• Zend Framework headLink() helper and HTML5

  - by Richard Knop

  I have set doctype to HTML 5 like this: $view->doctype('HTML5'); Then I have added a stylesheet like this: $view->headLink()->appendStylesheet($view->baseUrl().'/css/reset.css'); It produces link tag like this: <link href="/css/reset.css" media="screen" rel="stylesheet" type="text/css" > But for HTML 5 this would be correct, no? <link rel="stylesheet" href="/css/reset.css"> One more question. How to produce meta tag like this with headMeta() helper? <meta charset="utf-8">

• DIV appear differently in chrome only.

  - by DreamWave

  I have a website at bgflirt.com that appears differently in FireFox and Chrome. This is how it looks in firefox: and here's how it looks in chrome: As you can see, in chrome (and safari) the page is not stretched to fit the entire screen. I'm using this code for positioning the div containing the flash on the right: <div style="width: 200px; position: absolute; right: 0px; top: 10px; overflow: hidden;"> </div> The page should look the way it does in firefox, in all browsers. Any ideas on how to fix this will be greatly appreciated !

• ViewDidLoad not being called with my custom UIViewController

  - by user1060500

  I have created a custom UIViewController class that creates a ScrollView at runtime that it loads into the view. See code here in the constructor of my custom UIViewController. initControl(id, canEdit); _controllers = new NSMutableArray(0); //required to keep view controllers around _scrollView = new UIScrollView(); _scrollView.BackgroundColor = UIColor.Green; this.View = _scrollView; ViewDidAppear and ViewWillAppear are called normally. ViewDidLoad is not called which I am not sure why as the view is showing up on the screen just fine. Any ideas?

• Where can I find a compact programming keyboard with logical key placement?

  - by Lefler

  I recently, at the order of my chiropractor, bought a laptop stand to elevate my screen. A result of this is that I need a standalone keyboard. Normal keyboards have numeric keypads on the right side, which moves my mouse further to the right... not an optimal position chiropractically speaking. I don't use the numeric keypad, but all the compact keyboards I can find use some random placement algorithm on the arrow, page up/down, and most importantly -- the insert,delete,home and end keys. Those misplaced keys are crippling my code entry. Does anyone know of a keyboard that is minus the keypad, but places those VERY IMPORTANT keys in a more standard position?

• Calculating toolbar icon width

  - by TheWzrdOz

  I am building an RDP client and I have toolbar that shows the running applications, same as the Windows toolbar. I need to support dual monitors, so my questions are 1) How do I detect that there is more than one monitor and 2) Is there a formula for calculating the width of the icons on the toolbar? I know that at the start, the width is not dependent on the number of monitors, and is always the same size. What does change is the number of icons I can display before I must start "shrinking" their width, and it will depend on the screen resolution as well. Any ideas?

• Javascript for removing menu and scroll bars

  - by nWight

  Hi - I have this script on my html page: parent.resizeTo(550,510); I'd like to add to it so it positions the window in the middle of the screen. Also, I want to remove the address and tool bars (I've managed to hide the scrollbars by using body{overflow:hidden;}). I know how to do this using JS upon opening a new window from the browser but this needs to work from clicking a link on a PDF. Does anyone have any suggestions? Thank you!

• Is it possible to align an element with the bottom of the window, yet make it scrollable, with CSS o

  - by last-child

  I have a design going on where I want to align the bottom of an intro paragraph with the bottom of the window, yet make it scroll with the rest of the page. So when the page opens, the visitor sees only the first paragraph (and a full screen background image, which is what I want to focus their attention on), but as they scroll they see the paragraph and the rest of the text. The height of the intro element can vary. Right now I think I have to introduce some javascript to do this - meassure the height of the window, the height of the paragraph, and adjust top: or margin-top of the paragraph to the difference between the two values. If there is a way to make a div have a height that corresponds exactly to the window height, and position the paragraph absolutely inside of this div, the let the rest of the text sit outside of the div, it could work... but I can't seem to make that happen with css. Any suggestions?

• Graphics Question: How do I restrict the mouse cursor to within a circle?

  - by Dan

  I'm playing with XNA. When I click the left mouse button, I record the X,Y co-ordinates. Keeping the mouse button held down, moving the mouse draws a line from this origin to the current mouse position. I've offset this into the middle of the window. Now, what I'd like to do is restrict the mouse cursor to within a circle (with a radius of N, centred on the middle of the screen). Restricting the mouse to a rectangular region is easy enough (by adjusting the origin by the difference of the mouse position and the size of the region), but I haven't a clue on how to start doing it for a circular region. Can anyone explain how to do this? Any advice on where to start would be helpful.

• How do I escape a new line character in a .ini file so that Zend_Config_Ini reads it literally?

