VFP Function to determine file size.

by  EzLogic  Posted    (Edited  )
* Example of use:
* nSize = GetFileSize("C:\SomeFile.Ext")
* Returns:
* -2 if the file name is not passed
* -1 if the file passed as param was not found
* FileSize in Bytes

*********************
FUNCTION GetFileSize
PARAMETERS gcFileName && File to be checked
PRIVATE pnHandle,pnSize
IF PARAMETERS( ) = 0
RETURN -2 && Return -2 if no parameter passed
ELSE
IF !FILE(gcFileName)
RETURN -1 && Return -1 if file does not exist
ENDIF
ENDIF
pnHandle = FOPEN(gcFileName) && Open file
pnSize = FSEEK(pnHandle,0,2) && Determine file size, assign to pnSize
=FCLOSE(pnHandle) && Close file
RETURN pnSize && Return value

*********
Another way of doing it (Thanks for Baltman for the tip)
** I haven't tested it, I assume he had
?SizeArray(adir(SizeArray,"C:\SomeFile.Ext")+1)
