  • Reduce white space between lines of text

    - by user654466
    I am creating a webpage (first time) and i'm following as much of the CSS rules and tags as I can. However, I ran into a problem with white space. I've underlined the first line of text but now the second line seems to have drifted below. Is there a way to make it a bit more snug, i'd like the second line of text to be just below the above line. body,td,th { color: #000000; } body { margin: 0; padding: 0; padding-top: 6px; text-align: center; background-color: #FFFFFF; } #centered { width: 800px; /* set to desired width in px or percent */ text-align: left; /* optionally you could use "justified" */ border: 0px; /* Changing this value will add lines around the centered area */ padding: 0; margin: 0 auto; } .style3 { font-size: 32pt; color: #666666; margin-left: 0px; border-bottom: 3px double; } .style5 { margin-left: 390px; font-size: 32pt; color: #CCCCCC; } --> </style></head> <div id="centered"> <body> <p class="style3">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;FIRST LINE OF TEXT</p> <p class="style5">INDENTED SECOND LINE</p> </body> </div> </body> </html>

  • How to move from custom to transluscent NavigationBar and back? Display problems!

    - by jd291
    So, i got this Navigation-based App (with a custom NavigationBar - Category) and I have 2 problems here... @implementation UINavigationBar (Custom) - (void)drawRect:(CGRect)rect { UIImage *image = [UIImage imageNamed: @"bg_toolbar.png"]; [image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)]; } @end Because of the Navigation-based App, most of the views have a height of 436px (= ScreenSize - NavigationBar height, as you probably know ;). I got one view similar to the photo app overview showing all the thumbnails, from there I push a viewcontroller containing the scroll view (like in photos app) on the stack, like so - (void)buttonPressed:(id)sender { UIButton *btn = (UIButton *)sender; PhotoSetScrollViewController *psc = [[PhotoSetScrollViewController alloc] initWithPhotoArray:photos andID:btn.tag]; [self.navigationController pushViewController:psc animated:YES]; } Problem 1: The view holding the fullscreen scrollview has a height of 480px which seems to be a problem because when poping the viewcontroller by hitting the back button, the view containing the thumbnails (height 436px) moves upward below the navigation bar. And also the Toolbar keeps showing. What could be the problem? Problem 2: How could I switch between my custom navigation bar and the standard black translucent style?

  • Linux Mint on VirtualBox has no internet connection

    - by Martin
    Physical machine: Mac Mini running OSX 10.7.5 Virtual machine: Linux Mint 15 Cinnamon 64-bit Using VirtualBox. I am trying to make the linux connect to the internet. For some reason I can access the host computer with 192.168.2.100. Its set up to show me a web-page that says "It works". This I can see from the linux. But I cannot reach anything on the internet. Either FireFox says "Unable to connect" or when I run nslookup google.com I get connection timed out; no servers could be reached. My setting on VirtualBox under the Network tab are: Bridge Adapter vnic0 promiscouos Mode:Allow All`. If it makes a difference, the host has a WiFi connection to the home router. What have I missed?

  • How to columnate text with tabs (in vim or on the shell)

    - by kine
    I have a frequent need to manually manipulate tab-delimited text for data entry and other purposes, and when i do this it helps if the text is aligned properly into columns. For example (assuming 4-space tabs): # original format abcdefghijklmnop field2 abcdefgh field2 abcdefghijkl field2 # ideal format abcdefghijklmnop field2 abcdefgh field2 abcdefghijkl field2 I am very familiar with using the column utility to columnate text this way, but the problem is that it uses spaces to align the columns, and i specifically need tabs. This requirement also appears to rule out the Tabularize plug-in. Is there any way that i can columnate text with tabs specifically, either within vim or at the shell? It looks like i might be able to do it with groff/tbl, but honestly i'd rather columnate it by hand than mess with that....

  • Why is Chrome miscalculating jQuery submenu dimensions?

    - by chunkymonkey
    I'm trying to implement this dropdown menu with flyouts: http://jsfiddle.net/chunkymonkey/fr6x4/ In Chrome certain categories can be expanded to show their subcategories while others show nothing when opened up. For example: Alternative Rock can be expanded to show its multiple subcategories . . . BUT . . . World Music, which has as many subcategories, shows no subcategories when expanded. (SCREENSHOT: http://i.imgur.com/0WorR.jpg) I thought I had tracked this problem down to a problem with they way the dimensions of the dropdown elements are calculated in the original code: First change: - var newLeftVal = - ($('.fg-menu-current').parents('ul').size() - 1) * 180; + var newLeftVal = - ($('.fg-menu-current').parents('ul').size() - 1) * container.width(); Second change: Remove: var checkMenuHeight = function(el) { if (el.height() > options.maxHeight) { el.addClass('fg-menu-scroll') }; el.css({ height: options.maxHeight }); }; Add: var checkMenuHeight = function(el) { var max_height = options.maxHeight - breadcrumb.getTotalHeight(); if (el.height() > max_height) { el.addClass('fg-menu-scroll'); el.height(max_height); topList.height(max_height); } else { if (topList.height() < el.height()) { topList.height(el.height()); } } }; But it's still not working only on Chrome (version 8, Windows & Mac) (not sure why Chrome is different).

