Tab Controls And Linked Subforms With One To Many Relationships
May 8, 2006
Hi there
I've got 3 tables related to one another with one to many relationships. They are:
21_Category
22_SubCategory
23_Indicator
where the 23_Indicator table has 22_SubCategory as its parent and 21_Category as its grandparent.
The forms wizard in Access has nicely developed a form with 2 subforms contained on it which does the trick for maintaining all 3 of these tables. The form itself displays 21_Category, subform1 displays 22_SubCategory and subform2 displays 23_Indicator. When I change the active record for either Category or Subcategory the subforms change their display as expected. All good.
My concern is that the form looks a mess and not very welcoming, too much info on one form, so I'd like to replace the 2 subforms (or even form plus 2 subforms) with one Tab Control. So far I can get the linking working correctly to the first page within the Tab Control but cannot link the second page child records to the active record in the first.
I'm using the Link Child Fields and Link Master Fields to do this. Even straight copying of the entries from my subforms which already work cannot get the Tab Control to behave in the same way.
Without wasting any more time on this, does anyone know whether it is easily possible or I'm missing something obvious? I suspect I've got something slightly wrong with either the Source, Link Child Fields, or Link Master Fields syntax, or referring to the wrong objects. Alternatively, Tab Controls just aren't designed to show one to many type records??
I'm not a VB Developer so if this isn't possible without writing a whole heap of code then I'll just have to cut my losses and use the crowded form I already have, though I'm happy to insert a few lines to get the Tab Control to work.
Thanks for your help in this. Apologies if this has already been posted loads before. I'm doing this as voluntary work for a charity and I'm a fairly new user of Access and VB (though I'm familiar with databases and SQL).
So I swear what I want to do isn't that difficult....ok so I can't get it to work, but I'm sure one of you gurus out there can. I hope =) At the very least tell me if it’s possible to do.
I have a form (Edit Expert) on this form is a combo box with a list of all the experts names. Below is a tab control with 2 tabs. Each tab has a subform on it with different info pertaining to experts. (contact info and education) what I want to happen is that when someone selects an expert, I want that experts info to be populated into the subforms. I have tried a macros (findExpert) that is attached to the after update property of the combo box. When there isn’t a tab control on the form and there is only one form, it works great, with tab control it says my filter isn’t based on a table or query and to use selectObject. However I have no idea what object to select. I have read the word doc that is floating around the forum about the syntax for main/subforms, but have gone in circles. However I am reasonably sure that that is were my problem is. I need to tell access to apply the filter to the subform on the tab control.
I tried to zip my db, but no matter what i do it's too big, so i hope this is enough info for you to go on. Please let me know if you need more information. Thanks a billion for your time and effort!! - me
In the attached picture has a representation of my setup.
My main form has a listbox search form (taken from this site). The search results populate data in subform1.
In the detail section of main form has subform1 with 3 cascading combo boxes. I have queries set up that run the cascading combo boxes.
In the detail of subform1, I have subform2 with a combo box.
Today I decided to merge my search form and the other forms so I wouldn't have two pages. Everything used to work with no errors - but I can't figure out how to reference everything properly now.
I've tried every combination from here to reference things properly. Somehow, I'm missing something.
If someone can help solve this for me, I would be forever grateful. I have attached the database to which I am referring for clarity.
I am creating a database designed to input data for morbidity and mortality at my hospital. I have set up four main tables: tbldemographics (basic patient information), tbladmissions (information about each different admission a patient may have), tblmorbidity (information about each untoward event suffered by a patient, which I would like to have linked to the specific admission, not just the specific patient), and tblmortality (information about a patient's death, which I would also like to have linked to the specific entry in the admissions table rather than linked to the more general information in the demographics table).
I have created relationships which I thought would work--but with referentail integrity invoked (which it seems like it should be), the very first key stroke on the form that I created to input the data (frmmain) results in an error message that the record can not be added or chaged because related record is required in tbldemographics--and yet this is the table to which I am inputting the data! Turning off referential integrity stops the error, but I don't want to just blindly do that--seems risky.
Problem number two: when I disable referential integrity and enter data into the demographics section of the form, any entry at all results in an automatic entry into the admissions table--even if I haven't entered that part of the subform yet. So if I then exit the form and return later, ANOTHER entry into the admissions table is made--again, even if I have not ventured into that subform yet. So that table winds up with bunches of entries with little to no data, which are NOT cleared up with a compact and compare maneuver.
I'm at a loss on both of these issues. I apologize for the long post, but appreciate any ideas you all might have.
With a many to many relationship using a junction table, do I have to manually plug in the ID numbers from the related tables in the junction table for it to recognize the related data? It sounds silly and obvious I guess that you would have to, but when I go to create a form based on a many to many relationship, I would like the ability to enter data without having to enter the related ID numbers in multiple places on the form or subforms to make it work. I guess I envisioned access using auto numbers to automatically update the junction when I wanted to add data related between the "main" table and the distant table joined with a junction. Can this be fixed using a Parent/Child relationship set-up in some fashion?
I have created a form with two subforms. The context of this is a litigation database. The main form is for testimony. Among other things, it includes a field for a question and an answer. Any given piece of testimony may relate to one or more documents, and any document may be referenced in one or more pieces of testimony. So have two subforms, one for documents produced by the Plaintiff, and one for documents produced by the Defendant. It worked out easier that way because I originally created indices of those documents in separate Excel tables which I then imported to Access.
So the relationship for both document tables relative to the testimony table is many to many, which is established using two junction tables.
I also have a combo box in each subform where I can autofill fields based on selection of the document number.
My problem is that while the combo-box works great, once I select a document in the subform, that selection is carried over into the next entry of the master form, but also the selection is not retained in any of the master forms. So I can browse the document listing from any entry in the master form, but I can't get the document selection in the subform to stick and create a lasting relationship to a given record in the master form.
Is my problem that it is just impossible to have a subform based on a many to many relationship, or is it in the parent child relationship of the form and subform, or is it in the properties of the subform?
I'm upsizing an Access 2000 application to Access 2003 + SQL Server 2005, and I've found something I cannot get through.
The original application was a file 'app.mdb' with all tables, and another file 'app_exec.mdb' with all forms (tables in 'app_exec.mdb' were linked to 'app.mdb').
There was a table called T_Order (I will call it A) and another table called T_Order_Line (I will call it B). * Table A fields: Id (Primary Key) and Customer_Id * Table B fields: Id, Order_Id (Both are Primary Key) and Article_Id.
There was one form (called frm_A) that includes a subform (called frm_B). The form frm_A allows navigation, adding, deleting and updating 'A' table. The subform frm_B shows data related to current 'A' record.
The subform frm_B allows you to add/delete/update records to the table 'B'.
Now I only have one file 'app.mdb' with forms and tables are linked to a SQL Server 2005 database (I use the Access export wizard).
frm_A and frm_B are related using "Link master field" and "Link child field".
The problem is that I cannot add new data to the frm_B. Navigation in the form works. In the subform frm_B I see data related to the current record. I can delete/edit data from frm_B. But I cannot insert new data on it.
When I click on "Add New Order" button, I execute the code "DoCmd.GoToRecord , , acNewRec". In the old application, frm_B was cleared and ready for appending new data. But with linked tables to SQL Server, I cannot add new data!
I have checked that if table 'B' is stored locally in Access, everything works fine. But if I use table 'B' linked in the SQL Server, I cannot add data.
So, I am sure that the problem is only with table 'B' and the subform, but I cannot understand what happens.
I have a database with a table on a shared network drive. The table contains a list of buildings, building details and a unique building code. I want to be able to use that database as a master copy so any new buildings that need to be added can be. I have another database with accounts and another database with some other information. I can create a relationship between the accounts and the linked table of buildings (by the unique building code) but if I am to go into the building table, there is no "expansion option" to see all the accounts for that building. Is there a way to create a proper relationship or at least make a copy of the buildings table so that each time the database starts up it can get the latest version?
I have some linked tables I'm using as subforms. I'd like to make the data a little more readable rather than numbers that my linked table spits out (can't do anything about it).
In my main form I can use the control source and enter something like this: =IIf([FieldName]="1","Male",IIf([FieldName]="2","Female"))
I can put as many statements as I want, just add a bracket at the ned for each one. Works great.
This however does not work in the subform. I get a circular logic error. If I then add a table reference like: =IIf([TableName]![FieldName]="1","Male",IIf([FieldName]="2","Female"))
The error goes away, but it still displays as #Name?
Hey all, i would appreciate some help with Access here.
I am an attorney, and i am trying to set up an access database for all of my cases.
