Hi,

I'm writing VBA macros and using an RTD source written in VC++.
I've got a handle on most of it, but have a few problems.


1. In my macro, I need to run a continuous loop. of the type
do while DoEvents() =
processing ...
loop

I'm able to break out of the loop successfully by using a sto
button, but the RTD data stops coming in once I'm in the loop. Why i
that, and how can I avoid that?

2. Is there a way to use a VB style timer rather than a loop? I can'
believe they omitted the timer from the control toolbox (counting of
time won't work for my purposes).

3. How can I access the classes and methods from RTD source? I hav
another Excel sheet with macros that does this, and I can't see wha
I'm doing differently. I've tried adding what I thought were th
appropriate addins, to no avail.

any help is greatly appreciated.

Thanks,
Bria