  • Why doesn't SuperGenPass work on some sites when I use Chrome?

    - by Lunatik
    Bookmarklet SuperGenPass sometime fails to popup when I click the bookmark in Chrome. It does however work when on the same page works in Firefox; an example is http://www.engadget.com/login This behaviour also replicated on a new Chrome tab (understandably, there is no domain), but some sites just fail to launch it meaning you have to go to another site, open it up, enter in [something] to get the 'Regenerate password' link, enter the domain manually then finally enter your master password to get the generated password! Something about the makeup of the page seems to make SuperGenPass think that it isn't able/required to popup. The FAQ doesn't make any mention of this fact, neither does a quick Google turn up anything that looks relevant. Does anyone else have the same issue? How can it be fixed? I'm on Windows using the current release of Chrome (5.x at the moment, but probably 18.x by the time you read this next week based on Google's seemingly logarithmic release numbering).

  • Validation error while putting <h> tag inside <a> tag(document type does not allow element "h2")

    - by makmour
    when using this code: <div class="menu"> <ul id="mainnav"> <li><h2><a href="dir1/" >AAAAA</a></h2> <ul> <li><a href="dir1/xxx.php"><h3>xxx</h3></a></li> <li><a href="dir1/xxx2.php"><h3>xxx2</h3></a></li> <li><a href="dir1/hxxx3.php"><h3>hxxx3</h3></a></li> </ul> </li> I get an error while validating saying that I should put <h2> outside of <a>. document type does not allow element <h2> When I do this validation passes without any problems but my styling breaks. Is there a way to keep both validation and styling? This is styling for menu and <h2> .menu li a{ font: 100% Helvetica, Arial, sans-serif; display:inline-block; color: #fff; } .menu li a:hover{ color: #014661; background: url('../images/menu1.png') center left no-repeat; } .menu li a h2{ font-size: 92%; padding: 8px 18px; font-weight: bold; text-transform: uppercase; } .menu h3{ font-size: 87%; font-weight: bold; text-transform: uppercase; } .menu li a h2:hover{ background: url('../images/menu2.png') center right no-repeat; }

  • Sound card issues (High Definition Audio Controller)

    - by Prakash R
    I have a 5-year-old Acer Aspire 4520. Until a month back it was working beautifully on Windows 7 32bit. But then out of the blue, the sound stopped working. I've tried reinstalling the OS 3-4 times. The sound came back a couple of times, but it stopped working after a reboot. Even after installing the sound drivers, I don't see any entry in the Playback tab of the Sound applet in Control Panel. I see a High Definition Audio Controller entry in Device Manager. I disabled and uninstalled it, but Windows reinstalls it automatically. I'll share specific hardware details if anybody here needs to know. The processor is "AMD Athlon(tm) 64 X2 Dual-Core Processor TK-55". Any help would be appreciated.

  • Find all CSS rules that apply to an element

    - by Carl Byström
    Many tools/APIs provide ways of selecting elements of specific classes or IDs. There's also possible to inspect the raw stylesheets loaded by the browser. However, for browsers to render an element, they'll compile all CSS rules (possibly from different stylesheet files) and apply it to the element. This is what you see with Firebug or the WebKit Inspector - the full CSS inheritance tree for an element. How can I reproduce this feature in pure JavaScript without requiring additional browser plugins? Perhaps an example can provide some clarification for what I'm looking for: <style type="text/css"> p { color :red; } #description { font-size: 20px; } </style> <p id="description">Lorem ipsum</p> Here the p#description element have two CSS rules applied: a red color and a font size of 20 px. I would like to find the source from where these computed CSS rules originate from (color comes the p rule and so on).

  • How can I render an in-memory UIViewController's view Landscape?

