Question...

[Scott Turchin]

How's that for generic?

SystemTimeToVariantTime, remember this one?


This works on my system, and with my newly found friend in Australia (Say Hi Wayne) he GPF's.
We swapped OLEAUT32.DLL'S just to test, same thing....
He uses a BYCOPY ctdate below and it works, but I don't nad it works.

Our declares are both:
DECLARE FUNCTION SystemTimeToVariantTime LIB "OLEAUT32.DLL" ALIAS "SystemTimeToVariantTime" (lpSystemTime AS SYSTEMTIME, vbtime AS DOUBLE) AS LONG

The code:

'EvalDays is how many days they are allowed To evaluate the software
'InstallDate will be In this format:
'           "MMM dd',' yyyy" "hh:mm tt"
Function IsPastExpireDate(InstallDate As String,ExpireDate As String,EvalDays As Long)Export As Long
'Dim qTimeNow        As Local Quad
Dim ctdate          As Double
Dim indate          As Double
Dim edate           As Double
Local ct            As SYSTEMTIME
Local et            As SYSTEMTIME

'-------------------
'Get Current Time
GetlocalTime ct
'Convert CurrentDate to double

GPF HERE on his PC, not mine:
SystemTimeToVariantTime ct, ctdate 'Current Time in variant format
'-------------------
If Len(ExpireDate) Then
    'Convert ExpirationDate to double
    edate = StrToVbDate(ExpireDate)
    'if todays date is bigger than the expiration date then we expired
    If ctdate > edate Then Function = %TRUE
Else
    'Convert InstallDate to double
    indate = StrToVbDate(InstallDate)
    'Compare the two dates and see If it's greater than the allowed evaluation time
    If (ctdate - indate) > EvalDays Then Function = %TRUE
End If
End Function

FIXED!!!
The solution - as Fred Oxenby discovered on October 07, 1999, the "BYVAL" in the win32api.inc declaration was wrong and should have been "BYREF"
SystemTimeToVariantTime can then be called normally, eg:
SystemTimeToVariantTime ct, ctdate

Many thanks Fred!

#COMPILE EXE "timetest.exe"
TYPE SYSTEMTIME
  wYear AS INTEGER
  wMonth AS INTEGER
  wDayOfWeek AS INTEGER
  wDay AS INTEGER
  wHour AS INTEGER
  wMinute AS INTEGER
  wSecond AS INTEGER
  wMilliseconds AS INTEGER
END TYPE
DECLARE SUB GetLocalTime LIB "KERNEL32.DLL" ALIAS "GetLocalTime" (lpSystemTime AS SYSTEMTIME)
DECLARE FUNCTION SystemTimeToVariantTime LIB "OLEAUT32.DLL" ALIAS "SystemTimeToVariantTime" (lpSystemTime AS SYSTEMTIME, [b]BYREF[/b] vbtime AS DOUBLE) AS LONG

Function PBMAIN() As Long
Dim ctdate          As Double
Local ct            As SYSTEMTIME
'Get Current Time
GetLocalTime ct
Msgbox "Current year = " & Format$(ct.wYear)
'Convert CurrentDate to double
SystemTimeToVariantTime ct, ctdate 'Current Time in variant format, GPF OCCURS HERE!
Msgbox "ctdate=" & Str$(ctdate)
End Function

check your win32api.inc date!
VbTime has to be a pointer to a double as the api will return a value in this variable.
