  • How do I get SSIS Data Flow to put '0.00' in a flat file?

    - by theog
    I have an SSIS package with a Data Flow that takes an ADO.NET data source (just a small table), executes a select * query, and outputs the query results to a flat file (I've also tried just pulling the whole table and not using a SQL select). The problem is that the data source pulls a column that is a Money datatype, and if the value is not zero, it comes into the text flat file just fine (like '123.45'), but when the value is zero, it shows up in the destination flat file as '.00'. I need to know how to get the leading zero back into the flat file. I've tried various datatypes for the output (in the Flat File Connection Manager), including currency and string, but this seems to have no effect. I've tried a case statement in my select, like this: CASE WHEN columnValue = 0 THEN '0.00' ELSE columnValue END (still results in '.00') I've tried variations on that like this: CASE WHEN columnValue = 0 THEN convert(decimal(12,2), '0.00') ELSE convert(decimal(12,2), columnValue) END (Still results in '.00') and: CASE WHEN columnValue = 0 THEN convert(money, '0.00') ELSE convert(money, columnValue) END (results in '.0000000000000000000') This silly little issue is killin' me. Can anybody tell me how to get a zero Money datatype database value into a flat file as '0.00'?

  • A couple of questions on exceptions/flow control and the application of custom exceptions

    - by dotnetdev
    1) Custom exceptions can help make your intentions clear. How can this be? The intention is to handle or log the exception, regardless of whether the type is built-in or custom. The main reason I use custom exceptions is to not use one exception type to cover the same problem in different contexts (eg parameter is null in system code which may be effect by an external factor and an empty shopping basket). However, the partition between system and business-domain code and using different exception types seems very obvious and not making the most of custom exceptions. Related to this, if custom exceptions cover the business exceptions, I could also get all the places which are sources for exceptions at the business domain level using "Find all references". Is it worth adding exceptions if you check the arguments in a method for being null, use them a few times, and then add the catch? Is it a realistic risk that an external factor or some other freak cause could cause the argument to be null after being checked anyway? 2) What does it mean when exceptions should not be used to control the flow of programs and why not? I assume this is like: if (exceptionVariable != null) { } Is it generally good practise to fill every variable in an exception object? As a developer, do you expect every possible variable to be filled by another coder?

  • LinearLayout not expanding inside a ScrollView

    - by Felix
    I have a LinearLayout inside a ScrollView that has android:layout_height="fill_parent", but it doesn't expand to the full height of the ScrollView. My layout looks something like: level layout layout_width layout_height 1 LinearLayout fill_parent fill_parent 2 LinearLayout fill_parent wrap_content 3 (some irrelevant stuff) 2 ScrollView fill_parent fill_parent <-- this expands full height 3 LinearLayout fill_parent fill_parent <-- this does not (has orientation=vertical) (following stuff probably are irrelevant, but just to be sure:) 4 TextView fill_parent fill_parent 4 LinearLayout fill_parent wrap_content I can see that the LinearLayout doesn't expand the full height of the ScrollView because in Eclipse in Android Layout Editor, if I select the ScrollView (in the Outline panel) it is highlighted with a red border that fills the screen to the bottom but when I select the LinearLayout its highlight doesn't expand to the bottom of the screen. How can I get it to do so? The effect I'm trying to achieve is to have some text and a button below it (inside the LinearLayout in level 4 there's just a button). The text can be big enough to need a scrollbar, in which case I want the user to have to scroll down in order to see the button. In case the text is not big enough for a scroll bar, I want the LinearLayout containing the button to stick to the bottom of the screen.

