  • Slide div inside another div effect

    - by mariki
    I am trying to create sliding images effect: Online demolink text. The problem is when you click rapidly and randomly on the buttons and not wait for animation to finish causing unpredicted results and even stopping the functionality to work. (and once it stopped in the middle of 2 images...) How Can I make it work without bugs? I know that there are some other tools for that sliding like jquery and other approaches like changing the position attribute and not the scrollLeft attribute. But I want to do it as it is, with scrollLeft, if it possible of course. The Code: <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <title>Untitled Document</title> <style type="text/css"> body { padding:0px; margin:0px; } #imageContainer { width: 500px; position: relative; } #div { overflow: hidden; white-space: nowrap; } #div img { cursor: pointer; vertical-align: bottom; width: 500px; padding:0px; margin:0px; display:inline; } </style> <script type="text/javascript"> var scrollIntervalID; var currentIndex=0; function Scroll(ind){ var dir = ind ==currentIndex?0:ind<currentIndex?-1:1; var steps = Math.abs(ind-currentIndex); scrollIntervalID = setInterval(function(){ var i=(steps*10)-1; return function(){ if (i <= 0) clearInterval(scrollIntervalID); var elm = document.getElementById("div"); elm.scrollLeft +=dir * 50; i--; document.getElementById("span").innerHTML=elm.scrollLeft; } }(), 15); currentIndex=ind; } </script> </head> <body> <div id="imageContainer"> <div id="div"> <img id="image1" src="Images/pic1.jpg" width="500px"/><img id="image2" src="Images/pic2.jpg" width="500px"/><img id="image3" src="Images/pic3.jpg" width="500px"/><img id="image4" src="Images/pic4.jpg" width="500px"/> </div> </div> <div> <input type="button" value="1" onclick="Scroll(0);"/> <input type="button" value="2" onclick="Scroll(1);"/> <input type="button" value="3" onclick="Scroll(2);"/> <input type="button" value="4" onclick="Scroll(3);"/> </div> <span id="span"></span> </body> </html>

  • jQuery .live fireing multiple times!

    - by cstrzelc
    Greetings Guru's, This is a little hard to explain, but I'll give it a shot. I have a quick question regarding to the .live() function in JQuery. I'm going to simplify the example here. I have a page "index.php" that has a container "#display_files_container" which is populated with anchor links that are generated dynamically by a different page "process.php". The links are loaded into that same <div> when those links are selected based on the attributes of that link. See Examples: INDEX.PHP <html> <head><title>index.php</title> <!-- this function below loads process.php and passes it the dirid variable via post. I then use this post variable inside of process.php to pull other links from the database --> <script language="text/javascript"> $('.directory').live("click", function() { $('#display_files_container').load('plugins/project_files/process.php', {dirid: $(this).attr('dirid')}); }); </script> </head> <?php /*This code initial populates the link array so we have the first links populated before the users clicks for the first time*/ some code to fetch the $current_directory_list array from the database initially.... >? <body> <div id='display_files_container'> <?php /*Cycle through the array and echo out all the links which have been pulled from DB*/ for($i=0;$i<$current_directory_count;$i++) { echo "<a href='#' class='directory' dirid='".$current_directory_list[$i]['id']." '>".$current_directory_list[$i]['directory_name']. "</a> "; } ?> </div> </body> </html> PROCESS.PHP this file includes code to populate the $current_directory_list[] array from the database based on the post variable "$_POST['dirid']" that was sent from the .click() method in index.php. It then echo's the results out and we display them in the #display_files_container container. When you click on those links the process repeats. This works..... you can click though the directory tree and it loads the new links every time. However, it seems to want to .load() the process.php file many times over for one click. The number of times process.php is loaded seems to increase the more the links are clicked. So for example you can click on a link and firebug reports that process.php was loaded 23 times..... Eventually I would imagine I would record a stackoverflow. Please let me know if you have any ideas. Are there any ways that I can assure that .live() loads the process.php file only once? Thanks, -cs

  • Unknown error sourcing a script containing 'typeset -r' wrapped in command substitution

    - by Bernard Assaf
    I wish to source a script, print the value of a variable this script defines, and then have this value be assigned to a variable on the command line with command substitution wrapping the source/print commands. This works on ksh88 but not on ksh93 and I am wondering why. $ cat typeset_err.ksh #!/bin/ksh unset _typeset_var typeset -i -r _typeset_var=1 DIR=init # this is the variable I want to print When run on ksh88 (in this case, an AIX 6.1 box), the output is as follows: $ A=$(. ./typeset_err.ksh; print $DIR) $ echo $A init When run on ksh93 (in this case, a Linux machine), the output is as follows: $ A=$(. ./typeset_err.ksh; print $DIR) -ksh: _typeset_var: is read only $ print $A ($A is undefined) The above is just an example script. The actual thing I wish to accomplish is to source a script that sets values to many variables, so that I can print just one of its values, e.g. $DIR, and have $A equal that value. I do not know in advance the value of $DIR, but I need to copy files to $DIR during execution of a different batch script. Therefore the idea I had was to source the script in order to define its variables, print the one I wanted, then have that print's output be assigned to another variable via $(...) syntax. Admittedly a bit of a hack, but I don't want to source the entire sub-script in the batch script's environment because I only need one of its variables. The typeset -r code in the beginning is the error. The script I'm sourcing contains this in order to provide a semaphore of sorts--to prevent the script from being sourced more than once in the environment. (There is an if statement in the real script that checks for _typeset_var = 1, and exits if it is already set.) So I know I can take this out and get $DIR to print fine, but the constraints of the problem include keeping the typeset -i -r. In the example script I put an unset in first, to ensure _typeset_var isn't already defined. By the way I do know that it is not possible to unset a typeset -r variable, according to ksh93's man page for ksh. There are ways to code around this error. The favorite now is to not use typeset, but just set the semaphore without typeset (e.g. _typeset_var=1), but the error with the code as-is remains as a curiosity to me, and I want to see if anyone can explain why this is happening. By the way, another idea I abandoned was to grep the variable I need out of its containing script, then print that one variable for $A to be set to; however, the variable ($DIR in the example above) might be set to another variable's value (e.g. DIR=$dom/init), and that other variable might be defined earlier in the script; therefore, I need to source the entire script to make sure I all variables are defined so that $DIR is correctly defined when sourcing.

  • How to schedule dynamic function with cron job?

