• jni4net - how to set the absolute path to jni4net.j-0.7.1.0.jar

  - by w1z

  Guys, help me... I use jni4net in my WCF service. in the ctor of the service I try to create BridgeSetup object. var bridgeSetup = new BridgeSetup(false); bridgeSetup.AddAllJarsClassPath("."); Bridge.CreateJVM(bridgeSetup); As I understand in this moment jni4ne tryes to generate jni4net.j-0.7.1.0.dll from jni4net.j-0.7.1.0.jar. It tryes to find jni4net.j-0.7.1.0.jar near the jni4net.n-0.7.1.0.dll and can't. So I get next error... c:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\fileprocessingservice\76f0fa69\5db44426\assembly\dl3\4fa263c6\f424b7fa_c8ccca01\jni4net.j-0.7.1.0.DLL Anybody know how to solve the problem? Thanks..

• Tutorial on Using OpenSSL with pthreads

  - by Sadeq Dousti

  OpenSSL documents state that it can safely be used in multi-threaded applications provided that at least two callback functions are set, locking_function and threadid_func.... I've written programs which use OpenSSL API. Moreover, I know how to use pthreads. However, the OpenSSL documents are written in the form of a manual, and I can't see a step-by-step guide on what I have to do when using OpenSSL in a multi-threaded app. Is there a tutorial on using OpenSSL with pthreads? (I searched the web, but no satisfactory result appeared.) PS: I'm working in Debian Lenny & Ubuntu Lucid/Maverick. PS2: OpenSSL includes a sample, but it's far too complicated to start with.

• Serializing data using IEnumerable<T> with WebGet

  - by Jim

  possible duplicate: Cannot serialize parameter of type ‘System.Linq.Enumerable… ’ when using WCF, LINQ, JSON Hi, If my method signiature looks like this, it works fine. [WebGet] MyClass[] WebMethod() If the signiature looks like this [WebGet] IEnumerable<T> WebMethod() I get the following error: Cannot serialize parameter of type 'X.Y.Z.T+<WebMethod>d__2c' (for operation 'WebMethod', contract 'IService') because it is not the exact type 'System.Collections.Generic.IEnumerable`1[X.Y.Z.T]' in the method signature and is not in the known types collection. In order to serialize the parameter, add the type to the known types collection for the operation using ServiceKnownTypeAttribute. I have tried adding. ServiceKnownType(typeof(IEnumerable)) Same error. Is this a bug in 2010 beta 2, or is this likely to be correct going forward? Thanks

• Trigger event after GDirections.loadFromWaypoints in Google Maps API

  - by Soldarnal

  I'm attempting to add some text to the directions results the Google Maps API returns to the specified div (directionsPanel). This code below would work fine, except that the jQuery line fires before loadFromWaypoints has finished modifying the DOM. If I run that line by manually triggering it after the directions content has finished loading, it executes as expected. directions = new GDirections(map, directionsPanel); directions.loadFromWaypoints(waypoints); $("td[@jscontent='address']").append(" some content"); How can I add some sort of listener (on perhaps either the loadFromWaypoints callback function or the directionsPanel div itself) to execute my jQuery line after the DOM has finished reloading?

• Why do users have to enter a 7-digit twitter PIN to grant my application access?

  - by Tony

  I am implementing some ruby on rails code tweet stuff for my users. I am creating the proper oauth link...something like http://twitter.com/oauth/authorize?oauth_token=y2RkuftYAEkbEuIF7zKMuzWN30O2XxM8U9j0egtzKv But after my test account grants access to twitter, it pulls up a page saying "You've successfully granted access to . Simply return to and enter the following PIN to complete the process. 1234567" I have no idea where the user should enter this PIN and why they have to do that. I don't think this should be a necessary step. Twitter should be redirecting the user to the callback URL I provided in the application settings. Does anyone know why this is happening? UPDATE I found this article that states I need to send my users to this URL (note "authenticate" instead of "authorize"): http://twitter.com/oauth/authenticate?oauth_token=y2RkuftYAEkbEuIF7zKMuzWN30O2XxM8U9j0egtzKv I made the change but Twitter redirects the user to the authorize path after he clicks "Allow" which then gives him the 7 digit PIN again!

