Trouble Establishing A Subform Connection (relationship)
Feb 20, 2006
I am having trouble establishing a subform connection (relationship) to a main form. I am using Access 2003.
I am creating a medical record database where I already have one form / subform relationship established that works. However, I created another form where I want to indicate the Physician(s) information within the main form and his specialties within a subform. I need to use the subform because one physician can have more than one specialty.
My fields within two tables are:
Doctor (Table)
ID
Doctor First Name (Key)
Doctor Last Name (Key)
Doctor Address
Doctor City
Doctor State
Specialty (Related Field)
Doctor Specialty (Table)
ID (Key)
Doctor First Name
Doctor Last Name
Specialty (Related Field)
The problem
I can’t establish the relationship.:confused: Also, when I look at my relation diagram – does each table have to relate to another? Can I have two separate relationships indicated?
hi guys, this is my first thread on this forum...,, i am new out here..
i am not able to establish a connection with a MS Access database. I am using DSN Connection for it..
The error that i am getting is...//
Error Type: Microsoft OLE DB Provider for ODBC Drivers (0x80004005) [Microsoft][ODBC Microsoft Access Driver] The Microsoft Jet database engine cannot open the file '(unknown)'. It is already opened exclusively by another user, or you need permission to view its data. /airtickets/scripts/dbconn.asp, line 4
I'm trying to use a banner ads .asp program called Admentor. My problem is that this uses DNS less connection and I can't get this working on both the pages showing the ads and the admin panel.
I know it's the path to the database that causes this. If I change this to suite the webpages showing ads, it work's, and if I modify it to suite the admin panel it work's. But not both at the same time.
Should'nt this path be relative to the sites root ?
when using this string, the webpages showing banners is working, but when clicking on these, the site calles a redirect .asp page that also uses this database connection. Then it fails, since this page is located in another folder in the site and therefore also gets another path to the database.
How can I get this to be a relative path working on all pages not been worried about folders, subfolders and correct paths to the base ???
Glad I found this forum. First question as user :)
I have a database I am creating with a number of subforms. A few of the subforms I want to be able to quere data from a ODBC connection. When I use the combobox to select a system, the subforms with ODBC connections are not updated. I will not be updating any of the data on the ODBC.
Should I just create a macro that does a delete quere and then make-table quere, or is there a better way?
I'm having a problem with a form/subform. The table I'm using includes the fields: date, personnelID, status, comments. The main form has a single field, date. The subform has the fields date, personnelID, status, comments. I have the form/subform linked using the Date field, because there are multiple instances of the same date in the table, I have to keep clicking the navigation buttons on the main form to go through all the duplicate dates to get to the next one. Is there a way I can filter the Date field on the Main form to only show one copy of each date? I had thought about creating a new table with only a date field and no duplicates, then just append all dates from the main table to this one and use it to go through the dates, however I'd rather not have to make an extra table just for this. This is basically for personnel accountability, I want to be able to select a date on the main form and display the "daily status"(present, on leave) for each person in the subform.
Even better would be if I could create a next and previous button to switch the date on the main form(I know how to do this.) but how would I get the subform to update the records to the date on the main form and keep it from going to dates that don't exist?
I have a subform that has a combobox which is bound to PersonID in the many side table. It looks up people who were previous attendees, with provision to add other people who were never attendees but exists somewhere in database or to add new attendees.
The problem with the combobox is that despite being bound to many siide table's foreign key, it somehow thinks it should assign an autonumber which causes an error 3341 whenever adding a existing record.
I've checked both the subform's recordsource, combobox's recordsource and rowsource to ensure they are bound to foreign key, not the primary key but it still acts like an autonumber. I've already checked the many side table design to ensure that foreign key is simply a number type, not autonumber...
I have a main form (stud_details) also I have a subform called (pay_det_sub).The subform is displayed on the main form. I want to create a relationship between the stud_details and pay_det_sub, with the aid of a field on the stud_details called numhus (which is the primary key).
So that when a student with a specific numhus value is displayed it brings about the payers details on the subform.
What's the best way of doing it??? Is it necessary to have numhus value stored also in the subform table to create a relationship....
Hi. can anyone help me. I've spent the last two hours getting no where.
I have a tbl_Enquiry,tbl_EnquiryType and tbl_Questions On the main form (frm_Enquiry), depending on which enquiry type is chosen, will depend on which questions are displayed. this is a many to many relationship so I have a junction table, called tbl_TypeQuestionJunction.
The questions are displayed in a sub from when the enquiry type is selected, and this all works fine.
However, I then need to add a field where the user can write thier answers to the questions. for this I have a table tbl_QAJunction with the fields EnquiryID QuestionID and Answer
How can I get my subform to display the correct questions when the enquiry type is selected, with an answer box next to it and then pick up the EnquiryID, QuestionID and the answer and add them to the tbl_QAJunction. I just can't get a query to work.
I hope this makes sense
This has really bugged me and is stopping me completing my database. Am i going abotu this all wrong? If anyone can help, I'd be grateful I've attached a cut down version of the DB so you can see what i'm on about
I am assuming Access cannot handle Many to Many relationships very well.
