  • Should I really use a UITableView in this situation?

    - by mystify
    Imagine you have a view like this: At the top, there is an UISegmentedControl with two segments. It functions like a tab. Pressing one segment will activate this particular content below that UISegmentedControl. Below the UISegmentedControl are some switches. These modify the way how the content should be rendered. And finally, below those switches, there's a table. Imagine a table not in sense of UITableView, but just what it really is: A table. It shows little messages like twitter messages or chat messages for example, one below the other. Like you know it from skype and other chats. Basically they're just rows with some formatting. A label, some image views, some lines, a background. Pretty basic. The data comes from an array. No core data. The whole thing including the segmented control and setup switches must be scrollable. So what I did is: I put all this stuff in an UIScrollView. Now I have to make the decision if I would use a UITableView inside there for that table part, or if I would just print a lot of rows on to the scroll view (with -drawRect:). But some problems stick in my head: Can I put a UITableView inside a UIScrollView? I assume this makes a lot of problems. I don't want that the table part is separately scrollable. Again imagine that view: First there are some basic choice things (segmented control, switches). Then there comes the table. When you scroll, the whole thing scrolls. That's mainly because this first part with the settings can be pretty big, so you would want to scroll it away. The next thing is: Can I customize UITableView in such a way, that it consists of two parts? One for that settings part, and one for the actual data to display?

  • Display issues on new OpenSUSE install

    - by user1319182
    I installed OpenSUSE 13.1 on my newly built PC, but the display is just horrible : the edges of the screen are missing. For example, I can't see all the top part, I can barely read the date and I see "ctivities" instead of "Activities". However, when I take a screenshot everything seems to be fine (the cursor doesn't appear though) the characters are sometimes too big and sometimes too small the cursor is huge and many other strange things. I took a few pictures I'm using an Intel integrated GPU (HD4400) and made all the possible updates with YaST. Any idea how I can fix this? Thanks

  • How do I fix font corruption in Google Chrome 9.0.597.44beta in Windows XP?

    - by snicker
    I am not sure what is causing this problem, but I think it is related to unicode problems. Google Chrome, seemingly out of nowhere a month ago, stopped rendering unicode characters in certain fonts. IE this ?_? Looks fine in some fonts, but looks like this in others. Renders fine in other browsers. Most recently, I visited the FourSquare website and have complete font corruption. Here is IE vs Chrome Full Size What gives? Has anyone else seen this? How can I fix it?

  • Consecutive absences in MySQL

    - by pepersview
    Hi, I have 2 tables in my db: students and absences. In students: id_student, s_name; and in absences: id_student, date, day(the day of the week as number-it's not so important); I would like to get the students that were absent for more than 2 days consecutive and the dates. At the moment I have the next query: /*To control when the days are in the same week*/ SELECT id_student, date, dayname(date),date_add(date, INTERVAL 1 DAY) AS a, dayname(date_add(date, INTERVAL 1 DAY)) AS an, date_add(date, INTERVAL 2 DAY) AS b, dayname(date_add(date, INTERVAL 2 DAY)) AS bn FROM absences AS a WHERE id_student IN (SELECT id_student FROM absences WHERE id_student = a.id_student AND date = date_add(a.date, INTERVAL 1 DAY) ) AND id_student IN (SELECT id_student FROM absences WHERE id_student = a.id_student AND date = date_add(a.date,INTERVAL 2 DAY) ) UNION /*To control when the days jump to the next week*/ SELECT id_student, date, dayname(date),date_add(date, INTERVAL 3 DAY) AS a, dayname(date_add(date, INTERVAL 3 DAY)) AS an, date_add(date, INTERVAL 4 DAY) AS b, dayname(date_add(date, INTERVAL 4 DAY)) AS bn FROM absences AS a WHERE id_student IN (SELECT id_student FROM absences WHERE id_student = a.id_student AND date = date_add(a.date, INTERVAL 3 DAY) ) AND id_student IN (SELECT id_student FROM absences WHERE id_student = a.id_student AND date = date_add(a.date,INTERVAL 4 DAY) ) /* To avoid the case (Monday-Thursday-Friday) to be consider as consecutive days*/ AND WEEKDAY(date) !=0 Thanks

  • Excel VLOOKUP using results from a formula as the lookup value [on hold]

