    - by steve
    i have bought a template that have built in contact form problem is that it submits every thing except "company" name i have spent few hours messing around with it but cant get to work it. if you can point me to some solution i would be greatful thanks in advance this is contact form <form action="php/contact.php" method="post" id="contactform"> <ol> <li> <label for="name">your name <span class="red">*</span></label> <input id="name" name="name" class="text" /> </li> <li> <label for="email">Your email <span class="red">*</span></label> <input id="email" name="email" class="text" /> </li> <li> <label for="company">Company Name</label> <input id="company" name="company" class="text" /> </li> <li> <label for="subject">Subject</label> <input id="subject" name="subject" class="text" /> </li> <li> <label for="message">Message <span class="red">*</span></label> <textarea id="message" name="message" rows="6" cols="50"></textarea> </li> <li class="buttons"> <input type="image" name="imageField" id="imageField" src="images/button.jpg" /> </li> </ol> </form> this is java script <script type="text/javascript"> // <![CDATA[ jQuery(document).ready(function(){ $('#contactform').submit(function(){ var action = $(this).attr('action'); $.post(action, { name: $('#name').val(), email: $('#email').val(), company: $('#company').val(), subject: $('#subject').val(), message: $('#message').val() }, function(data){ $('#contactform #submit').attr('disabled',''); $('.response').remove(); $('#contactform').before('<p class="response">'+data+'</p>'); $('.response').slideDown(); if(data=='Thanks for your message, will contact you soon.') $('#contactform').slideUp(); } ); return false; }); }); // ]]> </script> this is php script if(!$_POST) exit; $email = $_POST['email']; //$error[] = preg_match('/\b[A-Z0-9._%-]+@[A-Z0-9.-]+.[A-Z]{2,4}\b/i', $POST['email']) ?

  • iOS Switching an embedded view in storyboard

    - by Coyote6
    I have been trying to figure this out all day and I know it should be able to be done, but being new to iOS development using Objective-C and not Appcelerator I'm having newbie issues. What I am trying to accomplish is to have an embedded view in one of my other views, but to be able to switch which view is embedded through programming. I am using storyboards. When I tried to use the view container it displays the attached view, but I cannot attach multiple views to the container in the storyboard. I drew up an image, but to my annoyance I cannot post an image on here because I don't have enough "rep" points, so I posted it on my site: http://static.c6gx.com/images/iphone-embedded-views-diagram.jpg Later on I would like what appears to be a push segue, within that view container, but first I just want to be able to switch between embedded view 1, 2, 3, etc. Am I supposed to be using a view container to accomplish this, or some other type of controller? Then how would I call the transition to change the view? Thank you for any help you can provide.

  • GetAcceptExSockaddrs returns garbage! Does anyone know why?

    - by David
    Hello, I'm trying to write a quick/dirty echoserver in Delphi, but I notice that GetAcceptExSockaddrs seems to be writing to only the first 4 bytes of the structure I pass it. USES SysUtils; TYPE BOOL = LongBool; DWORD = Cardinal; LPDWORD = ^DWORD; short = SmallInt; ushort = Word; uint16 = Word; uint = Cardinal; ulong = Cardinal; SOCKET = uint; PVOID = Pointer; _HANDLE = DWORD; _in_addr = packed record s_addr : ulong; end; _sockaddr_in = packed record sin_family : short; sin_port : uint16; sin_addr : _in_addr; sin_zero : array[0..7] of Char; end; P_sockaddr_in = ^_sockaddr_in; _Overlapped = packed record Internal : Int64; Offset : Int64; hEvent : _HANDLE; end; LP_Overlapped = ^_Overlapped; IMPORTS function _AcceptEx (sListenSocket, sAcceptSocket : SOCKET; lpOutputBuffer : PVOID; dwReceiveDataLength, dwLocalAddressLength, dwRemoteAddressLength : DWORD; lpdwBytesReceived : LPDWORD; lpOverlapped : LP_OVERLAPPED) : BOOL; stdcall; external MSWinsock name 'AcceptEx'; procedure _GetAcceptExSockaddrs (lpOutputBuffer : PVOID; dwReceiveDataLength, dwLocalAddressLength, dwRemoteAddressLength : DWORD; LocalSockaddr : P_Sockaddr_in; LocalSockaddrLength : LPINT; RemoteSockaddr : P_Sockaddr_in; RemoteSockaddrLength : LPINT); stdcall; external MSWinsock name 'GetAcceptExSockaddrs'; CONST BufDataSize = 8192; BufAddrSize = SizeOf (_sockaddr_in) + 16; VAR ListenSock, AcceptSock : SOCKET; Addr, LocalAddr, RemoteAddr : _sockaddr_in; LocalAddrSize, RemoteAddrSize : INT; Buf : array[1..BufDataSize + BufAddrSize * 2] of Byte; BytesReceived : DWORD; Ov : _Overlapped; BEGIN //WSAStartup, create listen socket, bind to port 1066 on any interface, listen //Create event for overlapped (autoreset, initally not signalled) //Create accept socket if _AcceptEx (ListenSock, AcceptSock, @Buf, BufDataSize, BufAddrSize, BufAddrSize, @BytesReceived, @Ov) then WinCheck ('SetEvent', _SetEvent (Ov.hEvent)) else if GetLastError <> ERROR_IO_PENDING then WinCheck ('AcceptEx', GetLastError); {do WaitForMultipleObjects} _GetAcceptExSockaddrs (@Buf, BufDataSize, BufAddrSize, BufAddrSize, @LocalAddr, @LocalAddrSize, @RemoteAddr, @RemoteAddrSize); So if I run this, connect to it with Telnet (on same computer, connecting to localhost) and then type a key, WaitForMultipleObjects will unblock and GetAcceptExSockaddrs will run. But the result is garbage! RemoteAddr.sin_family = -13894 RemoteAddr.sin_port = 64 and the rest is zeroes. What gives? Thanks in advance!

