Hi Sergey

Well I declared RtlMoveMemory as:

DECLARE INTEGER RtlMoveMemory IN KERNEL32.DLL ;
  STRING hpvDest, ;
  LONG hpvSource, ;
  LONG nBytes

but I don't know if that is a correct translation. The VB code defines the parameters as ANY, ANY, and LONG respectively. But VFP does not have an ANY variable type and hpvSource is a numeric variable containing a pointer.

Then I call it like this:

bytePhrase = SPACE(500)
trtl_error = RtlMoveMemory( bytePhrase, lngStrAddress, 500 )

which shows that (a) I am missing the VarPtr() function the VB code is using and bytePhrase is not a Byte variable type which the VB code uses. Hence I get error -5 returned and bytePhrase remains empty.

All the VFP code prior to calling RtlMoveMemory() is several calls to a 3rd party DLL. All calls to this DLL return ok status and end up giving me a pointer contained in the lngStrAddress variable. The 3rd party DLL help says that at this address:

The string may contain single-byte or double-byte characters. This is why it is of type void **. The application should copy the contents into a more permanent location.


Thats really it...