    - by Rick Deemer
    I have a cell that I must remove the first 2 characters "RO" for each value in a column on a sheet called RAW DATA and put into a cell on a sheet called ROSS DATA. Some of the values in that cell have 3 digits after the "RO", and some have 5 digits. To do that I used =REPLACE('RAW DATA'!A3,1,2,"") Then I need to use this new resultant string as the lookup value in a VLOOKUP. The VLOOKUP will be looking at a named range called DAP on a sheet called DAP, in column 5 for an exact match, and I need it to return that value to the cell. I have tried using INDIRECT in different ways to no avail, and I'm not sure that I fully understand its usage. So at this point I am Googling for a method to do this and at a standstill.

  • Why changing the images name on server results in calling the old ones?

    - by moderns
    I am running a slideshow on Ubuntu 12.04.1 that loads the images (slide1.jpg, slide2.jpg, slide3.jpg.., slide5.jpg) using the Javascript and styles as below: document.getElementById('slide_area').className='slide'+step; .slide1{background-image: url(../upload/slide1.jpg)} .slide2{background-image: url(../upload/slide2.jpg)} .slide3{background-image: url(../upload/slide3.jpg)} .slide4{background-image: url(../upload/slide4.jpg)} .slide5{background-image: url(../upload/slide5.jpg)} When I change the images names (show1.jpg, show2.jpg, show3.jpg.., show5.jpg) and also change the style as below: .slide1{background-image: url(../upload/show1.jpg)} .slide2{background-image: url(../upload/show2.jpg)} .slide3{background-image: url(../upload/show3.jpg)} .slide4{background-image: url(../upload/show4.jpg)} .slide5{background-image: url(../upload/show5.jpg)} And open the network section on Chrome, I see the server is calling the new name and old name for images! I added the header in the index.php: header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0"); header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the past header("Cache-Control: post-check=0, pre-check=0", false); header("Pragma: no-cache"); Nothing worked out with me and the slideshow doesn't work properly when I change the name of images even when clearing the browser cache as I load images sequentially (one by one) depending on imageObject.complete property! But without changing the name everything is going perfect and the images are loaded smoothly! Thank you for your help!

  • Dictionary-based text auto-completion in Windows (i.e. Mozilla Thunderbird e-mail client)?

    - by None
    Most programmer's text editors and IDEs have it, automatic completion of the first few characters (letters) of a keyword or function name. Also, most address bars or search fields feature this (like the tag input below the posting form). I would like the same for a few, often-occuring words in business correspondance. Since I could not find an extension for the application in question, Mozilla Thunderbird, I would like to know if there are applications or methods that suggest the complete words from a dictionary like sup per eruser erfluent PS: Here's an article on Wikipedia: Word completion Here's a product for $25: Type Booster Ideally, the solution is free.

  • What is the worst gotcha in WPF?

    - by David
    Hi, I've started to make myself a list of "WPF gotchas": things that bug me and that I had to write down to remember because I fall for them every time.... Now, I'm pretty sure you all stumbled upon similar situations at one point, and I would like you to share your experience on the subject: What is the gotcha that gets you all the time? the one you find the most annoying? (I have a few issues that seem to be without explanation, maybe your submissions will explain them) Here are a few of my "personnal" gotchas (randomly presented): For a MouseEvent to be fired even when the click is on the "transparent" background of a control (e.g. a label) and not just on the content (the Text in this case), the control's Background has to be set to "Brushes.Transparent" and not just "null" (default value for a label) A WPF DataGridCell's DataContext is the RowView to whom the cell belong, not the CellView When inside a ScrollViewer, a Scrollbar is managed by the scrollviewer itself (i.e. setting properties such as ScrollBar.Value is without effect) Key.F10 is not fired when you press "F10", instead you get Key.System and you have to go look for e.SystemKey to get the Key.F10 ... and now you're on.

  • How do I offset centered text (without fancy CSS, DHTML, etc.)?

    - by Larry
    Hi, Quick, hopefully easy question. Google is failing me. I don't want my text exactly centered. I want it maybe 7 characters (blank spaces) over. What do I add to this to do that? <.centerThis is centered<./center Adding blanks in front of the "T" does nothing. (I added the dots in the code above because I can't get <.code blocks/spans to let me put the html code here.) (Nothing fancy - no CSS, DHTML, XHTML - just plain old HTML.) Thanks.

  • Why won't AVI2DVD load the audio stream?

    - by Xavierjazz
    XP SP3 I have an .avi file. It is in a folder on my "C:" drive. There are no disallowed characters in either the folder or file name. It has audio as I have watched it on my computer. I want to burn it to a DVD. When I load the file into AVI2DVD, no audio stream shows, and the program will not work without an audio stream. I have used the net extensively to try and solve this, with no success. AFICT I have followed all instructions exactly, but no audio stream. Very frustrating. Does anyone have a clue? Can you help me? Thank you. Regards,

  • Should the program logic reside inside the gui object class or be external to the class?

    - by hd112
    I have a question about how to structure code in relation to GUI objects. Suppose I have a dialog that has a list control that has a bunch of names obtained from a database. The user can edit the names. Does the logic reside inside that dialog class or should it be from the outside. To illustrate what I mean, here’s some pseudo code showing the structure of the code when the logic is handled outside the dialog class: NamesDialog : wxDialog { Private: ..stuff.. Public: ... SetNames(wxStringArray names); wxStringArray GetNames(); ..stuff.. } So the user of the class would do something like: wxStringArray names = DatabaseManager::Get()->GetNames(); names.Sort(); NamesDialogObject.SetNames(names); NamesDialogObject.ShowModal(); wxStringArray modified_names = NamesDialogObject.GetNames(); AddToDatabase(modified_names); //or something like this. On the other hand, the database logic can reside inside the NamesDialog class itself. In the show method I can query the database for the names and as the user interacts with the controls (list control in this case), the database can be updated from the event handlers. As a result the NamesDialog class only has the Show() method as there is no need to use SetNames or GetNames() etc. Which method is generally preferred? I don’t have much work experience so I’m not sure which is the proper way to handle it. Sometimes it's easier to handle everything in the class but getting access to objects it interacts with can be challenging. Generally can do it by having the relevant objects be singletons like the database manager in the above example.

  • dotNet Templated, Repeating, Databound ServerControl: Counting the templates OnDataBind?

    - by Campbeln
    I have a server control that wraps an underlying class which manages a number of indexes to track where it is in a dataset (ie: RenderedRecordCount, ErroredRecordCount, NewRecordCount, etc.). I've got the server control rendering great, but OnDataBinding I'm having an issue as to seems to happen after CreateChildControls and before Render (both of which properly manage the iteration of the underlying indexes). While I'm somewhat familiar with the ASP.NET page lifecycle, this one seems to be beyond me at the moment. So... how do I hook into the iterative process OnDataBinding uses so I can manage the underlying indexes? Will I have to iterate over the ITemplates myself, managing the indexes as I go or is there an easier solution? Also... I implemented the iteration of the underlying indexes during CreateChildControls originally in the belief that was the proper place to hook in for events like OnDataBinding (thining it was done as the controls were being .Add'd). Now it seems that this may actually be unnecessary. So I guess the secondary question is: What happens during CreateChildControls? Are the unadulterated (read: with <%-tags in place) controls added to the .Controls collection without any other processing?

  • What's the easiest way to change the contents of text in a string with C#?

    - by Anne
    I have HTML in a string that looks like this: <div id="control"> <a href="/xx/x">y</a> <ul> <li><a href="/C003Q/x" class="dw">x</a></li> <li><a href="/C003R/xx" class="dw">xx</a></li> <li><a href="/C003S/xxx" class="dw">xxx</a></li> </ul> </div> I would like to change this to the following: <div id="control"> <a data-href="/xx/x" ><span>y</span></a> <ul> <li><a data-href="/C003Q/x" class="dw"><span>x</span></a></li> <li><a data-href="/C003R/xx" class="dw"><span>xx</span></a></li> <li><a data-href="/C003S/xxx" class="dw"><span>xxx</span></a></li> </ul> </div> I heard about regex but I am not sure how I can use it to change something inside the address tags and to change href at the same time. Would I need to use regex twice and can I change the inside of the <a ... >...</a> using regex or is there an easier way with C#?

