  • Problem in setting margin of an object on a grid

    - by Pawan
    Hi, I have inherited a class, say CstateUI from Control class. I am creating an object of CstateUI and setting up the margin of the object. For values of margin I take mouse click points from e.getPosition(grid). The problem is the first object is correctly rendered but on subsequent objects margin is not getting set accurately. Can you please tell me what possibly might be going wrong? Thanks in advance!

  • Binding to static property

    - by Anthony Brien
    I'm having a hard time binding a simple static string property to a text box. Here's the class with the static property: public class VersionManager { private static string filterString; public static string FilterString { get { return filterString; } set { filterString = value; } } } In my xaml, I just want to bind this static property to a text box: <TextBox> <TextBox.Text> <Binding Source="{x:Static local:VersionManager.FilterString}"/> </TextBox.Text> </TextBox> Everything compiles, but at run time, I get the following exception: Cannot convert the value in attribute 'Source' to object of type 'System.Windows.Markup.StaticExtension'. Error at object 'System.Windows.Data.Binding' in markup file 'BurnDisk;component/selectversionpagefunction.xaml' Line 57 Position 29. Any idea what I'm doing wrong?

  • MouseLeftButtonDown not recognized by a ListBox ??

    - by Flo
    Hello everybody, I'm encountering a huge problem, I have tried everything I could, but I didn't find any solution. I have a listBox, with a DataTemplate. I want to use the events MouseLeftButtonDown and MouseLeftButtonUp to check the item selected is the same the user clicked on. The problem is the event MouseLeftButtonUp is recognized but not the event MouseLeftButtonDown. Part of my XAML code : < ListBox Grid.Row="1" MouseLeftButtonDown="listBox_Faits_MouseLeftButtonDown" MouseLeftButtonUp="listBox_Faits_MouseLeftButtonUp" The code behind : private void listBox_Faits_MouseLeftButtonUp(object sender, MouseEventArgs e) { ... } private void listBox_Faits_MouseLeftButtonDown(object sender, MouseEventArgs e) { ... } Is anyone know why ? Thanks you, Regards, Flo

  • Safest way to change variable names in a project

    - by kamziro
    So I've been working on a relatively large project by myself, and I've come to realise that some of the variable names earlier on were.. less than ideal. But how does one change variable names in a project easily? Is there such a tool that can go through a project directory, parse all the files, and then replace the variable names to the desired one? It has to be smart enough to understand the language I imagine. I was thinking of using regexp (sed/awk on linux?) tools to just replace the variable name, but there were many times where my particular variable is also included as a part of strings. There's also the issue about changing stuff on a c++ namespace, because there is actually two classes in my project that share the same name, but are in different namespaces. I remember visual stuio being able to do this, but what's the safest and most elegant way to do this on linux?

  • special debugging lines (java)

    - by David
    Recently i've found myself writing a lot of methods with what i can only think to call debugging scaffolding. Here's an example: public static void printArray (String[] array, boolean bug) { for (int i = 0; i<array.lenght; i++) { if (bug) System.out.print (i) ; //this line is what i'm calling the debugging scaffolding i guess. System.out.println(array[i]) ; } } in this method if i set bug to true, wherever its being called from maybe by some kind of user imput, then i get the special debugging text to let me know what index the string being printed as at just in case i needed to know for the sake of my debugging (pretend a state of affairs exists where its helpful). All of my questions more or less boil down to the question: is this a good idea? but with a tad bit more objectivity: Is this an effective way to test my methods and debug them? i mean effective in terms of efficiency and not messing up my code. Is it acceptable to leave the if (bug) stuff ; code in place after i've got my method up and working? (if a definition of "acceptability" is needed to make this question objective then use "is not a matter of programing controversy such as ommiting brackets in an if(boolean) with only one line after it, though if you've got something better go ahead and use your definition i won't mind) Is there a more effective way to accomplish the gole of making debugging easier than what i'm doing? Anything you know i mean to ask but that i have forgotten too (as much information as makes sense is appreciated).

