• Wanted: How to reliably, consistently select an MKMapView annotation

  - by jdandrea

  After calling MKMapView's setCenterCoordinate:animated: method (without animation), I'd like to call selectAnnotation:animated: (with animation) so that the annotation pops out from the newly-centered pushpin. For now, I simply watch for mapViewDidFinishLoadingMap: and then select the annotation. However, this is problematic. For instance, this method isn't called when there's no need to load additional map data. In those cases, my annotation isn't selected. :( Very well. I could call this immediately after setting the center coordinate instead. Ahh, but in that case it's possible that there is map data to load (but it hasn't finished loading yet). I'd risk calling it too soon, with the animation becoming spotty at best. Thus, if I understand correctly, it's not a matter of knowing if my coordinate is visible, since it's possible to stray almost a screenful of distance and have to load new map data. Rather, it's a matter of knowing if new map data needs to be loaded, and then acting accordingly. Any ideas on how to accomplish this, or how to otherwise (reliably) select an annotation after re-centering the map view on the coordinate where that annotation lives? Clues appreciated - thanks!

• What is the prefered or accepted method for testing proxy settings?

  - by Mike Webb

  I have a lot of trouble with the internet connectivity in the program I am working on and it all seems to spawn from some issue with the proxy settings. Most of the issues at this point are fixed, but the issue I am having now is that my method of testing the proxy settings makes some users wait for long periods of time. Here is what I do: System.Net.WebClient webClnt = new System.Net.WebClient(); webClnt.Proxy = proxy; webClnt.Credentials = proxy.Credentials; byte[] tempBytes; try { tempBytes = webClnt.DownloadData(url.Address); } catch { //Invalid proxy settings //Code to handle the exception goes here } This is the only way that I've found to test if the proxy settings are correct. I tried making a web service call to our web service, but no proxy settings are needed when making the call. It will work even if I have bogus proxy settings. The above method, though, has no timeout member that I can set that I can find and I use the DownloadData as opposed to the DownloadDataAsync because I need to wait til the method is done so that I can know if the settings are correct before continuing on in the program. Any suggestions on a better method or a work around for this method is appreciated. Mike

• Delphi How to wait for socket answer inside procedure?

  - by Astronavigator

  For some specific needs i need to create procedure that waits for socket request (or answer) in dll: TForm1 = class(TForm) ServerSocket1: TServerSocket; ...... procedure MyWaitProc; stdcall; begin Go := false; while not Go do begin // Wating... // Application.ProcessMessages; // Works with this line end; end; procedure TForm1.ServerSocket1ClientRead(Sender: TObject; Socket: TCustomWinSocket); begin MessageBoxA(0, PAnsiChar('Received: '+Socket.ReceiveText), '', MB_OK); Go := true; end; exports MyWaitProc; When I call Application.ProcessMessages everything works fine: application waits for request and then continues. But in my case calling Application.ProcessMessages causes to unlocking main form on host application (not dll's one). When I don't call Application.ProcessMessages application just hangs couse it cannot handle message... So, how to create such a procedure that's wating for socket answer ? Maybe there a way to wait for socket answer without using Application.ProcessMessages ? EDIT I also tried to use TIdTCPServer, for some reasons, the result is the same. TForm1 = class(TForm) IdTCPServer1: TIdTCPServer; ..... procedure MyWaitProc; stdcall; begin Go := false; while not Go do begin // Waiting ... // Application.ProcessMessages; end; end; procedure TForm1.IdTCPServer1Execute(AContext: TIdContext); var s: string; begin s := AContext.Connection.Socket.ReadString(1); AllText := AllText + s; Go := True; end;

• How can I use ToUnicode without breaking dead key support?

  - by Cypherjb

  A similar question has already been asked, so I'm not going to waste time re-explaining it, an existing discussion can be found here: http://stackoverflow.com/questions/1964614/toascii-tounicode-in-a-keyboard-hook-destroys-dead-keys The reason I'm posting a new question however is that I seem to have come across a 'solution', but I'm not quite sure how to implement it. This blog post seems to propose a solution to the problem of ToUnicode killing dead-key support: http://blogs.msdn.com/michkap/archive/2005/01/19/355870.aspx However I'm not sure how to implement the suggested solution. A push in the right direction would be greatly appreciated. To be clear, the part I'm referring to is this: "There are two ways to work around this: 1) You can keep calling ToUnicode with the same info until it is cleared out and then call it one more time to put the state back where it was if you had never typed anything, or 2) You can load all of the keyboard info ahead of time and then when they type information you can look up in your own info cache what the keystrokes mean, without having to call APIs later." I'm not quite sure how to do either of those things (keyboards and internationalization are far from my strong point), so any help would be greatly appreciated. Thanks

• Automatically grow document view of NSScrollView using auto layout?

