  • Key Tips in WPF

    - by Brad Leach
    Office 2007 and the Ribbon introduced the concept of "Key Tips". In short, every single command in the Ribbon receives a letter which you can press to activate that command. ... The letters are indicated by small "KeyTips" which indicate the letter to press to activate the control. KeyTips are displayed using the Alt key, so using them feels similar to how menu navigation works in Windows. (Source: http://blogs.msdn.com/jensenh/archive/2006/04/12/574930.aspx) An example of the Key Tips can be shown as follows. In this diagram, the use has pressed the ALT key, and is awaiting further input. Are there any WPF Open Source examples of "Key Tips"? How would you go about implementing something like this feature in a generic way (i.e. not requiring a Ribbon)? How would you implement this using a MVVM pattern (given that ICommand does not support InputBindings). Note: ActiPro have implemented this feature in their implementation of a Ribbon, but they have not released source code.

  • Algorithm possible amounts (over)paid for a specific price, based on denominations

    - by Wrikken
    In a current project, people can order goods delivered to their door and choose 'pay on delivery' as a payment option. To make sure the delivery guy has enough change customers are asked to input the amount they will pay (e.g. delivery is 48,13, they will pay with 60,- (3*20,-)). Now, if it were up to me I'd make it a free field, but apparantly higher-ups have decided is should be a selection based on available denominations, without giving amounts that would result in a set of denominations which could be smaller. Example: denominations = [1,2,5,10,20,50] price = 78.12 possibilities: 79 (multitude of options), 80 (e.g. 4*20) 90 (e.g. 50+2*20) 100 (2*50) It's international, so the denominations could change, and the algorithm should be based on that list. The closest I have come which seems to work is this: for all denominations in reversed order (large=>small) add ceil(price/denomination) * denomination to possibles baseprice = floor(price/denomination) * denomination; for all smaller denominations as subdenomination in reversed order add baseprice + (ceil((price - baseprice) / subdenomination) * subdenomination) to possibles end for end for remove doubles sort Is seems to work, but this has emerged after wildly trying all kinds of compact algorithms, and I cannot defend why it works, which could lead to some edge-case / new countries getting wrong options, and it does generate some serious amounts of doubles. As this is probably not a new problem, and Google et al. could not provide me with an answer save for loads of pages calculating how to make exact change, I thought I'd ask SO: have you solved this problem before? Which algorithm? Any proof it will always work?

  • Preserving SCRIPT tags (and more) in CKEditor

    - by Jonathan Sampson
    Update: I'm thinking the solution to this problem is in CKEDITOR.config.protectedSource(), but my regular-expression experience is proving to be too juvenile to handle this issue. How would I go about exempting all tags that contain the 'preserved' class from being touched by CKEditor? Is it possible to create a block of code within the CKEditor that will not be touched by the editor itself, and will be maintained in its intended-state until explicitly changed by the user? I've been attempting to input javascript variables (bound in script tags) and a flash movie following, but CKEditor continues to rewrite my pasted code/markup, and in doing so breaking my code. I'm working with the following setup: <script type="text/javascript"> var editor = CKEDITOR.replace("content", { height : "500px", width : "680px", resize_maxWidth : "680px", resize_minWidth : "680px", toolbar : [ ['Source','-','Save','Preview'], ['Cut','Copy','Paste','PasteText','PasteFromWord','-','Print', 'SpellChecker', 'Scayt'], ['Undo','Redo','-','Find','Replace','-','SelectAll','RemoveFormat'], ['Bold','Italic','Underline','Strike','-','Subscript','Superscript'], ['NumberedList','BulletedList','-','Outdent','Indent','Blockquote'], ['JustifyLeft','JustifyCenter','JustifyRight','JustifyBlock'], ['Link','Unlink','Anchor'], ['Image','Table','HorizontalRule','SpecialChar'] ] }); CKFinder.SetupCKEditor( editor, "<?php print url::base(); ?>assets/ckfinder" ); </script> UPDATE: I suppose the most ideal solution would be to preserve the contents of any tag that contains class="preserve" enabling much more than the limited exclusives.

  • jQuery UI datepicker will not display - full code included

    - by Bill Brasky
    I am having trouble displaying the jQuery datepicker as shown here: http://jqueryui.com/demos/datepicker/ I believe I downloaded all of the proper files, but to be certain, I started from scratch and ripped the demo site. Not all of it, but what I believed to be the important parts. The result is no datepicker to be shown and no javascript errors. Here is my full code sample: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <link rel="stylesheet" href="http://static.jquery.com/ui/css/base2.css" type="text/css" media="all" /> <link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.1/themes/base/jquery-ui.css" type="text/css" media="all" /> <link rel="stylesheet" href="http://static.jquery.com/ui/css/demo-docs-theme/ui.theme.css" type="text/css" media="all" /> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.min.js"></script> <script type="text/javascript" charset="utf-8" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.1/jquery-ui.min.js"></script> <script type="text/javascript" charset="utf-8"> jQuery(function(){ jQuery("#datepicker").datepicker(); }); </script> </head> <body> <input type="text" id="datepicker" class="hasDatepicker" /> </body> </html> Any help would be very much appreciated.

  • Setting MinimumSize Attribute for a Control in a TFS WorkItem

    - by Jay Yother
    Tools used: Visual Studio 2008 SP1 Team Explorer Team Foundation Server Power Tools October 2008 Release. Using the Process Editor in Visual Studio, I am attempting to set the MinimumSize attribute for a control in a WorkItem template to make the default size of the input area larger. I am setting the attribute according to this website: http://msmvps.com/blogs/vstsblog/archive/2007/07/07/undocumented-attributes-for-controlling-the-work-item-form-layout.aspx No matter what I set this attribute to it has no affect. I have tried setting the attribute with and without surrounding (). I've tried different capitalization of the attribute but no luck. I have verified that the MinimumSize attribute is being correctly set in the associated xml file. The control (HtmlFieldControl) is currently setup as the second child on a Tab Page. (The first control is also an HtmlFieldControl.) I've tried adding a group to the Tab Page such that the hierarchy is TabPage-Group-Column-Control with no success. I've also tried setting the attribute for the first control with no luck. Any idea what I am doing wrong?

  • Render multiple control collections in ASP.NET custom control

    - by Monty
    I've build a custom WebControl, which has the following structure: <gws:ModalBox ID="ModalBox1" HeaderText="Title" runat="server"> <Contents>(controls...)</Contents> <Footer>(controls...)</Footer> </gws:ModalBox> The control contains two ControlCollection properties, 'Contents' and 'Footer'. Never tried to build a control with multiple control collections, but solved it like this (simplified): [PersistChildren(false), ParseChildren(true)] public class ModalBox : WebControl { private ControlCollection _contents; private ControlCollection _footer; public ModalBox() : base() { this._contents = base.CreateControlCollection(); this._footer = base.CreateControlCollection(); } [PersistenceMode(PersistenceMode.InnerProperty)] public ControlCollection Contents { get { return this._contents; } } [PersistenceMode(PersistenceMode.InnerProperty)] public ControlCollection Footer { get { return this._footer; } } protected override void RenderContents(HtmlTextWriter output) { // Render content controls. foreach (Control control in this.Contents) { control.RenderControl(output); } // Render footer controls. foreach (Control control in this.Footer) { control.RenderControl(output); } } } However it seems to render properly, it doesn't work anymore if I add some asp.net labels and input controls inside the property. I'll get the HttpException: Unable to find control with id 'KeywordTextBox' that is associated with the Label 'KeywordLabel'. Somewhat understandable, because the label appears before the textbox in the controlcollection. However, with default asp.net controls it does work, so why doesn't this work? What am I doing wrong? Is it even possible to have two control collections in one control? Should I render it differently? Thanks for replies.