    - by iBrazilian2
    I want to know how I can schedule a dynamic(auto populated data) function to auto run everyday at saved time? Let's say I have a form that once the button is clicked it sends the data to the function, which the posts the data. I simply want to automate that so that I don't have to press the button. <ul> <?php foreach($Class->retrieveData as $data) { <form method="post" action=""> <li> <input type="hidden" name="name">'.$data['name'].'<br/> <input type="hidden" name="description">'.$data['description'].'<br/> <input type="submit" name="post_data" value="Post"> </li> </form> } ?> </ul> Now, the form will pass the data to the function. if(isset($_POST['post_data'])) // if post_data button is clicked then it runs myFunction() { myFunction(); } myFunction() { $name = $_POST['name']; $description = $_POST['description']; } I tried doing the following but the problem is that Cron Job can only run the whole .php file, and I am retrieving the saved time to run from MySQL. foreach($Class->getTime() as $timeData) { $timeHour = $timeData['timeHour']; $timeMinute = $timeData['timeMinute']; $hourMin = date('H:i'); $timeData = ''.$timeHour.':'.$timeMinute.''; if($hourMin == $timeData) { run myFunction. } } $hourMin is the current hour:minute which is being matched against a saved time to auto run from Mysql. So if $hourMin == $timeData then the function will run. How can I run Cron Job to auto run myFunction() if the $hourMin equals $timeData? So... List 1 = is to be runned at 10am List 2 = is to be runned at 12pm List 3 = is to be runned at 2pm The 10am, 12pm, 2pm is the $timeHour and $timeMinute that is retrieved from MySQL but based on each list id's. EDIT @randomSeed, 1) I can schedule cron jobs. 2) $name and $description will all be arrays, so the following is what I am trying to accomplish. $name = array( 'Jon', 'Steven', 'Carter' ); $description = array( 'Jon is a great person.', 'Steven has an outgoing character.', 'Carter is a horrible person.' ); I want to parse the first arrays from both $name and $description if the scheduled time is correct. In database I have the following postDataTime table +----+---------+----------+------------+--------+ | iD | timeDay | timeHour | timeMinute | postiD | +--------------------------------------+--------+ | 1 | * | 9 | 0 | 21 | |----|---------|----------|------------|--------| | 2 | * | 10 | 30 | 22 | |----|---------|----------|------------|--------| | 3 | * | 11 | 0 | 23 | +----|---------+----------+------------+--------+ iD = auto incremented on upload. timeDay = * is everyday (cron job style) timeHour = Hour of the day to run the script timeMinute = minute of the hour to run script postiD = this is the id of the post that is located in another table (n+1 relationship) If it's difficult to understand.. if(time() == 10:30(time from MySQL postiD = 22)) { // run myFunction with the data that is retrieved for that time ex: $postiD = '22'; $name = 'Steven'; $description = 'Steven has an outgoing character.'; // the above is what will be in the $_POST from the form and will be // sent to the myFunction() } I simply want to schedule everything according to the time that is saved to MySQL as I showed at the very top(postDataTime table). (I'd show what I have tried, but I have searched for countless hours for an example of what I am trying to accomplish but I cannot find anything and what I tried doesn't work.). I thought I could use the exec() function but from what it seems that does not allow me to run functions, otherwise I would do the following.. $time = '10:30'; if($time == time()) { exec(myFunction()); }

  • Java Applet Deployment, ClassNotFoundException (primary class)

    - by Matt
    This is driving me up the wall. I have checked and rechecked spelling and paths. I have tried just about every combination of paths, including relative, absolute, and full http paths. I continue to get the following error when trying to load a Java applet: java.lang.ClassNotFoundException: AppletClient.class at sun.plugin2.applet.Applet2ClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.plugin2.applet.Plugin2ClassLoader.loadCode(Unknown Source) at sun.plugin2.applet.Plugin2Manager.createApplet(Unknown Source) at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Exception: java.lang.ClassNotFoundException: AppletClient.class The HTML used to load the applet: <applet width="100" height="100" archive="applet/myapplet.jar, applet/applet_dependency.jar" code="AppletClient.class"> <param value="blahblah" name="username"> <param value="false" name="codebase_lookup"> </applet> The applet is in a relative directory, "applet", from the path of the current page. I have unzipped the jar file and can see AppletClient.class. Also, in the source of the project, it is spelled that way (casing and all). I have tried with/without the parameters. I have changed the names of the archive jars in the applet include tag just to see if I get a different error for bad file names (same error). I have manually done GETs on the jars to make sure the server is responding to the requests (it is). I have tried with and without the codebase tag, with all different varieties of paths (start getting bad "magic number" errors on those). I know that this error sometimes pops up when a dependency fails to load, so it can be misleading, but all dependencies are present, accounted for, and are fetchable via manual GETs. Between each and every attempt I always clear my cache in FireFox. These problems are reproduced in IE8 and Chrome as well. Per my Java Console from the browser, I am running Java Plug-in 1.6.0_20. This is from the same machine that I develop the applet on, which runs fine via Eclipse. Finally, I kicked on Fiddler2, and I don't see a single request for the jar files anywhere The host site is running from my Visual Studio debugger, so it's running on localhost. But I see the requests for all the other resources on Fiddler. Just... no Jars. ANYWHERE. I clear the log, cleared my browser cache, and did a ctrl-R refresh. And still, not a single Jar request on the Fiddler log. I even did a delayed write (with JS) of the applet tag after the page loaded, once all the Fiddler activity slowed down. The element gets written to the document (and I can see the 100x100 Java error window), but not a single request shows up on Fiddler. Any suggestions, before I go crawl into the corner and cry myself to sleep? EDIT: From the Java console, if I hit "l" (el) to "dump classloader list", I see something that looks like this: Live entry: key=http://localhost:55446/BaseWebSite/,http://localhost:55446/BaseWebSite/applet/myappliet.jar, http://localhost:55446/BaseWebSite/applet/applet_dependency.jar, refCount=1, threadGroup=sun.plugin2.applet.Applet2ThreadGroup[name=http://localhost:55446/BaseWebSite/-threadGroup,maxpri=4]

  • Hardware/Software inventory open source projects

    - by Dick dastardly
    Dear Stackoverflowers I would like to develop a Network Inventory application that works on any operating system. Reports on every possible resource attacehd to a network. Reports all pertinent details of hardware and software. Thats (and i hate to use the phrase) my "End Game". However I am running before i can crawl here. I have no experience of this type of development, e.g. discovering a computers hardware and software settings. I've spent almost two weeks googling and come up short! :-(. So I am turning to you to ask these questions:- My first step is to find an existing open source project i can incorporate into my own code that extracts the fine grained details i am after, e.g. EVERYTHING there is to know about the hardaware and software on a single machine. Does this project exist? or do i have to develop that first? Have i got to write all this in C? I am guessing getting this information about a computer is going to be easier than for printers, scanners, routers etc... e.g. everything else you would find attached to a network. Once i have access to a single computers details i then need to investigate how i can traverse an entire newtork of printers, scanners, routers, load balancers, switches, firewalls, workstations, servers, storeage devices, laptops, monitors, the list goes on and on One problem i have is i dont have a 1000 machine newtork to play on! Is there any such resource available on theinternet? (is that a silly question?) Anywho, if you dont ask you wont find out! One aspect iam really looking forward to finding out how to travers the entire network, should i be using TCP/IP for this? Whats a good site, blog, usergorup, book for TCP/IP development? How do i go about getting through firewalls? How many questions can i ask in one go? :-) My previous question on this topic ended up with PYTHON being championed as the language/script to go with to develop this application in. Having looked at a few PYTHON examples they all seemed to be related to WINDOWS networks and interrogating Windows Management Instrumentation (WMI). I had the feeling you cant rely on whats in WMI, and even if you can that s no good for UNIX netwrks. Surely there exist common code for extracting hardware and software details from a computer? Why cant i find it on the internet? Pease help? Theres no prizes though :-( Thanks in advance I would like to appologise if i have broken forum rules or not tried hard enough on my own before asking for assistance. I just would like to start moving forward with this as its one of the best projects i have been involved with. I am inspired by the many differnt number of challenges involved and that if i manage to produce a useful application at the end of it it would hopefully be extremely helpful to many people. That sit Thanks in advance DD

  • C# Asynchronous Network IO and OutOfMemoryException

    - by The.Anti.9
    I'm working on a client/server application in C#, and I need to get Asynchronous sockets working so I can handle multiple connections at once. Technically it works the way it is now, but I get an OutOfMemoryException after about 3 minutes of running. MSDN says to use a WaitHandler to do WaitOne() after the socket.BeginAccept(), but it doesn't actually let me do that. When I try to do that in the code it says WaitHandler is an abstract class or interface, and I can't instantiate it. I thought maybe Id try a static reference, but it doesnt have teh WaitOne() method, just WaitAll() and WaitAny(). The main problem is that in the docs it doesn't give a full code snippet, so you can't actually see what their "wait handler" is coming from. its just a variable called allDone, which also has a Reset() method in the snippet, which a waithandler doesn't have. After digging around in their docs, I found some related thing about an AutoResetEvent in the Threading namespace. It has a WaitOne() and a Reset() method. So I tried that around the while(true) { ... socket.BeginAccept( ... ); ... }. Unfortunately this makes it only take one connection at a time. So I'm not really sure where to go. Here's my code: class ServerRunner { private Byte[] data = new Byte[2048]; private int size = 2048; private Socket server; static AutoResetEvent allDone = new AutoResetEvent(false); public ServerRunner() { server = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); IPEndPoint iep = new IPEndPoint(IPAddress.Any, 33333); server.Bind(iep); Console.WriteLine("Server initialized.."); } public void Run() { server.Listen(100); Console.WriteLine("Listening..."); while (true) { //allDone.Reset(); server.BeginAccept(new AsyncCallback(AcceptCon), server); //allDone.WaitOne(); } } void AcceptCon(IAsyncResult iar) { Socket oldserver = (Socket)iar.AsyncState; Socket client = oldserver.EndAccept(iar); Console.WriteLine(client.RemoteEndPoint.ToString() + " connected"); byte[] message = Encoding.ASCII.GetBytes("Welcome"); client.BeginSend(message, 0, message.Length, SocketFlags.None, new AsyncCallback(SendData), client); } void SendData(IAsyncResult iar) { Socket client = (Socket)iar.AsyncState; int sent = client.EndSend(iar); client.BeginReceive(data, 0, size, SocketFlags.None, new AsyncCallback(ReceiveData), client); } void ReceiveData(IAsyncResult iar) { Socket client = (Socket)iar.AsyncState; int recv = client.EndReceive(iar); if (recv == 0) { client.Close(); server.BeginAccept(new AsyncCallback(AcceptCon), server); return; } string receivedData = Encoding.ASCII.GetString(data, 0, recv); //process received data here byte[] message2 = Encoding.ASCII.GetBytes("reply"); client.BeginSend(message2, 0, message2.Length, SocketFlags.None, new AsyncCallback(SendData), client); } }

  • "Could not establish secure channel for SSL/TLS" in .NET CF application on smart phone

    - by Stefan Mohr
    I have a stubborn communications issue with an application running on the .NET Compact Framework 3.5 on Windows Mobile smartphones. I am constructing a web request using this code: UTF8Encoding encoding = new System.Text.UTF8Encoding(); byte[] Data = encoding.GetBytes(HttpUtility.ConstructQueryString(parameters)); httpRequest = WebRequest.Create((domain)) as HttpWebRequest; httpRequest.Timeout = 10000000; httpRequest.ReadWriteTimeout = 10000000; httpRequest.Credentials = CredentialCache.DefaultCredentials; httpRequest.Method = "POST"; httpRequest.ContentType = "application/x-www-form-urlencoded"; httpRequest.ContentLength = Data.Length; Stream SendReq = httpRequest.GetRequestStream(); SendReq.Write(Data, 0, Data.Length); SendReq.Close(); HttpWebResponse httpResponse = (HttpWebResponse)httpRequest.GetResponse(); return httpResponse.GetResponseStream(); The web service functions by receiving a JSON-encoded document as part of the URL (eg. https://site.com/ws/sync??document={"version":"1.0.0","items":[{"item_1":"item1"}]}&user=usr&password=pw), and as a response receives another JSON document as response data. This code runs fine on all emulators and PDAs running WM 5 and 6. We have seen an issue with a couple of customers running Treo smartphones (and only on the Sprint network). We have tested the code on an identical device on the AT&T network (via DeviceAnywhere) and once again the code worked as we expected. This has to be some sort of security policy on the phone, but we've been unable to determine a workaround or diagnose it thoroughly as we cannot reproduce it in house and have had to resort to getting users to assist with running test drivers for us. When this code executes, the user's device throws the following exception: System.Net.WebException Could not establish secure channel for SSL/TLS Stack trace: at System.Net.HttpWebRequest.finishGetRequestStream() at System.Net.HttpWebRequest.GetRequestStream() at OurApp.GetResponseStream(String domain, Hashtable parameters) inner exception: System.IO.IOException Authentication failed because the remote party has closed the transport stream. Stack trace: at System.Net.SslConnectionState.ClientSideHandshake() at System.Net.SslConnectionState.PerformClientHandShake() at System.Net.Connection.connect(Object ignored) at System.Threading.ThreadPool.WorkItem.doWork(Object o) at System.Threading.Timer.ring() Examining the server Apache logs shows no hits from the user's IP - I don't think the device is even attempting to send a packet before failing. If relevant, the server is running Apache on Linux and is written using the TurboGears Python framework. The server certificate is issued by a CA and is still valid. The test driver where this error was copied from was not code signed, however the same error (without the error messages) is signed with a GeoTrust certificate so we don't believe this is a code signing issue. The application installs and launches without issue on all phones - it's just establishing this SSL connection that is breaking for these users. One significant issue in troubleshooting is that there is a substantial inconvenience each time we try out a solution (need to find a "volunteer" customer), so we're really looking for a silver bullet or a better understanding of the handshaking process so we can be reasonably confident we only need to ask the user to test it one or two more times. One final mention: we have tried the sync both over ActiveSync and also over GPRS with identical results. Any thoughts would be greatly appreciated!

  • Accessing a vector<vector<int>> as a flat array

    - by user1762276
    For this array: vector<vector<int> > v; v.push_back(vector<int>(0)); v.back().push_back(1); v.back().push_back(2); v.back().push_back(3); v.back().push_back(4); I can output {1, 2, 3, 4} easily enough: cout << v[0][0] << endl; cout << v[0][1] << endl; cout << v[0][2] << endl; cout << v[0][3] << endl; To access it as a flat array I can do this: int* z = (int*)&v[0].front(); cout << z[0] << endl; cout << z[1] << endl; cout << z[2] << endl; cout << z[3] << endl; Now, how do I access the multidimensional vector as a flat multidimensional array? I cannot use the same format as accessing a single-dimensional vector: // This does not work (outputs garbage) int** n = (int**)&v.front(); cout << n[0][0] << endl; cout << n[0][1] << endl; cout << n[0][2] << endl; cout << n[0][3] << endl; The workaround I've found is to do this: int** n = new int* [v.size()]; for (size_t i = 0; i < v.size(); i++) { n[i] = &v.at(i).front(); } cout << n[0][0] << endl; cout << n[0][1] << endl; cout << n[0][2] << endl; cout << n[0][3] << endl; Is there a way to access the entire multidimensional vector like a flat c-style array without having to dynamically allocate each dimension above the data before accessing it? Speed is not critical in the implementation and clarity for maintenance is paramount. A multidimensional vector is just fine for storing the data. However, I want to also expose the data as a flat c-style array in the SDK so that it can be easily accessible by other languages. This means that exposing the vectors as an STL object is a no go. The solution I came up with works fine for my needs as I only evaluate the array once at the very end of processing to "flatten" it. However, is there a better way to go about this? Or am I already doing it the best way I possibly can without re-implementing my own data structure (overkill since my flatten code is only a few lines). Thank you for your advice, friends!

  • Detecting Acceleration in a car (iPhone Accelerometer)

    - by TheGazzardian
    Hello, I am working on an iPhone app where we are trying to calculate the acceleration of a moving car. Similar apps have accomplished this (Dynolicious), but the difference is that this app is designed to be used during general city driving, not on a drag strip. This leads us to one big concern that Dynolicious was luckily able to avoid: hills. Yes, hills. There are two important stages to this: calibration, and actual driving. Our initial run was simple and suffered the consequences. During the calibration stage, I took the average force on the phone, and during running, I just subtracted the average force from the current force to get the current acceleration this frame. The problem with this is that the typical car receives much more force than just the forward force - everything from turning to potholes was causing the values to go out of sync with what was really happening. The next run was to add the condition that the iPhone must be oriented in such a way that the screen was facing toward the back of the car. Using this method, I attempted to follow only force on the z-axis, but this obviously lead to problems unless the iPhone was oriented directly upright, because of gravity. Some trigonometry later, and I had managed to work gravity out of the equation, so that the car was actually being read very, very well by the iPhone. Until I hit a slope. As soon as the angle of the car changed, suddenly I was receiving accelerations and decelerations that didn't make sense, and we were once again going out of sync. Talking with someone a lot smarter than me at math lead to a solution that I have been trying to implement for longer than I would like to admit. It's steps are as follows: 1) During calibration, measure gravity as a vector instead of a size. Store that vector. 2) When the car initially moves forward, take the vector of motion and subtract gravity. Use this as the forward momentum. (Ignore, for now, the user cases where this will be difficult and let's concentrate on the math :) 3) From the forward vector and the gravity vector, construct a plane. 4) Whenever a force is received, project it onto said plane to get rid of sideways force/etc. 5) Then, use that force, the known magnitude of gravity, and the known direction of forward motion to essentially solve a triangle to get the forward vector. The problem that is causing the most difficulty in this new system is not step 5, which I have gotten to the point where all the numbers look as they should. The difficult part is actually the detection of the forward vector. I am selecting vectors whose magnitude exceeds gravity, and from there, averaging them and subtracting gravity. (I am doing some error checking to make sure that I am not using a force just because the iPhone accelerometer was off by a bit, which happens more frequently than I would like). But if I plot these vectors that I am using, they actually vary by an angle of about 20-30 degrees, which can lead to some strong inaccuracies. The end result is that the app is even more inaccurate now than before. So basically - all you math and iPhone brains out there - any glaring errors? Any potentially better solutions? Any experience that could be useful at all? Award: offering a bounty of $250 to the first answer that leads to a solution.

  • Checkbox values to varchar via Spring

    - by iowatiger08
    I am trying to get a varchar message from a database to display the selected values of a checkbox field in a jsp for patient's medication's dosage frequency. The possible values will be saved in comma-delimited string in the varchar. For most form fields there is simply a one form value to one database field ratio, but in this case, I am needing to merge the values that would come as a string[] into the comma-delimited string and then when retrieving that record for that medication of that patient, display the selected values from the comma-delimited string as selected from the selectableDosageFrequencyList. You assistance in this is greatly appreciated as I am not sure what I am missing here. In the application context, I created the list of possible values as part of the ServiceBean. <property name="selectableDosageFrequencyList"> <set> <value>On an empty stomach</value> <value>Every other day</value> <value>4 times daily</value> <value>3 times daily</value> <value>Twice daily</value> <value>At bedtime</value> <value>With meal</value> <value>As needed</value> <value>Once daily</value> </set> </property> This is set up in the flow as requestscope. <view-state id="addEditMedication" model="medication"> <on-render> <set name="requestScope.selectableDosageFrequencyList" value="memberService.buildSelectableDosageFrequencyList(patient)" /> </on-render> ... <transition on="next" to="assessment" > <evaluate expression="memberService.updateMedication(patient, medication)" /> </transition> </view-state> I have helper methods in the memberService that need to be executed when the form is init and then when the form is completed. //get the form fields selected and build the new string for db public String setSelectedDosageFrequency(String [] dosageFrequencies){ String frequencies = null; if (dosageFrequencies != null){ for (String s : dosageFrequencies){ frequencies = frequencies + "," + s; } } return frequencies; } //get value from database and build selected Set public LinkedHashSet<String> getSelectedDosageFrequencyList(String dosageFrequency){ String copyOfDosages =dosageFrequency;//may not need to do this LinkedHashSet<String> setofSelectedDosageFrequency = new LinkedHashSet<String> (); while (copyOfDosages!= null && copyOfDosages.length()>0){ for (String aFrequency: selectableDosageFrequencyList){ if (copyOfDosages.contains(aFrequency)){ setofSelectedDosageFrequency.add(aFrequency); if (!copyOfDosages.equals(aFrequency) && copyOfDosages.endsWith(aFrequency)){ copyOfDosages.replaceAll(","+aFrequency, ""); }else if (!copyOfDosages.equals(aFrequency) && copyOfDosages.contains(aFrequency=",")){ copyOfDosages.replaceAll(aFrequency+",", ""); }else copyOfDosages.replaceAll(aFrequency, ""); copyOfDosages.trim(); } } } return setofSelectedDosageFrequency; } The Medication class that backs the form will have a variable for dosage-frequency as a string. private String dosageFrequency; The jsp I currently am doing this. <div class="formField"> <form:label path="dosageFrequency">Dosage Frequency</form:label> <ul class="multi-column double" style="width: 550px;"> <form:checkboxes path="dosageFrequency" items="${selectableDosageFrequencyList}" itemLabel="${selectableDosageFrequencyList}" element="li" /> </ul> </div>

