Record Lock Status & Exist Query
Feb 12, 2007
Afternoon.
I have had a search through the forum however am unable to find anything...
I have two questions:
a) How do I check whether someone else is currently accessing a record / form?
i.e. Opening the form (SchemeDetails) like this:
DoCmd.OpenForm "SchemeDetails", acNormal, "", "", acEdit, acNormal
Forms!SchemeDetails.SetFocus
DoCmd.GoToRecord acForm, "SchemeDetails", acGoTo, tempVal
Can I check if someone else is in the specified record before I open it? Record Locking is (deliberately) set to "No Locks".
b) How do I check to see if a table exists?
i.e. If DataTable2.Exists = True then ...
Or something like this?
Hope someone can help me!

I have a form and I want show a message on the form when the it is locked as another user is editing the data in a particular record.
I know the record selectors show the records lock status but it a very tiny symbol which will mean nothing to the users of the database and anyway I don't want record selector bar on the form. How I would do this???

What I've done is setfocus from another subform to this subform, and I want to add a new record. I've got my code mixed up somewhere along the line as it's saying "the command or action 'RecordsGoToNew isn't available now.I'm trying to setfocus to this form, create a new record and setfocus to a field within the focussed form.
The code I'm currently using is...
Forms!frmtopline!frmTopLineSub.SetFocus
RunCommand acCmdRecordsGoToNew
Forms!frmtopline!frmTopLineSub.Form!TransactionDat e.SetFocus

I would like help with a macro that looks to see if a record in my database table exists, then if it doesn't it adds a record with my data, but if the records does exist, it stops the routine and sends a message box to prompt if you want to continue with adding a new record.
The problem that I'm having is that my macro errors out when it doesn't find a record. I just want my macro to just see if a record exists or not. Then I can write my Iff statements based on whether it finds our or not. How do I just have my macro check for an record, then if it doesn't exist tell that it doesn't exist and not stop my macro. Is there some kind of IfExist() function or something?
Thanks for any help anyone can give me.

I'm using the following code to autofill the city and state on my form.
I can't figure out how to capture if there is no matching record in the table.
If there is no matching record, I will:
1) inform the user with a msgbox
then if the user wants
2) open a form to add the record to the table
Dim rst As DAO.Recordset
Dim db As DAO.Database
Set db = CurrentDb
Set rst = db.OpenRecordset("tblZipcodes", dbOpenTable)
rst.MoveLast
rst.MoveFirst
Do Until rst.EOF
If strZipLookup = rst!ZipCode Then
Me.txtCoCity = rst![ZipCity]
Me.cboCoSt = rst![ZipState]
End If
rst.MoveNext
Loop
rst.Close
End If
How can I capture if there is no matching record in the table?
Thanks,
Sup

I have set up a simplified event booking procedure, similar to the one generated by the access event manager wizard. It uses three tables, one with attendees details, one with the event details and abooking table that links the attendee ID with the Event ID.
The booking table uses commands similar to SELECT[Names + Contacts].[ID],[Names + Contacts].[Surname]FROM[Names + Contacts] to generate drop down lists of surnames and events so that the two can be matched together.
This works fine as a table.
However when placed into a form, whenever the form is opened I get an error message saying the record source specified on the form does not exist.
I have tried regenerating the form, etc. I have used a wizard to generate the form, closed the form, not changed anything in the database and then tried reopening it and I get the error message, can anyone shed any light?
Also if you accept the message then it knows how many records there are, so it must know there's something behind it, also if you change to design mode and then back to form mode, it finds all the data.

Dear All,
I have a MAIN table which stores the most recent info of a record with
following details:
Unique_Ref_Num|Status|Dept
1 |6 | 1
and a second table called history which records changes in the main table
HistoryID | Status | DateStamp
1 | 1 | #22/10/2007 09:00#
1 | 2 | #22/10/2007 09:01#
2 | 1 | #22/10/2007 09:05#
2 | 2 | #22/10/2007 09:06#
1 | 2 | #22/10/2007 11:00#
2 | 3 | #22/10/2007 15:00#
1 | 3 | #22/10/2007 16:00#
2 | 2 | #22/10/2007 16:10#
Where Status 1 = Open, 2 = Allocated and 3 = Closed.
----------------------------------------------------------------------------------------------
I want to get the count of number of queries which are not closed
(outstanding) at any point in time.
Example: (with a time parameter)
Input | Result
22/10/2007 17:00 | 1
22/10/2007 16:05 | 0
22/10/2007 14:00 | 2
I want to achieve this with just 1 query (not by using one query within the
other) b,coz I want to further use this query from Excel VBA (write through
Excel VBA and not store the query within Access)
Any help will be greatly appreciated

Many Thanks
Baapi

hi everyone,
just wondering if it was possible to have a box that returns the % completion of the current record depending on how much data/how many of the fields of the record have been filled out.
e.g. fields with containing data / total number of fields * 100
possible or not? if so...how is it done?
thanks, james

I have a query with a record id, report date and status.
How do I pull the latest record if the status is AA?
For latest record in report date I used Max in Totals. With just this max it is pulling the latest date for each set of records with the same record id.
This is a start now how do i pull the latest record that has a AA status?

