  • IE display problem

    - by bah
    Hi, I have a page, and I just added pagination to it, but there's a prob in IE 7 & 8. When I add pagination code echo "<div class='pagination'>"; echo $pagination->GetPageLinks(); echo "</div>"; it breaks somehow layout in IE, I have looked all over it and I couldn't find what's wrong there. oh, and its css div.pagination { text-align : center; } div.pagination a, div.pagination span { padding : 5px; display : inline-block; } page url - adelija.puslapiai.lt, it's on index page, if you could take a look, that'd be great.

  • reStructuredText for SQL?

    - by Chris
    I am trying to use DocUtils and reStructuredText to comment SQL code. I can get this to work when I include the markup inside multi-line comments. I then use --Some text:: to introduce each block of code. I cannot get internal hyperlinks to work. I would like to write -- .. Step1_: but the parser ignores this because of the leading comment. Using a multi-line style also fails. Is there a way to get this to work? Here's an example: /* ========== this query ========== :Author: Me Outline ========== - Create table 1 - Create table 2 - Output the result */ -- _Step1: build the table:: create table table1 -- _Step2: use Step1_ to build table 2:: create table table2

  • Running out of memory when getting a bitmap from a server?

    - by ikky
    Hi! I'm making an application which uses MANY images. The application gets the images from a server, and downloads them one at a time. After many images the creation of a bitmap returns an exception, but i don't know how to solve this. Here is my function for downloading the images: public static Bitmap getImageFromWholeURL(String sURL) { HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(sURL); myRequest.Method = "GET"; // If it does not exist anything on the url, then return null try { HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse(); System.Drawing.Bitmap bmp = new System.Drawing.Bitmap(myResponse.GetResponseStream()); myResponse.Close(); return bmp; } catch (Exception e) { return null; } } Can anyone help me out here? Thanks in advance!

  • Correct Exceptions in C++

    - by Dr.Ackula
    I am just learning how to handle errors in my C++ code. I wrote this example that looks for a text file called some file, and if its not found will throw an exception. #include <iostream> #include <fstream> using namespace std; int main() { int array[90]; try { ifstream file; file.open("somefile.txt"); if(!file.good()) throw 56; } catch(int e) { cout<<"Error number "<<e<<endl; } return 0; } Now I have two questions. First I would like to know if I am using Exceptions correctly. Second, (assuming the first is true) what is the benefit to using them vs an If else statement?

  • Thread Code...anything wrong with this, must use java 1.4

    - by bmw0128
    I have a servlet automatically firing up when the app server starts, and in its init(), I'm making another thread: init(){ new FooThread() } in FooThread(), i want to periodically check the status of a DB value, then depending on the value, make a web service call. When these two tasks complete, I want the thread to sleep to wait a certain period then repeat. This cycle would just continue forever. FooThread: public class FooThread implements Runnable{ Thread t; FooThread(){ t = new Thread(this, "BBSThread"); logger.info("*** about to start " + t.getName()); t.start(); logger.info("*** started: " + t); } public void run() { try{ while(true){ //do the db check, then conditionally do the web services call logger.info("*** calling sleep() ***"); Thread.sleep(50000); logger.info("*** now awake ***"); } } catch (InterruptedException e) { System.out.println("*** FooThread interrupted"); } } }

  • How to display icons next to a select1 control with xxforms:tree appearance

    - by user557060
    Hi, I display a list of items via select1 control using xxforms:tree appearance. They are displayed via a code block like: <xforms:itemset nodeset="instance('dataInstance')/*"> <xforms:label ref="fn:concat(./NAME,', ','ID: ',./ID)"/> <xforms:value ref="./ID"/> </xforms:itemset> </xforms:select1> I want to display two icons for each item on the same row as the item: one icon for deleting and one for editing that item, which would all invoke XPL with the item ID as the parameter. The question, how do I render those icons - does itemset support nested trigger elements? If not, how do I go about achieving it (clicking on the item results in an action other than edit or delete, so cannot use that; can show delete/edit on the page shown when user clicks on the item, but want to save that one click if the user just wants to delete the item for example). Thanks.

  • How do I stop a jquery animation based on CSS values?

    - by kevn
    So, I have two divs: #div1 and #div2. I want '#div2' to disappear when '#div1' has the CSS value: top = 0px. Here is the CSS: #div1 { top: 0px; } #div2 { display: block; } if ( $('#div1').css('top') == '0px' ) { $("#div2").hide(); } else { $("div2").fadeIn(); } $("div2").click(function(){ $("#div1").animate({top:"+=315px"}, "slow"); }); The problem I am running into is that I'm changing that CSS value (for #div1) via Javascript and for this reason, my js doesn't acknowledge the change and doesn't make the div disappear (I think). Is there any way to make #div2 disappear when #div1's CSS property top = 0 and reappear whenever it is changed? Or is there a better way to implement this?

  • How to continue copying on error with copyDirectory from FileUtils (Apache Commons IO 2.4)

    - by Exocom
    I am trying to copy files from one folder to another using the FileUtils method "static void copyDirectory(File srcDir, File destDir)" from apache commons io (2.4) with the following code: String srcDir = "/sourceDirectory/examples/"; String destDir = "/tmp/examples/"; try{ FileUtils.copyDirectory(new File(srcDir), new File(destDir)); } catch (IOException e){ e.printStackTrace(); } The file structure looks like the following: examples/ (read access) examples/.subdirectory (NO access) examples/file1.txt (read access) examples/file2.txt (read access) examples/subdirectory2/file1.txt (read access) examples/subdirectory2/file2.txt (NO access) The problem is, that in srcDir there are a few files and one subdirectory I don't have access to. FileUtils.copyDirectory throws an "java.io.FileNotFoundException: .subdirectory (Permission denied)" and aborts. Is it possible to ignore those files I don't have permission to and just copy all the other files I can read?

