need a little bit help

[missouricity]

I need to store a FILETIME date to an fVAR and later use it to compare the value with the current date/time of a file.
I know I have convert the double number to a string to store it to the fVAR (and the other way round) but I seem to have problems with the syntax. Could someone please show me the right way?

Thanx,
shohag
