Download Files From Web With Progressbar

[S-One]

Also there are some ! according to VB with the default project. (I am now using an exact copy of webfiledownloader.vb in my program)

Warning 1 Variable 'FS' is used before it has been assigned a value. A null reference exception could result at runtime. I:\Documents and Settings\Sebas\Mijn documenten\Visual Studio 2005\Projects\FileTransfer\FileTransfer\WebFileDownloader.vb 70 21 FileTransfer

Warning 2 Function 'FormatFileSize' doesn't return a value on all code paths. A null reference exception could occur at run time when the result is used. I:\Documents and Settings\Sebas\Mijn documenten\Visual Studio 2005\Projects\FileTransfer\FileTransfer\WebFileDownloader.vb 99 5 FileTransfer

Hmm, i have converter my project from .net 2003 to 2005 and i also get this Warning, weird, but there is return

also i get warning abour DialogResult.no, yes, or whatever is used...
i have resolved this with

System.Windows.Forms.DialogResult....

EDIT:
ok i have resolved FormatFileSize Warning Case else is missing:

                Select Case Size / KB
                    Case Is < 1000
                        Return (Size / KB).ToString("N") & "KB"
                    Case Is < 1000000
                        Return (Size / MB).ToString("N") & "MB"
                    Case Is < 10000000
                        Return (Size / MB / KB).ToString("N") & "GB"
                    Case Else
                        Return Size.ToString & "bytes"
                End Select

Size.ToString("D") .ToString("N")