  • BackgroundWorker might be causing my application to hang

    - by alexD
    I have a Form that uses a BackgroundWorker to execute a series of tests. I use the ProgressChanged event to send messages to the main thread, which then does all of the updates on the UI. I've combed through my code to make sure I'm not doing anything to the UI in the background worker. There are no while loops in my code and the BackgroundWorker has a finite execution time (measured in seconds or minutes). However, for some reason when I lock my computer, often times the application will be hung when I log back in. The thing is, the BackgroundWorker isn't even running when this happens. The reason I believe it is related to the BackgroundWorker though is because the form only hangs when the BackgroundWorker has been executed since the application was loaded (it only runs when given a certain user input). I pass this thread a List of TreeNodes from a TreeView in my UI through the RunWorkerAsync method, but I only read those nodes in the worker thread..any modifications I make to them is done in the UI thread through the progressChanged event. I do use Thread.Sleep in my worker thread to execute tests at timed intervals (which involves sending messages over a TCP socket, which was not created in the worker thread). I am completely perplexed as to why my application might be hanging. I'm sure I'm doing something 'illegal' somewhere, I just don't know what.

  • Invert a string: Recursion vs iteration in javascript

    - by steweb
    Hi all, one month ago I've been interviewed by some google PTO members. One of the questions was: Invert a string recursively in js and explain the running time by big O notation this was my solution: function invert(s){ return (s.length > 1) ? s.charAt(s.length-1)+invert(s.substring(0,s.length-1)) : s; } Pretty simple, I think. And, about the big-o notation, I quickly answered O(n) as the running time depends linearly on the input. - Silence - and then, he asked me, what are the differences in terms of running time if you implement it by iteration? I replied that sometimes the compiler "translate" the recursion into iteration (some programming language course memories) so there are no differences about iteration and recursion in this case. Btw since I had no feedback about this particular question, and the interviewer didn't answer "ok" or "nope", I'd like to know if you maybe agree with me or if you can explain me whether there could be differences about the 2 kind of implementations. Thanks a lot and Regards!

  • Python DictReader - Skipping rows with missing columns?

    - by victorhooi
    heya, I have a Excel .CSV file I'm attempting to read in with DictReader. All seems to be well, except it seems to omit rows, specifically those with missing columns. Our input looks like: mail,givenName,sn,lorem,ipsum,dolor,telephoneNumber [email protected],ian,bay,3424,8403,2535,+65(2)34523534545 [email protected],mike,gibson,3424,8403,2535,+65(2)34523534545 [email protected],ross,martin,,,,+65(2)34523534545 [email protected],david,connor,,,,+65(2)34523534545 [email protected],chris,call,3424,8403,2535,+65(2)34523534545 So some of the rows have missing lorem/ipsum/dolor columns, and it's just a string of commas for those. We're reading it in with: def read_gd_dump(input_file="blah 20100423.csv"): gd_extract = csv.DictReader(open('blah 20100423.csv'), restval='missing', dialect='excel') return dict([(row['something'], row) for row in gd_extract]) And I checked that "something" (the key for our dict) isn't one of the missing columns, I had originally suspected it might be that. It's one of the columns after that. However, DictReader seems to completely skip over the rows. I tried setting restval to something, didn't seem to make any difference. I can't seem to find anything in Python's CSV docs (http://docs.python.org/library/csv.html) that would explain this behaviour, but I may have misread something. Any ideas? Thanks, Victor

  • maven-release-plugin: Perform fails with 'working directory "...workspace\target\checkout\workspace"

    - by Ed
    Hi, I have maven project that fails when release:perform is called, though release;prepare works as expected. I have found the bug report (below) which certainly seems to resemble the issue I have but not entirely sure I understand the problem: MRELEASE516 The last few lines of output I get: [INFO] Executing: cmd.exe /X /C "p4 -d E:\hudson\jobs\myHudsonJob\workspace\target\checkout -p 10.20.0.38:1666 client -d myProjectWorkspace-MavenSCM-E:\hudson\jobs\myHudsonJob\workspace\target\checkout" [INFO] Executing goals 'deploy'... [WARNING] Base directory is a file. Using base directory as POM location. [WARNING] Maven will be executed in interactive mode, but no input stream has been configured for this MavenInvoker instance. [INFO] ------------------------------------------------------------------------ [ERROR] BUILD ERROR [INFO] ------------------------------------------------------------------------ [INFO] Error executing Maven. Working directory "E:\hudson\jobs\myHudsonJob\workspace\target\checkout\workspace" does not exist! From reading the bug report the possible cause of the error is related to my modules' structure, I've tried to outline it below: /workspace | |+ pom.xml (root pom whose parent is the build pom, | calling release:perform on this pom) | [Modules: moduleA and moduleB] | |- moduleA |+ pom.xml (parent is also build pom) |+ build/pom.xml (the build pom - no custom parent) |- moduleB |+ pom.xml (parent is build pom) It seems that the root pom should be in some common directory inside 'workspace' from the error but tried that and doesn't work, nor make sense as to why I need it. What does the warning Base directory is a file want me to do instead?! It then figures that the base directory is workspace which then means the working directory is not found...any ideas? Thanks in advance.

  • In WMI, can I use a join (or something similar) to acquire the IisWebServer object for a site, given

    - by Precipitous
    Given a server name and a physical path, I'd like to be able to hunt down the IISWebServer object and ApplicationPool. Website url is also an acceptable input. Our technologies are IIS 6, WMI, and access via C# or Powershell 2. I'm certain this would be easier with IIS 7 its managed API. We don't have that yet. Here's what I can do: Get a list of IIS virtual directories from IISWebVirtualDirSetting and filter (offline) for the matching physical path. $theVirtualDir = gwmi -Namespace "root/MicrosoftIISv2" ` -ComputerName $servername -authentication PacketPrivacy ` -class "IISWebVirtualDirSetting" ` | where-object {$_.Path -like $deployLocation} From the virtual directory object, I can get a name (like W3SVC/40565456/root). Given this name, I can get to other goodies, such as the IIS web server object. gwmi -Namespace "root/MicrosoftIISv2" ` -ComputerName $servername ` -authentication PacketPrivacy ` -Query "SELECT * FROM IisWebServer WHERE Name='W3SVC/40589473'" The questions, restated: 1) This is a query language. Can I join or subquery so that 1 WMI query statement gets web servers based on IISWebVirtualDir.Path? How? 2) In solving 1, you'll have to explain how to query on the Path property. Why is this an invalid query? "SELECT * FROM IISWebVirtualDirSetting WHERE Path='D:\sites\globaldominator'"

  • Finding a picture in a picture with java?

    - by tarrasch
    what i want to to is analyse input from screen in form of pictures. I want to be able to identify a part of an image in a bigger image and get its coordinates within the bigger picture. Example: would have to be located in And the result would be the upper right corner of the picture in the big picture and the lower left of the part in the big picture. As you can see, the white part of the picture is irrelevant, what i basically need is just the green frame. Is there a library that can do something like this for me? Runtime is not really an issue. What i want to do with this is just generating a few random pixel coordinates and recognize the color in the big picture at that position, to recognize the green box fast later. And how would it decrease performance, if the white box in the middle is transparent? The question has been asked several times on SO as it seems without a single answer. I found i found a solution at http://werner.yellowcouch.org/Papers/subimg/index.html . Unfortunately its in C++ and i do not understand a thing. Would be nice to have a Java implementation on SO.

  • DSP - Filtering frequencies using DFT

    - by Trap
    I'm trying to implement a DFT-based 8-band equalizer for the sole purpose of learning. To prove that my DFT implementation works I fed an audio signal, analyzed it and then resynthesized it again with no modifications made to the frequency spectrum. So far so good. I'm using the so-called 'standard way of calculating the DFT' which is by correlation. This method calculates the real and imaginary parts both N/2 + 1 samples in length. To attenuate a frequency I'm just doing: float atnFactor = 0.6; Re[k] *= atnFactor; Im[k] *= atnFactor; where 'k' is an index in the range 0 to N/2, but what I get after resynthesis is a slighty distorted signal, especially at low frequencies. The input signal sample rate is 44.1 khz and since I just want a 8-band equalizer I'm feeding the DFT 16 samples at a time so I have 8 frequency bins to play with. Can someone show me what I'm doing wrong? I tried to find info on this subject on the internet but couldn't find any. Thanks in advance.

  • User authentication using CodeIgniter

    - by marcin_koss
    I have a problem creating authentication part for my application. Below is the simplified version of my controllers. The idea is that the MY_controller checks if session with user data exists. If it doesn’t, then redirects to the index page where you have to log in. MY_controller.php class MY_Controller extends Controller { function __construct() { parent::__construct(); $this->load->helper('url'); $this->load->library('session'); if($this->session->userdata('user') == FALSE) { redirect('index'); } else { redirect('search'); } } } order.php - main controller class Orders extends MY_Controller { function __construct() { parent::__construct(); $this->load->helper('url'); $this->load->library('session'); } function index() { // Here would be the code that validates information input by user. // If validation is successful, it creates user session. $this->load->view('header.html', $data); // load header $this->load->view('index_view', $data); // load body $this->load->view('footer.html', $data); // load footer } function search() { //different page } what is happening is that the browser is telling me that “The page isn’t redirecting properly. Firefox has detected that the server is redirecting the request for this address in a way that will never complete.” It seems like the redirect() is being looped. I looked at a few other examples of user auth and they were build using similar technique.

  • Codeplex/Sourceforge for internal use

    - by Josh
    I'm looking for a free/open source collaborative project manager that can be deployed internally in my workplace that would act similar to Codeplex or Sourceforge. Does anyone know of something like this, and if so do you have experience with it. Requirements: Open Source or Free Locally Deployable Has the same types of features found in Sourceforge / Codeplex Issue/Feature Tracking Community Interaction (ie. Voting, Roles, etc.) SCM Integration (Optional) .NET/Windows Friendly (Optional) Every business ends up having internal utilities, and domain specific apps that developers create to make life easier. Given the input of the internal developer community they have the potential to become much better (can you say GMail...), and I would simply like to foster such an environment internally by providing an easy place for that interaction to take place. UPDATE: So I like what I am seeing in both Trac and GForge, but both are heavily geared towards UNIX/Subversion environments. I should have specified this, but we are a MS shop from top to bottom. How practical do you think it is going to be to try and use these in a MS .NET environment? Would that be like trying to shove a square peg through a round hole?

  • CodeGolf: Find the Unique Paths

    - by st0le
    Here's a pretty simple idea, in this pastebin I've posted some pair of numbers. These represent Nodes of a directed graph. The input to stdin will be of the form, (they'll be numbers, i'll be using an example here) c d q r a b b c d e p q so x y means x is connected to y (not viceversa) There are 2 paths in that example. a->b->c->d->e and p->q->r. You need to print all the unique paths from that graph The output should be of the format a->b->c->d->e p->q->r Notes You can assume the numbers are chosen such that one path doesn't intersect the other (one node belongs to one path) The pairs are in random order. They are more than 1 paths, they can be of different lengths. All numbers are less than 1000. If you need more details, please leave a comment. I'll amend as required. Shameless-Plug For those who enjoy Codegolf, please Commit at Area51 for its very own site:) (for those who don't enjoy it, please support it as well, so we'll stay out of your way...)

  • Generating JavaScript in C# and subsequent testing

    - by Codebrain
    We are currently developing an ASP.NET MVC application which makes heavy use of attribute-based metadata to drive the generation of JavaScript. Below is a sample of the type of methods we are writing: function string GetJavascript<T>(string javascriptPresentationFunctionName, string inputId, T model) { return @"function updateFormInputs(value){ $('#" + inputId + @"_SelectedItemState').val(value); $('#" + inputId + @"_Presentation').val(value); } function clearInputs(){ " + helper.ClearHiddenInputs<T>(model) + @" updateFormInputs(''); } function handleJson(json){ clearInputs(); " + helper.UpdateHiddenInputsWithJson<T>("json", model) + @" updateFormInputs(" + javascriptPresentationFunctionName + @"()); " + model.GetCallBackFunctionForJavascript("json") + @" }"; } This method generates some boilerplace and hands off to various other methods which return strings. The whole lot is then returned as a string and written to the output. The question(s) I have are: 1) Is there a nicer way to do this other than using large string blocks? We've considered using a StringBuilder or the Response Stream but it seems quite 'noisy'. Using string.format starts to become difficult to comprehend. 2) How would you go about unit testing this code? It seems a little amateur just doing a string comparison looking for particular output in the string. 3) What about actually testing the eventual JavaScript output? Thanks for your input!

    here is a part of html code (video urls marked with a django-template language variables): <div class="mainPlayer"> <object width="580" height="326"> <param name="movie" value="{{main_video.video_url}}"></param> <param name="allowFullScreen" value="true"></param> <param name="allowscriptaccess" value="always"></param> <embed src="{{main_video.video_url}}" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="580" height="326"></embed> </object> </div> and JS-code (using jQuery 1.4.x) $(document).ready(function(){ ..... $(".activeMovie img").live("click", function(){ video_url = ($(this).parent().find('input').val()); $('.mainPlayer').find('param:eq(0)').val(video_url); $('.mainPlayer').find('embed').attr('src', video_url); }) ... }) such a algorithm works fine in ff 3.6.3, but any luck in chrome4 or opera 10.x., src and value are changed, but youtube player still shows an old video.

  • Oracle - Getting Select Count(*) from ... as an output parameter in System.Data.OracleClient

    - by cbeuker
    Greetings all, I have a question. I am trying to build a parametrized query to get me the number of rows from a table in Oracle. Rather simple. However I am an Oracle newbie.. I know in SQL Server you can do something like: Select @outputVariable = count(*) from sometable where name = @SomeOtherVariable and then you can set up an Output parameter in the System.Data.SqlClient to get the @outputVariable. Thinking that one should be able to do this in Oracle as well, I have the following query Select count(*) into :theCount from sometable where name = :SomeValue I set up my oracle parameters (using System.Data.OracleClient - yes I know it will be deprecated in .Net 4 - but that's what I am working with for now) as follows IDbCommand command = new OracleCommand(); command.CommandText = "Select count(*) into :theCount from sometable where name = :SomeValue"); command.CommandType = CommandType.Text; OracleParameter parameterTheCount = new OracleParameter(":theCount ", OracleType.Number); parameterTheCount .Direction = ParameterDirection.Output; command.Parameters.Add(parameterTheCount ); OracleParameter parameterSomeValue = new OracleParameter(":SomeValue", OracleType.VarChar, 40); parameterSomeValue .Direction = ParameterDirection.Input; parameterSomeValue .Value = "TheValueToLookFor"; command.Parameters.Add(parameterSomeValue ); command.Connection = myconnectionObject; command.ExecuteNonQuery(); int theCount = (int)parameterTheCount.Value; At which point I was hoping the count would be in the parameter parameterTheCount that I could readily access. I keep getting the error ora-01036 which http://ora-01036.ora-code.com tells me to check my binding in the sql statement. Am I messing something up in the SQL statement? Am I missing something simple elsewhere? I could just use command.ExecuteScaler() as I am only getting one item, and am probably going to end up using that, but at this point, curiosity has got the better of me. What if I had two parameters I wanted back from my query (ie: select max(ColA), min(ColB) into :max, :min.....) Thanks..

