List<DataA>(); foreach (var dataA in loadOperationGetDataA.Entities) dataAs.Add(dataA); return dataAs.ToArray(); } private static AutoResetEvent _loadOperationGetDataACompletion; private static void loadOperationGetDataA_Completed(object sender, EventArgs e) { _loadOperationGetDataACompletion.Set(); } Seems kind of clunky trying to force it into being synchronous, but since this already is on a background thread, I think this is OK? So far, everything actually works, as much of a hack as it seems like it may be. It's important to note that if I try to run that code on the UI thread, it locks, because it waits on the WaitOne() forever, locking the thread, so it can't make the Load request to the server. So once the data is displayed, users can click on one as it goes by to fill a details pane with the full DataB data about that object. To do that, I have the the details pane user control subscribing to a selection event I have setup, which gets fired when the selection changes (on the UI thread). I use a similar technique there, to get the DataB object: void SelectionService_SelectedDataAChanged(object sender, EventArgs e) { DataA dataA = /*Get the selected DataA*/; MyDomainContext context = new MyDomainContext(); var loadOperationGetDataB = context.Load(context.GetDataBQuery(dataA.DataAID), System.ServiceModel.DomainServices.Client.LoadBehavior.RefreshCurrent, false); loadOperationGetDataB.Completed += new EventHandler(loadOperationGetDataB_Completed); } private void loadOperationGetDataB_Completed(object sender, EventArgs e) { this.DataContext = ((LoadOperation<DataB>)sender).Entities.SingleOrDefault(); } Again, it seems kinda hacky, but it works... except on the DataB that it loads, the DataCs list is empty. I've tried all kinds of things there, and I don't see what I'm doing wrong to allow the DataCs to come down with the DataB. I'm about ready to make a 3rd query for the DataCs, but that's screaming even more hackiness to me. It really feels like I'm fighting against the grain here, like I'm doing this in an entirely unintended way. If anyone could offer any assistance, and point out what I'm doing wrong here, I'd very much appreciate it! Thanks!

• actionscript3: reflect-class applied on rotationY

  - by algro

  Hi, I'm using a class which applies a visual reflection-effect to defined movieclips. I use a reflection-class from here: link to source. It works like a charm except when I apply a rotation to the movieclip. In my case the reflection is still visible but only a part of it. What am I doing wrong? How could I pass/include the rotation to the Reflection-Class ? Thanks in advance! This is how you apply the Reflection Class to your movieclip: var ref_mc:MovieClip = new MoviClip(); addChild(ref_mc); var r1:Reflect = new Reflect({mc:ref_mc, alpha:50, ratio:50,distance:0, updateTime:0,reflectionDropoff:1}); Now I apply a rotation to my movieclip: ref_mc.rotationY = 30; And Here the Reflect-Class: package com.pixelfumes.reflect{ import flash.display.MovieClip; import flash.display.DisplayObject; import flash.display.BitmapData;

• Silverlight 2.0 - Can't get the text wrapping behaviour that I want

  - by Anthony

  I am having trouble getting Silverlight 2.0 to lay out text exactly how I want. I want text with line breaks and embedded links, with wrapping, like HTML text in a web page. Here's the closest that I have come: <UserControl x:Class="FlowPanelTest.Page" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:Controls="clr-namespace:Microsoft.Windows.Controls;assembly=Microsoft.Windows.Controls" Width="250" Height="300"> <Border BorderBrush="Black" BorderThickness="2" > <Controls:WrapPanel> <TextBlock x:Name="tb1" TextWrapping="Wrap">Short text. </TextBlock> <TextBlock x:Name="tb2" TextWrapping="Wrap">A bit of text. </TextBlock> <TextBlock x:Name="tb3" TextWrapping="Wrap">About half of a line of text.</TextBlock> <TextBlock x:Name="tb4" TextWrapping="Wrap">More than half a line of longer text.</TextBlock> <TextBlock x:Name="tb5" TextWrapping="Wrap">More than one line of text, so it will wrap onto the following line.</TextBlock> </Controls:WrapPanel> </Border> </UserControl> But the issue is that although the text blocks tb1 and tb2 will go onto the same line because there is room enough for them completely, tb3 onwards will not start on the same line as the previous block, even though it will wrap onto following lines. I want each text block to start where the previous one ends, on the same line. I want to put click event handlers on some of the text. I also want paragraph breaks. Essentially I'm trying to work around the lack of FlowDocument and Hyperlink controls in Silverlight 2.0's subset of XAML. To answer the questions posed in the answers: Why not use runs for the non-clickable text? If I just use individual TextBlocks only on the clickable text, then those bits of text will still suffer from the wrapping problem illustrated above. And the TextBlock just before the link, and the TextBlock just after. Essentially all of it. It doesn't look like I have many opportunities for putting multiple runs in the same TextBlock. Dividing the links from the other text with RegExs and loops is not the issue at all, the issue is display layout. Why not put each word in an individual TextBlock in a WrapPanel Aside from being an ugly hack, this does not play at all well with linebreaks - the layout is incorrect. It would also make the underline style of linked text into a broken line. Here's an example with each word in its own TextBlock. Try running it, note that the linebreak isn't shown in the right place at all. <UserControl x:Class="SilverlightApplication2.Page" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:Controls="clr-namespace:Microsoft.Windows.Controls;assembly=Microsoft.Windows.Controls" Width="300" Height="300"> <Controls:WrapPanel> <TextBlock TextWrapping="Wrap">Short1 </TextBlock> <TextBlock TextWrapping="Wrap">Longer1 </TextBlock> <TextBlock TextWrapping="Wrap">Longerest1 </TextBlock> <TextBlock TextWrapping="Wrap"> <Run>Break</Run> <LineBreak></LineBreak> </TextBlock> <TextBlock TextWrapping="Wrap">Short2</TextBlock> <TextBlock TextWrapping="Wrap">Longer2</TextBlock> <TextBlock TextWrapping="Wrap">Longerest2</TextBlock> <TextBlock TextWrapping="Wrap">Short3</TextBlock> <TextBlock TextWrapping="Wrap">Longer3</TextBlock> <TextBlock TextWrapping="Wrap">Longerest3</TextBlock> </Controls:WrapPanel> </UserControl> What about The LinkLabelControl as here and here. It has the same problems as the approach above, since it's much the same. Try running the sample, and make the link text longer and longer until it wraps. Note that the link starts on a new line, which it shouldn't. Make the link text even longer, so that the link text is longer than a line. Note that it doesn't wrap at all, it cuts off. This control doesn't handle line breaks and paragraph breaks either. Why not put the text all in runs, detect clicks on the containing TextBlock and work out which run was clicked Runs do not have mouse events, but the containing TextBlock does. I can't find a way to check if the run is under the mouse (IsMouseOver is not present in SilverLight) or to find the bounding geometry of the run (no clip property). There is VisualTreeHelper.FindElementsInHostCoordinates() The code below uses VisualTreeHelper.FindElementsInHostCoordinates to get the controls under the click. The output lists the TextBlock but not the Run, since a Run is not a UiElement. private void theText_MouseLeftButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e) { // get the elements under the click UIElement uiElementSender = sender as UIElement; Point clickPos = e.GetPosition(uiElementSender); var UiElementsUnderClick = VisualTreeHelper.FindElementsInHostCoordinates(clickPos, uiElementSender); // show the controls string outputText = ""; foreach (var uiElement in UiElementsUnderClick) { outputText += uiElement.GetType().ToString() + "\n"; } this.outText.Text = outputText; } Use an empty text block with a margin to space following content onto a following line I'm still thinking about this one. How do you calculate the right width for a line-breaking block to force following content onto the following line? Too short and the following content will still be on the same line, at the right. Too long and the "linebreak" will be on the following line, with content after it. You would have to resize the breaks when the control is resized. Some of the code for this is: TextBlock lineBreak = new TextBlock(); lineBreak.TextWrapping = TextWrapping.Wrap; lineBreak.Text = " "; // need adaptive width lineBreak.Margin = new Thickness(0, 0, 200, 0);

  Ok, so I've finally bowed to peer pressure and started using Spring in my web app :-)... So I'm trying to get the transaction handling stuff to work, and I just can't seem to get it. My Spring configuration looks like this: <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:p="http://www.springframework.org/schema/p" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <bean id="groupDao" class="mil.navy.ndms.conops.common.dao.impl.jpa.GroupDao" lazy-init="true"> <property name="entityManagerFactory" ><ref bean="entityManagerFactory"/></property> </bean> <!-- enables interpretation of the @Required annotation to ensure that dependency injection actually occures --> <bean class="org.springframework.beans.factory.annotation.RequiredAnnotationBeanPostProcessor"/> <!-- enables interpretation of the @PersistenceUnit/@PersistenceContext annotations providing convenient access to EntityManagerFactory/EntityManager --> <bean class="org.springframework.orm.jpa.support.PersistenceAnnotationBeanPostProcessor"/> <!-- uses the persistence unit defined in the META-INF/persistence.xml JPA configuration file --> <bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean"> <property name="persistenceUnitName" value="CONOPS_PU" /> </bean> <!-- transaction manager for use with a single JPA EntityManagerFactory for transactional data access to a single datasource --> <bean id="jpaTransactionManager" class="org.springframework.orm.jpa.JpaTransactionManager"> <property name="entityManagerFactory" ref="entityManagerFactory"/> </bean> <!-- enables interpretation of the @Transactional annotation for declerative transaction managment using the specified JpaTransactionManager --> <tx:annotation-driven transaction-manager="jpaTransactionManager" proxy-target-class="true"/> </beans> persistence.xml: <?xml version="1.0" encoding="UTF-8"?> <persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"> <persistence-unit name="CONOPS_PU" transaction-type="RESOURCE_LOCAL"> <provider>org.hibernate.ejb.HibernatePersistence</provider> ...

• What pseudo-operators exist in Perl 5?

  - by Chas. Owens

  I am currently documenting all of Perl 5's operators (see the perlopref GitHub project) and I have decided to include Perl 5's pseudo-operators as well. To me, a pseudo-operator in Perl is anything that looks like an operator, but is really more than one operator or a some other piece of syntax. I have documented the four I am familiar with already: ()= the countof operator =()= the goatse/countof operator ~~ the scalar context operator }{ the Eskimo-kiss operator What other names exist for these pseudo-operators, and do you know of any pseudo-operators I have missed? =head1 Pseudo-operators There are idioms in Perl 5 that appear to be operators, but are really a combination of several operators or pieces of syntax. These pseudo-operators have the precedence of the constituent parts. =head2 ()= X =head3 Description This pseudo-operator is the list assignment operator (aka the countof operator). It is made up of two items C<()>, and C<=>. In scalar context it returns the number of items in the list X. In list context it returns an empty list. It is useful when you have something that returns a list and you want to know the number of items in that list and don't care about the list's contents. It is needed because the comma operator returns the last item in the sequence rather than the number of items in the sequence when it is placed in scalar context. It works because the assignment operator returns the number of items available to be assigned when its left hand side has list context. In the following example there are five values in the list being assigned to the list C<($x, $y, $z)>, so C<$count> is assigned C<5>. my $count = my ($x, $y, $z) = qw/a b c d e/; The empty list (the C<()> part of the pseudo-operator) triggers this behavior. =head3 Example sub f { return qw/a b c d e/ } my $count = ()= f(); #$count is now 5 my $string = "cat cat dog cat"; my $cats = ()= $string =~ /cat/g; #$cats is now 3 print scalar( ()= f() ), "\n"; #prints "5\n" =head3 See also L</X = Y> and L</X =()= Y> =head2 X =()= Y This pseudo-operator is often called the goatse operator for reasons better left unexamined; it is also called the list assignment or countof operator. It is made up of three items C<=>, C<()>, and C<=>. When X is a scalar variable, the number of items in the list Y is returned. If X is an array or a hash it it returns an empty list. It is useful when you have something that returns a list and you want to know the number of items in that list and don't care about the list's contents. It is needed because the comma operator returns the last item in the sequence rather than the number of items in the sequence when it is placed in scalar context. It works because the assignment operator returns the number of items available to be assigned when its left hand side has list context. In the following example there are five values in the list being assigned to the list C<($x, $y, $z)>, so C<$count> is assigned C<5>. my $count = my ($x, $y, $z) = qw/a b c d e/; The empty list (the C<()> part of the pseudo-operator) triggers this behavior. =head3 Example sub f { return qw/a b c d e/ } my $count =()= f(); #$count is now 5 my $string = "cat cat dog cat"; my $cats =()= $string =~ /cat/g; #$cats is now 3 =head3 See also L</=> and L</()=> =head2 ~~X =head3 Description This pseudo-operator is named the scalar context operator. It is made up of two bitwise negation operators. It provides scalar context to the expression X. It works because the first bitwise negation operator provides scalar context to X and performs a bitwise negation of the result; since the result of two bitwise negations is the original item, the value of the original expression is preserved. With the addition of the Smart match operator, this pseudo-operator is even more confusing. The C<scalar> function is much easier to understand and you are encouraged to use it instead. =head3 Example my @a = qw/a b c d/; print ~~@a, "\n"; #prints 4 =head3 See also L</~X>, L</X ~~ Y>, and L<perlfunc/scalar> =head2 X }{ Y =head3 Description This pseudo-operator is called the Eskimo-kiss operator because it looks like two faces touching noses. It is made up of an closing brace and an opening brace. It is used when using C<perl> as a command-line program with the C<-n> or C<-p> options. It has the effect of running X inside of the loop created by C<-n> or C<-p> and running Y at the end of the program. It works because the closing brace closes the loop created by C<-n> or C<-p> and the opening brace creates a new bare block that is closed by the loop's original ending. You can see this behavior by using the L<B::Deparse> module. Here is the command C<perl -ne 'print $_;'> deparsed: LINE: while (defined($_ = <ARGV>)) { print $_; } Notice how the original code was wrapped with the C<while> loop. Here is the deparsing of C<perl -ne '$count++ if /foo/; }{ print "$count\n"'>: LINE: while (defined($_ = <ARGV>)) { ++$count if /foo/; } { print "$count\n"; } Notice how the C<while> loop is closed by the closing brace we added and the opening brace starts a new bare block that is closed by the closing brace that was originally intended to close the C<while> loop. =head3 Example # count unique lines in the file FOO perl -nle '$seen{$_}++ }{ print "$_ => $seen{$_}" for keys %seen' FOO # sum all of the lines until the user types control-d perl -nle '$sum += $_ }{ print $sum' =head3 See also L<perlrun> and L<perlsyn> =cut

• PHP/MySQL Swap places in database + JavaScript (jQuery)

  - by James Brooks

  I'm currently developing a website which stores bookmarks in a MySQL database using PHP and jQuery. The MySQL for bookmarks looks like this (CSV format): id,userid,link_count,url,title,description,tags,shareid,fav,date "1";"1";"0";"img/test/google.png";"Google";"Best. Search Engine. Ever.";"google, search, engine";"7nbsp";"0";"1267578934" "2";"1";"1";"img/test/james-brooks.png";"jTutorials";"Best. jQuery Tutorials.

Here is the JavaScript code I use to format the bookmarks and post the data to the PHP page: $(".bookmarks").sortable({scroll: false, update: function(event, ui){ // Update bookmark position in the database when the bookmark is dropped var newItems = $("ul.bookmarks").sortable('toArray'); console.log(newItems); var oldItems = ""; for(var imgI=0;imgI < newItems.length;imgI++) { oldItems += $("ul.bookmarks li#" + imgI + " img").attr("id") + ","; } oldItems = oldItems.slice(0, oldItems.length-1); console.log("New position: " + newItems); console.log("Old position: " + oldItems); // Post the data $.post('inc/updateBookmarks.php', 'update=true&olditems=' + oldItems + "&newitems=" + newItems, function(r) { console.log(r); }); } }); The PHP page then goes about splitting the posted arrays using explode, like so: if(isset($pstUpdate)) { // Get the current and new positions $arrOldItems = $_POST['olditems']; $arrOldItems = explode(",", $arrOldItems); $arrNewItems = $_POST['newitems']; $arrNewItems = explode(",", $arrNewItems); // Get the user id $usrID = $U->user_field('id'); // Update the old place to the new one for($anID=0;$anID<count($arrOldItems);$anID++) { //echo "UPDATE linkz SET link_count='" . $arrNewItems[$anID] . "' WHERE userid='" . $usrID . "' AND link_count='" . $arrOldItems[$anID] . "'\n"; //echo "SELECT id FROM linkz WHERE link_id='".$arrOldItems[$anID]."' AND userid='".$usrID."'"; $curLinkID = mysql_fetch_array(mysql_query("SELECT id FROM linkz WHERE link_count='".$arrOldItems[$anID]."' AND userid='".$usrID."'")) or die(mysql_error()); echo $arrOldItems[$anID] . " => " . $arrNewItems[$anID] . " => " . $curLinkID['id'] . "\n"; //mysql_query("UPDATE linkz SET link_count='" . $arrNewItems[$anID] . "' WHERE userid='" . $usrID . "' AND link_count='" . $curLinkID['id'] . "'") or die(mysql_error()); // Join a string with the new positions $outPos .= $arrNewItems[$anID] . "|"; } echo substr($outPos, 0, strlen($outPost) - 1); } So, each bookmark is given it's own link_count id (which starts from 0 for each user). Every time a bookmark is changed, I need the link_count to be changed as needed. If we take this array output as the starting places: Array ( [0] => 0 [1] => 1 [2] => 2 [3] => 3 [4] => 4 [5] => 5 ) Each index equalling the link_count position, the resulting update would become: Array ( [0] => 1 [1] => 0 [2] => 3 [3] => 4 [4] => 5 [5] => 2 ) I have tried many ways but none are successful. Thanks in advance.

• Questions related to writing your own file downloader using multiple threads java

  - by Shekhar

  Hello In my current company, i am doing a PoC on how we can write a file downloader utility. We have to use socket programming(TCP/IP) for downloading the files. One of the requirements of the client is that a file(which will be large in size) should be transfered in chunks for example if we have a file of 5Mb size then we can have 5 threads which transfer 1 Mb each. I have written a small application which downloads a file. You can download the eclipe project from http://www.fileflyer.com/view/QM1JSC0 A brief explanation of my classes FileSender.java This class provides the bytes of file. It has a method called sendBytesOfFile(long start,long end, long sequenceNo) which gives the number of bytes. import java.io.File; import java.io.IOException; import java.util.zip.CRC32; import org.apache.commons.io.FileUtils; public class FileSender { private static final String FILE_NAME = "C:\\shared\\test.pdf"; public ByteArrayWrapper sendBytesOfFile(long start,long end, long sequenceNo){ try { File file = new File(FILE_NAME); byte[] fileBytes = FileUtils.readFileToByteArray(file); System.out.println("Size of file is " +fileBytes.length); System.out.println(); System.out.println("Start "+start +" end "+end); byte[] bytes = getByteArray(fileBytes, start, end); ByteArrayWrapper wrapper = new ByteArrayWrapper(bytes, sequenceNo); return wrapper; } catch (IOException e) { throw new RuntimeException(e); } } private byte[] getByteArray(byte[] bytes, long start, long end){ long arrayLength = end-start; System.out.println("Start : "+start +" end : "+end + " Arraylength : "+arrayLength +" length of source array : "+bytes.length); byte[] arr = new byte[(int)arrayLength]; for(int i = (int)start, j =0; i < end;i++,j++){ arr[j] = bytes[i]; } return arr; } public static long fileSize(){ File file = new File(FILE_NAME); return file.length(); } } Second Class is FileReceiver.java - This class receives the file. Small Explanation what this file does This class finds the size of the file to be fetched from Sender Depending upon the size of the file it finds the start and end position till the bytes needs to be read. It starts n number of threads giving each thread start,end, sequence number and a list which all the threads share. Each thread reads the number of bytes and creates a ByteArrayWrapper. ByteArrayWrapper objects are added to the list Then i have while loop which basically make sure that all threads have done their work finally it sorts the list based on the sequence number. then the bytes are joined, and a complete byte array is formed which is converted to a file. Code of File Receiver package com.filedownloader; import java.io.File; import java.io.IOException; import java.util.ArrayList; import java.util.Collections; import java.util.Comparator; import java.util.List; import java.util.zip.CRC32; import org.apache.commons.io.FileUtils; public class FileReceiver { public static void main(String[] args) { FileReceiver receiver = new FileReceiver(); receiver.receiveFile(); } public void receiveFile(){ long startTime = System.currentTimeMillis(); long numberOfThreads = 10; long filesize = FileSender.fileSize(); System.out.println("File size received "+filesize); long start = filesize/numberOfThreads; List<ByteArrayWrapper> list = new ArrayList<ByteArrayWrapper>(); for(long threadCount =0; threadCount<numberOfThreads ;threadCount++){ FileDownloaderTask task = new FileDownloaderTask(threadCount*start,(threadCount+1)*start,threadCount,list); new Thread(task).start(); } while(list.size() != numberOfThreads){ // this is done so that all the threads should complete their work before processing further. //System.out.println("Waiting for threads to complete. List size "+list.size()); } if(list.size() == numberOfThreads){ System.out.println("All bytes received "+list); Collections.sort(list, new Comparator<ByteArrayWrapper>() { @Override public int compare(ByteArrayWrapper o1, ByteArrayWrapper o2) { long sequence1 = o1.getSequence(); long sequence2 = o2.getSequence(); if(sequence1 < sequence2){ return -1; }else if(sequence1 > sequence2){ return 1; } else{ return 0; } } }); byte[] totalBytes = list.get(0).getBytes(); byte[] firstArr = null; byte[] secondArr = null; for(int i = 1;i<list.size();i++){ firstArr = totalBytes; secondArr = list.get(i).getBytes(); totalBytes = concat(firstArr, secondArr); } System.out.println(totalBytes.length); convertToFile(totalBytes,"c:\\tmp\\test.pdf"); long endTime = System.currentTimeMillis(); System.out.println("Total time taken with "+numberOfThreads +" threads is "+(endTime-startTime)+" ms" ); } } private byte[] concat(byte[] A, byte[] B) { byte[] C= new byte[A.length+B.length]; System.arraycopy(A, 0, C, 0, A.length); System.arraycopy(B, 0, C, A.length, B.length); return C; } private void convertToFile(byte[] totalBytes,String name) { try { FileUtils.writeByteArrayToFile(new File(name), totalBytes); } catch (IOException e) { throw new RuntimeException(e); } } } Code of ByteArrayWrapper package com.filedownloader; import java.io.Serializable; public class ByteArrayWrapper implements Serializable{ private static final long serialVersionUID = 3499562855188457886L; private byte[] bytes; private long sequence; public ByteArrayWrapper(byte[] bytes, long sequenceNo) { this.bytes = bytes; this.sequence = sequenceNo; } public byte[] getBytes() { return bytes; } public long getSequence() { return sequence; } } Code of FileDownloaderTask import java.util.List; public class FileDownloaderTask implements Runnable { private List<ByteArrayWrapper> list; private long start; private long end; private long sequenceNo; public FileDownloaderTask(long start,long end,long sequenceNo,List<ByteArrayWrapper> list) { this.list = list; this.start = start; this.end = end; this.sequenceNo = sequenceNo; } @Override public void run() { ByteArrayWrapper wrapper = new FileSender().sendBytesOfFile(start, end, sequenceNo); list.add(wrapper); } } Questions related to this code 1) Does file downloading becomes fast when multiple threads is used? In this code i am not able to see the benefit. 2) How should i decide how many threads should i create ? 3) Are their any opensource libraries which does that 4) The file which file receiver receives is valid and not corrupted but checksum (i used FileUtils of common-io) does not match. Whats the problem? 5) This code gives out of memory when used with large file(above 100 Mb) i.e. because byte array which is created. How can i avoid? I know this is a very bad code but i have to write this in one day -:). Please suggest any other good way to do this? Thanks Shekhar

