This function I am mainly used to copy the binding of memory addresses and string variables. Do a memory file mapping, and then different processes can directly access memory by using string name variables. Here, the safe array and pointer methods are used.

how to read string from memory by pointer for CreateFileMapping?
http://www.vbforums.com/showthread.p...ateFileMapping
dim ptrstr1 as string '* ptr
dim lenarr() as long '* ptr
dim strarr() as long *100 '* ptr +4
so I can use:
write string:
lenarr(0)=lenb(s)
strrarr(0)=s

readstring from filemapping(memory):
msgbox ptrstr1

it's a way to read/write memory without api calling for run quickly。
it's used for share variable to more process.
write abc.exe "dim ptrstr1 as string",read from abc2.exe by ptrstr1。
Just as multiple threads can access global variables in a process, we now implement global variables for multiple processes. .
