  • Aliasing Resources (WPF)

    - by Noldorin
    I am trying to alias a resource in XAML, as follows: <UserControl.Resources> <StaticResourceExtension x:Key="newName" ResourceKey="oldName"/> </UserControl.Resources> oldName simply refers to a resource of type Image, defined in App.xaml. As far as I understand, this is the correct way to do this, and should work fine. However, the XAML code gives me the superbly unhelpful error: "The application XAML file failed to load. Fix errors in the application XAML before opening other XAML files." This appears when I hover over the StaticResourceExtension line in the code (which has a squiggly underline). Several other errors are generated in the actual Error List, but seem to be fairly irrelevant and nonsenical (such messages as "The name 'InitializeComponent' does not exist in the current context"), as they all disappear when the line is removed. I'm completely stumped here. Why is WPF complaining about this code? Any ideas as to a resolution please? Note: I'm using WPF in .NET 3.5 SP1. Update 1: I should clairfy that I do receive compiler errors (the aforementioned messages in the Error List), so it's not just a designer problem. Update 2: Here's the relevant code in full... In App.xaml (under Application.Resource): <Image x:Key="bulletArrowUp" Source="Images/Icons/bullet_arrow_up.png" Stretch="None"/> <Image x:Key="bulletArrowDown" Source="Images/Icons/bullet_arrow_down.png" Stretch="None"/> And in MyUserControl.xaml (under UserControl.Resources): <StaticResourceExtension x:Key="columnHeaderSortUpImage" ResourceKey="bulletArrowUp"/> <StaticResourceExtension x:Key="columnHeaderSortDownImage" ResourceKey="bulletArrowDown"/> These are the lines that generate the errors, of course.

  • WPF Browser is there, but invisible.

    - by Adam Crossland
    I am attempting to use the Browser control in a very simple WPF application, and it appears that while the browser is loading the page that I requested (I can mouseover images and see the ALT tags), I can't actually see anything else: Here is the XAML for the app: <Window x:Class="SmokeyBox2.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="SmokeyBox" Height="120" Width="510" ShowInTaskbar="False" SizeToContent="WidthAndHeight" WindowStyle="None" AllowsTransparency="True" MouseLeftButtonDown="Window_MouseLeftButtonDown"> <Border Background="#50FFFFFF" CornerRadius="5" BorderThickness="2,0,2,2" Padding="5 1 5 5"> <Grid> <Grid.RowDefinitions> <RowDefinition Height="Auto"></RowDefinition> <RowDefinition Height="Auto"></RowDefinition> <RowDefinition Height="Auto"></RowDefinition> </Grid.RowDefinitions> <Grid.ColumnDefinitions> <ColumnDefinition Width="Auto"></ColumnDefinition> <ColumnDefinition Width="Auto"></ColumnDefinition> </Grid.ColumnDefinitions> <Label Grid.Row="0" Grid.Column="0" Background="Transparent" Content="SmokeyBox" MouseLeftButtonDown="Label_MouseLeftButtonDown" /> <TextBox Grid.Row="1" Grid.Column="0" Name="searchText" Width="450" FontFamily="Arial" Foreground="DarkGray" Background="Transparent" FontSize="20" MouseLeftButtonDown="searchText_MouseLeftButtonDown" BorderBrush="Transparent" /> <Expander Grid.Row="1" Grid.Column="1" Padding="2 3 0 0 " Expanded="Expander_Expanded" Collapsed="Expander_Collapsed" /> <WebBrowser Grid.Row="2" Grid.Column="0" x:Name="browser" Visibility="Visible" Width="480" Height="480" Margin="2 2 2 2" ></WebBrowser> </Grid> </Border> </Window> So can anyone help me figure out why the browser isn't showing the Yahoo! home page like I asked it to? And while I am at it, I'm going to own up to the fact that this is my first WPF app, and I'd love to hear any general pointers on how to get rid of general noobie badness in my XAML. Thanks.

  • WPF vs. WinForms - a Delphi programmer's perspective?

