  • Why the parent page get refreshed when I click the link to open thickbox-styled form?

    - by user333205
    Hi, all: I'm using Thickbox 3.1 to show signup form. The form content comes from jquery ajax post. The jquery lib is of version 1.4.2. I placed a "signup" link into a div area, which is a part of my other large pages, and the whole content of that div area is ajax+posted from my server. To make thickbox can work in my above arangement, I have modified the thickbox code a little like that: //add thickbox to href & area elements that have a class of .thickbox function tb_init(domChunk){ $(domChunk).live('click', function(){ var t = this.title || this.name || null; var a = this.href || this.alt; var g = this.rel || false; tb_show(t,a,g); this.blur(); return false; });} This modification is the only change against the original version. Beacause the "signup" link is placed in ajaxed content, so I Use live instead of binding the click event directly. When I tested on my pc, the thickbox works well. I can see the signup form quickly, without feeling the content of the parent page(here, is the other large pages) get refreshed. But after transmiting my site files into VHost, when I click the "signup" link, the signup form get presented very slowly. The large pages get refreshed evidently, because the borwser(ie6) are reloading images from server incessantly. These images are set as background images in CSS files. I think that's because the slow connection of network. But why the parent pages get refreshed? and why the browser reloads those images one more time? Havn't those images been placed in local computer's disk? Is there one way to stop that reloadding? Because the signup form can't get displayed sometimes due to slow connection of network. To verified the question, you can access http://www.juliantec.info/track-the-source.html and click the second link in left grey area, that is the "signup" link mentioned above. Thinks!

  • Object reference not set to an instance of an object- Linked List Example

    - by Zoro Roronoa
    I am seeing following errors : Object reference not set to an instance of an object! Check to determinate if the object is null before calling the method! I'am new with C#,and I made a program for Sorted Linked Lists. Here is the code where the error comes! public void Insert(double data) { Link newLink = new Link(data); Link current = first; Link previous = null; if (first == null) { first = newLink; } else { while (data > current.DData && current != null) { previous = current; current = current.Next; } previous.Next = newLink; newLink.Next = current; } } It says that the current referenc is null while (data current.DData && current != null), but I assigned it current = first; Please Help ! The rest is the complete code of the Program! class Link { double dData; Link next=null; public Link Next { get { return next; } set { next = value; } } public double DData { get { return dData; } set { dData = value; } } public Link(double dData) { this.dData = dData; } public void DisplayLink() { Console.WriteLine("Link : "+ dData); } } class SortedList { Link first; public SortedList() { first = null; } public bool IsEmpty() { return (this.first == null); } public void Insert(double data) { Link newLink = new Link(data); Link current = first; Link previous = null; if (first == null) { first = newLink; } else { while (data > current.DData && current != null) { previous = current; current = current.Next; } previous.Next = newLink; newLink.Next = current; } } public Link Remove() { Link temp = first; first = first.Next; return temp; } public void DisplayList() { Link current; current = first; Console.WriteLine("Display the List!"); while (current != null) { current.DisplayLink(); current = current.Next; } } } class SortedListApp { public void TestSortedList() { SortedList newList = new SortedList(); newList.Insert(20); newList.Insert(22); newList.Insert(100); newList.Insert(1000); newList.Insert(15); newList.Insert(11); newList.DisplayList(); newList.Remove(); newList.DisplayList(); } }

  • Can any web-based email program let user paste an image (not link) as part of the email instead of a

    - by Jian Lin
    I think back in the old days, some email programs let users Paste an image right inside the email content. (maybe WinMail or Outlook?) So for example, we can write some text, embed an image, and then write some more text, and embed another image. The recipient will get the email content in the above text-image-text-image order (instead of having all images attached at the end of email) Can any web-based email program do that? Note that the image is not just a link, but a complete file. For example, Gmail lets us paste an image, but it is actually just a link to some web location. Can the actual file content be embedded instead?

  • WordPress > Optimizing a query to show recent posts with a "View All" link when postcount exceeds ma

    - by Scott B
    I have a setting in my theme that allows the site owner to set the maximum number of posts ($maxPosts) to display in a "Recent Posts" menu. I'm using a custom script to generate the recent posts (because the Recent Posts widget does not highlight the current page, which I need for my css). My menu also is set up to display a "View All" link below the post listing, but only if the actual post count is $maxposts I'm trying to work out the best method for getting the post count and comparing it to $maxposts in order to determine whether or not to show a "View All" link. I'm sure there's probably a better way, but here's my code. I'm looking to optimize it to support very large post counts... $cat=get_cat_ID('excludeFromRecentPosts'); $catHidden=get_cat_ID('hidden'); $myquery = new WP_Query(); $myquery->query(array( 'cat' => "-$cat,-$catHidden", 'post_not_in' => get_option('sticky_posts') )); $myrecentpostscount = $myquery->found_posts; if ($myrecentpostscount > 0) { //show the menu if ($myrecentpostscount > $maxPosts) { //show "View All" link } } I really only need to determine if the total post count from the query is greater than the maxPost setting in order to determine whether to show the "View All" link, so I'm wondering if, in the case there are thousands of posts matching the criteria, to avoid performance issues, I don't need to get a count of all of them. I just need to count up until the point of maxPosts + 1, and that's where I'm struggling a bit because the user could elect to make maxPosts = -1 which means they want to show all posts. But this would be impractical, so I would probably set a upper limit of 20...

  • How can I make an AJAX link work once it is moved out of the iFrame?

    - by KcYxA
    Hi, I am using an iFrame with a form that return some content with an AJAX link. I am then moving the returned content out of the iFrame into the main page. However, then the ajax link does not work and the error "Element is null" is created once the link is clicked. How can I move content from the iFrame and still have the AJAX link working? Here's the code returned by the iFrame: <span id="top"> <a id="link8" onclick=" event.returnValue = false; return false;" href="/item_pictures/delete/7"> <img src="/img/delete.bmp"/> </a> <script type="text/javascript"> parent.Event.observe('link8', 'click', function(event) { new Ajax.Updater('top','/item_pictures/delete/3', { asynchronous:true, evalScripts:true, onCreate:function(request, xhr) { document.getElementById("top").innerHTML = "<img src=\"/img/spinner_small.gif\">"; }, requestHeaders:['X-Update', 'top'] }) }, false); </script> </span>

  • Is real-time or synchronous replication possible over WAN link?

    - by johnnyb10
    The company I work for is looking to implement truly real-time file replication with file locking over a WAN link that spans over 2000 miles. We currently have a 16-drive SAN setup in our east coast office. We also have an office out in Colorado that will have the same exact SAN setup. The idea is to have those two SANs contain the same exact data at all times, which will allow us to work with the same data pool, and which will also provide use with an offsite backup solution, should a failure occur on either end. We're running Server 2008. The objective is to enable users in the east coast office to work on files and have those changes be instantly updated on the Colorado SAN as well. We also need there to be file locking so that there will be no conflicts or overwritten changes if users attempt to work on the same file. Is this scenario even possible, at speeds that would make the files usable? And if so, what software would we need to pull this off? As I understand it, DFS-R does not provide file locking, so if we used that, we would need to go with a third-party product like Peerlock. But I don't even know if DFS-R is an option. Can it replicate quickly enough over a WAN link? Can any product? It seems that if we were to use synchronous replication, the programs would be unacceptably slow, as every write would have to wait for confirmation from the other end of the link. But if we used asynchronous replication, what kind of latency would we be looking at? There is a product from GlobalScape called WAFS that claims to provide "File coherence with real-time file locking, file release, and synchronization" and says that "As files are modified, changes are mirrored instantly using intelligent byte-level differencing to minimize the impact on network bandwidth". So this sounds like synchronous replication, but that doesn't even seem possible, given physical limitations such as the speed of light. If anyone has any experience with this kind of setup, or knows whether it's even possible, I'd appreciate your input and suggestions, including recommendations for software that we should check out.

  • Building a Social Networking website, should I have separate servers for certain parts of the site? [closed]

    - by Dylan Cross
    I have been working on building a social networking website, I'm pretty committed to this and I think I have something that could work out. I hope to be launching it January 1st, and so I have a question for server setup and such. Facebook has separate domain names/servers for their photos (and I don't know what else), so I would assume that by doing this it would help spread the server loads out. So I am wondering if it would make a very big difference in speed if I had my main server for basically everything, but had another server and such that the photos would be stored on and access them the same way that facebook does.

  • Most efficient way to store list structure in XML

    - by Mike
    Starting a new project and was planning on storing all of my web content in XML. I do not have access to a database so this seemed like the next best thing. One thing I'm struggling with is how to structure the XML for links (which will later be transformed using XSLT). It needs to be fairly flexible as well. Below is what I started with, but I'm starting to question it. <links> <link> <url>http://google.com</url> <description>Google</description> <link> <link> <url>http://yahoo.com</url> <description>Yahoo</description> <links> <url>http://yahoo.com/search</url> <description>Search</description> </link> <link> </links> That should get transformed into Google Yahoo Search Perhaps something like this might work better. <links> <link href="http://google.com">Google</link> <link href="http://yahoo.com">Yahoo <link href="http://yahoo.com/search">Search</link> </link> </links> Does anyone perhaps have a link that talks about structuring web content properly in XML? Thank you. :)

  • Invert linear linked list

    - by ArtWorkAD
    Hi, a linear linked list is a set of nodes. This is how a node is defined (to keep it easy we do not distinguish between node an list): class Node{ Object data; Node link; public Node(Object pData, Node pLink){ this.data = pData; this.link = pLink; } public String toString(){ if(this.link != null){ return this.data.toString() + this.link.toString(); }else{ return this.data.toString() ; } } public void inc(){ this.data = new Integer((Integer)this.data + 1); } public void lappend(Node list){ Node child = this.link; while(child != null){ child = child.link; } child.link = list; } public Node copy(){ if(this.link != null){ return new Node(new Integer((Integer)this.data), this.link.copy()); }else{ return new Node(new Integer((Integer)this.data), null); } } public Node invert(){ Node child = this.link; while(child != null){ child = child.link; } child.link = this;.... } } I am able to make a deep copy of the list. Now I want to invert the list so that the first node is the last and the last the first. The inverted list has to be a deep copy. I started developing the invert function but I am not sure. Any Ideas? Update: Maybe there is a recursive way since the linear linked list is a recursive data structure. I would take the first element, iterate through the list until I get to a node that has no child and append the first element, I would repeat this for the second, third....

  • Can a Linksys Router be the cause of bad speeds on a 1.5 mbps link.

    - by gramware
    We use a Linksys 5-port router at a smal organization with about 20 employees. We recently acquired a 1.5 mbps fibre link, but sometimes the link goes down and speeds are still low. On enquirey from the ISP, this was part of the response, However there maybe throttling due to the router in place. A Linksys is a low end router and may be unable to carried traffic of up to 1536Kbps. We are in a position to deploy a Cisco 871 router on test for 2 wks to eliminate that possibility. Also kindly advise the destination of the ping results they look to high. How true is that about the router throttling the network and need for a bigger one.

  • When clicking an irc:// link, a new instance of chatzilla opens instead of the existing one being used.

    - by WebDevHobo
    That is my problem in a nutshell. I'm running Win7 32-bit. I have chatzilla on XulRunner, so not as the Firefox add-on. When I clock any irc:// link, a new instance of Chatzilla will be started. I have a lot of startup-commands set, so all those will be executed. I stop the new instance before it takes off, but this is rather annoying. Firefox application setting just link to the path where the executable is, with no option to set any command-line stuff to make the existing instance be used. Is there any firefox or windows setting that I can manipulate, so that when firefox calls chatzilla.exe, the existing instance is used instead of a new one opened?

  • Building new GIS Workstation - is it worth upgrading to a workstation GPU?

    - by bsigrist
    We are currently building a machine from scratch to act as a GIS workstation. The primary software used is ESRI's ArcGIS and we are mainly working with vector data using raster data only for contextual background imagery. In the past I have built a GIS machine and used a consumer grade gaming GPU (Nvidia 9800GT) and found it to perform fine. However, I have always wondered if I would have been better off equipping it with a workstation GPU such as a Quadro series. Would a workstation GPU make a noticeable difference doing 2D GIS operations or should I save money on the build and equip it with another 9800GT?

  • How would i go about showing the closest paragraph element to a unique link with jQuery?