  • JOGL Double Buffering

    - by Bar
    What is eligible way to implement double buffering in JOGL (Java OpenGL)? I am trying to do that by the following code: ... /** Creating canvas. */ GLCapabilities capabilities = new GLCapabilities(); capabilities.setDoubleBuffered(true); GLCanvas canvas = new GLCanvas(capabilities); ... /** Function display(…), which draws a white Rectangle on a black background. */ public void display(GLAutoDrawable drawable) { drawable.swapBuffers(); gl = drawable.getGL(); gl.glClear(GL.GL_COLOR_BUFFER_BIT | GL.GL_DEPTH_BUFFER_BIT); gl.glClearColor(0.0f, 0.0f, 0.0f, 0.0f); gl.glColor3f(1.0f, 1.0f, 1.0f); gl.glBegin(GL.GL_POLYGON); gl.glVertex2f(-0.5f, -0.5f); gl.glVertex2f(-0.5f, 0.5f); gl.glVertex2f(0.5f, 0.5f); gl.glVertex2f(0.5f, -0.5f); gl.glEnd(); } ... /** Other functions are empty. */ Questions: — When I'm resizing the window, I usually get flickering. As I see it, I have a mistake in my double buffering implementation. — I have doubt, where I must place function swapBuffers — before or after (as many sources says) the drawing? As you noticed, I use function swapBuffers (drawable.swapBuffers()) before drawing a rectangle. Otherwise, I'm getting a noise after resize. So what is an appropriate way to do that? Including or omitting the line capabilities.setDoubleBuffered(true) does not make any effect.

  • Blockchain API, AJAX request has stopped working, CORS issues?

    - by Sly
    I've been playing with the multiple address look up API from blockchain info (documented here https://blockchain.info/api/blockchain_api), I had my code working earlier in the day but bizzarely it's stopped. The purpose of it is to eventually write a little JQuery library which will search the DOM for bitcoin addresses as data attributes and then insert the final balance into that element creating a polling mechanism to keep the page updated as well. The original problem I ran into earlier while developing it was because it's a CORS ajax request but later I adjusted the query per the blockchain info API documents and I added cors=true it then seemed to work fine but now it doesn't seem to want to work at all again. I don't get how changing computers would effect this kind of request. Here's my code on JSFiddle, http://jsfiddle.net/SlyFoxy12/9mr7L/7/ My primary code is: (function ($) { var methods = { init: function(data, options) { //put your init logic here. }, query_addresses: function(addresses) { var addresses_implode = addresses.join("|"); $.getJSON("http://blockchain.info/multiaddr?cors=true&active="+addresses_implode, function( data ) { $.each( data.addresses, function( index ) { $('#output').append(" "+data.addresses[index].final_balance); }); }); } }; $.fn.bitstrap = function () { var addresses = new Array(); $('[data-xbt-address]').each(function () { $(this).text($(this).data('xbtAddress')); addresses.push($(this).data('xbtAddress')); }); methods.query_addresses(addresses); } }(jQuery)); $().ready(function() { $().bitstrap(); });

  • Mapping interface or abstract class component

    - by Yann Trevin
    Please consider the following simple use case: public class Foo { public virtual int Id { get; protected set; } public virtual IBar Bar { get; set; } } public interface IBar { string Text { get; set; } } public class Bar : IBar { public virtual string Text { get; set; } } And the fluent-nhibernate map class: public class FooMap : ClassMap<Foo> { public FooMap() { Id(x => x.Id); Component(x => x.Bar, m => { m.Map(x => x.Text); }); } } While running any query with configuration, I get the following exception: NHibernate.InstantiationException: "Cannot instantiate abstract class or interface: NHMappingTest.IBar" It seems that NHibernate tries to instantiate an IBar object instead of the Bar concrete class. How to let Fluent-NHibernate know which concrete class to instantiate when the property returns an interface or an abstract base class? EDIT: Explicitly specify the type of component by writing Component<Bar> (as suggested by Sly) has no effect and causes the same exception to occur. EDIT2: Thanks to vedklyv and Paul Batum: such a mapping should be soon is now possible.

  • Select the latest record for each category linked available on an object

    - by Simpleton
    I have a tblMachineReports with the columns: Status(varchar),LogDate(datetime),Category(varchar), and MachineID(int). I want to retrieve the latest status update from each category for every machine, so in effect getting a snapshot of the latest statuses of all the machines unique to their MachineID. The table data would look like Category - Status - MachineID - LogDate cata - status1 - 001 - date1 cata - status2 - 002 - date2 catb - status3 - 001 - date2 catc - status2 - 002 - date4 cata - status3 - 001 - date5 catc - status1 - 001 - date6 catb - status2 - 001 - date7 cata - status2 - 002 - date8 catb - status2 - 002 - date9 catc - status2 - 001 - date10 Restated, I have multiple machines reporting on multiple statuses in this tblMachineReports. All the rows are created through inserts, so their will obviously be duplicate entries for machines as new statuses come in. None of the columns can be predicted, so I can't do any ='some hard coded string' comparisons in any part of the select statement. For the sample table I provided, the desired results would look like: Category - Status - MachineID - LogDate catc - status2 - 002 - date4 cata - status3 - 001 - date5 catb - status2 - 001 - date7 cata - status2 - 002 - date8 catb - status2 - 002 - date9 catc - status2 - 001 - date10 What would the select statement look like to achieve this, getting the latest status for each category on each machine, using MS SQL Server 2008? I have tried different combinations of subqueries combined with aggregate MAX(LogDates)'s, along with joins, group bys, distincts, and what-not, but have yet to find a working solution.

