  • Finding first alphabetic character in a DB2 database field

    - by Paul Alan Taylor
    I'm doing a bit of work which requires me to truncate DB2 character-based fields. Essentially, I need to discard all text which is found at or after the first alphabetic character. e.g. 102048994BLAHBLAHBLAH becomes:- 102048994 In SQL Server, this would be a doddle - PATINDEX would swoop in and save the day. Much celebration would ensue. My problem is that I need to do this in DB2. Worse, the result needs to be used in a join query, also in DB2. I can't find an easy way to do this. Is there a PATINDEX equivalent in DB2? Is there another way to solve this problem? If need be, I'll hardcode 26 chained LOCATE functions to get my result, but if there is a better way, I am all ears.

  • Can I use a class as an object in C# to create instances of that class?

    - by Troy
    I'm writing a fairly uncomplicated program which can "connect" to several different types of data sources including text files and various databases. I've decided to implement each of these connection types as a class inherited from an interface I called iConnection. So, for example, I have TextConnection, MySQLConnection, &c... as classes. In another static class I've got a dictionary with human-readable names for these connections as keys. For the value of each dictionary entry, I want the class itself. That way, I can do things like: newConnection = new dict[connectionTypeString](); Is there a way to do something like this? I'm fairly new to C# so I'd appreciate any help.

  • Problem -- My Android "Hello World" App Won't Say 'Hello"

    - by keith
    Hello, I hope that I have come to the right post for a beginner’s question abut Android programming. If not, please feel free to direct me to a better forum. I created a hello world application, and the system generated most of the Android language below. When running the app without the system.out statement, there is no “hello” in the emulator. Then, using the Eclipse tutorial, I read that I can add the system.out.println statement to main. Again the app runs, but there is no output. What am I not understanding here? android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" System.out.println =" Hello world!" / Thank you, Keith

  • Android: Filtering a SimpleCursorAdapter ListView

    - by Diego Tori
    Right now, I'm running into issues trying to implement a FilterQueryProvider in my custom SimpleCursorAdapter, since I'm unsure of what to do in the FilterQueryProvider's runQuery function. In other words, since the query that comprises my ListView basically gets the rowID, name, and a third column from my databases's table, I want to be able to filter the cursor based on the partial value of the name column. However, I am uncertain of whether I can do this directly from runQuery without expanding my DB class since I want to filter the existing cursor, or will I have to create a new query function in my DB class that partially searches my name column, and if so, how would I go about creating the query statement while using the CharSequence constraint argument in runQuery? I am also concerned about the performance issues associated with trying to run multiple queries based on partial text since the DB table in question has about 1300-1400 rows. In other words, would I run into a bottleneck trying to filter the cursor?

  • ExtJS: Login with 'Remember me' functionality

    - by Chau
    I'm trying to create a simple login window with the very common 'Remember me' functionality. The login validation is done AJAX style, thus the browser won't remember my input. My approach is to use the built-in state functionality, but how to use it confuses me. Ext.state.Manager.setProvider(new Ext.state.CookieProvider({ expires: new Date(new Date().getTime()+(1000*60*60*24*7)), //7 days from now })); ... { xtype: 'textfield', fieldLabel: 'User name', id: 'txt-username', stateful: true, stateId: 'username' }, { xtype: 'textfield', fieldLabel: 'Password', id: 'txt-password', inputType: 'password', stateful: true, stateId: 'password' }, { xtype: 'button', text: 'Validate', stateEvents: 'click' } I know I have to implement the getState method, but on what component (my guess is on the two textfields)? Another thing I fail to realize is, how is my click event on the button connected to the state properties of my textfields?

