As a reference I have used the source from https://support.microsoft.com/kb/322091/en-us?wa=wsignin1.0 for  RawPrinterHelper. This is working great.

Now the problem I am having is, I have two computers and one printer with two printer output Trays or Bins. I configured  Printer Settings in both the computers, so that first computer prints papers to tray1 and second computer prints papers to tray2. These are working as expected when I print local documents. but when I use RawPrinterHelper, all the papers going to tray1. How to handle this issue?

Thank you.

How do I bring up the Visual Studio Designer's property setting window?

I started WPF Application but the design with XAML code is too tedious.

I want to set properties of controls with property window, not code.

I can't see property setting window in my Visual Studio 2010.

I am using RichTextBox in one of my WPF Application, users types Text\script in this rich text box, based on the tokens entered by user i apply color, font property to the entered text in the code behind(Syntax highlighting).

I need to perform Undo\Redo Operations, but what i found is the default undo operation works well if i am not changing the color\font properties, but if i change them in my code , it doesn't work.

Is there any issues with Richtextbox ?

Hi,

There's an issue in WindowsFormsIntegration.dll, in class ApplicationInterop, which did not check for the menu state in the right time. The problem exists in version4.0.30319.1, and is fixed in version4.0.30319.17929. How can I know which .Net framework version the fix can be found in? I know it is not in the original .Net 4.5 version, but I need to know which version it is in, and is it available for .Net 4.0 as well.

Hello,

I'm having trouble with my ResourceDictionary. I have a generic.xaml (Build Action=Page)

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                    xmlns:my="clr-namespace:siemens.CSharp.JobManagement"
                    x:Class="IPIPEResourceDictionary"><ResourceDictionary.MergedDictionaries><ResourceDictionary Source="/siemens.CSharp;component/themes/buttons.xaml"/><ResourceDictionary Source="/siemens.CSharp;component/themes/colors.xaml"/><ResourceDictionary Source="/siemens.CSharp;component/themes/controls.xaml"/></ResourceDictionary.MergedDictionaries><Color x:Key="TEST">#25254E</Color></ResourceDictionary>

all other ResourceDictionaries are set to Build Action=Content.

The AssemblyInfo.cs has following entry

[assembly: ThemeInfo(ResourceDictionaryLocation.None, ResourceDictionaryLocation.SourceAssembly)]

In one of the resource dictionaries I have a Style

<Style TargetType="{x:Type my:IPIPEStatusSideBarView}"><Setter Property="Height" Value="150"/><Setter Property="Width" Value="350"/><Setter Property="Margin" Value="350,0,0,0"/><Setter Property="Background" Value="#65658E"/>

and I have a control that overrides the style key:

public class IPIPEStatusSideBarView : UserControl
	{
		static IPIPEStatusSideBarView()
		{
			DefaultStyleKeyProperty.OverrideMetadata(typeof(IPIPEStatusSideBarView), new FrameworkPropertyMetadata(typeof(IPIPEStatusSideBarView)));

			//GetDefaultStyle()));
		}

The problem is, that the style never gets applied. I have done some testing a found an interesting thing:

var foo = new Uri("Themes/generic.xaml", UriKind.RelativeOrAbsolute);
			ResourceDictionary dict = new ResourceDictionary();

			dict.BeginInit();
			dict.Source = foo;
			dict.EndInit();


			Style = dict["TEST"] as Style;
			Style = dict[typeof(IPIPEStatusSideBarView)] as Style;
			Style = dict[typeof(IPIPEStatusSideBarView)] as Style;

If I access "TEST" it gives my the value immediately. If I access IPIPEStatusSideBarView I get the value only the second time. If I put it one level up into the main dictionary, it works immediately.

What could be wrong. Why is it loaded in some lazy way?

Thanks

Hi!

I am currently working on a software that uses NativeActivities to describe a sequence consisting of different objects, but the GetParentchain class does not seem to work.

Supposing I have the Native Activities : Globe, Continent, Country, City., which are used asModelItems

Globe has a collection of coninents, countries, and cities

Continent cas a collection of countries and cities

and countries has a collection of cities.

I want to Validate the the above rules using a the CheckParent Function example on the msdn Declarative constraints webpage.

After writing the constraint exactly as described above and callling it throuth the following snippet , the constraint does not seem to work

        public static ValidationResults Validate_ModelItem(ModelItem item)
        {
            ValidationResults results = null;
            results = ActivityValidationServices.Validate((NativeActivity)item.GetCurrentValue());
            return results;
        }

I'm running into an unusual one that I can't explain and hoping someone can enlighten me.  I've got an XBAP app that interacts with the default.aspx (ASP.NET) page through the BrowserInteropHelper.HostScript object to call a javascript function. This functionality works just fine from the root XBAP application, but our app can open up new WPF Windows.  When trying to access the HostScript from these new Windows we are getting null returned. The parent object is still showing as a web browser, but no joy.

In WPF, when you create a "new Window()" in an XBAP app is this window still running under IE or running as a desktop window?  Is there a way to indicate the new window should run inside an IE iframe or inject the HostScript some how so the window has access to it?

Basically I'm trying to block the IE Help command from opening using JavaScript which works great in the main page but new windows still launch the IE Help as well as my own when using F1.

I have this form in my MVVM application.

<UserControl xmlns:behaviors="clr-namespace:....">
  ....<UserControl.InputBindings><KeyBinding Key="D1" Command="{Binding KeyCommand}" CommandParameter="{x:Static behaviors:HotKeyCommand.Random}"/></UserControl.InputBindings><Grid>
		...<TextBox Name="N1"  behaviors:TextBoxBehavior.Check="true">
		...</Grid></UserControl>

In "behaviors" setallowed keys input for TextBox:

private static void CheckPreviewKeyDown(object sender, KeyEventArgs e)
        {
            switch (e.Key)
            {
                case Key.NumPad0:
                case Key.NumPad1:
                case Key.NumPad2:
                    break;
                default:
                    e.Handled = true;
                    break;
            }
        }

Hi!i have a problem.

This code works

<ListView.ItemContainerStyle><Style TargetType="ListViewItem"><Setter Property="ToolTip" Value="someTextHere"/></Style></ListView.ItemContainerStyle>

but this, no.  

<ListView.ItemContainerStyle><Style TargetType="ListViewItem"><Setter Property="ToolTip" Value="{Binding ArticuloSeleccionado.Descripcion"/></Style></ListView.ItemContainerStyle>

ArticuloSeleccionado.Descripcion is string.

Good morning,

I already implemented a application that loads images from a directory to a listbox. All ok but the loading takes about 5 seconds to display around 20-30 images. Is there a way to decrease the time needed for the images to be loaded. Or is it correct to display an loading image in front of the UI so the user knows images are loading? Thank you in advance for the help. Below is my xaml code for the listbox.

<ListBox Name="Images" ListBox.SelectionChanged="lstImagesChange_Click" Grid.Column="1"
                 ScrollViewer.HorizontalScrollBarVisibility="Disabled" VirtualizingStackPanel.IsVirtualizing="false"
                 VirtualizingStackPanel.VirtualizationMode="Recycling" ScrollViewer.IsDeferredScrollingEnabled="True"><ListBox.Resources><Style x:Key="{x:Type ScrollBar}" TargetType="{x:Type ScrollBar}"><Style.Triggers><Trigger Property="Orientation" Value="Vertical"><Setter Property="Width" Value="20"/><Setter Property="Height" Value="Auto" /></Trigger></Style.Triggers></Style></ListBox.Resources><ListBox.ItemsPanel><ItemsPanelTemplate><WrapPanel IsItemsHost="True" Orientation="Horizontal" FlowDirection="LeftToRight" /></ItemsPanelTemplate></ListBox.ItemsPanel><ListBox.ItemTemplate><DataTemplate><Border BorderThickness="2" BorderBrush="#bb62d8" Background="Black" Width="200" Height="200" Margin="5,5,10,5" CornerRadius="10"><Image Source="{Binding Path=Path, Converter={StaticResource UriToBitmapConverter}}" Tag="{Binding ImageID}" /></Border></DataTemplate></ListBox.ItemTemplate></ListBox>

and below is the code loading the images

if (!(images == null))
            {
                Images.ItemsSource = images;
            }

I have a major issue in my applicaiton due to this issue, Could have been in the base framework for decoding TIF issue.