• AS3 XML Slideshow Woes

  - by Chris

  Hello All, I am hoping someone out there can possibly shed some light on a couple issues I am having with an image slideshow I have been working on a simple slideshow for a project and everything was going great/as expected up until I created a function to hide the previous images before displaying the next. On the first pass through everything seems to run fine; once the slideshow starts over, the images don't show up, yet when it goes to load the following image, it plays the tween from the hide previous function which shows the image briefly before fading out. So essentially the display is blank, then the timer calls in the next slide and its a brief flash of an image fading out, and then blank again. Another issue I am having is the text that I am loading in from the XML does not seem to want to tween in or out as they are supposed to. Here is the code: import fl.transitions.Tween; import fl.transitions.easing.*; import fl.transitions.TweenEvent; import flash.display.BitmapData; import flash.display.Bitmap; import flash.display.Sprite; import flash.utils.Timer; import flash.events.TimerEvent; var filePath:String = "photo1.xml"; var iArray:Array = new Array(); var titleArray:Array = new Array(); var dateArray:Array = new Array(); var catArray:Array = new Array();

catContainer.removeChildAt(0); descContainer.removeChildAt(0); } I'm no flash whiz, bet can generally figure most issues out by either analyzing the code, or digging around online; however, this has me stumped. Any help would really be appreciated, and I thank you all in advance.

• Client no longer getting data from Web Service after introducing targetNamespace in XSD

  - by Laurence

  Sorry if there is way too much info in this post – there’s a load of story before I get to the actual problem. I thought I‘d include everything that might be relevant as I don’t have much clue what is wrong. I had a working web service and client (both written with VS 2008 in C#) for passing product data to an e-commerce site. The XSD started like this: <xs:schema id="Ecommerce" elementFormDefault="qualified" xmlns:mstns="http://tempuri.org/Ecommerce.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="eur"> <xs:complexType> <xs:sequence> <xs:element ref="sec" minOccurs="1" maxOccurs="1"/> </xs:sequence> etc Here’s a sample document sent from client to service: <eur xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" class="ECommerce_WebService" type="product" method="GetLastDateSent" chunk_no="1" total_chunks="1" date_stamp="2010-03-10T17:16:34.523" version="1.1"> <sec guid="BFBACB3C-4C17-4786-ACCF-96BFDBF32DA5" company_name="Company" version="1.1"> <data /> </sec> </eur> Then, I had to give the service a targetNamespace. Actually I don’t know if I “had” to set it, but I added (to the same VS project) some code to act as a client to a completely unrelated service (which also had no namespace), and the project would not build until I gave my service a namespace. Now the XSD starts like this: <xs:schema id="Ecommerce" elementFormDefault="qualified" xmlns:mstns="http://tempuri.org/Ecommerce.xsd" xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="http://www.company.com/ecommerce" xmlns:ecom="http://www. company.com/ecommerce"> <xs:element name="eur"> <xs:complexType> <xs:sequence> <xs:element ref="ecom:sec" minOccurs="1" maxOccurs="1" /> </xs:sequence> etc As you can see above I also updated all the xs:element ref attributes to give them the “ecom” prefix. Now the project builds again. I found the client needed some modification after this. The client uses a SQL stored procedure to generate the XML. This is then de-serialised into an object of the correct type for the service’s “get_data” method. The object’s type used to be “eur” but after updating the web reference to the service, it became “get_dataEur”. And sure enough the parent element in the XML had to be changed to “get_dataEur” to be accepted. Then bizarrely I also had to put the xmlns attribute containing my namespace on the “sec” element (the immediate child of the parent element) rather than the parent element. Here’s a sample document now sent from client to service: <get_dataEur xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" class="ECommerce_WebService" type="product" method="GetLastDateSent" chunk_no="1" total_chunks="1" date_stamp="2010-03-10T18:23:20.653" version="1.1"> <sec xmlns="http://www.company.com/ecommerce" guid="BFBACB3C-4C17-4786-ACCF-96BFDBF32DA5" company_name="Company" version="1.1"> <data /> </sec> </get_dataEur> If in the service’s get_data method I then serialize the incoming object I see this (the parent element is “eur” and the xmlns attribute is on the parent element): <eur xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.company.com/ecommerce" class="ECommerce_WebService" type="product" method="GetLastDateSent" chunk_no="1" total_chunks="1" date_stamp="2010-03-10T18:23:20.653" version="1.1"> <sec guid="BFBACB3C-4C17-4786-ACCF-96BFDBF32DA5" company_name="Company" version="1.1"> <data /> </sec> </eur> The service then prepares a reply to go back to the client. The XML looks like this (the important data being sent back is the date_stamp attribute in the last_sent element): <eur xmlns="http://www.company.com/ecommerce" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" class="ECommerce_WebService" type="product" method="GetLastDateSent" chunk_no="1" total_chunks="1" date_stamp="2010-03-10T18:22:57.530" version="1.1"> <sec version="1.1" xmlns=""> <data> <last_sent date_stamp="2010-02-25T15:15:10.193" /> </data> </sec> </eur> Now finally, here’s the problem!!! The client does not see any data – all it sees is the parent element with nothing inside it. If I serialize the reply object in the client code it looks like this: <get_dataResponseEur xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" class="ECommerce_WebService" type="product" method="GetLastDateSent" chunk_no="1" total_chunks="1" date_stamp="2010-03-10T18:22:57.53" version="1.1" /> So, my questions are: why isn’t my client seeing the contents of the reply document? how do I fix it? why do I have to put the xmlns attribute on a child element rather than the parent element in the outgoing document? Here’s a bit more possibly relevant info: The client code (pre-namespace) called the service method like this: XmlSerializer serializer = new XmlSerializer(typeof(eur)); XmlReader reader = xml.CreateReader(); eur eur = (eur)serializer.Deserialize(reader); service.Credentials = new NetworkCredential(login, pwd); service.Url = url; rc = service.get_data(ref eur); After the namespace was added I had to change it to this: XmlSerializer serializer = new XmlSerializer(typeof(get_dataEur)); XmlReader reader = xml.CreateReader(); get_dataEur eur = (get_dataEur)serializer.Deserialize(reader); get_dataResponseEur eur1 = new get_dataResponseEur(); service.Credentials = new NetworkCredential(login, pwd); service.Url = url; rc = service.get_data(eur, out eur1);

• How to know if the client has terminated in sockets

  - by shadyabhi

  Suppose, I have a connected socket after writing this code.. if ((sd = accept(socket_d, (struct sockaddr *)&client_addr, &alen)) < 0) { perror("accept failed\n"); exit(1); } How can I know at the server side that client has exited. My whole program actually does the following.. Accepts a connection from client Starts a new thread that reads messages from that particular client and then broadcast this message to all the connected clients. If you want to see the whole code... In this whole code. I am also struggling with one more problem that whenever I kill a client with Ctrl+C, my server terminates abruptly..

• parallelizing code using openmp

  - by anubhav

  Hi, The function below contains nested for loops. There are 3 of them. I have given the whole function below for easy understanding. I want to parallelize the code in the innermost for loop as it takes maximum CPU time. Then i can think about outer 2 for loops. I can see dependencies and internal inline functions in the innermost for loop . Can the innermost for loop be rewritten to enable parallelization using openmp pragmas. Please tell how.

• cannot delete from doubly linked list using visual studios in C

  - by Jesus Sanchez

  hello I am currently doing an assignment that is supposed to read in a file, use the information, and then print out another file. all using doubly linked list. Currently i am trying to just read in the file into a doubly linked list, print it out onto the screen and a file, and finally delete the list and close the program. The program works fine as long as I don't call the dlist_distroy function which is supposed to delete the string. as soon as I do it the program starts running and then a window pops up saying "Windows has triggered a breakpoint in tempfilter.exe. This may be due to a corruption of the heap, which indicates a bug in tempfilter.exe or any of the DLLs it has loaded. This may also be due to the user pressing F12 while tempfilter.exe has focus. The output window may have more diagnostic information." I have revised the destroy and remove functions and cant understand the problem. my program is the following main.c #include <stdlib.h> #include <stdio.h> #include <string.h> #include "dlinklist.h" #include "DlistElmt.h" #include "Dlist.h" #include "dlistdata.h" /**************************************************************************************************/ int main ( int argc, char *argv[] ) { FILE *ifp, *ofp; int hour, min; Dlist *list; DlistElmt *current=NULL, *element; float temp; list = (Dlist *)malloc(sizeof(list)); element = (DlistElmt *)malloc(sizeof(element)); if ( argc != 3 ) /* argc should be 3 for correct execution */ { /* We print argv[0] assuming it is the program name */ /* TODO: This is wrong, it should be: usage: %s inputfile outputfile */ printf( "usage: %s filename", argv[0] ); } else { // We assume argv[1] is a filename to open ifp = fopen( argv[1], "r" ); if (ifp == 0 ){ printf("Could not open file\n"); } else{ ofp = fopen(argv[2], "w"); dlist_init(list);//, (destroy)(hour, min, temp)); while (fscanf(ifp, "%d:%d %f ", &hour, &min, &temp) == 3) { current=list->tail; if(dlist_size(list)==0){ dlist_ins_prev(list, current, hour, min, temp); } else{ dlist_ins_next(list, current, hour, min, temp); } } current = list->head; while(current != NULL){ if(current==list->head){ current=current->next; } else if((current->temp > (current->prev->temp +5)) || (current->temp < (current->prev->temp -5))){ dlist_remove(list, current); current=current->next; } else current=current->next; } current = list->head; while(current != NULL){ printf("%d:%d %2.1lf\n" ,current->time, current->time2, current->temp ); fprintf(ofp, "%d:%d %2.1lf\n", current->time, current->time2, current->temp ); current = current->next; } //dlist_destroy(list); //} fclose(ifp); fclose(ofp); } } getchar(); } dlistdata.c #include <stdlib.h> #include <stdio.h> #include <string.h> #include "dlinklist.h" #include "DlistElmt.h" #include "dlistdata.h" /**************************************************************************************************/ void dlist_init(Dlist *list){ list->size = 0; list->head = NULL; list->tail = NULL; return; } void dlist_destroy(Dlist *list){ while (dlist_size(list) > 0){ dlist_remove(list, list->head); } memset(list, 0, sizeof(Dlist)); return; } int dlist_ins_next(Dlist *list, DlistElmt *element, const int time, const int time2, const float temp){ DlistElmt *new_element; if (element == NULL && dlist_size(list) != 0) return -1; if ((new_element = (DlistElmt *)malloc(sizeof(new_element))) == NULL) return -1; new_element->time = (int )time; new_element->time2 = (int )time2; new_element->temp = (float )temp; if (dlist_size(list) == 0) { list->head = new_element; list->head->prev = NULL; list->head->next = NULL; list->tail = new_element; } else { new_element->next = element->next; new_element->prev = element; if(element->next == NULL) list->tail = new_element; else element->next->prev = new_element; element->next = new_element; } list->size++; return 0; } int dlist_ins_prev(Dlist *list, DlistElmt *element, const int time, const int time2, const float temp){ DlistElmt *new_element; if (element == NULL && dlist_size(list) != 0) return -1; if ((new_element = (DlistElmt *)malloc(sizeof(new_element))) == NULL) return -1; new_element->time = (int )time; new_element->time2 = (int )time2; new_element->temp = (float )temp; if (dlist_size(list) == 0){ list->head = new_element; list->head->prev = NULL; list->head->next=NULL; list->tail = new_element; } else{ new_element->next = element; new_element->prev = element->prev; if(element->prev ==NULL) list->head = new_element; else element->prev->next = new_element; element->prev = new_element; } list->size++; return 0; } int dlist_remove(Dlist *list, DlistElmt *element){//, int time, int time2, float temp){ if (element == NULL || dlist_size(list) == 0) return -1; if (element == list->head) { list->head = element->next; if (list->head == NULL) list->tail = NULL; else element->next->prev = NULL; } else{ element->prev->next = element->next; if (element->next = NULL) list->tail = element->prev; else element->next->prev = element->prev; } free(element); list->size--; return 0; }

• Ajax, Callback, postback and Sys.WebForms.PageRequestManager.getInstance().add_beginRequest

