VBA macro running slow/crashing when autofilling with a UDF

Hi,


I need to a turnaround today if possible please. Thanks in advance.


I have a file that runs a macro, the macro is taking far too long to execute. However, if I step through the macro it works as quickly as it should stepping through.


It slows down once it hits the Autofill part of the "TimeAnalysis" macro, it is basically entering a formula into the cell (formula is from a UDF I have written), it then copies it down. I've tried numerous different ways to perform this including .formula etc...


Below is the macro code and the function code is below that. It is on a file of approximately 900 rows.


Regards,


Ash

I read about this, but why would it crash it out? Also if I do a formula in J2 and manually autofill it within Excel, it works fine, as soon as I automate the process it trips up. Is there any way around this or any alternative solutions you could help me with?

Ash

Sorry but I really can't help without having the actual data and being able to run and debug the code.

Okay, is there any way I can post the file here or do you have an email you can PM me? It'd be really appreciated.

Can confirm crashing after filling in the so-called G_Distance formula.
I've got a very simple macro that takes two postal codes and city names and adds the G_Distance formula (Google Distance) in an adjacent cell.
All goes well until I have filled in about 50 to 100 distances, then Excel crashes and there is only Ctrl-Alt-Del to get out of it.

I build in a loop to save every 10 instances so that at least I have the latest results instead of losing everything.
I tried several things, including adding some Wait or Sleep, but it crashes every time...

Have you tried writing the equations in for each line rather than doing an autofill down.
This method also uses variant array which means it only writes to the spreadsheet once which will be much faster. Note I not sure whether I have modified your equation correctly because i can't test it but it shows you how to do it.
Code: 
ReDim outarr(1 To LR + 1, 1 To 1)

    i = 3
    For i = 3 To LR + 1
      outarr(i, 1) = "=IF(N" & i & "=1,""N/A - First Client"",IF(N" & i & " =COUNTIF($A$2:A" & LR & ",A" & i & "),""N/A - Last Client"",IF(F" & i & "="""",""Error - No transport mode present"",IF(TRIM(F" & i & ")=""Driver"",G_TIMEDRIVE(E" & i & ",E" & i & ",""Decimal"")*60,IF(TRIM(F" & i & ")=""Public Transport"",G_TIMEPUBLIC(E" & i - 1 & ",E" & i & ",""Decimal"")*60,IF(TRIM(F" & i & ")=""Walker"",G_TIMEWALK(E" & i - 1 & ",E" & i & ",""Decimal"")*60))))))"
    Next i
    Range("J1:J" & LR + 1).Formula = outarr

Yes I do. After each line I even wait for 3 seconds to give the google formula the chance to find a solution, otherwise I get a lot of zeroes.

The solution I was proposing only writes to the worksheet once and does all the lines in one go, so you would only need to wait after the macro has finished for the google function to come up with the goods

I do wonder whether the way you are trying to do this with accessing the Google internet facilities using a function is the best way rather than directly within VBA where you have much more control of what is happening
