  • How to make an Android UI with images from a designer delivered as layers

    - by Not Me
    I hired a designer to help me redesign the UI for my Android app. For each Activity he gave me an image for the background, which includes any static content like fancy frames for text content; plus images for the buttons, which must fit in to the background image in exact places, to fit into the frames in the background image. However, since Android devices have different screen sizes and aspect ratios, it's easy to fit the background image by itself with android:scaleType="centerInside", but how can I get all the other images to fit in with background exactly, to the pixel? If they didn't have to fit in with the background, I would just set the exact width and height for each ImageButton, but depending on how the background scales (based on the screen size and ratio) they might end up not aligned correctly. Thank you very much in advance.

  • How to assign default values and define unique keys in Entity Framework 4 Designer

    - by csharpnoob
    Hello, I've had a look at the Entity Framework 4. While generating code for the SQL Server 2008 I came to the point where I want to define some default values for some fields. how to define in the designer for a Created DateTime Field the DateTime.Now default value? - Error 54: Default value (DateTime.Now) is not valid for DateTime. The value must be in the form 'yyyy-MM-dd HH:mm:ss.fffZ' how to make for code generation a string Field unique. Like E-Mail or Username can exists only once in the table. I've search alot in the internet and also checked my books Pro Entity Framework 4.0 and Programming Entity Framework. But none of them seems to come up with the default value issue, or using sql commands as default values for database generation. Another thing is, how to prevent on database generation always from droping tables? Instead i want to append non existing fields and keep the data. Thanks for any suggestions.

    - by pdiddy
    Lets say i have an activity with InArgument<int> ProductId I'd like to expose in the activity designer a combobox to show all Products and the user can select a product. I can show the list of product in the combo no problem. But how do I bind the selected product to the InArgument<int> of my custom activity? I suppose I need some kind of ValueConverter? Not sure how to code the value converter for this case, if anybody has an idea, suggestion, will be helpful. I have to convert the InArgument<int> to an int? and the convert back from int to InArgument<int> Thanks,

  • EventSetter - error XAML in Visual Studio designer

    - by pileggi
    Hi! I've done my TreeView all with XAML but now I'd like to manage an event with code-behind. The HierarchicalDataTemplate contains an Image. I need to capture the events MouseEnter / MouseLeave on the Image. I've tried in this way: <Image x:Name="imgArticolo" Source="{Binding imgArt}"> <Image.Style> <Style TargetType="{x:Type Image}"> <EventSetter Event="MouseEnter" Handler="iArt_MouseEnter"/> </Style> </Image.Style> </Image> But in the designer of Visual Studio appear the error: "Impossible to load a file XAML with EventSetter". How can I remedy? Thank you! Pileggi

  • VS2010 is removing code from designer without warning - causing issues

    - by schmoopy
    I have a WinForm with a pretty complex layout (has lots of controls, panels, etc.) Whenever i open the form the file is automatically checked out from source control and it removes anything in the designer file that refereces my menustrip or statusstrip ie: the following get removed (w/o warning) Me.MyMenuStip.SuspendLayout() Me.MyStatusStrip.SuspendLayout() Me.MyMenuStrip.ResumeLayout(False) Me.MyMenuStrip.PerformLayout() Me.MyStatusStrip.ResumeLayout(False) Me.MyStatusStrip.PerformLayout() The code still builds, but there are no Menu or Status items rendered. Any ideas on what i can do? I do not want to just remove/add the menustrip for instance cause i would loose all of my menu items (and there are a lot) Thanks in advance!

  • Number of elements in Python Set

    - by Tim
    I have a list of phone numbers that have been dialed (nums_dialed). I also have a set of phone numbers which are the number in a client's office (client_nums) How do I efficiently figure out how many times I've called a particular client (total) For example: >>>nums_dialed=[1,2,2,3,3] >>>client_nums=set([2,3]) >>>??? total=4 Problem is that I have a large-ish dataset: len(client_nums) ~ 10^5; and len(nums_dialed) ~10^3.

