  • Limiting the number of threads executing a method at a single time.

    - by Steve_
    We have a situation where we want to limit the number of paralell requests our application can make to its application server. We have potentially 100+ background threads running that will want to at some point make a call to the application server but only want 5 threads to be able to call SendMessage() (or whatever the method will be) at any one time. What is the best way of achieving this? I have considered using some sort of gatekeeper object that blocks threads coming into the method until the number of threads executing in it has dropped below the threshold. Would this be a reasonable solution or am I overlooking the fact that this might be dirty/dangerous? We are developing in C#.NET 3.5. Thanks, Steve

  • Get notified/receive explicit intents when an activity starts

    - by qtips
    Hi, I am developing an application than gets notified when an activity chosen by a user is started. For this to work, the best approach would be to register a broadcastreceiver for ACTION_MAIN explicit intents, which as far as I know doesn't work (because these intents have specific targets). Another, probably less efficient approach, is to use the system ActivityManager and poll on the getRunningTask() which returns a list of all running tasks at the moment. The polling can be done by a background service. By monitoring the changes in this list, I can see whether an activity is running or not, so that my application can get notified. The downside is ofcourse the polling. I have not tried this yet, but I think that this last approach will probably work. Does anyone know of a better approach(es) or suggestions which are less intensive?

    - by Sergio
    If the doctype declaration is <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 TRANSITIONAL//EN"> what is the best way for horizontal alignment of the DIV's like these: <div id="outer"><div id="inner">Some text</div></div> The CSS is: #outer{ border-top:1px dotted #999; background-color: #F4F4F4; width:100%;} #inner{ width:500px;border:1px solid #F00; margin:auto;} The thing that I want to do is the inner DIV align at center (horizontally) inside the outer DIV.

  • How to detect tap on uiview with lots of controls?

    - by kodcu
    My problem is about tap detection. I have a uiviewcontroller and there are some controls on uiview (labels, buttons, tableview, imageview, etc..) When I tap the uibutton I display a small uiview (200x150), if the user taps the uibuttons in smallview I hide the smallview. But I can't hide the uiview if the user taps the background. I tried this code.. -(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ //NSLog(@"Touches began."); [self hideShareView]; } It doesn't work if I tap the another button in the uiviewcontrols view. I just want my uiviewcontrol's uiview to react first. I think its about firstResponder but I dont know how to set it first. edit: i want it to work like a uiPopover in ipad.

  • How to force a line break in a loooooong word in a DIV?

    - by George Edison
    Okay, this is really confusing me. I have some content inside of a div like so: <div style="background-color: green; width: 200px; height: 300px;"> Thisisatest.Thisisatest.Thisisatest.Thisisatest.Thisisatest.Thisisatest. </div> However, the content overflows the DIV (as expected) because the 'word' is too long. How can I force the browser to 'break' the word where necessary to fit all of the content inside?

  • How can you set a time limit for a PowerShell script to run for?

    - by calrain
    I want to set a time limit on a PowerShell (v2) script so it forcibly exits after that time limit has expired. I see in PHP they have commands like set_time_limit and max_execution_time where you can limit how long the script and even a function can execute for. With my script, a do/while loop that is looking at the time isn't appropriate as I am calling an external code library that can just hang for a long time. I want to limit a block of code and only allow it to run for x seconds, after which I will terminate that code block and return a response to the user that the script timed out. I have looked at background jobs but they operate in a different thread so won't have kill rights over the parent thread. Has anyone dealt with this or have a solution? Thanks!

  • turning text into image - PHP/GD - save image

    - by Phil Jackson
    Hi, I'm using this script to simply create an image from text. What I would like to know is how to save the image instead of printing straight to browser; // an email address in a string $string = $post[$key]; // some variables to set $font = 4; $width = ImageFontWidth($font) * strlen($string); $height = ImageFontHeight($font); // lets begin by creating an image $im = @imagecreatetruecolor ($width,$height); //white background $background_color = imagecolorallocate ($im, 255, 255, 255); //black text $text_color = imagecolorallocate ($im, 0, 0, 0); // put it all together $image = imagestring ($im, $font, 0, 0, $string, $text_color); I know its probably just one line of code at the end but im not sure which GD function to use. Any help would be much appreciated, Regards, Phil.

  • NSAutoreleasePool carrying across methods?

    - by Tim
    I'm building an iPhone application where I detach some threads to do long-running work in the background so as not to hang the UI. I understand that threads need NSAutoreleasePool instances for memory management. What I'm not sure about is if the threaded method calls another method - does that method also need an NSAutoreleasePool? Example code: - (void)primaryMethod { [self performSelectorInBackground:@selector(threadedMethod) withObject:nil]; } - (void)threadedMethod { NSAutoreleasePool *aPool = [[NSAutoreleasePool alloc] init]; // Some code here [self anotherMethod]; // Maybe more code here [aPool drain]; } - (void)anotherMethod { // More code here } The reason I ask is I'm receiving errors that objects are being autoreleased with no pool in place, and are "just leaking." I've seen other questions where people didn't have autorelease pools in place at all, and I understand why an autorelease pool is needed. I'm specifically interested in finding out whether an autorelease pool created in (in this example) threadedMethod applies to objects created in anotherMethod.

  • Caurina Tweener and Alpha

    - by Jk_
    Hi guys, Usually I work with TweenLite but I had to modify the code of someone else who worked with Caurina Tweener. I have a basic problem with it! On my scene, I have a simple movie clip filled with black. Into this movieclip a bitmap file (jpg). When I make a tween on the alpha of my mc, it seems that there is a delay (in the alpha) between this the black background and the image. Tweener.addTween(thisMc, { _autoAlpha:0, time:1 } ); I'm sure there is an easy way to avoid this problem but I can't find it out! Cheers, Jk_

  • How to center drawableTop and text vertically on the Button in Android?

    - by Gaks
    I have the Button defined as follows: <Button android:drawableTop="@drawable/ico" android:gravity="center" android:id="@+id/StartButton2x2" android:text="@string/Widget2x2StartBtnLabel" android:layout_width="0dip" android:layout_height="fill_parent" android:layout_weight="1" android:background="@drawable/widgetbtn_bg" /> The problem is that 'drawableTop' image is aligned to the top border of the Button view. I would like to center it (together with text label) vertically on the button. 'android:gravity' seems to work only on text label. It does not affect 'drawableTop' positioning. I was able to center it vertically using 'android:paddingTop' - but that does not seem to be a good idea. I guess it would not work properly on different screen resolution/size.

  • Javascript global variable not working properly?

    - by Fabian
    My jQuery code: $(document).ready(function() { chrome.extension.sendRequest({get: "height"}, function(response) { height = response.value; }); $("#id").css("height", height+"px"); }); You don't have to be concerned about the chrome.extension.sendRequest(), basically it communicates with a background page to fetch the value for "height" from localStorage and stores the value in global variable height. The problem lies in $("#id") not being assigned the height value. However if I were to modify it such that it is now: $(document).click(function() { $("#id").css("height", height+"px"); }); it works. Any idea why?

  • Android views' borders issue on some devices

    - by htafoya
    Hi there, Some users have been reporting border alignment issues on some android components such as the alert popup or the editTexts. This is happening on the Samsung Galaxy Apollo (200x400) and the HTC Pro Touch (480x640) devices. I cannot replicate that because i don't own those devices and in the Samsung Galaxy S and emulator everything looks just right. I think that the problem is the dpi or resolution of the device (because the edittext background is a single .9.png so image should look ok); however I am not sure if the supports-screens tag is the solution. Also, application was developed using Api 3 (v1.5) and supports-screens was not yet supported, nor the screen-size resource qualifier. The style used for the alerts and editText is the phone default. Could the problem be something related with the theme applied to the phone by the user? Thanks in advance!, I show some images given to me showing the problem: //EDIT: I can't post images because i am new; i will put a link: borders issue link img

  • Webservice and ORM Framework?

    - by Sebastian
    Does anybody know a good web framework that includes an ORM mapper and allows straight forward implementation of web services? I'm looking for a framework written in PHP or C++. I'm looking for the following features (not all of them required, some will do nicely) data definition in one place used by database and web service WSDL generation XML output/JSON output boilerplate code generation So what I would like is a framework that let's me specify the objects, the web service functions on those objects and then generate everything that is required leaving me to fill the business logic (connecting the database to the web service). Anything like that out there? Background information for why I need this: I'm looking into creating a web project: the client is a rich web application that fetches all its data using AJAX. It will be completely custom made using only a low level javascript library. The server back end is supposed to serve static content and javascript (basically the rich web application) and to provide a RESTful web service API (which I would like to implement using aforementioned framework).

  • overflow-x AND Middle Mouse Button Moving

    - by Rad The Mad
    My Page is 980px in Width, but I have a few design elements (which belong with the background). I positioned them with position: absolute;. This creates a horizontal scrollbar for those who have a =< 1024 resolution. I disabled that scrollbar with overflow-x:hidden on (and for IE7 and etc). However, when I hold my middle mouse button,(i think this applies to laptop touchpads as well) it let's me move around to the right, is it possible to fix this with anything? (javascript, css)? Tested this issues in Chrome, IE, Firefox.

  • Force redraw before long running operations

    - by Joshua
    When you have a button, and do something like: Private Function Button_OnClick Button.Enabled = False [LONG OPERATION] End Function Then the button will not be grayed, because the long operation prevents the UI thread from repainting the control. I know the right design is to start a background thread / dispatcher, but sometimes that's too much hassle for a simple operation. So how do I force the button to redraw in disabled state? I tried .UpdateLayout() on the Button, but it didn't have any effects. I also tried System.Windows.Forms.DoEvents() which normally works when using WinForms, but it also had no effect.

  • jQuery Validation plugin: prompt for override

    - by Sam Carleton
    I have a jQuery form that has validation of a sort. It is a data entry screen with two 'recommend ranges', one is 36-84, the other 50-300. The business rules call for the values to be either blank or greater than zero, but to prompt for confirmation if the values are outside of the range listed above. I have seen some other threads that talk about setting the class="cancel" on the submit button. From what I can tell, this will simply disable the validation. I need to prompt for a "do you want to continue, yes or no?" and if no stop the submit, if yes, continue. Below is an example from the book Pro jQuery. By default the top row needs to be between 10 and 20 to submit. How would you change it so that it prompts you and if you say Yes it submits, no prevents the submit: <!DOCTYPE html> <html> <head> <title>Example</title> <script src="jquery-1.7.js" type="text/javascript"></script> <script src="jquery.tmpl.js" type="text/javascript"></script> <script src="jquery.validate.js" type="text/javascript"></script> <style type="text/css"> h1 { min-width: 70px; border: thick double black; margin-left: auto; margin-right: auto; text-align: center; font-size: x-large; padding: .5em; color: darkgreen; background-image: url("border.png"); background-size: contain; margin-top: 0; } .dtable {display: table;} .drow {display: table-row;} .dcell {display: table-cell; padding: 10px;} .dcell > * {vertical-align: middle} input {width: 2em; text-align: right; border: thin solid black; padding: 2px;} label {width: 5em; padding-left: .5em; display: inline-block;} #buttonDiv {text-align: center;} #oblock {display: block; margin-left: auto; margin-right: auto; min-width: 700px; } div.errorMsg {color: red} .invalidElem {border: medium solid red} </style> <script type="text/javascript"> $(document).ready(function() { var data = [ { name: "Astor", product: "astor", stocklevel: "10", price: "2.99"}, { name: "Daffodil", product: "daffodil", stocklevel: "12", price: "1.99"}, { name: "Rose", product: "rose", stocklevel: "2", price: "4.99"}, { name: "Peony", product: "peony", stocklevel: "0", price: "1.50"}, { name: "Primula", product: "primula", stocklevel: "1", price: "3.12"}, { name: "Snowdrop", product: "snowdrop", stocklevel: "15", price: "0.99"}, ]; var templResult = $('#flowerTmpl').tmpl(data); templResult.slice(0, 3).appendTo('#row1'); templResult.slice(3).appendTo("#row2"); $('form').validate({ highlight: function(element, errorClass) { $(element).add($(element).parent()).addClass("invalidElem"); }, unhighlight: function(element, errorClass) { $(element).add($(element).parent()).removeClass("invalidElem"); }, errorElement: "div", errorClass: "errorMsg" }); $.validator.addClassRules({ flowerValidation: { required: true, min: 0, max: 100, digits: true, } }) $('#row1 input').each(function(index, elem) { $(elem).rules("add", { min: 10, max: 20 }) }); $('input').addClass("flowerValidation").change(function(e) { $('form').validate().element($(e.target)); }); }); </script> <script id="flowerTmpl" type="text/x-jquery-tmpl"> <div class="dcell"> <img src="${product}.png"/> <label for="${product}">${name}: </label> <input name="${product}" value="0" required /> </div> </script> </head> <body> <h1>Jacqui's Flower Shop</h1> <form method="post" action="http://node.jacquisflowershop.com/order"> <div id="oblock"> <div class="dtable"> <div id="row1" class="drow"> </div> <div id="row2"class="drow"> </div> </div> </div> <div id="buttonDiv"><button type="submit">Place Order</button></div> </form> </body> </html>

  • Database Abstraction & Factory Methods

    - by pws5068
    I'm interested in learning more about design practices in PHP for Database Abstraction & Factory methods. For background, my site is a common-interest social networking community currently in beta mode. Currently, I've started moving my old code for object retrieval to factory methods. However, I do feel like I'm limiting myself by keeping a lot of SQL table names and structure separated in each function/method. Questions: Is there a reason to use PEAR (or similar) if I dont anticipate switching databases? Can PEAR interface with the MySqli prepared statements I currently use? Will it help me separate table names from each method? (If no, what other design patterns might I want to research?) Will it slow down my site once I have a significantly large member base?

  • Which PHP framework for a RoR developer?

    - by Horace Ho
    For one specific client I have to use PHP. This and this question were 2 years old. I'd like to know is there any update of opinion for year 2010? My background on web development is mainly rails. I can code in PHP (for example, write a module for Drupal) but never used any PHP framework for any project. I can see the following potential features to be needed in my project: authlogic-like user access control will_paginate-like paging for long listings paperclip-like simple file upload prawn-like PDF generation restful url and my personal favorite ruby/rails features: activerecord <% @list.each do |item| %> synstax instead of for ($i=1; $i<=$row_num; $i++) ... rake:db migrate script/console Thanks!

  • JFrame.setBackground() not working -- why?

    - by devoured elysium
    JFrame mainFrame = new JFrame(); mainFrame.setSize(100, 100); mainFrame.setBackground(Color.CYAN); mainFrame.setVisible(true); My intent is to create a window with a cyan background. What is wrong with this? My window doesn't get cyan, as I'd expect! Also, could anyone point out why I seem to have all the colors in duplicate (there's a Color.CYAN and a Color.cyan). Is there any difference at all between the two? Maybe the older one was a constant from before there were enums in Java and the second one is from the Enum? Thanks
