<A NAME="CreateProgressID">
Function <FONT COLOR="#0080A0"><B>CreateProgressID</B></FONT> As String
<BLOCKQUOTE>
Returns a unique progress ID which connects
the progress bar window with its respective upload form and script.
This method is to be called from the file containing the upload
form.
<P>
<B>Usage:</B><FONT FACE="Courier New"><P>
Set UploadProgress = Server.CreateObject("Persits.UploadProgress")<BR>
PID = "PID=" & UploadProgress.CreateProgressID()
</FONT><P>

</BLOCKQUOTE>
<A NAME="FormatProgress">
Function <FONT COLOR="#0080A0"><B>FormatProgress</B></FONT> (<I>PID</i> As String, ByRef Iteration As Variant, BarColor As String, FormatString As String) As String
<BLOCKQUOTE>
Returns HTML code for the progress indicator, including the progress bar itself
and all numeric upload parameters.
<P>
<I>PID</i> is the progress ID generated by the CreateProgressID method.
<P>
<I>Iteration</i> is an integer variable which controls how many refreshes
the progress window will stay open for in case the server stops responding.
In our code samples, this value is set to 10 and can be changed to a smaller
or larger number.
<P>
<I>BarColor</i> specifies the color of the progress bar. By default, this parameter
is set to "#00007F".
<P>
<i>FormatString</i> is a string which controls the appearance
of the progress bar. It is through this parameter that you can
customize the layout of the progress window and its components.
The format string may contain special characters
which are placeholders for various HTML tags and progress indicators.
<P>
Below is the list of possible special characters the format string may contain:
<P>
<B>%T</B> - the beginning of an HTML table (<table><tr><td>)<BR>
<B>%t</B> - the end of an HTML table (</td></tr></table>)<BR>
<B>%d</B> - a new column (</td><td>)<BR>
<B>%r</B> - a new column aligned to the right (</td><td align=right>)<BR>
<B>%c</B> - a new column aligned to the center (</td><td align=center>)<BR>
<B>%l</B> - a new row (</td></tr><tr><td>)<BR>
<B>%n</B> - a line break (<br>)<P>
<B>%B<I>n</i></B> - the progress bar; <i>n</i> indicates the number
of percentage points per progress square. Our sample uses <B>%B3</B>.
For a solid progress bar, use <B>%B0</B>.
<P>
The following special characters are placeholders for various
numeric values:
<P>
<B>%E</B> - elapsed time<BR>
<B>%R</B> - remaining time<BR>
<B>%S</B> - current transfer speed<BR>
<B>%U</B> - transferred amount<BR>
<B>%V</B> - total upload size<BR>
<B>%P</B> - percentage completed<BR>
<B>%Y</B> - remaining amount
<P>
By default, <I>FormatString</i> is set to the following value:
<P>
<B>"%TUploading files...%t%B3%T%R left (at %S/sec) %r%U/%V(%P)%l%t"</B>
<P>
which evaluates to the following progress bar layout:
