George,
We have a success on our hands, what you have to do is convert all the type long fields in the struct to a string, and obtain a pointer to ( using the pointer classes in my case ) the string fields, concatenate the fields and you're in business. I enclose a sample VFP program for your observation

&& Sample Fox program ( very rough ) of using the SHFileOperation API

&& This program assumes you've got ( and registered ) Vlad Tatavu's pointers.ocx

SET CLASSLIB TO ("c:\pete\api pointer classes\pointers.vcx")
oPointers = CREATEOBJECT("Pointers.pointersctrl1")

declare integer GetActiveWindow in win32api
declare long SHFileOperation in shell32 string @

hwnd = oPointers.Converter.NumberToInteger4String(GetActiveWindow())
wFunc = oPointers.Converter.NumberToInteger4String(0x3)
pFrom = oPointers.GetPointer("c:\pkcopy\*.*" + chr(0) + chr(0))
pTo = oPointers.GetPointer("c:\temp")
fFlags = oPointers.Converter.NumberToInteger4String(0x80)
fAnyOperationsAborted = repl(chr(0),4)
hNameMappings = repl(chr(0),4)
lpszProgressTitle = oPointers.GetPointer("Peters Test")

fileop = hwnd+ wFunc + pFrom + ;
pTo + fFlags + fAnyOperationsAborted ;
+ hNameMappings + lpszProgressTitle

result = SHFileOperation(@fileop)

return(result)
