  • How do you update table row background color in IE using Javascript/CSS ?

    - by giulio
    I have a table that i want to "highlight" during onmouseover/onmouseout. I already know this is required in IE but not in other browsers. I have managed to detect the events triggering and this TR tag effectively works. (Note that the originating class "contentTableRow" doesn't seem to be causing any issues.) class="contentTableRow" onclick="openForm('SomeID');" onmouseover="highlight('someRowID', true);" onmouseout="highlight('someRowID', false);" id="someRowID" All is fine and dandy, the "highlight" function fires and actually sets the appropriate class. It's just that IE won't process the CSS class name change. Here is a snippet of the CSS I am using to make the change. .HighlightOn { cursor:pointer; background-color: #D1DFFF; } .HighlightOff { background-color: #E1EEFE; } I can see that the Class names are getting updated when I debug it, and also check it in Firebug. But it seems that IE doesn't like this usage of classes with a TR tag.. Is it the way I am structuring the class for Tables ? Any advice ?

  • Pressing back button in ActivityGroup causes it to pause, and then continue shutting down the next t

    - by synic
    Pressing the back button causes onPause to be called, and the app stays paused until it is re-launched by clicking on the icon, at which point, onDestroy gets called, and the main activity continues to shut down. Simple class to demonstrate. Note, as far as I can tell, this only happens on the Nexus One. I can't reproduce it in the emulator or on my Droid. package com.vimtips.testshutdown; import android.app.ActivityGroup; import android.os.Bundle; import android.util.Log; import android.view.KeyEvent; public class MainActivity extends ActivityGroup { private static final String TAG = "MainActivity"; private int counter = 3; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } public boolean onKeyDown(int keyCode, KeyEvent event) { if(keyCode == KeyEvent.KEYCODE_BACK) { if(counter-- > 0) return true; } return super.onKeyDown(keyCode, event); } @Override public void onPause() { super.onPause(); Log.d(TAG, "onPause called"); } @Override public void onDestroy() { super.onDestroy(); if(isFinishing()) { Log.d(TAG, "Shutting down"); } } } And here's the log: I/ActivityManager( 132): Starting activity: Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10100000 cmp=com.vimtips.testshutdown/.MainActivity } I/ActivityManager( 132): Displayed activity com.vimtips.testshutdown/.MainActivity: 305 ms (total 305 ms) D/MainActivity( 1393): onPause called I/ActivityManager( 132): Displayed activity com.vimtips.testshutdown/.MainActivity: 302 ms (total 302 ms) D/MainActivity( 1393): Shutting down This doesn't appear to happen on a normal Activity, just an Activity group, though looking at Android's sourcecode, I can't figure out why. It's causing some serious problems with my app. Anyone know why this would happen?

  • implementing a download manager that supports resuming

    - by Idan K
    hi, I intend on writing a small download manager in C++ that supports resuming (and multiple connections per download). From the info I gathered so far, when sending the http request I need to add a header field with a key of "Range" and the value "bytes=startoff-endoff". Then the server returns a http response with the data between those offsets. So roughly what I have in mind is to split the file to the number of allowed connections per file and send a http request per splitted part with the appropriate "Range". So if I have a 4mb file and 4 allowed connections, I'd split the file to 4 and have 4 http requests going, each with the appropriate "Range" field. Implementing the resume feature would involve remembering which offsets are already downloaded and simply not request those. Is this the right way to do this? What if the web server doesn't support resuming? (my guess is it will ignore the "Range" and just send the entire file) When sending the http requests, should I specify in the range the entire splitted size? Or maybe ask smaller pieces, say 1024k per request? When reading the data, should I write it immediately to the file or do some kind of buffering? I guess it could be wasteful to write small chunks. Should I use a memory mapped file? If I remember correctly, it's recommended for frequent reads rather than writes (I could be wrong). Is it memory wise? What if I have several downloads simultaneously? If I'm not using a memory mapped file, should I open the file per allowed connection? Or when needing to write to the file simply seek? (if I did use a memory mapped file this would be really easy, since I could simply have several pointers). Note: I'll probably be using Qt, but this is a general question so I left code out of it.

