  • C++ (And other languages) - Learning from source code examples.

    - by Gabe
    I found that the most effective way for me to learn html and css was to simply find a site, right click, view the source code, and see how it worked. I'm in the process of learning c++ and I think examples/source code to look through would help me a good deal. So, how can I do this? Are there online sites that serve this purpose? Any other recommendations on learning would be great, too.

  • Website Development moving to Image Hosting

    - by Drew
    We are moving over to using Akamai for all of our large static content so far just flash but are planning to include images, css, and js files in that list. I am curious what methods others employ to switch all of their local/relative paths to using an external hosting company. Also, how they continue to develop their site so that developers can make changes in development without it having to be pushed to their external hosting servers.

  • N2 CMS SlidingCurtain control is not visible

    - by Carl Raymond
    I just set up a new N2 site by starting with the MVC 2 Web Application template in Visual Studio, then following the directions in N2 CMS Developer Documentation in the section Integrating with Existing ASP.NET MVC Application. I have the basic site running now, but with one problem: the sliding curtain widget that holds the administrative controls is not visible in the upper right corner (when logged in, of course). I can make it visible the hard way by using Firebug to locate it in the DOM, and then disabling a couple of the CSS positioning elements. Once I do that, it seems to work normally. After I open it that way, I can click the various controls, or close it up (and I see the animation). But then it's off screen again. My master page has the sliding curtain just inside the <body> tag: <body> <n2:SlidingCurtain runat="server"> <n2:ControlPanel runat="server" /> </n2:SlidingCurtain> ... The site.css file generated in the base MVC site doesn't seem to do any positioning that would affect this. Firebug shows that right after by <body> tag, I have this: <div class="sc" id="SC" style="top: -2px; left: -574px;"><div class="scContent"> .... The style for <div class="sc" ...> is element.style { left:-574px; top:-2px; } .sc { background:#FFFFFF none repeat-x scroll 0 0; border-color:#CCCCBB; border-style:none solid solid none; border-width:1px; left:-200px; position:fixed; top:-200px; z-index:990; } If I disable both top: and both left: rules, the widget appears.

  • Sonicwall settings for Polycom TFTP

    - by Michael Glenn
    I'm switching our VoIP phones (Polycom 301s and 501s) to our data network. They were previously segmented to their own network. This means disabling the DHCP on the Trixbox (Asterisk) server and configuring the Sonicwall TZ 210 DHCP to indicate that Trixbox is the TFTP server. The Polycom phones are stating "could not contact boot server". All phones are configured to TFTP and were confirmed working when previously using the Trixbox server for DHCP. Trixbox DHCP is now turned off. I've configured options 66(as String), 128(as IP) and 150(as IP) in DHCP and added them to a TFTP Option Group. I've enabled "Allow BOOTP Clients to use Range" for the Dynamic IP range and assigned the Option Group TFTP as the DHCP Generic Option Group. Any idea what I'm missing? Is there a separate tool to inspect the DHCP response to compare Trixbox to the Sonicwall?

  • How to benchmark apache/nginx setup

    - by Saif Bechan
    I am planning to setup nginx as reverse proxy. I will have apache to deliver my dynamic content, and nginx will deliver the static content. My configuration i have now is just Apache with fastCGI. This gives me no configuration problems and runs great. After I have set up nginx I want to run some benchmarks to see if I really got some performance increases, else i will switch back. Does anyone know how I can benchmark this type of setup? Or maybe someone did this already and have some canned results, I will be glad to hear them.

  • Setting up a proxy for FTP - Windows

    - by RadiantHex
    Hi folks, I have 2 windows machines and a server. 1 is my laptop, the other is a workstation that the IP of which is white-listed on the server. The laptop has a dynamic IP, so the IP cannot be white-listed. I would like to be able to perform FTP transfers from my laptop to the server, while using the workstation as a proxy. Both machines are using Windows 7. Is this possible? Help would be amazing!

  • 3ware RAID in Windows 7

    - by user36484
    Just moved a 3ware 9500S-8 raid card and a few drives from my linux box into my win7 box. Windows Updates picked up the 3ware driver and installed it. After a reboot I checked Disk Management and it shows the array as one solid drive with the correct size. The only issue is that its not assigned a drive letter and when I right click on it my only option is to Convert to Dynamic Disk... From what I've read this is not something I want to do. What are my options?