  - by user338262

  Hi, I have a user control which encapsulates a NumericUpDownExtender. This UserControl implements the interface ICallbackEventHandler, because I want that when a user changes the value of the textbox associated a custom event to be raised in the server. By the other hand each time an async postback is done I shoe a message of loading and disable the whole screen. This works perfect when something is changed in for example an UpdatePanel through this lines of code: Sys.WebForms.PageRequestManager.getInstance().add_beginRequest( function (sender, args) { var modalPopupBehavior = $find('programmaticSavingLoadingModalPopupBehavior'); modalPopupBehavior.show(); } ); The UserControl is placed inside a detailsview which is inside an UpdatePanel in an aspx. When the custom event is raised I want another textbox in the aspx to change its value. So far, When I click on the UpDownExtender, it goes correctly to the server and raises the custom event, and the new value of the textbox is assigned in the server. but it is not changed in the browser. I suspect that the problem is the callback, since I have the same architecture for a UserControl with an AutoCompleteExtender which implement IPostbackEventHandler and it works. Any clues how can I solve this here to make the UpDownNumericExtender user control to work like the AutComplete one? This is the code of the user control and the parent: using System; using System.Web.UI; using System.ComponentModel; using System.Text; namespace Corp.UserControls { [Themeable(true)] public partial class CustomNumericUpDown : CorpNumericUpDown, ICallbackEventHandler { protected void Page_PreRender(object sender, EventArgs e) { if (!Page.IsPostBack) { currentInstanceNumber = CorpAjaxControlToolkitUserControl.getNextInstanceNumber(); } registerControl(this.HFNumericUpDown.ClientID, currentInstanceNumber); string strCallServer = "NumericUpDownCallServer" + currentInstanceNumber.ToString(); // If this function is not written the callback to get the disponibilidadCliente doesn't work if (!Page.ClientScript.IsClientScriptBlockRegistered("ReceiveServerDataNumericUpDown")) { StringBuilder str = new StringBuilder(); str.Append("function ReceiveServerDataNumericUpDown(arg, context) {}").AppendLine(); Page.ClientScript.RegisterClientScriptBlock(typeof(CorpNumericUpDown), "ReceiveServerDataNumericUpDown", str.ToString(), true); } nudeNumericUpDownExtender.BehaviorID = "NumericUpDownEx" + currentInstanceNumber.ToString(); ClientScriptManager cm = Page.ClientScript; String cbReference = cm.GetCallbackEventReference(this, "arg", "ReceiveServerDataNumericUpDown", ""); String callbackScript = "function " + strCallServer + "(arg, context)" + Environment.NewLine + "{" + Environment.NewLine + cbReference + ";" + Environment.NewLine + "}" + Environment.NewLine; cm.RegisterClientScriptBlock(typeof(CustomNumericUpDown), strCallServer, callbackScript, true); base.Page_PreRender(sender,e); } [System.ComponentModel.Browsable(true)] [System.ComponentModel.Bindable(true)] public Int64 Value { get { return (string.IsNullOrEmpty(HFNumericUpDown.Value) ? Int64.Parse("1") : Int64.Parse(HFNumericUpDown.Value)); } set { HFNumericUpDown.Value = value.ToString(); //txtAutoCompleteCliente_AutoCompleteExtender.ContextKey = value.ToString(); // TODO: Change the text of the textbox } } [System.ComponentModel.Browsable(true)] [System.ComponentModel.Bindable(true)] [Description("The text of the numeric up down")] public string Text { get { return txtNumericUpDown.Text; } set { txtNumericUpDown.Text = value; } } public delegate void NumericUpDownChangedHandler(object sender, NumericUpDownChangedArgs e); public event NumericUpDownChangedHandler numericUpDownEvent; [System.ComponentModel.Browsable(true)] [System.ComponentModel.Bindable(true)] [System.ComponentModel.Description("Raised after the number has been increased or decreased")] protected virtual void OnNumericUpDownEvent(object sender, NumericUpDownChangedArgs e) { if (numericUpDownEvent != null) //check to see if anyone has attached to the event numericUpDownEvent(this, e); } #region ICallbackEventHandler Members public string GetCallbackResult() { return "";//throw new NotImplementedException(); } public void RaiseCallbackEvent(string eventArgument) { NumericUpDownChangedArgs nudca = new NumericUpDownChangedArgs(long.Parse(eventArgument)); OnNumericUpDownEvent(this, nudca); } #endregion } /// <summary> /// Class that adds the prestamoList to the event /// </summary> public class NumericUpDownChangedArgs : System.EventArgs { /// <summary> /// The current selected value. /// </summary> public long Value { get; private set; } public NumericUpDownChangedArgs(long value) { Value = value; } } } using System; using System.Collections.Generic; using System.Text; namespace Corp { /// <summary> /// Summary description for CorpAjaxControlToolkitUserControl /// </summary> public class CorpNumericUpDown : CorpAjaxControlToolkitUserControl { private Int16 _currentInstanceNumber; // This variable hold the instanceNumber assignated at first place. public short currentInstanceNumber { get { return _currentInstanceNumber; } set { _currentInstanceNumber = value; } } protected void Page_PreRender(object sender, EventArgs e) { const string strOnChange = "OnChange"; const string strCallServer = "NumericUpDownCallServer"; StringBuilder str = new StringBuilder(); foreach (KeyValuePair<String, Int16> control in controlsToRegister) { str.Append("function ").Append(strOnChange + control.Value).Append("(sender, eventArgs) ").AppendLine(); str.Append("{").AppendLine(); str.Append(" if (sender) {").AppendLine(); str.Append(" var hfield = document.getElementById('").Append(control.Key).Append("');").AppendLine(); str.Append(" if (hfield.value != eventArgs) {").AppendLine(); str.Append(" hfield.value = eventArgs;").AppendLine(); str.Append(" ").Append(strCallServer + control.Value).Append("(eventArgs, eventArgs);").AppendLine(); str.Append(" }").AppendLine(); str.Append(" }").AppendLine(); str.Append("}").AppendLine(); Page.ClientScript.RegisterClientScriptBlock(typeof(CorpNumericUpDown), Guid.NewGuid().ToString(), str.ToString(), true); } str = new StringBuilder(); foreach (KeyValuePair<String, Int16> control in controlsToRegister) { str.Append(" funcsPageLoad[funcsPageLoad.length] = function() { $find('NumericUpDownEx" + control.Value + "').add_currentChanged(").Append(strOnChange + control.Value).Append(");};").AppendLine(); str.Append(" funcsPageUnLoad[funcsPageUnLoad.length] = function() { $find('NumericUpDownEx" + control.Value + "').remove_currentChanged(").Append(strOnChange + control.Value).Append(");};").AppendLine(); } Page.ClientScript.RegisterClientScriptBlock(typeof(CorpNumericUpDown), Guid.NewGuid().ToString(), str.ToString(), true); } } } and to create the loading view I use this: //The beginRequest event is raised before the processing of an asynchronous postback starts and the postback is sent to the server. You can use this event to call custom script to set a request header or to start an animation that notifies the user that the postback is being processed. Sys.WebForms.PageRequestManager.getInstance().add_beginRequest( function (sender, args) { var modalPopupBehavior = $find('programmaticSavingLoadingModalPopupBehavior'); modalPopupBehavior.show(); } ); //The endRequest event is raised after an asynchronous postback is finished and control has been returned to the browser. You can use this event to provide a notification to users or to log errors. Sys.WebForms.PageRequestManager.getInstance().add_endRequest( function (sender, arg) { var modalPopupBehavior = $find('programmaticSavingLoadingModalPopupBehavior'); modalPopupBehavior.hide(); } ); Thanks in advance!

