Hi

Can someone show me how to convert an __int64 into high and low order words 
for use in SetFilePointer that uses the high order word to support large 
files.

Thanks

Chris

From the Help for SetFilePointer

lpDistanceToMoveHigh
Points to the high-order word of the 64-bit distance to move. If the value 
of this parameter is NULL, SetFilePointer can operate only on files whose 
maximum size is 2^32 - 2. If this parameter is specified, the maximum file 
size is 2^64 - 2. This parameter also receives the high-order word of the 
new value of the file pointer.
