How To Prevent Subsequent System Date From Being Update
Jun 11, 2006
I've design a form as such when i FIRST add a NEW
RECORD, I want the system date to be capture into the
form. I have a table calls Register. And this table
has a field "DATE" which takes the value of the system
date(=now). However, when i open the same record the
next time, the orginal value(at the time when the
record is created) of the field "DATE" will be
replaced by the new system date. However, i do not
want this to be happen because i want the field "DATE"
to take the value of the system date when i first
created the record. My question is how to prevent
subsequent system date from being updated in the
record whenever i open the same record? Thank you.

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.

I am supposed to make a database for a hotel system, how I could prevent double bookings.
My Reservation Table has the following fields:
Reservation No. (PK)
Room No. (FK)
Customer ID (FK)
Payment ID(FK)
Reservation In Date
Reservation Out Date
Together with preventing double bookings is there a way automatically that can mark in the Room Table, the status as "available" or "booked" automatically by looking at the date today?

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

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

I am developing a small application for a school. In the school they teach 5 subjects in five periods. One period's time in 40 minutes. I want to develop a table which will display the next period after previous period is over. The computer must skip to next period on the basis on system time.

I have a form where the user inputs a date into a combo box and then selects a command button.
There are two options:
1. The user can select an exiting entry (by date from the combo box) to edit a existing entry.
2. to create a new entry they enter a new date (not in the combo box).
Then the user selects a command button.
The command button has an onClick macro where the value in the combo box is checked (IsNull([Combo40]))
If the "IsNull([Combo40])" is true a message box is presented saying the date field is blank.
The problem is (finally) if you enter a new date "3/3/04" and forget to hit the enter key the system doesn't recognize the entry, in other words the "IsNull([Combo40])" evaluates to TRUE.
We currently have the msgBox remind the user to hit the enter key but that seems a little low tech. Is there anyway to look at the field and see the data even though the user forgot to hit the enter key??
Thanks

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.

I have a staff rota system that works on a rolling 4 weekly basis. I am using a table to store the shifts of a person dependent on week. I want to be able to tell access that Monday on week 1 corresponds to a certain date and then get access to figure out the rolling system based on that date.
eg Monday 21/7/13 is week 1 (7 days later it knows it is linked to week 2)
This is so if a staff member is off sick I can say they were off sick on the 24th and it will populate their timesheet with the corresponding shift without me having to input it manually. Doable?

I wrote a VBA code to get the field value of a csv file, then use it to update the database table. I paste some of my code below
Dim objConn As New ADODB.Connection
Dim objRs As New ADODB.Recordset
Dim objUpdate As ADODB.Connection
objConn.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & theFolderName & ";Extended Properties='text;HDR=Yes;FMT=Delimited'"
[Code] ....
1. The target of this code is to set the [Section] value in the table
2. The [Section] value is at the 3rd column inside the csv file
3. By using the UPDATE query, it map the [Section] value to the corresponding [Program] and [Course] in the table
This code did the job. But the problem is the string of the [Section] value is like "2-22-01". But after update to the table, the value become "2/22/2001".
The value is a string text, not date. How can I prevent this happen ?
I just attached 2 files, 1 mdb and 1 txt (change the extension to csv before test).

I am writing VBA code behind a form that used SQL SELECTS on various tables - the results of one query determine the next. I`m using the ADODB object library:
strSQL = "SELECT * FROM Table1 WHERE Field1 LIKE " & value1
objRecordSet.Open (strSQL)
Then later:
objRecordSet.Close
strSQL = "SELECT * FROM Table2 WHERE Field1 LIKE " & value2
objRecordSet.Open (strSQL)
But, when I access objRecordSet.Fields.Item(x).Value it shows the results of the first SQL statement, not the new one. I'm trying to find a way to reset the object - is there a way to do this?

I have a listbox on a form which displays data based on the value of a textbox. I requery the listbox every second or so using the timer event on the form. What I want to accomplish is that whenever the listbox changes, i.e. a new row is added to the list, a subsequent action (in my case, a beep) occurs.
I tried the afterupdate property of the listbox but that doesnt seem to work. The listbox is unbound.

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 am trying to create a user friendly form to enter a list of competitors entering an event.
I would like the user to pick from a list of events and that event to be used for subsequent records until the user changes it.
I have used a combo box to pick from a list of events but that needs to re-selected for every new record. I then added a second unbound combo box to give the main combo box its default value. It works but is not very user friendly.
