  • cookie not being sent when requesting JS

    - by Mala
    I host a webservice, and provide my members with a Javascript bookmarklet, which loads a JS sript from my server. However, clients must be logged in, in order to receive the JS script. This works for almost everybody. However, some users on setups (i.e. browser/OS) that are known to work for other people have the following problem: when they request the script via the javascript bookmarklet from my server, their cookie from my server does not get included with the request, and as such they are always "not authenticated". I'm making the request in the following way: var myScript = eltCreate('script'); myScript.setAttribute('src','http://myserver.com/script'); document.body.appendChild(myScript); In a fit of confused desperation, I changed the script page to simply output "My cookie has [x] elements" where [x] is count($_COOKIE). If this extremely small subset of users requests the script via the normal method, the message reads "My cookie has 0 elements". When they access the URL directly in their browser, the message reads "My cookie has 7 elements". What on earth could be going on?!

  • Running a cronjob

    - by Ed01
    've been puzzling over cronjobs for the last few hours. I've read documentation and examples. I understand the basics and concepts, but haven't gotten anything to work. So I would appreciate some help with this total noob dilemma. The ultimate goal is to schedule the execution of a django function every day. Before I get that far, I want to know that I can schedule any old script to run, first once, then on a regular basis. So I want to: 1) Write a simple script (perhaps a bash script) that will allow me to determine that yes, it did indeed run successfully, or that it failed. 2) schedule this script to run at the top of the hour I tried writing a bash script that simple output some text to the terminal: #!/bin/bash echo "The script ran" Then I dropped this into a .txt file MAILTO = *****.******@gmail.com 05 * * * * /home/vadmin/development/test.sh But nothing happened. I'm sure I did many things wrong. Where do I start to fix all of this?

  • How to change TXSDateTime SOAP serialization in Delphi 7?

    - by LukLed
    I am trying to use Java based webservice and have soap request: <?xml version="1.0"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"> <SOAP-ENV:Body xmlns:NS1="http://something/"> <NS1:getRequest id="1"> <sessionId xsi:type="xsd:string"></sessionId> <reportType xsi:type="NS1:reportType">ALL</reportType> <xsd:dateFrom xsi:type="xsd:dateTime">2010-05-30T23:29:43.088+02:00</xsd:dateFrom> <xsd:dateTo xsi:type="xsd:dateTime">2010-05-31T23:29:43.728+02:00</xsd:dateTo> </NS1:getRequest> <parameters href="#1" /> </SOAP-ENV:Body> </SOAP-ENV:Envelope> It doesn't work, because webservice doesn't recognize dates as parameters. When I change <xsd:dateFrom xsi:type="xsd:dateTime">2010-05-30T23:29:43.088+02:00</xsd:dateFrom> <xsd:dateTo xsi:type="xsd:dateTime">2010-05-31T23:29:43.728+02:00</xsd:dateTo> to <dateFrom xsi:type="xsd:dateTime">2010-05-30T23:29:43.088+02:00</xsd:dateFrom> <dateTo xsi:type="xsd:dateTime">2010-05-31T23:29:43.728+02:00</xsd:dateTo> everything works ok, but Delphi (without Delphi source code changes) doesn't allow to change generated XML, it has only some options. Is it possible to set conversion options, so TSXDateTime is converted to <dateFrom, not <xsd:dateFrom tag? Did you meet that problem?

  • Simple jquery ajax call leaks memory in ie.

