Delphi, TWebBrowser, Auto-Refresh???

**alex198555** · 21-07-2010

Can I make that TWebBrowser refresh loaded URL every second or every minutes? Or specify the time when it has to refresh the URL?!

I use the below code for my Webbrowser to control it every 10 seconds, you can try to use something similar, but note that it consumes lot of resources:

Code:

mymethod() 
{ 
    WebBrowser wbmessages = new WebBrowser(); 
    Uri myuri = new Uri("http://mysite/message.aspx); 
    wbmessages.Url = myuri; 
    mypanel.Controls.Add(wbmessages); 
}

In my http://mysite/message.aspx page load event I've printed a unique value like this:

Code:

System.Guid gid = System.Guid.NewGuid(); 
Response.Write(gid.ToString());

Sorry, I am novice?

Reload the currently displayed item.

Code:

Reloads the currently displayed item.

procedure Refresh2; overload;
procedure Refresh2(var Level: OleVariant); overload;

where:-

Level is one of:

Code:

TRefreshConstants = ( 
REFRESH_NORMAL = 0, 
Default. 
REFRESH_IFEXPIRED = 1, 
Refresh only occurs if the page has expired. 
REFRESH_CONTINUE = 2, 
For WebBrowser internal use. Do not use. 
REFRESH_COMPLETELY = 3 ); 
Sends "pragma:nocache" to the server, requesting that the returned copy is refreshed and not a cached version.