    - by Nike
    The title is a bit rusty, sorry about that. Now let me explain what i'm trying to do. I have a few listed items, like this: <li> <a id="toggle" class="0"><h4>ämne<small>2010-04-17 kl 12:54</small></h4></a> <p id="meddel" class="0">text</p> </li> <li class='odd'> <a id="toggle" class="1"><h4>test<small>2010-04-17 kl 15:01</small></h4></a> <p id="meddel" class="1">test meddelande :) [a]http://youtube.com[/a]</p> </li> The function i'm trying to achieve, is that when a user clicks a "toggle" link (the h4 text), i want the paragraph element below it to fade in. I thought of the idea of giving both the toggle link and the paragraph the same class, and then somehow make it get the paragraph with the same class as the toggle link clicked, and show it? But i'm not entirely sure how to do that either, and tbh, it doesn't sound like the greatest idea, but maybe that's the only way? I don't know... Is there some way to just simply get the nearest paragraph (below the link) with the id "meddel" and fade it in? That sounds a bit easier... I hope you can at least give me a few hints. Thanks in advance, -Nike

  • Can you link an NTFS junction point to a directory on a Network Attached Storage?

    - by Zachary Burt
    I'm using Windows, and I want to use Dropbox to back up a folder outside my Dropbox directory. So I want to create a junction point from my target directory to my Dropbox folder. Accoding to the Wikipedia article on NTFS junction points, which the Dropbox answer links to: "Junction points can only link to directories on a local volume; junction points to remote shares are unsupported." I am looking to link to a directory on networked attached storage, which would not be a local volume, I believe. What should I do?

  • I want a hyperlink to open a browser tab, then all subsequent link clicks go to the same tab

    - by rossmcm
    I suspect I'm out of luck on this one, but here goes... Say I have a CHM help file that has http:// hyperlinks embedded in the help pages. When the user clicks on a hyperlink of the style: <a href="http://www.example.com" target="_blank">click here!</a> a browser window is opened and the target web page is displayed. If a browser is already open a new tab is created and the target displayed in that. If the user clicks on another link (or the same link) another browser window/tab opens, and so on. Is there any way I can force all clicks of the links to go to the same tab/browser window?

  • Finding part of a string that a user has sent via POST

    - by blerh
    My users can send links from popular file hosts like Rapidshare, Megaupload, Hotfile and FileFactory. I need to somehow find out what filehost they sent the link from and use the correct class for it appropriately. For example, if I sent a Rapidshare link in a form on my web page, I need to somehow cycle through each file host that I allow until I find the text rapidshare.com, then I know the user has posted a Rapidshare link. Perhaps a PHP example: switch($_POST['link']) { case strstr($_POST['link'], 'rapidshare.com'): // the link is a Rapidshare one break; case strstr($_POST['link'], 'megaupload.com'): // the link is a Megaupload one break; case strstr($_POST['link'], 'hotfile.com'): // the link is a Hotfile one break; case strstr($_POST['link'], 'filefactory.com'): // the link is a Filefactory one break; } However, I know for a fact this isn't correct and I'd rather not use a huge IF statement if I can help it. Does anyone have any solution to this problem? If you need me to explain more I can try, English isn't my native language so it's kinda hard. Thanks all.

  • How to output multicolumn html without "widows"?

    - by user314850
    I need to output to HTML a list of categorized links in exactly three columns of text. They must be displayed similar to columns in a newspaper or magazine. So, for example, if there are 20 lines total the first and second columns would contain 7 lines and the last column would contain 6. The list must be dynamic; it will be regularly changed. The tricky part is that the links are categorized with a title and this title cannot be a "widow". If you have a page layout background you'll know that this means the titles cannot be displayed at the bottom of the column -- they must have at least one link underneath them, otherwise they should bump to the next column (I know, technically it should be two lines if I were actually doing page layout, but in this case one is acceptable). I'm having a difficult time figuring out how to get this done. Here's an example of what I mean: Shopping Link 3 Link1 Link 1 Link 4 Link2 Link 2 Link 3 Link 3 Cars Link 1 Music Games Link 2 Link 1 Link 1 Link 2 News As you can see, the "News" title is at the bottom of the middle column, and so is a "widow". This is unacceptable. I could bump it to the next column, but that would create an unnecessarily large amount of white space at the bottom of the second column. What needs to happen instead is that the entire list needs to be re-balanced. I'm wondering if anyone has any tips for how to accomplish this, or perhaps source code or a plug in. Python is preferable, but any language is fine. I'm just trying to get the general concept down.

