Rnd Based Off System Time/date
Dec 7, 2004
Hey all,
I'm trying to find a solution to a problem. Is there any way using VBA to generate a random number, based off the current system date and time? The theory is that a random number seeded by the system date/time will be truly unique and the possiblity of it ever occuring again will be nearly nil.
Or is there a better way to create unique ID's (such as member ID's, or something similiar) based off the system date/time that can be used as a primary key in a relational db.

Hi,
I am trying to compare a value in my databse produced by the date() function, short date format, to one that is exactly 24 hours after the value recorded by the date() function. If the value in the database is 24 hours prior to the current date(), I need to flag a text box a diffrent color to alert the user. I am unsure on the If statement that I will need to produce this result.
Any help would be greatly appreciated!!!!
Thanks

I have an Access 2010 application running on Win 7 Pro which connects to a Back End SQL Server database. I am trying to get Access to synchronise the client pc system date & time with the Sql server date and time. Please note, the date/time does not necessarily have to be correct, it just has to be consistent between the server and all the pcs running the Access application.
I have tried two methods as follows. But both only work if Access with Administrator privileges, which isn't really practical.
Method 1:
Code:
Dim MyDateTime As Date
'Some Code here to get MyDateTime
If MsgBox("Change date & time to:" & vbCrLf & vbCrLf & MyDateTime & "?", vbYesNo, "Change") = vbYes Then
Date = DateValue(MyDateTime)
Time = TimeValue(MyDateTime)
End If
Method 2:
Code:
Private Type SYSTEMTIME
wYear As Integer
wMonth As Integer
wDayOfWeek As Integer
wDay As Integer
[Code] .....

I have our primary web based inventory system that I am exporting to Excel and using this as an import to Access for the main raw data for my database. This being inventory it changes daily so I am updating this table every day. When I try to append the table it ads all the records. I am wanting an easy way to add only the new records/take out the ones that are no longer there. Basically update the table with what is currently there.The only have I have found to do this is by running non-matching queries and update queries.

How do you grab a custom Fiscal Year's values based on the system clock's date?
I am building a query where I want to see the number of closed cases based on the current custom fiscal year with the system clocks date. The report that it feeds only cares about the current FY.
I need the System Clock's FY value in this query
Code:
SELECT shortname AS Station, NZ(TotalCount.TotalCases,0) AS [Cases Complete]
FROM StationList LEFT JOIN (SELECT station, count([Open Issues].ID) AS TotalCases FROM [Open Issues] WHERE [Status]="Closed" GROUP BY Station) AS TotalCount ON StationList.shortname =TotalCount.station;
Within the Query Open Issues I have the FY broken up
Code:
fiscalYear: IIf(Month([Issues].[Opened Date])>=10,"FY" & Year(DateAdd("yyyy",1,[Issues].[Opened Date])),"FY" & Year([Issues].[Opened Date]))

I had a problem. Now I decided to just make two tables, one with sales for a "passer by" and/or directly to a client without a case/labour costs. And a table for sales in relation to a case with labour costs etc. I guess I still m*ssed up on that part and have to make do with that decision (kind of like I depicted in the photoshopped image).
For invoicenumbers I want to use DDMMYYYYHHMM. When adding that field to the design of a table, how do I go about that? Do I just use a Text field and create an input mask for that? Or do I need to use a number format with a certain input mask? Or would it be wiser just to use the date/time type of field and give it a new inputmask? I guess 000000000000 would be the one for that, right? Although I read the help file I do not know if I should use ;0; behind those first group of zero's or not. Yes it is a mandatory field, but it will fill in itself as soon as a product is typed in in the product/invoice list, with a default value of the current date and time.
I need to brush up my knowledge on the formatting for that so that 28-05-1975 19:55 will be displayed and stored as 280519751955. Or is that also done automatically by using that input mask? Or will that give an error when Date or Time() etc. is used for that field in VBA?
Just a few questions I need some help with, I've been trying some stuff but it really doesn't "stick".
And if anyone has some time, I could really use some general advice/ideas for setting up the invoicing part differently for a new version of the db yet to come in the future.

Hello All...
I'm very new to Access.. so please forgive my ignorance..
Here is the scenario..
I have a table with two fields named "item" & "description" that contains 10 records total.
I have another table with 100 records with the fields "invoice #","item", "price paid","date paid","time paid".
The item fields are linked between the two, and the 100 records contain different invoices for these ten items.
I want to pull the price paid off of the latest invoice, based on the time and date... What is the easiest way to do this?
Thanks!

I have set up a form and only want to display the date and time that will appear automatically based on when the record was created. I definitely don't know how to do this.
The format that I'm looking for is: 07/24/13 11:45:44pm
From what I can see I would need two separate fields to accomplish this. I would prefer to only use one if possible. I would like to execute the value within the new record as it is entered. That date and time from that point should never change.
I will want to use the date and time in the future for quality control.

I have a weekly list of transactions that come in the format DD/MM/YYYY HH:MM:SS, I need to tag these individual transactions with a week number. The problem is, I can't use the Datepart function etc. as the day is classed as running from 8am to 8am rather than midnight. I have a list of all of the weekly date ranges for a few years (with the time) so I was able to solve this problem in excel by using the Index and Match functions. However, I'm trying to automate this process as much as possible so I'd rather perform this function in Access.

