I am trying to find out the proper way to use the "write_disk_file" proc. Here is the following code. When I assemble it I get error A2206: missing operator in expression.

Do you have any idea how to fix this or where to find an example?
You left a comma out of your invoke statement:
invoke write_disk_file, fnstrgPointer, bufferPointer, maxp1
Dan,
Forget what I said here before, I'm still in shell shock learning Windows 7.
Dave.
Adding a comma works great. When I add the code to put data in the buffer it works just the way I want. My program must work with "stralloc maxp1" because it work with a very large buffer: 268,410,876 bytes
Where do you get this stralloc stuff? 268 MB is no problem for a simple HeapAlloc...
include \masm32\include\masm32rt.inc
.code
start:
invoke HeapAlloc, rv(GetProcessHeap), HEAP_GENERATE_EXCEPTIONS, 800000000
xchg eax, edi
.if eax
print str$(edi), 9, "is the pointer", 13, 10
invoke HeapFree, rv(GetProcessHeap), 0, edi
inkey str$(eax), 9, "retval HeapFree", 13, 10
.else
inkey LastError$()
.endif
exit
end start
OLE string works fine. :biggrin:
