I downloaded some code from MSDN for getting the creation date of a file. Here is a piece of that code:

* DEFINEs for file share mode.
#Define FILE_SHARE_READ 1
#Define FILE_SHARE_WRITE 2

* DEFINEs for access right
#Define GENERIC_READ hex2dec("80000000")
#Define GENERIC_WRITE hex2dec("40000000")

* DEFINES for Create Mode.
#Define CREATE_NEW  1
#Define CREATE_ALWAYS 2
#Define OPEN_EXISTING 3
#Define OPEN_ALWAYS 4
#Define TRUNCATE_EXISTING 5

* File flag.
#Define FILE_ATTRIBUTE_NORMAL hex2dec("80")

Declare Integer CreateFile In kernel32 ;
	STRING lpFileName, ;
	INTEGER dwDesiredAccess, ;
	INTEGER dwShareMode, ;
	INTEGER lpSecurityAttributes, ;
	INTEGER dwCreationDisposition, ;
	INTEGER dwFlagsAndAttributes, ;
	INTEGER hTemplateFile

...

lhFileHandle = CreateFile(lcFileName, GENERIC_READ, ;
	FILE_SHARE_READ, 0, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, 0)

The CreateFile() function works in Windows XP, but fails in Windows 98 and returns Error 87 ERROR_INVALID_PARAMETER. The file in question is being accessed over a network share. I'm stumped. I couldn't find anything in the documentation or knowledgebase indicating an incompatibility with Win98. Any help would be appreciated. In the meantime, I'm going to try the outdated OpenFile() function.

Thanks.
