  • MacBook's Airport not working from menu bar

    - by not22
    All of the sudden my MacBook doesn't connect to my wireless after waking from sleep. My network shows up at full signal strength and it remembers the password correctly, but I get an error message when I try to connect from the menu bar. The only way I can get on the internet is to go through Network Diagnostics and turn it on there. I don't understand why it works every time through Network Diagnostics and never on it's own or through the airport menu bar. Nothing has been changed or installed or reset on my computer that I know of. Restarting doesn't fix it, nor does turning off the airport card. Any ideas?

  • Quick way to convert Excel sheet to XML

    - by nute
    How do you easily convert an excel file into a XML file? When trying to save as an XML File, it complains that the file does not have an XML mapping. Clicking help brings up pretty complicated stuff about XML Mapping file, XLD and some other acronyms. Why is it so complicated? Lately I've realized that tab delimited, CSV and others are prone to formating issues (comas in a field, new lines, quotes, ...). So I think that XML is a better way to process excel data. Please advise. Maybe a freeway tool?

  • Add a link to a JQueryUI autocomplete item

    - by Tordek
    When a user starts typing on the searchbox, the suggestion page returns the latest item from all collections matching that nama, plus other data. I'd like to show that item (along its image), and a link to "see all items from this collection". I can do (most of) that with the following code: $('#search').autocomplete({ source: function (request, response) { $.ajax({ url: suggesturl, dataType: 'json', data: request, success: function (data) { response(data.map(function (value) { return { 'label': '<img src="' + value.thumbsmall + '" />' + value.name + '<a href="/">More items from this collection...</a>', 'value': value.fullname }; })); } }); }, minLength: 3 }) The problem is that, although the link appears in the box, when it's clicked it gets ignored, and the default select action is executed (the item's value is put into the textbox).

    I don't really get how to use the Curesor parameter in Twitter's API, for an exmaple - here. Am I supposed to make a new API call for each 100 followers? I'd love it if someone could provide a PHP example for getting a full list of followers assuming I have more than 100... Thanks in advance!

  • ASPxGridView POST timeout

    - by Jo Asakura
    Hello all, I have a ASPxGridView with DetailRow in this row there are three additional ASPxGridViews. Each detail ASPxGridView contains EmptyDataRow templates with link to create a new row: <a href="javascript:gridViewDetails1.AddNewRow();">AddNewRecord</a> When master ASPxGridView rows is 1 or 2 then new rows in detail grids adding fine, but if in master ASPxGridView rows about 10 or more then when I clicking on detail grids link to add new row the loading panel appers for unlimited time and FireBug-Net shows that status of POST is timeout and time is about 1 sec. How can I repair it? To AGoodDisplayName: are the detail row gridviews bound to anything? yes of course, inside the details row of master gridView there are 3 another gridView and each of them have a separate ObjectDataSource. Are you expanding more than row at a time? No, I have only one row at time: AllowOnlyOneMasterRowExpanded="true" Can we see some of the mark up? Yep: <asp:ObjectDataSource ID="dsMaster" runat="server" TypeName="..." SelectMethod="..."> </asp:ObjectDataSource> <dxwgv:ASPxGridView ID="gridViewMaster" ClientInstanceName="gridViewMaster" runat="server" DataSourceID="dsMaster"> <Templates> <DetailRow> <%--first of details gridView--%> <asp:ObjectDataSource ID="dsDetail1" runat="server" TypeName="..." SelectMethod="..."> </asp:ObjectDataSource> <dxwgv:ASPxGridView ID="gridViewDetail1" ClientInstanceName="gridViewDetail1" runat="server" DataSourceID="dsDetail1"> <Templates> <EmptyDataRow> <a href="javascript:gridViewDetail1.AddNewRow();">AddNewRecord</a> </EmptyDataRow> </Templates> </dxwgv:ASPxGridView> <%--next others detail gridViews--%> </DetailRow> </Templates> </dxwgv:ASPxGridView>

