  • ZEND - Creating custom routes without overwriting the default ones

    - by Pedro Cordeiro
    I'm trying to create something that looks like facebook's profile URL (http://facebook.com/username). So, at first I tried something like that: $router->addRoute( 'eventName', new Zend_Controller_Router_Route( '/:eventName', array( 'module' => 'default', 'controller' => 'event', 'action' => 'detail' ) ) ); I kept getting the following error: Fatal error: Uncaught exception 'Zend_Controller_Router_Exception' with message 'eventName is not specified' in /var/desenvolvimento/padroes/zf/ZendFramework-1.12.0/library/Zend/Controller/Plugin/Broker.php on line 336 Not only I was unable to make that piece of code work, all my default routes were (obviously) overwritten. So I have, for example, stuff like "mydomain.com/admin", that was now returning the same error (as it fell in the same pattern as /:eventName). What I need to do is to create this custom route, without overwriting the default ones and actually working (dûh). I have already checked the online docs and a lot (A LOT) of stuff on google, but I didn't find anything related to the error I'm getting or how to not overwrite the default routes. I'd appreciate anything that could point me the right direction. Thanks.

  • How difficult is it to write our own Robots API, similar to G Wave Robots API ? Please read the deta

    - by user169650
    Consider the following entities : a) My own Wave-server b) My own Robots API c) Tomcat d) Google wave server/any other wave server Let us consider that a and d interact with one another via Google wave federation protocol. Now, I want to write my own Robots API in Java (similar to that of G Wave Robots API) using which I want to create Robots; which I want to host in entity c), which may in-turn connect to a) for listening to events and responding with operations. Let us consider that a) is already in place, i.e. implemented. Let us also consider that the Robot running on tomcat and entity a) are co-located, so that we do not need to use JSON-RPC for receiving events/sending operations; instead we can use Java interfaces. Now, my questions are : 1.How much of an effort is it to write my own Robots API to run on a tomcat container ? 2.What are the salient points to be taken care of ? Am I missing some important point here ? 3.How can I reuse some of the classes/packages/interfaces (e.g. com.google.wave.api.AbstractRobot, com.google.wave.api.event) with little/no changes at all ?

    - by Geetha
    Hi All, I am using the following files to create a slider. Problem:Needs double click to change the handler position first click: it move the handler but the following code is not working. a second later it return back to the previous position. second click on the handler in new position, before it moves back the following code is working. Needs: I want change the media player current position with the handler current position value by dragging the handler or single click on the new position of the slider. Ex: initial position of the handler: l-------------------------------- document.mediaPlayer.currentPosition = 0 After dragging it some other position ----------------------l---------- document.mediaPlayer.currentPosition = 125 Code: var endTime = document.mediaPlayer.SelectionEnd; $("#slider-constraints").slider({ animate: true, max: endTime, range: $R(0, endTime), value: 1, enforceConstraints: false, start:function(event,index){document.mediaPlayer.currentPosition=index.value; $('#slider-constraints').slider("constraints", [0, index.value]); $('#slider-constraints').slider("value", index.value);} }); window.setInterval(function() { $('#slider-constraints').slider("value", document.mediaPlayer.currentPosition); }, 4000);

  • Why do touches only get detected ABOVE my CCBitmapFontAtlas and not ON it? (cocos2d)