  • python __import__() imports from 2 different directories when same module exists in 2 locations

    - by programer_gramer
    Hi, I have a python application , which has directory structure like this. -pythonapp -mainpython.py -module1 -submodule1 -file1.py -file2.py -submodule2 -file3.py -file3.py -submodule3 -file1.py -file2.py -file5.py -file6.py -file7.py when I try to import the python utilities(from mainpython.py) under submodule3 , I get the initial 2 files from submodule1.(please note that submodule1 and 3 have 2 different files with the same name). However the same import works fine when there is no conflict i.e it correctly imports file 5,6,7 from submodule3. Here is the code : name=os.path.splitext(os.path.split("module1\submodule3\file1.py")[1])[0] -- file1.py name here is passed dynamically. module = import(name) //Here is name is like "file1" it works(but with the above said issue, though, when passes the name of the file dynamically), but if I pass complete package as "module1.submodule1.file1" it fails with an ImportError saying that "no module with name file1" Now the question is how do we tell the interpreter to use only the ones under "module1.submodule3.file2"? I am using python This is really urgent one and I have run out of all the tries. Hope some experienced python developers can solve this for me?

  • Google Maps API V3: How to jump to a specific marker from outside the map?

    - by Tom
    I have a map with two markers on it. The initial view of the map only shows one marker, and I want to provide a link next to the map that will move the map to the 2nd marker when clicked. Here's a demo of what I want, using v2 of the API: http://arts.brighton.ac.uk/contact-university-of-brighton-faculty-of-arts (note the links below the map) Here's what I have so far: <script type="text/javascript"> function initialize() { var latlng = new google.maps.LatLng(50.823817, -0.135634); var myOptions = { zoom: 13, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP, mapTypeControlOptions: { style: google.maps.MapTypeControlStyle.DROPDOWN_MENU } , scaleControl: false }; var map = new google.maps.Map(document.getElementById("map"), myOptions); // 1st marker var marker1 = new google.maps.Marker({ position: new google.maps.LatLng(50.823817, -0.135634), map: map, title: 'my title' }); var infowindow = new google.maps.InfoWindow({ content: 'my window content' }); google.maps.event.addListener(marker1, 'click', function() { infowindow.open(map, marker1); }); // 2nd marker var marker2 = new google.maps.Marker({ position: new google.maps.LatLng(51.5262405, -0.074549), map: map, title: 'my 2nd title'}); var infowindow2 = new google.maps.InfoWindow({ content: 'content for my 2nd window' }); google.maps.event.addListener(marker2, 'click', function() { infowindow2.open(map, marker2); }); } </script> So what I'd like to add is a link to marker2, to move the map some 50-odd miles up, e.g. <a href="#marker2">Second location</a>. How would I do this?

  • Why would some $_POST variables go missing for a form with PHP?

    - by Chad Johnson
    Sometimes, multiple times a day in fact, users of my web application are submitting a certain form which has about a dozen form fields, half of which are hidden fields, and half of the $_POST data is simply not present in the processing script. Note that the fields that are not present are at the very bottom of the form. I know this because this raises a fatal error, and an email is dispatched to me which includes the post data. And of course, neither I nor any of the developers on my team can reproduce the problem. Flash is involved in the process, as I'm using a library called Uploadify to display a progress meter. Here is the flow...does anyone have ANY ideas at all why some of the post data would be getting wiped out? User visits edit screen for a page in the CMS I am using. Record id for the page is put into a form as a hidden value. User clicks the Uploadify browse button and selects a file (only single file selection is allowed). User clicks Submit button for my form. jQuery intercepts the form submit action, triggers Uploadify to start uploading, and returns false for the submit action (manually cancelling the form submit event so that Uploadify can take over). Uploadify uploads to a custom process script. Uploadify finishes uploading and triggers the Javascript completion callback. The Javascript callback calls $('#myForm').submit() to submit the form. This happens on multiple browsers (Firefox 3.5, 3.6, Safari, Internet Explorer 7, 8) and multiple platforms (Mac OS 10.5, 10.6 and Windows XP, 7).

  • MySql Geospatial bug..?

    - by ShaChris23
    This question is for Mysql geospatial-extension experts. The following query doesn't the result that I'm expecting: create database test_db; use test_db; create table test_table (g polygon not null); insert into test_table (g) values (geomfromtext('Polygon((0 5,5 10,7 8,2 3,0 5))')); insert into test_table (g) values (geomfromtext('Polygon((2 3,7 8,9 6,4 1,2 3))')); select X(PointN(ExteriorRing(g),1)), Y(PointN(ExteriorRing(g),1)), X(PointN(ExteriorRing(g),2)), Y(PointN(ExteriorRing(g),2)), X(PointN(ExteriorRing(g),3)), Y(PointN(ExteriorRing(g),3)), X(PointN(ExteriorRing(g),4)), Y(PointN(ExteriorRing(g),4)) from test_table where MBRContains(g,GeomFromText('Point(3 6)')); Basically we are creating 2 Polygons, and we are trying to use MBRContains to determine whether a Point is within either of the two polygons. Surprisingly, it returns both polygons! Point 3,6 should only exist in the first inserted polygon. Note that both polygons are tilted (once you draw the polygons on a piece of paper, you will see) How come MySql returns both polygons? I'm using MySql Community Edition 5.1.

  • In Firefox 2, usage of overflow:hidden makes other divs overlap current div

    - by Shankar
    Hi, When I use overflow:hidden for div which is positioned absolute (for menu), other div overlaps. Here is the code. It works fine in FF3. Any help appreciated. Please note that html should be as it is. Also if you can provide solution, just by changing styles of menu div (the div which contains menu text) it is more helpful for me. Thanks in advance Here is the code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head> <title>Title of the document</title> </head> <body> <div style="position:relative"> <div> <div style="height:20px;overflow:hidden"> <div style="position:absolute;width:200px;height:100px;top:0px;background-color:black;z-index:1">menu</div> </div> </div> <div style="position:relative;height:200px;background-color:gray;"></div> </div> </body> </html>

  • Cross-browser padding/margins

    - by Lucifer
    Hi All, I was wondering if you could give me some helpful hints on how to correct this issue? I have a main menu on my site, the code for it is as follows: li:hover { background-color: #222222; padding-top: 8px; padding-bottom: 9px; } And here's a demo of what it actually looks like: The problem is that when I hover over a menu option (li), the background appears, but it overflows to the outside of the menu's background, and makes it look really dodgy/crap/cheap/yuck! Note that (obviously) when I change the padding to make it display correctly in these browsers, it appears too small in height in IE! So I'm screwed either way. How can I make little imperfections like this look the same in all browsers? Update: HTML (The menu): <ul class="menu"> <li class="currentPage" href="index.php"><a>Home</a></li> <li><a href="services.php">Services</a></li> <li><a href="support.php">Support</a></li> <li><a href="contact.php">Contact Us</a></li> <li><a href="myaccount/" class="myaccount">My Account</a></li> </ul> The CSS: .menu { margin-top: 5px; margin-right: 5px; width: 345px; float: right; } li { font-size: 9pt; color: whitesmoke; padding-left: 6px; padding-right: 8px; display: inline; list-style: none; } li:hover { background-color: #222222; padding-top: 8px; padding-bottom: 9px; }

  • SQL Server 2008: Comparing similar records - Need to still display an ID for a record when the JOIN has no matches

    - by aleppke
    I'm writing a SQL Server 2008 report that will compare genetic test results for animals. A genetic test consists of an animalId, a gene and a result. Not all animals will have the same genes tested but I need to be able to display the results side-by-side for a given set of animals and only include the genes that are present for at least one of the selected animals. My TestResult table has the following data in it: animalId gene result 1 a CC 1 b CT 1 d TT 2 a CT 2 b CT 2 c TT 3 a CT 3 b TT 3 c CC 3 d CC 3 e TT I need to generate a result set that looks like the following. Note that Animal 3 is not being displayed (user doesn't want to see its results) and neither are results for Gene "e" since neither Animal 1 nor Animal 2 have a result for that gene: SireID SireResult CalfID CalfResult Gene 1 CC 2 CT a 1 CT 2 CT b 1 NULL 2 TT c 1 TT 2 NULL d But I can only manage to get this: SireID SireResult CalfID CalfResult Gene 1 CC 2 CT a 1 CT 2 CT b NULL NULL 2 TT c 1 TT NULL NULL d This is the query I'm using. SELECT sire.animalId AS 'SireID' ,sire.result AS 'SireResult' ,calf.animalId AS 'CalfID' ,calf.result AS 'CalfResult' ,sire.gene AS 'Gene' FROM (SELECT s.animalId ,s.result ,m1.gene FROM (SELECT [animalId ] ,result ,gene FROM TestResult WHERE animalId IN (1)) s FULL JOIN (SELECT DISTINCT gene FROM TestResult WHERE animalId IN (1, 2)) m1 ON s.marker = m1.marker) sire FULL JOIN (SELECT c.animalId ,c.result ,m2.gene FROM (SELECT animalId ,result ,gene FROM TestResult WHERE animalId IN (2)) c FULL JOIN (SELECT DISTINCT gene FROM TestResult WHERE animalId IN (1, 2)) m2 ON c.gene = m2.gene) calf ON sire.gene = calf.gene How do I get the SireIDs and CalfIDs to display their values when they don't have a record associated with a particular Gene? I was thinking of using COALESCE but I can't figure out how to specify the correct animalId to pass in. Any help would be appreciated.