DECODE PIXEL HEIGHT/WIDTH

"The JPEG and Portable Network Graphics (PNG) codecs natively decode the image to the specified size; other codecs decode the image at its original size and scale the image to the desired size."

in order to display thumbnail in Listbox wrappanel, Image source is been generated with Decodepixels.

This is working neat for JPEGS, where as for TIF it sucks, takes ages for loading.

XAML:

<ListBox Name="scannedimages"  Background="Gray"  SelectionMode="Multiple" Grid.Column="0" Grid.ColumnSpan="2" Grid.Row="1" ItemsSource="{Binding }" ScrollViewer.HorizontalScrollBarVisibility="Disabled">
            <ListBox.ItemsPanel>
                <ItemsPanelTemplate>
                    <WrapPanel IsItemsHost="True" Orientation="Horizontal"  ></WrapPanel>
                </ItemsPanelTemplate>
            </ListBox.ItemsPanel>
            <ListBox.ItemTemplate>
                <DataTemplate>
                    <Image Source="{Binding Path=ImageSource}"></Image>
                </DataTemplate>
            </ListBox.ItemTemplate>
        </ListBox>

Class with ImageSource property, setting the property on binding the path in delegate

private void  setvalues()
        {
           if(FullPath!=null)
           {
               //if (System.IO.Path.GetExtension(FullPath.ToString()).ToUpper() == ".TIF")
               //{

               //    Stream tiff = new System.IO.FileStream(FullPath.ToString(), FileMode.Open, FileAccess.Read, FileShare.Read);
               //    TiffBitmapDecoder tiffdec = new TiffBitmapDecoder(tiff, BitmapCreateOptions.DelayCreation, BitmapCacheOption.OnLoad);
               //    BitmapSource bs = tiffdec.Frames[0];
               //    ImageSource = bs;

           }

        }

CODE BEHIND:

- I have also used URItoBitmap converter for direct binding in XAML code

- You notice- I have used different approaches nothing is working as fast as JPEGs loading. appreciate your help.

Hi everyone,

I'm currently making an application which contains 1 window and many similar formatted page (width = 500, height = 600).

How can I make the window fit to content and cannot be resized to be smaller but bigger.

Thank you :)

Hello,

I want to display a expandable list of categories. Each category has a name, an amount, and a list of its styles. Each style also has a name, an amount, and a list of its colors. Each color has a name and an amount. If you click on the expand button of a category, its styles will show. The same thing goes for each styles.

I know a simple TreeView control would do the job if no column headings were needed, but I want to display column headings. The picture below is how I am trying to display the data:

https://social.msdn.microsoft.com/Forums/getfile/609253 (Here is a link to the picture; I can't upload an image because my account is not verified and I can't find how to verify it)

How would I achieve this kind of representation through WPF? I would be also glad if you want to suggest a better way to represent my data, but I do want to have column headings, or something similar (because some styles are named something like '101314' and you would not know it is a style name unless told).

Thank you very much for your help!

Hi to everyone,

I am developing an application with a WPF Client. This Client use the MVVM pattern.

In an UserControl the application must show some Calendars, so the user can select one or multiple dates.

For that use, I should implement some behavior that allows the user click once in a date and that date is selected (what already exists in .NET Framework) and with another click in the same date, that date is now unselected.

I've already made some searches and can't find anything useful.

This kind of behavior it is possible to implement in the Calendar Control? How exactly I do this?

Thanks for reading/helping