  • How to get parent item in Treeview

    - by Anu
    Hi,To get the child items as string i used the following code private void treeview1_SelectedItemChanged(object sender, RoutedPropertyChangedEventArgs<object> e) { if (treeview1.SelectedItem != null) { Animal bar = (Animal)treeview1.SelectedItem; string str = bar.Name; int boxty = bar.BoxType; int boxno = bar.BoxNo; } } It works fine .But when i click on parent(instead of + sign),it goes to this code and shows error.Ofcourse im casting SelectedItem to my List-Animal. But i dont want this.I have to check,whether the clciked item is parent,if it is so then i will skip this coding.Only when i click the child items it will go to this coding. How can i do that?How can i identify the selected item is parent.

  • Google Web Toolkit or Microsoft Technology (Silverlight, ASP.NET)

    - by NativeByte
    We have a large code base in MFC and VB. A few applications are in .NET. All these applications interoperate with each other on the user's machine and also connect with Unix servers via sockets. Recently we have started discussing a re-write of our applications and possibility of moving a lot of these desktop applications to web (they would run in intranet). A straight forward way is rewritting them in one of the .NET technologies. But a suggestion about using Google Web tookit has popped up and the argument is that it would help creating applications that would run in a browser on both desktop and mobile devices. One of the key problem that I see is that GWT is a large abstraction over Javascript. This will require the team to learn GWT, Javascript, IDEs etc as their experience has been primarily Microsoft technologies and not Java. It would be easier for them to learn .NET technologies instead of GWT. I do not have a depth of GWT and its drawback pittfalls and do not know about a parallel Microsoft Technology that I should investigate. So I would appreciate if people here can share their views or experiences using GWT or equivalent Microsoft technology.

  • Way to get VS 2008 to stop forcing indentation on namespaces?

    - by Earlz
    I've never really been a big fan of the way most editors handle namespaces. They always force you to add an extra pointless level of indentation. For instance, I have a lot of code in a page that I would much rather prefer formatted as namespace mycode{ class myclass{ void function(){ foo(); } void foo(){ bar(); } void bar(){ //code.. } } } and not something like namespace mycode{ class myclass{ void function(){ foo(); } void foo(){ bar(); } void bar(){ //code.. } } } Honestly, I don't really even like the class thing being indented most of the time because I usually only have 1 class per file. And it doesn't look as bad here, but when you get a ton of code and lot of scopes, you can easily have indentation that forces you off the screen, and plus here I just used 2-space tabs and not 4-space as is used by us. Anyway, is there some way to get Visual Studio to stop trying to indent namespaces for me like that?

  • Which syntax is better for return value?

    - by Omar Kooheji
    I've been doing a massive code review and one pattern I notice all over the place is this: public bool MethodName() { bool returnValue = false; if (expression) { // do something returnValue = MethodCall(); } else { // do something else returnValue = Expression; } return returnValue; } This is not how I would have done this I would have just returned the value when I knew what it was. which of these two patterns is more correct? I stress that the logic always seems to be structured such that the return value is assigned in one plave only and no code is executed after it's assigned.

  • Dependency Property ListBox

    - by developer
    Hi All, I want to use a dependency property, so that my label displays values selected in the listbox. This is just to more clearly understand the working of a dependency property. <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:WPFToolkit="clr-namespace:Microsoft.Windows.Controls;assembly=WPFToolkit" xmlns:local="clr-namespace:WpfApplication1" x:Name="MyWindow" Height="200" Width="300" > <StackPanel> <ListBox x:Name="lbColor" Width="248" Height="56" ItemsSource="{Binding TestColor}"/> <StackPanel> <Label Content="{Binding Path=Test, ElementName=lbColor}" /> </StackPanel> </StackPanel> </Window> Code Behind, namespace WpfApplication1 { /// <summary> /// Interaction logic for Window1.xaml /// </summary> public partial class Window1 : Window { public ObservableCollection<string> TestColor { get; set; } public String Test { get { return (String)GetValue(TestProperty); } set { SetValue(TestProperty, value); } } // Using a DependencyProperty as the backing store for Title. This enables animation, styling, binding, etc... public static readonly DependencyProperty TestProperty = DependencyProperty.Register("Test", typeof(String), typeof(ListBox), new UIPropertyMetadata("Test1")); public Window1() { InitializeComponent(); TestColor = new ObservableCollection<string>(); DataContext = this; TestColor.Add("Red"); TestColor.Add("Orange"); TestColor.Add("Yellow"); TestColor.Add("Green"); TestColor.Add("Blue"); } } } Can anyone explain me how will I accompalish this using a dependency property. Somehow I am very confused with the Dependency Property concept, and I just wanted to see a working example for that.