  • drag and drop working funny when using variable draggables and droppables

    - by Lina
    Hi, i have some containers that contain some divs like: <div id="container1"> <div id="task1" onMouseOver="DragDrop("+1+");">&nbsp;</div> <div id="task2" onMouseOver="DragDrop("+2+");">&nbsp;</div> <div id="task3" onMouseOver="DragDrop("+3+");">&nbsp;</div> <div id="task4" onMouseOver="DragDrop("+4+");">&nbsp;</div> </div> <div id="container2"> <div id="task5" onMouseOver="DragDrop("+5+");">&nbsp;</div> <div id="task6" onMouseOver="DragDrop("+6+");">&nbsp;</div> </div> <div id="container3"> <div id="task7" onMouseOver="DragDrop("+7+");">&nbsp;</div> <div id="task8" onMouseOver="DragDrop("+8+");">&nbsp;</div> <div id="task9" onMouseOver="DragDrop("+9+");">&nbsp;</div> <div id="task10" onMouseOver="DragDrop("+10+");">&nbsp;</div> </div> i'm trying to drag tasks and drop them in one of the container divs, then reposition the dropped task so that it doesn't affect the other divs nor fall outside one of them and to do that i'm using the event onMouseOver to call the following function: function DragDrop(id) { $("#task" + id).draggable({ revert: 'invalid' }); for (var i = 0; i < nameList.length; i++) { $("#" + nameList[i]).droppable({ drop: function (ev, ui) { var pos = $("#task" + id).position(); if (pos.left <= 0) { $("#task" + id).css("left", "5px"); } else { var day = parseInt(parseInt(pos.left) / 42); var leftPos = (day * 42) + 5; $("#task" + id).css("left", "" + leftPos + "px"); } } }); } } where: nameList = [container1, container2, container3]; the drag is working fine, but the drop is not really, it's just a mess! any help please?? when i hardcode the id and the container, then it works beautifully, but as soon as i use id in drop then it begins to work funny! any suggestions??? thanks a million in advance Lina

  • php recursive list help

    - by Jason
    Hi all, I am trying to display a recursive list in PHP for a site I am working on. I am really having trouble trying to get the second level to display. I have a function that displays the contents to the page as follows. function get_menu_entries($content,$which=0) { global $tbl_prefix, $sys_explorer_vars, $sys_config_vars; // INIT LIBRARIES $db = new DB_Tpl(); $curr_time = time(); $db->query("SELECT * FROM ".$tbl_prefix."sys_explorer WHERE preid = '".$which."' && config_id = '".$sys_explorer_vars['config_id']."' && blocked = '0' && startdate < '".$curr_time."' && (enddate > '".$curr_time."' || enddate = '') ORDER BY preid,sorting"); while($db->next_record()){ $indent = $db->f("level") * 10 - 10; $sitemap_vars['break'] = ""; $sitemap_vars['bold'] = ""; if($db->f("level") == 2) { $sitemap_vars['ul_start'] = ""; $sitemap_vars['bold'] = "class='bold'"; $sitemap_vars['ul_end'] = ""; } switch($db->f("link_type")) { case '1': // External Url $sitemap_vars['hyperlink'] = $db->f("link_url"); $sitemap_vars['target'] = ""; if($db->f("link_target") != "") { $sitemap_vars['target'] = "target=\"".$db->f("link_target")."\""; } break; case '2': // Shortcut $sitemap_vars['hyperlink'] = create_url($db->f("link_eid"),$db->f("name"),$sys_config_vars['mod_rewrite']); $sitemap_vars['target'] = ""; break; default: $sitemap_vars['hyperlink'] = create_url($db->f("eid"),$db->f("name"),$sys_config_vars['mod_rewrite']); $sitemap_vars['target'] = ""; break; } if($db->f("level") > 1) { $content .= "<div style=\"text-indent: ".$indent."px;\" ".$sitemap_vars['bold']."><a href=\"".$sitemap_vars['hyperlink']."\" ".$sitemap_vars['target'].">".$db->f("name")."</a></div>\n"; } $content = get_menu_entries($content,$db->f("eid")); } return(''.$content.''); } At the moment the content displays properly, however I want to turn this function into a DHTML dropdown menu. At present what happens with the level 2 elements is that using CSS the contents are indented using CSS. What I need to happen is to place the UL tag at the beginning and /UL tag at the end of the level 2 elements. I hope this makes sense. Any help would be greatly appreciated.