  • Web Designer looking to learn back-end programming...

    - by Tabetha Moe
    Hello, my name is Tabetha and I have a question... I am a web designer, but I always find that while designing the layout and coding the design I come up with great ideas for websites. I would like to know where I need to start in order to learn back-end programming not only for the knowledge, but also for the challenge of it. I have searched online but can't seem to find the information I am looking for. If anyone can give me a simple, straight-forward "this is what language you need to learn" answer, or perhaps guide me in the right direction I would appreciate it ten-fold. I am a complete noob when it comes to this, so even the most basic information is probably a pearl of wisdom for me. :)

  • Order column in a datatable

    - by superartsy
    I have two tables - Parent table (Clients- ClntID,ClntName) And Child Table ( Orders- ClntID,OrderNumber,OrderDate) - Order Number column has a value equal to how many orders the Client has. It is not an autonumber ClntID ClntName 1 Company A 2 Company B ClntID OrderNumber OrderDate 1 1 11/1/2009 1 2 11/15/2009 2 1 2/12/2008 2 1 7/13/2009 If I have a dataset for these tables, how do I insert the data in the Orders table and increment the OrderNumber value correctly.

  • Looking for advice on importing large dataset in sqlite and Cocoa/Objective-C

    - by jluckyiv
    I have a fairly large hierarchical dataset I'm importing. The total size of the database after import is about 270MB in sqlite. My current method works, but I know I'm hogging memory as I do it. For instance, if I run with Zombies, my system freezes up (although it will execute just fine if I don't use that Instrument). I was hoping for some algorithm advice. I have three hierarchical tables comprising about 400,000 records. The highest level has about 30 records, the next has about 20,000, the last has the balance. Right now, I'm using nested for loops to import. I know I'm creating an unreasonably large object graph, but I'm also looking to serialize to JSON or XML because I want to break up the records into downloadable chunks for the end user to import a la carte. I have the code written to do the serialization, but I'm wondering if I can serialize the object graph if I only have pieces in memory. Here's pseudocode showing the basic process for sqlite import. I left out the unnecessary detail. [database open]; [database beginTransaction]; NSArray *firstLevels = [[FirstLevel fetchFromURL:url retain]; for (FirstLevel *firstLevel in firstLevels) { [firstLevel save]; int id1 = [firstLevel primaryKey]; NSArray *secondLevels = [[SecondLevel fetchFromURL:url] retain]; for (SecondLevel *secondLevel in secondLevels) { [secondLevel saveWithForeignKey:id1]; int id2 = [secondLevel primaryKey]; NSArray *thirdLevels = [[ThirdLevel fetchFromURL:url] retain]; for (ThirdLevel *thirdLevel in thirdLevels) { [thirdLevel saveWithForeignKey:id2]; } [database commit]; [database beginTransaction]; [thirdLevels release]; } [secondLevels release]; } [database commit]; [database release]; [firstLevels release];

  • Exporting dataset to Excel file with multiple sheets in ASP.NET

    - by engg
    In C# ASP.NET 3.5 web application, I need to export multiple datatables (or a dataset) to an Excel 2007 file with multiple sheets, and then provide the user with 'Open/Save' dialog box, WITHOUT saving the Excel file on the web server. I have used Excel Interop before. I have been reading that it's not efficient and is not the best approach to achieve this and there are more ways to do it, 2 of them being: 1) Converting data in datatables to an XML string that Excel understands 2) Using OPEN XML SDK 2.0. It looks like OPEN XML SDK 2.0 is better, please let me know. Are there any other ways to do it? I don't want to use any third-party tools. If I use OPEN XML SDK, it creates an excel file, right? I don't want to save it on the (Windows 2003) server hard drive (I don't want to use Server.MapPath, these Excel files are dynamically created, and they are not required on the server, once client gets them). I directly want to prompt the user to open/save it. I know how to do it when the 'XML string' approach is used. Please help. Thank you.

  • ASP.NET Webforms developers and web designers: how to interact?

    - by just_name
    I'm an ASP.NET Webforms developer, and I face some problems when I deal with designers. Designers always complain about the asp.net server controls. They'd rather just have an html file and create css files along with the required images to go with those. Sometimes, if the design phase is done in advance, I get html files with related css files, but then we face many problems integrating the design with the aspx files (sever controls an telerik controls ... etc). What I want to ask about is: How do I overcome these problems? The designers prefer php- and mvc developers because of the problems with .net server controls. I need to know how to interact with the designers in the correct way. Are there any tools or applications to provide the designers with the rendered (html page) of the .aspx pages? By that I mean the page in runtime rather than the aspx in Visual Studio. They do use Web Expression but they want the rendered page in html as well.

  • Phone number mask in a DataView WebPart (DVWP)

    - by PeterBrunone
    This came up today on the [sharepointdiscussions] list.  A user needed to display a read-only field in a phone number format; it's pretty simple, but it may be just what you need.Assuming your list item contains a field called "Phone Number" (with a space), the following XPath will give you a number in the classic US telephone format: <xsl:value-of select="concat('(',substring(@Phone_x0020_Number,1,3),')',substring(@Phone_x0020_Number,4,3),'-',substring(@Phone_x0020_Number,7,4))" /> If you need to mask an input, try this jQuery solution.

  • WPF 4.0 Custom panel won't show dynamically added controls in VS 2010 Designer

    - by Matt Ruwe
    I have a custom panel control that I'm trying to dynamically add controls within. When I run the application the static and dynamically added controls show up perfectly, but the dynamic controls do not appear within the visual studio designer. Only the controls placed declaratively in the XAML appear. I'm currently adding the dynamic control in the CreateUIElementCollection override, but I've also tried this in the constructor without success. Public Class CustomPanel1 Inherits Panel Public Sub New() End Sub Protected Overrides Function MeasureOverride(ByVal availableSize As System.Windows.Size) As System.Windows.Size Dim returnValue As New Size(0, 0) For Each child As UIElement In Children child.Measure(availableSize) returnValue.Width = Math.Max(returnValue.Width, child.DesiredSize.Width) returnValue.Height = Math.Max(returnValue.Height, child.DesiredSize.Height) Next returnValue.Width = If(Double.IsPositiveInfinity(availableSize.Width), returnValue.Width, availableSize.Width) returnValue.Height = If(Double.IsPositiveInfinity(availableSize.Height), returnValue.Height, availableSize.Height) Return returnValue End Function Protected Overrides Function ArrangeOverride(ByVal finalSize As System.Windows.Size) As System.Windows.Size Dim currentHeight As Integer For Each child As UIElement In Children child.Arrange(New Rect(0, currentHeight, child.DesiredSize.Width, child.DesiredSize.Height)) currentHeight += child.DesiredSize.Height Next Return finalSize End Function Protected Overrides Function CreateUIElementCollection(ByVal logicalParent As System.Windows.FrameworkElement) As System.Windows.Controls.UIElementCollection Dim returnValue As UIElementCollection = MyBase.CreateUIElementCollection(logicalParent) returnValue.Add(New TextBlock With {.Text = "Hello, World!"}) Return returnValue End Function Protected Overrides Sub OnPropertyChanged(ByVal e As System.Windows.DependencyPropertyChangedEventArgs) MyBase.OnPropertyChanged(e) End Sub End Class And my usage of this custom panel <Window x:Class="MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:CustomPanel" Title="MainWindow" Height="364" Width="434"> <local:CustomPanel1> <CheckBox /> <RadioButton /> </local:CustomPanel1> </Window>

  • RIA IDE - Visual Studio 2010, FlashBuilder and ExtJS Designer

    - by Ronaldo Junior
    I've been playing around with Flex4 - the trial version - and is really quite good in terms of layout development - since I'm starting a new RIA project and we still on the "what platform" phase I better listen what you guys have to say. In Flashbuilder I can do the layout and mix with the back end script code really fast - the version 4 give me the power to even test the functionality of the server side script, etc and since I can use Fllashbuilder as a Eclipse plugin, I end up with only one IDE. On the other hand, with Silverlight, it looks like if I want a "drag and drop" approach to build my interface I would need Expression Blend and Visual Studio (full or express version). Is there a way out that? I mean, Visual Studio 2010 will come with some sort of Silverlight component palet so that you can easily drag and drop it on your interface like you would do with WPF, etc? I don't wanna use Blend - is way too much for what we need - taking the "coding XAML" by hand is out of question as well. A third approach is to use ExtJS - they have a new designer IDE that looks promising.

  • Creating a 'Custom Designer' Visual Studio 2010 Add-in

    - by Daniel I-S
    A major part of our work is creating and manipulating certain XML files, for which have a custom editor. The editor is starting to get creaky and we are looking at building a replacement. Since VS2010 has recently arrived, ostensibly with an improved add-in architecture (MEF?), I am interested in the possibility of building the editor as a custom editor within Visual Studio. It would have to appear in the same way as the code editor or the Designer - a tab item, of which there can be many open at once, containing the GUI we use to edit the files. It would integrate with VS's Edit menu. It could use the output window to display messages. It would appear the same as any other editor within Visual Studio. Right now, I am looking for examples of add-ins that work in a similar way - ideally with source code - to see whether this model would suit our requirements. I am also looking for any documentation or tutorials relevant to creating a VS2010 add-in, or information about VS2008 add-ins if this is still relevant. Any input is welcome. Thanks!

  • Error Cannot create an Instance of "ObjectName" in Designer when using <UserControl.Resources>

    - by Mike Bynum
    Hi All, I'm tryihg to bind a combobox item source to a static resource. I'm oversimplfying my example so that it's easy to understand what i'm doing. So I have created a class public class A : ObservableCollection<string> { public A() { IKBDomainContext Context = new IKBDomainContext(); Context.Load(Context.GetIBOptionsQuery("2C6C1Q"), p => { foreach (var item in SkinContext.IKBOptions) { this.Add(item); } }, null); } } So the class has a constructor that populates itself using a domaincontext that gets data from a persisted database. I'm only doing reads on this list so dont have to worry about persisting back. in xaml i add a reference to the namespace of this class then I add it as a usercontrol.resources to the page control. <UserControl.Resources> <This:A x:Key="A"/> </UserControl.Resources> and then i use it this staticresource to bind it to my combobox items source.in reality i have to use a datatemplate to display this object properly but i wont add that here. <Combobox ItemsSource="{StaticResource A}"/> Now when I'm in the designer I get the error: Cannot Create an Instance of "A". If i compile and run the code, it runs just fine. This seems to only affect the editing of the xaml page. What am I doing wrong?

  • Designers, Expression or SharePoint Designer, and real source control

    - by David Lively
    I'm trying desperately to move from VSS to a real source control system. Options include TFS and SVN. My designers need to keep their ability to modify source files and instantly preview their changes in a browser without having to commit their changes. Using FPSE with VSS, this works flawlessly, since saving a file causes the copy in the working folder on the dev server to be updated, so they can just save and refresh their browser which is pointed at the dev server. The site in question consists of 350k+ lines of classic ASP code and some new ASP.NET MVC. They only need to be able to modify views within the MVC code, not C#. Though Expression includes a version of Cassini for local debugging, Cassini does not support classic ASP. Surely someone has solved this problem before. It can't be necessary to install IIS on each designer's machine (this is absolutely untenable). I need a way to have a common working folder on a dev webserver updated whenever someone saves a file locally, just like using FPSE. I'd rather not write an FPSE proxy that knows how to talk to TFS/SVN. Any suggestions? (I know I've asked this question in the past, but I haven't yet found a solution.)

  • load complex class/nested xml file into dataset

    - by iTayb
    I want to create a dataset and bind it with a repeater. My datasource is a class, which is itself loaded from an nested xml file. I can use both as datasources. How can I do it? This is my sample XML file: <?xml version="1.0" encoding="utf-8"?> <BookStore xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Book> <Name>??????? ????? 035006</Name> <Imageurl>math1.jpg</Imageurl> <Subject>???????</Subject> <Author>??? ????</Author> <Level>5</Level> <Year>2002</Year> <Rating>4</Rating> <BookSellers> <string>????? ?????</string> <string>?.?. ????? ??"?</string> <string>??? ?? ???? ????? ??????? ??"?</string> <string>?? ?????? ???? ?'????</string> <string>???? ??? ?????</string> <string>Garbage Collector</string> <string>???? ??????? ??????</string> </BookSellers> <BookPrices> <double>25</double> <double>48</double> <double>37</double> <double>52</double> <double>34</double> <double>22</double> <double>60</double> </BookPrices> </Book> </BookStore> Plus, how will I refer to this data? for example, DataBinder.Eval(Container.DataItem, "Imageurl" will bring me the url? Thank you very much!

  • Unable to add item to dataset in Linq to SQL

    - by Mike B
    I am having an issue adding an item to my dataset in Linq to SQL. I am using the exact same method in other tables with no problem. I suspect I know the problem but cannot find an answer (I also suspect all i really need is the right search term for Google). Please keep in mind this is a learning project (Although it is in use in a business) I have posted my code and datacontext below. What I am doing is: Create a view model (Relevant bits are shown) and a simple wpf window that allows editing of 3 properties that are bound to the category object. Category is from the datacontext. Edit works fine but add does not. If I check GetChangeSet() just before the db.submitChanges() call there are no adds, edits or deletes. I suspect an issue with the fact that a Category added without a Subcategory would be an orphan but I cannot seem to find the solution. Command code to open window: CategoryViewModel vm = new CategoryViewModel(); AddEditCategoryWindow window = new AddEditCategoryWindow(vm); window.ShowDialog(); ViewModel relevant stuff: public class CategoryViewModel : ViewModelBase { public Category category { get; set; } // Constructor used to Edit a Category public CategoryViewModel(Int16 categoryID) { db = new OITaskManagerDataContext(); category = QueryCategory(categoryID); } // Constructor used to Add a Category public CategoryViewModel() { db = new OITaskManagerDataContext(); category = new Category(); } } The code for saving changes: // Don't close window unless all controls are validated if (!vm.IsValid(this)) return; var changes = vm.db.GetChangeSet(); // DEBUG try { vm.db.SubmitChanges(ConflictMode.ContinueOnConflict); } catch (ChangeConflictException) { vm.db.ChangeConflicts.ResolveAll(RefreshMode.KeepChanges); vm.db.SubmitChanges(); } The Xaml (Edited fror brevity): <TextBox Text="{Binding category.CatName, Mode=TwoWay, ValidatesOnDataErrors=True, UpdateSourceTrigger=PropertyChanged}" /> <TextBox Text="{Binding category.CatDescription, ValidatesOnDataErrors=True, UpdateSourceTrigger=PropertyChanged}" /> <CheckBox IsChecked="{Binding category.CatIsInactive, Mode=TwoWay}" /> IssCategory in the Issues table is the old, text based category. This field is no longer used and will be removed from the database as soon as this is working and pushed live.

  • Allow a web designer to modify DNS without letting them transfer the domain?

    - by PhilCK
    We are in the process of having a web designer create a new website for us, but I don't want to give access to the control panel for the domain names (and have no way to limit it, it seems), while at the same time I don't want to be the go between guy for editing the settings. Is there a way or a service for me to point the domains at a 3rd party DNS system, that I can then give access for the web designer, without worrying that he can find my personal info or try and transfer my domain out?