    - by Thomas Lane
    I created a web page that makes an ajax call every second. In Internet Explorer 7, it leaks memory badly (20MB in about 15 minutes). The program is very simple. It just runs a javascript function that makes an ajax call. The server returns an empty string, and the javascript does nothing with it. I use setTimout to run the function every second, and I'm using Drip to watch the thing. Here is the source: <html> <head> <script type="text/javascript" src="http://www.google.com/jsapi"></script> <script type="text/javascript"> google.load('jquery', '1.4.2'); google.load('jqueryui', '1.7.2'); </script> <script type="text/javascript"> setTimeout('testJunk()',1000); function testJunk() { $.ajax({ url: 'http://xxxxxxxxxxxxxx/test', // The url returns an empty string dataType: 'html', success: function(data){} }); setTimeout('testJunk()',1000) } </script> </head> <body> Why is memory usage going up? </body> </html> Anyone have an idea how to plug this leak? I have a real application that updates a large table this way, but left unattended will eat up Gigabytes of memory. Okay, so after some good suggestions, I modified the code to: <html> <head> <script type="text/javascript" src="http://www.google.com/jsapi"></script> <script type="text/javascript"> google.load('jquery', '1.4.2'); google.load('jqueryui', '1.7.2'); </script> <script type="text/javascript"> setTimeout(testJunk,1000); function testJunk() { $.ajax({ url: 'http://xxxxxxxxxxxxxx/test', // The url returns an empty string dataType: 'html', success: function(data){setTimeout(testJunk,1000)} }); } </script> </head> <body> Why is memory usage going up? </body> </html> It didn't seem to make any difference though. I'm not doing anything with the DOM, and if I comment out the ajax call, the memory leak stops. So it looks like the leak is entirely in the ajax call. Does jquery ajax inherently create some sort of circular reference, and if so, how can I free it? By the way, it doesn't leak in Firefox. Someone suggested running the test in another VM and see if the results are the same. Rather than setting up another VM, I found a laptop that was running XP Home with IE8. It exhibits the same problem. I tried some older versions of jquery and got better results, but the problem didn't go away entirely until I abandoned ajax in jquery and went with more traditional (and ugly) ajax.

  • iphone app scroll view is horizontal but i want it vertical - how do i change this?

    - by Billy Jones
    Hi Folks, Got this code for a viewscroller from the apple developers site. @synthesize scrollView1, scrollView2; const CGFloat kScrollObjHeight = 467.0; const CGFloat kScrollObjWidth = 320.0; const NSUInteger kNumImages = 6; (void)layoutScrollImages { UIImageView *view = nil; NSArray *subviews = [scrollView1 subviews]; // reposition all image subviews in a horizontal serial fashion CGFloat curXLoc = 0; for (view in subviews) { if ([view isKindOfClass:[UIImageView class]] && view.tag 0) { CGRect frame = view.frame; frame.origin = CGPointMake(curXLoc, 0); view.frame = frame; curXLoc += (kScrollObjWidth); } } // set the content size so it can be scrollable [scrollView1 setContentSize:CGSizeMake((kNumImages * kScrollObjWidth), [scrollView1 bounds].size.height)]; } it works brilliantly the images are rotated by pulling them left or right. but I want to pull the images up and down to change them. Can anyone help me out with this? this part in the code looks as if it controls the direction but i'm not sure how to change it. // reposition all image subviews in a horizontal serial fashion CGFloat curXLoc = 0; for (view in subviews) { if ([view isKindOfClass:[UIImageView class]] && view.tag 0) { CGRect frame = view.frame; frame.origin = CGPointMake(curXLoc, 0); view.frame = frame; curXLoc += (kScrollObjWidth); } } Any help most appreciated, thanks!

  • How to change disclosure style when user enters in edit mode of a UITableView?

    - by R31n4ld0
    Hello, guys. I have a UITableView that in 'normal' mode, show a UITableViewCellAccessoryDisclosureIndicator meaning if the user taps the row, another list is showed, like HIG says: "Disclosure indicator. When this element is present, users know they can tap anywhere in the row to see the next level in the hierarchy or the choices associated with the list item. Use a disclosure indicator in a row when selecting the row results in the display of another list. Don’t use a disclosure indicator to reveal detailed information about the list item; instead, use a detail disclosure button for this purpose." When the user tap the edit button in the top bar of the UITableView, I think I have to change the disclosure because if the user tap it, a view for changing the information of the current row is showed (see the bold line above), again, like HIG says: "Detail disclosure button. Users tap this element to see detailed information about the list item. (Note that you can use this element in views other than table views, to reveal additional details about something; see “Detail Disclosure Buttons” for more information.) In a table view, use a detail disclosure button in a row to display details about the list item. Note that the detail disclosure button, unlike the disclosure indicator, can perform an action that is separate from the selection of the row. For example, in Phone Favorites, tapping the row initiates a call to the contact; tapping the detail disclosure button in the row reveals more information about the contact." Have I miss understood the HIG, or I really do have to change the disclosure style in edit mode of UITableView? If yes, how I can intercept the edit mode when the user taps the Edit button? Thanks in advance.

  • Eclipse - How can I change a 'Project Facet' from Tomcat 6 to Tomcat 5.5?

    - by pcimring
    (Eclipse 3.4, Ganymede) I have an existing Dynamic Web Application project in Eclipse. When I created the project, I specified 'Default configuration for Apache Tomcat v6' under the 'Configuration' drop down. It's a month or 2 down the line, and I would now like to change the configuration to Tomcat 'v5.5'. (This will be the version of Tomcat on the production server.) I have tried the following steps (without success): I selected Targeted Runtimes under the Project Properties The Tomcat v5.5 option was disabled and The UI displayed this message: If the runtime you want to select is not displayed or is disabled you may need to uninstall one or more of the currently installed project facets. I then clicked on the Uninstall Facets... link. Under the Runtimes tab, only Tomcat 6 displayed. For Dynamic Web Module, I selected version 2.4 in place of 2.5. Under the Runtimes tab, Tomcat 5.5 now displayed. However, the UI now displayed this message: Cannot change version of project facet Dynamic Web Module to 2.4. The Finish button was disabled - so I reached a dead-end. I CAN successfully create a NEW Project with a Tomcat v5.5 configuration. For some reason, though, it will not let me downgrade' an existing Project. As a work-around, I created a new Project and copied the source files from the old Project. Nonetheless, the work-around was fairly painful and somewhat clumsy. Can anyone explain how I can 'downgrade' the Project configuration from 'Tomcat 6' to 'Tomcat 5'? Or perhaps shed some light on why this happened? Thanks Pete

  • How do I change the spacing between fields in a DataForm?

    - by Simon_Weaver
    How do I change the spacing between fields in a DataForm in Silverlight? I've tried editing the template but cannot find what I need. I thought all I needed to do was change the MinHeight and Margin of the DataField style, but that doesn't seem to do it. <Style TargetType="dataFormToolkit:DataField"> <Setter Property="IsTabStop" Value="False"/> <Setter Property="Margin" Value="2"/> <Setter Property="MinHeight" Value="5"/> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="dataFormToolkit:DataField"> <ContentControl x:Name="ContentControl" Foreground="{TemplateBinding Foreground}" HorizontalContentAlignment="Stretch" IsTabStop="False" VerticalAlignment="Center"/> </ControlTemplate> </Setter.Value> </Setter> </Style> I've found a number of articles about styling DataForm but many of them seem to be out of date. I don't see anything in the complete extracted template in Blend that corresponds to spacing.

  • How can I change the text in a <span></span> element using jQuery?

    - by Eric Reynolds
    I have a span element as follows: <span id="download">Download</span>. This element is controlled by a few radio buttons. Basically, what I want to do is have 1 button to download the item selected by the radio buttons, but am looking to make it a little more "flashy" by changing the text inside the <span> to say more specifically what they are downloading. The span is the downloading button, and I have it animated so that the span calls slideUp(), then should change the text, then return by slideDown().Here is the code I am using that does not want to work. $("input[name=method]").change(function() { if($("input[name=method]").val() == 'installer') { $('#download').slideUp(500); $('#download').removeClass("downloadRequest").removeClass("styling").css({"cursor":"default"}); $('#download').text("Download"); $('#download').addClass("downloadRequest").addClass("styling").css({"cursor":"pointer"}); $('#download').slideDown(500); } else if($("input[name=method]").val() == 'url') { $('#download').slideUp(500); $('#download').removeClass("downloadRequest").removeClass("styling").css({"cursor":"default"}); $('#download').text("Download From Vendor Website"); $('#download').addClass("styling").addClass("downloadRequest").css({"cursor":"pointer"}); $('#download').slideDown(500); } }); I changed the code a bit to be more readable so I know that it doesn't have the short code that jQuery so eloquently allows. Everything in the code works, with the exception of the changing of the text inside the span. I'm sure its a simple solution that I am just overlooking. Any help is appreciated, Eric R.

  • Unable to change the system zone setting on Windows Server 2008 R2.

