Hi,
I am working on a silver light application. In this I need to upload videos, save them in afolder and retrieve them back to display. In this I need to save the uploaded video in a folder for retrieving later.
I came across some applications where the video is converted to bytes and saved in database and retrieved from there. But as i want the video to be saved in a folder I need to convert the byte[] in to video in a service and save itin my application folder.
If any one have any idea to directly save the slected file in the openfiledialog to a folder or to convert byte[]to video and save it in a folder, please rply me.
Thanks in advance

What part of this are you having problems with?
The System.IO Namespace[^] should have everything you need

I've been learning c# for about 2 months now and have already made some pretty useful winform applications. With that said I feel that I have a decent understanding of c# although there is still plenty to learn. I'm at the point now where I find myself wanting to experiment with custom controls. At this point I'm not sure if I should continue to learn WinForm's or shift my focus on WPF as it seems to be the emerging tech.
Any advice would be great.
Thanks!

WPF is gaining foothold, I suspect more and more apps will use winforms in the future. Have you learned proper C#, things like different container classes, how to handle objects that are IDisposable, etc ? If not, I'd stick to winforms while learning the language a little better. Then I'd look into WPF.

i totally think you shoud turn to the WPF,as we know,some parts of the VS2010 is designed by WPF,so i think the microsoft will think highly of the WPF,and wo know the route MFC->WinForms->WPF.so we shoud learn the new tech~
sorry,my english is poor --!

thanks for the feed back I've already stared investigating WPF, pretty interesting so far. I'm using VS10 beta and it seems much better than express edition. I think I'm going to bite the bullet and purchase the standard edition when it come out.

WinForm will be replaced by WPF sooner or later. WPF is suitable for programing under Win7 or Vista OS.

So are WinForms - you need to define the reasons where WPF is superior to WinForms in order to convince people to use it.

Hi,
I am developing a WPF UI application .
I have a menu on top of the screen, which has File, Help menuitems.
In file -> Backend features (shortcut key is ctrl + B), Exit (Ctrl + x) sub menu items.
when clicked on any sub menu item, the corresponding window opens.
So, with out using mouse, by pressing ctrl + B or Ctrl + x, how can the window be opened??
Also, how can I display a small line below the "F" in the File so that when user presses Alt + F, the File menu should be visible.
I am working on WPF using C#.
Please guide me.
Thanks
Ramm

I would just handle the key press event, I'm not sure how to do shortcuts in WPF on the menu, if autocomplete and MSDN doesn't tell you, just handle the keypress directly

Try something like this,
<Menu DockPanel.Dock="Top">
<MenuItem Header="_File">
<MenuItem Header="Exit" InputGestureText="Ctrl+X">
</MenuItem>
</MenuItem>
</Menu>
And look at this[^] and this[^] for the CommandBinding option

Is there a property or style for the selection color? I use the VS2008.

I'm having the same problem on mine. I've even added a ClientAccessPolicy.xml file to the root of the website. This problem isn't plaguing me when running from localhost, but it is a problem on my test site. I'm thinking it's something to do with the cross domain security policy file, but I'm stuck there.

I copied the file under there to my directory and I'm still getting the same error. Is there something special that needs to be done for a Windows XP machine to be able to host WCF services in IIS?

Have u hosted WCF in IIS?Then copy that crossdomain.xml to intepub>wwwroot.
Hope this will solve your problem.

Hi,
I am working on Silverlight application in this I have to upload and display the images. I implemented this using silverlight service give below. THis worked fine for small size images and for images(memory size greaterthan 60KB) it is giving me exception as
"System.Reflection.TargetInvocationException"
"An exception occurred during the operation, making the result invalid. Check InnerException for exception details."
While debuging it is not even entering in to the WCF service. The control is directly passed to the Display Results method
I anyone know any solution to upload images of any size from a silverlight application please reply me.
Method in WCF service:
public List<AdImages> GetImages(byte[] imageData,string ImagePath )
{
----------Code to save images----------
}
public class AdImages
{
public byte[] ImgData { get; set; }
}
Calling service from silverlight application
Service1Client Img = new Service1Client();
Img.GetImagesAsync(fileBytes, ofd.File.Name);
Img.GetImagesCompleted += new EventHandler<GetImagesCompletedEventArgs>(DisplayResults);
Display results method:
void DisplayResults(object sender, GetImagesCompletedEventArgs e)
{
---------code to convert bytes to image and assign it to a image control---------
}
Thanks in advance.
