    - by Andreas Strandfelt
    Hello. I have created a simple method to check if an image has been approved and finally returns it as an control. But how do i call and show it on the page? I've tried something like this in the aspx-file: <% SendImage("DKBygMiniLogo.gif", "True"); %> Here is the simple method: protected Image SendImage(object Image, object Approved) { bool approved = Convert.ToBoolean(Approved); Image img = new Image(); if (approved) { img.ImageUrl = "~/images/Ads/" + Image.ToString(); img.Visible = true; } else { img.ImageUrl = "~/images/Ads/" + Image.ToString(); img.Visible = false; } return img; } How do I actually show the image?

  • MEF instance management

    - by Lawrence A. Contreras
    I am working on application that has multiple modules and sub modules. Here's what I need to do: ModuleA has a sub module SubModuleA, SubModuleB, SubModuleC. I want to export ModuleA, SubModuleA, SubModuleB, SubModuleC. ModuleA can have multiple instances. Whenever I import ModuleA inside the sub modules, I want to get the correct instance and also when I import SubModuleA,SubModuleB and SubModuleC inside other classes. How can I manage that scenario using MEF? Do I really need to use MEF. Updated: Here's a quick example: public class School { List<Classroom> classRooms { get; set; } } [Export] public class Classroom { List<Teacher> teachers { get; set; } } public class Teacher { List<Student> students { get; set; } } public class Student { [Import] Classroom classroom { get; set; } } As you can see, I want to export the classroom class because I need to import it in the Student class, let's just say that I really need the classroom class inside the student class. I want to skip the part where we pass the classroom to the teacher and from the teacher we'll pass it to the student. But when I import classroom, I want to have the correct instance where that class room contains the teacher of the student.

  • How to make margin be relative to the center of the UIElement and not its top-left corner in a Grid?

    - by Nockawa
    I'd like the Margin property to reference the center of the UIElement and not the top-left corner. That way when I change the width/height of the UIElement it stays in the same spot. Is there a way to configure this behavior or I'll have to rely on Binding to make the adjustment ? Thanks. For instance if I change the Width/Height of the following rectangle, its center will move. <Grid> <Rectangle Fill="#FF991C1C" Width="10" Height="40" HorizontalAlignment="Left" Margin="90,161,0,0" VerticalAlignment="Top"/> </Grid>

  • Issue displaying a local image from XAML

    - by Flack
    Hello, I have the below simple xaml: <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"> <Grid> <Image Source="happyface.jpg"/> </Grid> </Window> happyface.jpg is included in the project and its Build Action is set to "Content" and Copy To Ouptput Directory is set to "Copy Always". When looking at the app through the VS designer, everything is ok and I see the image. However, when I run the app, no image is displayed. I see the image is copied to the out out directory. If I put in the entire path as the source (C:\SANDBOX\WpfApplication1\WpfApplication1\bin\Debug") it works. Any ideas as to why the image is not displayed when I run the app? I read about pack URIs but thought that to just simply reference a loose image in the current directory, I can just use the image name. Thank you.

  • Set ListBoxItem.IsSelected when child TextBox is Focused

    - by jpsstavares
    Hi, I have a typical MVVM scenario: I have a ListBox that is binded to a List of StepsViewModels. I define a DataTemplate so that StepViewModels are rendered as StepViews. The StepView UserControl have a set of labels and TextBoxs. What I want to do is to select the ListBoxItem that is wrapping the StepView when a textBox is focused. I've tried to create a style for my TextBoxs with the following trigger: <Trigger Property="IsFocused" Value="true"> <Setter TargetName="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type ListBoxItem}}}" Property="IsSelected" Value="True"/> </Trigger> But I get an error telling me that TextBoxs don't have an IsSelected property. I now that but the Target is a ListBoxItem. How can I make it work?

  • Stretch ListBox Items hit area to full width if the ListBox?

    - by Nicholas
    I've looked around for an answer on this, but the potential duplicates are more concerned with presentation than interaction. I have a basic list box, and each item's content is a simple string. The ListBox itself is stretched to fill it's grid container, but each ListBoxItem's hitarea does not mirror the ListBox width. It looks as if the hitarea (pointer contact area) for each item is only the width of the text content. How do I make this stretch all the way across, regardless of the text size. I've set HorizontalContentAlignment to Stretch, but this doesn't solve my problem. My only other guess is that the content is actually stretching, but the background is invisible and so not capturing the mouse pointer. <ListBox Grid.Row="1" x:Name="ProjectsListBox" DisplayMemberPath="Name" ItemsSource="{Binding Path=Projects}" SelectedItem="{Binding Path=SelectedProject}" HorizontalContentAlignment="Stretch"/> The XAML is pretty straight forward on this. If I mouse over the text in one of the items, then the entire width of the item becomes active. I guess I just need to know how to create an interactive background that is invisible.

  • Delay KeyUp Action if User is Typing (C#)

    - by Kirk
    I have a function that is being called when the user is typing in a search box. I want to wait for the user to finish typing before I actually execute the function. I know how to easily accomplish this in JavaScript with timeouts, but how would I go about doing the same thing in C#? Also, how long should I wait before I assume the user is done typing? 100ms?

  • A Delphi Custom Control: A TRichEdit with a TLabel Above It

    - by doubleu
    Hello, I want to create an custom control (descendant of TRichEdit). I simply want add some text above the editfield. I've created my own control and I override the constructor to create a TLabel for the caption. It works, but my problem: How is it possible to move the label above the richedit? When I set Top := -5 the label begins to disappaer. Here's the code of the constructor: constructor TDBRichEditExt.Create(AOwner: TComponent); begin inherited; lblCaption := TLabel.Create(self); lblCaption.Parent := parent; lblCaption.Caption := 'Header'; lblCaption.Top := -5; end; I think it's logic that the label disappaers since the richedit is the parent. I've tried lblCaption.Parent := self.parent; To make the form which owns the richedit the parent - but this dosn't work... How could I achieve this? Thank you all!

  • Rotating Cursor According to Rotated TextBox

    - by j-t-s
    Hi All I have a TextBox that I allow my users to rotate. But what I would LOVE for my users is to have their Cursor rotate to the same angle that the TextBox was rotated at. For example, if they rotated the TextBox to 28°, then when the Cursor enters that TextBox the Cursor should also rotate itself to 28°. Any help at all will be greatly appreciated. Thank you :)

    - by Vitalij
    I have started using MVVM pattern recently. I have had several projects where I used it and with every new one, I start to see that it will fit great within that new project. And now I start to ask myself are there situation when it's better NOT to use MVVM. Or is it such a nice pattern which you can use anywhere? Could you please describe several scenarios where MVVM wouldn't be the best choice?

  • InPlaceBitmapMetadataWriter.TrySave() returns true but does nothing

    - by mephisto123
    On some .JPG files (EPS previews, generated by Adobe Illustrator) in Windows 7 InPlaceBitmapMetadataWriter.TrySave() returns true after some SetQuery() calls, but does nothing. Code sample: BitmapDecoder decoder; BitmapFrame frame; BitmapMetadata metadata; InPlaceBitmapMetadataWriter writer; decoder = BitmapDecoder.Create(s, BitmapCreateOptions.PreservePixelFormat | BitmapCreateOptions.IgnoreColorProfile, BitmapCacheOption.Default); frame = decoder.Frames[0]; metadata = frame.Metadata as BitmapMetadata; writer = frame.CreateInPlaceBitmapMetadataWriter(); try { writer.SetQuery("System.Title", title); writer.SetQuery(@"/app1/ifd/{ushort=" + exiftagids[0] + "} ", (title + '\0').ToCharArray()); writer.SetQuery(@"/app13/irb/8bimiptc/iptc/object name", title); return writer.TrySave(); } catch { return false; } Image sample You can reproduce problem (if you have Windows 7) by downloading image sample and using this code sample to set title on this image. Image has enough room for metadata - and this code sample works fine on my WinXP. Same code works fine on Win7 with other .JPG files. Any ideas are welcome :)

  • Labelsize appears bigger in VB.Net

    - by Ikke
    I'm trying to stack a few lists on top of each other. But the label.size.height appears to be bigger then the label itself. When i set the borderstyle to fixedsingle, i see the border around the text. But the height is bigger, so there comes a space between one label and the next. I have tried to set margin and padding to 0 without result. Exemple: label.size.height return 23, when the height actually is something around 15. Does someone knows how i get the right size? Edit: When i explicitly set the height of the lable, the problem is solved. Is this some problem with autosize?

  • TargetInvocationException?

    - by Mark
    Why would these lines of code cause that exception private Dispatcher dispatcher = null; public DownloadManager(Dispatcher dispatcher = null) { this.dispatcher = dispatcher ?? Dispatcher.CurrentDispatcher; } When the DownloadManager is instantiated in the XAML like <Window.DataContext> <c:DownloadManager /> </Window.DataContext> ?

  • What types of objects should the ViewModel reference in the MVVM pattern?

    - by Blanthor
    I've seen quite a few examples of MVVM. I can see that the View should reference the ViewModel. I've seen recently an example of a ViewModel referencing a View, which seems wrong to me, as it would result in tighter coupling. Given that ViewModel is often described as an intermediary between the View and the Model, is there more to the ViewModel than a facade to domain objects? I hope I used the term "facade" correctly here.

  • Ensure that my C# desktop application is making requests to my ASP .NET MVC action?

    - by Mathias Lykkegaard Lorenzen
    I've seen questions that are almost identical to this one, except minor but important differences that I would like to get detailed. Let's say that I have a controller and an action method in MVC which therefore accepts requests on the following URL: http://example.com/api/myapimethod?data=some-data-here. This URL is then being called regularly by 1000 clients or more spread out in the public. The reason for this is crowdsourcing. The clients around the globe help feed a global cache on my server, which makes it faster for the rest of the clients to fetch the data. Now, if I'm sneaky (and I am), I can go into Fiddler, Ethereal, Wireshark or any other packet sniffing tool and figure out which requests the program is making. By figuring that out, I can also replicate them, and fill the service with false corrupted data. What is the best approach to ensuring that the data received in my ASP .NET MVC action method is actually from the desktop client application, and not some falsely generated data that the user invented? Since it is all based on crowdsourcing, would it be a good idea for my users to be able to "vote" if some data is falsified, and then let an automatic cleanup commence if there are enough votes? I do not have access to a tool like SmartAssembly, so unfortunately my .NET program is fully decompilable. I realize this might be impossible to accomplish in an error-proof manner, but I would like to know where my best chances are.