    - by Ganesh
    Hi All, I have an MFC application that tries to change the system zone setting on the Windows Server 2008 R2. I am using the SetTimeZoneInformation() API which fails with the error code 1314 .i.e. “A required privilege is not held by the client.”. Please refer the sample code below: TIME_ZONE_INFORMATION l_TimeZoneInfo; DWORD l_dwRetVal = 0; ZeroMemory(&l_TimeZoneInfo, sizeof(TIME_ZONE_INFORMATION)); l_TimeZoneInfo.Bias = -330; l_TimeZoneInfo.StandardBias = 0; l_TimeZoneInfo.StandardDate.wDay = 0; l_TimeZoneInfo.StandardDate.wDayOfWeek = 0; l_TimeZoneInfo.StandardDate.wHour = 0; l_TimeZoneInfo.StandardDate.wMilliseconds = 0; l_TimeZoneInfo.StandardDate.wMinute = 0; l_TimeZoneInfo.StandardDate.wMonth = 0; l_TimeZoneInfo.StandardDate.wSecond = 0; l_TimeZoneInfo.StandardDate.wYear = 0; CString l_csDaylightName = _T("India Daylight Time"); CString l_csStdName = _T("India Standard Time"); wcscpy(l_TimeZoneInfo.DaylightName,l_csDaylightName.GetBuffer(l_csDaylightName.GetLength())); wcscpy(l_TimeZoneInfo.StandardName,l_csStdName.GetBuffer(l_csStdName.GetLength())); ::SetLastError(0); if(0 == ::SetTimeZoneInformation(&l_TimeZoneInfo)) { l_dwRetVal = ::GetLastError(); CString l_csErr = _T(""); l_csErr.Format(_T("%d"),l_dwRetVal); } The MFC application has been developed using Visual Studio 2008 and is UAC aware i.e. the application has UAC enabled in its manifest file with the UAC execution level set to “HighestAvailable”. I have administrator privileges and when I run the application it still fails to change the system zone setting. Thanks in Advance, Ganesh

When I call the html page then .js file also included. In the .js,I am using $('div').live('pageshow',function(){}). I am calling the html file from the .js(using $.mobile.changePage("htmlpage")). My problem : consider, I have two html files. second.html file is called with in the one.js. when I show the second.html, that time one.js is reload again. I am getting the alert "one.js" then "second.js" Please help me. Thanks in advance. Please point out my mistake.

  • How can we change views in a UISplitViewController other than using the popover and selecting?

    - by wolverine
    I have done a sample app with UISplitViewController studying the example they have provided. I have created three detailviews and have configured them to change by the default means. Either using the left/master view in landscape AND using the popover in the portrait orientation. Now I am trying to move to another view(previous/next) from the currentView by using left/right swipe in each view. For that, what I did was just created a function in the RootViewController. I copy-pasted the same code as that of the tablerow selection used by the popover from the RootViewController. I am calling this function from my current view's controller and is passing the respective index of the view(to be displayed next) from the current view. Function is being called but nothing is happening. Plz help me OR is anyother way to do it other than this complex step? I am giving the function that I used to change the view. - (void) rearrangeViews:(int)viewRow { UIViewController <SubstitutableDetailViewController> *detailViewController = nil; if (viewRow == 0) { DetailViewController *newDetailViewController = [[DetailViewController alloc] initWithNibName:@"DetailView" bundle:nil]; detailViewController = newDetailViewController; } if (viewRow == 1) { SecondDetailViewController *newDetailViewController = [[SecondDetailViewController alloc] initWithNibName:@"SecondDetailView" bundle:nil]; detailViewController = newDetailViewController; } if (viewRow == 2) { ThirdDetailViewController *newDetailViewController = [[ThirdDetailViewController alloc] initWithNibName:@"ThirdDetailView" bundle:nil]; detailViewController = newDetailViewController; } // Update the split view controller's view controllers array. NSArray *viewControllers = [[NSArray alloc] initWithObjects:self.navigationController, detailViewController, nil]; splitViewController.viewControllers = viewControllers; [viewControllers release]; if (rootPopoverButtonItem != nil) { [detailViewController showRootPopoverButtonItem:self.rootPopoverButtonItem]; } [detailViewController release]; }

  • ScriptManager emits ScriptReferences after ClientScriptIncludes. Why?

