((cdate("1/1/2001")+30) as task_due_date (Not working)

I have the below function written in VB, and everything works fine
EXCEPT that the sql code is not executing correctly. The date field is
in the table always shows "12/1/1899 11:59:17 PM" no other date. I'm
should have the date of the input into the function + or - the integer
in the task_due_days field.

for example (cdate("1/1/2002")+30) as task_due_date

What am I doing wrong?
Function SetTasks(trans_ id As Long, trans_type As Integer, event_date
As Date)
Dim task As String

task = "Insert into tbl_tasks
(trans_id,task_ name,Task_due_d ate,comments) SELECT (" & trans_id & ")
as trans_id,task_n ame,(cdate(" & event_date & ")+[task_due_days]) as
task_due_date,c omments FROM tbl_task_parame ter WHERE trans_type=" &

Debug.Print task

DoCmd.RunSQL (task)
End Function

the actual SQL code is.....

Insert into tbl_tasks (trans_id,task_ name,Task_due_d ate,comments)
SELECT (192) as trans_id,task_n ame,(cdate(1/1/2001)+[task_due_days]) as
task_due_date,c omments FROM tbl_task_parame ter WHERE trans_type=1

Apparently you are not using SQL Server, as there is no cdate function
in SQL Serever.

I can tell what the problem is though: 1/1/2001 = 0 with integer division,
and with floating-point division you get 0.0005. Since you got
11:59:17, I guess that in whatever you are using, you have floating-
point division. (In SQL Server you would get integer division here.)

So you need to delimit the date string. In SQL Server that would be
'1/1/2001'. But it looks a bit likely you are using Access, in which
case maybe ## is better. But you better ask in comp.databases. ms-access
it you are uncertain.

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
