    - by Apache
    hi expert, i've written python script to scan wifi and send data to the server, i set interval value, so it keep on scanning and send the data, it read from config.txt file where i set the interval value to scan, i also add yes/no in my config file, so is 'no' it will scan only once and if 'yes' it will scan according to the interval level, my code as below import time,..... from threading import Event, Thread class RepeatTimer(Thread): def __init__(self, interval, function, iterations=0, args=[], kwargs={}): Thread.__init__(self) self.interval = interval self.function = function self.iterations = iterations self.args = args self.kwargs = kwargs self.finished = Event() def run(self): count = 0 while not self.finished.is_set() and (self.iterations <= 0 or count < self.iterations): self.finished.wait(self.interval) if not self.finished.is_set(): self.function(*self.args, **self.kwargs) count += 1 def cancel(self): self.finished.set() def scanWifi(self): #scanning process and sending data done here obj = JW() if status == "yes": t = RepeatTimer(int(intervalTime),obj.scanWifi) t.start() else: obj.scanWifi() once i package my code, its only run when i set my config file set to 'no' where it scan only once, but when i set my config file to 'yes', there is no progress at all, so i found that there is problem with my class RepeatTimer(Timer) once build, but don't know how to solve can anyone help me thanks

  • How can I tell if a set of parens in perl code will act as grouping parens or form a list?

    - by Ryan Thompson
    In perl, parentheses are used for overriding precedence (as in most programming languages) as well as for creating lists. How can I tell if a particular pair of parens will be treated as a grouping construct or a one-element list? For example, I'm pretty sure this is a scalar and not a one-element list: (1 + 1) But what about more complex expressions? Is there an easy way to tell?

  • jQuery + Jeditable - detect when select is changed

    - by Bryan Roth
    I'm using Jeditable for in-place editing. One the controls I am working with has the select type. When a user clicks on the field, the following select control is generated: <div id="status" class="editable_select"> <form> <select name="value"> <option value="Active">Active</option> <option value="Inactive">Inactive</option> </select> <button type="submit">Save</button> <button type="cancel">Cancel</button> </form> </div> What I am trying to figure out is how to use jQuery to detect when that select control is changed, especially since it doesn't have an ID attribute. This is what I have so far, but the event is not getting triggered: $(document).ready(function () { $('#status select').change(function () { alert("Change Event Triggered On:" + $(this).attr("value")); }); });

  • How to properly deal with KVO notifications when an managed object turns into a fault?

    - by dontWatchMyProfile
    From the docs: When Core Data turns an object into a fault, key-value observing (KVO) change notifications (see Key-Value Observing Programming Guide) are sent for the object’s properties. If you are observing properties of an object that is turned into a fault and the fault is subsequently realized, you receive change notifications for properties whose values have not in fact changed. So if an object turns into a fault, Core Data does send KVO notifications for changed properties? So I must always check for isFault == NO before beeing happy about the notification?

  • XML: Check if anything exists between two nodes

    - by sebastian
    Hi there, I need to find out if anything exists between two nodes. My XML looks like this: <event value1="1" value2="2" value3="3" <info="some info here"/> Line 1.</lb> Line 2.</lb></lb> Line 3.</lb> Line 4.</lb> </event> My goal is to convert the </lb> nodes to </br> HTML tags using XSLT. There is one additional requirement to fulfill though. In case there is one </lb> directly following another </lb> I want to output only one </br>. My XSLT looks like this: <xsl:template match="lb"> <xsl:if test="not(preceding-sibling::lb[1])"> <br/> </xsl:if> </xsl:template> The problem with the XSLT above is that it works correctly for line 1 only as the text between both nodes is ignored. Maybe someone here can help.

  • Resizing window causes black strips

    - by Paja
    I have a form, which sets these styles in constructor: this.SetStyle(ControlStyles.AllPaintingInWmPaint, true); this.SetStyle(ControlStyles.UserPaint, true); this.SetStyle(ControlStyles.ResizeRedraw, true); this.SetStyle(ControlStyles.OptimizedDoubleBuffer, true); And I draw some rectangles in Paint event. There are no controls on the form. Hovewer, when I resize the form, there are black strips at right and bottom of the form. Is there any way to get rid of them? I've tried everything, listening for WM_ERASEBKGND in WndProc, manually drawing the form on WM_PAINT, implementing custom double buffer, etc. Is there anything else I could try? I've found this: https://connect.microsoft.com/VisualStudio/feedback/details/522441/custom-resizing-of-system-windows-window-flickers and it looks like it is a bug in DWM, but I just hope I can do some workaround. Please note that I must use double buffering, since I want to draw pretty intense graphic presentation in the Paint event. I develop in C# .NET 2.0, Win7.

  • Scripting Languages vs. Compiled Languages for web development

    - by Austin Hyde
    Though I come from a purely PHP background on the web development side of programming, I have also spent much time with C# and C++ on the desktop. I don't really want to spark any flame wars, but: When should you use scripting languages over compiled languages for website development? (and vice versa) Just to clarify, for the sake of this question, I define a "scripting language" to mean an interpreted language like PHP, Python, or Ruby, and a "compiled language" to mean a strongly typed, compiled language like C#, C++, Java, or VB.

  • Flash As3 Mute Button problems

    - by Lee
    Hey guys, I am trying to create a UI movie clip that can be used across different scenes. It uses variables from the root scope to determine states. When i press the mute button is works fine, however when i try to un-mute things go weird. Sometimes it takes 2 clicks to unmute, sometimes more. It seems random. Muting however seems to work first time.. Any ideas? Main Timeline: var mute:Boolean = false; var playerName = "Fred"; function setMute(vol) { var sTransform:SoundTransform = new SoundTransform(1,0); sTransform.volume = vol; SoundMixer.soundTransform = sTransform; } function toggleMuteBtn(event:Event) { if (mute) { // Sound On, Mute Off mute = false; setMute(1); ui_mc.muteCross_mc.visible = false; } else { // Sound Off, Mute On mute = true; setMute(0); ui_mc.muteCross_mc.visible = true; } } ui_mc Action Script: if (MovieClip(parent).mute == false) { muteCross_mc.visible = false; } mute_btn.addEventListener(MouseEvent.CLICK, MovieClip(parent).toggleMuteBtn);

  • SignalR - Handling disconnected users

    - by guilhermeGeek
    Hy, I'm using the signalR library on a project to handle an notification and chat modules. I've a table on an database to keep a track of online users. The HUB for chat is inheriting IDisconnect where i disconnect the user. After disconnecting the user, i warm the users about that event. At this point, i check if the disconnect user is the client. If it's, then i call an method on HUB to reconnect the user (just update the table). I do this because with the current implementation, once the user closes a tab on the browser it calls the Disconnect task but he could have another tab opened. I've not tested (with larger requests) this module yet, but on my development server it could take a few seconds between the IDisconnect event, and the request from the user to connect again. I'm concerned with my implementation to handle disconnected users from the chat but i can't see another way to improve this. If possible, could someone give me a advice on this, or this is the only solution that i've?

    Hi everybody! Currently, we use programming registration of WCF proxies in Windsor container using WCF Integration Facility. For example: container.Register( Component.For<CalculatorSoap>() .Named("calculatorSoap") .LifeStyle.Transient .ActAs(new DefaultClientModel { Endpoint = WcfEndpoint.FromConfiguration("CalculatorSoap").LogMessages() } ) ); Is there any way to do the same via Windsor XML configuration file. I can't find any sample of this on google. Thanks in advance

  • Differences in ansychronous VB.NET and C#???