    - by RexOnRoids
    I am detecting touches for CCBitmapFontAtlas (just text labels) as shown in the code below. But it seems that touches are only detected slightly ABOVE the CCBitmapFontAtlases? Did something get screwed when converting between coordinate systems? (*Note objects label1, label2, etc are CCBitmapFontAtlas) - (void)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { for( UITouch *touch in touches ) { CGPoint location = [touch locationInView:[touch view]]; location = [[CCDirector sharedDirector] convertToGL:location]; self.myGraphManager.isSliding = NO; CGRect rectLabel1 = CGRectMake(label1.position.x, label1.position.y, label1.contentSize.width, label1.contentSize.height); CGRect rectLabel2 = CGRectMake(label2.position.x, label2.position.y, label2.contentSize.width, label2.contentSize.height); CGRect rectLabel3 = CGRectMake(label3.position.x, label3.position.y, label3.contentSize.width, label3.contentSize.height); CGRect rectLabel4 = CGRectMake(label4.position.x, label4.position.y, label4.contentSize.width, label4.contentSize.height); CGRect rectLabel5 = CGRectMake(label5.position.x, label5.position.y, label5.contentSize.width, label5.contentSize.height); CGRect rectLabel6 = CGRectMake(label6.position.x, label6.position.y, label6.contentSize.width, label6.contentSize.height); if(CGRectContainsPoint(rectLabel1, location)){ NSLog(@"Label 1 Touched"); }else if(CGRectContainsPoint(rectLabel2, location)){ NSLog(@"Label 2 Touched"); }else if(CGRectContainsPoint(rectLabel3, location)){ NSLog(@"Label 3 Touched"); }else if(CGRectContainsPoint(rectLabel4, location)){ NSLog(@"Label 4 Touched"); }else if(CGRectContainsPoint(rectLabel5, location)){ NSLog(@"Label 5 Touched"); }else if(CGRectContainsPoint(rectLabel6, location)){ NSLog(@"Label 6 Touched"); } } }

  • Implementations details of drag and drop of file path in cocoa.

    - by foo
    Hi, I'm trying to get a part of my window to react to drag and drop. In this case to copy the file path to the file being dropped on the view. I have looked over some documentation but I still have some problems to see exactly where I should implement my methods for drag and drop. I have seen some examples but almost all of them assumes that I want to drop an image on the view. I'm pretty new to cocoa and Xcode so, I have some problems with seeing the exact relation between interface builder and the generated code. I have created a subclass to NSView, called drop zone like this: #import <Cocoa/Cocoa.h> @interface dropZone : NSView { } @end I then use an NSRect to color it grey like this: #import "dropZone.h" @implementation dropZone - (void)drawRect:(NSRect)rect { NSRect bounds = [self bounds]; [[NSColor grayColor] set]; [NSBezierPath fillRect:bounds]; } @end I then drag this class to my window in interface builder. But I will need to implement the registerForDraggingTypes method, but where? I have also seen a convenience method in the Apple docs for file paths like this: dragFile:fromRect:slideBack:event: that might work.

  • facebook comments ajax

    - by Shunsho
    I have a function that load a jquery ui accordion (differents accordions based on different id) When I click on the tab titled "Facebook Comments" I do: $("#myaccordion").bind('accordionchange', function(event, ui) { id = $("#myaccordion").data('id'); switch (ui.newHeader.text()) { case "Facebook Comments": displayFb(id); break; } }); The "displayFB" function is: function displayFb(id){ $.get('/fbcomments/' + id, function(data) { $("#facecomm").append(data); }); } Where www.myweb.com/fbcomments/id is: <div id="fb-root"></div> <script>(function(d, s, id) { var js, fjs = d.getElementsByTagName(s)[0]; if (d.getElementById(id)) return; js = d.createElement(s); js.id = id; js.src = "//connect.facebook.net/es_ES/all.js#xfbml=1"; fjs.parentNode.insertBefore(js, fjs); }(document, 'script', 'facebook-jssdk'));</script> <div class="fb-comments" data-href="<?php echo '/fbcomments/'.$id ?>" data-num-posts="10" data-width="220"></div> When I load the homepage, then choose an accordion, then open a Facebook Comments, it works perfect. If I reload the page and choose another accordion, work perfect again. The problem is when I choose another accordion or the same again without reload the whole page. The accordions loads very well, all the data on them (some tabs of images, text, videos, etc), but the facebook comments don't appear. I tried: loading the #fb-root and facebook comment <script> on the main layout....doesn't work. adding FB.XFBML.parse(); into displayFB function....doesn't work adding FB.XFBML.parse(); into a $(document).ready(function(){} ...doesn't work. Thank you for reading and try to help!!

