  • WPF MVVM Chart change axes

    - by c0uchm0nster
    I'm new to WPF and MVVM. I'm struggling to determine the best way to change the view of a chart. That is, initially a chart might have the axes: X - ID, Y - Length, and then after the user changes the view (either via lisbox, radiobutton, etc) the chart would display the information: X - Length, Y - ID, and after a third change by the user it might display new content: X - ID, Y - Quality. My initial thought was that the best way to do this would be to change the bindings themselves. But I don't know how tell a control in XAML to bind using a Binding object in the ViewModel, or whether it's safe to change that binding in runtime? Then I thought maybe I could just have a generic Model that has members X and Y and populate them as needed in the viewmodel? My last thought was that I could have 3 different chart controls and just hide and show them as appropriate. What is the CORRECT/SUGGESTED way to do this in the MVVM pattern? Any code examples would be greatly appreciated. Thanks

  • Sub Menu Rollover Pop up Not Showing

    - by Stradigos
    Hello everyone, hopefully this will be an easy answer for some of you CSS veterans out there. I'm developing a site for a client. For readability, I'll just give you a link to the website and the css page in question. HTML CSS I'm trying to make a sub menu pop up to the right of the main menu when you scroll over "Star Quartz Grout." My current CSS obviously isn't correct though, and I could use some guidance. ul#subNav {display: none; width: 134px; } li:hover ul#subNav, li.over ul#subNav {display: inline-block; position: absolute; top: 0px; left: 134px; } My guess is that it's working but it's hidden behind the rest of the page. I could be wrong though. It's kind of hard to confirm, even with Chrome's "Inspect Element" (very nice thing btw). It's probably some dumb mistake. Anyway, thanks in advance. I'm a bit of a CSS novice.

  • python - tkinter - update label from variable

    - by Tom
    I wrote a python script that does some stuff to generate and then keep changing some text stored as a string variable. This works, and I can print the string each time it gets changed. Problems have arisen while trying to display that output in a GUI (just as a basic label) using tkinter. I can get the label to display the string for the first time... but it never updates. This is really the first time I have tried to use tkinter, so it's likely I'm making a foolish error. What I've got looks logical to me, but I'm evidently going wrong somewhere! from tkinter import * outputText = 'Ready' counter = int(0) root = Tk() root.maxsize(400, 400) var = StringVar() l = Label(root, textvariable=var, anchor=NW, justify=LEFT, wraplength=398) l.pack() var.set(outputText) while True: counter = counter + 1 #do some stuff that generates string as variable 'result' outputText = result #do some more stuff that generates new string as variable 'result' outputText = result #do some more stuff that generates new string as variable 'result' outputText = result if counter == 5: break root.mainloop() I also tried: from tkinter import * outputText = 'Ready' counter = int(0) root = Tk() root.maxsize(400, 400) var = StringVar() l = Label(root, textvariable=var, anchor=NW, justify=LEFT, wraplength=398) l.pack() var.set(outputText) while True: counter = counter + 1 #do some stuff that generates string as variable 'result' outputText = result var.set(outputText) #do some more stuff that generates new string as variable 'result' outputText = result var.set(outputText) #do some more stuff that generates new string as variable 'result' outputText = result var.set(outputText) if counter == 5: break root.mainloop() In both cases, the label will show 'Ready' but won't update to change that to the strings as they're generated later. After a fair bit of googling and looking through answers on this site, I thought the solution might be to use update_idletasks - I tried putting that in after each time the variable was changed, but it didn't help. It also seems possible I am meant to be using trace and callback somehow to make all this work...but I can't get my head around how that works (I tried, but didn't manage to make anything that even looked like it would do something, let alone actually worked). I'm still very new to both python and especially tkinter, so, any help much appreciated but please spell it out for me if you can :)

  • Detect if any USB drive is detected or not using WinForm Application in Visual C#

    - by Pavan Kumar
    I want to do the following things in my application 1) I want to display whether any USB drive is inserted or not in my application to prompt the user to insert a USB drive. I just want to notify the user if any USB dirve is inserted else prompt him to insert one using a label or something (i want to avoid messagebox as it will keep appearing whenever a device is inserted or removed. It will be irritating for the end user) in my Visual C# WinForm Application. If any USB drive is present display "USB drive detected" in the label. The user may add one or more USB sticks but the status will remain same. When there is none then the status of the label will change to "No USB drives found.Please insert a USB drive". 2) When one or more USB drive is added the volume name with the drive letter for example "James(F:)" is added to the Combobox list. The combobox list also needs to remove the entry for the USB drive added in the list automatically when it is removed . So when there is no USB the list should be empty and the label will again prompt user to insert a USB stick or drive.

  • Is there such a tool for testing

    - by kjack
    Say one has a structural codebase where lots of the code is in GUI control events and has no tests. So such code, to my knowledge is not suitable for unit testing Is there a tool that can test each routine automatically replacing references to code elements external to the routine (be they functions, variables or GUI controls) with appropriate mocks(?) and record the results in a database for later comparison after code changes? So the testing program would have the duty of writing, running and reporting tests with minimal intervention?

  • Boolean logic parser for SQL

    - by d03boy
    This is going to sound crazy but does anyone have techniques that would allow me to parse boolean logic strings in Sql Server 2005 without extraordinary/rediculous effort? Here is an example: (SOMEVAR=4 OR SOMEVAR=5) AND (NOT OTHERVAR=Y) I feel like recursion would help a lot if that were possible in Sql but I'm not really sure how to go about that sort of thing. If not, maybe there's a way to attach an external system to do the recursion for me? Don't worry, I'm not getting my hopes up.

  • Find a better control

    - by Budda
    It is necessary to implement the following functionality: There is a rectangle "field", its size is 150x100 pixels. Field is split to locations, each location is 10x10 (totally 15x10 locations on the field). There are few "coins" (5, for example), each of them can be dropped into any location. The list of text messages should be displayed in the drop-down list if any coin is clicked (when any message is clicked, drop-down list should be hidden and coin should display the number of selected message from 0 to 9, for example). That should be done with Silverlight 4.0 I am going to implement custom control "Coin", it will have a view (with a circle), it will display some kind of popup-window (please advise, which one), focus will be set to this window. On "FocusLost" window will be closed (without changing message number), if any message from the list will be clicked then its number will be stored inside of coin. Question 1: is there any control that already has required functionality? Question 2: how to implement "drag-and-drop" of coins to the "field" (lets assume, they will be close to the field)? Any thought or ideas will be helpful. Thanks.

  • How to change disclosure style when user enters in edit mode of a UITableView?

    - by R31n4ld0
    Hello, guys. I have a UITableView that in 'normal' mode, show a UITableViewCellAccessoryDisclosureIndicator meaning if the user taps the row, another list is showed, like HIG says: "Disclosure indicator. When this element is present, users know they can tap anywhere in the row to see the next level in the hierarchy or the choices associated with the list item. Use a disclosure indicator in a row when selecting the row results in the display of another list. Don’t use a disclosure indicator to reveal detailed information about the list item; instead, use a detail disclosure button for this purpose." When the user tap the edit button in the top bar of the UITableView, I think I have to change the disclosure because if the user tap it, a view for changing the information of the current row is showed (see the bold line above), again, like HIG says: "Detail disclosure button. Users tap this element to see detailed information about the list item. (Note that you can use this element in views other than table views, to reveal additional details about something; see “Detail Disclosure Buttons” for more information.) In a table view, use a detail disclosure button in a row to display details about the list item. Note that the detail disclosure button, unlike the disclosure indicator, can perform an action that is separate from the selection of the row. For example, in Phone Favorites, tapping the row initiates a call to the contact; tapping the detail disclosure button in the row reveals more information about the contact." Have I miss understood the HIG, or I really do have to change the disclosure style in edit mode of UITableView? If yes, how I can intercept the edit mode when the user taps the Edit button? Thanks in advance.

  • iOS iPad UIActionSheet Issue

    - by hart1994
    I am currently developing an application which needs an option to 'share' using multiple services; such as email, twitter. To to this, I have a UIBarButtonItem coded in and when touched, it triggers this: UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:@"" delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil]; [sheet addButtonWithTitle:@"Email"]; [sheet addButtonWithTitle:@"Tweet"]; [sheet addButtonWithTitle:@"Cancel"]; sheet.cancelButtonIndex = sheet.numberOfButtons-1; [sheet showFromRect:self.view.bounds inView:self.view animated:YES]; [sheet release]; In conjunction with this to detect which button is selected: clickedButtonAtIndex:(NSInteger)buttonIndex { if (buttonIndex == actionSheet.cancelButtonIndex) { return; } switch (buttonIndex) { case 0: { [self emailThis]; break; } case 1: { [self tweetThis]; break; } } This works a treat on the iPhone. But unfortunately it displays incorrectly on the iPad. It looks like it is trying to display the UIPopoverController, but it is positioned center of the navbar with practically no height. I have looked into using the UIPopoverController, but I cannot seem to find out how to use it with buttons. Is there anyway I can adapt the code above to properly display the buttons, as it's trying to already. Many thanks, Ryan PS: I'm new to objective-c/iOS coding, so please be specific. Thank you :)

  • Getting Vars to bind properly across multiple files

    - by Alex Baranosky
    I am just learning Clojure and am having trouble moving my code into different files. I keep detting this error from the appnrunner.clj - Exception in thread "main" java.lang.Exception: Unable to resolve symbol: -run-application in this context It seems to be finding the namespaces fine, but then not seeing the Vars as being bound...