  • Noob - Cycle through stored names and skip blanks

    - by ActiveJimBob
    NOOB trying to make my code more efficient. On scroll button push, the function 'SetName' stores a number to integer 'iName' which is index against 5 names stored in memory. If a name is not set in memeory, it skips to the next. The code works, but takes up a lot of room. Any advice appreciated. Code: #include <string.h> int iName = 0; int iNewName = 0; BYTE GetName () { return iName; } void SetName (int iNewName) { while (iName != iNewName) { switch (byNewName) { case 1: if (strlen (memory.m_nameA) == 0) new_name++; else iName = iNewName; break; case 2: if (strlen (memory.m_nameB) == 0) new_name++; else iName = iNewName; break; case 3: if (strlen (memory.m_nameC) == 0) new_name++; else iName = iNewName; break; case 4: if (strlen (memory.m_nameD) == 0) new_name++; else iName = iNewName; break; case 5: if (strlen (memory.m_nameE) == 0) new_name++; else iName = iNewName; break; default: iNewName = 1; break; } // end of case } // end of loop } // end of SetName function void main () { while(1) { if (Button_pushed) SetName(GetName+1); } // end of infinite loop } // end of main

  • Trouble with pointers and references in C++

    - by KingNestor
    I have a PolygonList and a Polygon type, which are std::lists of Points or lists of lists of points. class Point { public: int x, y; Point(int x1, int y1) { x = x1; y = y1; } }; typedef std::list<Point> Polygon; typedef std::list<Polygon> PolygonList; // List of all our polygons PolygonList polygonList; However, I'm confused on reference variables and pointers. For example, I would like to be able to reference the first Polygon in my polygonList, and push a new Point to it. So I attempted to set the front of the polygonList to a Polygon called currentPolygon like so: Polygon currentPolygon = polygonList.front(); currentPolygon.push_front(somePoint); and now, I can add points to currentPolygon, but these changes end up not being reflected in that same polygon in the polygonList. Is currentPolygon simply a copy of the Polygon in the front of polygonList? When I later iterate over polygonList all the points I've added to currentPolygon aren't shown. It works if I do this: polygonList.front().push_front(somePoint); Why aren't these the same and how can I create a reference to the physical front polygon rather than a copy of it?

  • Accessing global variables of custom controls in ASP.NET

    - by CL4NCY
    Hi, I have built lots of custom asp.net controls which work really well separately but I want to somehow allow global access to all their variables from anywhere on the page. I have a central control called the ContentManager which I can use to store these variables. The problem I have is that all the controls are bound at different times so I only want the variables available after they're bound. For example I have many custom repeaters on the page which when bound I want to add a reference in the content manager so all their variables are then available to use. <Custom:ContentManager ID="cm" runat="server"/> <Custom:Repeater ID="r1" runat="server"/> <Custom:Repeater ID="r2" runat="server"/> <Custom:Repeater ID="r3" runat="server"/> Then I want a tag which can access all variables from any of these controls. <%= cm.controls["r1"].Items[0]["name"] %> The problem with this is that the variable isn't available until the repeater is bound so I might need to use events to push out the value to tags on the page like so: <Custom:Var ID="v1" control="r1" value="Items[0]["name"]" runat="server"/> Is this possible or can you recommend a better approach?

  • Deploying a Rails app on an Ubuntu server using Git

    - by NudeCanalTroll
    I'm completely new to Linux, but today I find myself setting up a server (Ubuntu 10.04 LTS lucid) from scratch to host a Rails application. Anyway, I managed to get a Rails app up and running on the server itself, but I had to scrap that because I want to use Git. So I setup a git repository on the server, then pushed all the code from my local machine to the repository. Buuuut, of course Git doesn't actually store the files themselves in the repository -- all the code for my Rails app is now only on my local machine. How am I supposed to tell the server to host that? Right now my solution is to have the server use git to pull the code from its own repository. That's the code I'll host for all the world to see. In order to update the code, I guess I'll have to do something like this: Update the code on my local machine. Do some git adds, git commits, and a git push. On the server, do a git pull to update the code. So my question is, am I doing this the right way? enter code here

  • Performance of C# method polymorphism with generics

    - by zildjohn01
    I noticed in C#, unlike C++, you can combine virtual and generic methods. For example: using System.Diagnostics; class Base { public virtual void Concrete() {Debug.WriteLine("base concrete");} public virtual void Generic<T>() {Debug.WriteLine("base generic");} } class Derived : Base { public override void Concrete() {Debug.WriteLine("derived concrete");} public override void Generic<T>() {Debug.WriteLine("derived generic");} } class App { static void Main() { Base x = new Derived(); x.Concrete(); x.Generic<PerformanceCounter>(); } } Given that any number of versions of Generic<T> could be instantiated, it doesn't look like the standard vtbl approach could be used to resolve method calls, and in fact it's not. Here's the generated code: x.Concrete(); mov ecx,dword ptr [ebp-8] mov eax,dword ptr [ecx] call dword ptr [eax+38h] x.Generic<PerformanceCounter>(); push 989A38h mov ecx,dword ptr [ebp-8] mov edx,989914h call 76A874F1 mov dword ptr [ebp-4],eax mov ecx,dword ptr [ebp-8] call dword ptr [ebp-4] The extra code appears to be looking up a dynamic vtbl according to the generic parameters, and then calling into it. Has anyone written about the specifics of this implementation? How well does it perform compared to the non-generic case?

  • PHP-MySQL: Arranging rows from seperate tables together/Expression to determine row origin

    - by Koroviev
    I'm new to PHP and have a two part question. I need to take rows from two separate tables, and arrange them in descending order by their date. The rows do not correspond in order or number and have no relationship with each other. ---EDIT--- They each contain updates on a site, one table holds text, links, dates, titles etc. from a blog. The other has titles, links, specifications, etc. from images. I want to arrange some basic information (title, date, small description) in an updates section on the main page of the site, and for it to be in order of date. Merging them into one table and modifying it to suit both types isn't what I'd like to do here, the blog table is Wordpress' standard wp_posts and I don't feel comfortable adding columns to make it suit the image table too. I'm afraid it could clash with upgrading later on and it seems like a clumsy solution (but that doesn't mean I'll object if people here advise me it's the best solution). ------EDIT 2------ Here are the DESCRIBES of each table: mysql> describe images; +---------+--------------+------+-----+-------------------+----------------+ | Field | Type | Null | Key | Default | Extra | +---------+--------------+------+-----+-------------------+----------------+ | id | int(11) | NO | PRI | NULL | auto_increment | | project | varchar(255) | NO | | NULL | | | title | varchar(255) | NO | | NULL | | | time | timestamp | NO | | CURRENT_TIMESTAMP | | | img_url | varchar(255) | NO | | NULL | | | alt_txt | varchar(255) | YES | | NULL | | | text | text | YES | | NULL | | | text_id | int(11) | YES | | NULL | | +---------+--------------+------+-----+-------------------+----------------+ mysql> DESCRIBE wp_posts; +-----------------------+---------------------+------+-----+---------------------+----------------+ | Field | Type | Null | Key | Default | Extra | +-----------------------+---------------------+------+-----+---------------------+----------------+ | ID | bigint(20) unsigned | NO | PRI | NULL | auto_increment | | post_author | bigint(20) unsigned | NO | | 0 | | | post_date | datetime | NO | | 0000-00-00 00:00:00 | | | post_date_gmt | datetime | NO | | 0000-00-00 00:00:00 | | | post_content | longtext | NO | | NULL | | | post_title | text | NO | | NULL | | | post_excerpt | text | NO | | NULL | | | post_status | varchar(20) | NO | | publish | | | comment_status | varchar(20) | NO | | open | | | ping_status | varchar(20) | NO | | open | | | post_password | varchar(20) | NO | | | | | post_name | varchar(200) | NO | MUL | | | | to_ping | text | NO | | NULL | | | pinged | text | NO | | NULL | | | post_modified | datetime | NO | | 0000-00-00 00:00:00 | | | post_modified_gmt | datetime | NO | | 0000-00-00 00:00:00 | | | post_content_filtered | text | NO | | NULL | | | post_parent | bigint(20) unsigned | NO | MUL | 0 | | | guid | varchar(255) | NO | | | | | menu_order | int(11) | NO | | 0 | | | post_type | varchar(20) | NO | MUL | post | | | post_mime_type | varchar(100) | NO | | | | | comment_count | bigint(20) | NO | | 0 | | +-----------------------+---------------------+------+-----+---------------------+----------------+ ---END EDIT--- I can do this easily with a single table like this (I include it here in case I'm using an over-elaborate method without knowing it): $content = mysql_query("SELECT post_title, post_text, post_date FROM posts ORDER BY post_date DESC"); while($row = mysql_fetch_array($content)) { echo $row['post_date'], $row['post_title'], $row['post_text']; } But how is it possible to call both tables into the same array to arrange them correctly? By correctly, I mean that they will intermix their echoed results based on their date. Maybe I'm looking at this from the wrong perspective, and calling them to a single array isn't the answer? Additionally, I need a way to form a conditional expression based on which table they came from, so that rows from table 1 get echoed differently than rows from table 2? I want results from table 1 to be echoed differently (with different strings concatenated around them, I mean) for the purpose of styling them differently than those from table two. And vice versa. I know an if...else statement would work here, but I have no idea how can I write the expression that would determine which table the row is from. All and any help is appreciated, thanks.