  • IE7 and the CSS table-cell property

    - by Ryan Smith
    So I just love it when my application is working great in Firefox, but then I open it in IE and... Nope, please try again. The issue I'm having is that I'm setting a CSS display property to either "none" or "table-cell" with JavaScript. I was initially using "display: block;", but Firefox was rending it weird without the table-cell property. I would love to do this without adding an hack in the JavaScript to test for IE. Any suggestions? Thanks.

  • 3 div independently relative and top aligned

    - by Knu
    I have 3 div top aligned that should be relative to a previous div (not between them so i can't use floats or position:inline-block either). If you set display:none on 2 divs the last one shouldn't move. I can't use position:absolute because there's a relative footer underneath. I tried using a wrapper but it can't work cause the height of the divs is not fixed. The height of the wrapper gets completely ignored anyway (by the following footer) unless Im using relative children. vertical-align:top doesn't work either. Any ideas?

  • Setting location based on previous parameter of $routeChangeError with AngularJS

    - by Moo
    I'm listening on events of the type $routeChangeError in a run block of my application. $rootScope.$on("$routeChangeError", function (event, current, previous, rejection) { if (!!previous) { console.log(previous); $location.path(previous.$$route.originalPath); } }); With the help of the previous parameter I would like to set the location to the previous page. This works as long as the "originalPath" of "previous.$$route" does not contain any parameters. If it contains parameters the "originalPath" is not transformed. Logging the previous objects returns the following output: $$route: Object ... originalPath: "/users/:id" regexp: /^\/users\/(?:([^\/]+)?)$/ ... params: Object id: "3" How can I set the location to the previous path including the parameters?

  • Unity 2.0. How to throw ResolutionFailedException

    - by Andrey Khataev
    Hello, I have my app, using functionality that is based on unity application block. Sometimes I need to throw ResolutionFailedException manually. In v1.2 constructor of ResolutionFailedException had three parameters - typerequested, namerequested and exception. In v2.0 fourth parameter was added - buildercontext. I'm not creating it manually, so I have no reference to it and no idea where I can get it. Roughly speaking, I'm only overriding Resolve method in particular way and I'm not interfere in standard mechanism of policies, strategies and so on. Could anyone help?

  • Automatic Step over

    - by Vaccano
    I have been getting this error message when I step into some methods Do you want to continue being notified when an Automatic step over occurs? I usually answer Yes and I get taken to the line I want to step to. However, I just pressed No (cause I was tired of the dialog box always popping up). When I did that it skipped a lot of code I wanted to step through. Now when I step into my method it is skipping my method (and jumping to the finally block because the method I am trying to step into is throwing an exception). How can I change my answer back to Yes? I would prefer it never ask me (default showing the code), but if faced with the choice of it skipping the code I need to see, or having a NagBox, I will take the NagBox.

  • iPhone animation with stretchable image

    - by ryyst
    I got a UIView subclass that draws a UIImage as its background. The image is created using the stretchableImageWithLeftCapWidth:topCapHeight: method, it has round edges. I also use an animation block inside of which I resize my view. I had hoped that during animation, the drawRect:method would get called sometimes, which would result in the background image getting drawn correctly. Unfortunately, the animation seems to render the image and then just rescale it during the animation, which obviously makes the formerly round edges getting nastily stretched. The only workaround I can imagine is put three separate UIImageViews (top cap, middle fill, bottom cap) above my original background image and then reposition the caps images and scaling the fill image. However, this seems quite complicated... Is there any better way I can prevent this from happening?

  • How to know when the user touches the OK button of the last StoreKit alert "Thank you. Your purchase

    - by Walchy
    I have integrated "In App Purchase" in a game to let the user unlock more levels. Everything works fine, but I have a little problem with the last alert "Thank You. Your purchase was successful. [OK]". My program gets informed that the transaction was successfully completed before this last alert pops up and so my game starts running again - then the alert comes up, annoying the user. I would like to wait with my game running until the user touches the "OK" button, but since it is an alert from StoreKit I have no idea when this happens or how I could catch it. I don't want to create another dialog (this time my own, therefor under my control) below the alert, just asking for touching "OK" again - would be a bad user experience. Anybody have any ideas?

  • Maintaining Logging and/or stdout/stderr in Python Daemon

    - by dave mankoff
    Every recipe that I've found for creating a daemon process in Python involves forking twice (for Unix) and then closing all open file descriptors. (See http://www.jejik.com/articles/2007/02/a_simple_unix_linux_daemon_in_python/ for an example). This is all simple enough but I seem to have an issue. On the production machine that I am setting up, my daemon is aborting - silently since all open file descriptors were closed. I am having a tricky time debugging the issue currently and am wondering what the proper way to catch and log these errors are. What is the right way to setup logging such that it continues to work after daemonizing? Do I just call logging.basicConfig() a second time after daemonizing? What's the right way to capture stdout and stderr? I am fuzzy on the details of why all the files are closed. Ideally, my main code could just call daemon_start(pid_file) and logging would continue to work.

  • Export XML with only one MySQL request ?

    - by mere-teresa
    I want to export in XML format some data from 7 tables (MySQL database), and then I want to import in another database. And I have a update or insert rule for data. I already have a SQL query retrieving all data, with JOINs on my 7 tables. But...when I try to put data in XML format, I reach a limit. My PHP loop can catch each row, but I would like to benefit from hierachical structure of the XML, and all I have are rows with the same data repeated. It is better to query once and to construct the XML tree in PHP or to query each time I want access to a lower level ?
