circular calculation

[Michel T Dallaire]

Hi,

I made a component so I can use the calculator (quickcalc) from a COM component.

But from where I am, I don''t have access to the help file of the calculator.

It would be great to be able to download only the PDF or chm elp file of a component.

My quesion is, is there a way to detect a circular calculation? because when I do this, I get no error and I get false answer:

Dim g As New CalculatorVC.CalcQuickVC
g("a") = "=[b]+[c]"
g("c") = "=[a]"
g("b") = "5"

MsgBox g("a") & vbCrLf & g("b") & vbCrLf & g("c")

Result: a=250, b=5 and c=245

Where did it get the 250 and 245. It''s from a circular calculation, but no way to detect it.

Thank you.

The reason you see the values you see is that there is circular calculation limit that lets such calculations proceed a certain number of interations (the default is 100) before just returning the currently held value.

Our code base has been modified so that instead of CalcQuick just returning a value, it will optionally throw an exception that you could catch. This functionailty will be in the release version currently scheduled for Dec 16.