  • Why use short-circuit code?

    - by Tim Lytle
    Related Questions: Benefits of using short-circuit evaluation, Why would a language NOT use Short-circuit evaluation?, Can someone explain this line of code please? (Logic & Assignment operators) There are questions about the benefits of a language using short-circuit code, but I'm wondering what are the benefits for a programmer? Is it just that it can make code a little more concise? Or are there performance reasons? I'm not asking about situations where two entities need to be evaluated anyway, for example: if($user->auth() AND $model->valid()){ $model->save(); } To me the reasoning there is clear - since both need to be true, you can skip the more costly model validation if the user can't save the data. This also has a (to me) obvious purpose: if(is_string($userid) AND strlen($userid) > 10){ //do something }; Because it wouldn't be wise to call strlen() with a non-string value. What I'm wondering about is the use of short-circuit code when it doesn't effect any other statements. For example, from the Zend Application default index page: defined('APPLICATION_PATH') || define('APPLICATION_PATH', realpath(dirname(__FILE__) . '/../application')); This could have been: if(!defined('APPLICATION_PATH')){ define('APPLICATION_PATH', realpath(dirname(__FILE__) . '/../application')); } Or even as a single statement: if(!defined('APPLICATION_PATH')) define('APPLICATION_PATH', realpath(dirname(__FILE__) . '/../application')); So why use the short-circuit code? Just for the 'coolness' factor of using logic operators in place of control structures? To consolidate nested if statements? Because it's faster?

  • Core Animation problem on iPhone

    - by Mac
    I'm new to iPhone development, and doing some experimentation with Core Animation. I've run into a small problem regarding the duration of the animation I'm attempting. Basically, Ive got a view with two subviews, and I'm trying to animate their opacity so that one fades in while the other fades out. Problem is, instead of a gradual fade in/out, the subviews simply switch instantly to/from full/zero opacity. I've tried to adjust the animation duration with CATransaction with no noticable effect. It's also not specific to animating opacity - animating position shows the same problem. The code I'm using (inside a method of the superview) follows: CALayer* oldLayer = ((UIView*) [[self subviews] objectAtIndex:0]).layer; CALayer* newLayer = ((UIView*) [[self subviews] objectAtIndex:1]).layer; [CATransaction begin]; [CATransaction setAnimationDuration:1.0f]; oldLayer.opacity = 0.0; newLayer.opacity = 1.0; [CATransaction commit]; Does anyone have an idea what the problem might be?

  • PHP: Detect encoding and make everything UTF-8

    - by marco92w
    Hello! I'm reading out lots of texts from various RSS feeds and inserting them into my database. Of course, there are several different character encodings used in the feeds, e.g. UTF-8 and ISO-8859-1. Unfortunately, there are sometimes problems with the encodings of the texts. Example: 1) The "ß" in "Fußball" should look like this in my database: "Ÿ". If it is a "Ÿ", it is displayed correctly. 2) Sometimes, the "ß" in "Fußball" looks like this in my database: "ß". Then it is displayed wrongly, of course. 3) In other cases, the "ß" is saved as a "ß" - so without any change. Then it is also displayed wrongly. What can I do to avoid the cases 2 and 3? How can I make everything the same encoding, preferably UTF-8? When must I use utf8_encode(), when must I use utf8_decode() (it's clear what the effect is but when must I use the functions?) and when must I do nothing with the input? Can you help me and tell me how to make everything the same encoding? Perhaps with the function mb-detect-encoding()? Can I write a function for this? So my problems are: 1) How to find out what encoding the text uses 2) How to convert it to UTF-8 - whatever the old encoding is Thanks in advance! EDIT: Would a function like this work? function correct_encoding($text) { $current_encoding = mb_detect_encoding($text, 'auto'); $text = iconv($current_encoding, 'UTF-8', $text); return $text; } I've tested it but it doesn't work. What's wrong with it?

