Question

I have an Excel macro that takes an exceedingly long time. It seems to crash Excel (I get a Not Responding message in the taskbar) when I leave it unattended, but if I put a breakpoint that gets hit every five or ten seconds, it’s OK. Trouble is, I’ll need to step on from the breakpoint about a quarter of a million times (we’re looking at about 200 hours to execute this beast)

I’m guessing that the absence of message pump activity is antagonising the kernel, so how might I flush the message queue? Or am I barking up the wrong tree entirely?

I’m very new to this, by the way, so documentation references will be very welcome.

Cheers,
Guy

Seconding the opinion that 200h is a bit worrying, however you can try the DoEvents statement which “surrenders execution of the macro so that the operating system can process other events“. (Note that calling DoEvents has an additional time penalty)