  • Using SSIS Web Service Task with WCF

    - by Omri
    Hello, I am using SQL Server 2008 SSIS for importing data to the DB and .Net 3.5 SP1 for Creating the WCF service. In the import task I am trying to use the Web Service Task to report to a WCF service. At first I encountered a problem with the WCF WSDL, the Web Service task couldn't get their code generated from the metadata exposed by the WCF service. So I found a blog post at Christian Weyer's Blog talking just about that. Now after I can successfully load a WCF service to the Web Service Task and get the functions generated just fine from the WSDL I encountered another problem. I get an error from the SSIS package at runtime saying that "Method 'ProxyNamespace.MyService.GetData' not found." The full Error is: Error: 0xC002F304 at Web Service Task False, Web Service Task: An error occurred with the following error message: "Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebserviceTaskException: Could not execute the Web method. The error is: Method 'ProxyNamespace.MyService.GetData' not found.. at Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebMethodInvokerProxy.InvokeMethod(DTSWebMethodInfo methodInfo, String serviceName, Object connection) at Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebServiceTaskUtil.Invoke(DTSWebMethodInfo methodInfo, String serviceName, Object connection, VariableDispenser taskVariableDispenser) at Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebServiceTask.executeThread()". I know that the simple solution is going back to regular Web Service, but I really don't want to go there. Thanks, Omri.

  • SQL Query Not Functioning - No Error Message

    - by gamerzfuse
    // Write the data to the database $query = "INSERT INTO staff (name, lastname, username, password, position, department, birthmonth, birthday, birthyear, location, phone, email, street, city, state, country, zip, tags, photo) VALUES ('$name', '$lastname', '$username', '$password', '$position', '$department', '$birthmonth', '$birthday', '$birthyear', '$location', '$phone', '$email', '$street', '$city', '$state', '$country', '$zip', '$tags', '$photo')"; mysql_query($query); var_dump($query); echo '<p>' . $name . ' has been added to the Employee Directory.</p>'; if (!$query) { die('Invalid query: ' . mysql_error()); } Can someone tell me why the above code produced: string(332) "INSERT INTO staff (name, lastname, username, password, position, department, birthmonth, birthday, birthyear, location, phone, email, street, city, state, country, zip, tags, photo) VALUES ('Craig', 'Hooghiem', 'sdf', 'sdf', 'sdf', 'sdf', '01', '01', 'sdf', 'sdf', '', 'sdf', 'sdf', 'sd', 'sdf', 'sdf', 'sd', 'sdg', 'leftround.gif')" Craig has been added to the Employee Directory. But does not actually add anything into the database table "staff" ? I must be missing something obvious here.

  • Lightweight .NET web development?

    - by Breck Fresen
    Fellow stack overflowers, I'm currently working on a project that has a sizable amount of both client and web code. The client code is written in C# and the web piece is written in PHP. Maintaining consistency between the two worlds is becoming cumbersome, and I want consolidate the web code to .Net. The issue is that I hate web development in ASP.Net Web Forms. I want something as raw as PHP, just using C# instead. I've read a little about ASP.Net MVC, but it looks like it abstracts too much of the request logic for my liking. Does anyone know of a lightweight way to allow C# + .Net to handle web requests? Should I be looking more closely at MVC? Thanks in advance, -- Breck

  • Can you preload images in a dojo animation.

    - by asynchronous-challenged
    I have a dojo animation object of about 15 images. I'm also using dojo.fx.chain to link them all together. Right before I create all my dojo.fadeIn's and dojo.fadeOut's I added in some basic javascript to preload each image. My question is: Am I doing this the hard way or is there some function/attr I can set in the animation object to do this?

  • How to change the font size gradually in a UILabel?

    - by Flocked
    Hello, is there a way to change the font size gradually in a UILabel? I tried it with: [UIView beginAnimations:@"foo" context:nil]; [UIView setAnimationDuration:0.8]; uiLabel.font = [UIFont boldSystemFontOfSize:144]; [UIView commitAnimations]; The problem is that the change of the font size happens instantly.

  • Zend php memory memory_limit

    - by RepDetec
    All, I am working on a Zend Framework based web application. We keep encountering out of memory errors on our dev server: Allowed memory size of XXXX bytes exhausted (tried YYYY... We keep increasing memory_limit in php.ini, but it is now up over 1000 megs. What is a normal memory_limit value? What are the usual suspects in php/Zend for running out of memory? We are using the Propel ORM. Thanks for all of the help! Update I cannot reproduce this error in my windows environment. If I set memory_limit low (say 16M), I get the same error, but the "tried to allocate" amount is always something reasonable. For example: (tried to allocate 13344 bytes) If I set the memory very low on the (Fedora 9) server (such as 16M), I get the same thing. consistent, reasonable out of memory errors. However, even when the memory limit is set very high on our server (128M, for example), maybe once a week, I will get an crazy huge memory error: (tried to allocate 1846026201 bytes). I don't know if that might shed any more light onto what is going on. We are using propel 1.5. It sounds like the actual release is going to come out later this month, but it doesn't look like anyone else is having this problem with it anyway. I don't know that Propel is the problem. We are using Zend Server with php 5.2 on the Linux box, and 5.3 locally. Any more ideas? I have a ticket out to get Xdebug installed on the Linux box. Thanks, -rep

  • problem with XAMPP, access forbidden... looking for d:\xampp not c:\xampp

    - by pfunc
    I have been using xampp for a while now without any problem. All of a sudden I start xampp today and I am getting an "Error 403 Access Forbidden" when I try to go to my Localhost. When I check the error logs for apache it says: [Mon Mar 22 21:48:57 2010] [error] [client 127.0.0.1] client denied by server configuration: D:/xaamp This is strange, it should first of all say "C:" and second of all say "Xampp" (not xaamp). Where would I change this is my config files. Have no idea how this could have happened.

