I am using the workbook.open method in read only mode and then converts all the chart objects in the excel file into png images. The problem is that it takes a while for excel to produce charts correctly and the script executes as soon as the file is opened, because of this the images are not the same as the actual charts and the curves are not proper.

What is the way to insert a delay in the script so that the charts are produced correctly and then they are exported into images.

Why does 9 mean SUM in SUBTOTAL?
It is because Sum is the 9th alphabetically in Average, Count, CountA, Max, Min, Product, StDev.S, StDev.P, Sum, VAR.S, VAR.P.

Hello momukhtar,
There are in fact ways to delay the execution of code in mid stream but it's probably easier
and more reliable to break this code up into two separate routines.
Look at your current Wb_Open routine and determine the point at which you want it to pause.
Then take everything you want it to do after the pause and write that as a separate sub in
a standard module. (Say you named that "WbOpenContinued")
Then in the Wb_Open, have it perform everything up to & including your "pause" point and
end that sub with:
Application.OnTime Now + TimeValue("00:00:05"), "WbOpenContinued"
just before the End Sub line.

This will allow the first part to execute (as a stand alone routine), allow the sheet(s)/chart(s) to
calculate/update and then 5 seconds later the second routine (which is actually the second
half of the original operation) will be called as its own sepatare routine.

Know what I mean?

(Obviously, you can change the TimeValue to whatever you want, but I find anything under
2 seconds to be rather unreliable due to the scan cycles of different computers, etc.)

Hope it helps.