  • Difference between SQL 2005 and SQL 2008 for inserting multiple rows with XML

    - by Sam Dahan
    I am using the following SQL code for inserting multiple rows of data in a table. The data is passed to the stored procedure using an XML variable : INSERT INTO MyTable SELECT SampleTime = T.Item.value('SampleTime[1]', 'datetime'), Volume1 = T.Item.value('Volume1[1]', 'float'), Volume2 = T.Item.value('Volume2[1]', 'float') FROM @xml.nodes('//Root/MyRecord') T(item) I have a whole bunch of unit tests to verify that I am inserting the right information, the right number of records, etc.. when I call the stored procedure. All fine and dandy - that is, until we began to monkey around with the compatibility level of the database. The code above worked beautifully as long as we kept the compatibility level of the DB at 90 (SQL 2005). When we set the compatibility level at 100 (SQL 2008), the unit tests failed, because the stored procedure using the code above times out. The unit tests are dropping the database, re-creating it from scripts, and running the tests on the brand new DB, so it's not - I think - a question of the 'old compatibility level' sticking around. Using the SQL Management studio, I made up a quick test SQL script. Using the same XML chunk, I alter the DB compat level , truncate the table, then use the code above to insert 650 rows. When the level is 90 (SQL 2005), it runs in milliseconds. When the level is 100 (SQL 2008) it sometimes takes over a minute, sometimes runs in milliseconds. I'd appreciate any insight anyone might have into that. EDIT The script takes over a minute to run with my actual data, which has more rows than I show here, is a real table, and has an index. With the following example code, the difference goes between milliseconds and around 5 seconds. --use [master] --ALTER DATABASE MyDB SET compatibility_level =100 use [MyDB] declare @xml xml set @xml = '<?xml version="1.0"?> <Root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Record> <SampleTime>2009-01-24T00:00:00</SampleTime> <Volume1>0</Volume1> <Volume2>0</Volume2> </Record> ..... 653 records, sample time spaced out 4 hours ........ </Root>' DECLARE @myTable TABLE( ID int IDENTITY(1,1) NOT NULL, [SampleTime] [datetime] NOT NULL, [Volume1] [float] NULL, [Volume2] [float] NULL) INSERT INTO @myTable select T.Item.value('SampleTime[1]', 'datetime') as SampleTime, Volume1 = T.Item.value('Volume1[1]', 'float'), Volume2 = T.Item.value('Volume2[1]', 'float') FROM @xml.nodes('//Root/Record') T(item) I uncomment the 2 lines at the top, select them and run just that (the ALTER DATABASE statement), then comment the 2 lines, deselect any text and run the whole thing. When I change from 90 to 100, it runs all the time in 5 seconds (I change the level once, but I run the series several times to see if I have consistent results). When I change from 100 to 90, it runs in milliseconds all the time. Just so you can play with it too. I am using SQL Server 2008 R2 standard edition.

  • WPF BackgroundWorker Execution

    - by Sanju
    Hi All, I've been programming C# for a while now (I'm a Computer Science major), and have never had to implement threading. I am currently building an application for a client that requires threading for a series of operations. Due to the nature of the client/provider agreement, I cannot release the source I am working with. The code that I have posted is in a general form. Pretty much the basic idea of what I am implementing, excluding the content specific source. The first Snippet demonstrates my basic structure, The Progress class is a custom progress window that is displayed as a dialog to prevent user UI interaction. I am currently using the code to complete database calls based on a collection of objects in another area of the application code. For example, I have a collection of "Objects" of one of my custom classes, that I perform these database calls on or on behalf of. My current set up works just fine when I call the "GeneralizedFunction" one and only one time. What I need to do is call this function once for every object in the collection. I was attempting to use a foreach loop to iterate through the collection, then I tried a for loop. For both loops, the result was the same. The Async operation performs exactly as desired for the first item in the collection. This, however, is the only one it works for. For each subsequent item, the progress box (my custom window) displays and immediately closes. In terms of the database calls, the calls for the first item in the collection are the only ones that successfully complete. All others aren't attempted. I've tried everything that I know and don't know to do, but I just cannot seem to get it to work. How can I get this to work for my entire collection? Any and all help is very greatly appreciated. Progress progress; BackgroundWorker worker; // Cancel the current process private void CancelProcess(object sender, EventArgs e) { worker.CancelAsync(); } // The main process ... "Generalized" private void GeneralizedFunction() { progress = new Progress(); progress.Cancel += CancelProcess; progress.Owner = this; Dispatcher pDispatcher = progress.Dispatcher; worker = new BackgroundWorker(); worker.WorkerSupportsCancellation = true; object[] workArgs = { arg1, arg2, arg3}; worker.DoWork += delegate(object s, DoWorkEventArgs args) { /* All main logic here */ foreach(Class ClassObject in ClassObjectCollection) { //Some more logic here UpdateProgressDelegate update = new UpdateProgressDelegate(updateProgress); pDispatcher.BeginInvoke(update, arg1,arg2,arg3); Thread.Sleep(1000); } }; worker.RunWorkerCompleted += delegate(object s, RunWorkerCompletedEventArgs args) { progress.Close(); }; worker.RunWorkerAsync(workArgs); progress.ShowDialog(); } public delegate void UpdateProgressDelegate(arg1,arg2,arg3); private void updateProgress(arg1,arg2,arg3) { //Update progress }

  • I'm looking for an online ASP.NET tutor.

    - by pkiyan
    $15/hr. I know it's not much but... Hi. I'm looking for an ASP.NET tutor. I want to use a remote desktop application so we can see each others screens and use Skype or phone to communicate with. You won't need to come up with any lessons or anything like that. I was thinking we could spend an hour or two each time we logged in to build a decent sized website from scratch. That's basically it. I'm a beginner with about 2 months experience with ASP.NET so we won't have to start from the very beginning, but pretty close. I wanted this site to have a little complexity to it and not just a website for beginners, but something I could study for a while. I'll pay you through PayPal or some other method if you prefer. By the way, it doesn't have to be a website that we work on together. I'll listen to other suggestions too. Maybe we could use an open source site/app to walk-through and study and modify. I've looked at 'My Web Pages Starter Kit 1.30', 'SubText 2.1.2', 'nopCommerce 1.5', and some others. They were all beyond me, and I couldn't make sense of any of the source code. But if you use and are really familiar with an open source app/site that I can download, we could study that. Here are some technical specs about the site I'd like to build/study: ASP.NET 2.0+ (preferably 3.5+, but I don't really care) C# / VB.NET ( don't really care, I suck at both. This is more about ASP.NET and helping me understand the structure of an ASP.NET website and the .NET framework in general. ) SQL Server ( I have SQL Server 2008 express and would someday like to learn how to use this thing. ) JavaScript / AJAX ( at least some use of this ) XML ( basically, I'd like to spend some time in the web.config file, and have some sense of what's going on in there. ) ASP.NET Folders ( I'd like to work with all of the ASP.NET folders if possible: App_Code, App_GlobalResources, etc.. and understand what does/doesn't go in them. Hopefully we can build more than one theme too. ) Assemblies ( how do you create a .dll and use it across different websites? maybe you could suggest a third party .dll that we could use ) Web Service ( I read about this once but didn't really get it ) I can't think of anything else but the above will definitely keep me busy. Hopefully we could make use of a lot of the server controls too (the nav controls gave me a headache when I tried customizing them). Is someone willing to help? I'll pay through PayPal 15 bucks an hour. I live in the Dallas, Texas (US) area so we'd have to synchronize time zones and agree on a day(s)/time of the week. I prefer working at night and on the weekends because I work during the week but whatever your schedule allows too. If you'd like to help me, can you post: years of experience with ASP.NET, your Time zone and time you're available and any ideas you might have about how you'd like to tutor? THANK YOU.

  • Calculus? Need help solving for a time-dependent variable given some other variables.