I have a database which contains a field 'status'. This status takes a numerical value (1, 2, 3, etc...). Everything works great.
What I want is to monitor the length of time a field spends on particular status. Specifically, I want to record the length of time that the record spends with a status value of 3. So if the record has its status changed to 3, the system 'starts the clock' and once the status changes away from 3, the system 'stops the clock'. This must also continue if the status subsequently returns to 3 at a later date (for the same record) and cumulatively produce the total amount of time that the record spent on status 3.
Practical example
March 19th: Record is set to status 3 (for the first time)
March 21st: Record is set to status 1
March 25th: Record is set to status 3 (again)
March 27th: Record is set to status 2
In this scenario, I want visibility that the record has spent four days on status 3 altogether. I don't need exact times (nearest day will do). Ideally the system will only count working days (although this is not a must-have).

Hi,
I'm trying to have a button on a form that would delete a record from a table only if there are no child records linked to it.
If there are child records for the selected record, the button would be disabled.
Is there a simple way of doing this?
TIA.

I have a table that is filled based on selections that a user makes in combo boxes on a form. I am having trouble trying to figure out the best way to prevent duplicates from being inserted in the table when I do the append query part.
Since the table is filled based on the various selections the user makes I dont have a primary key or unique field.
Can someone help me figure out the best way to do this append/update queries to prevent duplicates. Also if you have a strategy for setting up some sort of unique or primary key for fields that could all be the same yet in the table only 1 record will show, no duplicates.

I have an application written in Access 2007 and packaged using the Packaging Solutions for deployment with Runtime.My problem is that I've written an updated version, and after carefully saving my original Back End away from the install site, uninstalling Runtime and the FE, installing the new FE with a blank copy of the BE having the same name and Runtime, and copying the filled BE into the same folder with the FE (replacing the linked, but empty, BE) I find that SOME of my tables in the BE are not being recognized. This isn't true of all tables. I can open some of the forms and find everything there. In other cases I get the following error message "The record source "tblName" specified on this form or report does not exist."

I currently have this set as the forms default recordsource (which works just fine):
Code:
SELECT TOP 5 tblUsers_Phone_Book.EMAIL_ADDRESS, weightedDL('me@mine.com',[EMAIL_ADDRESS]) AS Expr1
And I have this vba to dynamically switch around that email address.
Code:
Private Sub Form_Load()
Dim intPos As Integer
Dim strControlName As String
Dim strValue As String
Dim sSQL As String
If Len(Me.OpenArgs) > 0 Then
' Position of the pipe
[Code] ....
If I msgbox the sSQL - it shows identical to the default recordsource but I get the error:
The error message I get is:
Run-Time error '2580'
The record source 'SELECT TOP 5 tblUsers_Phone_Book.EMAIL_ADDRESS, weightedDL('me@mine.com',[EMAIL_ADDRESS]) AS Expr1' specified on this form or report does not exist.
I tried copying the exact working default sql into the vba and get the same result.

I have a created a database for insurance policies.
I'm using a form in the database to edit the data in the underlying table.
I use "pessimistic lock" in the database and in the form.
The database runs in a multi-user environment.
My question is the folowing:
When a user is editing a record, it is obvious that this record is set to
lock in the table (--> pessimistic lock), but the 4 records that are right before this record
are also locked too!
There is nobody else editing at that same moment in the database and it is
not a one-time occurence!
Can somebody help me out with this one... I'm realy desperite and I
searched the entire forum.

It should be noted that this is a shared database with the BE on a network. I have a process that allows users to create an Agenda for a meeting. In order to make the process more efficient the user selects a drop down box which then prefills attendees for that meeting. All very simple really, until more than one user attempts to run the process.
The issue is that this process runs a couple of queries. One to filter the attendees and then another to combine this information with the agenda information which is then finally appended to the MASTER Data tbl.
Is there a way that I can stop users using this at the same time by either giving an alert to the new users saying please wait and defer the process until the current process has completed and then the new request starts.

Hi
I have a combo box to select a record on a form.
I would like then record to lock once it is selected via the combox box and the combo box to clear.
If a records is slected again from the combo box it will then show the new record and lock it again.
The problem is users are sometimes using the mouse button to scroll and moving to a different records by accident.
Thanks

hi! I asked this question before, and i didn't understand the answer.
I have a form with a subform. at first, i disable the subform until the main form is filled completely. Then, I have a button to enable the subform. This button also disables the main form.
My first line in the subform needs to mirror the info in the main form. To do this, i open a recordset, and then use .AddNew to fill in the details.
I don't want this first line to be edit-able or delete-able once it has been filled. How do I lock it from being edited? Also, if I later decide to delete everything on the form, will i be able to clear the whole form if this line in the subform is locked?
Please helpp