  • XPath ordered priority attribute search

    - by user94000
    I want to write an XPath that can return some link elements on an HTML DOM. The syntax is wrong, but here is the gist of what I want: //web:link[@text='Login' THEN_TRY @href='login.php' THEN_TRY @index=0] THEN_TRY is a made-up operator, because I can't find what operator(s) to use. If many links exist on the page for the given set of [attribute=name] pairs, the link which matches the most left-most attribute(s) should be returned instead of any others. For example, consider a case where the above example XPath finds 3 links that match any of the given attributes: link A: text='Sign In', href='Login.php', index=0 link B: text='Login', href='Signin.php', index=15 link C: text='Login', href='Login.php', index=22 Link C ranks as the best match because it matches the First and Second attributes. Link B ranks second because it only matches the First attribute. Link A ranks last because it does not match the First attribute; it only matches the Second and Third attributes. The XPath should return the best match, Link C. If more than one link were tied for "best match", the XPath should return the first best link that it found on the page.

  • Building a network at home, what cables to use (if any)?

    - by Faruz
    My house is currently in ruins and am building it. While doing so, I wanted to design a home network. My main objectives are surfing and HD streaming. The house is one-level, 100 sq/m (about 300 sq/ft), and one of the rooms is a safety room with Reinforced concrete walls. About a year ago, when I started planning, I thought about putting Cat 6 STP cables in the walls and create network points in the rooms. Should I use STP or FTP? I heard that STP is a problem regarding connectors and stuff. Is it really beneficial? Will it work OK if I transfer the wire together with the telephone line? Should I maybe go with WLan and count on 802.11n to enable me to stream HD across the house? is 802.11n that good?

  • Building SL4 + RIAServices app takes too long on VS2010.

    - by adlanelm
    Got a Win7 box with VS2010 Premium installed on it. Building desktop apps works just fine. But we got this solution with 15 SL4 and 21 desktop projects... Building the SL part of it takes too long. This is very irritating and encourages to drop TDD since every time I run a test it takes ~3 seconds for msbuild to find out that nothing changed and the project should be skipped. The projects are very small and there's nothing fancy in them and we hadn't any problems before we switched from VS2008+SL3. I've heard people complaining abound VS2010 speed in general, but nothing about SL4 build time. Is anyone experiencing same problems and is there any workaround for this?

  • MS Excel: Can I link images using a relative path?

    - by Port Islander 2009
    I am working on an MS Excel document that contains a lot of (around 200) images. They are currently saved within the document, so the file becomes huge and working gets very slow. Linking the pictures without saving them works very well - I now have the Excel document and a folder "pictures" next to it that contains all my image files. However, when I move the document and the folder to a new location, all my pictures disappear. This seems to be because Excel saves the link information as absolute paths. (Update: Actually, according to this thread, Excel stores the link information as relative paths as well. Now I really don't know why my links break down..) Is there a convenient way to save them as relative paths or have Excel automatically update the path information? Update: It's important that the images get displayed on the sheet and can be printed. I am working with Microsoft Excel for Mac 2008 and 2011. I really appreciate your help.

  • How to ALWAYS link an image in MS Word 2010 instead of embedding it?

    - by grunwald2.0
    I want to only link, not embed, pictures in my Word document. Yet I got a lot of images to insert! And I want to spare me the additional click into the dropdown menu one and for all, so the question is, is there any way to set "link image(s)" as default? Because I didn't find anything in the Word settings, only totally useless detail settings. This "detail" has been overseen by Microsoft it seems! :( I would provide you with a screenshot, but it would be German anyways. I think the guys who use image linking in Word since v2007, will know what I mean. Thank you in advance! Best regards

  • How do I get MSBuild Task to generate XML Documents when building a solution?

    - by toba303
    I have a solution with lots of projects. Each project is configured to generate the XML documentation file when building in Debug-Mode (which is default). That works when I build in Visual Studio 2008. In my build script on my integration server I advise MSBuild to build the whole solution, but it won't generate the documentation files. What can I do? I already tried to explicitly give the Debug-Condition to the build process, but it makes no difference. <Target Name="BuilSolution"> <MSBuild Projects="C:\Path\To\MySolution.sln" targets="Build" Properties="SolutionConfigurationPlatforms='Debug|Any CPU'"/> </Target> There seem to be some ideas to solve this problem when building single projects, but I can't afford to do this, so I need a hint for doing it this way. Thanks in advance!