    - by user451527
    Long story short, I'm making a platform game. I'm not old enough to have taken Calculus yet, so I know not of derivatives or integrals, but I know of them. The desired behavior is for my character to automagically jump when there is a block to either side of him that is above the one he's standing on; for instance, stairs. This way the player can just hold left / right to climb stairs, instead of having to spam the jump key too. The issue is with the way I've implemented jumping; I've decided to go mario-style, and allow the player to hold 'jump' longer to jump higher. To do so, I have a 'jump' variable which is added to the player's Y velocity. The jump variable increases to a set value when the 'jump' key is pressed, and decreases very quickly once the 'jump' key is released, but decreases less quickly so long as you hold the 'jump' key down, thus providing continuous acceleration up as long as you hold 'jump.' This also makes for a nice, flowing jump, rather than a visually jarring, abrupt acceleration. So, in order to account for variable stair height, I want to be able to calculate exactly what value the 'jump' variable should get in order to jump exactly to the height of the stair; preferably no more, no less, though slightly more is permissible. This way the character can jump up steep or shallow flights of stairs without it looking weird or being slow. There are essentially 5 variables in play: h -the height the character needs to jump to reach the stair top<br> j -the jump acceleration variable<br> v -the vertical velocity of the character<br> p -the vertical position of the character<br> d -initial vertical position of the player minus final position<br> Each timestep:<br> j -= 1.5; //the jump variable's deceleration<br> v -= j; //the jump value's influence on vertical speed<br> v *= 0.95; //friction on the vertical speed<br> v += 1; //gravity<br> p += v; //add the vertical speed to the vertical position<br> v-initial is known to be zero<br> v-final is known to be zero<br> p-initial is known<br> p-final is known<br> d is known to be p-initial minus p-final<br> j-final is known to be zero<br> j-initial is unknown<br> Given all of these facts, how can I make an equation that will solve for j? tl;dr How do I Calculus? Much thanks to anyone who's made it this far and decides to plow through this problem.

  • Internet Explorer Automation: how to suppress Open/Save dialog?

    - by Vladimir Dyuzhev
    When controlling IE instance via MSHTML, how to suppress Open/Save dialogs for non-HTML content? I need to get data from another system and import it into our one. Due to budget constraints no development (e.g. WS) can be done on the other side for some time, so my only option for now is to do web scrapping. The remote site is ASP.NET-based, so simple HTML requests won't work -- too much JS. I wrote a simple C# application that uses MSHTML and SHDocView to control an IE instance. So far so good: I can perform login, navigate to desired page, populate required fields and do submit. Then I face a couple of problems: First is that report is opening in another window. I suspect I can attach to that window too by enumerating IE windows in the system. Second, more troublesome, is that report itself is CSV file, and triggers Open/Save dialog. I'd like to avoid it and make IE save the file into given location OR I'm fine with programmatically clicking dialog buttons too (how?) I'm actually totally non-Windows guy (unix/J2EE), and hope someone with better knowledge would give me a hint how to do those tasks. Thanks! UPDATE I've found a promising document on MSDN: http://msdn.microsoft.com/en-ca/library/aa770041.aspx Control the kinds of content that are downloaded and what the WebBrowser Control does with them once they are downloaded. For example, you can prevent videos from playing, script from running, or new windows from opening when users click on links, or prevent Microsoft ActiveX controls from downloading or executing. Slowly reading through... UPDATE 2: MADE IT WORK, SORT OF... Finally I made it work, but in an ugly way. Essentially, I register a handler "before navigate", then, in the handler, if the URL is matching my target file, I cancel the navigation, but remember the URL, and use WebClient class to access and download that temporal URL directly. I cannot copy the whole code here, it contains a lot of garbage, but here are the essential parts: Installing handler: _IE2.FileDownload += new DWebBrowserEvents2_FileDownloadEventHandler(IE2_FileDownload); _IE.BeforeNavigate2 += new DWebBrowserEvents2_BeforeNavigate2EventHandler(IE_OnBeforeNavigate2); Recording URL and then cancelling download (thus preventing Save dialog to appear): public string downloadUrl; void IE_OnBeforeNavigate2(Object ob1, ref Object URL, ref Object Flags, ref Object Name, ref Object da, ref Object Head, ref bool Cancel) { Console.WriteLine("Before Navigate2 "+URL); if (URL.ToString().EndsWith(".csv")) { Console.WriteLine("CSV file"); downloadUrl = URL.ToString(); } Cancel = false; } void IE2_FileDownload(bool activeDocument, ref bool cancel) { Console.WriteLine("FileDownload, downloading "+downloadUrl+" instead"); cancel = true; } void IE_OnNewWindow2(ref Object o, ref bool cancel) { Console.WriteLine("OnNewWindow2"); _IE2 = new SHDocVw.InternetExplorer(); _IE2.BeforeNavigate2 += new DWebBrowserEvents2_BeforeNavigate2EventHandler(IE_OnBeforeNavigate2); _IE2.Visible = true; o = _IE2; _IE2.FileDownload += new DWebBrowserEvents2_FileDownloadEventHandler(IE2_FileDownload); _IE2.Silent = true; cancel = false; return; } And in the calling code using the found URL for direct download: ... driver.ClickButton(".*_btnRunReport"); driver.WaitForComplete(); Thread.Sleep(10000); WebClient Client = new WebClient(); Client.DownloadFile(driver.downloadUrl, "C:\\affinity.dump"); (driver is a simple wrapper over IE instance = _IE) Hope that helps someone.

  • Recommended integration mechanism for bi-directional, authenticated, encrypted connection in C clien

    - by rcampbell
    Let me first give an example. Imagine you have a single server running a JVM application. This server keeps a collection of N equations, once for each client: Client #1: 2x Client #2: 1 + y Client #3: z/4 This server includes an HTTP interface so that random visitors can type https://www.acme.com/client/3 int their browsers and see the latest evaluated result of z/4. The tricky part is that either the client or the server may change the variable value at any time, informing the other party immediately. More specifically, Client #3 - a C app - can initially tell the server that z = 20. An hour later that same client informs the server that z = 23. Likewise the server can later inform the client that z = 28. As caf pointed out in the comments, there can be a race condition when values are changed by the client and server simultaneously. The solution would be for both client and server to send the operation performed in their message, which would need to be executed by the other party. To keep things simple, let's limit the operations to (commutative) addition, allowing us to disregard message ordering. For example, the client seeds the server with z = 20: server:z=20, client:z=20 server sends {+3} message (so z=23 locally) & client sends {-2} message (so z=18 locally) at the exact same time server receives {-2} message at some point, adds to his local copy so z=21 client receives {+3} message at some point, adds to his local copy so z=21 As long as all messages are eventually evaluated by both parties, the correct answer will eventually be given to the users of the client and server since we limited ourselves to commutative operations (addition of 3 and -2). This does mean that both client and server can be returning incorrect answers in the time it takes for messages to be exchanged and processed. While undesirable, I believe this is unavoidable. Some possible implementations of this idea include: Open an encrypted, always on TCP socket connection for communication Pros: no additional infrastructure needed, client and server know immediately if there is a problem (disconnect) with the other party, fairly straightforward (except the the encryption), native support from both JVM and C platforms Cons: pretty low-level so you end up writing a lot yourself (protocol, delivery verification, retry-on-failure logic), probably have a lot of firewall headaches during client app installation Asynchronous messaging (ex: ActiveMQ) Pros: transactional, both C & Java integration, free up the client and server apps from needing retry logic or delivery verification, pretty straightforward encryption, easy extensibility via message filters/routers/etc Cons: need additional infrastructure (message server) which must never fail, Database or file system as asynchronous integration point Same pros/cons as above but messier RESTful Web Service Pros: simple, possible reuse of the server's existing REST API, SSL figures out the encryption problem for you (maybe use RSA key a la GitHub for authentication?) Cons: Client now needs to run a C HTTP REST server w/SSL, client and server need retry logic. Axis2 has both a Java and C version, but you may be limited to SOAP. What other techniques should I be evaluating? What real world experiences have you had with these mechanisms? Which do you recommend for this problem and why?