    - by Chris F
    I have an application that uses a lot of javascript in a lot of different .js files. Each page can have any number and combination of different controls and each control can use a different set of js files. Instead of including all possible js files as <script src="xxx.js"> in the head of my master page, I thought I would reduce the amount of included files by getting each control to call ScriptManager.Scripts.Add(new ScriptReference("xxx.js")) - thus only the scripts that are actually needed by the page will be included. Well that bit works fine. But...the controls also use ScriptManager.RegisterClientScriptBlock fairly extensively too. (There are scenarios where the controls are inside update panels). I was disappointed to see that the ScriptManager emits the client script includes before the ScriptReferences. For example - see the test file and output at the end (this results in a JS error because $ is not defined). Am I being dumb or is this to be expected? I would have thought that a sensible thing for the ScriptManger to do would be to emit the ScriptReferences first and then the other stuff. Short of rolling my own ScriptManager like object to manage static JS file references, does anyone have any suggestions as to get the behaviour that I want from ScriptManager?? Thanks in advance.

  • JavaFX 2.0 - How to change legend color of a LineChart dynamically?

    - by marie
    I am trying to style my JavaFX linechart but I have some trouble with the legend. I know how to change the legend color of a line chart in the css file: .default-color0.chart-series-line { -fx-stroke: #FF0000, white; } .default-color1.chart-series-line { -fx-stroke: #00FF00, white; } .default-color2.chart-series-line { -fx-stroke: #0000FF, white; } .default-color0.chart-line-symbol { -fx-background-color: #FF0000, white; } .default-color1.chart-line-symbol { -fx-background-color: #00FF00, white; } .default-color2.chart-line-symbol { -fx-background-color: #0000FF, white; } But this is not enough for my purposes. I have three or more colored toggle buttons and a series of data for every button. The data should be displayed in the same color the button has after I have selected the button. This should be possible with a multiselection of the buttons, so that more than one series of data can be displayed simultaneously. For the chart lines I have managed it by changing the style after I clicked the button: .. dataList.add(series); .. series.getNode().setStyle("-fx-stroke: rgba(" + rgba + ")"); If I deselect the button I remove the data from the list. dataList.remove(series); That is working fine for the strokes, but how can I do the same for the legend? You can see an example below. First I clicked the red button, thus the stroke and the legend is red (default-color0). After that I clicked the blue button. Here you can see the problem. The stroke is blue but the legend is green, because default color1 is used and I do not know how to change the legend color.

  • Number of simple mutations to change one string to another?

    - by mstksg
    Hi; I'm sure you've all heard of the "Word game", where you try to change one word to another by changing one letter at a time, and only going through valid English words. I'm trying to implement an A* Algorithm to solve it (just to flesh out my understanding of A*) and one of the things that is needed is a minimum-distance heuristic. That is, the minimum number of one of these three mutations that can turn an arbitrary string a into another string b: 1) Change one letter for another 2) Add one letter at a spot before or after any letter 3) Remove any letter Examples aabca => abaca: aabca abca abaca = 2 abcdebf => bgabf: abcdebf bcdebf bcdbf bgdbf bgabf = 4 I've tried many algorithms out; I can't seem to find one that gives the actual answer every time. In fact, sometimes I'm not sure if even my human reasoning is finding the best answer. Does anyone know any algorithm for such purpose? Or maybe can help me find one? Thanks.

  • How to change the UIImageView image content by code?

    - by Tattat
    I use this to assign image: UIImage *img = [UIImage imageWithContentsOfFile: [[NSBundle mainBundle] pathForResource:@"myImage" ofType:@"png"]]; CGRect cropRect = CGRectMake(175, 0, 175, 175); CGImageRef imageRef = CGImageCreateWithImageInRect([img CGImage], cropRect); imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 175, 175)]; imageView.image = [UIImage imageWithCGImage:imageRef]; [self addSubview:imageView]; CGImageRelease(imageRef); Now, I want to change the image from myImage to myImage2, so I do that: UIImage *img = [UIImage imageWithContentsOfFile: [[NSBundle mainBundle] pathForResource:@"myImage2" ofType:@"png"]]; CGRect cropRect = CGRectMake(175, 0, 175, 175); CGImageRef imageRef = CGImageCreateWithImageInRect([img CGImage], cropRect); imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 175, 175)]; imageView.image = [UIImage imageWithCGImage:imageRef]; [self addSubview:imageView]; It works, but not the way I want, I want to change the image, not add a imageView on top of the pervious one. How can I modify my code? thx u.

