Determining Appropriate Const MaxRecords
Jun 7, 2005
I have an ASP / Access storefront, connecting through JET OLE, which is frequently crashing with '800040005 System Resource Exceeded'. The whole ODBC/Jet service must be restarted by my host manually.
Usually this error indicates an unclosed rs.open. I have however triple checked all code and there are no unclosed loops.
I am examining the basic connection variables and wondering if perhaps as my database has grown over the last year, the following original 'out of the box' settings are no longer suitable, and causing this error.. in particular maybe the 'Const MaxRecords' is no longer enough (or is too many?). How does one calculate what these Const settings should be?
Thanks for any help!
Code:Response.Buffer = TrueConst adEditAdd = 2Const adCmdText = 1Const adCmdTable = 2Const adOpenForwardOnly = 0Const adOpenKeyset = 1Const adOpenDynamic = 2Const adOpenStatic = 3Const adUseClient = 3Const adLockPessimistic = 2Const adLockOptimistic = 3Const maxRecords = 200

I have an .adp file but I'm not sure which tables/mdb file(s) are used. Any easy way to determine this? I'm backward engineering because someone got fired. Any help would be appreciated.

Working on a calendar project. I've found some helpful code, but I don't want to use someone elses whole project. So while trying to understand how all this works I'm running into some problems. I am using to start one of the simpliest codes I have found.
```````````````````````````````
Private Function filldates()
Dim curday As Variant, curbox As Integer, Tbox As Variant
curday = DateSerial(Year(Me![FirstDate]), Month(Me![FirstDate]), 1) 'first day of month
curday = DateAdd("d", 1 - Weekday(curday), curday) 'back to sunday
For curbox = 0 To 36 'need to loop thru 36 textboxes
Me("D" & curbox) = Day(curday)
Me("D" & curbox).Visible = False
Me("T" & curbox).Visible = False
If Month(curday) = Month(Me!FirstDate) Then Me("D" & curbox).Visible = True
If Month(curday) = Month(Me!FirstDate) Then Me("T" & curbox).Visible = True
curday = curday + 1 'nextday
Next curbox
End Function
```````````````````````````````````````
'Note' I have added the "T" box for additional info.....
My problem is this...... I have 36 boxes that can contain variable dates. What I want to do is on the "Click" or "DoubleClick" event of say...... box "T14" I need to determine what date is the current value of "T14" and then I can open the other form to that date. This other form would be details of whatever date is currently in "T14"
Does that make sense???? Hope so! :)
Any thoughts??
Thanks
Curtis

Anyone know of a way in Access/VB to determine what the region/location is set to on a user's computer? Need to determine whether to use commas or decimals as a monetary separator.
Thanks,

I've been stumped for the past couple of days trying to discern a method for a form to determine that it's a new month and run a procedure and only run it on month change.
My initial thought is:
Open recordset
move to the last record
compare the month in a date field within the last record to the current month
and run the procedure if the month is different.
I can't get this to work however and I'm not sure what I'm doing wrong. To be honest I typically fumble my way through VBA when it comes to opening recordsets. Here's what I got:
Code:
Dim rs As DAO.Recordset
Dim db as CurrentDB
Dim strSQL As String
Set rs = CurrentDB.OpenRecordset("FlightLog")
strSQL = SELECT [txtDate] FROM [FlightLog]
[Code] ....
txtReqNumb and txtFltNumb are the values to be reset at the beginning of each month.
Am I on the right track and just have the VBA wrong?

Greetings. :)
I am trying to position opened forms so that they are cascaded on the screen. I have discovered the movesize action (for the DoCmd) and Move property of a form (for Acc 2002/2003). However, if the application is opened up on different monitors (e.g.; 17" or 19"), the relative location of the opened form is not the same (i.e.; on the bigger monitor the opened form is too far over to the right and too high).
What I want to do is ...
When the subsequent (or second) form is opened up I would like to find the absolute location of the first form (always centered). This way I will be able to reposition the second and third forms relative to the first form.
Is this possible?
I'm having trouble referencing the first form from within the second form. The first form is still open, but they are not linked forms (not parent/child). I've tried:
forms("firstformname").left
forms("firstformname").top
but this does not work.
I've gone to online help and I've looked around in the newsgroups. But can't find any info. Anybody out there will suggestions?
Regards,
SueB :confused:

I have a table with a few Listbox options. I want one of the columns' values to be determined by the value chosen in another field. How do I do this?
Example: In column A I choose value ABC from the dropdown. I want column B to now offer values in that list of DEF, GHI, JKL. If I chose XYZ in column A instead, I'd want the column B list to show MNO, PQR, STU. Etc.

I have two related forms.One is a list of transactions and the other is used for both inquiry and adding new transactions. If the Inquiry form is just sitting in Add mode and the List form tries to open it in Edit mode, it won't open. Is there a way I can tell from the List form that the Inquiry form is in Add mode and either close it or tell the operator about the issue?

I have designed an application in Access with an SQL backend.
How do I determine the user logged into SQL from within my Access application.
Specifically what stored procedures can i use to determine
1. The user name
2. The user's group(s)
of the currently logged-in user.
I would appreciate any other techniques for solving this problem
Thanks.
Peter.

We have a database that is split. Every user has their own front end (installed via a .bat file so that the users always have a local copy of the most recent version), linked to a shared back end on a server. This seems stable and functional for us so far.
However, because our users are geographically separated, I don't actually know how many folks are using the database. I know the folks who contact me, but everyone in our company could use it if they wanted to.
For requesting funding, guiding future development, etc., I need to get some metrics:
Total number of unique users
Avg uses per day
Total number of simultaneous users (daily, weekly, and monthly maxes and mins)
What is the best way to get this info? Write user info and a timestamp to a table each time a front end is launched? Are there tools for monitoring this sort of information?

I want to run an external application (a batch file) ... and want to run it by clicking on a command button on a form. That part is all fine, using the Shell command. I can determine the start time of the application (also fine with now() function) .. but want to find out how long the external application ran and log that "run time" into my database.
The part I don't know about is the .. really the ending time. How do I determine how long the application really ran for / ended ? I imagine I can use datepart to determine the difference in the start and end times. Or would I use a timer control. (but I cannot find the timer control in Access 2010).