  • Set bounds for markers generated by jQuery table loop?

    - by abemonkey
    I have some jQuery code that goes through a table of location results and puts corresponding pins on a map. I am having trouble figuring out how to set the bounds so that when it goes through the loop and generates the markers on the map that it zooms and pans to fit the markers in the view. I've tried implementing code from some similar questions on this site but nothing seems to be working. Please let me know what code I should be using and where the heck I should put it in my script: $(function() { var latlng = new google.maps.LatLng(44, 44); var settings = { zoom: 15, center: latlng, disableDefaultUI: false, mapTypeId: google.maps.MapTypeId.ROADMAP }; var map = new google.maps.Map(document.getElementById("map_canvas"), settings); $('tr').each(function(i) { var the_marker = new google.maps.Marker({ title: $(this).find('.views-field-title').text(), map: map, clickable: true, position: new google.maps.LatLng( parseFloat($(this).find('.views-field-latitude').text()), parseFloat($(this).find('.views-field-longitude').text()) ) }); var infowindow = new google.maps.InfoWindow({ content: $(this).find('.views-field-title').text() + $(this).find('.adr').text() }); new google.maps.event.addListener(the_marker, 'click', function() { infowindow.open(map, the_marker); }); }); }); `

  • when to use Hibernate vs. Simple ResultSets for small application

    - by luke
    I just started working on upgrading a small component in a distributed java application. The main application is a rather complicated applet/servlet combo running on JBoss and it extensively uses Hibernate for its DataAccess. The component i am working on however is very a very straightforward data importing service. Basically the workflow is Listen for a network event Parse the data packet, extract a set of identifiers Map the identifier set to a primary key in our database Parse the rest of the packet and insert items in a related table using the foreign key found in step 3 Repeat in the previous version of this component it used a hibernate based DAL, that is no longer usable for a variety of reasons (in particular it is EOL), so I am in charge of replacing the Data Access layer for this component. So on the one hand I think i should use Hibernate because that's what the rest of the application does, but on the other i think i should just use regular java.sql.* classes because my requirements are really straightforward and aren't expected to change any time soon. So my question is (and i understand it is subjective) at what point do you think that the added complexity of using an ORM tool (in terms of configuration, dependencies...) is worth it? UPDATE due to the way the DataAccesLayer for the main application was written (weird dependencies) i cannot easily use it, i would have to implement it myself.

  • Any web services with APIs for outsourcing webapp transactional email? [closed]

    - by Tauren
    My webapp needs to send customized messages to members and I'm wondering if there is an inexpensive and easy to use web service that would meet my needs. The types of mail I will be sending include: New account activation email (sent ASAP) Daily status report of user's account (sent anytime) Event reminders (sent at specific time) Specifically, I would like the following features: RESTful API to add an email message into the send queue A way to add a priority to each message (account signup activations should be sent immediately, while a daily status report could be sent anytime each day) They manage the sending of mail and the processing of bounces Possibly, they manage opt-out/opt-in features They offer features such as DKIM, VERP, etc. If their service determines an address is undeliverable (via VERP or other means, a user unsubscribes, etc), they make a RESTful call to my web service to notify me Nice if they had some reporting features, WebBugs, link tracking, etc. What I am NOT looking for is an email marketing service that caters only to sending out copies of the same mail to masses of recipients. I need to send out unique and custom messages to individuals. I had a chat with MailChimp about using their services for sending these types of messages and they said their service does not support customized emails per recipient. Edit: I just discovered a service called JangoSMTP that appears to meet many of my requirements. It provides an API for sending mail, supports DKIM, bounce management, and even feedback loops. Unfortunately, their idea of inexpensive doesn't mesh with mine, as it would cost $180/mo to send a single daily message to my 1000 users.

  • Where do I control the behavior of the "X" close button in the upper right of a winform?