  • Windows Form hangs when running threads

    - by Benjamin Ortuzar
    JI have written a .NET C# Windows Form app in Visual Studio 2008 that uses a Semaphore to run multiple jobs as threads when the Start button is pressed. It’s experiencing an issue where the Form goes into a comma after being run for 40 minutes or more. The log files indicate that the current jobs complete, it picks a new job from the list, and there it hangs. I have noticed that the Windows Form becomes unresponsive when this happens. The form is running in its own thread. This is a sample of the code I am using: protected void ProcessJobsWithStatus (Status status) { int maxJobThreads = Convert.ToInt32(ConfigurationManager.AppSettings["MaxJobThreads"]); Semaphore semaphore = new Semaphore(maxJobThreads, maxJobThreads); // Available=3; Capacity=3 int threadTimeOut = Convert.ToInt32(ConfigurationManager.AppSettings["ThreadSemaphoreWait"]);//in Seconds //gets a list of jobs from a DB Query. List<Job> jobList = jobQueue.GetJobsWithStatus(status); //we need to create a list of threads to check if they all have stopped. List<Thread> threadList = new List<Thread>(); if (jobList.Count > 0) { foreach (Job job in jobList) { logger.DebugFormat("Waiting green light for JobId: [{0}]", job.JobId.ToString()); if (!semaphore.WaitOne(threadTimeOut * 1000)) { logger.ErrorFormat("Semaphore Timeout. A thread did NOT complete in time[{0} seconds]. JobId: [{1}] will start", threadTimeOut, job.JobId.ToString()); } logger.DebugFormat("Acquired green light for JobId: [{0}]", job.JobId.ToString()); // Only N threads can get here at once job.semaphore = semaphore; ThreadStart threadStart = new ThreadStart(job.Process); Thread thread = new Thread(threadStart); thread.Name = job.JobId.ToString(); threadList.Add(thread); thread.Start(); } logger.Info("Waiting for all threads to complete"); //check that all threads have completed. foreach (Thread thread in threadList) { logger.DebugFormat("About to join thread(jobId): {0}", thread.Name); if (!thread.Join(threadTimeOut * 1000)) { logger.ErrorFormat("Thread did NOT complete in time[{0} seconds]. JobId: [{1}]", threadTimeOut, thread.Name); } else { logger.DebugFormat("Thread did complete in time. JobId: [{0}]", thread.Name); } } } logger.InfoFormat("Finished Processing Jobs in Queue with status [{0}]...", status); } //form methods private void button1_Click(object sender, EventArgs e) { buttonStop.Enabled = true; buttonStart.Enabled = false; ThreadStart threadStart = new ThreadStart(DoWork); workerThread = new Thread(threadStart); serviceStarted = true; workerThread.Start(); } private void DoWork() { EmailAlert emailAlert = new EmailAlert (); // start an endless loop; loop will abort only when "serviceStarted" flag = false while (serviceStarted) { emailAlert.ProcessJobsWithStatus(0); // yield if (serviceStarted) { Thread.Sleep(new TimeSpan(0, 0, 1)); } } // time to end the thread Thread.CurrentThread.Abort(); } //job.process() public void Process() { try { //sets the status, DateTimeStarted, and the processId this.UpdateStatus(Status.InProgress); //do something logger.Debug("Updating Status to [Completed]"); //hits, status,DateFinished this.UpdateStatus(Status.Completed); } catch (Exception e) { logger.Error("Exception: " + e.Message); this.UpdateStatus(Status.Error); } finally { logger.Debug("Relasing semaphore"); semaphore.Release(); } I have tried to log what I can into a file to detect where the problem is happening, but so far I haven't been able to identify where this happens. Losing control of the Windows Form makes me think that this has nothing to do with processing the jobs. Any ideas?

  • RackSpace Cloud Strips $_SESSION if URL Has Certain File Extensions

    - by macinjosh
    The Situation I am creating a video training site for a client on the RackSpace Cloud using the traditional LAMP stack (RackSpace's cloud has both Windows and LAMP stacks). The videos and other media files I'm serving on this site need to be protected as my client charges money for access to them. There is no DRM or funny business like that, essentially we store the files outside of the web root and use PHP to authenticate user's before they are able to access the files by using mod_rewrite to run the request through PHP. So let's say the user requests a file at this URL: http://www.example.com/uploads/preview_image/29.jpg I am using mod_rewrite to rewrite that url to: http://www.example.com/files.php?path=%2Fuploads%2Fpreview_image%2F29.jpg Here is a simplified version of the files.php script: <?php // Setups the environment and sets $logged_in // This part requires $_SESSION require_once('../../includes/user_config.php'); if (!$logged_in) { // Redirect non-authenticated users header('Location: login.php'); } // This user is authenticated, continue $content_type = "image/jpeg"; // getAbsolutePathForRequestedResource() takes // a Query Parameter called path and uses DB // lookups and some string manipulation to get // an absolute path. This part doesn't have // any bearing on the problem at hand $file_path = getAbsolutePathForRequestedResource($_GET['path']); // At this point $file_path looks something like // this: "/path/to/a/place/outside/the/webroot" if (file_exists($file_path) && !is_dir($file_path)) { header("Content-Type: $content_type"); header('Content-Length: ' . filesize($file_path)); echo file_get_contents($file_path); } else { header('HTTP/1.0 404 Not Found'); header('Status: 404 Not Found'); echo '404 Not Found'; } exit(); ?> The Problem Let me start by saying this works perfectly for me. On local test machines it works like a charm. However once deployed to the cloud it stops working. After some debugging it turns out that if a request to the cloud has certain file extensions like .JPG, .PNG, or .SWF (i.e. extensions of typically static media files.) the request is routed to a cache system called Varnish. The end result of this routing is that by the time this whole process makes it to my PHP script the session is not present. If I change the extension in the URL to .PHP or if I even add a query parameter Varnish is bypassed and the PHP script can get the session. No problem right? I'll just add a meaningless query parameter to my requests! Here is the rub: The media files I am serving through this system are being requested through compiled SWF files that I have zero control over. They are generated by third-party software and I have no hope of adding or changing the URLs that they request. Are there any other options I have on this? Update: I should note that I have verified this behavior with RackSpace support and they have said there is nothing they can do about it.