• .NET Regex: Howto extract IPv6 address parts

  - by Quandary

  Question: How does the .NET regex string to extract IPv6 addresses look like ? I can get it to extract a simple IPv6 address like "1050:0:0:0:5:600:300c:326b" but not the colon format ("ff06::c3"); My problem is, it should extract a 0 for every omitted value between the :: How do I do that? Below my code + description. Specify IPv6 addresses by omitting leading zeros. For example, IPv6 address 1050:0000:0000:0000:0005:0600:300c:326b may be written as 1050:0:0:0:5:600:300c:326b. Double colon Specify IPv6 addresses by using double colons (::) in place of a series of zeros. For example, IPv6 address ff06:0:0:0:0:0:0:c3 may be written as ff06::c3. Double colons may be used only once in an IP address. strInputString = "ff06::c3"; strInputString = "1050:0000:0000:0000:0005:0600:300c:326b"; string strPattern = "([A-Fa-f0-9]{1,4}:){7}([A-Fa-f0-9]{1,4})"; //strPattern = @"\A(?:[0-9a-fA-F]{1,4}:){7}[0-9a-fA-F]{1,4}\z"; //strPattern = @"(\A([0-9a-f]{1,4}:){1,1}(:[0-9a-f]{1,4}){1,6}\Z)|(\A([0-9a-f]{1,4}:){1,2}(:[0-9a-f]{1,4}){1,5}\Z)|(\A([0-9a-f]{1,4}:){1,3}(:[0-9a-f]{1,4}){1,4}\Z)|(\A([0-9a-f]{1,4}:){1,4}(:[0-9a-f]{1,4}){1,3}\Z)|(\A([0-9a-f]{1,4}:){1,5}(:[0-9a-f]{1,4}){1,2}\Z)|(\A([0-9a-f]{1,4}:){1,6}(:[0-9a-f]{1,4}){1,1}\Z)|(\A(([0-9a-f]{1,4}:){1,7}|:):\Z)|(\A:(:[0-9a-f]{1,4}){1,7}\Z)|(\A((([0-9a-f]{1,4}:){6})(25[0-5]|2[0-4]\d|[0-1]?\d?\d)(\.(25[0-5]|2[0-4]\d|[0-1]?\d?\d)){3})\Z)|(\A(([0-9a-f]{1,4}:){5}[0-9a-f]{1,4}:(25[0-5]|2[0-4]\d|[0-1]?\d?\d)(\.(25[0-5]|2[0-4]\d|[0-1]?\d?\d)){3})\Z)|(\A([0-9a-f]{1,4}:){5}:[0-9a-f]{1,4}:(25[0-5]|2[0-4]\d|[0-1]?\d?\d)(\.(25[0-5]|2[0-4]\d|[0-1]?\d?\d)){3}\Z)|(\A([0-9a-f]{1,4}:){1,1}(:[0-9a-f]{1,4}){1,4}:(25[0-5]|2[0-4]\d|[0-1]?\d?\d)(\.(25[0-5]|2[0-4]\d|[0-1]?\d?\d)){3}\Z)|(\A([0-9a-f]{1,4}:){1,2}(:[0-9a-f]{1,4}){1,3}:(25[0-5]|2[0-4]\d|[0-1]?\d?\d)(\.(25[0-5]|2[0-4]\d|[0-1]?\d?\d)){3}\Z)|(\A([0-9a-f]{1,4}:){1,3}(:[0-9a-f]{1,4}){1,2}:(25[0-5]|2[0-4]\d|[0-1]?\d?\d)(\.(25[0-5]|2[0-4]\d|[0-1]?\d?\d)){3}\Z)|(\A([0-9a-f]{1,4}:){1,4}(:[0-9a-f]{1,4}){1,1}:(25[0-5]|2[0-4]\d|[0-1]?\d?\d)(\.(25[0-5]|2[0-4]\d|[0-1]?\d?\d)){3}\Z)|(\A(([0-9a-f]{1,4}:){1,5}|:):(25[0-5]|2[0-4]\d|[0-1]?\d?\d)(\.(25[0-5]|2[0-4]\d|[0-1]?\d?\d)){3}\Z)|(\A:(:[0-9a-f]{1,4}){1,5}:(25[0-5]|2[0-4]\d|[0-1]?\d?\d)(\.(25[0-5]|2[0-4]\d|[0-1]?\d?\d)){3}\Z) "; //strPattern = @"/^\s*((([0-9A-Fa-f]{1,4}:){7}([0-9A-Fa-f]{1,4}|:))|(([0-9A-Fa-f]{1,4}:){6}(:[0-9A-Fa-f]{1,4}|((25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)(\.(25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)){3})|:))|(([0-9A-Fa-f]{1,4}:){5}(((:[0-9A-Fa-f]{1,4}){1,2})|:((25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)(\.(25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)){3})|:))|(([0-9A-Fa-f]{1,4}:){4}(((:[0-9A-Fa-f]{1,4}){1,3})|((:[0-9A-Fa-f]{1,4})?:((25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)(\.(25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)){3}))|:))|(([0-9A-Fa-f]{1,4}:){3}(((:[0-9A-Fa-f]{1,4}){1,4})|((:[0-9A-Fa-f]{1,4}){0,2}:((25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)(\.(25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)){3}))|:))|(([0-9A-Fa-f]{1,4}:){2}(((:[0-9A-Fa-f]{1,4}){1,5})|((:[0-9A-Fa-f]{1,4}){0,3}:((25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)(\.(25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)){3}))|:))|(([0-9A-Fa-f]{1,4}:){1}(((:[0-9A-Fa-f]{1,4}){1,6})|((:[0-9A-Fa-f]{1,4}){0,4}:((25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)(\.(25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)){3}))|:))|(:(((:[0-9A-Fa-f]{1,4}){1,7})|((:[0-9A-Fa-f]{1,4}){0,5}:((25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)(\.(25[0-5]|2[0-4]\d|1\d\d|[1-9]?\d)){3}))|:)))(%.+)?\s*$/"; //strPattern = @"(:?[0-9a-fA-F]{1,4}:){7}([0-9a-fA-F]{1,4})\z"; //strPattern = @"\A((?:[0-9A-Fa-f]{1,4}(?::[0-9A-Fa-f]{1,4})*)?)::((?:[0-9A-Fa-f]{1,4}(?::[0-9A-Fa-f]{1,4})*)?)\z"; //strPattern = @"\A((?:[0-9A-Fa-f]{1,4}(?::[0-9A-Fa-f]{1,4})*)?)::((?:[0-9A-Fa-f]{1,4}:)*)(25[0-5]|2[0-4]\d|[0-1]?\d?\d)(\.(25[0-5]|2[0-4]\d|[0-1]?\d?\d)){3}\z"; //strPattern = @"/^(?:(?:(?:(?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){7})|(?:(?!(?:.*[a-f0-9](?::|$)){7,})(?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){0,5})?::(?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){0,5})?)))|(?:(?:(?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){5}:)|(?:(?!(?:.*[a-f0-9]:){5,})(?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){0,3})?::(?:[a-f0-9]{1,4}(?::[a-f0-9]{1,4}){0,3}:)?))?(?:(?:25[0-5])|(?:2[0-4][0-9])|(?:1[0-9]{2})|(?:[1-9]?[0-9]))(?:\.(?:(?:25[0-5])|(?:2[0-4][0-9])|(?:1[0-9]{2})|(?:[1-9]?[0-9]))){3}))$/i"; System.Text.RegularExpressions.Regex reValidationRule = new System.Text.RegularExpressions.Regex("^" + strPattern + "$"); if (reValidationRule.Match(strInputString).Success) // If matching pattern { System.Text.RegularExpressions.Match maResult = System.Text.RegularExpressions.Regex.Match(strInputString, strPattern); // Console.WriteLine(maResult.Groups.Count) string[] astrReturnValues = new string[4]; System.Text.RegularExpressions.GroupCollection gc = maResult.Groups; System.Text.RegularExpressions.CaptureCollection cc; int counter; //System.Web.Script.Serialization.JavaScriptSerializer jssJSONserializer = new System.Web.Script.Serialization.JavaScriptSerializer(); //Console.WriteLine(jssJSONserializer.Serialize()); // Loop through each group. for (int i = 0; i < gc.Count; i++) { Console.WriteLine("Group: {0}", i); cc = gc[i].Captures; counter = cc.Count; // Print number of captures in this group.

• Grid overlayed on image using javascript, need help getting grid coordinates.

  - by Alos

  Hi I am fairly new to javascript and could use some help, I am trying to overlay a grid on top of an image and then be able to have the user click on the grid and get the grid coordinate from the box that the user clicked.

Any help would be great. Thank you

• Creating a grid overlay over image.

