it going &#8211; I am using
it in exactly the same setup (VB6 and XP) and it seems to work fine so I
shall
be interested in how you get along.</span></font></p>

<p class="MsoNormal"><font size="2"

OCX sends xAP messages is
slightly different to the published v1.2 spec. Patrick is going to revise
the OCX
shortly to bring it inline. The resulting messages work well with
Patricks&#8217;
other stuff but Stuarts&#8217; Framework is a little tighter on the
control of message
structure and balks at the xAP messages from the OCX

lack of a CHR(10) after the xAP header line and also after the section

can massage them into full compliance with the following code snippet

it&#8217;s not the most elegant but it was a quick fix. Your xAPp will
