  • How to implement a lazy loaded Silverlight data grid without using paging

    - by Marc Wittke
    Using the Business Application template from the brand new released RIA Services, you can see lots of examples using the data grid on top of a DomainDataSource in combination with a DataPager. The properties PageSize and LoadSize can be used to adjust the amount of data to be displayed in one page and the data that is prefetched in the background. Now I'd like to have a data grid with a scrollbar and no pager. The underlying DomainDataSource should load only the data that is diplayed in the grid. It should trigger another load, when the user scrolls down to items that are not yet in the data context. Is there any sample implementation how to do this?

  • C# Regex - Match and replace, Auto Increment

    - by Marc Still
    I have been toiling with a problem and any help would be appreciated. Problem: I have a paragraph and I want to replace a variable which appears several times (Variable = @Variable). This is the easy part, but the portion which I am having difficulty is trying to replace the variable with different values. I need for each occurrence to have a different value. For instance, I have a function that does a calculation for each variable. What I have thus far is below: private string SetVariables(string input, string pattern){ Regex rx = new Regex(pattern); MatchCollection matches = rx.Matches(input); int i = 1; if(matches.Count > 0) { foreach(Match match in matches) { rx.Replace(match.ToString(), getReplacementNumber(i)); i++ } } I am able to replace each variable that I need to with the number returned from getReplacementNumber(i) function, but how to I put it back into my original input with the replaced values, in the same order found in the match collection? Thanks in advance! Marcus

  • How to convert a .NET WebService-Method-Result (Soap) into its original datatype?

    - by Marc
    Hello everyone. I have two "identical" webservices (Soap) on two different servers. Don't ask why :-) WebService-1 decides if it handels the request itself or if it passes the request to WebService-2. If so, the response of WebService-2 should directly be returned from WebService-1. The response datatype is complex and self defined. With simple datatypes like 'int or 'string' there would be no problem. The response of WebService-2 is a serialized object (I think it is called "stubs") and theredore it is not possibel to pass this object through as the response of WebService-1 because the type of the objects doesn't match. Is there a simple way to convert the serialised datatype into its original type without buiding a complex converter?

  • AudioRecord problems with non-HTC devices

    - by Marc
    I'm having troubles using AudioRecord. An example using some of the code derived from the splmeter project: private static final int FREQUENCY = 8000; private static final int CHANNEL = AudioFormat.CHANNEL_CONFIGURATION_MONO; private static final int ENCODING = AudioFormat.ENCODING_PCM_16BIT; private int BUFFSIZE = 50; private AudioRecord recordInstance = null; ... android.os.Process.setThreadPriority(android.os.Process.THREAD_PRIORITY_URGENT_AUDIO); recordInstance = new AudioRecord(MediaRecorder.AudioSource.MIC, FREQUENCY, CHANNEL, ENCODING, 8000); recordInstance.startRecording(); short[] tempBuffer = new short[BUFFSIZE]; int retval = 0; while (this.isRunning) { for (int i = 0; i < BUFFSIZE - 1; i++) { tempBuffer[i] = 0; } retval = recordInstance.read(tempBuffer, 0, BUFFSIZE); ... // process the data } This works on the HTC Dream and the HTC Magic perfectly without any log warnings/errors, but causes problems on the emulators and Nexus One device. On the Nexus one, it simply never returns useful data. I cannot provide any other useful information as I'm having a remote friend do the testing. On the emulators (Android 1.5, 2.1 and 2.2), I get weird errors from the AudioFlinger and Buffer overflows with the AudioRecordThread. I also get a major slowdown in UI responsiveness (even though the recording takes place in a separate thread than the UI). Is there something apparent that I'm doing incorrectly? Do I have to do anything special for the Nexus One hardware?

  • Graph call "/me/friends" doesn't contain names if called from a testuser

    - by Marc
    When I log into Facebook with my account and call the Graph API with /me/friends it returns an array like this: [ {id: "6868...", name: "John Smith"}, {id: "7531...", name: "Diane Smith"}, ... ] But if I'm logged in with a Facebook testuser and do the same call I get an array like this: [ {id: "100002927..."}, {id: "100003151..."}, ... ] So I'm missing the name property. Bug? Or did I some mistake? I'm using the JS SDK, but I think that doesn't matter.

  • How to detect Windows 64 bit platform with .net?

    - by Marc
    In a .net 2.0 C# application I use the following code to detect the operating system platform: string os_platform = System.Environment.OSVersion.Platform.ToString();<br/> This returns "Win32NT". The problem is that it returns "Win32NT" even when running on Windows Vista 64bit. Is there any other method to know the correct platform (32 or 64bit)? Note that it should also detect 64bit when run as 32bit app on Windows 64bit.

  • Why does System.Net.Mail work in one part of my c#.net web app, but not in another?

    - by Marc
    I have a web application that is running on IIS within my company's domain, and is being accessed via intranet. I have this application sending out email based on some user actions. For example, its a scheduling application in part, so if a task is completed, an email is sent out notifying other users of that. The problem is, the email works flawlessly in some cases, and not at all in others. I have a login.aspx page which sends out report emails when the page is loaded (its loaded once a day via windows task scheduler) - this always seems to work perfectly. I have an update page which is supposed to send email when text is entered and the "Update" button is clicked - this operation will fail most of the time. Both of these tasks use the same static overloaded method I wrote to send email using System.Net.Mail. I have tried using gmail as my smtp server (instead of our internal one), and get the same results. I investigated whether having the local SMTP Service running makes any difference, and it doesn't seem to. Besides, since C# is server-side code, shouldn't it only matter whats running on the server, and not the client? Please help me figure out whats wrong! Where should I look? What can I try?

  • Images or files in GNU Smalltalk?

    - by Marc
    Hi, I'm new to Smalltalk. I think I understand the basics of the language and now want to start with GNU Smalltalk (as it's free and has bindings for GTK). As I'm coming from the PHP and Java-Corner, I'm not familiar with the concept of the Smalltalk images. And I even read now, that you don't need to use images in GNU Smalltalk. Now I'm confused ;-) So is it possible to work with files and to include the classes I need with the PackageLoader class? I would be happy when I could use my favourite texteditor (vim) for coding instead of an IDE, too ;-) Please enlight me :-)

  • Expanding Rows for Unique Checkboxes

    - by Marc Morgan
    I was just recently given a project for my job to write a script that compares two mysql databases and print out information into an html table. Currently, I am trying to insert a checkbox by each individual's name and when selected, rows pertaining to that individual will expand underneath the person's name. I am combining javascript into my script to do this, although I really have no experience is it. The problem I am having is that when any checkbox is selected, all the rows for each individual is expanding instead of the rows pertaining only to the one individual selected. Here is the coding so far: <?php $link = mysql_connect ($server = "harris.lib.fit.edu", $username = "", $password = "") or die(mysql_error()); $db = mysql_select_db ("library-test") or die(mysql_error()); $ids = mysql_query("SELECT * FROM `ifc_studylog`") or die(mysql_error()); //not single quotes (tilda apostrophy) $x=0; $n=0; while($row = mysql_fetch_array( $ids )) { $tracksid1[$x] = $row['fitID']; $checkin[$x] = $row['checkin']; $checkout[$x] = $row['checkout']; $n++; $x++; } $names = mysql_query("SELECT * FROM `ifc_users`") or die(mysql_error()); //not single quotes (tilda apostrophy) $x=0; while($row = mysql_fetch_array( $names )) { $tracksnamefirst[$x] = $row['firstName']; $tracksnamesecond[$x] = $row['lastname']; $tracksid2[$x] = $row['fitID']; $tracksuser[$x] = $row['tracks']; $x++; } $x=0; foreach($tracksid2 as $comparename) { $chk = strval($x); ?> <script type='text/javascript' src='http://code.jquery.com/jquery-1.4.2.js'></script> <script type='text/javascript'> $(window).load(function () { $('.varx').click(function () { $('.text').toggle(this.checked); });}); </script> <?php echo '<td><input id = "<?=$chk?>" type="checkbox" class="varx" /></td>'; echo '<td align="center">'.$comparename.'</td>'; echo'<td align="center">'.$tracksnamefirst[$x].'</td>'; echo'<td align="center">'.$tracksnamesecond[$x].'</td>'; $z=0; foreach($tracksid1 as $compareid) { $HH=0; $MM =0; $SS =0; if($compareid == $comparename)// && $tracks==$tracksuser[$x]) { $SS = sprintf("%02s",(($checkout[$z]-$checkin[$z])%60)); $MM = sprintf("%02s",(($checkout[$z]-$checkin[$z])/60 %60)); $HH = sprintf("%02s",(($checkout[$z]-$checkin[$z])/3600 %24)); // echo'<td align="center">'.$HH.':'.$MM.':'.$SS.'</td>'; echo '</tr>'; echo '<tr>'; echo "<td id='txt' class='text' align='center' colspan='2' style='display:none'></td>"; echo "<td id='txt' class='text' align='center' style='display:none'>".$checkin[$z]."</td>"; echo '</tr>'; } echo '<tr>'; $z++; echo '</tr>'; } $x++; } } ?> Any Help is appreciated and sorry if I am too vague on the subject.

  • jQuery UI problem centering a dialog

    I've got a jQuery dialog box that does display and respond to button clicks correctly. Unfortunately it's always positioned at 0, 0 in the browser window despite my attempts to convince it otherwise. Any ideas? var $dialog = $('<div></div>') .html('my message') .dialog({ autoOpen: false, title: 'my title', position: 'center', bgiframe: true }); $dialog.dialog('option', 'buttons', buttons); $dialog.dialog('option', 'position', "center"); $dialog.dialog("open");

  • PHP Preg_replace after a specific amount of characters with a conditional

    - by Marc Ripley
    I've been working on this for a bit, but my regex is weak. I need to check to see if a number is a whole number (single digit) and append a ".001" to it if so. The problem is, it's in the middle of a line with values separated by commas. MATERIALS,1,1,9999;1 4PL1 PB_Mel,,1,6,0.173,0.173,0.375,0,0.375,0,0,0,0,2,0,1,1 Needs to be MATERIALS,1,1,9999;1 4PL1 PB_Mel,,1.001,6,0.173,0.173,0.375,0,0.375,0,0,0,0,2,0,1,1 The line must start with "MATERIALS". There are more than one MATERIALS lines. The value will always be after 5 commas. I was trying something like this to even replace the number, but I don't think the approach is quite right: $stripped = preg_replace('/(MATERIALS)(,.*?){4}(,\d+?),/', '\2,', $stripped); I tried going through a preg_match_all for if process, to at least get the conditional working, but I still have to replace the lines. for($i=0;$i<sizeof($materialsLines[0]);$i++) { $section = explode(",",$materialsLines[0][$i]); if (strlen($section[5]) == 1) { $section[5] .= ".001"; } $materialsLines[0][$i] = implode(",",$section); }

  • PHP Magic faster than simply setting the class attribute?

    - by Marc Trudel
    Well, not exactly that, but here is an example. Can anyone explain the difference between B and C? How can it be faster to use a magic function to dynamically set a value instead of simply setting the value in the attribute definition? Here is some code: [root@vm-202-167-238-17 ~]# cat test.php; for d in A B C; do echo "------"; ./test.php $d; done; #!/usr/bin/php <?php $className = $argv[1]; class A { public function __get($a) { return 5; } } class B { public $a = 5; } class C { public function __get($a) { $this->a = 5; return 5; } } $a = new $className; $start = microtime(true); for ($i=0; $i < 1000000; $i++) $b = $a->a; $end = microtime(true); echo (($end - $start) * 1000) ." msec\n"; ------ 598.90794754028 msec ------ 205.48391342163 msec ------ 189.7759437561 msec

  • Problem with input filter using doxygen 1.6.3 on windows XP

    - by Marc
    I am trying to use doxygen to generate documentation for some matlab classes I have written. I am using the doxygen-matlab package, which includes a perl script to kludge matlab .m files into c++ style commented files, so that doxygen can read them. In my doxyfile, I have set (according to the instructions) FILTER_PATTERNS = *m=C:/doxygenMatlab/m2cpp.pl However, when the code runs, rather than running the script on the input files, it appears to just open the script using whatever the default windows setting for .pl is. IE, if I associate .pl with notepad, the script is opened by notepad once for each input file doxygen is trying to parse. If I associate .pl with perl.exe, the script runs and throws the no argument error Argument must contain filename -1 at C:\doxygenMatlab\m2cpp.pl line 4. The doxygen documentation says Doxygen will invoke the filter program by executing (via popen()) the command <filter> <input-file> So I am wondering if there is some problem with popen() and windows that I could fix.

  • Voice Control iOS

    - by Marc Tanis
    I would like to build a simple reader app for the iPad 2 that would allow users to navigate/read via voice controls. The app would allow the user to enter a mode where the microphone was live and listened for predefined keywords like 'down', 'up', 'next', 'back', 'home', etc. I don't want to reinvent the wheel on this so I'm just wondering first, if someone has done this already and if not, are there any good tutorials or SDKs available to help with recording someone's voice, and then comparing future output to see if it matches, or just dealing with the microphone in general?

  • Imagecache for non image CCKs?

    - by Marc Bria
    I'm creating a view with images, videos, audio and documents (books) and I like to shown a picture of each of them in a carousel. Everything works nicely with images and videos as far as we added a image-thumbnail (image filefield) to their CCK but we like to show a default image for audio and documents without changing the original CCK. Is it possible with imagecache (may be with imagecache_custom_code or views_custom_php) or we need to look for a different approach? Thanks for your help, m.

  • Seam log4j credential logs

    - by Marc
    In Seam, using log4, I would like to have my info, warn and error always logging the logged in user (if so) name to be logged with whatever the log message is. Being a consistant thing I do not want to have to grab the logged-in user name, and prefix the message. so I attempted to populate the log4j NDC to have it as a field of the log message. Pushing the user name on successful login: NDC.push(credentials.getUsername()); Which works, but the NDC is managed per thread, so once another thread processes a request from the same logged in user, the trace of this user name is lost. I was thinking that there should be a common pattern to accomplish this simple task which is attaching each log message to the logged user, using the NDC or not, to know exactly what user triggered what action. Anyone knows the appropriate way to accomplish this?

Can I use my login data to a file which the Cronjob can always log in?