    - by John at CashCommons
    I'm venturing into making my VB.NET application a little better to use by making some of the forms modeless. I think I've figured out how to use dlg.Show() and dlg.Hide() instead of calling dlg.ShowDialog(). I have an instance of my modeless dialog in my main application form: Public theModelessDialog As New dlgModeless To fire up the modeless dialog I call theModelessDialog.Show() and within the OK and Cancel button handlers in dlgModeless I have Private Sub OK_Button_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OK_Button.Click Me.DialogResult = System.Windows.Forms.DialogResult.OK Me.Hide() End Sub Private Sub Cancel_Button_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Cancel_Button.Click Me.DialogResult = System.Windows.Forms.DialogResult.Cancel Me.Hide() End Sub and that seems to work fine. The "X" button in the upper right is getting me, though. When I close the form with that button, then try to reopen the form, I get ObjectDisposedException was unhandled. Cannot access a disposed object. I feel like I'm most of the way there but I can't figure out how to do either of the following: Hide that "X" button Catch the event so I don't dispose of the object (just treat it like I hit Cancel) Any ideas? The class of this dialog is System.Windows.Forms.Form. Thanks as always!

  • ASP.NET DropDownList control doesn't postback correctly inside of UserControl

    - by RichardAZ
    I have a situation where a DropDownList control is not posting back correctly. The AutoPost property is set to true, so the postback does happen, but the SelectedValue is not set to the correct value. In addition, the onSelectedIndexChanged event doesn't fire. The exact same code works perfect fine on an ASPX page, but does not work in a ASCX control. I have tried all the obvious things, I hope, trying to figure this one out, but no luck so far. I have even investigated what comes back in Request.Form["__EVENTTARGET"] and __EVENTARGUMENT. __EVENTTARGET does point to the drop down list, but the argument is empty. Can the folks of StackOverflow help lead me in the right direction to debug this issue. Of course, it is further complicated by master pages and the usual overcomplication of ASP.NET. Here is the code: <div> <asp:DropDownList ID="testDrop" runat="server" AutoPostBack="true" EnableViewState="true" onselectedindexchanged="testDrop_SelectedIndexChanged"> <asp:ListItem Value="1" Text="1">1</asp:ListItem> <asp:ListItem Value="2" Text="2">2</asp:ListItem> </asp:DropDownList> </div> And here is the generated html: <select id="ctl00_MainContent_rptAccordion_ctl00_statControl_testDrop" onchange="javascript:setTimeout('__doPostBack(\'ctl00$MainContent$rptAccordion$ctl00$statControl$testDrop\',\'\')', 0)" name="ctl00$MainContent$rptAccordion$ctl00$statControl$testDrop"> <option value="1" selected="selected">1</option> <option value="2">2</option> THANKS!

  • Setting initial state of a JSF component to invalid

    - by user359391
    Hi there I have a small JSF application where the user is required to enter some data about themselves. For each component on the page that has required="true" I want to show an icon depending if there is data in the field or not. My problem is that when the page is initially shown all fields are valid, even if they do not have any data in them. So my question is how I can set a component to be invalid based on if there is data in the field or not? After a submit of the page (or after the component loses focus) the icon is shown properly, it is only on the initial page load I have a problem. (i.e there is no post data) Here is my xhtml for a component that needs to be validated: <s:decorate id="employeeIdDecoration" template="/general/util/errorStyle.xhtml"> <ui:define name="label">#{messages['userdetails.employeeId']}</ui:define> <h:inputText value="#{authenticator.user.employeeId}" required="true"> <a4j:support event="onblur" reRender="employeeIdDecoration" bypassUpdates="true"/> </h:inputText> the template: <s:label styleClass="#{invalid?'error':''}"> <ui:insert name="label"/> <s:span styleClass="required" rendered="#{required}">*</s:span> </s:label> <span class="#{invalid?'error':''}"> <s:validateAll> <ui:insert/> </s:validateAll> <h:graphicImage value="/resources/redx.png" rendered="#{invalid}" height="16" width="16" style="vertical-align:middle;"/> <h:graphicImage value="/resources/Checkmark.png" rendered="#{!invalid}" height="16" width="16" style="vertical-align:middle;"/> </span> Any help will be appreciated.