  • WPF ComboBox TemplateBinding to selected value

    - by Greg R
    I'm trying to create an editable textbox via a drop down of selected values. Basically in Red Only mode I want the drop down to be a disabled textbox. It works fine when I do this with SelectedValue but when I need it to display the dropdown text and not the value. This is what I have: <Style x:Key="EditableDropDownValueOnly" TargetType="ComboBox"> <Setter Property="Width" Value="Auto" /> <Setter Property="FontSize" Value="11" /> <Setter Property="HorizontalAlignment" Value="Left" /> <Setter Property="FontFamily" Value="Verdana" /> <Setter Property="MinWidth" Value="25" /> <Style.Triggers> <Trigger Property="IsReadOnly" Value="True"> <Setter Property="Background" Value="#FFFFFF" /> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="ComboBox"> <TextBox Text="{TemplateBinding SelectedItem, Converter={StaticResource StringCaseConverter}}" BorderThickness="0" Background="Transparent" FontSize="{TemplateBinding FontSize}" HorizontalAlignment="{TemplateBinding HorizontalAlignment}" FontFamily="{TemplateBinding FontFamily}" Width="{TemplateBinding Width}" TextWrapping="Wrap"/> </ControlTemplate> </Setter.Value> </Setter> </Trigger> </Style.Triggers> </Style> SelectedItem is a KeyValuePair, since my drop down is bound to a dictionary. I'm trying to display the "Value" element in my template. Is that possible? Thanks a lot!

    I have a XAML file that I exported from Expression Design. I would like to render that XAML content inline in one of my user controls. Can I reference the external XAML file that I want to include as a Resource on the UserControl I want to render it in?

  • Easy way to observe user activity - how improve my database structure.

    - by Thomas
    Welcome, I need some advise to improve perfomence my web application. In the begin I had this structure of database: USER -id (Primary Key) -name -password -email .... PROFILE -user Primary Key, Foreign Key (USER) -birthday -region -photoFile ... PAGES -id (Primary Key) -user Foreign Key(USER) -page -date COMMENTS -id (Primary Key) -user Foreign Key(USER) -page Foreign Key(PAGE) -comment -date FAVOURITES_PAGES -id (Primary Key) -user Foreign Key(USER) -favourite_page Foreign Key(PAGE) -date but now one of the most important page of website is observatory, when everyone can observe activity others users. So I need select all pages, comments and favourites pages some users and display it in one list, sorted by date. For better perfomance (I think) I changed my structure to this: table USER and PROFILE without changes ACTIVITY (additional table- have common fields: user,date) -id (Primary Key) -user Foreign Key(USER) -date -page Foreign Key(PAGE) -comment Foreign Key(COMMENTS) -favourite_page Foreign Key(FAVOURITES_PAGES) PAGES -id (Primary Key) -page COMMENTS -id (Primary Key) -page Foreign Key(PAGE) -comment FAVOURITES_PAGES -id (Primary Key) -favourite_page Foreign Key(PAGE) So now it is very easy get sorted records from all tables. But I have no only foreign key to PAGES, COMMENTS and FAVOURITES_PAGES in ACTIVITY table - there is about ten Foreign Key fields and in one record only one have value, others have None: ACTIVITY id user date page comment ... 1 2 2010-02-23 None 1 2 1 2010-02-21 1 None .... It is corect solution. When I display about 40 records in one page (pagination) I must wait about one secound, but database is almost emty (a few users and about 100 records in others tables). It is depends on amount records per page - I have checked it, but why it takes too long time, becouse of relationships? The website is built in Python/Django. Any advices/opinion?

  • jqModal/JQuery problem, div not updating with new content?

    - by echoesofspring
    I'm hoping someone can point a relative jQuery/jqModal newbie in the right direction for debugging this error. I'm loading an html fragment into a div and then use jqModal to display that div as a modal dialog. The problem is that the div is displayed but not with my updated html. I'm showing my jqModal dialog in the response from a jquery call, function foo is called from an onclick event: function foo(url) { $.ajax({ type: "GET", url: url, success: function(msg) { $('#ajaxmodal').html(msg); $('#ajaxmodal').jqmShow(); } }); } ajaxmodal is a simple div. Initially I thought the problem must be in the html snippet (msg) I'm passing to the callback, but I don't think that's it, I get the err (see below) even when I comment out the $('#ajaxmodal').html(msg) line or pass it hardcode html. I think I have jqModal configured correctly, other calls using our ajaxmodal div work correctly, I'm able to display the modal, update the content based the server response, etc. When I try to debug in firebug, I get the following error following the call to .jqmShow(). I have seen the err on occasion in other places when it seemed maybe the page hadn't loaded yet, and I confess I'm confused about that, since we've wrapped our jqModal selectors in a $(document).ready() call, so maybe I have a larger issue that this call just happens to trigger? From the jquery.jqModal.js file, line 64: js err is $(':input:visible',h.w)[0] is undefined in the line: f=function(h){try{$(':input:visible',h.w)[0].focus();}catch(_){}} When I step through this in firefox, h.w[0] seems ok, it references our '#ajaxmodal' div. Thanks in advance for any suggestions in tracking this down?