  • How to highlight matching sub-strings inside a ListBox?

    - by Kishore Kumar
    I have one TextBox and one listbox for searching a collection of data. While searching a text inside a Listbox if that matching string is found anywhere in the list it should show in Green color with Bold. eg. I have string collection like "Dependency Property, Custom Property, Normal Property". If I type in the Search Text box "prop" all the Three with "prop" (only the word Prop) should be in Bold and its color should be in green. Any idea how it can be done?. Data inside listbox is represented using DataTemplate.

  • Css attribute selector for input type="button" not working on IE7

    - by Cesar Lopez
    Hi all, I am working on a big form and it contains a lot of buttons all over the form, therefore I am trying to get working input[type="button"] in my main css file so it would catch all buttons with out having to add a class to every single one, for some reason this is not working on IE7, after checking on the web it says that IE7 should be supporting this. Also it has to be type="button" and not type="submit" as not all buttons will submit the form. Could anybody give a hint what am I doing wrong? input[type="button"]{ text-align:center; } I have also tried input[type=button] Any help would be very much apreciated.

  • Suppressing PostSharp Multicast with Attribute

    - by Dan Bryant
    I've recently started experimenting with PostSharp and I found a particularly helpful aspect to automate implementation of INotifyPropertyChanged. You can see the example here. The basic functionality is excellent (all properties will be notified), but there are cases where I might want to suppress notification. For instance, I might know that a particular property is set once in the constructor and will never change again. As such, there is no need to emit the code for NotifyPropertyChanged. The overhead is minimal when classes are not frequently instantiated and I can prevent the problem by switching from an automatically generated property to a field-backed property and writing to the field. However, as I'm learning this new tool, it would be helpful to know if there is a way to tag a property with an attribute to suppress the code generation. I'd like to be able to do something like this: [NotifyPropertyChanged] public class MyClass { public double SomeValue { get; set; } public double ModifiedValue { get; private set; } [SuppressNotify] public double OnlySetOnce { get; private set; } public MyClass() { OnlySetOnce = 1.0; } }

    I've got a simple window, that is container for various views. I've got a DataTemplate that shows the correct view based on whatever the window's MainViewModel property is set to. <DataTemplate DataType="{x:Type VM:StartupViewModel}"> <AdornerDecorator> <V:StartupView /> </AdornerDecorator> </DataTemplate> What I'd like to do is for certain views, change some properties on the base window, ie WindowStyle, ResizeMode etc. something like triggers, but on datatypes instead of property values? How could I accomplish this?

  • Raising event in custom control.

