Can you try this
public void functionToNavigate()
{

object oMissing = null;

HTMLDocumentClass objects=new HTMLDocumentClass();

axWebBrowser1.Navigate(URL,ref oMissing,ref oMissing,ref oMissing,ref oMissing);

while(axWebBrowser1.Busy)

{

Application.DoEvents();

}
objects=(HTMLDocumentClass)axWebBrowser1.Document;

}

private void axWebBrowser1_Enter(object sender, System.EventArgs e)
{

}

Why you are getting this error any idea ?

				myHttpWebRequest.Proxy = myProxy;<br />
				Uri siteUri = new Uri(webPageObject.Url);<br />
				c = new Cookie("chasezip",_wholeZipCode, "/", ".chase.com");<br />
				c2 = new Cookie("marketlist",webPageObject.MarketList, "/", ".chase.com");<br />
			<br />
				myHttpWebRequest.CookieContainer = new CookieContainer();<br />
				<br />
				CookieCollection cookiesBefore= myHttpWebRequest.CookieContainer.GetCookies(siteUri);<br />
				<br />
				myHttpWebRequest.CookieContainer.Add(siteUri, c);<br />
				myHttpWebRequest.CookieContainer.Add(siteUri, c2);<br />
				<br />
				CookieCollection cookiesAfter= myHttpWebRequest.CookieContainer.GetCookies(siteUri);<br />
				<br />
				<br />
				<br />
									<br />
				response = (HttpWebResponse)myHttpWebRequest.GetResponse();<br />
				resStream = response.GetResponseStream();<br />

I have this message of error when I run my app with a server and a client and I have serializable objects.

An unhandled exception of type
'System.Runtime.Serialization.SerializationException' occured

Additional information :
Because of security of restriction, the type

System.Runtime.Remoting>ObjRef cannot be accessed.

This is a restriction with remoting and serialization I'm assuming.

It is caused because you need to alter the typeFilterLevel settings from their default to "Full"

Below is an example of the App.Config section. You can do this in code too, just search for typefilterlevel.

<serverProviders>
  <formatter ref="binary" typeFilterLevel="Full" />
</serverProviders>

Hope that helps

Where I can change this setting? Where is App.Config.

[PermissionSet(SecurityAction.Demand, Name = "FullTrust")]

I put that before my class on the server who make the serialization.

And still doesn't work

OK since you do not have an App.config file you must have some code that sets up the remoting below is an example of how to set the typeFilterLevel in code provided by microsoft and reproduced here for convenience:

// Creating a custom formatter for a TcpChannel sink chain.
BinaryServerFormatterSinkProvider provider = new BinaryServerFormatterSinkProvider();
provider.TypeFilterLevel = TypeFilterLevel.Full;
// Creating the IDictionary to set the port on the channel instance.
IDictionary props = new Hashtable();
props["port"] = 8085;
// Pass the properties for the port setting and the server provider in the server chain argument. (Client remains null here.)
TcpChannel chan = new TcpChannel(props, null, provider);

form logic/timing

How do I get my label to update on the form before my program enters the function? currently the form does not update until the download function hits a message box that is in it.
String stime = DateTime.Now.ToString();
lblStartDisplay.Text = stime;
Download();

Can you explain more thoroughly what you need to achieve?

Re: form logic/timing

Stefan Troschuetz8-Feb-07 1:43

The following should do the trick:

String stime = DateTime.Now.ToString();
lblStartDisplay.Text = stime;
lblStartDisplay.Refresh();
Download();

Hi i am building an xml file to use in my app but the links in the xml file need to be encoded using the Server.URLEncode() function but as the file is being built in a seperate class that class does not have access to the Server.URLEncode() function, so im basically looking for advice as to how i would work around this any help appreciated
Thanks in advance

Use the static HttpUtility.UrlEncode method.

Why do you think that the links need to be url encoded?

Byte Array question

Planker8-Feb-07 1:22

8-Feb-07 1:22

I am downloading a file and using the function below to read data from the site. It seems that the file downloads a little faster through firefox but not much, is there a better way to download the file? Can I increase the size of my Byte Array?

private void CopyData(Stream FromStream, Stream ToStream)
{
// This routine copies content from one stream to another, regardless
// of the media represented by the stream.
// This will track the # bytes read from the FromStream
int intBytesRead;
// The maximum size of each read
const int intSize = 4096;
Byte[] bytes = new Byte[intSize];
// Read the first bit of content, then write and read all the content
// From the FromStream to the ToStream.
intBytesRead = FromStream.Read(bytes, 0, intSize);

while (intBytesRead > 0)
{
ToStream.Write(bytes, 0, intBytesRead);
intBytesRead = FromStream.Read(bytes, 0, intSize);
}

}

Download speed is dependent on many factors, you code only being one of them and most likely not the problem.

Why not use the Response.OutputStream method? Or if you use framework 2.0, you can use the Response.TransmitFile method.
