Stack Overflow

Does anyone know what a stack overflow error is on a PC.My small database and calculation program appears to be causing pc's to blue screen with a stack overflow error,even if the program is not open.

Stack overflow is where you try and place more items on a stack than there is allocated memory for. It's usually not a problem, unless you have a lot of recursive functions.

Have you tried running it through the debugger to watch the call trace stack?

couldn't work out "call trace stack" ???

It's explained in the documentation

I don't have VB installed anymore, but I'm sure there's a dockable window you can open that shows all the called functions. For example, in the following code:

Sub X()
    Dim x as long
    x = another(5)
End Sub
Function another(byval thething as long) as long
    another = thething * further(thething)
end function
function further(byval evenmore as long) as long
    further = evenmore + 1
end function

If it dies in further, then the call trace stack would show something like:

further
another
X