  - by Nick

  I am trying to store a multiple line e-mail in an ini file using PHP/Zend Framework. My string has new lines characters in it, and when I use Zend_Config_Ini to parse the ini file, the new line characters come back escaped, so they are printed out on screen, instead of a line feed. Example: // ini file message = Hi {0},\n\nThis is a test message.\nGoodbye! is parsed by Zend_Config_Ini as: Hi {0},\\n\\nThis is a test message.\\nGoodbye! which then is printed out in the email as: Hi John,\n\nThis is a test message.\nGoodbye! Instead I want the e-mail to look like this: Hi John, This is a test message. Goodbye! Does anybody know how to achieve this? Thanks!

• Adding a border (Fixed3D) to an existing borderless application

  - by Aphelion

  Hi there, I have an .NET application that always starts itself with its border style to 'None', as it is supposed to be an full-screen application with a fixed resolution. However, i would like to add the window border (Fixed3D) to this window when the application starts so that I am able to move it around my desktop. My first idea was to have a tray app running, monitoring event messages, and somehow change the window style when this specific application starts. However, I am not sure if this will work and how to do this. Anyone that can point me in the right direction?

• Recursive MySQL function call eats up too much memory and dies.

  - by kylex

  I have the following recursive function which works... up until a point. Then the script asks for more memory once the queries exceed about 100, and when I add more memory, the script typically just dies (I end up with a white screen on my browser). public function returnPArray($parent=0,$depth=0,$orderBy = 'showOrder ASC'){ $query = mysql_query("SELECT *, UNIX_TIMESTAMP(lastDate) AS whenTime FROM these_pages WHERE parent = '".$parent."' AND deleted = 'N' ORDER BY ".$orderBy.""); $rows = mysql_num_rows($query); while($row = mysql_fetch_assoc($query)){ // This uses my class and places the content in an array. MyClass::$_navArray[] = array( 'id' => $row['id'], 'parent' => $row['parent'] ); MyClass::returnPArray($row['id'],($depth+1)); } $i++; } Can anyone help me make this query less resource intensive?

• ActionScript - One Button Limit (Exclusive Touch) For Mobile Devices?

  - by TheDarkIn1978

  two years ago, when i was developing an application for the iPhone, i used the following built-in system method on all of my buttons: [button setExclusiveTouch:YES]; essentially, if you had many buttons on screen, this method insured that the application wouldn't be permitted do crazy things when several button events firing at the same time. problematic: ButtonA and ButtonB are available. each button has a mouse up event which fire a specific reorganization/layout of the UI. if both button's events are fired at the same time, their events will likely conflict, causing a strange new layout, perhaps a runtime error. solution: application buttons cancel any current pending mouse up events when said button enters mouse down. private function mouseDownEventHandler(evt:MouseEvent):void { //if other buttons are currently in a mouse down state ready to fire //a mouse up event, cancel them all here. } of course it's simple to manually handle this if there are only a few buttons on stage, but managing buttons becomes more and more complicated / bug-prone if there are several / many buttons available. is there a convenience method available in AIR specifically for this functionality?

• How to automatically reflect the new Updates (on Database) to User Pages

  - by user296436

  I am trying to create a new Notice Alert using PHP and Javascript. Suppose that a 100 users are currently logged into to the Online Notice Board Application and any One user posts a new notice. I want an immediate alert signal on all the users screen. I know, that the simplest way of doing it is to constantly Ping the server but I don't want to do it as it will slow down the server. Moreover, I am on a shared host. So I don't have access to any Socket Port. That means, I cannot establish any direct Socket Communication Channel from the Server to the User Machine. Can any one suggest me some other solution to this kind of problems???

• What can you do in ::OnInitDialog() Visual Studio 2008 C++

  - by flirishman

  What can or cannot you do in ::OnInitDialog() Visual Studio 2008 C++ I would like to write out some text on the dialog at the dialog startup. If I put the same code in a PUSH-BUTTON OnBnClicked it works. If I put it in the OnInit, it does not give me the text on the screen. I'm assuming at the OnInit, my dialog box is not completely up, so I cannot write on it? CRect drawRect; drawRect.left = 00; // Shifts text to right drawRect.right = 300; drawRect.top = 00; // How Far Down drawRect.bottom = 300; // Clear out any previous name CString strBlank = "Book Name"; SSTextOut(this->GetDC(), strBlank, &drawRect, DT_LEFT); The function I am writing to is described in http://www.codeproject.com/KB/GDI/SSTextOut.aspx

• How long would this have to go on for...