  • Optimizing website - minification, sprites, etc...

    - by nivlam
    I'm looking at the product Aptimize Website Accelerator, which is an ISAPI filter that will concatenate files, minify css/javascript, and more. Does anyone have experience with this product, or any other "all-in-one" solutions? I'm interesting in knowing whether something like this would be good long-term, or would manually setting up all the components (integrate YUICompress into the build process, setting up gzip compression, tweaking expiration headers, etc...) be more beneficial? An all-in-one solution like this looks very tempting, as it could save a lot of time if our website is "less than optimal". But how efficient are these products? Would setting up the components manually generate better results? Or would the gap between the all-in-one solution and manually setting up the component be so small, that it's negligible?

  • Does GC guarantee that cleared References are enqueued to ReferenceQueue in topological order?

    - by Dimitris Andreou
    Say there are two objects, A and B, and there is a pointer A.x --> B, and we create, say, WeakReferences to both A and B, with an associated ReferenceQueue. Assume that both A and B become unreachable. Intuitively B cannot be considered unreachable before A is. In such a case, do we somehow get a guarantee that the respective references will be enqueued in the intuitive (topological when there are no cycles) order in the ReferenceQueue? I.e. ref(A) before ref(B). I don't know - what if the GC marked a bunch of objects as unreachable, and then enqueued them in no particular order? I was reviewing Finalizer.java of guava, seeing this snippet: private void cleanUp(Reference<?> reference) throws ShutDown { ... if (reference == frqReference) { /* * The client no longer has a reference to the * FinalizableReferenceQueue. We can stop. */ throw new ShutDown(); } frqReference is a PhantomReference to the used ReferenceQueue, so if this is GC'ed, no Finalizable{Weak, Soft, Phantom}References can be alive, since they reference the queue. So they have to be GC'ed before the queue itself can be GC'ed - but still, do we get the guarantee that these references will be enqueued to the ReferenceQueue at the order they get "garbage collected" (as if they get GC'ed one by one)? The code implies that there is some kind of guarantee, otherwise unprocessed references could theoretically remain in the queue. Thanks

  • Can you bundle a JavaFX jar as an OS X application?

    - by Ianprime0509
    I'm looking for a way to bundle JavaFX applications similarly to the way I can bundle Java applications using Jar Bundler? I really would like to have a custom icon for my program(and the ability to pin it to the Dock). Is there a way to do this now, or do I have to wait for JavaFX to mature in the Java market?

  • Why darcs instead of git?

    - by Ctrl Alt D-1337
    Using pure functional languages can have a lot of benefits over using impure imperatives but low level systems languages will generally allow you to achieve much greater performance especially when they are imperative because it allows you to specify the exact steps in how the cpu should compute the result. If there is ever list of tools where high performance is an absolute must then I would put source version controls systems right at the top of that list and git achieves this very well but performance is not it's only advantage over many other other types of version control systems anyway. The git team are handling the unsafe c code very well and I never worry about my type system or any other features of the language it is written in so why is it that there is a lot of haskell developers that must use darcs when they will only be using the finished product?

  • Oracle Enterprise Manager Logs

    - by idea_
    Hi, I'm attempting to investigate the root cause of the following error which occurs each time a users call an Oracle 10g Forms applet: FRM-92102: A network error has occurred. The Forms Client has attempted to reestablish its connection to the Server 1 time(s) without success. Please check the network connection and try again later. Details... Java Exception: java.io.IOException: Connection failure with 503 This error remained after restarting all my system components: HTTP_Server, OC4J_BI_Forms, Web Cache, Reports Server, etc. The only way to clear this issue was to restart the server entirely. During the downtime, web pages were rendered with the PL/SQL cartridge and being served, so it appears as though this was isolated to forms. Does anybody know which log files may provide clues here? Any help would be much appreciated :) Update: If somebody can provide me with a way or reference to increase the capacity of my web server to minimize these errors, I will accept this as the solution.