  • How to disable Power off/Power on sound on Android phone? [closed]

    - by yvolk
    My Android phone (Android v.2.1) produces loud sound both before Power off and after Power on (boot) is being completed. I don't want to turn the sound off before reboot/powering it off and to turn sound on after reboot every time I'm restarting my phone. I just want to get rid of these sounds forever :-) How can I do this (maybe executing some script, changing some properties... preferably without rooting my phone)? Update: Thank you Christopher Orr! I've also found some information that partially allows to achieve what I'm looking for (on androidforums.com): "if you are going into SettingsSound & displayNotification ringtone that sets your notification tone for app updates, power on (rebooting) etc. If you want to change notification for messages you would have to go into messaging and then hit the menu key for notification option. You can do the same for email accounts as well." So I disabled Power on/off sounds (plus something else... but I didn't notice undesired side effect yet...) with built-in settings.

  • wxOSX/Carbon: wxGLCanvas mouse offset in non-floating window classes

    - by srose
    Hi All, I mainly program plugins using wxWidgets within a Carbon bundle which is loaded at runtime. The host-applications where my plugins are running in provide a native window handle (WindowRef), which I can use to add my custom, wxWidgets-based GUI-classes. To use the native window handle with wxWidgets classes I had to write a wxTopLevelWindow wrapper class, which does all the WindowRef encapsulation. So far, this works pretty well, but under some circumstances I got vertical mouse offsets within a wxGLCanvas if the window class of the native window handle is not of the type "kFloatingWindowClass". I am able to bypass the problem if I display an info panel (wxPanel) over the whole wxGlCanvas and if the user hides the info panel then the mouse offset is gone. Now my questions: Is there a "simple" explanation for this behaviour? Is it possible to use certain method calls to imitate info panel effect without using the panel itself? I tried several combinations of Update() and Refresh() calls of all involved components, but none of them worked so far. Even the use of wxSizer couldn't help here. Window hierarchy used by plugin-applications: wxCustomTopLevelWindow (WindowRef provided by host-application) wxPanel (parent window for all application panel) wxPanel (application info panel) wxPanel (application main panel) wxPanel (opengl main panel) wxGlCanvas (main opengl canvas) Any ideas? Any help is very appreciated.

  • Flex, Ant, mxmlc and conditional compilation

    - by Rezmason
    My ActionScript project builds with several compile-time specified constants. They are all Booleans, and only one of them is true at any given time. The rest must be false. When I represented my build process in a bash script, I could loop through the names of all these constants, set one of them to be true and the rest to be false, then concatenate them onto a string to be inserted as a set of arguments passed to mxmlc. In Ant, looping is more complicated. I've tried the ant-contrib for tag: <mxmlc file='blah' output='blah'> <!- ... -> <for list='${commaSeparatedListOfConstNames}' param='constName'> <sequential> <define> <name>${constName}</name> <value>${constName} == ${theTrueConst}</value> <!-- (mxmlc's define arguments can be strings that are evaluated at compile time) --> </define> </sequential> </for> </mxmlc> Long story short, ant-contrib tags like the for tag can't go in the mxmlc task. So now I'm using Ant's propertyregex to take my list of arguments and format them into a set of define args, like my old bash script: <propertyregex property='defLine.first' override='false' input='${commaSeparatedListOfConstNames}' regexp='([^\|]+)\,' replace='\1,false ' /> <propertyregex property='defLine.final' input='${defLine.first}' regexp='(@{theTrueConst}\,)false' replace='\1true' /> <!-- result: -define+=CONST_ONE,false -define+=CONST_TWO,false -define+=TRUE_CONST,true --> Now my problem is, what can I do with this mxmlc argument and the mxmlc task? Apparently arg tags can go inside the mxmlc task without it throwing an error, but they don't seem to have any effect. What am I supposed to do? How do I make this work with the mxmlc task?

  • Custumizing Syntax Highlighting in Vim

    - by sixtyfootersdude
    Hey I have defined a few custom file types for vim. I have done this like this: In vimrc: au BufWinEnter,BufRead,BufNewFile *.jak set filetype=jak And then in jak.vim syn match arrows /<-/ syn match arrows /->/ syn match arrows /=>/ syn match arrows /<=/ highlight arrows ctermfg=brown ... This works. (Formatting applies to any file opened with vim with file extension .jak) My question is how I can keep all the current formatting for a file type but add functionality. For example I would like to add this functionality for .vim files: syn keyword yellow yellow highlight yellow ctermfg=yellow ... (so that I can see how my terminal interpenetrates different colors before choosing them.) I have created ~/.vim/syntax/vim.vim (file only contains the above) and put this into my vimrc: au BufWinEnter,BufRead,BufNewFile *.vim set filetype=vim This has no effect. The word yellow is not colored yellow. I have also tried putting my vim.vim file into ~/.vim/after/syntax/vim.vim As suggested here This is the approach that I would like to take. Seems clean and easily maintainable.

  • UITableView scrolling to specific position

    - by Dave
    I am using iPhone SDK 3.1.3. I have a UITableViewController which gets data from another controller. The tableview is added as a subview to the mainview but the frame is set so that it is not visible. The tableview frame is updated and made to slide over the main view by tapping on a button. The table view appears and i scroll to the last row. if i select the last row, i reload the table with more data. The table gets updated with more data. everything works fine except the scroll position is always the top. I need the scroll position to be the last row that I clicked on to load more data. I save the scroll position and call the following code after it loads more data. It executes without issues but the scroll position is always the top. [theTableView scrollTRowAtIndexPath:[NSIndexPath indexPathForRow:savedScrollPosition inSection:0] atScrollPosition:savedScrollPosition animated:NO]; The above seems to have no effect. ViewWillAppear: ViewDidAppear: does not fire and I am told that if the view controller is instantiated in code, which is the case, these don't fire.

  • apache: cgi links lead to a "you have chosen to open foo.cgi", although scriptalias is set

    - by Xiong Chiamiov
    Following this guide on CentOS 5.2, just getting nagios set up for the first time. The main page shows up just fine, but when I try to view any of the pages that should be generated by a cgi process, firefox prompts me to save the .cgi instead, so apache's obviously not understanding that it needs to run the cgi and get back some html from it. The odd thing is, though, that, as far as I can tell, apache should be running these files as cgi. nagios.conf: # SAMPLE CONFIG SNIPPETS FOR APACHE WEB SERVER # Last Modified: 11-26-2005 # # This file contains examples of entries that need # to be incorporated into your Apache web server # configuration file. Customize the paths, etc. as # needed to fit your system.

This config file is being parsed by apache, because if I move it out of conf.d, /nagios gives a 404. The .cgi files are indeed in the /nagios/cgi-bin/ directory, so I didn't specify the incorrect directory. Searching seemed to only provide people who had difficulty with permissions, which is not the issue here. This seems to me to be a pretty basic thing, but even with the excellent apache documentation, I'm at a bit of a loss (been using cherokee too much lately :) ).

  • jQuery.width() & DOM refresh

    - by o_O Tync
    My script dynamically creates a <ul> width left-floating <li>s inside: it's a paginator. Afterwards, the script measures width of all <li>s and summs them up. The problem is that after the nodes are injected into the document — the browser refreshed DOM and applies CSS styles which takes a while. It has a negative effect on my script: when these operations are not complete before I measure the width — my script gets a wrong value. If I perform the measure in a second — everything is ok. The thing I'm looking for is a way to detect the moment when the <ul> is fully drawn, styles applied and the width has stabilizes. Or at least a way to detect every dimensions changes. If there's a way to detect width stabilization — I would do the measuring right after it to get the correct values. P.S. Why I need this. My paginator's left-floating <li> items tend to move to the next line when the <ul> tries to become wider than the page itself. Even though most of <li>s are invisible because of parent <div>'s width restriction: div { width: 500px; overflow: hidden; } div ul { width: 100%; white-space: nowrap; } div ul li { display: block; float: left; } they still go down unless I specify the actual summed width of the <ul> with the script.

