No, the install shield part has been outsourced to another country; communication with them is done using Lotus Notes.
And on the top of it, John forgot to mention the legacy VB6 library used in a part of his code that has also to be maintained.

That's the problem with big frameworks. You get them to work but most of the times you don't fully understand why and how they are working. This produces, in the best scenario, a slow application, in the worst an application with many subtle reliability defects.

Using a resource in multiple places

Hi
I have a rather simple question. If I declare a ModelVisual3D as a resource in XAML, how can I use this resource in multiple places without getting the error " Specified Visual is already a child of another Visual or the root of a CompositionTarget" ?

In your resource file, use the Shared attribute so your resource gets cloned each time you use it.

For example:

<ModelVisual3D x:Shared="False" ...>
   ...
</ModelVisual3D>

I can't access this attribute at all?? I tried "Shared, x:Shared, isShared" and none of them exist. Do I have to reference something specific first?

This only works if your item is defined in a ResourceDictionary.

Okay thanks I got it working.
For some or other reason x:Shared doesn't show up in intellisense, but it still works.

Upload Images to SQL database in silverlight

Hi,

I am trying to implement upload images to database by using a WCF service.First I placed a opendialogbox in the silverlight page and I am planning to to pass the file path to the WCF service and there I will convert it to binary format and save it in the database. Here my problem is, I am unable to get the openfile dialog file complete path due to security reason in silver light and in WCF service I an not even getting open dialog control.

If anyone have idea to get the complete path of the selected file in open file dialog please reply me.

Thanks in advance.

You can't get the complete path because this would represent a security hole in the system. It's the same reason that you don't get the path in the standard file upload component in ASP.NET. By giving access to this, you could present a malicious author with knowledge about your file system.

Read file as stream from openFileDialog.File from the client and send it to the WCF Service.From the WCF Service write the stream in server and save that path in database.

Usercontrol properties

Hi,

I developed a Usercontrol which has a slidercontrol and the textbox displaying the current slider value.

I need to adjust only the slider width from the widow XAML that uses the Usercontrol . Can anyone let me know how to achieve this.

Thanks

Hi...

An example in the Codeproject has this implementation.

I am extracting from it and pasting it here.
in XAML.cs,

<pre>      private void CenteringSlider_LostMouseCapture(object sender, MouseEventArgs e)
            {
                  // change the size of the ellipse when slider value is change
                  // for this example the slider max is 80
                  // and the slider min is -80

                  PlumEllipse.Width = PlumEllipse.Height = (100 + e.NewValue);

            }

            private void CenteringSlider_ValueChanged(object sender, RoutedPropertyChangedEventArgs<double> e)
            {
                  // set a 500ms duration
                  Duration returnToCenterDuration = new Duration(new TimeSpan(0, 0, 0, 0, 500));
                  CenteringSlider.BeginAnimation(Slider.ValueProperty,
                        new DoubleAnimation(CenteringSlider.Value, 0, returnToCenterDuration, FillBehavior.Stop));

                  // set the slider value to zero
                  //   otherwise the slider will return to the last postion after the animation
                  CenteringSlider.Value = 0;

            }
</pre>

Please search for the full project in codeproject itself.
Thank you,

Assuming you have exposed a property in your usercontrol for the width, all you need to do in the control itself is add Width="{Binding MyWidthProperty}" in the XAML for the slider. Then, the hosting item just sets MyWidthProperty="nnn" (where nnn is the width you want).

Thanks for the reply , should i expose the width as the dependency property.

One more question, if i need to modify other properties like Height, MinWidth,MinHeight then should i register those properties also as a dependency property in the user control.

Thanks

I am looking for a variation of this answer as well (assuming I read the question right).

I have a simple UserControl that has 3 controls which I plan to use to standardise the visual look. The only part of this control that will very is the text on the button. I would like to be able to set this within the XAML as once set it will not change.

For example, i would like to be able to do something like this.

<Views:CurrentStatusView ButtonText="Proceed"/>

If I expose a property I am able to set the value, but how do I use this within the user control, I have tried Binding, setting the value in the constructor etc with no success.

Many thanks

Here's a sample that shows how to do this (first of all, the XAML):

<UserControl
	xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
	xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
	xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
	xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
	mc:Ignorable="d"
	x:Class="WpfSample.CurrentStatusView"
	x:Name="UserControl"
	d:DesignWidth="640" d:DesignHeight="480">

	<Grid x:Name="LayoutRoot">
		<Button HorizontalAlignment="Left" VerticalAlignment="Top" Content="{Binding ButtonText}"/>
	</Grid>
</UserControl>

then the code behind

using System;
using System.Collections.Generic;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using System.ComponentModel;

namespace WpfSample
{
  /// <summary>
  /// Interaction logic for CurrentStatusView.xaml
  /// </summary>
  public partial class CurrentStatusView : UserControl
  {
    public CurrentStatusView()
    {
      this.InitializeComponent();
      ButtonText = "Hello there";
      DataContext = this;
    }

    public static DependencyProperty ButtonTextProperty = 
      DependencyProperty.Register(
        "ButtonText", 
        typeof(string), 
        typeof(CurrentStatusView));
    public string ButtonText
    {
      get { return GetValue(ButtonTextProperty).ToString(); }
      set { SetValue(ButtonTextProperty, value); }
    }
  }
}

Finally, you set it with:

<WpfSample:CurrentStatusView ButtonText="Howdy" HorizontalAlignment="Left" Margin="27,42,0,0" VerticalAlignment="Top" />

Obviously you are trying to swallow more than you can chew.
You really do need to spend a minimum time learning the little tiny block of which a WPF application is made.
Stress to your boss that you need a learning phase (such as 1 week reading CP articles and experimenting) and it's not wasted as you are just unable to be productive yet!