  - by neteus

  Hi everybody, I made a script (using mootools library) that is supposed to overlay an image with a table grid and when each grid cell is clicked/dragged over its background color changes 'highlighting' the cell. Current code creates a table and positions it over the element (el, image in this case). Table was used since I am planning to add rectangle select tool later on, and it seemed easiest way to do it. <html> <head> <title></title> <script type="text/javascript" src="mootools.js"></script> <script type="text/javascript"> var SetGrid = function(el, sz, nr, nc){ //get number of rows/columns according to the 'grid' size numcols = el.getSize().x/sz; numrows = el.getSize().y/sz; //create table element for injecting cols/rows var gridTable = new Element('table', { 'id' : 'gridTable', 'styles' : { 'width' : el.getSize().x, 'height' : el.getSize().y, 'top' : el.getCoordinates().top, 'left' : el.getCoordinates().left } }); //inject rows/cols into gridTable for (row = 1; row<=numrows; row++){ thisRow = new Element('tr', { 'id' : row, 'class' : 'gridRow' }); for(col = 1; col<=numcols; col++){ thisCol = new Element('td', { 'id' : col, 'class' : 'gridCol0' }); //each cell gets down/up over event... down starts dragging|up stops|over draws area if down was fired thisCol.addEvents({ 'mousedown' : function(){ dragFlag = true; startRow = this.getParent().get('id'); startCol = this.get('id'); }, 'mouseup' : function(){ dragFlag = false; }, 'mouseover' : function(){ if (dragFlag==true){ this.set('class', 'gridCol'+$$('#lvlSelect .on').get('value')); } }, 'click' : function(){ //this.set('class', 'gridCol'+$$('#lvlSelect .on').get('id').substr(3, 1) ); str = $$('#lvlSelect .on').get('id'); alert(str.substr(2, 3)); } }); thisCol.inject(thisRow, 'bottom'); }; thisRow.inject(gridTable, 'bottom'); }; gridTable.inject(el.getParent()); } //sens level selector func var SetSensitivitySelector = function(el, sz, nr, nc){ $$('#lvlSelect ul li').each(function(el){ el.addEvents({ 'click' : function(){ $$('#lvlSelect ul li').set('class', ''); this.set('class', 'on'); }, 'mouseover' : function(){ el.setStyle('cursor','pointer'); }, 'mouseout' : function(){ el.setStyle('cursor',''); } }); }); } //execute window.addEvent('load', function(){ SetGrid($('imagetomap'), 32); SetSensitivitySelector(); }); </script> <style> #imagetomapdiv { float:left; display: block; } #gridTable { border:1px solid red; border-collapse:collapse; position:absolute; z-index:5; } #gridTable td { opacity:0.2; filter:alpha(opacity=20); } #gridTable .gridCol0 { border:1px solid gray; background-color: none; } #gridTable .gridCol1 { border:1px solid gray; background-color: green; } #gridTable .gridCol2 { border:1px solid gray; background-color: blue; } #gridTable .gridCol3 { border:1px solid gray; background-color: yellow; } #gridTable .gridCol4 { border:1px solid gray; background-color: orange; } #gridTable .gridCol5 { border:1px solid gray; background-color: red; } #lvlSelect ul {float: left; display:block; position:relative; margin-left: 20px; padding: 10px; } #lvlSelect ul li { width:40px; text-align:center; display:block; border:1px solid black; position:relative; padding: 10px; list-style:none; opacity:0.2; filter:alpha(opacity=20); } #lvlSelect ul li.on { opacity:1; filter:alpha(opacity=100); } #lvlSelect ul #li0 { background-color: none; } #lvlSelect ul #li1 { background-color: green; } #lvlSelect ul #li2 { background-color: blue; } #lvlSelect ul #li3 { background-color: yellow; } #lvlSelect ul #li4 { background-color: orange; } #lvlSelect ul #li5 { background-color: red; } </style> </head> <body> <div id="imagetomapdiv"> <img id="imagetomap" src="1.png"> </div> <div id="lvlSelect"> <ul> <li value="0" id="li0">0</li> <li value="1" id="li1">1</li> <li value="2" id="li2">2</li> <li value="3" id="li3">3</li> <li value="4" id="li4">4</li> <li value="5" id="li5" class="on">5</li> </ul> </div> </body> </html> A 'working' example: http://72.14.186.218/~alex/motion.php There are two problems: while it works just fine in FF, IE and Chrome do not create the table if the page is refreshed. If you go back to directory root and click on the link to the file the grid table is displayed, if you hit 'refresh' button -- the script runs but the table is not injected. Secondly, although the table HTML is injected in IE, it does not display it. I tried adding nbsp's to make sure its not ignored -- to no avail. Any suggestions on improving code or help with the issues is appreciated. Thanks!

• RemoteViewsService never gets called whenever we update app widget

  - by user3689160

  I am making one task widget application. This is a simple widget application which can be used to add new tasks by clicking on "+New Task". So ideally what I have done is, I've added a widget first, then when we click on "+New Task" a new activity opens up from where we can type in a new task and it should get updated in the ListView inside the home screen widget. Problem: Now whenever I add a new task, the ListView does not get updated. The data gets inside the database a new is created as well. My onUpdate(...) method gets called as well. There is a WidgetService.java which is a RemoteViewService that is being used to call the RemoteViewFactory but WidgetService.java gets called only when we create the widget, never after that. WidgetService.java never gets called again. I have the following setup MyWidgetProvider.java AppWidgetProvider class for updating the widget and filling its remote views. public class MyWidgetProvider extends AppWidgetProvider { public static int randomNumber=132; static RemoteViews remoteViews = null; @Override public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { updateList(context,appWidgetManager,appWidgetIds); } public static void updateList(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds){ final int N = appWidgetIds.length; Log.d("MyWidgetProvider", "length="+appWidgetIds.length+""); for (int i = 0; i<N; ++i) { Log.d("MyWidgetProvider", "value"+ i + "="+appWidgetIds[i]); // Calling updateWidgetListView(context, appWidgetIds[i]); to load the listview with data remoteViews = updateWidgetListView(context, appWidgetIds[i]); // Updating the Widget with the new data filled remoteviews appWidgetManager.updateAppWidget(appWidgetIds[i], remoteViews); appWidgetManager.notifyAppWidgetViewDataChanged(appWidgetIds[i], R.id.lv_tasks); } } private static RemoteViews updateWidgetListView(Context context, int appWidgetId) { Intent svcIntent = null; remoteViews = new RemoteViews(context.getPackageName(),R.layout.widget_demo); //RemoteViews Service needed to provide adapter for ListView svcIntent = new Intent(context, WidgetService.class); //passing app widget id to that RemoteViews Service svcIntent.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, appWidgetId); //setting a unique Uri to the intent //binding the data from the WidgetService to the svcIntent svcIntent.setData(Uri.parse(svcIntent.toUri(Intent.URI_INTENT_SCHEME))); //setting adapter to listview of the widget remoteViews.setRemoteAdapter(R.id.lv_tasks, svcIntent); //setting click listner on the "New Task" (TextView) of the widget remoteViews.setOnClickPendingIntent(R.id.tv_add_task, buildButtonPendingIntent(context)); return remoteViews; } // Just to create PendingIntent, this will be broadcasted everytime textview containing "New Task" is clicked and OnReceive method of MyWidgetIntentReceiver.java will run public static PendingIntent buildButtonPendingIntent(Context context) { Intent intent = new Intent();

Please help me out with this problem. I am seen all the posts here and on other websites no body is having any solution. But I am sure a solution exist to this. Thanks for your help!

The <hr/> is at the top somewhere, but I'm not sure where. <?php print "<?xml version=\"1.0\" encoding=\"UTF-8\"?>"; ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <font face="Segoe UI"> <body> <script type="text/javascript"> /*function detectBrowser() { var browser = navigator.appCodeName; if (browser!="Mozilla") {document.location.href="noaccess.php"; alert(browser);} } detectBrowser(); */ </script> <title>Second</title> <link rel="stylesheet" type="text/css" href="allCSS.css"/> <center> <!--<img align="right" src="logo.png" id="headerimg"/>--> <input type="image" id="headerimg" src="logo.png" align="right" onclick="toggleh();"/> <ul align="center" class=""> <div class="menu"> <ul class="nav"> <li><strong><a href="index.php">Home</a></strong> <ul> <li><a href="games.php">Games</a></li> <li><a href="browse.php">Browse</a></li> <li><a href="catalogue.php">Catalogue</a></li> <li><a href="forum.php">Forums</a></li> </ul> </li> <li><strong><a href="games">Games</a></strong> <ul> <li><a href="profile.php">Profile</a></li> <li><a href="settings.php">Settings</a></li> </ul> </li> <li><strong><a href="contact">Contact</a></strong> <ul> <li><a href="contact/index.php">Phone</a></li> <li><a href="contact/index.php">Email</a></li> <li><a href="contact/index.php">Mail</a></li> </ul> </li> </div> </center> </body> <center> <?php echo '<div id="msg">'; include 'message.txt'; echo '</div>'; //include 'hits.txt'; ?> <p> <?php function ChangeText($txt) { $txt='<script type="text/javascript">get();</script>'; echo '<script type="text/javascript">change();</script>'; $filename="message.txt"; $fp=fopen($filename,'w'); fwrite($fp,'<h4 class="hmsg">' . $txt .