  • iPhone NSCalendar - Incorrect Calendar Drawn for users outside US

    - by xoail
    After trying to work on someone else's code, and so many different iterations, I am unable to understand what am I doing wrong with dates on a calendar month view. I am trying to present a calendar in month view fashion like calendar.app but unfortunately some users in countries like Australia, UK are reporting incorrect alignment of Days to Dates. For instance in Australia it displays 17th March as Friday. Any help is highly appreciated! Here is the code sample I am using: -(void)setCalendar { NSCalendar *gregorian = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; NSDateComponents *comps = [gregorian components:units fromDate:[NSDate date]]; self.currentDate = [gregorian dateFromComponents:comps]; NSInteger weekdayInteger=[comps weekday]; currentMonth=[comps month]; currentYear=[comps year]; NSString *dateString=[[NSString stringWithFormat:@"%@",currentDate] substringToIndex:10]; NSArray *array= [dateString componentsSeparatedByString:@"-"]; NSInteger currentDay=[[array objectAtIndex:2] intValue]; currentMonthConstant=currentMonth; currentYearConstant=currentYear; currentDayConstant=currentDay; currentConstantDate=[NSString stringWithFormat:@"%d/%d/%d",currentDayConstant,currentMonthConstant,currentYearConstant]; currentFirstDay=((8+weekdayInteger-(currentDay%7))%7); if(currentFirstDay==0) currentFirstDay=7; [gregorian release]; } And this is how im populating the calendar: -(void)fillCalender:(NSInteger)month weekStarts:(NSInteger)weekday year:(NSInteger)year { currentMonth=month; currentYear=year; currentFirstDay=weekday; UIButton *temp; NSInteger numberOfDays=[self getNumberofDays:month YearVlue:year]; currentLastDay=(currentFirstDay+numberOfDays-1)%7; if(currentLastDay==0) currentLastDay=7; NSString *monthName=[self getMonth:month]; NSInteger grid=(weekday-1); monthLabel.text=[NSString stringWithFormat:@"%@ %d",monthName,year]; for(int i=1;i<=numberOfDays;i++) { if([frontView isEqualToString:@"view1"]) temp=[arr_View2Buttons objectAtIndex:grid]; else temp= [arr_View1Buttons objectAtIndex:grid]; [temp setBackgroundImage:nil forState:UIControlStateNormal]; [temp setUserInteractionEnabled:TRUE]; UILabel *aLbl = (UILabel *)[temp viewWithTag:123]; [aLbl setText:[NSString stringWithFormat:@"%d",i]]; // check for today if(currentDayConstant == i && currentMonthConstant == currentMonth && currentYearConstant == currentYear) { [aLbl setTextColor:[UIColor blueColor]]; } else { [aLbl setTextColor:[UIColor colorWithRed:69/255.0 green:2/255.0 blue:71/255.0 alpha:1.0]]; } [temp setTag:i]; grid++; if(grid==35) grid=0; } } And finally viewdidload: - (void)viewDidLoad { [super viewDidLoad]; [self setCalendar]; // set views [self.view1 setFrame:CGRectMake(0,45,320,232)]; [self.view2 setFrame:CGRectMake(0,277,320,232)]; [self.view addSubview:self.view1]; [self.view addSubview:self.view2]; frontView = @"view2"; [self fillCalender:currentMonth weekStarts:currentFirstDay year:currentYear]; frontView = @"view1"; }

  • What's the best way of accessing a DRb object (e.g. Ruby Queue) from Scala (and Java)?

