I got the following error "Ole error code 0x80010105: The server threw an exception" during the save as html session.

The main coding I'm using
#define wdFileSaveAs 100

oWord=CreateObject("word.Application")
oWord.FileOpen(NAMES) &&open the file

oWord.FileSaveAs(NAMES,wdFileSaveAs,.f.)

Can anybody help me with the right coding to save as html file?