    - by Aaron
    I'm trying to render an in-memory (but not in hierarchy, yet) UIViewController's view into an in-memory image buffer so I can do some interesting transition animations. However, when I render the UIViewController's view into that buffer, it is always rendering as though the controller is in Portrait orientation, no matter the orientation of the rest of the app. How do I clue this controller in? My code in RootViewController looks like this: MyUIViewController* controller = [[MyUIViewController alloc] init]; int width = self.view.frame.size.width; int height = self.view.frame.size.height; int bitmapBytesPerRow = width * 4; unsigned char *offscreenData = calloc(bitmapBytesPerRow * height, sizeof(unsigned char)); CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef offscreenContext = CGBitmapContextCreate(offscreenData, width, height, 8, bitmapBytesPerRow, colorSpace, kCGImageAlphaPremultipliedLast); CGContextTranslateCTM(offscreenContext, 0.0f, height); CGContextScaleCTM(offscreenContext, 1.0f, -1.0f); [(CALayer*)[controller.view layer] renderInContext:offscreenContext]; At that point, the offscreen memory buffers contents are portrait-oriented, even when the window is in landscape orientation. Ideas?

  • Time tracking similar to Paymo Plus on Debian

    - by aditya menon
    PaymoPlus is free (closed source but no fees) PaymoPlus sits in my System Tray all day, and records every window/tab I open I would like to know if a similar app exists for Debian. Paymo for Windows/Mac has the additional sweet feature of being able to drag and drop working windows/tabs and the time spent into the tasks, but one can live without this. I would at least need to know which tasks got how much time in a 'sum total' calculation so I can enter that time into my Paymo reporting. Any ideas? Paymo does have a desktop widget for Linux but it is a dumb (non-sentient) manual time entry tool, not like Paymo Plus automatically recording everything being done.

  • Creating a dynamic two-column iOS spinning wheel with HTML/Javascript

    - by JSW189
    I am trying to create a dynamic two-column spinning wheel for iOS Safari using this HTML/Javascript wheel. However, I am having trouble getting the value of the first column to change the results of the second column. I have tried using an if statement to get the value of the first variable (var beverage) and add the value of the second column correspondingly. Does anybody know what I am doing wrong/if there is a better approach? function openBirthDate() { var beverage = { 1:'Coffee', 2:'Soda' }; //THIS IS WHERE I'M HAVING TROUBLE var results = SpinningWheel.getSelectedValues(); if (results.values === 1) { var company = { 1:'Starbucks', 2:'Dunkin Donuts' }; } else { var company = { 1:'Coke', 2:'Pepsi' }; } var size = { 1:'Tall', 2:'Grande', 3:'Venti' }; SpinningWheel.addSlot(type, '', 1); SpinningWheel.addSlot(company, '', 1); SpinningWheel.addSlot(size, '', 1); SpinningWheel.setCancelAction(cancel); SpinningWheel.setDoneAction(done); SpinningWheel.open(); } function done() { var results = SpinningWheel.getSelectedValues(); document.getElementById('result').innerHTML = 'values: ' + results.values.join(' ') + '<br />keys: ' + results.keys.join(', '); } function cancel() { document.getElementById('result').innerHTML = 'cancelled!'; } window.addEventListener('load', function(){ setTimeout(function(){ window.scrollTo(0,0); }, 100); }, true);

  • How to zoom IFRAME content only without using a frame set?

    - by Baskaran
    I need to zoom frame content only. Here in my web page I used zoom: 0.75; height: 520px; width: 800px;. If I increase the zoom value it means that the frame size will be increased. <HTML> <HEAD> <TITLE> New Document </TITLE> <STYLE> #frame { width: 800px; height: 520px; border: 1px solid black; } #frame { zoom: 0.75; -moz-transform: scale(0.75); -moz-transform-origin: 0 0; } </STYLE> </HEAD> <BODY> <IFRAME id="frame" src="http://www.google.com"></IFRAME> </BODY> </HTML> In the above sample HTML page I want to zoom the content of the IFRAME without changing the size of that IFRAME.

  • alternatives to roboform

    - by ldigas
    Yes, I know there is already a few similar questions. Is there an alternative to RoboForm (which for some reason makes my FF very slow, because of some other extensions) which has the same way of working. What I mean, you click on ... and it opens a new tab with the page in question, and logs on to it (so no databases, and such ...). One other advantage would be if it kept passwords locally. Basically, I'm looking for RoboForm other than RoboForm. Anyone knows of any ?

  • Why am I getting this error when overriding an inherited method?