    Hi all, I'm writing a custom textblock control thats populate hyperlinks and raises event when clicked to hyperlink. I wrote this code but I got stucked. My code is : Imports System.Text.RegularExpressions Public Class CustomTextBlock Inherits TextBlock Public Event Klik As EventHandler(Of EventArgs) Public ReadOnly InlineCollectionProperty As DependencyProperty = DependencyProperty.Register("InlineCollection", GetType(String), GetType(CustomTextBlock), New PropertyMetadata(New PropertyChangedCallback(AddressOf CustomTextBlock.InlineChanged))) Private Shared Sub InlineChanged(ByVal sender As DependencyObject, ByVal e As DependencyPropertyChangedEventArgs) DirectCast(sender, CustomTextBlock).Inlines.Clear() Dim kelimeler = Split(e.NewValue, " ") For i = 0 To kelimeler.Length - 1 If Regex.Match(kelimeler(i), "(http|ftp|https):\/\/[\w\-_]+(\.[\w\-_]+)+([\w\-\.,@?^=%&amp;:/~\+#]*[\w\-\@?^=%&amp;/~\+#])?").Success Then Dim x = New Hyperlink(New Run(kelimeler(i))) x.AddHandler(Hyperlink.ClickEvent, New RoutedEventHandler(AddressOf t_Click)) x.ToolTip = kelimeler(i) x.Tag = kelimeler(i) DirectCast(sender, CustomTextBlock).Inlines.Add(x) If Not i = kelimeler.Length Then DirectCast(sender, CustomTextBlock).Inlines.Add(" ") Else DirectCast(sender, CustomTextBlock).Inlines.Add(kelimeler(i)) If Not i = kelimeler.Length Then DirectCast(sender, CustomTextBlock).Inlines.Add(" ") End If ''//Console.WriteLine(kelime(i).ToString.StartsWith("@")) Next kelimeler = Nothing End Sub Public Property InlineCollection As String Get Return DirectCast(GetValue(InlineCollectionProperty), String) End Get Set(ByVal value As String) SetValue(InlineCollectionProperty, value) End Set End Property Private Shared Sub t_Click(ByVal sender As Hyperlink, ByVal e As System.Windows.RoutedEventArgs) e.Handled = True RaiseEvent Klik(sender, EventArgs.Empty) End Sub End Class This code gives error at RaiseEvent Klik(sender, EventArgs.Empty) Error is : Cannot refer to an instance member of a class from within a shared method or shared member initializer without an expliticit instance of the class.

  • Dynamcally resizing an open Accordion

    - by alavers
    I have an Accordion and the height of its content can be dynamically resized. I would like to see the Accordion dynamically respond to the child item's height, but I'm having trouble doing this. <lt:Accordion Name="MyAccordion" SelectionMode="ZeroOrOne" HorizontalAlignment="Stretch"> <lt:AccordionItem Name="MyAccordionItem" Header="MyAccordion" IsSelected="True" HorizontalContentAlignment="Stretch" VerticalAlignment="Stretch"> <StackPanel> <Button Content="Grow" Click="Grow"/> <Button Content="Shrink" Click="Shrink"/> <TextBox Name="GrowTextBox" Text="GrowTextBox" Height="400" Background="Green" SizeChanged="GrowTextBox_SizeChanged"/> </StackPanel> </lt:AccordionItem> </lt:Accordion> private void Grow(object sender, System.Windows.RoutedEventArgs e) { GrowTextBox.Height += 100; } private void Shrink(object sender, System.Windows.RoutedEventArgs e) { GrowTextBox.Height -= 100; } private void GrowTextBox_SizeChanged(object sender, System.Windows.SizeChangedEventArgs e) { MyAccordion.UpdateLayout(); MyAccordionItem.UpdateLayout(); } Mind you, if I collapse and then re-open the accordion, it takes shape just the way I want, but I'd like this resizing to occur immediately when the child resizes. I feebly attempted to fix this by adding a SizeChanged event handler that calls UpdateLayout() on the Accordion and AccordionItem, but this doesn't have any visual effect. I can't figure out where proper resizing takes place inside the Accordion control. Does anyone have an idea?

  • best practice on precedence of variable declaration and error handling in C

    - by guest
    is there an advantage in one of the following two approaches over the other? here it is first tested, whether fopen succeeds at all and then all the variable declarations take place, to ensure they are not carried out, since they mustn't have had to void func(void) { FILE *fd; if ((fd = fopen("blafoo", "+r")) == NULL ) { fprintf(stderr, "fopen() failed\n"); exit(EXIT_FAILURE); } int a, b, c; float d, e, f; /* variable declarations */ /* remaining code */ } this is just the opposite. all variable declarations take place, even if fopen fails void func(void) { FILE *fd; int a, b, c; float d, e, f; /* variable declarations */ if ((fd = fopen("blafoo", "+r")) == NULL ) { fprintf(stderr, "fopen() failed\n"); exit(EXIT_FAILURE); } /* remaining code */ } does the second approach produce any additional cost, when fopen fails? would love to hear your thoughts!