    - by Tom Morris
    I have built a variety of little scripts using Ruby's very simple Queue class, and share the Queue between Ruby and JRuby processes using DRb. It would be nice to be able to access these from Scala (and maybe Java) using JRuby. I've put together something Scala and the JSR-223 interface to access jruby-complete.jar. import javax.script._ class DRbQueue(host: String, port: Int) { private var engine = DRbQueue.factory.getEngineByName("jruby") private var invoker = engine.asInstanceOf[Invocable] engine.eval("require \"drb\" ") private var queue = engine.eval("DRbObject.new(nil, \"druby://" + host + ":" + port.toString + "\")") def isEmpty(): Boolean = invoker.invokeMethod(this.queue, "empty?").asInstanceOf[Boolean] def size(): Long = invoker.invokeMethod(this.queue, "length").asInstanceOf[Long] def threadsWaiting: Long = invoker.invokeMethod(this.queue, "num_waiting").asInstanceOf[Long] def offer(obj: Any) = invoker.invokeMethod(this.queue, "push", obj.asInstanceOf[java.lang.Object]) def poll(): Any = invoker.invokeMethod(this.queue, "pop") def clear(): Unit = { invoker.invokeMethod(this.queue, "clear") } } object DRbQueue { var factory = new ScriptEngineManager() } (It conforms roughly to java.util.Queue interface, but I haven't declared the interface because it doesn't implement the element and peek methods because the Ruby class doesn't offer them.) The problem with this is the type conversion. JRuby is fine with Scala's Strings - because they are Java strings. But if I give it a Scala Int or Long, or one of the other Scala types (List, Set, RichString, Array, Symbol) or some other custom type. This seems unnecessarily hacky: surely there has got to be a better way of doing RMI/DRb interop without having to use JSR-223 API. I could either make it so that the offer method serializes the object to, say, a JSON string and takes a structural type of only objects that have a toJson method. I could then write a Ruby wrapper class (or just monkeypatch Queue) to would parse the JSON. Is there any point in carrying on with trying to access DRb from Java/Scala? Might it just be easier to install a real message queue? (If so, any suggestions for a lightweight JVM-based MQ?)

  • Can C++ do something like an ML case expression?

    - by Nathan Andrew Mullenax
    So, I've run into this sort of thing a few times in C++ where I'd really like to write something like case (a,b,c,d) of (true, true, _, _ ) => expr | (false, true, _, false) => expr | ... But in C++, I invariably end up with something like this: bool c11 = color1.count(e.first)>0; bool c21 = color2.count(e.first)>0; bool c12 = color1.count(e.second)>0; bool c22 = color2.count(e.second)>0; // no vertex in this edge is colored // requeue if( !(c11||c21||c12||c22) ) { edges.push(e); } // endpoints already same color // failure condition else if( (c11&&c12)||(c21&&c22) ) { results.push_back("NOT BICOLORABLE."); return true; } // nothing to do: nodes are already // colored and different from one another else if( (c11&&c22)||(c21&&c12) ) { } // first is c1, second is not set else if( c11 && !(c12||c22) ) { color2.insert( e.second ); } // first is c2, second is not set else if( c21 && !(c12||c22) ) { color1.insert( e.second ); } // first is not set, second is c1 else if( !(c11||c21) && c12 ) { color2.insert( e.first ); } // first is not set, second is c2 else if( !(c11||c21) && c22 ) { color1.insert( e.first ); } else { std::cout << "Something went wrong.\n"; } I'm wondering if there's any way to clean all of those if's and else's up, as it seems especially error prone. It would be even better if it were possible to get the compiler complain like SML does when a case expression (or statement in C++) isn't exhaustive. I realize this question is a bit vague. Maybe, in sum, how would one represent an exhaustive truth table with an arbitrary number of variables in C++ succinctly? Thanks in advance.

  • Titanium TableViewRow classname with custom rows

    - by pancake
    I would like to know in what way the 'className' property of a Ti.UI.TableViewRow helps when creating custom rows. For example, I populate a tableview with custom rows in the following way: function populateTableView(tableView, data) { var rows = []; var row; var title, image; var i; for (i = 0; i < data.length; i++) { title = Ti.UI.createLabel({ text : data[i].title, width : 100, height: 30, top: 5, left: 25 }); image = Ti.UI.createImage({ image : 'some_image.png', width: 30, height: 30, top: 5, left: 5 }); /* and, like, 5+ more views or whatever */ row = Ti.UI.createTableViewRow(); row.add(titleLabel); row.add(image); rows.push(row); } tableView.setData(rows); } Of course, this example of a "custom" row is easily created using the standard title and image properties of the TableViewRow, but that isn't the point. How is the allocation of new labels, image views and other child views of a table view prevented in favour of their reuse? I know in iOS this is achieved by using the method -[UITableView dequeueReusableCellWithIdentifier:] to fetch a row object from a 'reservoir' (so 'className' is 'identifier' here) that isn't currently being used for displaying data, but already has the needed child views laid out correctly in it, thus only requiring to update the data contained within (text, image data, etc). As this system is so unbelievably simple, I have a lot of trouble believing the method employed by the Titanium API does not support this. After reading through the API and searching the web, I do however suspect this is the case. The 'className' property is recommended as an easy way to make table views more efficient in Titanium, but its relation to custom table view rows is not explained in any way. If anyone could clarify this matter for me, I would be very grateful.