  - by Monolo

  Is there a simple way to get an NSScrollView to adapt to its document view changing size when using autolayout (the Lion feature)? I have tried to call both setNeedsUpdateConstraints: and setNeedsLayout: on the document view, the clip view and the scroll view, without any results. fittingSize of the document view reports the correct size. An NSPopover in conjunction with an NSViewController handles this nicely, with the popover growing and shrinking as needed, and I was hoping to get a similar simple and robust behaviour with the scroll view. I have checked the documentation for scroll views, but they don't seem to be updated to use autolayout. Edited to clarify: The problem I experience is that the document view, which holds subviews, is not re-sized when the subviews change their size, even if they call invalidateIntrinsicContentSize. The contents of the document view are hence clipped to the original size of the document view as they grow. The document view is created in a nib and set as the scroll view's document view in an awakeFromBib method. What I hoped to obtain was that the document view frame would automatically be adjusted to when its fittingSize changes, and the scrollbars updated accordingly. NSPopover does something similar - provided that the subviews of the content controller's view have the constraints set right and various content hugging values are high enough (higher than the hidden popover window's hight constraint priority, for one).

• Which is better Java programming practice for looping up to an int value: a converted for-each loop

  - by Arvanem

  Hi folks, Given the need to loop up to an arbitrary int value, is it better programming practice to convert the value into an array and for-each the array, or just use a traditional for loop? FYI, I am calculating the number of 5 and 6 results ("hits") in multiple throws of 6-sided dice. My arbitrary int value is the dicePool which represents the number of multiple throws. As I understand it, there are two options: Convert the dicePool into an array and for-each the array: public int calcHits(int dicePool) { int[] dp = new int[dicePool]; for (Integer a : dp) { // call throwDice method } } Use a traditional for loop. public int calcHits(int dicePool) { for (int i = 0; i < dicePool; i++) { // call throwDice method } } I apologise for the poor presentation of the code above (for some reason the code button on the Ask Question page is not doing what it should). My view is that option 1 is clumsy code and involves unnecessary creation of an array, even though the for-each loop is more efficient than the traditional for loop in Option 2. Thanks in advance for any suggestions you might have.

• calll html button onclick event from asp server side login authenticate event

  - by CraigJSte

  Need to programmatically click an html button from a login event (code behind? the html button sends variables to Flash using method: no response - with no postback and uses ExternalInterface API via javascript. Going from SWF ASPX is great, but need to send User.Identity to SWF from ASPX via javascript after authenticate with login event which am having impossible time getting to work... (calling HTML event from Login button) tried scripting in javascript to login event with no luck, possibly because postback clears SWF variables - so perhaps keeping separate (login then html send) would work... Here is my relevant code: function sendToActionScript(value) { swfobject.getObjectById("Property").sendToActionScript(value); } </script> <object ..// SWF File embedded> </object <form id="form1" runat="server"> <asp:Login id="login1" OnAuthenticate="login1_Authenticate"/> </form> <form id="form" onsubmit="return false;"> <input type="text" name="input" id="input" value="" runat="server" /> <button id="btnInput" runat="server" causesvalidation="false" visible="true" style="width: 51px" onclick="sendToActionScript(this.form.input.value);" >Send</button><br /> </form> // CODE BEHIND protected void Login1_Authenticate(object sender, AuthenticateEventArgs e) { // do something to get User Id and Role //bind the string (user or role) to input.value //then call the HTML button onclick event to send it to SWF file. //which I could put in separate function and call from Login_Authenticate } Can anyone help me I am out of ideas.