  • close other infowindows nicely.

    - by raklos
    Im currently doing this to create markers for my google map. function createMarker(posn, title, html) { var marker = new google.maps.Marker({ position: posn, title: title, draggable: false }); marker['infowindow'] = new google.maps.InfoWindow({ content: html }); infoWindows.push(marker['infowindow']); google.maps.event.addListener(marker, "click", function () { for (i = 0; i < infoWindows.length; i++) { infoWindows[i].close(); } this['infowindow'].open(map, this); }); return marker; } im not happy with the for loop, for closing the markers, i know something similar to this can be done by using one refernce: if (infowindow) infowindow.close(); the reason I am using code like above is because i am doing something like markers[myPoint]['infowindow'].open(map, markers[myPoint]); else where, (myPoint is a number). how can i avoid this for loop to close open infowindows and do it the nice way?

  • Updating a C# 2.0 events example to be idiomatic with C# 3.5?

    - by Damien Wildfire
    I have a short events example from .NET 2.0 that I've been using as a reference point for a while. We're now upgrading to 3.5, though, and I'm not clear on the most idiomatic way to do things. How would this simple events example get updated to reflect idioms that are now available in .NET 3.5? // Args class. public class TickArgs : EventArgs { private DateTime TimeNow; public DateTime Time { set { TimeNow = value; } get { return this.TimeNow; } } } // Producer class that generates events. public class Metronome { public event TickHandler Tick; public delegate void TickHandler(Metronome m, TickArgs e); public void Start() { while (true) { System.Threading.Thread.Sleep(3000); if (Tick != null) { TickArgs t = new TickArgs(); t.Time = DateTime.Now; Tick(this, t); } } } } // Consumer class that listens for events. public class Listener { public void Subscribe(Metronome m) { m.Tick += new Metronome.TickHandler(HeardIt); } private void HeardIt(Metronome m, TickArgs e) { System.Console.WriteLine("HEARD IT AT {0}",e.Time); } } // Example. public class Test { static void Main() { Metronome m = new Metronome(); Listener l = new Listener(); l.Subscribe(m); m.Start(); } }

  • S3 browser upload via POST: unable to handle errors gracefully

    - by samf
    I am writing an app where I want the customer to be able to upload to Amazon S3 straight from the browser. I can make this work just fine. But when errors occur, I want to handle them more gracefully than splattering an XML document on the customer's screen. I have a scheme that I think would work, but it's failing. Here's what I'm trying: Create a form to do the upload, and store the form on S3 itself, in the same domain as the "action" attribute of the form. Redirect the customer to this form. Now their browser is sitting on https://<bucket>.s3.amazonaws.com/something. The page contains a hidden iframe. The form sets its target to the iframe. The load event handler looks at the contents of the iframe, and acts upon it. So, something like this: <iframe id="foo" name="foo" style="display: none" /> <form target="foo" action="https://<bucket>.s3.amazonaws.com/"> <input type="hidden" name="..." value="..." /> <input type="file" name="file" /> </form> with this javascript (using jquery): function handler() { var message = $("#foo").contents().find('message').text(); alert(message); } $("#foo").load(handler); Using firebug, I can see that the iframe contains an XML document, that contains a "message" node. However, the .find('message') always fails to find anything within the XML document. Notice that the action of the form has the same domain, port, and scheme as the document itself. So, I don't think that I should be running afoul of the same-origin policy. Right? But it fails every time. This is using Firefox and Google Chrome browsers. Thanks for any advice!

  • Accelerometer stops delivering samples when the screen is off on Droid/Nexus One even with a WakeLoc

    - by William
    I have some code that extends a service and records onSensorChanged(SensorEvent event) accelerometer sensor readings on Android. I would like to be able to record these sensor readings even when the device is off (I'm careful with battery life and it's made obvious when it's running). While the screen is on the logging works fine on a 2.0.1 Motorola Droid and a 2.1 Nexus One. However, when the phone goes to sleep (by pushing the power button) the screen turns off and the onSensorChanged events stop being delivered (verified by using a Log.e message every N times onSensorChanged gets called). The service acquires a wakeLock to ensure that it keeps running in the background; but, it doesn't seem to have any effect. I've tried all the various PowerManager. wake locks but none of them seem to matter. _WakeLock = _PowerManager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "My Tag"); _WakeLock.acquire(); There have been conflicting reports about whether or not you can actually get data from the sensors while the screen is off... anyone have any experience with this on a more modern version of Android (Eclair) and hardware? This seems to indicate that it was working in Cupcake: http://groups.google.com/group/android-developers/msg/a616773b12c2d9e5 Thanks! PS: The exact same code works as intended in 1.5 on a G1. The logging continues when the screen turns off, when the application is in the background, etc.

  • Error with threads during automatic testing on TeamCity 5

    - by yeyeyerman
    Hello, I'm having some problems executing the tests of the application I'm developing. All the tests execute normally with ReSharper and in NCover. However, the execution of one of these tests in TeamCity is generating an error. This test initializes two objects, the object under test and a simulator of a real object. Both objects will communicate throug a serial link in a representation of the real scenario. ObjectSimulator r_simulator = new ObjectSimulator(...); ObjectDriver r_driver = new ObjectDriver(...); Assert.IsTrue(r_driver.Connect() == ErrorCode.Success); The simulator just do the following in the constructor public class ObjectSimulator { ... public ObjectSimulator() { // serial port configuration m_port = new SerialPort(); m_port.DataReceived += DataReceivedEvent; } ... } The main object has two threads. The main thread of the application and a timer to refresh a watchdog timer in the real object. public ErrorCode Connect() { ... StartSynchroTimer(); Thread.Sleep(4); // to check if the timer is working properly ... } The problem is comming from the Thread.Sleep() call, as when I remove it everything works. It seems like the ObjectSimulator also sleeps and doesn't receive the DataReceived event. How can I resolve this issue?

  • Flex: Scale an Image so that its width matches contentWidth?

    - by Tong Wang
    I have a dynamic layout, where an image is loaded into an HBox: <mx:HBox ...> <mx:Image height="100%" .../> </mx:HBox> only the image's height is set on the image, so that it can take all the vertical space available, while its width is left undefined and I expect the width to scale accordingly with its height. It turns out that the image's height is equal to its contentHeight, i.e. height scales properly; however, the image's width is still the same as measuredWidth (the image's original width), and is not scaled accordingly. For example, if the image's original size is 800x600 and if the HBox is 300 in height, then image height will scale down to 300, however its width doesn't scale down to 400, instead it stays at 800. I tried to add an event listener to explicitly set the image width: <mx:Image id="img" height="100%" updateComplete="img.width=img.contentWidth;" .../> It works only the first time the image is loaded, after that, if I use Image.load() to dynamically load different images, it stops working - the image width is set to 0. Any help/advice will be highly appreciated.

  • What is the fastest (to access) struct-like object in Python?

    - by DNS
    I'm optimizing some code whose main bottleneck is running through and accessing a very large list of struct-like objects. Currently I'm using namedtuples, for readability. But some quick benchmarking using 'timeit' shows that this is really the wrong way to go where performance is a factor: Named tuple with a, b, c: >>> timeit("z = a.c", "from __main__ import a") 0.38655471766332994 Class using __slots__, with a, b, c: >>> timeit("z = b.c", "from __main__ import b") 0.14527461047146062 Dictionary with keys a, b, c: >>> timeit("z = c['c']", "from __main__ import c") 0.11588272541098377 Tuple with three values, using a constant key: >>> timeit("z = d[2]", "from __main__ import d") 0.11106188992948773 List with three values, using a constant key: >>> timeit("z = e[2]", "from __main__ import e") 0.086038238242508669 Tuple with three values, using a local key: >>> timeit("z = d[key]", "from __main__ import d, key") 0.11187358437882722 List with three values, using a local key: >>> timeit("z = e[key]", "from __main__ import e, key") 0.088604143037173344 First of all, is there anything about these little timeit tests that would render them invalid? I ran each several times, to make sure no random system event had thrown them off, and the results were almost identical. It would appear that dictionaries offer the best balance between performance and readability, with classes coming in second. This is unfortunate, since, for my purposes, I also need the object to be sequence-like; hence my choice of namedtuple. Lists are substantially faster, but constant keys are unmaintainable; I'd have to create a bunch of index-constants, i.e. KEY_1 = 1, KEY_2 = 2, etc. which is also not ideal. Am I stuck with these choices, or is there an alternative that I've missed?

  • Whether to put method code in a VB.Net data storage class, or put it in a separate class?

    - by Alan K
    TLDR summary: (a) Should I include (lengthy) method code in classes which may spawn multiple objects at runtime, (b) does doing so cause memory usage bloat, (c) if so should I "outsource" the code to a class that is loaded only once and have the class methods call that, or alternatively (d) does the code get loaded only once with the object definition anyway and I'm worrying about nothing? ........ I don't know whether there's a good answer to this but if there is I haven't found it yet by searching in the usual places. In my VB.Net (2010 if it matters) WinForms project I have about a dozen or so class objects in an object model. Some of these are pretty simple and do little more than act as data storage repositories. The ones further up the object model, however, have an increasing number of methods. There can be a significant number of higher level objects in use though the exact number will be runtime dependent so I can't be more precise than that. As I was writing the method code for one of the top level ones I noticed that it was starting to get quite lengthy. Memory optimisation is something of a lost art given how much memory the average PC has these days but I don't want to make my application a resource hog. So my questions for anyone who knows .Net way better than I do (of which there will be many) are: Is the code loaded into memory with each instance of the class that's created? Alternatively is it loaded only once with the definition of the class, and all derived objects just refer to that definition? (I'm not really sure how that could be possible given that, for example, event handlers can be assigned dynamically, but no harm asking.) If the answer to the first one is yes, would it be more efficient to write the code in a "utility" object which is loaded only once and called from the real class' methods? Any thoughts appreciated.

  • Custom API requirement

    - by Jonathan.Peppers
    We are currently working on an API for an existing system. It basically wraps some web-requests as an easy-to-use library that 3rd party companies should be able to use with our product. As part of the API, there is an event mechanism where the server can call back to the client via a constantly-running socket connection. To minimize load on the server, we want to only have one connection per computer. Currently there is a socket open per process, and that could eventually cause load problems if you had multiple applications using the API. So my question is: if we want to deploy our API as a single standalone assembly, what is the best way to fix our problem? A couple options we thought of: Write an out of process COM object (don't know if that works in .Net) Include a second exe file that would be required for events, it would have to single-instance itself, and open a named pipe or something to communicate through multiple processes Extract this exe file from an embedded resource and execute it None of those really seem ideal. Any better ideas?

  • How to close and open access to SQL Server 2008 in Windows application?

    - by hgulyan
    Hi, I have a MS Access 97 application (but the question is general) working directly with SQL Server 2008 (without application server or anything). Numbers of users can be up to 1000. Windows Authentication is used. The question is: How to handle modes, so some users will be allowed to work in read-only mode some users won't have access to db for some time My versions: Using a table with a mode id for every group of users, that will work the same way. On Form Load application will query that table for mode id. Using trigger on the tables, that must work according to that mode. The trigger will query mode value and doesn't work if access is closed or it's in read-only mode I know these are not the best solutions, that's why I'm asking for your advice. There's one more point. If the mode is changed to "access-is-closed" for a group of users, that group must not be able to query to DB starting that moment. With first solution I wrote it won't work, because user can be in application at that moment and no form load event will work. How can I do this? Is there any optimal solution? Thank you. Any help would be appreciated.
