Multiple Subform Causing SLOW Loading
Oct 25, 2005
Hey firstly im at the end of the project ive spent months on and thats a MIS datase software. with all the bits and pieces and expert advise ive managed to learn a whole lot of things through this forum.
This is the problem i am having though;
i have a form that has two subforms embedded and since i have to use link tables because i placed the database file over a network somehow the loading seems to take forever, "it actually makes access inactive for about 50 seconds"
i would like to prevent the subforms from loading with the main form until after the main form is up and then i just click a button that makes both of them "appear" and load.
Can u advise. Much thanks.

I have a database with a table that contains 360,000 rows. I built a form with four boxes where a user can specify values to limit the result set. And instead of having a new window open with the results, I built a subform and placed it on the main form to display the results.
Here is how it flows:
Main Form -> user enters search criteria
Search Criteria -> feed as criteria in query
Query Results -> display on subform
Subform -> shows on main form
The query is setup to take the values from the main form and either use it if it's not null, or return all values if the field is null.
The problem I am having is that on opening the main form, Access is taking the four null values from the main form search fields, feeding them to the query, which is then feeding the subform. So 10 minutes later when the main form finally opens, I have 360K records displaying in my subform.
What I would like is to be able to open the main form instantly, specify my search criteria, then run the query, then have the query results populate the subform.
What do I need to do?

By following the tips i just purchased now fast broadband but now i am facing the problem of slow loading on my local computer, is it due to any bugg with microsoft package or my system is infected by virus.

created a query (in Access 2010) that joins several linked tables (to an Oracle database). The query runs in about 20 seconds when I filter with a hard coded date (e.g., #12/31/2014#). The Oracle table column Im filtering on is defined as date/time.
When I attempt to change the hard coded value to a soft coded value (e.g., Forms![Form1]![Latest_Extract_Date]), the query runs over 5 minutes. In this case, the form field has the exact same value (12/31/2014).
Ive encountered similar issues using Access 2000, 2003, etc. This is quite frustrating. Does Access interpret #date value# is a special way? Is there a way to trick Access into the thinking a soft coded date is a hard coded date?

I'm trying to change a database that consists of a sequence of subforms held individually within different tabs on a subform. There seems to be a bit too much going on, so I've decided to leave the subforms unbound, and set them when the appropriate tab is selected, and unset them when the tab is changed. For most of the subforms, this works fine...
However! There's always an exception!!!
On one of them, when I set the sourceobject, it automatically populates the linkchildfields and linkmasterfields properties with an inexplicably crazy number of fields, most of which aren't even on the forms in question. I've tried to get around this by setting linkchildfields and linkmasterfields after changing the sourceobject. This does not work!
The first thing that happens is it returns error 2335 (relating to an imbalance between the number of fields) when I set linkchildfields. I try to get around this by trapping and resuming to the next step so it sets linkmasterfields and restores the balance, but, despite the fact that the linkchildfields and linkmasterfields are showing the correct fields, the form acts as if it has been bound with the screwy list of fields, and starts asking for fieldnames which are on neither form as parameters. When I hit cancel the subform control is empty.
I'm at a loss as to what the problem is or how I should sort it out! Any suggestions gratefully received.

I'm just getting familiar with Access and have been unable to solve the following problem and am hoping someone here could help. I have a lot (10,000s) of csv formatted files that I would like to import into a database. Each csv file corresponds to a new record in a table but the fields are arranged row-wise.
My problem is two fold. One, the fields are arranged in rows and not columns so when I try to use the "Get External Data -> Import" option to import a single file the columns and not the rows are read as fields. Two, even if they could be imported properly I have thousands of files I need to import so I would also need to automate the process, perhaps with a VB program.
Below is a sample of the csv file format: (the real files have over forty fields, and note the units column may sometimes be blank)
Field,Value,Units
name,Meta Particle,
speed,3.18,m/s^2
mass,0.001,kg
height,123,ft
width,81,meters
Is there an option in Access to import many identically formatted csv files and transpose them in the process? I would appreciate any ideas on how to load them into a table.
Thanks

I have a form with a subform (there is no child parent relationship) , when I open the mainform it causes the subform to slow down.
ie If I open the suform by itself - it opens quickly
If I then open the main - it runs quickly
If I then open the main again it runs slow or if I open the subform again - it runs slow - it continues to run slow - until I have opened the sunform by itself.
So something in the mainform is causing the subform to slow down.
Help! Thanks

I wonder if anyone could offer some advice on a problem with a form & subform?
I have a main form, based on table PublicationOrders:
POrderID (pk)
EventID(fk)
And a subform, EventDisplay, based on table Events:
EventID (pk)
EventName
The main form and subform are linked on the field EventID and my master and child links are correct, as far as I can tell.
The field EventID on the main form is a combobox, bound to field EventID in the table PublicationOrders. It allows the user to select which event an order is being sent to. In the Afterupdate property of this combobox, I have the code: Forms!PublicationOrders!EventDisplay.Requery
I would like the subform to update to show the details of the event that has just been selected from the combobox. However, for some reason, on afterupdate, the subform displays whichever event was selected when the previous record was entered. If I close and reopen the form, it will right itself and show the correct event information that corresponds with the order.
Any ideas why it's doing this? I have searched here for a solution but can't seem to find anything that relates.

I have a main form [mainform] with several subforms on it, two of which are on a tab.
On the second tab [page79] there is a subform [subformlist] which has like 25 checkboxes on it, any combonation of which can be picked by the user.
I need there to be at least one pick required of this subform, else the record won't show in a general query I have, since the table the subform is based on is linked to the record.
Is there anyway to make making a choice of one of at least one of these checkboxes checked a manditory thing before the user can close or move on to the next record?
I've tried making an "Other" box that on the Table has a default value of "True" which I thought would cause it to show in the query record...to no avail.
The only true way to make this work is to have it mandatory that the user pick from AT LEAST one, usually more before the record is complete.
Any help? Other than writing a MASSIVE If...Then statement...?
Or is there a way to make it so the choice isn't required for the record to show up in the query?
I'd post...but my db is too massive, even zipped.
:(

Yesterday I posted a question and rec'd good advice but as usual I don't think I explained myself very well.
As the attached picture of my Form shows, I have a checkbox for each Age Group under each Team. I originally had a query that would come up for each Team's particular Age Group and then the required data copuld be input. This leads to too many querys clogging things up. I tried to copy the SQL code of one of the query's to the On_Click event of the checkbox but as I have been informed SQL is different to VB.
All I would like to know is how to convert the SQL to VB coding so that I can continue to do the coding for each Checkbox.
The SQL code for the first checkbox is:
SELECT tblPlayerRegister.Surname, tblPlayerRegister.[First Name], tblPlayerRegister.Age, tblPlayerRegister.[D'n], tblPlayerRegister.G1, tblPlayerRegister.SP, tblPlayerRegister.Age2, tblPlayerRegister.G1A
FROM tblPlayerRegister
WHERE (((tblPlayerRegister.Age)<11) AND ((tblPlayerRegister.Club)="Beaconsfield"))
ORDER BY tblPlayerRegister.Surname, tblPlayerRegister.[First Name];
If there is an easier way, by all means let me know.
Any assistance would be greatfully appreciated.

I have a DB in .mdb format which works perfectly and when all the code is compiled it results in no problems. However. When I convert this to a .mde file, it doesn't work at all and it suggests that there are compile errors where there weren't any before! Please can anyone suggest what the problem might be as I don't particularly want to run this as a .mdb. Thanks

Hi,
In my database if the user wants to change a record, I make them store the old record in another table. I am using the following code.
Private Sub cmdArchive_Click()
On Error GoTo ErrorHandler
Dim conn As ADODB.Connection
Dim i As Integer
Dim s As String
Dim sSQL As String
sSQL = "INSERT INTO tblNamesArchive ( txtGivenName, txtSurname )" _
& "VALUES ( '" & txtGivenName & "', '" & txtSurname & "');"
Debug.Print sSQL
Set conn = CurrentProject.Connection
conn.Execute sSQL
GoTo ThatsIt
ErrorHandler:
Select Case Err.Number
Case -2147217908 'command text not set
Case -2147217865 'cannot find table
Case 3021 'no records
Case Else
MsgBox "Problem with cmdArchive_Click()" & vbCrLf _
& "Error " & Err.Number & ": " & Err.Description
End Select
ThatsIt:
conn.Close
End Sub
I have no problems making the following code work except if there is an apostrophe " ' " in either the txtGivenName or txtSurname . For example O'Keefe it shows an error but not O"Keefe! How do I fix this?
Thanks

I have got the following query but when it actually inserts the date, the dates will be "08/01/2005". Month and day will be swapped if date is less than 12. I don't know it's happening. It's driving me crazy.
INSERT INTO P_Timesheet ( WeekNo, StaffID, StartTime, FinishTime, TotalHours, ADate, StaffActivityID, DateFilled, NotesByStaff )
VALUES (0, 'S24', #10:00:00 AM#, #11:00:00 AM#, 1, #1/08/2005#, 158, #21/08/2005#, '');
It will insert "8/01/2005" for the first date and "21/08/2005" for the second date. my date format is set to australia and i have set the same in my asp page as well. it is giving the same result even if i try direct from the query.

I have a VERY simple select statement that I am using in a pass-through query: "SELECT * FROM dbo_vReturn;", but I cannot get this to work. Each time I run the query it generates an error: "ODBC call failed - Invalid object name "dbo_vReturn" (#208)".
The dbo_vRteturn is a view in the backend. I can open this table/view from Access using an ODBC connection but when I try to run the pass-through query it falls over!
Does anyone have any idea what is causing this?:confused:

Hi all, this is my first post, I'll try and make it a good one :-)
System:
Windows 2000
Office 2000
I have a small network of PC's here which have access to our central database. I have a simple form created using the label wizard which is used to print address labels for mailing lists.
On most of the PC's here it works fine but on one or two (which have no obvious difference in thier setup) I get an "ODBC--Call Failed" error and it won't run the report????
I have puzzled over this for a while when I decided that I would remove the Trim function from the lines of the address fields on the label, these are put in automatically by the label wizard. This stopped the error message and the reports now run.
I don't know why this is happening but I am hoping someone will.
Thanks,
Matt.

I am forced to switch from a DSN connection to my database to a DSNless connection by my hosting company. I changed my connection string from this:
strConn = "dsnname"
set MyConn=Server.CreateObject("ADODB.Connection")
MyConn.Open strConn
to the following:
set MyConn=Server.CreateObject("ADODB.Connection")
MyConn.Open = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=d:pathtodatabasemydb.mdb;"
I connect fine. But when I run a certain query, I get the following error:
Microsoft JET Database Engine error '80040e14'
The SELECT statement includes a reserved word or an argument name that is misspelled or missing, or the punctuation is incorrect.
The SQL statement in question here is:
SELECT MAX(week) AS LAST FROM Schedule WHERE Result <>''
If I change my connection back to the original DSN connection, everything is fine once again.
How would a different connection produce an error, and more importantly, how do I fix it?
Thanks,
Ted

I have a large application in Access 2003 which comprises a main program file and 4 linked data files which between them contain around 50 tables. The prog file sees the data files through linked tables. Everything works well until I do a compact and repair on the data files then unpredictable problems arise. The compaction is only ever done when all users are off the system and one file at a time. Having done a compaction this week I found that one of the tables appeared corrupt when I browsed it via the program file (the table comes from one of the files which contains other tables working OK after the compaction). The data was garbled and what could be recognised was not in the right place - appears to be moved a couple of columns out of place. There were some fields which reported errors also. However when I browse the table in its native file it is perfectly OK. I can solve the problem by re-running the Linked Table Manager in the program file but that is hard work for 50 tables! This has happened previously when I compacted and I would be better understanding the problem than just fixing it! Can anyone help please?

Hello all,
I have the following data, that was queried and sorted to columns PROBLEM_ID and then by STATUSDATE (ascending):
STATUS_ID STATUSDATE PROBLEM_ID
--------- ---------- ----------
10________12/04/2005___1234
40________15/05/2005___1234
10________11/11/2004___1235
50________15/12/2004___1235
70________20/01/2005___1235
I now want another query which returns the row which is always the latest STATUSDATE. This is what I have done so far:
SELECT qryFirst.PROBLEM_ID, Last(qryFirst.STATUS_ID) AS LAST_STATUS
FROM qryFirst
GROUP BY qryFirst.PROBLEM_ID;
However, when I want to add qryFirst.STATUSDATE to the SELECT clause, I get an error „You tried to execute a query that does not include the specified expression <name> as part of an aggregate function. (Error 3122)“
I need to see what the STATUSDATE is for each of the records returned in the second query. How do I do this? Please!!!!
Kind Regards,
Jean

I have a database with a series of fields, all set to a String datatype, that I want to be able to fill and then use with MS Word as a mail merge data source. This function lets you query a MS Access db and use the results to fill in predefined spots attached to the various data values in the table. This is great for my needs however a large percentage of times that I have a dash in the value being queried it does not return any results. For example, 01-01 would return no entry found even though I can clearly see it in the database, however it would work fine if I queried for 0101 or any other value in the given field.
Basically I'm trying to figure out why dashes would cause problems. They are obviously fine for being stored in the access database and don't cause any troubles until they are queried for, also retrieving data containing dashes is fine so long as that value is not the one being queried for.
I basically can't avoid the dashes in the data for this setup and as such hopefully can figure out why this happens and how to get around it. Thanks for any help offered.