  • GlassFish 3: how do you change the (default) logging format?

    - by Kawu
    The question originated from here: http://www.java.net/forum/topic/glassfish/glassfish/configuring-glassfish-logging-format - without an answer. The default GlassFish 3 logging format of is very annoying, much too long. [#|2012-03-02T09:22:03.165+0100|SEVERE|glassfish3.1.2|javax.enterprise.system.std.com.sun.enterprise.server.logging|_ThreadID=113;_ThreadName=AWT-EventQueue-0;| MESSAGE... ] This is just a horrible default IMO. The docs just explain all the fields, but not how to change the format: http://docs.oracle.com/cd/E18930_01/html/821-2416/abluk.html Note, that I deploy SLF4J along with my webapp which should pick up the format as well. How do you change the logging format? FYI: The links here are outdated: Install log formater in glassfish... The question here hasn't been answered: How to configure GlassFish logging to show milliseconds in timestamps?... The posting here resulted in nothing: http://www.java.net/forum/topic/glassfish/glassfish/cant-seem-configure-... It looks like GlassFish logging configuration is an issue of its own. Can anybody help?

  • Events do not propagate from a child element?

    - by Legend
    I was playing around with the Swipe jQuery plugin on my iPod Touch and Android devices. The following works: <html> <head> <script type="text/javascript" src="lib/jquery/jquery-1.3.2.js"></script> <script type="text/javascript" src="lib/plugins/jquery.swipe.js"></script> <script type="text/javascript"> $(function() { $('body').swipe({ swipeLeft: function() { $('#container1').append("Swiped Left!"); }, swipeRight: function() { $('#container2').append("Swiped Right!");} }); }); </script> <style type="text/javascript"> body {width: 300px; height: 300px; background: #000;} </style> </head> <body> <div id="container1"> This is container one </div> <div id="container2"> This is container two </div> </body> </html> But if I have something like this: <html> <head> <script type="text/javascript" src="lib/jquery/jquery-1.3.2.js"></script> <script type="text/javascript" src="lib/plugins/jquery.swipe.js"></script> <script type="text/javascript"> $(function() { $('#wrapper').swipe({ swipeLeft: function() { $('#container1').append("Swiped Left!"); }, swipeRight: function() { $('#container2').append("Swiped Right!");} }); }); </script> <style type="text/javascript"> body {width: 300px; height: 300px; background: #000;} </style> </head> <body> <div id="wrapper"> <div id="container1"> This is container one </div> <div id="container2"> This is container two </div> </div> </body> </html> Notice the "wrapper" div around the containers. Now, when I swipe on the div element, I was expecting it to actually trigger the event. This works in iPod touch as expected but does not work on my Android device unless I randomly start swiping everywhere until I happen to swipe on that small wrapper div element itself. I am not sure how to explain this but hink of it as sending events to the wrapper div itself. Both use the WebKit engine. Can someone tell me if I am doing something wrong?

  • I have created a PHP script and I am lacking to extract the primary key, I have given flow below, pl

    - by Parth
    I am using MySQL DB, working for Joomla, My requirement is tracking the activity like insert/update/delete on any table and store it in another audit table using triggers, i.e. I am doing Auditing. DB's table structure: Few tables dont have any PK nor auto increment key Flow of my script is : I fetch out all table from DB. I check whether the table have any trigger or not. If yes then it moves to check nfor next table and so on. If it does'nt find any trigger then it creates the triggers for the table, such that, -it first checks if the table has any primary key or not(for inserting in Tracking audit table for every change made) if it has the primary key then it uses it further in creation of trigger. if it doesnt find any PK then it proceeds further in creating the trigger without inserting any id in audit table Now here, My problem is I need the PK every time so that I can record the id of any particular table in which the insert/update/delete is performed, so that further i can use this audit track table to replicate in production DB.. Now as I haave mentioned earlier that I am not available with PK/auto-incremented in some table, then what should I do get the particular id in which change is done? please guide me...GEEKS!!!