  • POST data getting lost: Content Length = 0

  • Should I move big data blobs in JSON or in separate binary connection?

    - by Amagrammer
    QUESTION: Is it better to send large data blobs in JSON for simplicity, or send them as binary data over a separate connection? If the former, can you offer tips on how to optimize the JSON to minimize size? If the latter, is it worth it to logically connect the JSON data to the binary data using an identifier that appears in both, e.g., as "data" : "< unique identifier " in the JSON and with the first bytes of the data blob being < unique identifier ? CONTEXT: My iPhone application needs to receive JSON data over the 3G network. This means that I need to think seriously about efficiency of data transfer, as well as the load on the CPU. Most of the data transfers will be relatively small packets of text data for which JSON is a natural format and for which there is no point in worrying much about efficiency. However, some of the most critical transfers will be big blobs of binary data -- definitely at least 100 kilobytes of data, and possibly closer to 1 megabyte as customers accumulate a longer history with the product. (Note: I will be caching what I can on the iPhone itself, but the data still has to be transferred at least once.) It is NOT streaming data. I will probably use a third-party JSON SDK -- the one I am using during development is here. Thanks

  • In VB.net websites, VS2008 ALWAYS uses space indentation for new files

    - by Jez
    So, I've changed my settings in Tools | Options | Text Editor, for All Languages, Basic, and C#, to having Block indenting, and 'Keep tabs'. I've also tried this with Smart indenting too. Now, although once I start editing a file, its auto indentation is done with tabs, when I create a new web form in my ASP.net website, VS2008 insists on creating the initial code with space indentation. So for example, I'll get an aspx.vb file for my new page like so: Partial Class Admin_Index Inherits System.Web.UI.Page End Class Note that the 'Inherits' line is SPACE-indented, even though I have the text editor settings set to keep tabs. Is there any way I can make the default created files indented with tabs, not spaces? Or is VS just too stubborn? :-) By the way, please don't just respond and say this is petty as I can quickly change that one line of indentation to using a tab. I know this, but I have a software team that find it irritating as we have an SVN hook that prevents checkins if there's any space-indentation. It would be very useful if any newly-created files have tab indentation from the start, rather than us having to change it every time.

  • Umlaute from JSP-page are misinterpreted

    - by Karin
    I'm getting Input from a JSP page, that can contain Umlaute. (e.g. Ä,Ö,Ü,ä,ö,ü,ß). Whenever an Umlaut is entered in the Input field an incorrect value gets passed on. e.g. If an "ä" (UTF-8:U+00E4) gets entered in the input field, the String that is extracted from the argument is "ä" (UTF-8: U+00C3 and U+00A4) It seems to me as if the UTF-8 hex encoding (which is c3 a4 for an "ä") gets used for the conversion. How can I retrieved the correct value? Here are snippets from the current implementation The JSP-page passes the input value "pk" on to the processing logic: <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> ... <input type="text" name="<%=pk.toString()%>" value="<%=value%>" size="70"/> <button type="submit" title="Edit" value='Save' onclick="action.value='doSave';pk.value='<%=pk.toString()%>'"><img src="icons/run.png"/>Save</button> The value gets retrieved from args and converted to a string: UUID pk = UUID.fromString(args.get("pk")); //$NON-NLS-1$ String value = args.get(pk.toString()); Note: Umlaute that are saved in the Database get displayed correctly on the page.

Question : 1) I need to give this log in representable form to client where he doesn't need to know anything about the bunch of 'my-servers'. All i am supposed to give is timestamp of the data entered my infrastructure and when it left; drilling down to following info. in_timestamp (of 'others_server1' to 'my-server1') out_timestamp (of 'my-server3' to 'others-server2') name status I want to write sql for the same! Can someone help? NOTE : there might not be 3 'my-servers' all the time. It differs from situation to situation. e.g. there might be 4 'my-server' involved for, say, data2! 2) Are there any other alternatives to SQL? I mean stored procs/etc? 3) Optimizations? (The records are huge in number! As of now, it is around 5 million a day. And we are supposed to show records that are upto a week old.) In advance, THANKS FOR THE HELP! :)

  • Windows Installer custom action BEFORE any validation

    - by Marc
    I wrote a Windows Installer custom action based on the tutorial found here: http://www.codeproject.com/kb/install/msicustomaction.aspx My custom action is killing a background process of a given name which could still be opened by the user. The reason is that I don't want users to see the warning that a given EXE is running and must be closed so that setup can continue. This works fine when the MSI passes through the UI sequence as the action is created in "InstallUISequence" table like in the tutorial. However, when the MSI is used silently (right-click and select repair or uninstall), then my custom action isn't executed of course. Where do I have to put my custom action so that it is executed immediately also when run silently? I tried adding it to "InstallExecuteSequence", but the 'app running' warning is still shown. I then tried lowering the sequence number of my custom action to 5, but this also didn't help. Note: I'm using Orca to modify an MSI generated from a Visual Studio setup project. I'm then using the transform file to apply it.

  • DirectShow Filter I wrote dies after 10-24 seconds in Skype video call

    - by Robert Oschler
    I've written a DirectShow push filter for use with Skype using Delphi Pro 6 and the DSPACK DirectShow library. In preview mode, when you test a video input device in the Skype client Video Settings window, my filter works flawlessly. I can leave it up and running for many minutes without an error. However when I start a video call after 10 to 24 seconds, never longer, the video feed freezes. The call continues fine with the call duration counter clicking away the seconds, but the video feed is dead, stuck on whatever frame the freeze happened (although after a long while it turns black which I believe means Skype has given up on the filter). I tried attaching to the process from my debugger with a breakpoint literally set on every method call and none of them are hit once the freeze takes place. It's as if the thread that makes the DirectShow FillBuffer() call to my filter on behalf of Skype is dead or has been shutdown. I can't trace my filter in the debugger because during a Skype call I get weird int 1 and int 3 debugger hard interrupt calls when a Skype video call is in progress. This behavior happens even with my standard web cam input device selected and my DirectShow filter completely unregistered as a ActiveX server. I suspect it might be some "anti-debugging" code since it doesn't happen in video input preview mode. Either way, that is why I had to attach to the process after the fact to see if my FillBuffer() called was still being called and instead discovered that appears to be dead. Note, my plain vanilla USB web cam's DirectShow filter does not exhibit the freezing behavior and works fine for many minutes. There's something about my filter that Skype doesn't like. I've tried Sleep() statements of varying intervals, no Sleep statements, doing virtually nothing in the FillBuffer() call. Nothing helps. If anyone has any ideas on what might be the culprit here, I'd like to know. Thanks, Robert

  • Sending jQuery.ajax data simultaneous to a form submit

    - by dscher
    I have a bit of a conundrum. I have a form which has numerous fields. There is one field for links where you enter a link, click an add button, and the link(using jQuery) gets added to a link_array. I want this array to be sent via the jQuery.ajax method when the form is submitted. If I send the link_array using $.ajax like this: $.ajax({ type: "POST", url: "add_stock", dataType: "json", data: { "links": link_array } }); when the add link button is selected the data goes no problem to the correct place and gets put in the db correctly. If I bind the above function to the submit form button using $(#stock_form).submit(..... then the rest of the form data is sent but not the link_array. I can obviously pass the link array back into a hidden field in HTML but then I'd have to unpack the array into comma separate values and break the comma-separated string apart in PHP. It just seems 100X easier to unpack the Javascript array in PHP without an other fuss. So, how is it that you can send an array from javascript using $.ajax concurrent to the rest of the $_POST data in HTML? Please note that I'm using Kohana 3.0 framework but really that shouldn't make a difference, what I want to do is add this js array to the $_POST array that is already going. Thanks!

  • Resizing window causes black strips

    - by Paja
    I have a form, which sets these styles in constructor: this.SetStyle(ControlStyles.AllPaintingInWmPaint, true); this.SetStyle(ControlStyles.UserPaint, true); this.SetStyle(ControlStyles.ResizeRedraw, true); this.SetStyle(ControlStyles.OptimizedDoubleBuffer, true); And I draw some rectangles in Paint event. There are no controls on the form. Hovewer, when I resize the form, there are black strips at right and bottom of the form. Is there any way to get rid of them? I've tried everything, listening for WM_ERASEBKGND in WndProc, manually drawing the form on WM_PAINT, implementing custom double buffer, etc. Is there anything else I could try? I've found this: https://connect.microsoft.com/VisualStudio/feedback/details/522441/custom-resizing-of-system-windows-window-flickers and it looks like it is a bug in DWM, but I just hope I can do some workaround. Please note that I must use double buffering, since I want to draw pretty intense graphic presentation in the Paint event. I develop in C# .NET 2.0, Win7.

    I'm writing a java game and I want to implement a power meter for how hard you are going to shoot something. I need to write a function that takes a int between 0 - 100, and based on how high that number is, it will return a color between Green (0 on the power scale) and Red (100 on the power scale). Similar to how volume controls work: What operation do I need to do on the Red, Green, and Blue components of a color to generate the colors between Green and Red? So, I could run say, getColor(80) and it will return an orangish color (its values in R, G, B) or getColor(10) which will return a more Green/Yellow rgb value. I know I need to increase components of the R, G, B values for a new color, but I don't know specifically what goes up or down as the colors shift from Green-Red. Progress: I ended up using HSV/HSB color space because I liked the gradiant better (no dark browns in the middle). The function I used was (in java): public Color getColor(double power) { double H = power * 0.4; // Hue (note 0.4 = Green, see huge chart below) double S = 0.9; // Saturation double B = 0.9; // Brightness return Color.getHSBColor((float)H, (float)S, (float)B); } Where "power" is a number between 0.0 and 1.0. 0.0 will return a bright red, 1.0 will return a bright green. Java Hue Chart: Thanks everyone for helping me with this!

  • Perl to Ruby conversion (multidimensional arrays)

    - by Alex
    I'm just trying to get my head around a multidimensional array creation from a perl script i'm currently converting to Ruby, I have 0 experience in Perl, as in i opened my first Perl script this morning. Here is the original loop: my $tl = {}; for my $zoom ($zoommin..$zoommax) { my $txmin = lon2tilex($lonmin, $zoom); my $txmax = lon2tilex($lonmax, $zoom); # Note that y=0 is near lat=+85.0511 and y=max is near # lat=-85.0511, so lat2tiley is monotonically decreasing. my $tymin = lat2tiley($latmax, $zoom); my $tymax = lat2tiley($latmin, $zoom); my $ntx = $txmax - $txmin + 1; my $nty = $tymax - $tymin + 1; printf "Schedule %d (%d x %d) tiles for zoom level %d for download ...\n", $ntx*$nty, $ntx, $nty, $zoom unless $opt{quiet}; $tl->{$zoom} = []; for my $tx ($txmin..$txmax) { for my $ty ($tymin..$tymax) { push @{$tl->{$zoom}}, { xyz => [ $tx, $ty, $zoom ] }; } } } and what i have so far in Ruby: tl = [] for zoom in zoommin..zoommax txmin = cm.tiles.xtile(lonmin,zoom) txmax = cm.tiles.xtile(lonmax,zoom) tymin = cm.tiles.ytile(latmax,zoom) tymax = cm.tiles.ytile(latmin,zoom) ntx = txmax - txmin + 1 nty = tymax - tymin + 1 tl[zoom] = [] for tx in txmin..txmax for ty in tymin..tymax tl[zoom] << xyz = [tx,ty,zoom] puts tl end end end The part i'm unsure of is nested right at the root of the loops, push @{$tl->{$zoom}},{ xyz => [ $tx, $ty, $zoom ] }; I'm sure this will be very simple for a seasoned Perl programmer, thanks! `

  • Comparing two collections for equality

    - by Crossbrowser
    I would like to compare two collections (in C#), but I'm not sure of the best way to implement this efficiently. I've read the other thread about Enumerable.SequenceEqual, but it's not exactly what I'm looking for. In my case, two collections would be equal if they both contain the same items (no matter the order). Example: collection1 = {1, 2, 3, 4}; collection2 = {2, 4, 1, 3}; collection1 == collection2; // true What I usually do is to loop through each item of one collection and see if it exists in the other collection, then loop through each item of the other collection and see if it exists in the first collection. (I start by comparing the lengths). if (collection1.Count != collection2.Count) return false; // the collections are not equal foreach (Item item in collection1) { if (!collection2.Contains(item)) return false; // the collections are not equal } foreach (Item item in collection2) { if (!collection1.Contains(item)) return false; // the collections are not equal } return true; // the collections are equal However, this is not entirely correct, and it's probably not the most efficient way to do compare two collections for equality. An example I can think of that would be wrong is: collection1 = {1, 2, 3, 3, 4} collection2 = {1, 2, 2, 3, 4} Which would be equal with my implementation. Should I just count the number of times each item is found and make sure the counts are equal in both collections? The examples are in some sort of C# (let's call it pseudo-C#), but give your answer in whatever language you wish, it does not matter. Note: I used integers in the examples for simplicity, but I want to be able to use reference-type objects too (they do not behave correctly as keys because only the reference of the object is compared, not the content).

  • Apache HTTP and WEblogic Plug-in Location Directive question

    - by user275633
    All, We are using Weblogic Portal and Apache 2.x http server with the weblogic plug-in for apache for load-balancing. We have an application that right now can only be accessed from one of our managed servers. What I would like to do is us the Location directive to direct all requests for that page to the one managed server and I can't get it to work. The context that the portal tries to forward to is something like /MyWebApp?portalusername= (where equals a legitimate user. For example /MyWebApp?portalusername=joesmith All other applications and the plug-in is load balancing as expected because every now and then you'll get sent to teh second managed server for this particular application and its not deployed. I tried various things in the apache http.conf like the following but can't seem to get it work? Any suggestions? The followign is a snippet of the httpd.conf: (Note formatting did not come thru properly but it is formatted correctly in my httpd.conf) Blockquote Location /MyWebApp SetHandler weblogic-handler WebLogicCluster myserver:7011 Location Blockquote Location / SetHandler weblogic-handler WebLogicCluster myserver:7011, myserver2:7012 Location Thanks in advance.

  • Why is python decode replacing more than the invalid bytes from an encoded string?

    - by dangra
    Trying to decode an invalid encoded utf-8 html page gives different results in python, firefox and chrome. The invalid encoded fragment from test page looks like 'PREFIX\xe3\xabSUFFIX' >>> fragment = 'PREFIX\xe3\xabSUFFIX' >>> fragment.decode('utf-8', 'strict') ... UnicodeDecodeError: 'utf8' codec can't decode bytes in position 6-8: invalid data What follows is the summary of replacement policies used to handle decoding errors by python, firefox and chrome. Note how the three differs, and specially how python builtin removes the valid S (plus the invalid sequence of bytes). by Python The builtin replace error handler replaces the invalid \xe3\xab plus the S from SUFFIX by U+FFFD >>> fragment.decode('utf-8', 'replace') u'PREFIX\ufffdUFFIX' >>> print _ PREFIX?UFFIX The python implementation builtin replace error handler looks like: >>> python_replace = lambda exc: (u'\ufffd', exc.end) As expected, trying this gives same result than builtin: >>> codecs.register_error('python_replace', python_replace) >>> fragment.decode('utf-8', 'python_replace') u'PREFIX\ufffdUFFIX' >>> print _ PREFIX?UFFIX by Firefox Firefox replaces each invalid byte by U+FFFD >>> firefox_replace = lambda exc: (u'\ufffd', exc.start+1) >>> codecs.register_error('firefox_replace', firefox_replace) >>> test_string.decode('utf-8', 'firefox_replace') u'PREFIX\ufffd\ufffdSUFFIX' >>> print _ PREFIX??SUFFIX by Chrome Chrome replaces each invalid sequence of bytes by U+FFFD >>> chrome_replace = lambda exc: (u'\ufffd', exc.end-1) >>> codecs.register_error('chrome_replace', chrome_replace) >>> fragment.decode('utf-8', 'chrome_replace') u'PREFIX\ufffdSUFFIX' >>> print _ PREFIX?SUFFIX The main question is why builtin replace error handler for str.decode is removing the S from SUFFIX. Also, is there any unicode's official recommended way for handling decoding replacements?
