If you are talking about importing a .x file, then you can do the following

<MeshPrimitive3D>
  <MeshPrimitive3D.Mesh>
    <Mesh3D X3DFileSource="myfile.x" />
  </MeshPrimitive3D.Mesh>
</MeshPrimitive3D>

Deja View - the feeling that you've seen this post before.

Accessing Dynamic Binary Resources In External Assembly [modified]

Hi All,

I'm having a bit of a problem with some app styling, specifically loading an image using a DynamicResource I have this in my application window xaml:

<ImageBrush x:Name="imgLogoSmall" TileMode="None" ImageSource="{DynamicResource Logo.Default.Small}"/>

Then in my skin.dll I have:

<ImageSource x:Key="Logo.Default.Small" Source="Utils.WPFThemes.Default;component/BinaryResources/Logo/Logo_gray_orange_150x26.png"/>

ImageSouce doesn't have anything related to a uri property to set so this aboe code doesn't work at the moment ... hence this email ... I'm a bit lost on this at the moment and can't figure it out.

EDIT: Ahhh a BitMapImage instead of ImageSource might be the trick!

Any Ideas?

I don't get any errors here opening my solution in either VS2008 / VCSharp Express 2008 / Expression Blend ... can you play the file normally through WMP?

Media Element Help

C# Beginner Nick6-Jun-08 6:52

I've searched all over Codeproject, and on google, but i can't figure out how to insert a source into the Media Element from a listbox with the media file name on it.

Even though this is an extremely vague bad question, can someone help me out with this matter.

assuming your listboxitem is of type string you should do:

myMediaElement.Source = new Uri(myListBox.SelectedItem.ToString());

Don't understand the concept of strings yet, so i highly doubt it is one.

I'll try this nonetheless

could you please post the code where you are adding the source of the mp3 file to the listbox?

also if there isn't an item selected then the "SelectedItem" property will be null and in return throw the exception that you posted

EDIT:

this is how i would do it.

I'm not sure how your getting the file path, but if the filepath is a string then you would add it to the listbox like this:

string myFilePath = @"C:\myMp3\Soundgarden - Some Song.mp3";
myListBox.Items.Add(myFilePath);

then i would hook the ListBox.MouseDoubleClick. This will fire when a user doubleclicks on a song

private void myListBox_MouseDoubleClick(object sender, MouseButtonEventArgs e)
{
    if (myListBox.SelectedItems.Count > 0) //Make sure there is at least one selected item
    {
        string mySelectedFilePath = myListBox.SelectedItem.ToString();  //Get the selected file path from the listbox
        myMediaElement.Source = new Uri(mySelectedFilePath); //add it to the media element source
    }
}

Still not getting this to work out right, i figured out I'm missing the mySelectedFilePath. And if i leave as is, no song plays/it adds the same thing into the list over and over and over (if you keep selecting it)

Trying to switch things around to see if it works but still has been giving the same errors as before.

And i can't show you the code to what i had before, i switched it to see if it would work as you said you would do. Accidentally saved after changes (habit)

Hi Nick,

Its going to be really hard for anyone to help you further unless you post the code you *are* using. A string is CHARACTER based type ...

1 = numeric
"1" = string

Cheers,

Jammer

You must be adding adding the songs to the listbox in the wrong place.

Instead of switching things around to "try" to get it to work, you really need to read a good book. My Favorites are:

Pro C# 2008 and the .NET 3.5 Platform, Fourth Edition[^] - This helps understand C#

Pro WPF[^] - This is geared more for wpf.

Without any code, i have no clue on what your doing. So its real hard to help you further

Alright, I've been trying to save money for some books, but money nowadays goes by to fast.

Thanks,

And to the other guy, i changed my code to what teejayem said he would try, so what his code is, is what my code was before i tried to start over.

Jammer7-Jun-08 7:37

7-Jun-08 7:37

I've made a complete solution for you ... have a look at this to see how to do what you want.

PlayMediaElement from Listbox[^]

Change the directory in the source code to somewhere you know you have .avi files and then build it and run it ...

alternatively you could change the extension from "*.avi" to "*.mp3"

You've not picked a simple task to start with really. MediaElement is a tempramental beast!!