  • Sharing class member data between sub components

    - by Tim Gradwell
    I have an aggregate 'main' class which contains some data which I wish to share. The main class also has other class members. I want to share the data with these other class members. What is the correct / neatest way to do this? The specific example I have is as follows. The main class is a .net Form. I have some controls (actually controls within controls) on the main form which need access to the shared data. Main Form - DataX - DataY - Control1 -- Subcontrol1 - Control2 -- SubControl2 SubControls 1 and 2 both wish to access DataX and DataY. The trouble is, I feel like better practice (to reduce coupling), would be that either subcontrols should not know about Main Form, or Main Form should not know about subcontrols - probably the former. For subcontrols not to know about Main Form, would probably mean Main Form passing references to both Controls 1 and 2, which in turn would pass the references on to SubControls 1 and 2. Lots of lines of code which just forward the references. If I later added DataZ and DataW, and Controls 3 and 4 and SubControls 3 and 4, I'd have to add lots more reference forwarding code. It seems simpler to me to give SubControls 1 and 2 member references to Main Form. That way, any sub control could just ask for MainForm.DataX or MainForm.DataY and if I ever added new data, I could just access it directly from the sub controls with no hassle. But it still involves setting the 'MainForm' member references every time I add a new Control or Subcontrol. And it gives me a gut feeling of 'wrong'. As you might be able to tell I'm not happy with either of my solutions. Is there a better way? Thanks

  • Is there a Form.Invoke() method?

    - by rubicon
    Hi, I am new to multithreading (and also to C#) so I hope this is not obvious: In my Form (WinForms application, .NET 2.0) I subscribed to an event that is raised by another object, and on handling this event I wish to change several Controls on my Form. As this event is raised in another thread than the main (UI) thread I want to marshal the call to the Form's thread. I understand I could use the Control.Invoke() method on any Control that I want to change, but as there are several of them I do not wish to do that. When searching the internet I found hints that the Form class itself provides an Invoke() method. See for example: http://marioschneider.blogspot.com/2008/04/invoke-methode-fr-multithread.html (Sorry, as I am I new user I can't seem to post more than one link. I will add more links as comments if possible.) With that, I could just wrap my event handler and then use it as if it was called on the UI thread. However, this doesn't seem to be defined in my environment, and in MSDN's System.Windows.Forms.Form documentation there's also no sign of it. Does this method exist in the .NET-Framework? I find it hard to believe that Form would not supply such a method, as it uses the same message queue the Controls on it do. (Or am I missing something here?)

  • WPF Databinding With A Collection Object

    - by Randster
    Argh, although I've been googling, I really would appreciate it if someone could break my problem down as all the code examples online are confusing me more than assisting (perhaps it's just late)... I have a simple class as defined below: public class Person { int _id; string _name; public Person() { } public int ID { get { return _id; } set { _id = value; } } public string Name { get { return _name; } set { _name = value; } } } that is stored in a database, and thru a bit more code I put it into an ObservableCollection object to attempt to databind in WPF later on: public class People : ObservableCollection<Person> { public People() : base() { } public void Add(List<Person> pListOfPeople) { foreach (Person p in pListOfPeople) this.Add(p); } } In XAML, I have myself a ListView that I would like to populate a ListViewItem (consisting of a textblock) for each item in the "People" object as it gets updated from the database. I would also like that textblock to bind to the "Name" property of the Person object. I thought at first that I could do this: lstPeople.DataContext = objPeople; where lstPeople is my ListView control in my XAML, but that of course does nothing. I've found TONS of examples online where people through XAML create an object and then bind to it through their XAML; but not one where we bind to an instantiated object and re-draw accordingly. Could someone please give me a few pointers on: A) How to bind a ListView control to my instantiated "People" collection object? B) How might I apply a template to my ListView to format it for the objects in the collection? Even links to a decent example (not one operating on an object declared in XAML please) would be appreciated. Thanks for your time.

  • OOP + MVC advice on Member Controller

    - by dan727
    Hi, I am trying to follow good practices as much as possible while I'm learning using OOP in an MVC structure, so i'm turning to you guys for a bit of advice on something which is bothering me a little here. I am writing a site where I will have a number of different forms for members to fill in (mainly data about themselves), so i've decided to set up a Member controller where all of the forms relating to the member are represented as individual methods. This includes login/logout methods, as well as editing profile data etc. In addition to these methods, i also have a method to generate the member's control panel widget, which is a constant on every page on the site while the member is logged in. The only thing is, all of the other methods in this controller all have the same dependencies and form templates, so it would be great to generate all this in the constructor, but as the control_panel method does not have the same dependencies etc, I cannot use the constructor for this purpose, and instead I have to redeclare the dependencies and same template snippets in each method. This obviously isn't ideal and doesn't follow DRY principle, but I'm wondering what I should do with the control_panel method, as it is related to the member and that's why I put it in that controller in the first place. Am I just over-complicating things here and does it make sense to just move the control_panel method into a simple helper class? Here are the basic methods of the controller: class Member_Controller extends Website_Controller { public function __construct() { parent::__construct(); if (request::is_ajax()) { $this->auto_render = FALSE; // disable auto render } } public static function control_panel() { //load control panel view $panel = new View('user/control_panel'); return $panel; } public function login() { } public function register() { } public function profile() { } public function household() { } public function edit_profile() { } public function logout() { } }

  • XML in Authorware 7.01

    - by Mikael
    Let me explain the setup that is being used. Right now I have an authorware program which loads an ocx control. This control receives data in the form on an XML string. This part is working properly. However I need parse this XML string in authorware and have not been successful. I have been trying to use the XMLParser Xtra. The documentation listed here shows how to create a new XMLParser object and then shows how to call the object but never explains how to link the Parser to a XML file or XML string. The information I have been using can be found here https://www.adobe.com/livedocs/authorware/7/using_aw_en/wwhelp/wwhimpl/common/html/wwhelp.htm?context=Using_Authorware_7&file=09_va110.htm#224295 I need more information on how to Parse XML with this function or if there is another way to do this in Authorware. As a side note the documentation says it cannot create or append to XML, I will need to do this also inside of Authorware. Is this possible and if so, how?

  • Why won't my code segfault on Windows 7?

    - by Trevor
    This is an unusual question to ask but here goes: In my code, I accidentally dereference NULL somewhere. But instead of the application crashing with a segfault, it seems to stop execution of the current function and just return control back to the UI. This makes debugging difficult because I would normally like to be alerted to the crash so I can attach a debugger. What could be causing this? Specifically, my code is an ODBC Driver (ie. a DLL). My test application is ODBC Test (odbct32w.exe) which allows me to explicitly call the ODBC API functions in my DLL. When I call one of the functions which has a known segfault, instead of crashing the application, ODBC Test simply returns control to the UI without printing the result of the function call. I can then call any function in my driver again. I do know that technically the application calls the ODBC driver manager which loads and calls the functions in my driver. But that is beside the point as my segfault (or whatever is happening) causes the driver manager function to not return either (as evidenced by the application not printing a result). One of my co-workers with a similar machine experiences this same problem while another does not but we have not been able to determine any specific differences.

  • Apache Rewrite Rules

    - by Philip
    I have moved my website from a Wiki to Wordpress and in the process, realised that I have broken links to some popular pages on my website. Is it possible to fix this with a rewrite rule? I need the rule to redirect anything beginning with "^/wiki/(.+)$" to "/$1" but also replacing the "_" character used in MediaWiki slugs to "-" used in Wordpress slugs. For example: http://example.com/wiki/An_Example_Page should be pointed to: http://example.com/an-example-page Is it possible to write such a rewrite rule? Edit: It appears that Wordpress doesn't even care if the "/wiki/" part is removed - provided the slug matches, and that seems to be case-insensitive too. So all I need to do is change the "_" characters to "-" in the slugs.

  • How to test which button is stuck

    - by Macha
    My laptop's keyboard is prone to buttons sticking. The fix is to just press the same button again. Now when it is the letter/number keys are stuck, it's just a matter of putting the cursor in a text field, and seeing what characters appear. However, when it is one of the modifier keys, or tab, or enter or a few other buttons, it gets harder to tell which key is to blame. Trying to type can result in all sort of shortcuts being triggered. Is there anyway to test what input is being recieved? Also, I'm guessing this is a hardware issue, but if anyone knows of any possible causes/solutions it'd be appreciated. It's a Dell Studio 17, and the problem occurs under Windows and Linux.
