  • discover if mod_rewrite is working (MAMP + codeigniter)

    - by Patrick
    Hi, I'm experimenting (and having problems!) with codeigniter. In particular, links do not work. even if they are correct (eg. http://localhost/ci-book/welcome/cat/3, where welcome is controller, cat the method), they can't be open and chrome says "Oops! This link appears to be broken...." Someone suggested to check that mod_rewrite is working. How can I do that? I'm using Mamp. thanks, P.

  • How to create a registry key in 64bit view from a 32bit application, using native windows api.

    - by George Kas
    I'm kind of a noob when it comes to windows api. I try to create a registry key in the 64bit view of the registry, from a 32bit application using System::Call "${RegCreateKeyEx}(${HKEY_LOCAL_MACHINE}, 'SOFTWARE\SecureW2\Methods\Default\Profiles\26\ConfigData', 0, 'REG_BINARY', 0x00000000L, 0x0100, NULL, .r5, .r6) .r3" (it's nsis scripting), but it doesn't seem to work.

  • css sticky footer without scrolbar

    - by massinissa
    How to do to avoid having the scroller with a sticky footer to the bottom of the page (not bottom of window)? When I remove height=100% from content and sidebar, I'm no more getting the scroller. However, when doing so, my content and sidebar do not fill all the space down to the footer. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta content="text/html; charset=utf-8" http-equiv="Content-Type" /> <title>Untitled 13</title> <style media="all" type="text/css"> * { margin: 0; padding: 0; } html, body, #wrap, form { height: 100%; } #wrap, #footer { width: 750px; margin: 0 auto; } #wrap { background: #cff; } html, body { color: #000; background: #a7a09a; } body > #wrap { height: 100%; min-height: 100%; } form { /*height: auto;*/ min-height: 100%; } #main { background: #000; height:100%; min-height:100%; height: auto !important; */ } #content { height:100%; float: left; padding: 10px; float: left; width: 570px; background: #9c9; } #sidebar { height:100%; float: left; width: 140px; background: #c99; padding: 10px; } #footer { position: relative; margin-top: -100px; height: 100px; clear: both; background: #cc9; bottom: 0; } .clearfix:after { content: "."; display: block; height: 0; clear: both; visibility: hidden; } .clearfix { display: inline-block; } * html .clearfix { height: 1%; } .clearfix { display: block; } #header { /*padding: 5px 10px;*/ background: #ddd; } </style> </head> <body> <form id="form1" runat="server"> <div id="wrap"> <div id="main" class="clearfix"> <div id="header"> <h1>header</h1> </div> <div id="sidebar"> <h2>sidebar</h2> </div> <div id="content"> <h2>main content</h2> </div> </div> </div> <div id="footer"> <h2>footer</h2> </div> </form> </body> </html>

  • Tell jQuery to ignore clicks during an animation sequence

    - by dclowd9901
    I'm in the midst of writing a slideShow app (click a button, and you slide through a list of images) for jQuery, but I've run into a little bug where it will respond to the click() request even while an animation is happening. I'm using the animate() function already, so that isn't staving off the additional animation requests. Any way to program around this?

  • Tutorials for .NET database app using SQLite

    - by ChrisC
    I have some MS Access experience, and had a class on console c++ apps, now I am trying to develop my first program. It's a little C# db app. I have the db tables and columns planned and keyed into VS, but that's where I'm stuck. I'm needing C#/VS tutorials that will guide me on configuring relationships, datatyping, etc, on the db so I can get it ready for testing of the schema. The only tutorials I've been able to find either talk about general db basics (ie, not helping me with VS/C#), or about C# communications with an existing SQL db. Thank you. (In case it matters, I'm using the open source System.Data.SQLite (sqlite.phxsoftware.com) for the db. I chose it over SQL Server CE after seeing a comparison between the two. Also I wanted a server-less version of SQL because this little app will be on other people's computers and I want to to do as little support as possible.)

  • Alternatives to HtmlTextWriter in a System.Web.UI.Control?

    - by Marco Bettiolo
    Hi, Can you use FluentHTML or other alternatives in an web application user control? Can you put a markup file in a System.Web.UI.Control like the System.Web.UI.UserControl but without the burden of the Page object? I would like to reduce the number of lines of the following code: writer.Write(SacrificalMarkupPage.GenerateControlMarkup(new DialogConfirm())); writer.AddAttribute("class", string.Format("ajaxResponse {0}", action)); writer.RenderBeginTag("div"); writer.RenderBeginTag("h4"); writer.WriteEncodedText("Delete selected item?"); writer.RenderEndTag(); //h4 var queryString = new HttpQueryString { {"confirmed", "true"}, {"src", urlReferer.PathAndQuery} }; writer.AddAttribute("href", queryString.MakeQueryString(url).PathAndQuery); writer.AddAttribute("class", "delete"); writer.RenderBeginTag("a"); writer.WriteEncodedText("Yes"); writer.RenderEndTag(); //a.delete writer.WriteEncodedText(" | "); writer.AddAttribute("href", urlReferer.PathAndQuery); writer.AddAttribute("class", "back"); writer.RenderBeginTag("a"); writer.WriteEncodedText("No"); writer.RenderEndTag(); //a.back writer.RenderEndTag(); //div.ajaxResponse.ACTION Thanks

  • C# Training Quizzes

    - by John Sheppard
    Hello there, I have been programming 10 years, mostly in vba and vb.net but I know c# well enough to program what I normally do. I yesterday was applying for a Senior c# position and I did so poorly on the induction test its not funny :) I have always found that for me the best way to learn and recall is via question's and answers (multichoice and short answer). That is, a question is posed and after I answer instant feedback is given as to whether I choose right or wrong and the reasons why. As such I was wondering if anyone knew of or could recommend a C# quiz website. Something like a daily c# quiz to keep my brain up to date and fresh if I'm not always programming in it. Not something wimpy either. Something that does everything. Paying is not an obstacle, id prefer to pay for a good resource than muck around. Thank you

  • Sending html data via $post fails

    - by Neil
    I am using the code below which is fine but when I use the code below that in an attempt to send an html fragment to a processing page to save it as a file but I get nothing. I have tried using ajax with processData set to false ads dataTypes of html, text and xml but nothing works. I can't find anything on this so I guess I must be missing something fairly trivial but I've been at it for 3 hours now. This works $.post("SaveFile.aspx", {f: "test4.htm", c: "This is a test"}, function(data){ alert(data); }, "text"); This fails $.post("SaveFile.aspx", {f: "test4.htm", c: "<h1>This is a test</h1>"}, function(data){ alert(data); }, "text");

  • Learning HTML - The Process.

    - by Gabe
    So, as recommended, I did the W3Schools HTML and XML tutorials this weekend. I understand the basics. Now should I look to get more depth in HTML, or go straight into learning CSS (and try to keep learning html at the same time)? If the first, where should I go for more advanced HTML tutorials?

  • Why is my Lucene index getting locked?

    - by Andrew Bullock
    I had an issue with my search not return the results I expect. I tried to run Luke on my index, but it said it was locked and I needed to Force Unlock it (I'm not a Jedi/Sith though) I tried to delete the index folder and run my recreate-indicies application but the folder was locked. Using unlocker I've found that there are about 100 entries of w3wp.exe (same PID, different Handle) with a lock on the index. Whats going on? I'm doing this in my NHibernate configuration: c.SetListener(ListenerType.PostUpdate, new FullTextIndexEventListener()); c.SetListener(ListenerType.PostInsert, new FullTextIndexEventListener()); c.SetListener(ListenerType.PostDelete, new FullTextIndexEventListener()); And here is the only place i query the index: var fullTextSession = NHibernate.Search.Search.CreateFullTextSession(this.unitOfWork.Session); var fullTextQuery = fullTextSession.CreateFullTextQuery(query, typeof (Person)); fullTextQuery.SetMaxResults(100); return fullTextQuery.List<Person>(); Whats going on? What am i doing wrong? Thanks

  • passing user from UITableView to UIWebView based on selection

    - by ct2k7
    Hello, I'm trying to pass the user on to the interface based on their cell selection in the UITableView, ie, if the user selects cell 1, they are taken to view model 2, containing UIWebView. UIWebView then displays local file, cell1.html. Currently, I've manage to get placeholder using: selectedCellText.text = selectedCell; to display the name of the cell selected. How do I get it to directly pass to the UIWebView, stick UIWebView in the interface and link it using: UIWebView *myWebView = [[UIWebView alloc] initWithFrame:frame]; NSBundle *mainBundle = [NSBundle mainBundle]; NSString *stringUrl = [mainBundle pathForResource:@"selectedCell" ofType:@"html"]; NSURL *baseUrl = [NSURL fileURLWithPath:stringUrl]; NSURLRequest *urlRequest = [NSURLRequest requestWithURL:baseUrl]; [myWebView loadRequest:urlRequest]; My other issue is that some of the cell names have spaces in them, and for simplicity, I'd like to ensure that there are no spaces (actually, will it even work with spaces in the name, I assume with %20 ? Thanks

  • Nice Generic Example that implements an interface.

    - by mbcrump
    I created this quick generic example after noticing that several people were asking questions about it. If you have any questions then let me know. using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Globalization; namespace ConsoleApplication4 { //New class where Type implements IConvertible interface (interface = contract) class Calculate<T> where T : IConvertible { //Setup fields public T X; NumberFormatInfo fmt = NumberFormatInfo.CurrentInfo; //Constructor 1 public Calculate() { X = default(T); } //Constructor 2 public Calculate (T x) { X = x; } //Method that we know will return a double public double DistanceTo (Calculate<T> cal) { //Remove the.ToDouble if you want to see the methods available for IConvertible return (X.ToDouble(fmt) - cal.X.ToDouble(fmt)); } } class Program { static void Main(string[] args) { //Pass value type and call DistanceTo with an Int. Calculate<int> cal = new Calculate<int>(); Calculate<int> cal2 = new Calculate<int>(10); Console.WriteLine("Int : " + cal.DistanceTo(cal2)); //Pass value type and call DistanceTo with an Double. Calculate<double> cal3 = new Calculate<double>(); Calculate<double> cal4 = new Calculate<double>(10.6); Console.WriteLine("Double : " + cal3.DistanceTo(cal4)); //Pass reference type and call DistanceTo with an String. Calculate<string> cal5 = new Calculate<string>("0"); Calculate<string> cal6 = new Calculate<string>("345"); Console.WriteLine("String : " + cal5.DistanceTo(cal6)); } } }

  • Passenger, Apache and avoiding page caching

    - by user38382
    I'm hosting a rack application with passenger and apache. The application is setup to cache the content of each request to the public directory after each request. This allows apache to serve the content directly as a static page for future requests. I would like to tell Apache, presumably through some rewrite rules that any requests with query parameters should not be cached, but instead passed down to the rack application. With a mongrel setup I would just redirect it to the balancer if it meets my rewrite conditions. How do you do the same with passenger?

  • Slower than expected 802.11n wireless network speeds

    - by Ian
    I have two ASUS laptops running Windows 7 connected wirelessly via 802.11n at 150 Mbit, as reported by Task Manager. The router is Netgear WNDR3700. When testing the wireless connection speed using iperf, I'm not getting nearly 150 Mbit: C:\>iperf -c 10.0.0.123 -t 30 ------------------------------------------------------------ Client connecting to 10.0.0.123, TCP port 5001 TCP window size: 8.00 KByte (default) ------------------------------------------------------------ [148] local 10.0.0.116 port 53819 connected with 10.0.0.123 port 5001 [ ID] Interval Transfer Bandwidth [148] 0.0-30.0 sec 41.2 MBytes 11.5 Mbits/sec That's a typical result. Running parallel client threads does not increase the overall total speed. Why would I only be getting 11.5 Mbit on a 150 Mbit connection?

  • setting up multi-mon windows + mac

    - by psychotik
    Ok this is a stretch, but I know of some Windows only software that does this so curious if there is something that does it on the mac too. I have 2 monitors and 2 development machines - a PC and a Mac Mini. I want to be able to view/control both concurrently (one on each monitor). The Mac only has DVI out, the PC has both and my monitors have both. Any suggestions on how I can do it? A solution involving KVM or software (VNC/remoting) is OK... Thanks!

  • Forcing fputcsv to Use Enclosure For *all* Fields

    - by Alan Storm
    When I use fputcsv to write out a line to an open file handle, PHP will add an enclosing character to any column that it believes needs it, but will leave other columns without the enclosures. For example, you might end up with a line like this 11,"Bob ",Jenkins,"200 main st. USA ",etc Short of appending a bogus space to the end of every field, is there any way to force fputcsv to always enclose columns with the enclosure (defaults to a ") character?

  • How does JVM handles dynamic allocation

    - by Nile
    I want to understand how JVM manages heap for the dynamic allocations. Since every java program is invoked as a thread, when does JVM's garbage collector come into play. Also, how things work for javascript's dynamic allocation ?

  • Easiest way to create drop down with database generated options

    - by aarontb
    I'm trying to build a multi-level "game". A randomly generated option (Option1) will trigger other options in a drop down (Option2)...the options in the new drop down will be directly related the to Option1. Option2 will then trigger another drop down with info directly related to Option2 and so forth until reaching OptionEnd...any suggestions, preferably SQL and PHP. Thanks...yeah, I'm a n00b.