I have an Account form ("MainForm") with an embedded SubForm that displays only the Account Address with suite number, street number, street name, street type. Account to Address is a Many to Many relationship. My Account form's source is tblAccount, and the SubForm is built off of a query of 3 tables -- Querying Account, LinkTable, and Address table. The link between the SubForm and the "MainForm" is done via AccountID.
My problem is, when I query for an Address (say entering a street number of 25), I want to get back all the addresses with street number of 25 AND the corresponding Accounts that have street number 25 only
What it does is return the addresses with Street Number 25 and ALL the accounts regardless of what their addresses are!
Is there a way to do this?? Can I design a form without using a SubForm in this case, ie, display the account and its many addresses? Or does Access Forms not support Many to Many Relationships? I'm thinking the link table is causing the problems here.
Please advise -- this "simple" project is becoming quite the headache! :eek:
"edit" -- I also notice this problem with a 1 to Many relationship (the "many" portion being the subform)
Hey guy im kinda new to this program so excuse me if my question is simplistic:I built a form for making Purchase orders. In the main form...a user enters a bunch of text/num info (name, address, ect)into the table. After that i have it tab to a subform..where a user can add items by line (as many as they like). All good till here: Once i go to click out of the subform...i get message "You cannot add or change a record b/c a related record is required in table 'UCT_Req'"My relationship has a 'one-to-many' link (the req number to the many line items). I have auto-numbers counting up in each table.My main problem seems to be attaching the entered line items to a specific record in the main Purchase order form...and then opening a fresh form afterwards. Any hints?Thanks folksSTeve
I have a Workorder Form that holds all the fields that apply to the entire project (payment, customer, etc).
Then I have a subform for Stock. This allows there to be several different stock items (and production information relevant to that stock) assigned to a Workorder.
I have successfully linked the two so that when a Workorder is opened, it shows any related Stock in the subform that has already been created.
The problem is new stock entries. I need it to only allow Stock additions to the current open related Workorder.
I currently have it where you can type in the WorkorderID (autonumber) on the Stock subform new entry and it will work. But I do not trust employees to type in the correct number every time they need to add stock to a Workorder. I can't release it this way.
I mean, the whole point is for the database to promote as little error as possible, right?
I have a "Main" form called frmProjects that sports multiple tabs. One of those tabs is labelled "Milestones", into which I inserted a datasheet subform called frmSubMilestones. The table that feeds the subform is tblMilestones. I established the parent / child relationship between frmProject and frmSubMilestones, and everything is working just fine...
To summarize: frmProject as main form -> Milestones Tab on main form -> frmSubMilestones as datasheet subform on the Milestones Tab (there are other tabs that are not subforms).
I have been asked, for each milestone in the frmSubMilestones subform's datasheet, to capture the number of days spent by employees on a monthly basis. The Milestones table and the PersonDays table have a primary key and a foreign key that are similar.
To summarize: frmSubMilestones as subform -> txtAggregatePersonDays as calculated Textbox fetching data from tblPersonDays -> OnClick event -> FormLoad of frmPersonDays as datasheet PopUp form.
DoCmd.FormLoad is supplied with the usual parameters to make the PopUp form appear, filtered on the currently highlighted milestone. Everything works fine so far... well almost.
Problem 1: When I introduce new rows in the frmPersonsDays datasheet, everything seems fine at the surface, BUT the primary key of the calling form (i.e. frmSubMilestones) does not appear in the tblPersonDays table; this is normal because there is no form-based parent / child relationship between the two forms. As one might expect, I am trying, from frmPersonDays, to get the primary key value from the "parent" frmSubMilestones using the Forms collection. No dice. I surfed and surfed, tried the bang and the dot operators, drank scotch, but nothing worked. I had to add foreing keys manually in tblPersonDays to further my tests. I can't figure out how to reach any control on the calling form, which is a subform.
Problem 2: The calculated txtAggregatePersonDays on the frmSubMilestones works wonders for existing data in tblPersonDays. However, when I introduce new rows in the PopUp form, I also realized that the calculated Textbox in frmSubMilestones is not updated when I close the frmPersonDays PopUp. I have to close the PopUp form and move the cursor in the Main form (frmProjects) to refresh its associated milestones.
I have a form, frmProjects, with a continuous subform, sfrPeopleOnThisProject. They have a master-child relationship. The form shows one Project record at a time, while the subform shows all the People records for that project. This works as expected - the correct records show up in the subform as you move through the form records.
To make it easier to glance through the list of subform records (as they can sometimes be quite long), I've added a navigation combobox to the header of the subform. If I understand correctly, as the combobox is within the subform, it should obey the master-child relationship: it should only show the subform records associated with the main form's current record. It does not. Instead, the combo box collects *all* of the records from the table that the subform is based on. So, choose the record for Project 1 in the main form. Up pops the 2 people on Project 1, but the combo box lists both the 2 people on Project 1 and the 3 people on Project 2.
The row source for the subform combo box is:
SELECT tblPersonOnProject.PersonOnProjectID, tblPerson.Fullname FROM tblPersonOnProject INNER JOIN tblPerson ON tblPersonOnProject.PersonFK=tblPerson.PersonID ORDER BY Fullname;
I can make the combo box perform as required by adding "WHERE Project=Forms!frmProject!ProjectID" to the row source and placing a hidden textbox on the main form for ProjectID (the autogenerated primary key) to sit. Have I misunderstood the point of the master-child relationship in the subform? This hidden textbox thing can't be correct.
Right Ok i hope i can get some help cause im absolutely stumped.. i cant get my login page to work since moving it from my PWS(iis on xp) DSN connection to a 24/7 server on the net with DSNless connection here is the code for the include file "conntopwd.asp" http://www.pritchardwebdesign.pwp.blueyonder.co.uk/conntopwd.txt the username and path has been changed slightly for security purposes, and the code for the login page which attempts to access the database is here http://www.pritchardwebdesign.pwp.blueyonder.co.uk/login.txt the connection has been tested by one of the tech support guys at brinkster and he told me it was ok, the problem was the way that the data is called from the data base is wrong .. The tech support guy said that it was this line that was causing the problem.. MM_rsUser.ActiveConnection = MM_conntopwd_STRING Any help would be much appreciated as im stuck for now..
I have a data base that I use ADO primarly to connect to the backend access database. Each time I query a table I create a new connection and then kill the connection after I'm done with it. Should I be creating a global connection and leave open the entire time the program is open, or should I be killing the connection each time?
I simply want to create a connection to an Access db, and run an execute an SQL statement. I have only used RecordSets in the past, so this ADO.NET is completely new to me.
Can someone give me a sample code to execute an SQL statement, and take the result and assign it to a string variable?
I can bind my results to a DataGrid, but if I need it in a string, what good does that do me???
Also, I am only familiar with VB, but if someone has to post it in C#, I'm sure I can figure it out! I appreciate any help.
hi everyone; I'm trying to make an ADO connection to my local database named "dbTest.mdb". Here is the code I'm writing in my editor:
Code: <body> <% Set CN =server.CreateObject("ADODB.Connection") CN.Open "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:InetpubwwwrootNew FolderdatadbTest.mdb;Persist Security Info=False" Set RS =server.CreateObject("ADODB.Recordset") Set RS.ActiveConnection = CN RS.Source = "select * from tblTest" RS.CursorLocation = adUseServer RS.CursorType = adOpenKeyset RS.LockType = adLockOptimistic RS.Open response.Write(RS.fields(0)) RS.close Set RS=Nothing %> </body>
and this error comes up in my browser:
Code: Error Type: ADODB.Recordset (0x800A0BB9) Arguments are of the wrong type, are out of acceptable range, or are in conflict with one another. whats the problem with my code???!!
Rookie Alert ! I am trying to incorporate simple Access database to web page. In page one, I use Database Results Wizard to display records in database. I pass parameter (last name) via hyperlink to second web page to view complete record. I always get no records found. When I asked tech support, they sent me this:
We do not have registered DSN's on the host server. You will need to use a DSN-less connection string using an absolute path to the file. The path to your account is c:accountsusername and from there you would add the path to the db within your home directory, I.E. -
I have seen other references to this and I have tried what they said with no luck. Where in the page code would I put this? I am using Frontpage 2003. Any suggestions would be helpful or a working example would be nice.
I will create an Access application as a Front end application. The matter is that the users will need to update some data from Internet where there is a MySql server. I thought in creating a local DSN to connect to that MySql server. Is it right ? I already created it but... I dont know the code to connect it from Access. Could you please help me with the code to write in Access ? Im a new with it. sorry. Or you can send me an example of it in an Access database to: osvaldo@ord.com.ar
I am creating an Access database that will be used by multiple users. This database will be on the network and will be the front end of an oracle database connected to it via ODBC. Do I have to set up the ODBC to oracle only on the machine that hold the database on the network or do I have to set up an ODBC on each user's machine?
i'm create a aplication in ms access 2000 developer edition. this app comunicate with sql 2000.
we have problem with slow connection provided by access. in headquater wher people use access app it working quickly. sql 2000 is localted at headquarter too. but if i run app in warehouse it working very slowly.
VPN connection doesn't slow. but access can't use all vpn connection capacity but only 1/5 from this capacity?
how can i do something that acces can use all capacity that i have?
example: link is 512 kbps but access use only 100kbps and work very slowly.
I have a small access database that my users keep open all day long. Access 2000.
I have one primary version of the DB on the network. No one uses it. I have another file on the network that has linked tables to the primary db. I copy a version of this DB to each workstation.
So each user has a full blown DB on their desktop with linked tables back to the main DB. Is this a good set up or are there any issues doing this? What is the best set up for multiple users across the network? Thanks.
one another database have started showing a new error "the database has been placed in state by user 'Admin' on machine 'XXXXXX' that prevents it from being opened."
I read some of the articles on google and find out tht database splitting is solution for this. Now my question is if after splitting i keep the front end and back end at the same location does it gonna effct some how? i mean even after spliting if users use the same copy of database as fromt end. Does it make some sense.