  • MasterDetails Loading on Demand problem

    - by devnet247
    Hi As an exercise to learn wpf and understand how binding works I have an example that works.However when I try to load on demand I fail miserably. I basically have 3 classes Country-City-Hotels If I load ALL in one go it all works if I load on demand it fails miserably. What Am I doing wrong? Works <Window x:Class="MasterDetailCollectionViewSource.CountryCityHotelWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="CountryCityHotelWindow" Height="300" Width="450"> <Window.Resources> <CollectionViewSource Source="{Binding}" x:Key="cvsCountryList"/> <CollectionViewSource Source="{Binding Source={StaticResource cvsCountryList},Path=Cities}" x:Key="cvsCityList"/> <CollectionViewSource Source="{Binding Source={StaticResource cvsCityList},Path=Hotels}" x:Key="cvsHotelList"/> </Window.Resources> <Grid> <Grid.ColumnDefinitions> <ColumnDefinition/> <ColumnDefinition/> <ColumnDefinition/> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition/> </Grid.RowDefinitions> <TextBlock Grid.Column="0" Grid.Row="0" Text="Countries"/> <TextBlock Grid.Column="1" Grid.Row="0" Text="Cities"/> <TextBlock Grid.Column="2" Grid.Row="0" Text="Hotels"/> <ListBox Grid.Column="0" Grid.Row="1" Name="lstCountries" ItemsSource="{Binding Source={StaticResource cvsCountryList}}" DisplayMemberPath="Name" SelectionChanged="OnSelectionChanged"/> <ListBox Grid.Column="1" Grid.Row="1" Name="lstCities" ItemsSource="{Binding Source={StaticResource cvsCityList}}" DisplayMemberPath="Name" SelectionChanged="OnSelectionChanged"/> <ListBox Grid.Column="2" Grid.Row="1" Name="lstHotels" ItemsSource="{Binding Source={StaticResource cvsHotelList}}" DisplayMemberPath="Name" SelectionChanged="OnSelectionChanged"/> </Grid> </Window> DOES NOT WORK Xaml is the same as above, however I have added the following that fetches stuff on demand. It loads the countries only as opposed to the other one where it Loads everything at once and not code behind is necessary. public CountryCityHotelWindow() { InitializeComponent(); //Load only country Initially lstCountries.ItemsSource=Repository.GetCountries(); DataContext = lstCountries; } private void OnSelectionChanged(object sender, SelectionChangedEventArgs e) { var lstBox = (ListBox)e.OriginalSource; switch (lstBox.Name) { case "lstCountries": var country = lstBox.SelectedItem as Country; if (country == null) return; lstCities.ItemsSource = Repository.GetCities(country.Name); break; case "lstCities": var city = lstBox.SelectedItem as City; if (city == null) return; lstHotels.ItemsSource = Repository.GetHotels(city.Name); break; case "lstHotels": break; } } What Am I doing Wrong? Thanks

  • segmented controls mangled during initial transition animation

    - by dLux
    greetings and salutations folks, i'm relatively new to objective c & iphone programming, so bare with me if i've overlooked something obvious.. i created a simple app to play with the different transition animations, setting up a couple segmented controls and a slider.. (Flip/Curl), (left/right) | (up/down), (EaseInOut/EaseIn/EaseOut/Linear) i created a view controller class, and the super view controller switches between 2 instances of the sub class. as you can see from the following image, the first time switching to the 2nd instance, while the animation is occurring the segmented controls are mangled; i'd guess they haven't had enuff time to draw themselves completely.. http://img689.imageshack.us/img689/2320/mangledbuttonsduringtra.png they're fine once the animation is done, and any subsequent times.. if i specify cache:NO in the setAnimationTransition it helps, but there still seems to be some sort of progressive reveal for the text in the segmented controls; they still don't seem to be pre-rendered or initialized properly.. (and surely there's a way to do this while caching the view being transitioned to, since in this case the view isn't changing and should be cacheable.) i'm building my code based on a couple tutorials from a book, so i updated the didReceiveMemoryWarning to set the instanced view controllers to nil; when i invoke a memory warning in the simulator, i assume it's purging the other view, and it acts like a first transition after loading, the view being transitioned to appears just like the image above.. i guess it can't hurt to include the code (sorry if it's considered spamming), this is basically half of it, with a similar chunk following this in an else statement, for the case of the 2nd side being present, switching back to the 1st..: - (IBAction)switchViews:(id)sender { [UIView beginAnimations:@"Transition Animation" context:nil]; if (self.sideBViewController.view.superview == nil) // sideA is active, sideB is coming { if (self.sideBViewController == nil) { SideAViewController *sBController = [[SideAViewController alloc] initWithNibName:@"SideAViewController" bundle:nil]; self.sideBViewController = sBController; [sBController release]; } [UIView setAnimationDuration:sideAViewController.transitionDurationSlider.value]; if ([sideAViewController.transitionAnimation selectedSegmentIndex] == 0) { // flip: 0 == left, 1 == right if ([sideAViewController.flipDirection selectedSegmentIndex] == 0) [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.view cache:YES]; else [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:self.view cache:YES]; } else { // curl: 0 == up, 1 == down if ([sideAViewController.curlDirection selectedSegmentIndex] == 0) [UIView setAnimationTransition:UIViewAnimationTransitionCurlUp forView:self.view cache:YES]; else [UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.view cache:YES]; } if ([sideAViewController.animationCurve selectedSegmentIndex] == 0) [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; else if ([sideAViewController.animationCurve selectedSegmentIndex] == 1) [UIView setAnimationCurve:UIViewAnimationCurveEaseIn]; else if ([sideAViewController.animationCurve selectedSegmentIndex] == 2) [UIView setAnimationCurve:UIViewAnimationCurveEaseOut]; else if ([sideAViewController.animationCurve selectedSegmentIndex] == 3) [UIView setAnimationCurve:UIViewAnimationCurveLinear]; [sideBViewController viewWillAppear:YES]; [sideAViewController viewWillDisappear:YES]; [sideAViewController.view removeFromSuperview]; [self.view insertSubview:sideBViewController.view atIndex:0]; [sideBViewController viewDidAppear:YES]; [sideAViewController viewDidDisappear:YES]; } any other tips or pointers about writing good clean code is also appreciated, i realize i still have a lot to learn.. thank u for ur time, -- d

  • wxPthon problems with Wrapping StaticText

    - by Scott B
    Hello. I am having an issue with wxPython. A simplified version of the code is posted below (white space, comments, etc removed to reduce size - but the general format to my program is kept roughly the same). When I run the script, the static text correctly wraps as it should, but the other items in the panel do not move down (they act as if the statictext is only one line and thus not everything is visible). If I manually resize the window/frame, even just a tiny amount, everything gets corrected and displays as it is should. I took screen shots to show this behavior, but I just created this account and thus don't have the required 10 reputation points to be allowed to post pictures. Why does it not display correctly to begin with? I've tried all sorts of combination's of GetParent().Refresh() or Update() and GetTopLevelParent().Update() or Refresh(). I've tried everything I can think of but cannot get it to display correctly without manually resizing the frame/window. Once re-sized, it works exactly as I want it to. Information: Windows XP Python 2.5.2 wxPython 2.8.11.0 (msw-unicode) Any suggestions? Thanks!
