• Drawing the call stack in a recursive method

  - by Shaza

  Hey, I want to draw the call stack for any recursive method, so I've created a schema like this, recursiveMethod(){ //Break recursion condition if(){ // Add value here to the return values' list- No drawing return } else{ //Draw stack with the value which will be pushed to the stack here variable <- recursiveMethod() //Clear the drawing which represents the poped value from the stack here return variable }} Notes: This schema can draw recursive methods with n recursive call by making the recursive calls in a separate return statements. returnValues list, is a list which save all the return values, just for viewing issues. What do you think of this? any suggestions are extremely welcomed.

• SelectedValue which is invalid because it does not exist in the list of items

  - by Bob Jones

  I encounter this problem repeatedly, and haven't a clue what is causing it. I get an exception in the DataBind: "SelectedValue which is invalid because it does not exist in the list of items". Here are some important pieces of information: 1) I reload listOrgs periodically when the underlying data has changed. 2) The Organization.DTListAll call returns about 500 Int, String pairs. 3) There are no duplicate or null values in the returned data 4) After the first two lines below, listOrgs.Items.Count is 0, and the Selected Value is 0 5) The selected value when the DataBind operation executes is a value that is not in the set of ID values returned 6) All of the stuff I have found on line so far hasn't helped. 7) I am stumped! listOrgs.Items.Clear(); listOrgs.SelectedValue = "0"; listOrgs.DataSource = new Organization().DTListAll(SiteID); listOrgs.DataTextField = "OrganizationName"; listOrgs.DataValueField = "OrganizationID"; listOrgs.DataBind(); Bob Jones

• Re-Apply currency formatting to a UITextField on a change event

  - by Jim Aldes

  Howdy all, I'm working with a UITextField that holds a localized currency value. I've seen lots of posts on how to work with this, but my question is: how do I re-apply currency formatting to the UITextField after every key press? I know that I can set up and use a currency formatter with: NSNumberFormatter *currencyFormatter = [[NSNumberFormatter alloc] init]; [currencyFormatter setNumberStyle:NSNumberFormatterCurrencyStyle]; ... [currencyFormatter stringFromNumber:...]; but I don't know how to hook it up. For instance, if the value in the field reads "$12,345" and the user taps the "6" key, then the value should change to "$123,456". Which callback is the "correct" one to do this in (should I use textField:shouldChangeCharactersInRange:replacementString: or a custom target-action) and how do I use the NSNumberFormatter to parse and re-apply formatting to the UITextField's text property? Any help would be much appreciated! Thanks!

• How to determine whether a dependency object implements a given dependency property (C# / WPF)

  - by Tim Coulter

  I am working with the classes in the System.Windows.Documents namespace, trying to write some generic code that will conditionally set the value of certain dependency properties, depending on whether these properties exist on a given class. For example, the following method assigns an arbitrary value to the Padding property of the passed FrameworkContentElement: void SetElementPadding(FrameworkContentElement element) { element.SetValue(Block.PaddingProperty, new Thickness(155d)); } However, not all concrete implementations of FrameworkContentElement have a Padding property (Paragraph does but Span does not) so I would expect the property assignment to succeed for types that implement this property and to be silently ignored for types that do not. But it seems that the above property assignment succeeds for instances of all derivatives of FrameworkContentElement, regardless of whether they implement the Padding property. I make this assumption because I have always been able to read back the assigned value. I assume there is some flaw in the way I am assigning property values. What should I do to ensure that a given dependency property assignment is ignored by classes that do not implement that property? Many thanks for your advice. Tim

• Posting a textarea form with cURL

  How would I go about posting a textarea form? <form method="post" action="/user/test/shoutbox/add" id="shoutPost" class="clearit"> <input name="formtoken" type="hidden" value="852f8fde54190fa5f9aa47172d492f829c1b"/> <input type="hidden" name="backto" value="/user/text/shoutbox" /> <textarea id="shoutmsg" name="message"></textarea> <input type="submit" name="submit" class="confirmButton" value="Post" id="sbPost" /> This should work right? curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($ch, CURLOPT_POST, 1); $postfields .= "&message=".$msg; $postfields .= "&submit=sbPost"; curl_setopt($ch, CURLOPT_POSTFIELDS,$postfields); curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1); $page = curl_exec($ch); but it's not posting for some reason...

• Get drive label in C#

  - by Rick

  When I use System.IO.DriveInfo.GetDrives() and look at the .VolumeLabel property of one of the drives, I see "PATRIOT XT", which is indeed the drive's volume label. If I open "My Computer", instead I see "TrueCrypt Traveler Disk", and I can't seem to find any way to programmatically retrieve that value as none of the DriveInfo properties hold that value. I also tried querying the information via WMI's Win32_LogicalDisk, but no properties contained that value there either. So any idea what the label My Computer uses is called, and more importantly, how to programmatically retrieve it? Thanks

• Clear default values using onsubmit

  - by Thomas

  I need to clear the default values from input fields using js, but all of my attempts so far have failed to target and clear the fields. I was hoping to use onSubmit to excute a function to clear all default values (if the user has not changed them) before the form is submitted. <form method='get' class='custom_search widget custom_search_custom_fields__search' onSubmit='clearDefaults' action='http://www.example.com' > <input name='cs-Price-2' id='cs-Price-2' class='short_form' value='Min. Price' /> <input name='cs-Price-3' id='cs-Price-3' class='short_form' value='Max Price' /> <input type='submit' name='search' class='formbutton' value=''/> </form> How would you accomplish this?

• MySQL Trigger creation

  - by Bruce Garlock

  I have an application where I need to INSERT an auto_increment value from a PK in another table. I know how to do this in PHP, but I need to have this done at the DB level, since I cannot change the program logic. I am new to triggers, so I'm sure this will be an easy answer for someone. Here is what I have so far: DELIMITER // CREATE TRIGGER new_project AFTER INSERT ON m_quality_header FOR EACH ROW BEGIN INSERT INTO m_quality_detail (d_matl_qa_ID) VALUES (NEW.h_matl_qa_ID); END// DELIMITER ; I just want the value of the auto_increment value from h_matl_qa_ID to be inserted as a new record into d_matl_qa_ID. The error I get is: "This version of MySQL doesn't yet support 'multiple triggers with the same action time and event for one table' But, I don't want to update the table that has the trigger, so why is my current code considered a 'multiple' trigger? This is on MySQL 5.0.45-7.el5 running on a CentOS 5 server (64-bit Intel) If I have to, I can modify the PHP code, but that needs to be the last resort.

• php selecting hash using wildcards

  - by tipu

  Say I have a hashmap, $hash = array('fox' => 'some value', 'fort' => 'some value 2', 'fork' => 'some value again); I am trying to accomplish an autocomplete feature. When the user types 'fo', I would like to retrieve, via ajax, the 3 keys from $hash. When the user types 'for', I would like to only retrieve the keys fort and fork. Is this possible? What I was thinking was using binary search to isolate the keys with 'f', instead of brute-force searching. Then continue eliminating the indexes as the user types out their query. Is there a more efficient solution to this?

• A very weird problem with texbox control in C# .net

  - by Kazoom

  Well i know textbox is a very simple user control, perhaps the first input control ever made. I have been facing a very frustrating problem with this simple control. I programatically add a textbox in my user control. From ui i am able to edit it like a normal textbox. however, i am not able to read the user inputed value in the program. my program all the time sees the old value with which my text box was initialized. i textchange event getting triggered but the value never gets updated. This seemingly looks to be some innocuous bug in the code, but the program is very simple and it does not seem to be having any bug. Any guidelines on this issue?

