[AccessD] Building a spreadsheet from Access ... slow segment of code

Stephen,

  You using early or late binding?  While late binding does get you around
reference issues, it does carry a performance penalty.  If your doing lots
of operations with OLE Automation, it may be worth the references hassle to
use early binding.

Jim.

Subject: [AccessD] Building a spreadsheet from Access ... slow segment of
code

The code segment below takes around 10 seconds to run.  The worksheet
has been just created in code, an embedded chart has been built on the
worksheet (again, code), and the code below is the 'prettying up' bit.
Yep, to get it, I recorded a macro in Excel and then commented out the
bits I didn't want/didn't work.
 
I put some rudimentary time checks at random places in this segment.
Embedded in the sample, I have put the elapsed time it took to get to
the indicated line.
 
Any ideas?  The rest of it runs really fast on a 6-year-old PC (768MB,
WinXP SP2, Processor x86 Family 6 Model 8 Stepping 0 AuthenticAMD ~1529
Mhz) but I can't see why this is happening.  I am generating a couple of
hundred sheets at a time, so the slowness is not trivial.
 
TIA
 
Stephen Bond