    - by Robert Oschler
    I have read most of the major threads on WPF vs. WinForms and I find myself stuck in the unfortunate ambivalence you can fall into when deciding between the tried and true previous tech (Winforms), and it's successor (WPF). I am a veteran Delphi programmer of many years that is finally making the jump to C#. My fellow Delphi programmers out there will understand that I am excited to know that Anders Hejlsberg, of Delphi fame, was the architect behind C#. I have a strong addiction to Delphi's VCL custom components, especially those involved in making multi-step Wizards and components that act as a container for child components. With that background, I am hoping that those of you that switched from Delphi to C# can help me with my WinForms vs. WPF decision for writing my initial applications. Note, I am very impatient when coding and things like full fledged auto-complete and proper debugger support can make or break a project for me, including being able to find readily available information on API features and calls and even more so, workarounds for bugs. The SO threads and comments in the early 2009 date range give me great concern over WPF when it comes to potential frustrations that could mar my C# UI development coding. On the other hand, spending an inordinate amount of time learning an API tech that is, even if it is not abandoned, soon to be replaced (WinForms), is equally troubling and I do find the GPU support in WPF tantalizing. Hence my ambivalence. Since I haven't learned either tech yet I have a rare opportunity to get a fresh start and not have to face the big "unlearning" curve I've seen people mention in various threads when a WinForms programmer makes the move to WPF. On the other hand, if using WPF will just be too frustrating or have other major negative consequences for an impatient RAD developer like myself, then I'll just stick with WinForms until WPF reaches the same level of support and ease of use. To give you a concrete example into my psychology as a programmer, I used VB and subsequently Delphi to completely avoid altogether the very real pain of coding with MFC, a Windows UI library that many developers suffered through while developing early Windows apps. I have never regretted my luck in avoiding MFC. It would also be comforting to know if Anders Hejlsberg had a hand in the architecture of WPF and/or WinForms, and if there are any disparities in the creative vision and ease of use embodied in either code base. Finally, for the Delphi programmers again, let me know how much "IDE schock" I'm in for when using WPF as opposed to WinForms, especially when it comes to debugger support. Any job market comments updated for 2011 would be appreciated too. -- roschler

    Hello all.

  • Detecting Idle Time with Global Mouse and Keyboard Hooks in WPF

    - by jdanforth
    Years and years ago I wrote this blog post about detecting if the user was idle or active at the keyboard (and mouse) using a global hook. Well that code was for .NET 2.0 and Windows Forms and for some reason I wanted to try the same in WPF and noticed that a few things around the keyboard and mouse hooks didn’t work as expected in the WPF environment. So I had to change a few things and here’s the code for it, working in .NET 4. I took the liberty and refactored a few things while at it and here’s the code now. I’m sure I will need it in the far future as well. using System; using System.Diagnostics; using System.Runtime.InteropServices; namespace Irm.Tim.Snapper.Util { public class ClientIdleHandler : IDisposable { public bool IsActive { get; set; } int _hHookKbd; int _hHookMouse; public delegate int HookProc(int nCode, IntPtr wParam, IntPtr lParam); public event HookProc MouseHookProcedure; public event HookProc KbdHookProcedure; //Use this function to install thread-specific hook. [DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)] public static extern int SetWindowsHookEx(int idHook, HookProc lpfn, IntPtr hInstance, int threadId); //Call this function to uninstall the hook. [DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)] public static extern bool UnhookWindowsHookEx(int idHook); //Use this function to pass the hook information to next hook procedure in chain. [DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)] public static extern int CallNextHookEx(int idHook, int nCode, IntPtr wParam, IntPtr lParam); //Use this hook to get the module handle, needed for WPF environment [DllImport("kernel32.dll", CharSet = CharSet.Auto)] public static extern IntPtr GetModuleHandle(string lpModuleName); public enum HookType : int { GlobalKeyboard = 13, GlobalMouse = 14 } public int MouseHookProc(int nCode, IntPtr wParam, IntPtr lParam) { //user is active, at least with the mouse IsActive = true; Debug.Print("Mouse active"); //just return the next hook return CallNextHookEx(_hHookMouse, nCode, wParam, lParam); } public int KbdHookProc(int nCode, IntPtr wParam, IntPtr lParam) { //user is active, at least with the keyboard IsActive = true; Debug.Print("Keyboard active"); //just return the next hook return CallNextHookEx(_hHookKbd, nCode, wParam, lParam); } public void Start() { using (var currentProcess = Process.GetCurrentProcess()) using (var mainModule = currentProcess.MainModule) { if (_hHookMouse == 0) { // Create an instance of HookProc. MouseHookProcedure = new HookProc(MouseHookProc); // Create an instance of HookProc. KbdHookProcedure = new HookProc(KbdHookProc); //register a global hook _hHookMouse = SetWindowsHookEx((int)HookType.GlobalMouse, MouseHookProcedure, GetModuleHandle(mainModule.ModuleName), 0); if (_hHookMouse == 0) { Close(); throw new ApplicationException("SetWindowsHookEx() failed for the mouse"); } } if (_hHookKbd == 0) { //register a global hook _hHookKbd = SetWindowsHookEx((int)HookType.GlobalKeyboard, KbdHookProcedure, GetModuleHandle(mainModule.ModuleName), 0); if (_hHookKbd == 0) { Close(); throw new ApplicationException("SetWindowsHookEx() failed for the keyboard"); } } } } public void Close() { if (_hHookMouse != 0) { bool ret = UnhookWindowsHookEx(_hHookMouse); if (ret == false) { throw new ApplicationException("UnhookWindowsHookEx() failed for the mouse"); } _hHookMouse = 0; } if (_hHookKbd != 0) { bool ret = UnhookWindowsHookEx(_hHookKbd); if (ret == false) { throw new ApplicationException("UnhookWindowsHookEx() failed for the keyboard"); } _hHookKbd = 0; } } #region IDisposable Members public void Dispose() { if (_hHookMouse != 0 || _hHookKbd != 0) Close(); } #endregion } } The way you use it is quite simple, for example in a WPF application with a simple Window and a TextBlock: <Window x:Class="WpfApplication2.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="MainWindow" Height="350" Width="525"> <Grid> <TextBlock Name="IdleTextBox"/> </Grid> </Window> And in the code behind we wire up the ClientIdleHandler and a DispatcherTimer that ticks every second: public partial class MainWindow : Window { private DispatcherTimer _dispatcherTimer; private ClientIdleHandler _clientIdleHandler; public MainWindow() { InitializeComponent(); } private void Window_Loaded(object sender, RoutedEventArgs e) { //start client idle hook _clientIdleHandler = new ClientIdleHandler(); _clientIdleHandler.Start(); //start timer _dispatcherTimer = new DispatcherTimer(); _dispatcherTimer.Tick += TimerTick; _dispatcherTimer.Interval = new TimeSpan(0, 0, 0, 1); _dispatcherTimer.Start(); } private void TimerTick(object sender, EventArgs e) { if (_clientIdleHandler.IsActive) { IdleTextBox.Text = "Active"; //reset IsActive flag _clientIdleHandler.IsActive = false; } else IdleTextBox.Text = "Idle"; } } Remember to reset the ClientIdleHandle IsActive flag after a check.

  • ASP.Net or WPF(C#)?

    - by Rachel
    Our team is divided on this and I wanted to get some third-party opinions. We are building an application and cannot decide if we want to use .Net WPF Desktop Application with a WCF server, or ASP.Net web app using jQuery. I thought I'd ask the question here, with some specs, and see what the pros/cons of using either side would be. I have my own favorite and feel I am biased. Ideally we want to build the initial release of the software as fast as we can, then slow down and take time to build in the additional features/components we want later on. Above all we want the software to be fast. Users go through records all day long and delays in loading records or refreshing screens kills their productivity. Application Details: I'm estimating around 100 different screens for initial version, with plans for a lot of additional screens being added on later after the initial release. We are looking to use two-way communication for reminder and event systems Currently has to support around 100 users, although we've been told to allow for growth up to 500 users We have multiple locations Items to consider (maybe not initially in some cases but in future releases): Room for additional components to be added after initial release (there are a lot of of these... perhaps work here than the initial application) Keyboard navigation Performance is a must Production Speed to initial version Low maintenance overhead Future support Softphone/Scanner integration Our Developers: We have 1 programmer who has been learning WPF the past few months and was the one who suggested we use WPF for this. We have a 2nd programmer who is familiar with ASP.Net and who may help with the project in the future, although he will not be working on it much up until the initial release since his time is spent maintaining our current software. There is me, who has worked with both and am comfortable in either We have an outside company doing the project management, and they are an ASP.Net company. We plan on hiring 1-2 others, however we need to know what direction we are going in first Environment: General users are on Windows 2003 server with Terminal Services. They connect using WYSE thin-clients over an RDP connection. Admin staff has their own PCs with XP or higher. Users are allowed to specify their own resolution although they are limited to using IE as the web browser. Other locations connects to our network over a MPLS connection Based on that, what would you choose and why? I am asking here instead of SO because I am looking for opinions and not answers

  • 3D transformations in WPF & DirectX/Direct3D or OpenGL

    - by user2723417
    I need your help with 3D transformations. I have a sphere and I want to deform it by a mouse click or a mouse move. I want to make a furrow or to bite off a piece of the sphere without any breaks of 3D material. It is possible in WPF, but if the quantity of 3D points is more then 25 000, it creates some freezes in a dynamic mode (animation breaks), because the object of MeshGeometry3D class should be reconstructed every time to stop the breaks of 3D material. Give me advice about tools for the realization of my task. Maybe it can be done with the help of DirectX/Direct3D or OpenGL? I am a newcomer in these collections of APIs, but I would like to study them. I need to integrate the process of transformation in WPF application.

  • WPF ListBoxItem double-click?

    - by David Veeneman
    The WPF ListBox doesn't have a DoubleClick event, at least not as far as I can tell. Is there a workaround for this issue that would let me double-click on an item to have an event handler do something with it? Thanks for your help.

