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

Stephen,

Excel has always had an issue that setting up print ranges in
 Code takes F   O    R    E    V    E     R!!!

I am not sure it is a 'bug' as such, but it is well known and long standingn issue.

I suggest you take out absolutely everything except what you need to change.  Check what Excel's Defaults are and DO NOT set them again in code, only put in there the stuff that changes the default.

Add in BEFORE the code starts

Application.calculation = xlcalculationmanual
Application.screenupdating = False


If it is still super slow, email me the file offlist and I will clean up your Excel VBA code so it all runs faster.

Cheers
Darryl.

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
