Here's an odd one:
Today, in my VFP 9 SP1 production .exe, my error logger reported VFP
Error 11 ("Function argument value, type, or count is invalid.") on
a call from a form like this:
MyForm.MyMethod:
BooleanResult =
oMyObject.Method(THISFORM,"specifictablename",oMyOtherObject.Method("fieldname"))
** end method**
This system has been in operation since late 2007. I normally have
zero problems passing methods as parameters to other methods, so
this surprised me.
You do not pass a method above. There being no method type in
VFP, you can not do it. What you are passing as the third parameter
to oMyObject.Method is the return value from a method call.
The data types of the passed variables are not really relevant:
Toss that assumption. The error message states that something
of the sort may be it.
With not much to go on, I suggest that you examine each of the
items in the statement to see that they really are what you think
they are. Something may have been overwritten. In particular, start
by checking that oMyObject and oMyOtherObject are of type object,
that neither is .null., and that each refers to the correct class.

Is passing a method as a parameter to another method an official no-no in VFP?
It is impossible, and you are labelling something else as it.