  • SPSS - sum of squares change radically with slight model changes in ANOVA??

    - by Pat
    I have noticed that the sum of squares in my models can change fairly radically with even the slightest adjustment to my models???? Is this normal???? I'm using SPSS 16, and both models presented below used the same data and variables with only one small change - categorizing one of the variables as either a 2 level or 3 level variable. Details - using a 2 x 2 x 6 mixed model ANOVA with the 6 being the repeated measure i get the following in the between group analysis ------------------------------------------------------------ Source | Type III SS | df | MS | F | Sig ------------------------------------------------------------ intercept | 4086.46 | 1 | 4086.46 | 104.93 | .000 X | 224.61 | 1 | 224.61 | 5.77 | .019 Y | 2.60 | 1 | 2.60 | .07 | .80 X by Y | 19.25 | 1 | 19.25 | .49 | .49 Error | 2570.40 | 66 | 38.95 | Then, when I use the exact same data but a slightly different model in which variable Y has 3 levels instead of 2 levels I get the following ------------------------------------------------------------ Source | Type III SS | df | MS | F | Sig ------------------------------------------------------------ intercept | 3603.88 | 1 | 3603.88 | 90.89 | .000 X | 171.89 | 1 | 171.89 | 4.34 | .041 Y | 19.23 | 2 | 9.62 | .24 | .79 X by Y | 17.90 | 2 | 17.90 | .80 | .80 Error | 2537.76 | 64 | 39.65 | I don't understand why variable X would have a different sum of squares simply because variable Y gets devided up into 3 levels instead of 2. This is also the case in the within groups analysis too. Please help me understand :D Thank you in advance Pat

  • How do I change the application background color at run-time in a Flex 3.5 application?

    - by Adam Tuttle
    I have a Flex 3.5 application that will serve multiple purposes, and as part of the visual changes that I'd like to make to indicate which mode the application is in, I want to change its background color. Currently, the application tag looks like this: <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" xmlns:com="ventures.view.component.*" xmlns:views="ventures.view.*" layout="absolute" preinitialize="onPreInitialize()" creationComplete="onCreationComplete()" applicationComplete="onApplicationComplete()" click="onClick(event)" enabled="{(!chainController.generalLocked)}" backgroundGradientColors="[0xFFFFFF, 0xFFFFFF]" > I've tried using a binding, for both the backgroundColor and backgroundGradientColors attributes: <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" ... backgroundColor="{app_background_color}" > —and— <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" ... backgroundGradientColors="{app_background_color}" > but for the former binding is not allowed, and for the latter there is a warning that: Data binding will not be able to detect assignments to "app_background_color". I also ran across this page which seems to indicate that I could do it with the setStyle() method, but the documentation seems to indicate that this method is only available for components, not the main canvas. I suppose I could wrap everything in a <mx:Canvas></mx:Canvas> specificially for this purpose, but that seems wasteful—like Div-itis in HTML or something. What's the best way to change the main application background color at run-time?

  • Layout: how to make image to change its width and height proportionally?

    - by Exterminator13
    I have such layout: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="horizontal"> <TextView android:id="@+id/title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:layout_centerVertical="true" android:layout_toLeftOf="@+id/my_image" android:ellipsize="end" android:singleLine="true" android:text="Some text" android:textAppearance="?android:attr/textAppearanceMedium" /> <ImageView android:id="@+id/my_image" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignTop="@+id/title" android:layout_alignBottom="@+id/title" android:layout_alignParentRight="true" android:layout_centerVertical="true" android:adjustViewBounds="true" android:src="@drawable/my_bitmap_image" /> This layout does almost what I need: it makes image view height the same as text view. The image graphic contents stretched also keeping aspect ratio. But, the width of the image view does not change! As a result, I have a wide gap between text and the image view! As a temporal solution, I override View#onLayout. The question: how to change image width in xml layout? UPDATE: This is a final layout I need (text + a few images). Look at the first image: its width should be exactly the same as scaled image in it with no paddings and margins:
