  • can I auto update my uitextview from the value of the row of my uipickerview without pressing any se

    - by Wesley
    So I have a uipicker view, that I have managed to load some data from my db into. I would like to update a textview, which is right above the pickerview, with each changing of the row. Is that possible? If I don't have to, I would like to avoid pushing a button in order to show the respective text. Can I make it so that the value in the text field changes with the value of the rowselected in the pickerview, in real time? Any thoughts or code snippets would be appreciated. Thanks!

  • How to set width of textbox to be same as MaxLength in ASP.NET

    - by John Galt
    Is there a way I can limit the width of a textbox to be equal to the MaxLength property? In my case right now, the textbox control is placed in a table cell as in this snippet: <td class=TDSmallerBold style="width:90%"> <asp:textbox id="txtTitle" runat="server" CausesValidation="true" Text="Type a title here..be concise but descriptive. Include price." ToolTip="Describe the item with a short pithy title (most important keywords first). Include the price. The title you provide here will be the primary text found by search engines that index Zipeee content." MaxLength="60" Width="100%"> </asp:textbox> (I know I should not use HTML tables to control layout..another subject for sure) but is there a way to constrain the actual width to the max number of characters allowed in the typed box?

  • Reverse rendering of Urdu fonts

    - by Syed Muhammad Umair
    I am working on a project that is based on Urdu language in Ubuntu platform. I'm using Python language and have almost achieved my task. The problem is that, the Urdu text is rendered in reverse order. For example, consider the word ??? (which means work) consisting of the three letters: ? , ? , and ? The output is rendered in reverse order as ??? consisting of the three letters: ?, ?, and ? When copying this text to Open Office or opening the generated XML file in Firefox, the generated result is absolutely desired. I Am using Python 2.6 IDLE, its working perfect with Windows platform, which clearly shows its not the problem of IDLE. Am working on TKINTER GUI library. How can this problem be solved?

  • MySQL - Sort on a calculated value based on two dates

    - by Petter Magnusson
    I have the following problem that needs to be solved in a MySQL query: Fields info - textfield date1 - a date field date2 - a date field offset1 - a text field with a number in the first two positions, example "10-High" offset2 - a text field with a number in the first two positions, example "10-High" I need to sort the records by the calculated "sortvalue" based on the current date (today): If today=date2 then sortvalue=offset1*10+offset2*5+1000 else sortvalue=offset1*10+offset2*5 I have quite good understanding of basic SQL with joins etc, but this I am not even sure if its possible...if it helps I could perhaps live with a single formula giving the same sort of effect as the IFs do....ie. before date1 = low value, after date2 = high value...

  • Problem with Replacing special characters in a string

    - by Hossein
    Hi, I am trying to feed some text to a special pupose parser. The problem with this parser is that it is sensitive to ()[] characters and in my sentence in the text have quite a lot of these characters. The manual for the parser suggests that all the ()[] get replaced with \( \) \[ \]. So using str.replace i am using to attach \ to all of those charcaters. I use the code below: a = 'abcdef(1234)' a.replace('(','\(') however i get this as my output: 'abcdef\\(1234)' What is wrong with my code? can anyone provide me a solution to solve this for these characters?

  • Save UITextView content in NSString.

    - by camilo
    Hi, I'm trying to save the contents of an UITextView into a NSString which I will somehow persist later. The problem is that the UITextView "text" property doesn't save all the rows in the textView (after touching "return"). I tried print the TextView object and the textView.text, and they're different. Does anybody know how (after editing the textView) I can save its content into a String (or something else that I can later access and share through different views and persist in the database)? Thanks a lot. Pretty sure it is simple, but I'm honestly not finding the solution.

  • getElementsByTagName problem in chrome and safari

    - by Ilian Iliev
    I`m parsing a Google Maps RSS with javascript and using the following code to get the point coordinates: point_coords = items.getElementsByTagName('georss:point') Unfortunately it works in FF but not in safari and chrome (still not tested in Opera and IE) The XML looks like: <item> <guid isPermaLink="false">guidNo</guid> <pubDate>Mon, 23 Mar 2009 20:16:41 +0000</pubDate> <title>title text</title> <description><![CDATA[text]]></description> <author>UniCreditBulbank</author> <georss:point> 42.732342 23.296659 </georss:point> </item>

  • Popup browser incompability

    - by Cornelis
    I have a popup with drop down menus on it. I've scaled it down and simplified it for test purposes, but it still doesn't work the way I want/it should. <!DOCTYPE html> <html> <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script> <script type="text/javascript"> jQuery(document).ready(function(){ jQuery('.trigger').click(function(){ var picker = jQuery('.popup'); jQuery('<div></div>').css({ height: screen.height, width: screen.width, position: 'absolute', 'z-index': -1, top: picker.offset().top*-1, left: picker.offset().left*-1, border: '1px solid red' }).click(function(){ picker.trigger('focusout'); jQuery(this).hide(); }).prependTo(picker); picker.css('visibility', 'visible'); }); jQuery('.popup').live("focusout", function() { jQuery('.popup').fadeTo(500, 0.0, function() { jQuery('.popup').css('visibility', 'hidden'); jQuery('.popup').css('opacity', '1.0'); }); }); }); </script> </head> <body> <p> <input type=text class=trigger /> <div id=popup-div class=popup style="visibility: hidden; border: 1px solid red"> <select> <option>option1</option> </select> <p>Popup text</p> </div> </p> </body> When you click on the input field, a 'popup' appears, if you click outside the red border it fades away. If you click on the select option it shouldn't dissappear! However on this point, Chrome doesn't work the same as IE/FF/Opera/Safari, and makes the div dissappear. (Using Chrome 4.0.295.0) Does anybody knows a work-around for Chrome? Calling event.stopPropagation() on select elements did not work so far

  • Must I loop to search results for a specific value?

    - by tag
    I have a table in the database: name Opinion Tim Tim has an opinion John other random text Dan Dan's random text Al Al says something else I call this data and get it back in getRecords.lastResult To access John's opinion, I could use: getRecords.lastResult[1].opinion But that's only because I know that John is the second record (record 1), but this may change. So the right way is to search through the results to first find the record index for John, then access his opinion. My guess is I need some sort of a loop? Is there an easier way to search for John directly without a loop?

  • Help me understand this C code

    - by Benjamin
    INT GetTree (HWND hWnd, HTREEITEM hItem, HKEY *pRoot, TCHAR *pszKey, INT nMax) { TV_ITEM tvi; TCHAR szName[256]; HTREEITEM hParent; HWND hwndTV = GetDlgItem (hWnd, ID_TREEV); memset (&tvi, 0, sizeof (tvi)); hParent = TreeView_GetParent (hwndTV, hItem); if (hParent) { // Get the parent of the parent of the... GetTree (hWnd, hParent, pRoot, pszKey, nMax); // Get the name of the item. tvi.mask = TVIF_TEXT; tvi.hItem = hItem; tvi.pszText = szName; tvi.cchTextMax = dim(szName); TreeView_GetItem (hwndTV, &tvi); //send the TVM_GETITEM message? lstrcat (pszKey, TEXT ("\\")); lstrcat (pszKey, szName); } else { *pszKey = TEXT ('\0'); szName[0] = TEXT ('\0'); // Get the name of the item. tvi.mask = TVIF_TEXT | TVIF_PARAM; tvi.hItem = hItem; tvi.pszText = szName; tvi.cchTextMax = dim(szName); if (TreeView_GetItem (hwndTV, &tvi)) //*pRoot = (HTREEITEM)tvi.lParam; //original hItem = (HTREEITEM)tvi.lParam; else { INT rc = GetLastError(); } } return 0; } The block of code that begins with the comment "Get the name of the item" does not make sense to me. If you are getting the listview item why does the code set the parameters of the item being retrieved? If you already had the values there would be no need to retrieve them. Secondly near the comment "original" is the original line of code which will compile with a warning under embedded visual c++ 4.0, but if you copy the exact same code into visual studio 2008 it will not compile. Since I did not write any of this code, and am trying to learn, is it possible the original author made a mistake on this line? The *pRoot should point to HKEY type yet he is casting to an HTREEITEM type which should never work since the data types don't match?

  • XSL: Dead or not dead

    - by Seattle Leonard
    I'm currently taking on a new project at home. In this project I'm going to be generating HTML emails. For this purpose, I believe XSL to be a good candidate. However, I have heard people say that XSL is a dead language, and if it's not that it is on it's way out. In fact, MS has been very leary to support XSL 2.0. Personally I feel that any time you are going from text to text, it is a great tool. Such as: Generating HTML e-mails Creating Open Office Docs Generating another XML doc What are your thoughts? Is it dead, or is it still a viable, usefull tool?

  • How to subString a block of user generated HTML while preserving formatting?

    - by Chad
    I'd like to create the typical preview paragraph with a [read more] link. Problem is, the content that I'd like to SubString() contains text and html, written by a user with a WYSIWYG editor. Of course, I check to make sure the string is not null or empty, then SubString() it, problem is that I could end up breaking the html tags, throwing off the rendering of the entire site. The WYSIWYG editor doesn't seem to create perfectly formatted HTML, and many times seems to use <br /> tags instead of <p></p>, etc... basically, I can't rely on well-formed tags, etc. My workaround was to just strip out all HTML and substring the leftover text. This works, but loses any of the formatting that was in the HTML. What's the best method of SubString()'ing a block of non-well-formed HTML while maintaining HTML that won't break the rendering of the site?

  • ASP.NET MVC - Disable Html Helper control using boolean value from Model

    - by The Matt
    I am outputting a textbox to the page using the Html helpers. I want to add the disabled attribute dynamically based on whether or not a boolean value in my model is true or false. My model has a method that returns a boolean value: <% =Model.IsMyTextboxEnabled() %> I currently render the textbox like follows, but I want to now enabled or disable it: <% =Html.TextBox("MyTextbox", Model.MyValuenew { id = "MyTextbox", @class = "MyClass" })%> If the return value of Model.IsMyTextboxEnabled() == true I want the following to be output: <input class="MyClass" id="MyTextbox" name="MyTextbox" type="text" value="" /> If it == false, I want it to output as: <input class="MyClass" id="MyTextbox" name="MyTextbox" type="text" value="" disabled /> What is the cleanest way to do this?

  • mediawiki markup equivalent of WMD live-previewing editor? (not WYSIWYG)

    - by Justin Grant
    Anyone have a recommendation for an editor like the WMD editor, but using MediaWiki markup instead of Markdown? Our site is already using MediaWiki markup but we want a slicker editor without changing markup completely. Requirements include: live preview of formatted text underneath the markup you're typing a toolbar for common formatting (bold, italic, links, bullets, numbered-list, code, etc) keyboard shortcuts for each toolbar button (e.g. CTRL+B for bold) Undo/redo via keyboard shortcuts (CTRL+Z/CTRL+Y) or toolbar buttons works well in the usual set of popular browsers (including IE6!) open-source would be preferred I've found a few options at http://www.mediawiki.org/wiki/WYSIWYG_editor, but all of these seem to be WYSIWYG editors which is not exactly what I want since full-on WYSIWYG editors tend to be bug-prone and complicate working at the markup level. Instead we want a plain-text markup editor with a client-side previewer, plus some UI niceties (toolbar, undo, keyboard shortcuts) to make editing markup easier.

  • Using Markov models to convert all caps to mixed case and related problems

    - by hippietrail
    I've been thinking about using Markov techniques to restore missing information to natural language text. Restore mixed case to text in all caps Restore accents / diacritics to languages which should have them but have been converted to plain ASCII Convert rough phonetic transcriptions back into native alphabets That seems to be in order of least difficult to most difficult. Basically the problem is resolving ambiguities based on context. I can use Wiktionary as a dictionary and Wikipedia as a corpus using n-grams and Markov chains to resolve the ambiguities. Am I on the right track? Are there already some services, libraries, or tools for this sort of thing?

  • as3 formatting a textfield

    - by duckofrubber
    Hi, I'm dynamically creating textfields in as3, and formatting them with the TextFormat class. I'm having some issues though with selecting the exact "style" of font to apply to the textfields. My code so far looks like: formatT = new TextFormat( ); formatT.bold = false; formatT.color = 0x000000; formatT.font = "TradeGothic"; formatT.size = 16; var textItem = new TextField(); textItem.text = "foobar"; textItem.setTextFormat(formatT); addChild(textItem); This works ("Trade Gothic" is applied to the enclosed text), however I can't figure out how to apply a specific style of "Trade Gothic", for instance "Light Oblique". Is there some way that I can specify this using the TextFormat class? Thanks.

  • Create list-of-controls in Windows.Forms

    - by leiflundgren
    I have decided that I would like to have a list with "complex context", i.e. of custom-controls. (The goal is something looking like a buddy list, with photos, status-icons, text, "start-chat-button".) But I like it to behave as a list: scrollbars, possibility to select multiple items etc. When I have been looking at ListView and ListBox I only see that I can add text and an icon, but not arbitrary controls. I'm I missing how this is done? Or should I use something else then ListView/ListBox?

  • Oracle: show parameters on error

    - by llappall
    When Oracle logs a parameterized SQL query failing, it shows "?" in place of the parameters, i.e. the query before replacing parameters. For example, "SELECT * FROM table where col like '?'" SQL state [99999]; error code [29902]; ORA-29902: error in executing ODCIIndexStart() routine ORA-20000: Oracle Text error: DRG-50901: text query parser syntax error on line 1, column 48 Is there a way to change logging so it shows the parameter values? The information above is absolutely useless unless I can see what the actual parsing problem was. In general, is there a way to set logs in Oracle to show parameters in parameterized query errors?

  • Limit JavaScript and CSS files on ASP.NET MVC 2 Master Page based on Model and View content

    - by Zack Peterson
    I want to include certain .js and .css files only on pages that need them. For example, my EditorTemplate DateTime.ascx needs files anytimec.js and anytimec.css. That template is applied whenever I use either the EditorFor or EditorForModel helper methods in a view for a model with a DateTime type value. I've put this condition into the <head> section of my master page. It checks for a DateTime type property in the ModelMetadata. <% if (this.ViewData.ModelMetadata.Properties.Any(p => p.ModelType == typeof(DateTime))) { %> <link href="../../Content/anytimec.css" rel="stylesheet" type="text/css" /> <script src="../../Scripts/anytimec.js" type="text/javascript"></script> <% } %> This has two problems: Fails if I have nested child models of type DateTime Unnecessarily triggered by views without EditorFor or EditorForModel methods (example: DisplayForModel) How can I improve this technique?