  • GXT LayoutContainer with scrollbar reports a client height value which includes the area below the s

    - by Pieter Breed
    I have this code which sets up a "main" container into which other modules of the application will go. LayoutContainer c = new LayoutContainer(); c.setScrollMode(Scroll.ALWAYS); parentContainer.add(c, <...>); Then later on, I have the following as an event handler pContainer = c; // pContainer is actually a parameter, but it has c's value pContainer.removeAll(); pContainer.setLayout(new FitLayout()); LayoutContainer wrapperContainer = new LayoutContainer(); wrapperContainer.setLayout(new BorderLayout()); wrapperContainer.setBorders(false); pContainer.add(wrapperContainer); LayoutContainer west = pWestContentContainer; BorderLayoutData westLayoutData = new BorderLayoutData(LayoutRegion.WEST); westLayoutData.setSize(pWidth); westLayoutData.setSplit(true); wrapperContainer.add(west, westLayoutData); LayoutContainer center = new LayoutContainer(); wrapperContainer.add(center, new BorderLayoutData(LayoutRegion.CENTER)); pCallback.withSplitContainer(center); pContainer.layout(); So in effect, the container called 'west' here will be where the module's UI gets displayed. That module UI then does a simple rowlayout with two children. The botton child has RowData(1, 1) so it fills up all the available space. My problem is that the c (parent) container reports a height and width value which includes the value underneath the scrollbars. What I would like is that the scrollbars show all the space excluding their own space. This is a screenshot showing what I mean:

  • Some questions about slugs in ASP.NET MVC content system

    - by mare
    In my application I'm currently using forms which allow to enter Title and Slug fields. Now I've been struggling with the slugs thing for a while because I can never decide once and for all how to handle them. 1) Make Title and Slug indenpendent Should I allow users to enter both Title and Slug separetely? This is what I had first. I also had an option that if user did not enter the Slug it was derived from the Title. If both were enter, the Slug field took precedence. 2) Derive Slug from Title, when content is inserted that's it for the Slug, no more changes Then, I switched to only Title field and derive Slug from title. While doing it I found out that now I have to change all the forms that allowed user to enter a slug. This way of doing it also prevents users to change Slugs - they can change the Title but it has no effect on the Slug. You can think of it like Slug is uniqued ID. 3) Now I'm thinking again of allowing users to change slug Though I don't think it is all that useful. How many times does the content that someone already added, spent time on writing it, even require a change of either Title or slug? I don't think it is that many times. The biggest problem with the 3rd option is that If I use Slugs as IDs, I need to update the reference all over the place when Slug changes. Or maintain a table that would contain somekind of Slug history. What are you thoughts on these, I hope, valid questions?

  • .NET 4 RTM MetadataType attribute ignored when using Validator

    - by bart
    I am using VS 2010 RTM and trying to perform some basic validation on a simple type using MetadataTypeAttribute. When I put the validation attribute on the main class, everything works. However, when I put it on the metadata class, it seems to be ignored. I must be missing something trivial, but I've been stuck on this for a while now. I had a look at the Enterprise Library validation block as a workaround, but it doesn't support validation of single properties out of the box. Any ideas? class Program { static void Main(string[] args) { Stuff t = new Stuff(); try { Validator.ValidateProperty(t.X, new ValidationContext(t, null, null) { MemberName = "X" }); Console.WriteLine("Failed!"); } catch (ValidationException) { Console.WriteLine("Succeeded!"); } } } [MetadataType(typeof(StuffMetadata))] public class Stuff { //[Required] //works here public string X { get; set; } } public class StuffMetadata { [Required] //no effect here public string X { get; set; } }

  • Updating CoreData xcdatamodel file troubles - attribute type change

    - by San
    I noticed several questions related to this topic go unanswered. Is this such a gray area that nobody really understands it? Here is my problem: I am a midway in the development of my app and the app has never been used ouside of my iphone simulator.One of the attributes in my core data structure requires a type change.Since my app has never been used outside of my iPhone Simulator, I first deleted the sqlite file. Doubling the effort of this step, I also went into iPhone Simulator menu and selected "Reset Content and Settings...". Than, I edited the xcdatamodel file and changed the type of my attribute. I saved the file and exited. Without any other changes, I compiled. I expected it to fail because of my type change. It did not! After this, I assigned a value with new type to my attribute and it fails to compile?! Is there something else that I need to do for the change to take an effect? I would really, really appreciate an answer to my question. Thank you!

