Remarks
MemCopyString() copies the specified number of bytes from the source memory buffer to the destination memory buffer.
If portions of memory occupied by the source string overlap with portions in the destination, the overlapping region is overwritten.
If the number of bytes in the source memory buffer is less than
dwCount, the rest of the destination memory buffer is filled with blanks.
Use MemMove() to copy overlapping regions before they are overwritten.