    - by Sergio Tapia
    Here's my parent class: public abstract class BaseFile { public string Name { get; set; } public string FileType { get; set; } public long Size { get; set; } public DateTime CreationDate { get; set; } public DateTime ModificationDate { get; set; } public abstract void GetFileInformation(); public abstract void GetThumbnail(); } And here's the class that's inheriting it: public class Picture:BaseFile { public override void GetFileInformation(string filePath) { FileInfo fileInformation = new FileInfo(filePath); if (fileInformation.Exists) { Name = fileInformation.Name; FileType = fileInformation.Extension; Size = fileInformation.Length; CreationDate = fileInformation.CreationTime; ModificationDate = fileInformation.LastWriteTime; } } public override void GetThumbnail() { } } I thought when a method was overridden, I could do what I wanted with it. Any help please? :)

  • how to put header authentication into a form using php?

    - by SkyWookie
    Hey guys, for the page I am doing needs a login authentication using Twitter (using tweetphp API). For test purposes I used this code below to do a successful login: if (!isset($_SERVER['PHP_AUTH_USER'])){ header('WWW-Authenticate: Basic realm="Enter your Twitter username and password:"'); header('HTTP/1.0 401 Unauthorized'); echo 'Please enter your Twitter username and password to view your followers.'; exit(); } $username = $_SERVER['PHP_AUTH_USER']; $password = $_SERVER['PHP_AUTH_PW']; The problem now is, I want to integrate it into a form, so far I have the following: <form action="logincheck.php" method="post" class="niceform" > <fieldset> <legend>Twitter Login:</legend> <dl> <dt><label for="email">Twitter Username:</label></dt> <dd><input type="text" name="username" id="username" size="32" maxlength="128" /></dd> </dl> <dl> <dt><label for="password">Password:</label></dt> <dd><input type="password" name="password" id="password" size="32" maxlength="32" /></dd> </dl> </fieldset> <fieldset class="action"> <input type="submit" name="submit" id="submit" value="Submit" /> I am sending it to logincheck.php, this is where I think I get stuck. I am not sure how to compare the form data with Twitter's login data. I was trying a similar if statement as I used in the first code (box that pops up before page loads), but I couldn't wrap my head around it. Thanks again guys!

  • Why is Chrome receiving data?

    - by Aero
    Chrome seems to be continually receiving data even though I'm not downloading anything. This is making a noticeable impact on my browsing speed. The first screenshot shows Chrome receiving data even though I'm not downloading anything (nor buffering a YouTube video etc.) Even after I completely close Google Chrome, the "chrome.exe" remains in the Resource Monitor list and the "Received bytes" column continually increases in the screenshot below. However, "chrome.exe" does not show up in the Processes tab of Task Manager. This only occurs sometimes, but I don't know why. I have tried running a malware/virus scans to ensure that there is nothing malicious behind this, but those scans have shown nothing. Any ideas on what's causing this?

  • Memory efficient collection class

    - by Joe
    I'm building an array of dictionaries (called keys) in my iphone application to hold the section names and row counts for a tableview. the code looks like this: [self.results removeAllObjects]; [self.keys removeAllObjects]; NSUInteger i,j = 0; NSString *key = [NSString string]; NSString *prevKey = [NSString string]; if ([self.allResults count] > 0) { prevKey = [NSString stringWithString:[[[self.allResults objectAtIndex:0] valueForKey:@"name"] substringToIndex:1]]; for (NSDictionary *theDict in self.allResults) { key = [NSString stringWithString:[[theDict valueForKey:@"name"] substringToIndex:1]]; if (![key isEqualToString:prevKey]) { NSDictionary *newDictionary = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithInt:i],@"count", prevKey,@"section", [NSNumber numberWithInt:j], @"total",nil]; [self.keys addObject:newDictionary]; prevKey = [NSString stringWithString:key]; i = 1; } else { i++; } j++; } NSDictionary *newDictionary = [NSDictionary dictionaryWithObjectsAndKeys: [NSNumber numberWithInt:i],@"count", prevKey,@"section", [NSNumber numberWithInt:j], @"total",nil]; [self.keys addObject:newDictionary]; } [self.tableview reloadData]; The code works fine first time through but I sometimes have to rebuild the entire table so I redo this code which orks fine on the simulator, but on my device the program bombs when I execute the reloadData line : malloc: *** mmap(size=3772944384) failed (error code=12) *** error: can't allocate region *** set a breakpoint in malloc_error_break to debug malloc: *** mmap(size=3772944384) failed (error code=12) *** error: can't allocate region *** set a breakpoint in malloc_error_break to debug Program received signal: “EXC_BAD_ACCESS”. If I remove the reloadData line the code works on the device. I'm wondering if this is something to do with the way I've built the keys array (ie using autoreleased strings and dictionaries).

  • Constructor being called again?