    - by Jim Beam
    So I've been posting this week for help with an API that has asynchronous calls. You can view the CODE here: http://stackoverflow.com/questions/2638920/c-asynchronous-event-procedure-does-not-fire With a little more digging, I found out that the API is written in VB.NET and I created a VB.NET example and guess what . . . the asynchronous calls work like a charm. So, now I need to find out why the calls are not firing in the C# code I have. The API being written in VB really shouldn't matter, but again, the VB.NET code works and my C# does not. Is there a problem with the event handler and hows its being declared that causes it to not fire? UPDATE VB Code added Imports ClientSocketServices Imports DHS_Commands Imports DHS Imports Utility Imports SocketServices Class Window1 Public WithEvents AppServer As New ClientAppServer Public Token As LoginToken Private Sub login() Dim handler As New LoginHandler Token = handler.RequestLogin("admin", "admin", localPort:=12000, serverAddress:="127.0.0.1", serverLoginPort:=11000, clienttype:=LoginToken.eClientType.Client_Admin, timeoutInSeconds:=20) If Token.Authenticated Then AppServer = New ClientAppServer(Token, True) AppServer.RetrieveCollection(GetType(Gateways)) End If End Sub Private Sub ReceiveMessage(ByVal rr As RemoteRequest) Handles AppServer.ReceiveRequest If TypeOf (rr.TransferObject) Is Gateways Then MsgBox("dd") End If End Sub Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.Windows.RoutedEventArgs) Handles Button1.Click login() End Sub End Class

  • Am I "wasting" my time learning C and other low level stuff ?

    - by Andreas Grech
    I have just recently started learning C and the reason I did that was because frankly, I consider myself to be of a "less-developer" than the people who know and work with C. Thus I planned to start learning ASM, C, C++ and bought the K&R book and started pushing myself to learn the C Programming Language and up till now I'm doing great...learning about arrays the low level way (ie the pointer + offset thing), pointers and all that and obviously asking questions on stackoverflow for guidance. My problem is that sometimes I get thinking if instead of learning this low level stuff, maybe I should maybe spend more time learning newer, more widely used technologies...basically, more web stuff. Now I am well versed with both C# and ASP.Net and currently that's what I do for a living, but still there exists Microsoft technologies that I haven't quite touched upon...such as ASP.Net MVC, The Entity Framework etc... And those are only Microsoft Technologies...obviously there are other stuff that I would like to touch upon...stuff like Ruby, which would lead me to Ruby on Rails, or Python for Django or even Java and J2EE, or maybe even PHP; ie, basically mainly Web Stuff. Mind you, I did touch upon some of the stuff I mentioned earlier on, such as PHP and Java but I am still not quite versed in them as I am in C# and ASP.Net...but still, I think that by learning other languages that are used in the web environment will broaden my horizons...both as a developer who loves learning, and also Career wise. My point is, am I really using up my time correctly by learning older, lower level stuff? Stuff that for my current line of work, will most probably never use, but still is interesting to know ? To be frankly honest, I am also learning C so that I could, maybe someday, get into Electronics and Micro-controller programming but that is a whole new world for me and, if I choose to go there, will take some time to get adjusted to. And even then, I don't know if I can get a career in working in that line of work. ...but I still wonder about this question over and over...Am I doing the right thing by learning C instead of something (Web-stuff) that will most probably be more useful for me career-wise? I'm sorry for such asking such a long and most probably a boring question, but I feel as if this is the only place where I can ask such a question and get an honest answer from experts in the field. Thank you for your time.

Can you define an endless array in objective c that you can keep pushing items onto, like other lanaguages have a list item. Thanks for any help.

