  • Jquery ajax get - how to output data based on condition?

    - by arunas_t
    Hello, there, I have a such piece of code: $("#choose").change(function(){ $.get("get_results.php", {name: $("#choose").val()}, function(data){ if(data !== ""){ $("#results").html(data); }else{ $("#results").html('<strong>Sorry, no records.</strong>'); } }); }); Now the problem is that the first condition ( if(data !== "") ) is always evaluated correctly and executed, but the else clause ('Sorry, no records') never shows up. Can anyone spot the error? Data passed for the else clause is specifically "". Thank You.

  • Can I automate a loop query based on category with the page's title?

    - by jordaninternets
    To explain further, I need to get a page to display posts from a specific category. I want to automate this process so I don't have to make a template for each category. How would I do that? (keep in mind the person I'm building this is for has no coding experience.) The only way I could think off from the top of my head is to use the title or slug. So if the category is named the same thing as the slug, could I filter by category using the slug? Maybe this isn't the best way... what should I do? This is what I came up with, but it doesn't work, I'm sure due to improper use on may part, but I've been pouring over the WP codex and Google with no avail to tell me my problem. <?php $paged = (get_query_var('paged')) ? get_query_var('paged') : 1; $args= array( 'orderby' => 'date', 'order' => 'ASC', 'paged' => $paged, 'category_name' => echo the_title('\'','\'',) ); query_posts($args); ?>

  • Can you have a web application project produce multiple DLLS?

    - by chris
    I have a VS 2008 web application project that is getting large. My structure looks like: - WebRoot - Common/ - Foo/ - Bar/ - Baz/ so I end up with a single Webroot.dll that contains the code for common, foo, bar, and baz. Is it possible to set it so that I end up with common/ in webroot.dll, and code in foo ends up in foo.dll, bar in bar.dll, etc? Update: A couple of suggestions to move some stuff into class libraries. We already have a dozen or so separate class library projects as part of the solution; Foo, Bar and Baz contain nothing but web forms and the associated code-behinds, so moving them into separate class library projects is not feasible.

  • Creating a PHP web page that enables you to reboot the server in Linux?

    - by Stuart
    I want to create a web page that allows the user to initiate a reboot on the linux server. Obviously this would only be avaliable for system admins and would also be controlled by using iptables. Below is a sample of code that I was thinking of using but I wanted to know if there is another way to do this and how also to use this in a web page? Also is there any thing else that I should consider? $command = "cat $pass | su -c 'shutdown -r now'"; $output = array(); try{ echo shell_exec($command); exec($command, $output); system($command, $output); } catch(Exception $e) { print "Unable to shutdown system...\n"; } foreach ($output as $line) { print "$line<br>"; } Thanks in advance.

  • Persisting object changes from child form to parent form based on button press.

    - by Shyran
    I have created a form that is used for both adding and editing a custom object. Which mode the form takes is provided by an enum value passed from the calling code. I also pass in an object of the custom type. All of my controls at data bound to the specific properties of the custom object. When the form is in Add mode, this works great as when the controls are updated with data, the underlying object is as well. However, in Edit mode, I keep two variables of the custom object supplied by the calling code, the original, and a temporary one made through deep copying. The controls are then bound to the temporary copy, this makes it easy to discard the changes if the user clicks the Cancel button. What I want to know is how to persist those changes back to the original object if the user clicks the OK button, since there is now a disconnect because of the deep copying. I am trying to avoid implementing a internal property on the Add/Edit form if I can. Below is an example of my code: public AddEditCustomerDialog(Customer customer, DialogMode mode) { InitializeComponent(); InitializeCustomer(customer, mode); } private void InitializeCustomer(Customer customer, DialogMode mode) { this.customer = customer; if (mode == DialogMode.Edit) { this.Text = "Edit Customer"; this.tempCustomer = ObjectCopyHelper.DeepCopy(this.customer); this.customerListBindingSource.DataSource = this.tempCustomer; this.phoneListBindingSource.DataSource = this.tempCustomer.PhoneList; } else { this.customerListBindingSource.DataSource = this.customer; this.phoneListBindingSource.DataSource = this.customer.PhoneList; } }

  • Are there web search engines with exact match or regex capabilities (for related terms)?

    - by naxa
    Every once in a while I come upon a situation when google's way of searching results in too broad results even if I enclose my search terms in quotation marks. For example now I've tried to find pages that contain both "py.path" and "path.py" without much success. I'm currently aware of engines|sites like Google Code Search for searching actual code and (apparently) Stackoverflow for searching QAs, symbolhound that lets me find symbols, and also wikipedia is often a good place to find lists of symbols. But none of these seems to perform very good in matching exactly on search term pairs (or tuples) and use a broad-enough segment of the web. Is there a website that is good with exactly finding search term pairs? (Why not?)

  • Can i use a Windows 2008 r2 Cluster for file redundancy

    - by JERiv
    I'm researching a sever clustering architecture as a redundancy and backup solution for a client, and something that isn't made clear is whether or not i can use server clustering to replace a file server with backup solution. Forgive my Elementary understanding of server clustering but supposing: 2 Sites (NJ, CA) Identical Servers at each site setup as a Remote Site Cluster nodes with Windows Enterprise server 2008 r2 Services: File, Terminal, AD, and maybe DNS Will the following will be true: Files (including data drives) will be synced between the two servers eliminating the need for third party backup/mirroring software to sync/backup files. Also supposing i use roaming profiles w/ folder redirection; How will client computer in the WAN access their data through the cluster (i.e. will they automatically choose the best route)

  • Which Java Web Framework allows Cross-Domain Javascripting (http proxy) ?

    - by snsd
    So just a quick intro, I am starting to explore Vaadin, and it's absolutely perfect. Previously, I was juggling PHP, Perl, Ruby, and Jquery for designing rich client web application. It didn't work out too well, as I've burnt out from trying to fix cross browser issues (aka get-it-to-work-on-IE-damn-it), handling server-side, client-side, and building a robust communication between the two tier had lot of code not related to application logic....by the time I was burnt out, only tiny bit of application logic was implemented. Vaadin seems like the answer to my problem as it only requires Java and built on top of GWT. However, I am curious how I can incorporate Cross-Domain Javascripting ? Back in LAMP environment, I had a CGI proxy script that loaded external URL, and injected JS into the proxy-loaded page. I used the CGI proxy script, as it rendered Javascript of the external URL well. Is there a class or package for Java or a specific Java web framework similiar to Vaadin that makes this possible ? Thank you.

  • How to access device settings on a S60 symbian based mobile phone?

    - by TheRHCP
    Hello everyone, I recently bought a Sony Ericsson mobile phone which embeds Symbian S60 and I would like to add a missing feature myself. In fact I cannot actually disable Internet connection in an easy way when roaming, which cost me a lot of money last time I moved away ... So I would like to develop a little application that would just replace the actual Internet configuration with a fake configuration to avoid auto-connections. So what I would like to know is how can I access programmatically to my phone settings? I believe that this is possible but I do not really have a clue where to start. I know that Sony Ericsson provides a SDK to run Java applications on its customised JVM but Symbian is also providing a SDK to develop applications for S60 devices in many languages. The real questions is which SDK will provide an API able to access phone settings. This is not well documented so I am asking this question with the hope that someone here already had experience with development for Sony Ericsson/Symbian devices. Thanks.

  • Has anyone properly interpreted HTTP request based on this demo of winpcap?

    - by httpinterpret
    The example is here, and I tried it by changing the filter to tcp and dst port 80 and the following: void packet_handler(u_char *param, const struct pcap_pkthdr *header, const u_char *pkt_data) { .... ip_len = (ih->ver_ihl & 0xf) * 4; tcp_len = (((u_char*)ih)[ip_len + 12] >> 4) * 4; tcpPayload = (u_char*)ih + ip_len + tcp_len; /* start of url - skip "GET " */ url = tcpPayload + 4; end_url = strchr((char*)url, ' '); url_length = end_url - url; final_url = (u_char*)malloc(url_length + 1); strncpy((char*)final_url, (char*)url, url_length); final_url[url_length] = '\0'; printf("%s\n", final_url); .... } But through debug, I see tcpPayload is full of messy code,not supposed "GET ..." stuff. What's wrong with my implement?

  • JSF/HTML - Add a java applet to web page programmaticly.

    - by Ben
    Hi, Theres a web page i'm making which content is very dynamic and so I'm building it from inside the backing bean. I would like to add a java applet to the web page but I could not find the Java Object to correspond to the <applet> tag. So My questions are - What is the JAVA Object for an applet? How did you find it? (For similar future searches) Thanks! P.S - Just to be clear. An example: <h:PanelGroup> would be HtmlPanelGroup as a java object.

  • Can I do a reduce on a list comprehension into two lists, based on two values?

    - by pdknsk
    I've got the following code. sum_review = reduce(add,[book['rw'] for book in books]) sum_rating = reduce(add,[book['rg'] for book in books]) items = len(books) avg_review = sum_review/items avg_rating = sum_rating/items What I'd like is this. sum_review,sum_rating = reduce(add,([book['rw'],[book['rg']) for book in books]) items = len(books) avg_review = sum_review/items avg_rating = sum_rating/items Obviously this doesn't work. How can I solve this redundancy, without a regular loop?

  • In web project can we write core services layer without knowledge of UI ?

    - by Silent Warrior
    I am working on web project. We are using flex as UI layer. My question is often we are writing core service layer separately from web/UI layer so we can reuse same services for different UI layer/technology. So practically is it possible to reuse same core layer services without any changes/addition in API with different kind of UI technologies/layers. For e.g. same core service layer with UI technology which supports synchronized request response (e.g. jsp etc.) and non synchronize or event driven UI technology (e.g Ajax, Flex, GWT etc.) or with multiple devices like (computers, mobiles, pdas etc.). Personally I feel its very tough to write core service layer without any knowledge of UI. Looking for thoughts from other people.

  • Web server which supports removing a file immediately after it has been downloaded once?

    - by Shabbyrobe
    I need a web server that allows me to remove a file after it has been successfully downloaded once. Is there any way to do this with apache? Is there another web server I can use for this task? I had already looked into Tornado for this purpose, but couldn't find a way to get an event to fire as soon as the download finished. the on_connection_close would only fire when I shut down the server. I'd prefer something PHP or Python-based if I have to code it myself.