I have two tables, One table containes customer name, etc., tblcustomers the other table contains the tbltimelog, log of activity start time end time. No issues. I want to generate a form based on the dateofentry for the time record. I am not able to get a summary lets say I spent 20 hours on ABC and 20 hours on CBS. If I spent 3 different days on ABC and 6 different days on CBS it will not add them together it will list it ABC 3 times and CBS 6 times. I have tried the distinct function but it doesn't work because the date is distinct. Is there a way to do this as an SQL or whatever. Thinking I could just create a new table and calculating the totals but that seems to be a waste.

I have a form that request information from the user (StartDate, StartTime, EndDate and EndTime) the problem is that it's not working. The only way I can get any data to show is when I remove the StartTime and EndTime. Only then will it pull the items from the StartDate and EndDate.
Here is what I have as my criteria: Between [Forms]![OpPROD_ALL]![StartTime] And [Forms]![ OpPROD_ALL]![EndTime] And Between [Forms]![ OpPROD_ALL]![StartDate] And [Forms]![ OpPROD_ALL]![EndDate]
The users will be able to request a report based on a start and end date along with a start time and end time.
Side note: this is to pull date for 3rd shift (Example) 4/14/2013 10:00PM - 4/15/2013 10PM

I need to develope a system that will allow for employees to login and imput their "time card". I found one post on here about something similar, but it didn't give much info. I am very very new to Access so please give info in simple terms or very well explained. I am hoping that I can have a login and password so employees can't access eachothers time card. All it will need to track is
Date
Type of work
Hours
Rate
Comments
I am hoping that this is going to be an easy task, but I need some help. Anyone have any ideas or directions... or even better know where I could just download a template.
Thanks,

Hello buddies :D, do you have any idea how to make this work?
To select data that falls within this criteria of date range between cboDate and cboDate2 (fields on my form). The date in [tblJobDetails]![timeIn] come in this format "08/17/06 10:24 AM", but the cboDate/cboDate2 (takes in date only e.g 08/17/06) what i am after is to evaluate specific hard coded time in addition to the date entered, i.e. even tho, i haven't entered time on the cboDate/cboDate2, I want specific time hard coded where e.g If i select a date range of 08/17/06 and 08/18/06 on my cboDate and cboDate2 it should really be evaluating: 08/17/06 8:00 AM to 08/18/06 8:00 AM.
This is the criteria i curentlly have on my query in design view tha works perfect in selecting date only.
([tblJobDetails]![timeIn]>=[Forms]![frmPendingJobs]![cboDate] Or [tblJobDetails]![timeIn]>=[Forms]![frmPendingJobs]![cboDate] Is Null) And ([tblJobDetails]![timeIn]<=[Forms]![frmPendingJobs]![cboDate2] Or [tblJobDetails]![timeIn]<=[Forms]![frmPendingJobs]![cboDate2] Is Null)
How can I incorporate 8:00am to 8:00am into my cboDate and cboDate2. What can i do to make this happen? Your kindness will be greatly appreciated http://www.naijaryders.com/forums/images/smilies/thankyou.gif

I need a query run that brings up a list of customers that need maintence after 6 months after their last maintence service. As soon as you open the DB, the event/query runs and if there are any customers past due to display them. And if there are none, to not even show the query at all.
I have very little experience with timers and if/then statements and don't know how to set this up.
Any help would be greatly appreciated. Thanks in advance.

I have a database with date and time each stored in a separate field. Now I want to query the database based on a start date/time and an end date/time. I started with the code below but it only returns events within the same time range on each day when what I really need is every event from a specified date and time through a specified date and time.
SELECT myTable.ID AS myTable_ID, myDate, myTime, FirstName, LastName
FROM Staff INNER JOIN myTable ON
Staff.ID = myTable.StaffID
WHERE myTable.myDate >= #3/2/2014#
AND myTable.myDate <= #3/3/2014#
AND myTable.myTime >= #8:00PM#
AND myTable.myTime <= #11:00PM#
ORDER BY myDate desc
In the above example what I want is every event from 3/2/2014 8:00PM until 3/3/2014 11:00PM. But what I get instead is every event between 8:00PM and 11:00PM on 3/2/2014 and every event between 8:00PM and 11:00PM on 3/3/2014.

I wanted to assign the field "Number of magazine" with special format based on date/time format but showing only year and month in the format: "yyyy-mm".
So in property of this field in format I put yyyy-mm and in input mask I type 0000-00;;-
I also created the form based on the table containing above field and I defined format and input mask for corresponding formant in the same way like at the table.
But if I try to type date for example 2014-01 in text box of the form it comes up with the full date 2014-01-01. Why does it do like this? What do I do incorrectly?

hi guys,I want to group a field in my query within a certain period of time, say 1 week. (e.g. between #12/5/2005# and #12/11/2005 23:00:00#) however I need to run this query every week.so I don't want to have to change the dates every week just to run the query.Is there a way to use the system's calendar date so that the values will be input automatically (i.e. to group between today and today-6 23:00:00)?? maybe using date() function or something??:confused: heaps n heaps of thx!!:D