  • window.location.href not working in Safari when using onkeypress

    - by insanepaul
    I'm using an asp textbox and a search button. In Safari if I click the search button i get redirected to the search results page using javascript window.location.href. But strangely the same javascript will not redirect to the page if I press return in the textbox. Using the alert function I can see that window.location.href has the the correct url and the location bar at the top changes from the search page(default.aspx) to the search results url however when I click OK to the alert box the url at the top reverts back to the default.aspx page. It works on ie7/8/firefox/chrome but not safari. Here is my javascript,cs and aspx code: function submitSearchOnEnter(e) { var CodeForEnter = 13; var codeEnteredByUser; if (!e) var e = window.event; if (e.keyCode) codeEnteredByUser = e.keyCode; else if (e.which) codeEnteredByUser = e.which; if (codeEnteredByUser == CodeForEnter) RedirectToSearchPage(); } function RedirectToSearchPage() { var searchText = $get('<%=txtHeaderSearch.ClientID%>').value if (searchText.length) { window.location.href = "Search.aspx?searchString=" + searchText; } } protected void Page_Load(object sender, EventArgs e) { txtHeaderSearch.Attributes.Add("onkeypress", "submitSearchOnEnter(event)"); } <asp:Panel ID="pnlSearch" runat="server" DefaultButton="lnkSearch"> <asp:TextBox ID="txtHeaderSearch" runat="server" CssClass="searchBox"></asp:TextBox> <asp:LinkButton ID="lnkSearch" OnClientClick="RedirectToSearchPage(); return false;" CausesValidation="false" runat="server" CssClass="searchButton"> SEARCH </asp:LinkButton> </asp:Panel> I've tried return false; which doesn't allow me to enter any characters in the search box. I've spent ages online trying to find a solution. Maybe it has something to do with setTimeout or setTimeInterval but it didn't work unless i did it wrong.

  • How to find the leaky faucet that loads into Malloc 32kb

    - by Rob
    I have been messing around with Leaks trying to find which function is not being deallocated (I am still new to this) and could really use some experienced insight. I have this bit of code that seems to be the culprit. Every time I press the button that calls this code, 32kb of memory is additionally allocated to memory and when the button is released that memory does not get deallocated. What I found was that everytime that AVAudioPlayer is called to play an m4a file, the final function to parse the m4a file is MP4BoxParser::Initialize() and this in turn allocates 32kb of memory through Cached_DataSource::ReadBytes My question is, how do I go about deallocating that after it is finished so that it doesn't keep allocating 32kb every time the button is pressed? Any help you could provide is greatly appreciated! - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { //stop playing theAudio.stop; // cancel any pending handleSingleTap messages [NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(handleSingleTap) object:nil]; UITouch* touch = [[event allTouches] anyObject]; NSString* filename = [g_AppsList objectAtIndex: [touch view].tag]; NSString *path = [[NSBundle mainBundle] pathForResource: filename ofType:@"m4a"]; theAudio=[[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL]; theAudio.delegate = self; [theAudio prepareToPlay]; [theAudio setNumberOfLoops:-1]; [theAudio setVolume: g_Volume]; [theAudio play]; }

  • Why there is no open source framework (like Java) for C# application development?

    - by Calvin
    Hi, C# is much more popular than Java in recent years. As a general-purpose programming language, many people feel that C# is better designed than Java. Why until now there is no open source framework for C# application development? Why no one take the initiative to develop a open source framework for C# which is comparable to Java? (Many people say Mono is not a mature framework and should not be used in serious application development.) Calvin

  • TemplateField button causing GridView Invalid Postback

    - by Carter
    Ok, so I've got a template field in a gridview that contains just a simple button... <asp:GridView ID="KeywordsGridView" AllowPaging="false" AutoGenerateColumns="false" BackColor="white" GridLines="None" HeaderStyle-CssClass="Table_Header" RowStyle-CssClass="Table_Style" runat="server"> <Columns> <asp:TemplateField> <ItemTemplate> <asp:Button runat="server" /> </ItemTemplate> </asp:TemplateField> <asp:BoundField DataField="References" SortExpression="References" HeaderText="Total References" /> <asp:BoundField DataField="Keyword" SortExpression="Keyword" HeaderText="Keyword" /> </Columns> </asp:GridView> Whenever I click the button I get the error... Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. I've found a decent amount of articles referencing this issue, including a couple on SO, for example... http://stackoverflow.com/questions/228969/asp-net-invalid-postback-or-callback-argument-event-validation-is-enabled-usi and... http://stackoverflow.com/questions/103560/invalid-postback-or-callback-argument I might just be misunderstanding, but as far as I can tell they don't really help me. How do I get this to go away without setting enableEventValidation="false"?