My db is an inventory of printers in use at our company. It is to tell us where they are, and what maintenance is done on them over time.
I have the following tables:
tblIP*
tblLocation*
tblMaintenance
tblMaintenanceType*
tblMake*
tblModel*
tblOffice*
tblPageCount
tblPrinter
The ones with stars are "type" tables. All possible IP's are in the tblIP, models in tblModel, office's in tblOffice etc.
Maintenance types are just like "fuser replacement", "toner replacement", "turned on computer" (IT joke)
anyway, On my main form. If I open the form and click the button I made to go to the previous record or next, I am fine.
If I choose an office, or start a record, I get a message that I have to have a record for IP chosen, that it can't leave this new record until it has an IP because of referential integrity.
If I choose an IP and nothing else, I can leave the new record. If I don't choose IP, but choose everything else, I cannot leave the record. AHHH!!!
The thing is, all my combos on the main form are (as explained above) FK's to lookup tables, and all set up the same: all with referential integrity, 1 - many, cascade updates and deletes.
This 1 table is the only one acting this way.
I am including a print screen of my form, as a visual sometimes helps.
If anyone can help me to fix this, I would really appreciate it. I have never had this problem before.
Thanks.

I know my way around Access reasonably well but am by no means an expert. I have created a system that I use in my business for hardware/software requests, and was told to do it in Access. I did ask that we do it on SQL Server with a Web Front End, but we are where we are.
Now, I have been on a SQL query training course so I know the basics, but am a bit confused on this one since Access has been added to the mix.To make matters more frightening, this is Access 2003!
My tables are as follows:
[T_Request]
AT Reference (primary key, autonumber)
Forename
Surname
UserID, etc etc
[T_Hardwarelist]
ID (primary key, autonumber)
Make
Model
Description
[T_UserHardware]
AT Reference
ID
[Request] is inner joined to [UserHardware] on the AT Reference column.
[UserHardware] is inner joined to [Hardwarelist] on the ID column.
The select query I have is basic and does just what it says on the tin; it shows who has what hardware.The query:
Code:
SELECT T_UserHardware.[AT Reference], T_UserHardware.ID, T_HardwareList.Make, T_HardwareList.Model, T_HardwareList.Type, T_HardwareList.Description
FROM (T_Requests INNER JOIN T_UserHardware ON T_Requests.[AT Reference] = T_UserHardware.[AT Reference]) INNER JOIN T_HardwareList ON T_UserHardware.ID = T_HardwareList.ID
WHERE (((T_UserHardware.[AT Reference])=[Forms]![F_Request]![AT Reference]));
However, when it comes to adding NEW hardware to the requestI have a form called F_Request.I have a sub form called SF_Hardware.The SF_ Hardware subform runs the aforementioned query, and shows what hardware is assigned to the parent request.If I add new hardware via a dropdown on the form, it adds it in to [T_UserHardware], but it also adds another value on the [T_Hardwarelist] table. E.g. if I add a "HP Compaq 8200 Elite" (which is stored in [T_Hardwarelist]) it adds it to the [T_UserHardware] table correctly, but creates a second (third, fourth, fifth) entry on the [T_Hardwarelist] table for the same kit.
I think its confusing because of using a select query and might have to run a 2nd query on save or something like that, I had a working version before that had the make, model etc in both tables and didn't have a 3-way relationship. It'd be nice to have the request table with the high level info, a hardwarelist table with our catalog of kit, and a userhardware table just containing the ID and Reference for the hardware/request rather than duplicating the information.

Is the following possible? If so - how?
I have a series of several hundred variables being assigned values.
If the value assigned to the variable results in an error, I would like to assign a default value to the variable which caused the error.
How do I reference the variable, or line (or any info I can work with), which caused the error?

Hi,
I need help urgently. I am currently receiving files in .txt format through ftp which then reside in the same network folder as my Access Db. All the tables have been designed to read the data in. I'll be receiving these files on a daily basis. My idea is to automate this process. So, I would like to delete the existing data from the tables and then load the new set at a particular time everyday. Again, data comes in a .txt format through ftp. Please let me if this could be done and how. Thank you.