  • Masked Time control in WPF

    - by Ashish Ashu
    We are in need of a control in which we can show the elapsed time in "Hour:Min:Sec" format. This control should have a spin control attached with it. Whenever we spin the spin window, it should increment the selected option ( Either hour, or min , or sec). Also the Hour may have values between 0 to 99 , Min many have values between 0 to 59 and Sec may have values between 0 to 59. Is anybody know this type of control in WPF?

  • Window out of the screen when maximized using WPF shell integration library

    - by Eduardo Molteni
    I'm using the WPF Shell Integration Library to create a custom chrome of my wpf app. All is good, but when maximizing the app, 6 or 7 pixels are out of the screen.

  • WPF customer control and direct content support

    - by Mmarquee
    I am fairly new to WPF, and am a bit stuck, so any help would be appreciated. I am trying to write WPF custom control that encapsulates several elements of functionality that I already having working (i.e sorting, filtering, standard menus, etc.), but in a nice neat package to avoid repetition. Anyway I have created the custom control (based on control), and then have the following in the Generic.Xaml <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:Controls.ListViewExtended"> <Style TargetType="{x:Type local:ListViewExtended}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type local:ListViewExtended}"> <Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}"> <ListView> <ListView.View> <GridView> <!-- Content goes here --> </GridView> </ListView.View> </ListView> </Border> </ControlTemplate> </Setter.Value> </Setter> </Style> </ResourceDictionary> When I try to add GridViewColumns (or any control really), as below ... <elv:ListViewExtended> <GridView> <GridViewColumn Width="140" Header="Column 1" /> <GridViewColumn Width="140" Header="Column 2" /> <GridViewColumn Width="140" Header="Column 3" /> </GridView> </elv:ListViewExtended> I get the "... does not support direct content" error. I have created a dependancy property (again below) that allows the adding of GridView, but it still doesn't work. public static DependencyProperty GridViewProperty; public static string GridViewHeader(DependencyObject target) { return (string)target.GetValue(GridViewProperty); } public static void GridViewHeader(DependencyObject target, string value) { target.SetValue(GridViewProperty, value); } Thanks in advance

What I want to do is bind a textbox's text in the UI with this list and when i change the value in the textbox then all objects in the list update their height value. I am new in WPF, I have studied the MVVM pattern, I can do simple data binding but i can't figure out how to do this :'( Thanks!

  • WPF binding not updating until after another action

    - by Matthew Stanford
    I have an observable collection bound to a listbox in WPF. One of the options in the window is to use an OpenFileDialog to add an item to the listbox with certain properties. When I use the OpenFileDialog it immeditaely sets two of the properties of the new item in the observable collection. I am using INotifyPropertyChanged to update the listbox. These two new properties are set correctly and now the listbox should display the title contained in the new title property and the title textbox which is bound to the listbox should display the new title as well. However, neither displays the new title upon the closing of the OpenFileDialog and when I click on another item in the listbox and come back to the item I have just changed it updates the title textbox but the title displayed in the list box is not changed until i move the item in the list box that I want to change. Here is the Binding code. ItemsSource="{Binding Path=MyData, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" And here is the implementation of the browse button that is not working (L1 being the listbox) private void browse_Click(object sender, RoutedEventArgs e) { OpenFileDialog opf = new OpenFileDialog(); opf.ShowDialog(); MyData[L1.SelectedIndex].Title = System.IO.Path.GetFileNameWithoutExtension(opf.FileName); MyData[L1.SelectedIndex].Command = opf.FileName; } When I simply type in the text boxes and click out of them it updates the list box immediately with the new information I have put in. I also have a create new button and upon clicking it, it immediately adds a new item to the list box and updates its' properties. The only one that is not updating correctly is this peice of code I have given you. Thanks for your help. EDIT: Here is my implementation of INotifyPropertyChanged private OCLB _MyData; public OCLB MyData { get { return _MyData; } set { _MyData= value; FirePropertyNotifyChanged("MyData"); } } OCLB is the obserable collection. Here is the function FirePropertyNotifyChanged public event PropertyChangedEventHandler PropertyChanged; private void FirePropertyNotifyChanged(string propertyName) { if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); } } Each of these are in the partial class MainWindow for the wpf form. I also have a class for the MyData files (with 4 get/set functions) that are stored in the OCLB(observable collection). There is also a class with functions for the OCLB.

  • Show Hint Tip of a truncated WPF ListBox Item

    - by vbnc141
    Hi, Been searching all over but could not find the answer I am looking for; perhaps I'm not using the correct search term. Anyways, my question is whether there is a property on the WPF ListBox control which I can set that will automatically display the full text of a truncated list item into a Hint Tip? For example, with some WinForm list-container controls, the Hint Tip only appears when the mouse is hovered over a list item that is truncated.
