• Java: Cleaing up connection reset (but not by peer).

  - by Zombies

  There seems to be some confusion as well contradicting statements on various SO answers: http://stackoverflow.com/questions/585599/whats-causing-my-java-net-socketexception-connection-reset . You can see here that the accepted answer states that the connecteion was closed by other side. But this is not true, closing a connection doesn't cause a connection reset. It is cauesed by "an underlying TCP/IP error." What I want to know is if a SocketException: Connection reset means really besides "unerlying TCP/IP Error." What really causes this? As I doubt it has anything to do with the connection being closed (since closing a connection isn't an exception worthy flag, and reading from a closed connection is, but that isn't an "underlying TCP/IP error." My hypothesis is this Connection reset is caused from a server's failure to acknowledge an ACK packet (either wholly or just improperly as per TCP/IP). And that a SocketTimeoutException is generated only when no data is generated to be read (since this is thrown during a read after a certain duration, and read is waiting for data, but is not concerned with ACK packets). In other words, read() throws SocketTimeoutException if it didn't read any bytes of actual data (DATA LAYER) in its allotted time.

• Assign a static function to a variable in PHP

  - by Felipe Almeida

  I would like to assign a static function to a variable so that I can send it around as a parameter. For example: class Foo{ private static function privateStaticFunction($arg1,$arg2){ //compute stuff on the args } public static function publicStaticFunction($foo,$bar){ //works $var = function(){ //do stuff }; //also works $var = function($someArg,$someArg2){ //do stuff }; //Fatal error: Undefined class constant 'privateStaticFunction' $var = self::privateStaticMethod; //same error $var = Foo::privateStaticFunction; //compiles, but errors when I try to run $var() somewhere else, as expected //Fatal error: Call to private method Foo::privateStaticMethod() from context '' $var = function(){ return Foo::privateStaticMethod(); }; } } I've tried a few more variations but none of them worked. I don't even expect this sort of functional hacking to work with PHP but hey, who knows? Is it possible to do that in PHP or will I need to come up with some hack using eval? P.S.: LawnGnome on ##php mentioned something about it being possible to do what I want using array('Foo','privateStaticMethod') but I didn't understand what he meant and I didn't press him further as he looked busy.

• Page Entirely Blank Despite Having Source Code! (TinyMCE, FireFox)

  - by Chris Cooper

  Alright guys, here's a tough one... In reference to this page. The page will seemingly randomly not display the output of server when using Firefox (version 3.5). I have not seen this problem occur in Safari or IE. The best way to have the problem occur is just reload the page about 10 times and it ought to have happened by then, and once it does - it'll continue on subsequent refreshes until you change the page. The problem is literally the browser not displaying the output (code). Viewing the source shows all the appropriate code yet the browser displays a blank white page. The web developer and firebug plugins don't show any errors that would indicate the problem. I have tested this on a separate system and OS and it occurs in Firefox on that system as well. The problem did not occur until after TinyMCE (A Rich Text Editor JavaScript library for textareas) was added to the project. TinyMCE works however, where it should. I know this is a confusing problem, but I am completely lost as to what could be causing this significant issue. Thanks in advance. EDIT: If it's any help... I've noticed that if I cause a css file error by changing a stylesheet source to something non-existant (xxx.css), the page will continuously display without a problem (besides whatever related css not showing due to the src change). I've also noticed that causing any simple javascript error with some bad code will cause the page to load properly continuously (besides of course javascript not running on the page). EDIT#2: Moving all <script> tags down at the tail of the <body> 'fixes' (well, hides) this error and the page shows normally. A band-aid.

• SVG text - total length changes depending on zoom

  - by skco

  In SVG (for web-browsers), if i add a <text>-element and add some text to it the total rendered width of the text string will change depending on the scale of the text. Lets say i add "mmmmmmmmmmmmmmmmmmmmmmmmmmA" as text, then i want to draw a vertical line(or other exactly positioned element) intersecting the very last character. Works fine but if i zoom out the text will become shorter or longer and the line will not intersect the text in the right place anymore. The error can be as much as +/- 5 characters width which is unacceptable. The error is also unpredictable, 150% and 160% zoom can add 3 characters length while 155% is 2 charlengths shorter. My zoom is implemented as a scale-transform on the root element of my canvas which is a <g>. I have tried to multiply the font-size with 1000x and scale down equally on the zoom-transform and vice versa in case it was a floating point error but the result is the same. I found the textLength-attribute[1] which is supposed to adjust the total length so the text always end where i choose but it only works in Webkit. Firefox and Opera seems to not care at all about this value (haven't tried in IE9 yet). Is there any way to render text exactly positioned without resorting to homemade filling of font-outlines? [1] http://www.w3.org/TR/SVG11/text.html#TextElementTextLengthAttribute Update Snippet of the structure i'm using <svg> <g transform="scale(1)"> <!--This is the root, i'm changing the scale of this element to zoom --> <g transform="scale(0.014)"> <!--This is a wrapper for multi-line text, scaling, other grouping etc --> <text font-size="1000" textLength="40000">ABDCDEFGHIJKLMNOPQRSTUVXYZÅÄÖabcdefghijklmnopqrstxyzåäö1234567890</text> </g> </g>

• why no implicit conversion from pointer to reference to const pointer.

  - by user316606

  I'll illustrate my question with code: #include <iostream> void PrintInt(const unsigned char*& ptr) { int data = 0; ::memcpy(&data, ptr, sizeof(data)); // advance the pointer reference. ptr += sizeof(data); std::cout << std::hex << data << " " << std::endl; } int main(int, char**) { unsigned char buffer[] = { 0x11, 0x11, 0x11, 0x11, 0x22, 0x22, 0x22, 0x22, }; /* const */ unsigned char* ptr = buffer; PrintInt(ptr); // error C2664: ... PrintInt(ptr); // error C2664: ... return 0; } When I run this code (in VS2008) I get this: error C2664: 'PrintInt' : cannot convert parameter 1 from 'unsigned char *' to 'const unsigned char *&'. If I uncomment the "const" comment it works fine. However shouldn't pointer implicitly convert into const pointer and then reference be taken? Am I wrong in expecting this to work? Thanks!

• Adobe Air, packaged install fails with my trace routine... how come?

  - by artie scie

  I cobbled together some code from here and there for a trace I like... it generates an error to get a stack trace and picks out the traced routine name, I like that detail in the trace log. Problem: it fails in an installed AIR file. I wonder why? I don't expect it to do anything as is... just, I'd prefer it not cause the program to fail! tx artie enter code here static public function XTRACE( ... traceArgs ):void { try { throw new Error(); // make a stack } catch (e:Error) { var stack:String = e.getStackTrace(); var frames:Array = stack.split("\n"); var myFrame:String = String(frames[2]); myFrame = myFrame.replace("\t", ""); // "at " can be followed by some part of the package // you don't want to see. E.g., if your code is all in // com.foo.bar, you can put "at com.foo.bar." so as not // to crowd the display myFrame = myFrame.substr("at ".length); myFrame = myFrame.substring(0, myFrame.indexOf("[")); var now:Date = new Date(); trace(new Date().toLocaleTimeString() + ":" + myFrame + ": " + traceArgs.join(" ")); } }

• File uploads simply do not work - what could be wrong server side?

  - by vanneto

  This has been grinding my gears for at least a week now. I have a site which has a crucial function - the upload component. Without it, the site is completely useless. Now, lots of users have problems uploading files. This is why I implemented a log system that keeps track of what happens when the file is on the server. Problem is, only a minority of problems happen when the file is on the server, the problems happen client side. For example, when I tried SWFUpload the errors where 'I/O Error'. When I changed to Uploadify I get 'HTTP Error'. I am trying to get a more detailed error description as I type this. I am starting to think its not the client or the upload software, but the server. What could be wrong? The following directives for PHP are set: upload_max_filesize 200M post_max_size 200M memory_limit 256M max_execution_time 4200 max_input_time 4200 I simply have no clue why file uploads are failing. They should not fail. I would really appreciate any answers as why the uploads could be failing. Thank you.

• copy rows with special condition

  - by pooria_googooli

  I have a table with a lot of columns. For example I have a table with these columns : ID,Fname,Lname,Tel,Mob,Email,Job,Code,Company,...... ID column is auto number column. I want to copy all rows in this table to this table and change the company column value to 12 in this copied row. I don't want to write name all of the columns because I have a lot of table with a lot of columns. I tried this code but I had this error : declare @c int; declare @i int; select * into CmDet from CmDet; select @C= count(id) from CmDet; while @i < @C begin UPDATE CmDet SET company =12 WHERE company=11 set @i += 1 end error : Msg 2714, Level 16, State 6, Line 3 There is already an object named 'CmDet' in the database. I changed the code to this declare @c int declare @i int insert into CmDet select * from CmDet; select @C= count(id) from CmDet; while @i < @C begin UPDATE CmDet SET company =12 WHERE company=11 set @i += 1 end and I had this error : Msg 8101, Level 16, State 1, Line 3 An explicit value for the identity column in table 'CmDet' can only be specified when a column list is used and IDENTITY_INSERT is ON. What should I do ?

• The type or namespace name 'WebControls' could not be found (are you missing a using directive or an assembly reference?)

• Rails RESTful routs without #new, rspec trouble

  - by pdkl95

  I'm currently writing a Rails app, and hit a somewhat strange quirk. I have a controller PermissionsController, which is mainly for display purposes at the moment. So my routing is locked down: map.resources :permissions, :only => [:index, :show] Unfortunately, when writing the tests, one of the routing tests fails: it "does not recognize #new" do { :get => "/permissions/new" }.should_not be_routable end with the error: Expected 'GET /permissions/new' to fail, but it routed to {"action"=>"show", "id"=>"new", "controller"=>"permissions"} instead Obviously, the #show action's route is matching with /permissions/:id, which also gives the expected error Couldn't find Permission with ID=new if you actually browse to that URL. This is not a serious error, as it is correctly raising an exception with the bad :id parameter, but it's kind of ugly. Is there any way to actually make Rails reject that route? Some trick in the routing options that I'm missing? I suppose I should just leave that test out and ignore it, or maybe remove the whole RESTful idea altogether and go back to a simpler map.connect 'permissions/:id' style. I strongly suspect I'll be expanding this in the future, though, and kind of wanted to keep my controllers consistent with each other. Just having to add occasional :only or :except rules made routes.rb nice and clean...

• iOS: Best Way to do This w/o Calling Method 32 Times?

  - by user1886754

  I'm currently retrieving the Top 100 Scores for one of my leaderboards the following way: - (void) retrieveTop100Scores { __block int totalScore = 0; GKLeaderboard *myLB = [[GKLeaderboard alloc] init]; myLB.identifier = [Team currentTeam]; myLB.timeScope = GKLeaderboardTimeScopeAllTime; myLB.playerScope = GKLeaderboardPlayerScopeGlobal; myLB.range = NSMakeRange(1, 100); [myLB loadScoresWithCompletionHandler:^(NSArray *scores, NSError *error) { if (error != nil) { NSLog(@"%@", [error localizedDescription]); } if (scores != nil) { for (GKScore *score in scores) { NSLog(@"%lld", score.value); totalScore += score.value; } NSLog(@"Total Score: %d", totalScore); [self loadingDidEnd]; } }]; } The problem is I want to do this for 32 leaderboards. What's the best way of achieving this? Using a third party tool (Game Center Manager), I can get the following line to return a dictionary with leaderboard ID's as keys and the Top 1 highest score as values NSDictionary *highScores = [[GameCenterManager sharedManager] highScoreForLeaderboards:leaderboardIDs]; So my question is, how can I combine those 2 segments of code to pull in the 100 values for each leaderboard, resulting in a dictionary with all of the leaderboard names as keys, and the Total (of each 100 scores) of the leaderboards for values.

• MySQL connection attempt works fine in 5.2.9 but not in 5.3.0 - Help?

  - by Rich

  Hi, I'm having trouble making a secondary MySQL connection (to a separate, external DB) in my code. It works fine in PHP 5.2.9 but fails to connect in PHP 5.3.0. I'm aware of (at least some) of the changes needed to make successful MySQL connections in the newer version of PHP, and have succeeded before, so I'm not sure why it isn't working this time. I already have a db connection open to a local database. This function below is then used to make an additional connection to a separate, remote directory. The included config file simply contains the external database details (host, user, pass and name). I have checked and it is being included correctly. function connectDP() { global $dpConnection; include("secondary_db_config.php); $dpConnection = mysql_connect($dp_dbHost, $dp_dbUser, $dp_dbPass, true) or DIE("ERROR: Unable to connect to Deployment Platform"); mysql_select_db($dp_dbName, $dpConnection) or DIE("ERROR 006: Unable to select Deployment Platform Database"); } I then attempt to make this new connection simply by calling this function externally: connectDP(); But when loading the page (in 5.3.0), I get the message: ERROR: Unable to connect to Deployment Platform I'm using the optional new_link flag boolean as the fourth argument in the mysql_connect() function and it's still not working. I've been wracking my brain this morning trying to figure out why this connection doesn't work (while I've done something very similar elsewhere to a separate second database that does work). Any help would be appreciated. Thanks! Rich

• Vista seems to prevent .net from reading/updating file attributes.

  - by CFP

  Hello everyone! The following function copies a file from Source & Path to Dest & Path, normally setting file attributes to normal before copying. Yet, a user of my app has reported it to fail when copying readonly files, returning a permissions-related error. The user is however running the code as administrator, and the error happens - quite strangely - on the SetLastWriteTimeUtc line. Although the code reports that the file attributes are set to normal, windows explorer shows that they are set to read only. Sub CopyFile(ByVal Path As String, ByVal Source As String, ByVal Dest As String) If IO.File.Exists(Dest & Path) Then IO.File.SetAttributes(Dest & Path, IO.FileAttributes.Normal) IO.File.Copy(Source & Path, Dest & Path, True) If Handler.GetSetting(ConfigOptions.TimeOffset, "0") <> "0" Then IO.File.SetAttributes(Dest & Path, IO.FileAttributes.Normal) IO.File.SetLastWriteTimeUtc(Dest & Path, IO.File.GetLastWriteTimeUtc(Dest & Path).AddHours(Handler.GetSetting(ConfigOptions.TimeOffset, "0"))) End If IO.File.SetAttributes(Dest & Path, IO.File.GetAttributes(Source & Path)) End Sub I just fail to see the problem in this code, so after long hours of searching for the solution, I thought one of SO VB.Net Gurus might help :) Thanks a lot. Edit: The actual error is Access to the path '(..)' is denied. at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy) at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize) at System.IO.File.OpenFile(String path, FileAccess access, SafeFileHandle& handle) at System.IO.File.SetLastWriteTimeUtc(String path, DateTime lastWriteTimeUtc)

• Trying to join two independent forms

  - by user248959

  Hi, i'm trying to join two independent forms (login and register) in the same page. My idea is (just looking at the signin form): Create an action that shows both forms (partials): public function executeLoginAndRegister(sfWebRequest $request){ $this->form_signin = $this->getUser()->getAttribute('form_signin'); } Each partial calls to its action: form action="php? echo url_for('@sf_guard_signin') ?" method="post" In the actions i write this code public function executeSignin($request) { //... $this->form = new $MyFormclass(); if ($this->form->isValid()) { //... }else{ // save the form to show the error messages. $this-&gt;getUser()-&gt;setAttribute('form_signin', $this-&gt;form); return $this-&gt;forward('sfGuardAuth', 'loginAndRegister'); } } It works, but, for example, if i execute LoginAndRegister and submit incorrectly the signin form and I go to another page and then return to LoginAndRegister, i will find the submiting error messages... If i execute LoginAndRegister and submit incorrectly the signin form and open another browser tab, i will find the submiting error messages in the signin form of the second tab... Any idea? any better approach?

• Salesforce/PHP - outbound messages (SOAP) - memory limit issue? DOMDocument::loadXML() issue?

  - by Phill Pafford

  I'm using Salesforce to send outbound messages (via SOAP) to another server. The server can process about 8 messages at a time, but will not send back the ACK file if the SOAP request contains more than 8 messages. SF can send up to 100 outbound messages in 1 SOAP request and I think this is causing a memory issue with PHP. If I process the outbound messages 1 by 1 they all go through fine, I can even do 8 at a time with no issues. But larger sets are not working. ERROR in SF: org.xml.sax.SAXParseException: Premature end of file Looking in the HTTP error logs I see that the incoming SOAP message looks to be getting cut of which throws a PHP warning stating: DOMDocument::loadXML() ... Premature end of data in tag ... PHP Fatal error: Call to a member function getAttribute() on a non-object This leads me to believe that PHP is having a memory issue and can not parse the incoming message due to it's size. I was thinking I could just set: ini_set('memory_limit', '64M'); // This has done nothing to fix the problem But would this be the correct approach? Is there a way I could set this to increase with the incoming SOAP request dynamically? UPDATE: Adding some code $data = fopen('php://input','rb'); $headers = getallheaders(); $content_length = $headers['Content-Length']; $buffer_length = 1000; $fread_length = $content_length + $buffer_length; $content = fread($data,$fread_length); /** * Parse values from soap string into DOM XML */ $dom = new DOMDocument(); $dom->loadXML($content); ....

• Python script web service timeout

  - by Robert

  We have had a Python script running for many months now that simply scans through a directory of files, and posts each file to our web site via a web service call. The web site is also written in Python. For no apparent reason, this morning this script started throwing the following error: urllib2.URLError: <urlopen error (10060, 'Operation timed out')> The site itself is up and running just fine. There are no indications of any errors. The developer that was working on this site is no longer with us, and we do not have a strong Python developer on staff as we are moving away from that. Before I do an all nighter and rewrite this thing in C#, I wanted to see if anyone had any experience dealing with this issue. I do know that the script is connecting to a secure site (HTTPS), so I am not sure if something has come up with that, and I honestly dont know where to look to determine that. As I said before, the site itself isn't showing any signs of error, including SSL. Any thoughts?

After I launch my app in simulator, it prompts a second, than, no other error except the error above. @implementation MyAppDelegate @synthesize window; @synthesize viewController; - (void)applicationDidFinishLaunching:(UIApplication *)application { // Override point for customization after app launch [window addSubview:viewController.view]; [window makeKeyAndVisible]; [self changeScene:[MainGameMenuScene class]]; } - (void)dealloc { [viewController release]; [window release]; [super dealloc]; } - (void) changeScene: (Class) scene { BOOL animateTransition = true; if(animateTransition){ [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.5]; [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:window cache:YES]; //does nothing without this line. } if( viewController.view != nil ) { [viewController.view removeFromSuperview]; //remove view from window's subviews. [viewController.view release]; //release gamestate } viewController.view = [[scene alloc] initWithFrame:CGRectMake(0, 0, IPHONE_WIDTH, IPHONE_HEIGHT) andManager:self]; //now set our view as visible [window addSubview:viewController.view]; [window makeKeyAndVisible]; if(animateTransition){ [UIView commitAnimations]; } }

• Access to SQL Server 2005 from a non-domain machine using Windows authentication

  - by user304582

  Hi, I have a Windows domain within which a machine is running SQL Server 2005 and which is configured to support only Windows authentication. I would like to run a C# client application on a machine on the same network, but which is NOT on the domain, and access a database on the SQL Server 2005 instance. I thought that it would be a simple matter of doing something like this: string connectionString = "Data Source=server;Initial Catalog=database;User Id=domain\user;Password=password"; SqlConnection connection = new SqlConnection(connectionString); connection.Open(); However, this fails: the client-side error is: System.Data.SqlClient.SqlException: Login failed for user 'domain\user' and the server-side error is: Error 18456, Severity 14, State 5 I have tried various things including setting integrated security to true and false, and \ instead of \ in the User Id, but without success. In general, I know that it possible to connect to the SQL Server 2005 instance from a non-domain machine (for example, I am working with a Linux-based application which happily does this), but I don't seem to be able to work out how to do it from a Windows machine. Help would be appreciated! Thanks, Martin

• AS3 colorTransform over multiple frames?

  - by user359519

  (Flash Professional, AS3) I'm working on a custom avatar system where you can select various festures and colors. For example, I have 10 hairstyles, and a colorPicker to change the color. mc_myAvatar has 10 frames. Each frame has a movieclip of a different hairstyle (HairStyle1, HairStyle2, etc.) Here's my code: var hairColor:ColorTransform; hairColor = mc_myAvatar.hair.colorLayer.transform.colorTransform; hairColor.color = 0xCCCC00; mc_myAvatar.hair.colorLayer.transform.colorTransform = hairColor; This correctly changes the initial color. I have a "nextHair" button to advance mc_myAvatar.hair to the next frame. When I click the button, I get an error message saying that I have a null object reference. I added a trace, and mc_myAvatar.hair.colorLayer is null on frame 2. Why??? I've clearly named HairStyle2 as "colorLayer" in frame 2. I think the problem is related to me using the same name for different classes/movieclips, but I don't know how to fix the problem... I added a square movieclip below my hairStyle movieclips, named the square "colorLevel", and deleted the name from my hairStyle clips. When I click the next button, the square correctly maintains the color from frame to frame. However, having a square doesn't do me much good. :( I tried converting the hairStyle layer to a mask. Doing this, however, results in yet another "null object" error - mc_myAvatar.hair.colorLayer is null after frame 1. I even tried "spanning" my colorLevel across all frames (no keyframes), thinking that this would give me just one movieclip to work with. No luck. Same error! What's going on, here? Why am I getting these null objects, when they are clearly defined in my movieclip? I'm also open to suggestions on a better way to do multiple frames and colors.
