Hi
You may try the followign steps:

First you want to add the "Flash" control to the Toolbox:

1) Right-click on the Toolbox, choose "Add/Remove items..."

2) Select the "COM Components" tab

3) Scroll down to "Shockwave Flash Object" and make sure it's ticked

4) Click OK

5) Drag the "Shockwave Flash Object" from the toolbox onto the Form (just like any other control)
6) Righ-click on the new object and select "Properties" to show the custom properties panel.

Please note:

You may not want to hard-code the URL for the moview or file in the properties dialog, so try setting the "Movie" property to something like Application.StartupPath + "\\MyMovie.swf"
If you want to talk to the Flash movie from C# then you need to use the "SetVariable" method
If you want to talk to the host Windows Forms app from Flash, use FSCommand... you'll need to add an event handler in your Windows Forms.

Hope this helps Smile | :)

3 Approaches:

1) Use a COM object that is meant to be used for swf/flv files.
2) Use a converter to convert the swf or flv file into a XAML compliant code file.
3) Integrate a web browser into the application that navigates to the swf or flv file. Keep in mind that the end-user must have the flash player installed for it to work with the web browser control.

That's correct. It isn't set to a reference of an object. All you have done is created an array. You haven't populated it with anything.

To populate it you have to set each element with an instance of the class. For example:

it[0] = new Item();

Item[] item = { new Item(), new Item() };

This creates array with two items.

Colin Angus Mackay has given you the correct answer to your question above.

However, it's increasingly rare to need to have an array. Normally all we need is a collection in which case I'd recommend a generic list (from System.Collections.Generic).

public List<item> itemCollection = new List<item>();

You'll find that itemCollection has just about everything you'll need to manage the collection including the ToArray() method if you do need your items in an actual array.

Edit: damn these html tags screwing up the generics!

It's actually:

List<item> itemCollection = new List<item>();

I'm sure that's how you originally typed it, but you forgot to turn the pointy brackets into escaped characters. Smile | :)

I got there in the end after about 4 edits. Chris could do with the auto html tag thing having some common exclusions built in.

How filter file in WebBrowser??

You can get the text by using the WebBrowser.DocumentText property. Simply retrieve that data, liminate the stuff you want to filter, and set it back to the new version of the data.

But how do you add a URL such as "http://gmail.com" is a WebBrowser retrieves the contents of the entire page with pictures (JPG, SWF ...). And I do not want to download them.

Re: How filter file in WebBrowser??

#realJSOP6-Oct-08 3:22

Use the WebClient class to retrieve the page, massage the returned html, and set the WebBrowser.DocumentText property to the massaged URL.

using System.Net;

	string url = "http://www.mywebpage.com/";
	Uri uri = new Uri(url);
	WebClient webClient = new WebClient();
	string response = "";
	try
	{
		response = webClient.DownloadString(uri);
	}
	catch (Exception e)
	{
		if (e != null) { }
	}

	this.webBrowser1.Navigate("about:blank");
	HtmlDocument doc = this.webBrowser1.Document;
	doc.Write(string.Empty);
	this.webBrowser1.DocumentText = ProcessWebPage(response);

ProcessWebPage would be a function you write to filter the results. You gotta learn to think around problems instead of through them.

Re: How filter file in WebBrowser??

Wojciech Nagórski6-Oct-08 3:38

OK. Thank you!
But the matter is this:
[Code C #]
webBrowser1.Navigate (new Uri ( "http://gmail.com"));

HtmlDocument doc = webBrowser1.Document;

doc.GetElementById ( "Email"). setAttribute ( "value", "login");

doc.GetElementById ( "passwd"). setAttribute ( "value", "password");

doc.GetElementById ( "signIn"). InvokeMember ( "Click");

I have to move to a new address in the WebBrowser. WebBrowser must parse page. JavaScrypt process. And so to avoid manual transmission parameters POST and GET. In WebClient i must manual set parameters POST and GET. Sometime it is very difficult.

I think it is because of your ConnectionString, do you addressed your SqlDB correctly, in ConnectionString?