• Rate limiting a ruby file stream

  - by Matthew Savage

  I am working on a project which involves uploading flash video files to a S3 bucket from a number of geographically distributed nodes. The video files are about 2-3mb each, and we are only sending one file (per node) every ten minutes, however the bandwidth we consume needs to be rate limited to ~20k/s, as these nodes are delivering streaming media to a CDN, and due to the locations we are only able to get 512k max upload. I have been looking into the ASW-S3 gem and while it doesn't offer any kind of rate limiting I am aware that you can pass in a IO Stream. Given this I am wondering if it might be possible to create a rate-limited stream which overrides the read method, adds in the rate limiting logic (e.g. in its simplest form a call to sleep between reads) and then call out to the super of the overridden method. Another option I considered is hacking the code for Net::HTTP and putting the rate limiting into the send_request_with_body_stream method which is using a while loop, but I'm not entirely sure which would be the best option. I have attempted at extending the IO class, however that didn't work at all, simply inheriting from the class with class ThrottledIO < IO didn't do anything. Any suggestions will be greatly appreciated.

• Why is it assumed that send may return with less than requested data transmitted on a blocking socke

  - by Ernelli

  The standard method to send data on a stream socket has always been to call send with a chunk of data to write, check the return value to see if all data was sent and then keep calling send again until the whole message has been accepted. For example this is a simple example of a common scheme: int send_all(int sock, unsigned char *buffer, int len) { int nsent; while(len 0) { nsent = send(sock, buffer, len, 0); if(nsent == -1) // error return -1; buffer += nsent; len -= nsent; } return 0; // ok, all data sent } Even the BSD manpage mentions that ...If no messages space is available at the socket to hold the message to be transmitted, then send() normally blocks... Which indicates that we should assume that send may return without sending all data. Now I find this rather broken but even W. Richard Stevens assumes this in his standard reference book about network programming, not in the beginning chapters, but the more advanced examples uses his own writen (write all data) function instead of calling write. Now I consider this still to be more or less broken, since if send is not able to transmit all data or accept the data in the underlying buffer and the socket is blocking, then send should block and return when the whole send request has been accepted. I mean, in the code example above, what will happen if send returns with less data sent is that it will be called right again with a new request. What has changed since last call? At max a few hundred CPU cycles have passed so the buffer is still full. If send now accepts the data why could'nt it accept it before? Otherwise we will end upp with an inefficient loop where we are trying to send data on a socket that cannot accept data and keep trying, or else? So it seems like the workaround, if needed, results in heavily inefficient code and in those circumstances blocking sockets should be avoided at all an non blocking sockets together with select should be used instead.

• Override ActiveRecord#save, Method Alias? Trying to mixin functionality into save method...

  - by viatropos

  Here's the situation: I have a User model, and two modules for authentication: Oauth and Openid. Both of them override ActiveRecord#save, and have a fair share of implementation logic. Given that I can tell when the user is trying to login via Oauth vs. Openid, but that both of them have overridden save, how do "finally" override save such that I can conditionally call one of the modules' implementations of it? Here is the base structure of what I'm describing: module UsesOauth def self.included(base) base.class_eval do def save puts "Saving with Oauth!" end def save_with_oauth save end end end end module UsesOpenid def self.included(base) base.class_eval do def save puts "Saving with OpenID!" end def save_with_openid save end end end end module Sequencer def save if using_oauth? save_with_oauth elsif using_openid? save_with_openid else super end end end class User < ActiveRecord::Base include UsesOauth include UsesOpenid include Sequencer end I was thinking about using alias_method like so, but that got too complicated, because I might have 1 or 2 more similar modules. I also tried using those save_with_oauth methods (shown above), which almost works. The only thing that's missing is that I also need to call ActiveRecord::Base#save (the super method), so something like this: def save_with_oauth # do this and that super.save # the rest end But I'm not allowed to do that in ruby. Any ideas for a clever solution to this?

• 406 Not Acceptable error when using Jquery $.post in Firefox but not in Safari or Chrome

  - by jlfenaux

  I'm using Jquery (1.3.2) $.post command to trigger an ajax call to a rails server. The code works great on Safari and on Google Chrome (mac), but when I tried it on Firefox (3.5.7), I got a weird '406 Not Acceptable' error. When I look at the headers, it Firefox indicated that it accepted only ' text/javascript' responses. And the response Content-Type was 'text/html; charset=utf-8'. In Chrome the accepted types were 'application/json, text/javascript, /, text/javascript' and the response Content-Type was 'application/json; charset=utf-8'. I tried to force the content type in rails to 'text/javascript' format.json do render :json => @races.to_json, :content_type => 'text/javascript' end The content type is indeed changed in Chrome, but not in Firefox where it remains 'text/html'. Here is the code I used to trigger the ajax call. $.post( "/locator", params, function(data){...}, "json" ); Is there something I can do to make this work in Firefox? Thanks