  • PHP - Nested Looping Trouble

    - by Jeremy A
    I have an HTML table that I need to populate with the values grabbed from a select statement. The table cols are populated by an array (0,1,2,3). Each of the results from the query will contain a row 'GATE' with a value of (0-3), but there will not be any predictability to those results.

  • how do I get a new line, after using float:left?

    - by codeman73
    What I am trying to do is have rows of images, 6 images in each row. Some of these images need to have another image floating on top of them (flush with the lower-right corner). I was able to get that to work from this thread: http://stackoverflow.com/questions/48474/how-do-i-position-one-image-on-top-of-another-in-html However, now I'm unable to get the new row after the 6th image. Neither <BR> or <P> create a new line. They simply push the next image down several pixels, but the image is still in the same line. It seems like the float style is interfering with the <BR> and/or <P>. I tried using different styles for the image that starts a new row, like float:none and display:block, but neither worked. The odd thing is that the new line starts after the 7th image. Here's what I'm using so far: <style type="text/css"> .containerdiv { float: left; position: relative; } .containerdivNewLine { float: none; display: block; position: relative; } .cornerimage { position: absolute; bottom: 0; right: 0; } </style> <div class="containerdiv"> <img border="0" height="188" src="myImg" width="133" /> <img class="cornerimage" height="140" src="imageOnTop" width="105" /> </div> For the 7th image, when I'm trying to start a new row, I'm simply replacing the 'containerdiv' class with 'containerdivNewLine'.

  • Google Maps API v3 - infoWindows all have same content

    - by paulriedel
    Hello, I've been having problems with the infoWindows and Google Maps API v3. Initially, I've ran into the problem that everyone else has of closing infoWindows when opening a new one. I thought to have solved the problem by defining "infowindow" beforehand. Now they close when I click on a new marker, but the content is the same. How should I re-structure my code to make sure the content is the right one each time - and only one infoWindow is open at a given time? Thank you! Paul var allLatLngs = new Array(); var last = 0; var infowindow; function displayResults(start, count){ if(start === undefined){ start = last; } if(count === undefined){ count = 20; } jQuery.each(jsresults, function(index, value) { if(index >= start && index < start+count){ var obj = jQuery.parseJSON(value); $("#textresults").append(index + ": <strong>" + obj.name + "</strong> " + Math.round(obj.distanz*100)/100 + " km entfernt" + "<br/>"); var myLatlng = new google.maps.LatLng(obj.geo_lat, obj.geo_lon); allLatLngs.push(myLatlng); var contentString = '<strong>'+obj.name+'</strong>'; infowindow = new google.maps.InfoWindow({ content: contentString }); var marker = new google.maps.Marker({ position: myLatlng, //title:"Hello World!" }); marker.setMap(map); google.maps.event.addListener(marker, 'click', function() { if (infowindow) { infowindow.close(map,marker); } infowindow.open(map,marker); }); } }); last = start+count;

  • UINavigationController not working under ARC in iPhone

    - by user1811427
    I have creared a new project "Empty Application" template in Xcode 4.3, it is having only two classes AppDelegate.h & .m I cheaked with ARC to use automatic reference count while creating the app. I added two new files "RootViewController" & "NewProjectViewControllers". I implemented code to set navigation controller as follows in AppDelegate - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; // Override point for customization after application launch. rootViewController = [[MainViewController alloc] init]; UINavigationController *navigation = [[UINavigationController alloc] initWithRootViewController:rootViewController]; [self.window addSubview:navigation.view]; self.window.backgroundColor = [UIColor whiteColor]; [self.window makeKeyAndVisible]; return YES; } and in hte home view (Root view controller) implemented as follows - (void)viewDidLoad { [super viewDidLoad]; self.title = @"Projects"; UINavigationBar *navigationBar = [self.navigationController navigationBar]; [navigationBar setTintColor: [UIColor colorWithRed:10/255.0f green:21/255.0f blue:51/255.0f alpha:1.0f]]; //To set the customised bar item UIButton *rightBarBtn = [UIButton buttonWithType:UIButtonTypeCustom]; [rightBarBtn setBackgroundImage:[UIImage imageNamed:@"plus_new.png"] forState:UIControlStateNormal]; rightBarBtn.frame=CGRectMake(0.0, 100.0, 30.0, 30.0); [rightBarBtn addTarget:self action:@selector(addProject) forControlEvents:UIControlEventTouchUpInside]; UIBarButtonItem* rightBarItem = [[UIBarButtonItem alloc] initWithCustomView:rightBarBtn]; self.navigationItem.rightBarButtonItem = rightBarItem; // Do any additional setup after loading the view from its nib. } - (void) addProject { NewProjViewController *editProject = [[NewProjViewController alloc] init]; [self.navigationController pushViewController:editProject animated:YES]; NSLog(@"xxxxxxxxxxxxxxx"); } But since i used ARC the navigation may dealoc immediately and it doesn't work, All the actions in method works except push to the next view if i do same thing with out ARC it works fine How to resolve this issue..? Thanks in advance

  • App is fast on 3GS but slow on 3G

    - by Anthony Chan
    Hi all, I'm new to computer coding and have just finished coding an app and tested it on both 3G and 3GS. On 3GS, it worked as normal as on the simulator. However, when I tried to run it on 3G, the app becomes extremely slow. I'm not sure what's the reason and I hope someone could shed some light on me. Generally, my app has a couple of view controller classes, with one of them being the title page, one being the main page, one is setting, etc. I used a dissolve to transition from the title page to the main page. But even this simple transition shows un-smooth performance on a 3G! My other part of the app involves zooming in to some images by scaling up the images, switching images by push or dissolve upon receiving touch events, saving photos into photo library and storing and retrieving some photos in a folder and some data in a SQlite database, each showing un-smooth actions. Compared with some heavy graphic or heavy maths app, I think mine is pretty simple. I totally have no clue why the app would behave so slow and un-smooth that it is barely useful on a 3G. Any help/ direction would be much appreciated. Thanks for helping out.

  • Need help with regex parsing (in perl)

    - by Charlie
    Hi all, need some help parsing an html file in perl. I used the LWP module to retrieve a webpage into $_ with $/ undefined so there are no newline issues. Then I'm trying to find all strings matching a pattern. How do I do that? I know how to find 1 instance of it, but how do I match all instances? and what data structure would the results go to? a multi dimensional array? my text (excerpt) looks like the following: <TR> <TD BGCOLOR=EEEEEE><A HREF="/program.cgi?pid=1233"><FONT FACE="ARIAL,HELVETICA,SANS-SERIF" SIZE=2>Title 1</A></FONT></TD> <TD BGCOLOR=EEEEEE nowrap><FONT FACE="ARIAL,HELVETICA" SIZE=2>Jun 27 2010 3:00PM</FONT></TD> <TD BGCOLOR=EEEEEE>&nbsp;</TD> </TR> <TR><TD BGCOLOR=EEEEEE COLSPAN=3><IMG SRC="http://images.domain.com/images/spacer.gif" WIDTH=1 HEIGHT=2><BR></TD></TR> <TR><TD COLSPAN=3 BGCOLOR=999999><IMG SRC="http://images.domain.com/images/spacer.gif" HEIGHT=1 WIDTH=1></TD></TR> <TR><TD COLSPAN=3 ><IMG SRC="http://images.domain.com/images/spacer.gif" WIDTH=1 HEIGHT=2><BR></TD></TR> <TR> <TD><A HREF="/program.cgi?pid=1234"><FONT FACE="ARIAL,HELVETICA,SANS-SERIF" SIZE=2>Title 2</A></FONT></TD> <TD nowrap><FONT FACE="ARIAL,HELVETICA" SIZE=2>Jun 29 2010 7:00PM</FONT></TD> <TD>&nbsp;</TD> </TR> <TR><TD COLSPAN=3><IMG SRC="http://images.domain.com/images/spacer.gif" WIDTH=1 HEIGHT=2><BR></TD></TR> <TR><TD COLSPAN=3 BGCOLOR=999999><IMG SRC="http://images.domain.com/images/spacer.gif" HEIGHT=1 WIDTH=1></TD></TR> <TR><TD COLSPAN=3 BGCOLOR=EEEEEE><IMG SRC="http://images.domain.com/images/spacer.gif" WIDTH=1 HEIGHT=2><BR></TD></TR> <TR> <TD BGCOLOR=EEEEEE><A HREF="/program.cgi?pid=1235"><FONT FACE="ARIAL,HELVETICA,SANS-SERIF" SIZE=2>Title 3</A></FONT></TD> <TD BGCOLOR=EEEEEE nowrap><FONT FACE="ARIAL,HELVETICA" SIZE=2>Jul 3 2010 7:00PM</FONT></TD> <TD BGCOLOR=EEEEEE>&nbsp;</TD> </TR> I want to get the following into an array (or any structure): { ["/program.cgi?pdi=1233", "Title 1"], ["/program.cgi?pdi=1234", "Title 2"], ["/program.cgi?pdi=1235", "Title 3"] } Thanks

