progress bar

Question

i have made a web browser and i wont to ad a progress bar to it to show the progress tho loading a web page can any one help

thanks

Answer 1

Do you know how to use a progressbar?  It needs a maximum value, and a current value.

The WebBrowser control has an event, ProgressChanged.  It uses a custom EventArgs class, WebBrowserProgressChangedEventArgs.  (Clever name, huh.)  That class has two properties.

public long CurrentProgress { get; }

Member of System.Windows.Forms.WebBrowserProgressChangedEventArgs

Summary:

Gets the number of bytes that have been downloaded.

Returns:

The number of bytes that have been loaded.

..and...

public long MaximumProgress { get; }

Member of System.Windows.Forms.WebBrowserProgressChangedEventArgs

Summary:

Gets the total number of bytes in the document being loaded.

Returns:

The total number of bytes to be loaded.