  • IE7 CSS bug aligning <img> with text in a <ul>

    - by Artem Russakovskii
    I've been banging my ahead on this IE7 bug for the last few days and it's time to resort to the mind of the crowd. I have the following HTML and CSS: http://beerpla.net/for_www/ie7_test/test.html The goal is to have a <ul>, with each <li> containing a small icon and some text. Multiline text would be aligned to itself and not wrap under the image. I've tried using float:left on the image and a bunch of other things, and finally I thought the position:absolute would work for sure but in IE7 I consistently see the text pop off to the next line and get misaligned with the image: This is what I expect it to look like: I even tried to make the div display:inline which kind of worked but then started wrapping under the image for long lines, so it was no good. zoom:1 also produced a similar effect. I'm at a loss at the moment. This code works fine in all other browsers. IE7 is a special, very special child. Any ideas? Thank you. Edit: If you have IE8, you can emulate IE7 by pressing F12 and then Alt-7.

  • iPhone User Interface Design

    - by Blaenk
    Hey guys, I've just had a nagging question for a while regarding iPhone app user interfaces. For example, consider WeightBot's User Interface. I am wondering, how are most of these user interfaces created? In general, of course. Is there a way to simply design controls (that is, the images) in a program like Photoshop, then use that 'skin' for controls in UIKit? I realize that there are some controls that are probably created by the programmer (custom controls), but I'm referring to the ready-made ones that come in UIKit. In other words, is the concept similar to 'splicing' web site designs? Where a designer draws out the design of the website in something like Photoshop, and then it is cut up into pieces which can be applied to form the actual website? I know this can be done for UIButtons, can this also be done for other controls, and is this how it is usually done? Or perhaps this is done with Core Animation? I've heard this from time to time, so does this mean that the User Interfaces are 'hard-coded'? Or is Core Animation only use for the 'effects', such as applying the glowing effect to the numbers in WeightBot? If there are any resources you can point me to I would really appreciate it. Thanks!

  • Command /Developer/usr/bin/dsymutil failed with exit code 10

    - by Evan Robinson
    I am getting the above error message randomly (so far as I can tell) on iPhone projects. Occasionally it will go away upon either: Clean Restart XCode Reboot Reinstall XCode But sometimes it won't. When it won't the only solution I have found is to take all the source material, import it into a new project, and then redo all the connections in IB. Then I'm good until it strikes again. Anybody have any suggestions? [update 20091030] I have tried building both debug and release versions, both full and lite versions. I've also tried switching the debug symbols from DWARF with external dSYM file to DWARF and to stabs. Clean builds in all formats make no differences. Permission repairs change nothing. Setting up a new user has no effect. Same error on the builds. Thanks for the suggestions! [Update 20091031] Here's an easier and (apparently) reliable workaround. It hinges upon the discovery that the problem is linked to a target not a project In the same project file, create a new target Option-Drag (copy) all the files from the BAD target 'Copy Bundle Resources' folder to the NEW target 'Copy Bundle Resources' folder Repeat (2) with 'Compile Sources' and 'Link Binary With Libraries' Duplicate the Info.plist file for the BAD target and name it correctly for the NEW target. Build the NEW target! [Update 20100222] Apparently an IDE bug, now apparently fixed, although Apple does not allow direct access to the original bug of a duplicate. I can no longer reproduce this behaviour, so hopefully it is dead, dead, dead.

  • Putting a MovieMaterial behind a DAE model in Papervision3D

    - by didibus
    Hi, I'm doing a project using FLARManager augmented reality and the Papervision3D library. Unfortunately, Papervision is giving me a lot of problems. My scene3D contains a DAE model and a plane. The plane has a MovieMaterial and is playing a video through FLVPlayback. The DAE and the plane are both inside the same DisplayObject3D container. FLARManager transforms the container so that everything appears through the angle of the marker. My DAE model is a TV, the screen of the TV is transparent. I want to have my Plane inside of my DAE model, so that the Movie playing on the plane material appears to be what is playing on the TV. The problem is that, even if the plane has a lower Z index then the TV, it always appears in front of the TV. How do I have my plane and its MovieMaterial appear behind the TV, so that some of its corners are cut out by the TV and the part of the TV thats transparent let me see the Movie? If its impossible, anyone has an idea of how I could get the desired effect of having a movie play on the screen of my DAE tv model? Thank You.