  • wordpress php > div issue

    - by Philip Bateman
    Thanks in advance for you help Ive been doing this as a lovejob for friends and now im getting quotes of several hundred dollars for minor homepage variation and I'm not sure if its valid. I'm not a programmer myself, just trying hard :) Via the CafePress press75 theme, I'm trying to go from 1 / 2 / 3 column home layout, to 1-2 merged and 3, push the 2nd column data to the right and have the 1st column span as a 16:9 gallery (nextgengallery plugin installed). Is this really a complex thing from a coding perspective? The current guy talking to me is saying its going to cost $700 or 800 AUD to alter, which is rough when the template cost $85.. From this http://shocolate.com.au.previewdns.com/wp-content/uploads/2010/05/shocolatecurrent.jpg to this 'url+Shocolatelooklikethis.jpg' I was able to get the sidebar removed by taking out ‘‘ near the bottom of home.css.. Just can’t get the middle data to flow over it? This would be ideal as a result, as the system puts the latest selected blog post on the homepage, so if we can get rid of the sidebar div and have the text appear where it was, that would be ideal. Removing the sidebar from the bottom of home.php and setting the thumbnail width to say 450 gives me the result im after EXCEPT the text doesn’t fill where the sidebar is, it wraps underneath. Reference 'shocolate.com.au.previewdns.com' for current site Thank you!!! Phil (Melbourne)

  • Javascript Closures, Callbacks, This and That

    - by nazbot
    I am having some trouble getting a callback function to work. Here is my code: SomeObject.prototype.refreshData = function() { var read_obj = new SomeAjaxCall("read_some_data", { }, this.readSuccess, this.readFail); } SomeObject.prototype.readSuccess = function(response) { this.data = response; this.someList = []; for (var i = 0; i < this.data.length; i++) { var systemData = this.data[i]; var system = new SomeSystem(systemData); this.someList.push(system); } this.refreshList(); } Basically SomeAjaxCall is making an ajax request for data. If it works we use the callback 'this.readSuccess' and if it fails 'this.readFail'. I have figured out that 'this' in the SomeObject.readSuccess is the global this (aka the window object) because my callbacks are being called as functions and not member methods. My understanding is that I need to use closures to keep the 'this' around, however, I have not been able to get this to work. If someone is able show me what I should be doing I would appreciate it greatly. I am still wrapping my head around how closures work and specifically how they would work in this situation. Thanks!

  • Fastest way to read data from a lot of ASCII files

    - by Alsenes
    Hi guys, for a college exercise that I've already submitted I needed to read a .txt file wich contained a lot of names of images(1 in each line). Then I needed to open each image as an ascii file, and read their data(images where in ppm format), and do a series of things with them. The things is, I noticed my program was taking 70% of the time in the reading the data from the file part, instead of in the other calculations that I was doing (finding number of repetitions of each pixel with a hash table, finding diferents pixels beetween 2 images etc..), which I found quite odd to say the least. This is how the ppm format looks like: P3 //This value can be ignored when reading the file, because all image will be correctly formatted 4 4 255 //This value can be also ignored, will be always 255. 0 0 0 0 0 0 0 0 0 15 0 15 0 0 0 0 15 7 0 0 0 0 0 0 0 0 0 0 0 0 0 15 7 0 0 0 15 0 15 0 0 0 0 0 0 0 0 0 This is how I was reading the data from the files: ifstream fdatos; fdatos.open(argv[1]); //Open file with the name of all the images const int size = 128; char file[size]; //Where I'll get the image name Image *img; while (fdatos >> file) { //While there's still images anmes left, continue ifstream fimagen; fimagen.open(file); //Open image file img = new Image(fimagen); //Create new image object with it's data file ……… //Rest of the calculations whith that image ……… delete img; //Delete image object after done fimagen.close(); //Close image file after done } fdatos.close(); And inside the image object read the data like this: const int tallafirma = 100; char firma[tallafirma]; fich_in >> std::setw(100) >> firma; // Read the P3 part, can be ignored int maxvalue, numpixels; fich_in >> height >> width >> maxvalue; // Read the next three values numpixels = height*width; datos = new Pixel[numpixels]; int r,g,b; //Don't need to be ints, max value is 256, so an unsigned char would be ok. for (int i=0; i<numpixels; i++) { fich_in >> r >> g >> b; datos[i] = Pixel( r, g ,b); } //This last part is the slow one, //I thing I should be able to read all this data in one single read //to buffer or something which would be stored in an array of unsigned chars, //and then I'd only need to to do: //buffer[0] -> //Pixel 1 - Red data //buffer[1] -> //Pixel 1 - Green data //buffer[2] -> //Pixel 1 - Blue data So, any Ideas? I think I can improve it quite a bit reading all to an array in one single call, I just don't know how that is done. Also, is it posible to know how many images will be in the "index file"? Is it posiible to know the number of lines a file has?(because there's one file name per line..) Thanks!!