  • Excel VBA Macro for Pivot Table with Dynamic Data Range

    - by John Ziebro
    CODE IS WORKING! THANKS FOR THE HELP! I am attempting to create a dynamic pivot table that will work on data that varies in the number of rows. Currently, I have 28,300 rows, but this may change daily. Example of data format as follows: Case Number Branch Driver 1342 NYC Bob 4532 PHL Jim 7391 CIN John 8251 SAN John 7211 SAN Mary 9121 CLE John 7424 CIN John Example of finished table: Driver NYC PHL CIN SAN CLE Bob 1 0 0 0 0 Jim 0 1 0 0 0 John 0 0 2 1 1 Mary 0 0 0 1 0 Code as follows: Sub CreateSummaryReportUsingPivot() ' Use a Pivot Table to create a static summary report ' with model going down the rows and regions across Dim WSD As Worksheet Dim PTCache As PivotCache Dim PT As PivotTable Dim PRange As Range Dim FinalRow As Long Dim FinalCol As Long Set WSD = Worksheets("PivotTable") 'Name active worksheet as "PivotTable" ActiveSheet.Name = "PivotTable" ' Delete any prior pivot tables For Each PT In WSD.PivotTables PT.TableRange2.Clear Next PT ' Define input area and set up a Pivot Cache FinalRow = WSD.Cells(Application.Rows.Count, 1).End(xlUp).Row FinalCol = WSD.Cells(1, Application.Columns.Count). _ End(xlToLeft).Column Set PRange = WSD.Cells(1, 1).Resize(FinalRow, FinalCol) Set PTCache = ActiveWorkbook.PivotCaches.Add(SourceType:= _ xlDatabase, SourceData:=PRange) ' Create the Pivot Table from the Pivot Cache Set PT = PTCache.CreatePivotTable(TableDestination:=WSD. _ Cells(2, FinalCol + 2), TableName:="PivotTable1") ' Turn off updating while building the table PT.ManualUpdate = True ' Set up the row fields PT.AddFields RowFields:="Driver", ColumnFields:="Branch" ' Set up the data fields With PT.PivotFields("Case Number") .Orientation = xlDataField .Function = xlCount .Position = 1 End With With PT .ColumnGrand = False .RowGrand = False .NullString = "0" End With ' Calc the pivot table PT.ManualUpdate = False PT.ManualUpdate = True End Sub

  • 2 Mutually exclusive RadioButton "Lists"

    - by user72603
    I think this has to be THE most frustrating thing I've ever done in web forms. Yet one would think it would be the easiest of all things in the world to do. That is this: I need 2 separate lists of radiobuttons on my .aspx page. One set allows a customer to select an option. The other set does also but for a different purpose. But only one set can have a selected radiobutton. Ok I've tried this using 2 asp.net Radiobuttonlists controls on the same page. Got around the nasty bug with GroupName (asp.net assigns the control's uniqueID which prevents the groupname from ever working because now, 2 radiobuttonlists can't have the same groupname for all their radiobuttons because each radiobuttonlist has a different uniqueID thus the bug assigns the unique ID as the name attribute when the buttons are rendered. since the name sets are different, they are not mutually exclusive). Anyway, so I created that custom RadioButtonListcontrol and fixed that groupname problem. But when ended up happening is when I went to put 2 instances of my new custom radiobuttonlist control on my .aspx page, all was swell until I noticed that every time I checked for radiobuttonlist1.SelectedValue or radiobuttonlist2.SelectedValue (did not matter which I was checking) the value always spit back string.empty and i was not able to figure out why (see http://forums.asp.net/t/1401117.aspx). Ok onto the third try tonight and into the break of dawn (no sleep). I tried to instead just scrap trying to use 2 custom radiobuttonlists altogether because of that string.empty issue and try to spit out 2 sets of radiobuttonlists via using 2 asp.net repeaters and a standard input HTML tag inside. Got that working. Ok but the 2 lists still are not mutually exclusive. I can select a value in the first set of radiobuttons from repeater1 and same goes for repeater2. I cannot for the life of me get the "sets" to be mutually exclusive sets of radiobuttons.