    - by Halo
    I have this constructor; public UmlDiagramEntity(ReportElement reportElement, int pageIndex, Controller controller) { super(reportElement.getX1(), reportElement.getY1(), reportElement.getX2(), reportElement.getY2()); setLayout(null); this.pageIndex = pageIndex; this.controller = controller; reportElements = reportElement.getInternalReportElements(); components = new ArrayList<AbstractEntity>(); changedComponentIndex = -1; PageListener p = new PageListener(); this.addMouseMotionListener(p); this.addMouseListener(p); setPage(); } And I have an update method in the same class; @Override public void update(ReportElement reportElement) { if (changedComponentIndex == -1) { super.update(reportElement); } else { reportElements = reportElement.getInternalReportElements(); if (components.size() == reportElements.size()) { if (!isCommitted) { if (reportElement.getType() == ReportElementType.UmlRelation) { if (checkInvolvementAndSet(changedComponentIndex)) { anchorEntity(changedComponentIndex); } else { resistChanges(changedComponentIndex); } return; } } ..................goes on When I follow the flow from the debugger, I see that when update is called, somewhere in the method, the program goes into the constructor and executes it all over again (super, pageIndex, etc.). Why does it go to the constructor :D I didn't tell it to go there. I can make a deeper analysis and see where it goes to the constructor if you want. By the way, changedComponentIndex is a static variable.

  • How do I cast a void pointer to a struct in C?

    - by Rowhawn
    In a project I'm writing code for, I have a void pointer, "implementation", which is a member of a "Hash_map" struct, and points to an "Array_hash_map" struct. The concepts behind this project are not very realistic, but bear with me. The specifications of the project ask that I cast the void pointer "implementation" to an "Array_hash_map" before I can use it in any functions. My question, specifically is, what do I do in the functions to cast the void pointers to the desired struct? Is there one statement at the top of each function that casts them or do I make the cast every time I use "implementation"? Here are the typedefs the structs of a Hash_map and Array_hash_map as well as a couple functions making use of them. typedef struct { Key_compare_fn key_compare_fn; Key_delete_fn key_delete_fn; Data_compare_fn data_compare_fn; Data_delete_fn data_delete_fn; void *implementation; } Hash_map; typedef struct Array_hash_map{ struct Unit *array; int size; int capacity; } Array_hash_map; typedef struct Unit{ Key key; Data data; } Unit; functions: /* Sets the value parameter to the value associated with the key parameter in the Hash_map. */ int get(Hash_map *map, Key key, Data *value){ int i; if (map == NULL || value == NULL) return 0; for (i = 0; i < map->implementation->size; i++){ if (map->key_compare_fn(map->implementation->array[i].key, key) == 0){ *value = map->implementation->array[i].data; return 1; } } return 0; } /* Returns the number of values that can be stored in the Hash_map, since it is represented by an array. */ int current_capacity(Hash_map map){ return map.implementation->capacity; }

  • Javascript to fire event when a key pressed on the Ajax Toolkit Combo box.

    - by Paul Chapman
    I have the following drop down list which is using the Ajax Toolkit to provide a combo box <cc1:ComboBox ID="txtDrug" runat="server" style="font-size:8pt; width:267px;" Font-Size="8pt" DropDownStyle="DropDownList" AutoCompleteMode="SuggestAppend" AutoPostBack="True" ontextchanged="txtDrug_TextChanged" /> Now I need to load this up with approx 7,000 records which takes a considerable time, and effects the response times when the page is posted back and forth. The code which loads these records is as follows; dtDrugs = wsHelper.spGetAllDrugs(); txtDrug.DataValueField = "pkDrugsID"; txtDrug.DataTextField = "drugName"; txtDrug.DataSource = dtDrugs; txtDrug.DataBind(); However if I could get an event to fire when a letter is typed instead of having to load 7000 records it is reduced to less than 50 in most instances. I think this can be done in Javascript. So the question is how can I get an event to fire such that when the form starts there is nothing in the drop down, but as soon as a key is pressed it searches for those records starting with that letter. The .Net side of things I'm sure about - it is the Javascript I'm not. Thanks in advance

  • Gnome keyboard shortcuts dysfunctional after waking up from sleep

    - by dennis2008
    Hello, I am using Ubuntu 9.10 on my Thinkpad T61. Very often after the system woke up from sleep, all the gnome shortcuts went dead (no effect when key combinations pressed). Things like "Alt+F4, Alt+TAB" are dead; things like Ctrl+C/Ctrl+V are OK; buttons such as volume up/down also OK; I tried to Google for answers but wasn't lucky enough. Any idea how to solve it? Thanks! If it's not preventable, can I at least restore them without restarting the session?