If "Yes", show the FBStreamDialog. But the BFStreamDialog just flash, then disappear. I don't know why. this is my code. First , click the button " Add feed to your wall". call changeFeed: function. -(IBAction) changeFeed { UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Sporting Summer Festival Monte-Carlo" message:@"Are you attending this concert?" delegate:self cancelButtonTitle:@"No" otherButtonTitles:@"Yes",nil]; [alert show]; alert.tag = 1; self.alertView =alert; [alert release]; } Then, if you choose "YES" button. Call this function: - (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex { if (buttonIndex == 0) { NSLog(@"NO"); } else { NSLog(@"YES"); [self showAddFeed]; } } And this is the showAddFeed function , which is defined in front of "clickButtonAtIndex". -(void)showAddFeed { FBStreamDialog dialog = [[[FBStreamDialog alloc] init] autorelease]; dialog.delegate= self; dialog.userMessagePrompt = @""; [dialog show]; } Just cant work well. I don't know why? Thank you for your help.

• Debug NAudio MP3 reading difference?

  - by Conrad Albrecht

  My code using NAudio to read one particular MP3 gets different results than several other commercial apps. Specifically: My NAudio-based code finds ~1.4 sec of silence at the beginning of this MP3 before "audible audio" (a drum pickup) starts, whereas other apps (Windows Media Player, RealPlayer, WavePad) show ~2.5 sec of silence before that same drum pickup. The particular MP3 is "Like A Rolling Stone" downloaded from Amazon.com. Tested several other MP3s and none show any similar difference between my code and other apps. Most MP3s don't start with such a long silence so I suspect that's the source of the difference. Debugging problems: I can't actually find a way to even prove that the other apps are right and NAudio/me is wrong, i.e. to compare block-by-block my code's results to a "known good reference implementation"; therefore I can't even precisely define the "error" I need to debug. Since my code reads thousands of samples during those 1.4 sec with no obvious errors, I can't think how to narrow down where/when in the input stream to look for a bug. The heart of the NAudio code is a P/Invoke call to acmStreamConvert(), which is a Windows "black box" call which I can't think how to error-check. Can anyone think of any tricks/techniques to debug this?

• Windows Task Scheduler: IAction.QueryInterface() returns an error I cannot find a definition for

  Hello I am attempting to schedule a task (to open an .exe at a specific time) using C++ win32. But at one specific point I am getting an error, I have searched & searched to try & find the definition of this error but I cannot find it? Do you know what this error means: Hexadecimal: 80004003 Decimal: 2147500035 I wont post the whole function because its rather long (unless you may need it to determine the error context?). The code I am using (that causes the error) is the following: // QI for the executable task pointer. hr = action -> QueryInterface( IID_IExecAction, (void**) execAction ); action -> Release(); if( FAILED(hr) ) { printf("QueryInterface call failed for IExecAction: %x %X %u \n", hr, hr, hr ); rootFolder -> Release(); task -> Release(); CoUninitialize(); return false; } The output is: QueryInterface call failed for IExecAction: 80004003 80004003 2147500035

• Mocking an object that uses jni using EasyMock

  - by Visage

  So my class under test has code that looks braodly like this public void doSomething(int param) { Report report = new Report() ...do some calculations report.someMethod(someData) } my intention was to extract the construction of report into a protected method and override it to use a mock object that I could then test to ensure that someMethod had been called with the right data. So far so good. But Report isnt under my control, and to mkae things worse it uses JNI to load a library at runtime. If I do Report report = EasyMock.createMock(Report.class) then EasyMock attempts to use reflection to find out the class members, but this causes an attempt to load the JNI library, which fails (the JNI libraries are only available on UNIX). Im considering two things: a) Introduce a ReportWrapper interface with two implementations, one of which will delegate calls to an real Report (so basically a Proxy), and a second which will basically use a mock object. or b) instead of calling someMethod, call a protected method which will in turn call someMethod that I can override in a testing subclass. Either way it seems nasty. Any better ways?

• I can't get datepicker to work

  - by vikitor

  Hi, I need a field that displays the datepicker. I followed the example given by the JQuery UI documentation and haven't managed to get it to work. My html where I have my text field is: <div class="editor-field"> <input type = "text" name = "DatePublished" id = "Published" /> <%= Html.ValidationMessage("DatePublished" ,"*") %> </div> This HTML is in a partial view, lets call it pv.ascx, and it is called in the main page as a modal box: <div id = "ModalBox"> <% Html.RenderAction("pv", "Example"); %> </div> The thing is, that I try to call the datepicker creation anytime I enter the main page, and I do it in my javascript file app.js: $().ready(function() { var place = window.location.pathname; var placesplit = place.split("/"); //Depending on the location we are on, we execute different subroutines $('#Published').datepicker(); }); But nothing happens when I focus on the text field. What is wrong? Could it be that being called from a partial view it doesn't work? Thank you everyone, vikitor

• Boost causes an invalid block while overloading new/delete operators

  - by user555746

  Hi, I have a problem which appears to a be an invalid memory block that happens during a Boost call to Boost:runtime:cla::parser::~parser. When that global delete is called on that object, C++ asserts on the memory block as an invalid: dbgdel.cpp(52): /* verify block type */ _ASSERTE(_BLOCK_TYPE_IS_VALID(pHead->nBlockUse)); An investigation I did revealed that the problem happened because of a global overloading of the new/delete operators. Those overloadings are placed in a separate DLL. I discovered that the problem happens only when that DLL is compiled in RELEASE while the main application is compiled in DEBUG. So I thought that the Release/Debug build flavors might have created a problem like this in Boost/CRT when overloading new/delete operators. So I then tried to explicitly call to _malloc_dbg and _free_dbg withing the overloading functions even in release mode, but it didn't solve the invalid heap block problem. Any idea what the root cause of the problem is? is that situation solvable? I should stress that the problem began only when I started to use Boost. Before that CRT never complained about any invalid memory block. So could it be an internal Boost bug? Thanks!

• Open a buffer as a vertical split in VIM

  - by alfredodeza

  If you are editing a file in VIM and then you need to open an existing buffer (e.g. from your buffer list: :buffers) how can you open it in a vertical split? I know that you already can open it with a normal split like: :sbuffer N Wehere N is the buffer number you want, however, the above opens that N buffer horizontally, not vertically. I'm also aware that you can change the window placement after opening and have a Vertical Split like so: Ctrl-W H Ctrl-W L Which will vertically split the window to the right or the left. It seems to me that if there is a sbuffer there should be a vsbuffer but that doesn't exist (not that I am aware of) Also, please note that I am not looking for a plugin to solve this question. I know about a wealth of plugins that will allow you to do this. I am sure I might be missing something that is already there. EDIT: In the best spirit of collaboration, I have created a simple Function with a Mapping if someone else stumbles across this issue and do not want to install a plugin: Function: " Vertical Split Buffer Function function VerticalSplitBuffer(buffer) execute "vert belowright sb" a:buffer endfunction Mapping: " Vertical Split Buffer Mapping command -nargs=1 Vbuffer call VerticalSplitBuffer(<f-args>) This accomplishes the task of opening a buffer in a right split, so for buffer 1, you would call it like: :Vbuffer 1

• Pass enum value to method which is called by dynamic object

  - by user329588

  hello. I'm working on program which dynamically(in runtime) loads dlls. For an example: Microsoft.AnalysisServices.dll. In this dll we have this enum: namespace Microsoft.AnalysisServices { [Flags] public enum UpdateOptions { Default = 0, ExpandFull = 1, AlterDependents = 2, } } and we also have this class Cube: namespace Microsoft.AnalysisServices { public sealed class Cube : ... { public Cube(string name); public Cube(string name, string id); .. .. .. } } I dynamically load this dll and create object Cube. Than i call a method Cube.Update(). This method deploy Cube to SQL Analysis server. But if i want to call this method with parameters Cube.Update(UpdateOptions.ExpandFull) i get error, because method doesn't get appropriate parameter. I have already tried this, but doesn't work: dynamic updateOptions = AssemblyLoader.LoadStaticAssembly("Microsoft.AnalysisServices", "Microsoft.AnalysisServices.UpdateOptions");//my class for loading assembly Array s = Enum.GetNames(updateOptions); dynamic myEnumValue = s.GetValue(1);//1 = ExpandFull dynamicCube.Update(myEnumValue);// == Cube.Update(UpdateOptions.ExpandFull) I know that error is in parameter myEnumValue but i don't know how to get dynamically enum type from assembly and pass it to the method. Does anybody know the solution? Thank you very much for answers and help!

• In what order does DOJO handles ajax requests?

  - by mm2887

  Hi, Using a form in a dialog box I am using Dojo in jsp to save the form in my database. After that request is completed using dojo.xhrPost() I am sending in another request to update a dropdown box that should include the added form object that was just saved, but for some reason the request to update the dropdown is executed before saving the form in the database even though the form save is called first. Using Firebug I can see that the getLocations() request is completed before the sendForm() request. This is the code: Add Team sendForm("ajaxResult1", "addTeamForm"); dijit.byId("addTeamDialog").hide(); getLocations("locationsTeam"); </script> function sendForm(target, form){ var targetNode = dojo.byId(target); var xhrArgs = { form: form, url: "ajax", handleAs: "text", load: function(data) { targetNode.innerHTML = data; }, error: function(error) { targetNode.innerHTML = "An unexpected error occurred: " + error; } } //Call the asynchronous xhrGet var deferred = dojo.xhrPost(xhrArgs); } function getLocations(id) { var targetNode = dojo.byId(id); var xhrArgs = { url: "ajax", handleAs: "text", content: { location: "yes" }, load: function(data) { targetNode.innerHTML = data; }, error: function(error) { targetNode.innerHTML = "An unexpected error occurred: " + error; } } //Call the asynchronous xhrGet var deferred = dojo.xhrGet(xhrArgs); } Why is this happening? Is there way to make the first request complete first before the second executes? To reduce the possibilities of why this is happening I tried setting the cache property in xhrGet to false but the result is still the same. Please help!

• Why do IOExceptions occur in ReadableByteChannel.read()

  - by Steffen Heil

  Hi The specification of ReadableByteChannel.read() shows -1 as result value for end-of-stream. Moreover it specifies ClosedByInterruptExceptionas possible result if the thread is interrupted. Now I thought that would be all - and it is most of the time. However, now and then I get the following: java.io.IOException: Eine vorhandene Verbindung wurde vom Remotehost geschlossen at sun.nio.ch.SocketDispatcher.read0(Native Method) at sun.nio.ch.SocketDispatcher.read(SocketDispatcher.java:25) at sun.nio.ch.IOUtil.readIntoNativeBuffer(IOUtil.java:233) at sun.nio.ch.IOUtil.read(IOUtil.java:206) at sun.nio.ch.SocketChannelImpl.read(SocketChannelImpl.java:236) at ... I do not unterstand why I don't get -1 in this case. Also this is not a clean exception, as I cannot catch it without catching any possible IOException. So here are my questions: Why is this exception thrown in the first place? Is it safe to assume that ANY exception thrown by read are about the socket being closed? Is all this the same for write()? And by the way: If I call SocketChannel.close() do I have to call SocketChannel.socket().close() as well or is this implied by the earlier? Thanks, Steffen

• How to define Module and use it in dojo with AMD?

  - by Devdatta Tengshe

  I am maintaining and extending an old project which was pre-AMD. I wish to add an Chart to the application. for this, I have created a js file as follows: define(["dojox/charting/Chart",...."dijit/Dialog","dojo/dom-construct"], function (Chart) { function showDailyChart(data){ //code to show the chart in a dialog } return customModules.singleChart; }); I have saved this file as /customModules/singleChart.js In My main HTML Page, I have added it to the packages as follows: var dojoConfig = { parseOnLoad: true, packages: [....,{"name":"customModules", "location":location.pathname.replace(/\/[^/]+$/, "")+"/modules" } ]}; The function from which I want to call it, is pre-AMD. So I am calling it as follows: dojo.require("customModules.singleChart"); . . . customModules.singleChart.showDailyChart(data); I can see that /customModules/singleChart.js is loaded in the Firebug console as well as Net Tab. However there is no customModules.singleChart object. Strangely enough there is no error either. I have tested this in Firebug, as well as Google Chrome's developer tools. What is the correct way to call an AMD Module using dojo.require? Or is there a better way to do what I need?

• calling .ajax() from an eventHandler c# asp.ent

  - by ibininja

  Good day...! In the code behind (upload.aspx) I have an event that returns the number of bytes being streamed; and as I debug it, it works fine. I wanted to reflect the numbers returned from the eventHandler on a progress bar and this is where I got lost. I tried using jQuery's .ajax() function. this is how I implemented it: In the EventHandler in my code behind I added this code to call the .ajax() function: Page.ClientScript.RegisterStartupScript(this.GetType(), "UpdateProgress", "<script type='text/javascript'>updateProgress();</script>"); My plan is whenever the eventHandler function changes the values of bytes being streamed it calls the javascript function "updateProgress()" The .ajax() function "UpdateProgress()" is as: function updateProgress() { $.ajax({ type: "POST", url: "upload.aspx/GetData", data: "{}", contentType: "application/json; charset=utf-8", dataType: "json", async: true, success: function (msg) { $("#progressbar").progressbar("option", "value", msg.d); } }); } I made sure that the function GetData() is [System.Web.Services.WebMethod] and that it is static as well. so the workflow of what I am trying to implement is as: - Click On Upload button - The Behind code starts executing and EventHandler triggers - The EventHandler calls .ajax() function - The .ajax() function retrieves the bytes being streamed and updates progress bar. When I ran the code; all runs well except that the .ajax() is only executed when upload is finished (and progress bar also updates only when finished upload); even though I call .ajax() function every time in the eventHandler function as reflected above... What am I doing wrong? Am I thinking of this right? is there anything else I should add maybe an updatePanel or something? thank you

  I'm trying to write a unit test that will raise an event on a mock object which my test class is bound to. What I'm keen to test though is that when my test class gets it's eventhandler called it should only call a method on certain values of the eventhandlers parameters. My test seems to pass even if I comment the code that calls ProcessPriceUpdate(price); I'm in VS2005 so no lambdas please :( So... public delegate void PriceUpdateEventHandler(decimal price); public interface IPriceInterface{ event PriceUpdateEventHandler PriceUpdate; } public class TestClass { IPriceInterface priceInterface = null; TestClass(IPriceInterface priceInterface) { this.priceInterface = priceInterface; } public void Init() { priceInterface.PriceUpdate += OnPriceUpdate; } public void OnPriceUpdate(decimal price) { if(price > 0) ProcessPriceUpdate(price); } public void ProcessPriceUpdate(decimal price) { //do something with price } } And my test so far :s public void PriceUpdateEvent() { MockRepository mock = new MockRepository(); IPriceInterface pi = mock.DynamicMock<IPriceInterface>(); TestClass test = new TestClass(pi); decimal prc = 1M; IEventRaiser raiser; using (mock.Record()) { pi.PriceUpdate += null; raiser = LastCall.IgnoreArguments().GetEventRaiser(); Expect.Call(delegate { test.ProcessPriceUpdate(prc); }).Repeat.Once(); } using (mock.Playback()) { test.Init(); raiser.Raise(prc); } }

• Can I configure the ResetPassword in Asp.Net's MembershipProvider?

  - by coloradotechie

  I have an C# asp.net app using the default Sql MembershipProvider. My web.config has a few settings that control how I'm using this Provider: enablePasswordRetrieval="false" enablePasswordReset="true" requiresUniqueEmail="true" passwordFormat="Hashed" minRequiredPasswordLength="5" The problem I'm running into is that when people reset their passwords, it seems the ResetPassword() method returns a password that is longer than I want and has characters that can be confusing (l,1,i,I,0,O). Furthermore, I'm sending my users an email with a plain-text message and an HTML message (I'm using MailMessage with AlternateViews). If the password has unsafe HTML characters in it, when the email clients render the HTML text the password might be different (e.g. the %, &, and < aren't exactly HTML safe). I've looked over the "add" element that belongs in the web.config, but I don't see any extra configuration properties to only include certain characters in the ResetPassword() method and to limit the password length. Can I configure the ResetPassword() method to limit the password length and limit the character set it is choosing from? Right now I have a workaround: I call ResetPassword() to make sure the supplied answer is correct, and then I use a RandomPassword generator I downloaded off the internet to generate a password that I like (without ambiguous characters, HTML safe, and only 8 characters long) and then I call ChangePassword() to change the user's password after I've already reset it. My workaround seems kludgy and I thought it would be better to configure ResetPassword() to do what I want. Thank you~! ColoradoTechie