• LLBLGen: Copy table from one database to another

  - by StreamT

  I have two databases (SQL Server 2005) with the same table schemes. I need to copy data from source table to destination with some modification of data along the way. And if destination table already contains some data, then rows from source table should not override, but be added to the destination table. In our project we use LLBLGen and LINQ to LLBLGen to as ORM solution. Example: Table 1: Table 2: Table 1: Key Value Key Value Key Value 1 One 1 T2_One Result=> 1 One 2 Two 2 T2_Two 2 Two 3 Three 3 Three 4 T2_One 5 T2_Two

• How does MTOM work + sample code

  - by zengr

  I am trying to make a very simple web-service which does the following: The client hits the web service requesting a file. The web service's service class queries a hashtable which has the key (search query) and the value as the base64encoded value of a file (say a pdf) Now,I need to use MTOM to return the base64encoded value stored in the hashtable to the client. It's upto the client to decode it and convert it to pdf. So, here are my questions: I understand we encode files to base64 for transmission via web service, but where and how does MTOM come into the picture there? Can some one provide me a simple method which uses MTOM and sends the data back. Do we need to specify something in the WSDL too? or a simple String return type would suffice? Why/Why not? Thanks I have seen this code. It uses a lot of annotations, I just need a simple java code using MTOM. New to J2EE HERE :)

• jQuery UI Slider - Animation of handle and scroll content not in sync

  - by Mayko

  Im having troubles getting the jQuery UI Slider customized for my purposes. On load the slider and its content should automatically animate to a certain position. Ideally it should animate to the very right, then stop and then animate back (as a loop) as long as the user doesn't hovers over scroll content or slider. Following my default slider setup (http://jsfiddle.net/mayko/j6WuE/1/): var scrollbar = $("#slider").slider({ animate: 3000, min: 0, max: $("#timeline_content .items").width(), change: handleSlider, slide: handleSlider }); function handleSlider(e, ui) { $("#timeline_content").stop().animate({scrollLeft: ui.value}, scrollbar.slider("option", "animate")); } If i now try to set the value like this: $('#slider').slider({'value': 1000}); The scroll content nicely animates, but the handle just jumps to that new position. Even if I click on the slider track itself the animation of scroll content and slider handle are not in sync. Does anyone got a solution?

• Why don't all System.Web.UI.WebControl classes with Text properties implement ITextControl?

  - by jrummell

  I'm curious why only some System.Web.UI.WebControl controls implement certain interfaces when they have the same properties of an interface. For instance, there are plenty of controls that have a Text property but only the following implement ITextControl: Label Literal DataBoundLiteral TextBox ListControl (TextBox and ListControl actually implement IEditableTextControl which implements ITextControl) TableCell, Button, HyperLink and others don't so I have to write code like this ITextControl textControl = control as ITextControl; TableCell tableCell = control as TableCell; if (textControl != null) { textControl.Text = value; } else if (tableCell != null) { tableCell.Text = value; } instead of this control.Text = value; Was this a design decision or an oversight?

• ASP.NET MVC 2: Custom client side validation rule for dropdowns

  - by Nigel

  I have some custom validation that I need to perform that involves checking the selected option of a dropdown and flagging it as invalid should the user select a specific option. I am using ASP.NET MVC 2 and have a custom Validator and custom server side and client side validation rules as described in this blog article. The server side validation is working fine, however, the client side validation is failing. Here is the javascript validation rule: Sys.Mvc.ValidatorRegistry.validators["badValue"] = function(rule) { var badValue = rule.ValidationParameters["badValue"]; return function(value, context) { if (value != badValue) { return true; } return rule.ErrorMessage; }; }; The rule is being applied to the dropdowns successfully, and placing a breakpoint within the returned function confirms that the validation is firing, and that the 'badValue' is being correctly set. However, 'value' is always null, and so the check always fails. What am I doing wrong?

Once I select the first value in the ComboBox it sets it up. But when I select another value, it doesn't get changed.