• Delegate, BeginInvoke. EndInvoke - How to clean up multiple Async threat calls to the same delegate?

  - by Dan

  I've created a Delegate that I intend to call Async. Module Level Delegate Sub GetPartListDataFromServer(ByVal dvOriginal As DataView, ByVal ProgramID As Integer) Dim dlgGetPartList As GetPartListDataFromServer The following code I use in a method Dim dlgGetPartList As New GetPartListDataFromServer(AddressOf AsyncThreadMethod_GetPartListDataFromServer) dlgGetPartList.BeginInvoke(ucboPart.DataSource, ucboProgram.Value, AddressOf AsyncCallback_GetPartListDataFromServer, Nothing) The method runs and does what it needs to The Asyn callback is fired upon completion where I do an EndInvoke Sub AsyncCallback_GetPartListDataFromServer(ByVal ar As IAsyncResult) dlgGetPartList.EndInvoke(Nothing) End Sub It works as long as the method that starts the BeginInvoke on the delegate only ever runs while there is not a BeginInvoke/Thread operation already running. Problem is that the a new thread could be invoked while another thread on the delegate is still running and hasnt yet been EndInvoke'd. The program needs to be able to have the delegate run in more than one instance at a time if necessary and they all need to complete and have EndInvoke called. Once I start another BeginInvoke I lose the reference to the first BeginInvoke so I am unable to clean up the new thread with an EndInvoke. What is a clean solution and best practice to overcome this problem?

• ASP.NET MVC Response Filter + OutputCache Attribute

  - by Shane Andrade

  I'm not sure if this is an ASP.NET MVC specific thing or ASP.NET in general but here's what's happening. I have an action filter that removes whitespace by the use of a response filter: public class StripWhitespaceAttribute : ActionFilterAttribute { public StripWhitespaceAttribute () { } public override void OnResultExecuted(ResultExecutedContext filterContext) { base.OnResultExecuted(filterContext); filterContext.HttpContext.Response.Filter = new WhitespaceFilter(filterContext.HttpContext.Response.Filter); } } When used in conjunction with the OutputCache attribute, my calls to Response.WriteSubstitution for "donut hole caching" do not work. The first and second time the page loads the callback passed to WriteSubstitution get called, after that they are not called anymore until the output cache expires. I've noticed this with not just this particular filter but any filter used on Response.Filter... am I missing something? I also forgot to mention I've tried this without the use of an MVC action filter attribute by attaching to the PostReleaseRequestState event in the global.asax and setting the Response.Filter value there... but still no luck.

• EF4, MVC 3, Azure and Code First or Traditional

  - by RichardAlanA

  I am planning to build a web application using ASP MVC3 that runs on Azure with a SQL Azure back end. I would like to use the Microsoft stack and have no plans to ever change to another stack. I am looking into the use of WCF and WF but that would be in the future. I looked at the traditional and Code First approach to using Entity Framework but I can't see if there is any advantage in using one or the other approach. Sure they each have advantages but for me I don't care if my classes do inherit from EF classes. All I want is to find the most efficient solution. Can anyone out there give me some advice as to which approach might be the best. thanks very much Richard

• using AudioQueues with AudioFileReadBytes

  - by Santosh

  Hey Im trying to work with Audio queues to play a very big mp3 file (arround 23 hours long). when audio queue asks for buffers though callback, im using AudioFileReadBytes() API to read the bytes from audio file and feed the queue. startQueue fails with the error : prime failed any inputs????? Also I succeeded playing file using AudioFileReadPackets API instead of AudioFileReadBytes(). But the problem with API is that when I seek (fast forward) by a long interval, say 9 hours (for example fast forward from 32 mins playtime to 9:32 mins) then AudioFileReadPackets() takes a long time (almost 2 mins) to read from new location. any comments would be greatly appreciated.

• AJAX call in for loop won't return values to correct array positions

  - by Heilemann

  I need to get a range of pages using AJAX and put them into an array, where their given place in the array is equal to the i of a for loop (it's a caching-like function for blog pages, and the range of the for loop is entirely variable). I'm doing something akin to the following: var bongo = new Array(); for (i = 0; i < 10; i++) { jQuery.ajax({ type: "GET", url: http://localhost, data: queryString, success: function(request) { bongo[i] = request } }) } The problem is, that unless I add async: false to the .ajax options (which would make it... SJAX?), which causes the requests to basically pause the browser, going against what I'm trying to do, the i in the success callback will always end up being 11, whereas I of course want it to pour the returned data into each slot of the array from 0 to 10. I've tried replacing the line with this: bongo[i] = jQuery.ajax({ type: "GET", url: http://localhost, data: queryString }).responseText But that made no difference.

• How to marshal a COM-Parameter as VT_ARRAY of VT_RECORD

  - by Oliver Japes

  I've already done some extensive search, but I can't seem to find anything matching my problem. The task I'm currently working on is to create a WCF-Wrapper for some DCOM-Objects. This already works great for the most parts, but now I'm stuck with one invocation that expects a VT_ARRAY containing VT_RECORD-Objects. Marshalling as VT_ARRAY is not a problem, but how can I tell COM that the elements in this array are VT_RECORDs? This is the invocation as I current use it. InitTestCase(testCaseName, parameterFileName, testCase, cellInfos.ToArray()); The parameter I'm talking about is the last one. It's defined as List<CellInfo>, CellInfo itself is already attributed with Guid("7D422961-331E-47E2-BC71-7839E9E77D39") and ComVisible(true). It's not a struct but a class. This is the condition failing on the native side: if (VT_RECORD == varCellConfig.vt)... Because of old software using these interfaces, changing the native side is not an option Any idea?

• Re-Apply currency formatting to a UITextField on a change event

  - by Jim Aldes

  Howdy all, I'm working with a UITextField that holds a localized currency value. I've seen lots of posts on how to work with this, but my question is: how do I re-apply currency formatting to the UITextField after every key press? I know that I can set up and use a currency formatter with: NSNumberFormatter *currencyFormatter = [[NSNumberFormatter alloc] init]; [currencyFormatter setNumberStyle:NSNumberFormatterCurrencyStyle]; ... [currencyFormatter stringFromNumber:...]; but I don't know how to hook it up. For instance, if the value in the field reads "$12,345" and the user taps the "6" key, then the value should change to "$123,456". Which callback is the "correct" one to do this in (should I use textField:shouldChangeCharactersInRange:replacementString: or a custom target-action) and how do I use the NSNumberFormatter to parse and re-apply formatting to the UITextField's text property? Any help would be much appreciated! Thanks!

• Few Google Checkout Questions

  - by Richard Knop

  I am planning to integrate a Google Checkout payment system on a social networking website. The idea is that members can buy "tokens" for real money (which are sort of the website currency) and then they can buy access to some extra content on the website etc. What I want to do is create a Google Checkout button that takes a member to the checkout page where he pays with his credit or debit card. What I want is the Google Checkout to notify notify my server whether the purchase of tokens was successful (if the credit/debit card was charged) so I can update the local database. The website is coded in PHP/MySQL. I have downloaded the sample PHP code from here: code.google.com/p/google-checkout-php-sample-code/wiki/Documentation I know how to create a Google checkout button and I have also placed the responsehandlerdemo.php file on my server. This is the file the Google Checkout is supposed to send response to (of course I set the path to the file in Google merchant account). Now in the response handler file there is a switch block with several case statements. Which one means that the payment was successful and I can add tokens to the member account in the local database? switch ($root) { case "request-received": { break; } case "error": { break; } case "diagnosis": { break; } case "checkout-redirect": { break; } case "merchant-calculation-callback": { // Create the results and send it $merchant_calc = new GoogleMerchantCalculations($currency); // Loop through the list of address ids from the callback $addresses = get_arr_result($data[$root]['calculate']['addresses']['anonymous-address']); foreach($addresses as $curr_address) { $curr_id = $curr_address['id']; $country = $curr_address['country-code']['VALUE']; $city = $curr_address['city']['VALUE']; $region = $curr_address['region']['VALUE']; $postal_code = $curr_address['postal-code']['VALUE']; // Loop through each shipping method if merchant-calculated shipping // support is to be provided if(isset($data[$root]['calculate']['shipping'])) { $shipping = get_arr_result($data[$root]['calculate']['shipping']['method']); foreach($shipping as $curr_ship) { $name = $curr_ship['name']; //Compute the price for this shipping method and address id $price = 12; // Modify this to get the actual price $shippable = "true"; // Modify this as required $merchant_result = new GoogleResult($curr_id); $merchant_result->SetShippingDetails($name, $price, $shippable); if($data[$root]['calculate']['tax']['VALUE'] == "true") { //Compute tax for this address id and shipping type $amount = 15; // Modify this to the actual tax value $merchant_result->SetTaxDetails($amount); } if(isset($data[$root]['calculate']['merchant-code-strings'] ['merchant-code-string'])) { $codes = get_arr_result($data[$root]['calculate']['merchant-code-strings'] ['merchant-code-string']); foreach($codes as $curr_code) { //Update this data as required to set whether the coupon is valid, the code and the amount $coupons = new GoogleCoupons("true", $curr_code['code'], 5, "test2"); $merchant_result->AddCoupons($coupons); } } $merchant_calc->AddResult($merchant_result); } } else { $merchant_result = new GoogleResult($curr_id); if($data[$root]['calculate']['tax']['VALUE'] == "true") { //Compute tax for this address id and shipping type $amount = 15; // Modify this to the actual tax value $merchant_result->SetTaxDetails($amount); } $codes = get_arr_result($data[$root]['calculate']['merchant-code-strings'] ['merchant-code-string']); foreach($codes as $curr_code) { //Update this data as required to set whether the coupon is valid, the code and the amount $coupons = new GoogleCoupons("true", $curr_code['code'], 5, "test2"); $merchant_result->AddCoupons($coupons); } $merchant_calc->AddResult($merchant_result); } } $Gresponse->ProcessMerchantCalculations($merchant_calc); break; } case "new-order-notification": { $Gresponse->SendAck(); break; } case "order-state-change-notification": { $Gresponse->SendAck(); $new_financial_state = $data[$root]['new-financial-order-state']['VALUE']; $new_fulfillment_order = $data[$root]['new-fulfillment-order-state']['VALUE']; switch($new_financial_state) { case 'REVIEWING': { break; } case 'CHARGEABLE': { //$Grequest->SendProcessOrder($data[$root]['google-order-number']['VALUE']); //$Grequest->SendChargeOrder($data[$root]['google-order-number']['VALUE'],''); break; } case 'CHARGING': { break; } case 'CHARGED': { break; } case 'PAYMENT_DECLINED': { break; } case 'CANCELLED': { break; } case 'CANCELLED_BY_GOOGLE': { //$Grequest->SendBuyerMessage($data[$root]['google-order-number']['VALUE'], // "Sorry, your order is cancelled by Google", true); break; } default: break; } switch($new_fulfillment_order) { case 'NEW': { break; } case 'PROCESSING': { break; } case 'DELIVERED': { break; } case 'WILL_NOT_DELIVER': { break; } default: break; } break; } case "charge-amount-notification": { //$Grequest->SendDeliverOrder($data[$root]['google-order-number']['VALUE'], // <carrier>, <tracking-number>, <send-email>); //$Grequest->SendArchiveOrder($data[$root]['google-order-number']['VALUE'] ); $Gresponse->SendAck(); break; } case "chargeback-amount-notification": { $Gresponse->SendAck(); break; } case "refund-amount-notification": { $Gresponse->SendAck(); break; } case "risk-information-notification": { $Gresponse->SendAck(); break; } default: $Gresponse->SendBadRequestStatus("Invalid or not supported Message"); break; } I guess that case 'CHARGED' is the one, am I right? Second question, do I need an SSL certificate to receive response from Google Checkout? According to this I do: groups.google.com/group/google-checkout-api-php/browse_thread/thread/10ce55177281c2b0 But I don's see it mentioned anywhere in the official documentation. Thank you.

• How to write Asynchronous LINQ query?

  - by Morgan Cheng

  After I read a bunch of LINQ related stuff, I suddenly realized that no articles introduce how to write asynchronous LINQ query. Suppose we use LINQ to SQL, below statement is clear. However, if the SQL database responds slowly, then the thread using this block of code would be hindered. var result = from item in Products where item.Price > 3 select item.Name; foreach (var name in result) { Console.WriteLine(name); } Seems that current LINQ query spec doesn't provide support to this. Is there any way to do asynchronous programming LINQ? It works like there is a callback notification when results are ready to use without any blocking delay on I/O.

• Matplotlib subplots_adjust hspace so titles and xlabels don't overlap ?

  - by Denis

  With say 3 rows of subplots in matplotlib, xlabels of one row can overlap the title of the next; one has to fiddle with pl.subplots_adjust( hspace ), annoying. Is there a recipe for hspace that prevents overlaps and works for any nrow ? """ matplotlib xlabels overlap titles ?

• Find new messages added to an imap mailbox since I last checked with python libimap2?

  - by vy32

  I am trying to write a program that monitors an IMAP mailbox and automatically copies every new incoming message into an "Archive" folder. I'm using imaplib2 which implements the IDLE command. Here's my basic program: M = imaplib2.IMAP4("mail.me.com") M.login(username,password) lst = M.list() assert lst[0]=='OK' for mbx in lst[1]: print "Mailboxes:",mbx def process(m): print "m=",m res = M.recent() print res M.select('INBOX') M.examine(mailbox='INBOX',callback=process) while True: print "Calling idle..." M.idle() print "back from idle" M.close() M.logout() It prints the mailboxes properly and runs process() when the first change happens to the mailbox. But the response from recent() doesn't make sense to me, and after the first message I never get any other notifications. Anyone know how to do this?

• How to preselect nodes using jsTree jQuery plug-in

  - by Ed Schembor

  I am using the jsTree jQuery plug-in with its "Checkbox" plug-in and using an async http request to lazy-load each level of the tree. All works great, except that I cannot get the tree to pre-select certain nodes after the first level. I am using the "selected" attribute to provide an array of ID's to preselect. ID's in the top level of the tree are correctly pre-selected. However, ID's in lower levels of the tree are not selected when the level loads. Am I missing something? Here is the constructor code: $(sDivID).tree( { data : { async : true, opts : {url : sURL} }, plugins:{ "checkbox" : {three_state : false} }, selected : myArrayOfIDs, ui:{ theme_name : "checkbox", dots : false, animation : 400 }, callback : { beforedata : function(NODE, TREE_OBJ) { return { id : $(NODE).attr("id") || 0, rand : Math.random().toString() } } } } )

• jCarousel: Can you remove all items and rebind to a new collection?

  - by Jim G.

  jCarousel documentation states the following: By passing the callback function itemLoadCallback as configuration option, you are able to dynamically create (li) items for the content. {...} jCarousel contains a convenience method add() that can be passed the index of the item to create and the innerHTML string of the item to be created. My Question: Is it possible to remove all items and rebind to a new collection? BTW: I don't necessarily need a "convenience method" to do this. I'm very open to workarounds. FYI: This strategy doesn't seem to work.

• Hooks...exactly what they are

  - by Ygam

  I have seen hooks in Kohana PHP framework, and they work as some sort of a callback function triggered by a certain event (Kohana's events that is, some sort of method overloading). I have seen hooks in Wordpress, and I don't know what they are or how to use them (just saw them yesterday). I'm looking for events in "non-frameworked" php, I cannot find ones. Do hooks work only in an "event-based" environment? What are they anyway (in general, not just in PHP)? What are they good for if not in an "event-based" environment.

• Converting Asynchronous Programming Model (Begin/End methods) into event-based asynchronous model?

  Let's say I have code that uses the Asynchronous Programming Model, i.e. it provides the following methods as a group which can be used synchronously or asynchronously: public MethodResult Operation(<method params>); public IAsyncResult BeginOperation(<method params>, AsyncCallback callback, object state); public MethodResult EndOperation(IAsyncResult ar); What I want to do is wrap this code with an additional layer that will transform it into the event-driven asynchronous model, like so: public void OperationAsync(<method params>); public event OperationCompletedEventHandler OperationCompleted; public delegate void OperationCompletedEventHandler(object sender, OperationCompletedEventArgs e); Does anyone have any guidance (or links to such guidance) on how to accomplish this?
