ElementFlow Intergration - FluidKit

Hey Guys,
I am having some trouble adding CoverFlow to my WPF project. I am really quiet new to WPF and Coding in general so forgive me if i say something dumb. The project is very simple, it consists of a single ListBox displaying the contents of a SQL Database using LINQ to SQL. The listbox uses a DataTemplate so that various DB fields are viewable per ListBox item. One of the DB fields is a URL to a Picture, what i would like to be able to do i display only the pictures from the DB in a CoverFlow style ListBox.

I would have no clue where to even start so any help would be greatly appreciated.

Thanks Heaps,
Alex

You can scale anything you want. Just set up a scale transform and animate it to animate your zoom.

Sure you can. Here's a sample:

<Page
  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
  <Grid>  
    <Grid.RenderTransform>
      <ScaleTransform 
      CenterX="0" 
      CenterY="0" 
      ScaleX="{Binding Value, Mode=Default, ElementName=mySlider}" 
      ScaleY="{Binding Value, Mode=Default, ElementName=mySlider}" />
    </Grid.RenderTransform>
    <Label Content="Hello" Margin="10,5,10,0" />
    <TextBlock Text="Howdy" Margin="20,20,20,10" />
    <Slider x:Name="mySlider" Minimum="1" Maximum="10" Margin="30,35,30,20" />
  </Grid>
</Page>

Basically, this sample binds the render transformation of the grid to use a scale transform, bound to the slider called mySlider in the code. It really is that simple.

Does anyone know of a *free* Windows Explorer control? I already know about the "Shell MegaPack", but that's REALLY expensive...

Hi,

I have a Silverlight application in that one page i am having 1-8 videos will present.I placed each media element in seperate canvas. I want to fullscreen one particular media element with outer canvas.

For Full screen individula video I have written the following code

private
void FullscreenChange(object sender, RoutedEventArgs e)
{
if (SLHost.Content.IsFullScreen)
{
ToolTipService.SetToolTip(fullscreen, "Full Screen");
ms1.ScaleX = c;
ms1.ScaleY = d;
SLHost.Content.IsFullScreen = false;
}
else
{
ToolTipService.SetToolTip(fullscreen, "Resize");
ms1.ScaleX = ms1.ScaleX * 5.90;
ms1.ScaleY = ms1.ScaleY * 4.10;
SLHost.Content.IsFullScreen = true;
isFullScreen = true;
flag = false;
}
}

But here I am using same full screen button to resize video.If I use like this its working properly.But I dont want to use same button for Resize if I press Escape it will go to normal stage but its not working like that if I press Escape button it will go to noraml state but the video size is not reducing to original it is in bigger size only.Can you please guide me what is the mistake i have done.If I press Escape button it has to go to normal state and also it has to reduce the video size like previous size.

Thanks in Advance

Hi,

I think full screen Escape functionality is not supported in Silverlight. But you can use double click.

When you double click video which is in full screen mode it will be back to normal size.

WPF newbe needing some helpfull advice

Ian Durward5-Jul-09 18:40

Hello. I am still a newbie in the programming world and I am about to start an IT degree at UNI. Unfortunately they don't teach any of the .net framework at any of the UNI's in my area, so because of this I have to teach myself .net. I have learnt the .net framework in the past through a different tertiary education (we call it TAFE in Australia) however they never taught us WPF.

What I am mainly looking for is advice on the following;

I want to have a main window that includes all the primary navigation controls. From this I want to have a portion of the window that contains a panel that is populated based on what navigation is selected. In the past I have done this simply by using MDI forms. I could try and recreate the MDI forms however I am looking to design applications that are more artistic and because of this I feel as though the MDI forms looks isn't as appealing.

Another way that I can think of doing it is to recreate that portion of the screen as a series of grids that contain the controls for each section and are layered over the top of each other. I can then simply show and hide the grids that a relevant to that section. The problem that I see with this approach is that, depending on the amount of sub pages, this could become a very messy form that is hard to manage. The other problem is that the code for that page will become extremely large, which I would like to try and avoid (I liked how the code for each page was kept separate in MDI forms).

So what is my best option for completing this task? I have considered pages but I am unsure on how these work and if they are a viable option. Also what if I want to do something similar to how Windows media centre does things, in which you start at 1 level and work your way down to the last level being the video? Is this all done on one form with simple show and hide or done through pages with transition effects between each level?

Any advice you can give me is greatly appreciated.

Keep an eye on my blog (link below). I have a new addition to my Ocean library that includes a ViewManager that does exactly what you are looking for. I'll also be posting a series of articles here on Code Project.

The WPF Frame control has navigation buttons if that is what you are looking for. Try Kevins Bag Of tricks samples application:

Thank you for both of your replies. I'm not too sure if these options will help me out. I think for the mean time I might go back to reading more books until I discover what I am looking for.

Also can someone explain to me what the point is for WF and will this help me solve my earlier problem, or is it simply a visual way of doing the code?

Once again thank you

WCF How to specify max and min value for a data member? [modified]

Say, if I have a data member which is string, I want to specify that its length need to be between 6 to 9 characters, or a data member is positive integer which needs to be less than 1000. Are there any attributes I can apply to data members to do this rather than validate this sort in the code?

Thanks.

Karl's exactly right. You wouldn't apply the rules on the data member because this is just a contract - it's not a business rule, because your rules may change, but your contract should remain the same. I would also add a check in your client code as well.

I think it's still useful if it's able to specify some constraints on data contracts, the reasons are the same as it in XSD. Besides, when publish those data contracts, WCF still makes use of XSD, right?

As of right now there is no native Attribute-based method of doing this. However, it is not difficult to create your own framework and set of attributes to encapsulate this behavior.

Soon (well more like next year), Microsoft will be releasing the RIA services framework for Silverlight. It includes an attribute based method of providing validation. Eventually, it will be made available for WPF.

If you have a more pressing need, this is something I've been looking into and could be convinced to accelerate my process on it. I've been a bit stagnant lately and need to get my finger on the keys (outside of work). Let's connect and I can get information on what you would need a validation framework to do and how you'd like to use it.

Does MediaPlayer support AAC format sound files?

fjparisIII5-Jul-09 13:40

5-Jul-09 13:40

Does anyone know the answer to this question? I can' find the answer anywhere. I found this information at this[^] site:

"Because of its exceptional performance and quality, Advanced Audio Coding (AAC) is at the core of the MPEG-4, 3GPP and 3GPP2 specifications and is the audio codec of choice for Internet, wireless and digital broadcast arenas. AAC provides audio encoding that compresses much more efficiently than older formats, such as MP3, yet delivers quality rivaling that of uncompressed CD audio."

Therefore it would be most surprising if MediaPlayer doesn't support this format. What are the file extensions for AAC? I haven't been able to find out that information, either.