  • Can't connect to sql server 2008 named instance

    - by hcsrpm
    I have sql server 2005 and 2008 running on a server on my local (and very straightforward) network. Using sql management studio 2008 and visual studio 2008, I can connect over the network to the 2005 instance which is the default instance. I can't connect to the 08 instance (named MC08). I can connect to both when logged in to the server. Remote connections have been enabled for MC08 and dynamic ports is turned off (assigned to port 1045). The sql browser service is running as well. This used to work so I'm not sure what has changed. I can't connect using the IP address either. Nothing unusual in the event log either. Any ideas?

  • Random timeouts in IIS7

    - by Cor-Paul
    Hi, I have a weird problem which I think is caused by my IIS7 installation on Vista 64 bit. I have a bunch of AJAX calls and JS dynamic file loads (~30) in a local application, and I get random timeouts (or so it seems) in my browser. In Chrome it looks like the page just stops loading (no HDD activity), in Firefox/Firebug I can see that some of the files are being loaded but they never actually finish. When I reload the page the same occurs, but for (random) other files that must be loaded. When I try to load one of those JS files concurrently (so during the timeout in FF) in another browser, the file loads there. So I am pretty sure the request can be handled by IIS. I am thinking about a limit or so on simultaneous requests from the same browser which is not working correctly, but I am pretty clueless on how to solve this. Does anyone recognize this problem and know a solution? Thanks!

  • How does java permgen relate to code size

    - by brad
    I've been reading a lot about java memory management, garbage collecting et al and I'm trying to find the best settings for my limited memory (1.7g on a small ec2 instance) I'm wondering if there is a direct correlation between my code size and the permgen setting. According to sun: The permanent generation is special because it holds data needed by the virtual machine to describe objects that do not have an equivalence at the Java language level. For example objects describing classes and methods are stored in the permanent generation. To me this means that it's literally storing my class def'ns etc... Does this mean there is a direct correlation between my compiled code size and the permgen I should be setting? My whole app is about 40mb and i noticed we're using 256mb permgen. I'm thinking maybe we're using memory that could be better allocated to dynamic code like object instances etc...

  • hand coding a parser

    - by John Leidegren
    For all you compiler gurus, I wanna write a recursive descent parser and I wanna do it with just code. No generating lexers and parsers from some other grammar and don't tell me to read the dragon book, i'll come around to that eventually. I wanna get into the gritty details about implementing a lexer and parser for a reasonable simple langauge, say CSS. And I wanna do this right. This will probably end up being a series of questions but right now I'm starting with a lexer. Tokenization rules for CSS can be found here. I find my self writing code like this (hopefully you can infer the rest from this snippet): public CssToken ReadNext() { int val; while ((val = _reader.Read()) != -1) { var c = (char)val; switch (_stack.Top) { case ParserState.Init: if (c == ' ') { continue; // ignore } else if (c == '.') { _stack.Transition(ParserState.SubIdent, ParserState.Init); } break; case ParserState.SubIdent: if (c == '-') { _token.Append(c); } _stack.Transition(ParserState.SubNMBegin); break; What is this called? and how far off am I from something reasonable well understood? I'm trying to balence something which is fair in terms of efficiency and easy to work with, using a stack to implement some kind of state machine is working quite well, but I'm unsure how to continue like this. What I have is an input stream, from which I can read 1 character at a time. I don't do any look a head right now, I just read the character then depending on the current state try to do something with that. I'd really like to get into the mind set of writing reusable snippets of code. This Transition method is currently means to do that, it will pop the current state of the stack and then push the arguments in reverse order. That way, when I write Transition(ParserState.SubIdent, ParserState.Init) it will "call" a sub routine SubIdent which will, when complete, return to the Init state. The parser will be implemented in much the same way, currently, having everyhing in a single big method like this allows me to easily return a token when I found one, but it also forces me to keep everything in one single big method. Is there a nice way to split these tokenization rules into seperate methods? Any input/advice on the matter would be greatly appriciated!

  • How to install windows 7 from scratch on a disk which already contains partitions

    - by rangalo
    Hi, I have following partitions on a 1 TB disk. 14 GB UNKNOWN recovery partition 100MB NTFS System Reserved partition for Windows 7 448GB NTFS Windows 7 system partition 468GB NTFS Data partition for windows 7 Now because of the problems mentioned in my other question here I got a brand new windows 7 cd and want to install it from scratch after deleting all the extra partitions. But windows 7 installation doesn't give me such options. It refuses to touch the 14GB Recovery and 100 MB (reserved by previous windows 7) partition. Any ideas ? Note: Because of it is a dynamic disks most of the freely available tools refuse to delete the partitions on the disk. regards.