  • jquery hover not working properly other than IE6

    - by Kranthi
    Hi All, We developed navigation bar using jQuery 1.4.2. Functionality is to show submneus for different menu items when user hovers on it. It is working perfectly in IE6 but we see some weird problems in other browsers. In Firefox, when the page gets loaded, it works fine but when we hit f5, the submenu wont appear on hover. To get submenu we need to click on any other menu item. In Chrome, its the same to add on, some time even we click on any menu item, and hover submenu wont show up. In Safari, nothing shows up most of the times, but on clicking 5-6 menu items, submenu is shown.When we see loading text in safari it shows the submenu. but on every click the loading text wont appear.. We are very much confused..is it the browser behavior/code/jquery?? Below is the snippet: Html: <ul> <li><a class="mainLinks" href="google.com">Support</a> <ul><li>Sublink1</li></ul> </ul> Html code is absolutely fine. Jquery: var timeout = null; var ie = (document.all) ? true : false; $(document).ready(function(){ var $mainLink = null; var $subLink = null; $(".mainLinks").each(function(){ if ($(this).hasClass("current")) { $(this).mouseout(function() { var $this = $(this); timeout = setTimeout(function() { $(".popUpNav", $this.parent()).css({ visibility : 'hidden' }); $('.popUpArrow').hide(); ieCompat('show'); }, 200); }); } else { $(this).hover(function() { reset(); ieCompat('hide'); // Saving this for later use in the popUpNav hover event $mainLink = $(this); $popUpNav = $(".popUpNav", $mainLink.parent()); // Default width is width of one column var popupWidth = $('.popUpNavSection').width() + 20; // Calculate popup width depending on the number of columns var numColumns = $popUpNav.find('.popUpNavSection').length; if (numColumns != 0) { popupWidth *= numColumns; } var elPos = $mainLink.position(); var leftOffset = 0; if (elPos.left + popupWidth > 950) { leftOffset = elPos.left + popupWidth - 948; } $popUpNav.css({ top : elPos.top + 31 + 'px', left : elPos.left - leftOffset + 'px', visibility : 'visible', width : popupWidth + 'px' }); $('.popUpArrow').css({ left : elPos.left + Math.round(($mainLink.width() / 2)) + 20 + 'px', top : '27px' }).show(); }, function() { var $this = $(this); timeout = setTimeout(function() { $(".popUpNav", $this.parent()).css({ visibility : 'hidden' }); $('.popUpArrow').hide() ieCompat('show'); }, 200); } ); } }); $(".subLinks").hover( function(e) { $subLink = $(this); var elPos = $subLink.position(); var popupWidth = $(".popUpNavLv2",$subLink.parent()).width(); var leftOffset = 0; ieCompat('hide'); $(".popUpNavLv2",$subLink.parent()).css({ top : elPos.top + 32 + 'px', left : elPos.left - leftOffset + 'px', visibility : 'visible' }); }, function() { var $this = $(this); timeout = setTimeout(function() { $(".popUpNavLv2", $this.parent()).css({ visibility : 'hidden' }); }, 200); ieCompat('show'); } ); $('.popUpNav').hover( function() { clearTimeout(timeout); $mainLink.addClass('current'); $(this).css('visibility', 'visible'); $('.popUpArrow').show(); }, function() { $mainLink.removeClass('current'); $(this).css('visibility', 'hidden'); $('.popUpArrow').hide(); ieCompat('show'); } ); $('.popUpNavLv2').hover( function() { clearTimeout(timeout); $(this).css('visibility', 'visible'); ieCompat('hide'); }, function() { ieCompat('show'); $(this).css('visibility', 'hidden'); } ); // If on mac, reduce left padding on the tabs if (/mac os x/.test(navigator.userAgent.toLowerCase())) { $('.mainLinks, .mainLinksHome').css('padding-left', '23px'); } }); Thanks a lot in advance for looking into it. Thanks | Kranthi

  • How do I set the Initial Directory on an OpenFileDIalog to the users `Downloads` folder in C#

    - by JMK
    Ok so I have an OpenFileDialog and I want to set the initial directory to the users 'Download' folder. This is an internal application and, therefore, I am sure that the user will be using Windows 7. var ofd = new OpenFileDialog(); //This doesn't work ofd.InitialDirectory = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Personal), "Downloads"); //This doesn't work either ofd.InitialDirectory = @"%USERPROFILE%\Downloads"; ofd.Filter = "Zip Files|*.zip"; ofd.ShowDialog(); txtFooBar.Text = ofd.FileName; I have tried the above so far and neither work. No Exception is thrown, it just doesn't set the initial directory to the downloads folder. Where am I going wrong? Thanks

  • HtmlAgilityPack SelectNodes expression to ignore an element with a certain attribute

    - by thaky
    I am trying to select nodes except from script nodes and a ul that has a class called 'relativeNav'. Can someone please direct me to the right path? I have been searching for this for a week and I can't find it anywhere. Currently I have this but it obviously selecting the //ul[@class='relativeNav'] as well. Is there anyway to put an NOT expression of it so that SelectNode will ignore that one? foreach (HtmlNode node in doc.DocumentNode.SelectNodes("//body//*[not(self::script)]/text()")) { Console.WriteLine("Node: " + node); singleString += node.InnerText.Trim() + "\n"; }

  • Detect backspace in UITextField

    - by marcc
    Is there any way to detect when the backspace/delete key is pressed in the iPhone keyboard on a UITextField that is empty? I want to know when backspace is pressed only if the UITextField is empty. Based on the suggestion from @Alex Reynolds in a comment, I've added the following code while creating my text field: [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleTextFieldChanged:) name:UITextFieldTextDidChangeNotification object:searchTextField]; This notification is received (handleTextFieldChanged function is called), but still not when I press the backspace key in an empty field. Any ideas? There seems to be some confusion around this question. I want to receive a notification when the backspace key is pressed. That's it. But the solution must also work when the UITextField is already empty.

  • A better way of converting Codepage-1251 in RTF to Unicode

    - by blue painted
    I am trying to parse RTF (via MSEDIT) in various languages, all in Delphi 2010, in order to produce HTML in unicode. Taking Russian/Cyrillic as my starting point I find that the overall document codepage is 1252 (Western) but the Russian parts of the text are identified by the charset of the font (RUSSIAN_CHARSET 204). So far I am: 1) Use AnsiString (or RawByteString) when parsing the RTF 2) Determine the CodePage by a lookup from the font charset (see http://msdn.microsoft.com/en-us/library/cc194829.aspx) 3) Translating using a lookup table in my code: (This table generated from http://msdn.microsoft.com/en-gb/goglobal/cc305144.aspx) - I'm going to need one table per supported codepage! There MUST be a better way than this? Preferably something supplied by the OS and so less brittle than tables of constants.

  • Entity Framework: EntityCommand automatically parsing and determine parameter types?

    - by Torben Rahbek Koch
    Hi everybody, Pretty new to Entity Framework I must admit, but I simply cannot believe that there is no built-in solution for this problem. Let's say I create an EntityCommand: EntityCommand cmd = conn.CreateCommand(); cmd.CommandType = CommandType.Text; cmd.CommandText = commandText; And let's say the the commandText is something like this: SELECT sp.UserName, sp.Rights FROM EntityContext.Users as sp WHERE sp.UserName=@UserName Now it would be really neat if the Parameters collection of cmd could be automatically filled. The framework should obviously know the types etc. but I guess that's simply not how it works beneath. The problem is that the commandText is configurable on run-time, and I must show some GUI that asks for values of the parameters. Any idea on how this could be accomplished? Thanks for any ideas and for listening!

  • Ruby on Rails simple_navigation Gem

    - by Paul
    I'm using the simple_navigation gem with RoR 2.3.5 It all seems to work correctly, I followed the info in the RDoc (seen here http://rdoc.info/projects/mexpolk/simple_navigation) However, when I actually render out the simple_navigation menu on my main application.html.erb file it escapes all of the html in it (multiple escapes actually). I end up with junk like this which in a browser ends up with all kinds of disjointed text and ["\ things everywhere. <ul class="simple_navigation" depth="0" id="simple_navigation_default"> ["<li class=\"menu\" drop_down=\"true\" id=\"simple_navigation_default_menus_home\"><a href=\"/home\">Wellcome</a><ul depth=\"1\" id=\"simple_navigation_default_menus_home_menus\"> [\"<li class=\\\"menu\\\" drop_down=\\\"false\\\" id=\\\"simple_navigation_default_menus_home_menus_settings\\\"><a href=\\\"/home/settings\\\">Appliction Settings</a></li>\"] </ul> </li>"] What am I doing wrong? Is there a way to tell Ruby on rails to NOT escape html?

  • How to Redirect Visual Studio F12 Shortcut Key to Object Browser in C# Project

    - by AMissico
    For C# projects, I would like to have the F12 "Go to Definition" shortcut key to open the Object Browser and select the type under the cursor position. This is the behavior for VB.NET projects, which I really like. I think the Object Browser is more helpful than IntelliSense in some cases. I really do not need a text representation of the metadata. How do I duplicate the F12 / "Go to Definition" functionality in a C# project? Is there a different shortcut key for C#? I am not talking about the Alt+Ctrl+J shortcut key that displays the Object Browser.

  • Posting XML via curl (command-line) without using key/value pairs

    - by Mathias Bynens
    Consider a PHP script that outputs all POST data, as follows: <?php var_dump($_POST); ?> The script is located at http://example.com/foo.php. Now, I want to post XML data to it (without using key/value pairs) using command line curl. I have tried many variations of the following: curl -H "Content-type: text/xml; charset=utf-8" --data-urlencode "<foo><bar>bazinga</foo></bar>" http://example.com/foo.php Yet none of them seem to actually post anything — according to the PHP script, $_POST is just an empty array. What am I doing wrong here?

  • Python Tkinter - Edit external object within event handler?

    - by M3RPHY
    Hey all, As the title says, I'm grabbing the cursor location within a motion triggered event handler in Tkinter. I'd like to update an existing label widget with the location, however I cannot for the life of me figure out how to edit the label's text field (or any external object for that matter) within the event handler. From what I understand, event is the only argument passed to the handler, which means I can't pass the label object. How do I access objects outside of the handler? Apologize for the noobish question as I'm a C programmer new to Python. Thanks!

  • Regex to replace relative link with root relative link

    - by Kendall Hopkins
    I have a string of text that contains html with all different types of links (relative, absolute, root-relative). I need a regex that can be executed by PHP's preg_replace to replace all relative links with root-relative links, without touching any of the other links. I have the root path already. Replaced links: <tag ... href="path/to_file.ext" ... > ---> <tag ... href="/basepath/path/to_file.ext" ... > Untouched links: <tag ... href="/any/path" ... > <tag ... href="protocol://domain.com/any/path" ... >

  • Vertical-centering and overflow Excel-style in CSS?

    - by Eric Grange
    Is there a way to perform a vertical centering of a variable-sized multi-line content within a fixed-size div, with hidden overflow? The aim would be to reproduce what you can see in Excel cells: when the content fits the container, it should be vertically centered, when it is larger, the parts that overflow should be hidden (and the content still vertically aligned), like in an Excel cell whose neighbours aren't empty. I know how to vertically center using CSS, I know how to hide overflow when the content isn't vertically centered, but I've no idea how to do both at the same time... Is Javascript the only answer? The trick is that CSS positioning approaches don't work with variable-sized content (my content is dynamic text), and when you use display:table-cell, it effectively disables CSS overflow control (and the container grows to accomodate the content).

When the secure option is set to NO, I have no problem using all of the international keyboards on my device, but when it is set to YES, I am only able to use the English keyboard. Is there a way to an option I can use to enable this feature, or would I have to do this manually (don't mark the secure option and replace the text the user enters with *'s)? Thanks,

I have one doubt as my keys are (folder/1.txt, folder/2.txt ) may be that's why?

  • Can't get NSDate to work correctly

    - by John
    Hello, having a strange issue, must be something I'm just not seeing. I set up a variable in the .h NSDate *checkIn; @property (nonatomic, retain) NSDate *checkIn; I'm setting a variable to todays date in the initWithNibName: checkIn = [NSDate date]; I also did synthesized it as well. Now later on in my program I use it to build a tablecell with the following line cell.textLabel.text = [dateFormatter stringFromDate:checkIn]; This line kills the simulator, BAD_EXEC. If I put in a checkIn = [NSDate date]; above it, it works fine. So I'm thinking the variable isn't being stored from when I set it in the initWithNibName: Not sure why though, as my strings I do the same way are all working fine from method to method. What am I missing?