  - by Pieman

  I have the Pi formulae -Well one of them... 1 - 1/3 + 1/5 - 1/7 etc. How long would it take to get to like 1000 S.F correct? -Well, not how long, how big would the denominator be? -I have it updating 4 times in one refresh: http://zombiewrath.com/pi.php So the section above would be done in one refresh, then 7 to 13 in another etc. Answer this maths question please :) Also how can I get the 10,002 length variable onto 'seperate lines'? -I want it to fill 100% screen width -no scrolling needed (well downwards only)

• Rails: updating an item along with associated items

  - by shmichael

  Suppose I have a simple to-do list application. The application contains two models: lists (have an owner and description) items (have name and due-date) that belong to a specific list I would like to have a single edit screen for a list in which I update the list attributes (such as description) and also create/delete/modify associated items. There should be a single "save" button that will commit all changes. Unless save is pressed, any change to the list and the items should be forgotten. I wasn't able to find an elegant best practice for this. Would greatly appreciate any suggestions and/or references to existing implementations.

• .Htaccess & Wildcard Subdomains — Can't get other variables to work!

  - by Justin Scheetz

  It would be absolutely awesome if someone could help me out here. I have a domain, let's call it "example.com". I have wildcard subdomains setup and working great. The only problem is I can't get htaccess to see anything else like subdomain.example.com/profile/some_name/some_id_number/. In fact, I can type any garbage after the domain and it will still just show me the home screen. Here's what's in my htaccess file now: Options +FollowSymLinks Options +Indexes Options -Multiviews RewriteEngine On RewriteCond %{REQUEST_URI} !^/app/index.php RewriteCond %{HTTP_HOST} !^www\.example\.com RewriteCond %{HTTP_HOST} ^([^.]+)\.example\.com RewriteRule (.*) /app/index.php?user%1 [L] I can see why that wouldn't work yet, but I wanted to add something similar to the following: RewriteRule ^profile/([^/]+)/([^/]+) /app/index.php?page=profile&username=$1&user_id=$2 [nc] But it's not working at all. The server doesn't even really show signs that it's even seeing it there. Any ideas?

• Extending folder (LiveFolder?) class

  - by yamsha

  So, I noticed that I can organize apps into folders (HTC Incredible). However these folders are fairly limited in their capabilities. I want to implement an activity that extends the "base" folder activity (at the very least I want to add the ability to rearrange items in folders), but I can't figure out the class name... So, what's the name of the class that is used when adding a "New Folder" to the Home screen? PS I did take a look at the Android developer website. But the discussion there revolves mostly around content providers. I assume that's not quite what I need since I'd have to create a separate content provider for each new folder, or am I misunderstanding something?

• Adding the scrollview created by photoscroller to a subview

  - by wierddemon

  I'm trying to modify Apple's PhotoScroller example to make the scrollview that is created into a subview instead of it being a view that takes up the entire screen. Any ideas on how this can be accomplished? - (void)loadView { // Step 1: make the outer paging scroll view CGRect pagingScrollViewFrame = [self frameForPagingScrollView]; pagingScrollView = [[UIScrollView alloc] initWithFrame:pagingScrollViewFrame]; pagingScrollView.pagingEnabled = YES; pagingScrollView.backgroundColor = [UIColor blackColor]; pagingScrollView.showsVerticalScrollIndicator = NO; pagingScrollView.showsHorizontalScrollIndicator = NO; pagingScrollView.contentSize = [self contentSizeForPagingScrollView]; pagingScrollView.delegate = self; // When I do this it fails [self.view addSubview:pagingScrollView]; // Step 2: prepare to tile content recycledPages = [[NSMutableSet alloc] init]; visiblePages = [[NSMutableSet alloc] init]; [self tilePages]; }

• Is it faster to count down that it is to count up?

  - by Bob

  Our computer science teacher once said that for some reason it is more efficient to count down that count up. For example if you need to use a FOR loop and the loop index is not used somewhere (like printing a line of N * to the screen) I mean that code like this : for (i=N; i>=0; i--) putchar('*'); is better than: for (i=0; i<N; i++) putchar('*'); Is it really true? and if so does anyone know why?

• Sidescrolling UI on iPhone

  - by Michael

  Please lead me in the right direction. I need to provide user with small text centered on the iPhone screen. User can make quick scroll left or right in order to get the next or previous text. There can be hundreds of such text pieces. The process itself is similar to Photo application sidescrolling but much simple, no zoom. As far as I can understand I need to use UIScrollView class, then call hundreds of addSubviews? Is it the optimal way or I should always keep 3 subviews and replace them on the fly? What kind of tricks should be used to achieve the "scroll and center" effect? Thanks

• UIAlertView popups lock up keyboard actions

  - by TurbZ

  I have a strange behavior where if a UIAlert fires (like the one below) all subsequent keyboard or press behaviors are disabled / non responsive. Scrolling the screen still works but no action is fired from any button or keyboard presses. [[[[UIAlertView alloc] initWithTitle:@"Invalid Address" message:@"The email address you entered isn't valid. Please check and try again." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil] autorelease] show]; Anyone experienced this behavior before and can shed some light? Or maybe guide me in the right direction to debug it further to get to the root cause? Thank you heaps!