I have one table in which i keep the names, contact information, etc of all the witnesses who i have used or will be using (especially expert or law enforcement witnesses who i will be using in multiple cases).
I also have a main table in which i have a record for each case. Because I have multiple witnesses for most of my cases, I have had to create multiple relationships between my main cases table and my witnesses table.
My question is this: How do I specify when setting up a report (or a form/query/etc) that when i ask for the witness's address i am looking for the address i made with a particular witness, specify that relationship between the two tables, as opposed to the other relationships between the same two tables.
I hope that makes sense, and i would very much appreciate if someone could give me instructions.
I have one database called asset management. It consists of one main table called cyber assets. Most fields in this table are linked to a manually created lookup table inorder to restrict user input. There are also two additional, none lookup, tables used to list a) the IP addresses (there can be more than one) and b) another similar 1 to many type table. Basically this DB is used to manage basic cyber asset data, excluding most items related to configuration management.
So, this above DB serves the purposes of asset management. Now I essentially need a similar DB for Patch Management. What I've done for this is to assess each patch initially (i.e. just by looking at the patch title and determining if we even have any of those device. i.e. this assessment is not based on OS, model number... just a general 'may' or 'may not' be applicable). Here's what this SEPARATE DB looked like:
Since each patch is essentially assessed against itself, or maybe a better way to describe it is against the users memory of what we do and don't have, only a single table and form was needed.
So now we've been thru this process and the DB is filled, all initial assessments are complete. The next step is to take all the ones that are applicable to our company (based on the initial assessment when you answer, yes is applicable) and do assessments based on each device we have.So what I want to do is to link the two DBs on a new table called Patches_by_device, inside the original patching DB... so the relationships would look like this:
But as you can see, the linked table CYBER_ASSETS has some sort of undefined relationship type, which is causing my issues.So the next thing I did was to autocreate a form based on the Patches_by_device table, and here's the result.I need to change the patch_key to the Patch_ID+Patch description+URL, etc, and to change the device key to the the UNID+IP+functional description, etc...so I changed the form record source like this:
Now I should be able to change the control source of the Patch_key and Device_key to more useful information. so I changed: Patch_key control source to Patch_ID and Device_key control source to UNID (which is in the cyber assets table)
As you can see, it worked for the patch_ID but not the UNID which is part of the linked table.Must it be within one DB, because we have a ton of other modules to implement (e.g. config management, vulnerability assessments, audit stuff, and more...) and I'd like all these to be in individual DBs, all liked back to the main cyber_assets/Asset management DB.I've considered just modifying that patch table so that each device has its own column heading in the table, but this will cause issues when new devices are added.
I have an unbound form on that form I want to put three sub forms one on a products table the other on a course start dates table and the link table that joins the other two together. all three are related to each other with Pk/FK links.
When I try to link them it says you cannot link items on an unbound form.
I have a database with a number of linked tables that are linked to tables in different databases (not a back-end).for example, I have table1 that is linked to table1 in K:databasedb1.mdb.table2 linked to table2 in S:datadata.mdb.and so on...
However, recently we have moved all our databases to a new location.
K:databasedb1.mdb is now residing in O:masterdatabase and S:datadata.mdb is now residing in O:masterdata and so on...
I'm now in charge of relinking all those tables to point to the new location.I would do this in linked table manager one by one but we have 100s of tables linked to multiple different databases in different location.is there a way to create a VBA code that will automatically do this re-linking process?
so, 1. find unlinkable tables 2. search its new location under O:master 3. re-link it to the new location
Database names and tables names have not been changed. Just the location of databases.
I am trying to build a Form that will show an estimate (then eventually will be moved to a project if customer and employee aggree to price and project) in a Form F_Estimates is a M_Customers(Customer_ID) (Based on a Table) and thier info in a Subform. Also is the "projected costs" from parts out of the Parts(Part_ID) (Based on another Table) in a second Subform as a list that I need to calculate $$$ in (Dang that still sounds evil and definately NOT understandable even after edit... so)
Here's some basic info
Tables
EstimatesandParts - Table EstimatesandParts_ID : Autonumber Estimate_ID : Number Part_ID : Number
Parts - Table Part_ID : Autonumber PartNumber : Text (not a number due to some part#s have letters in them) PartName : Text Unit Price : Currency Description : Text
Estimates - Table Estimate_ID : Autonumber InvoiceNumber : Text (again can have letters in it) EstimateDate : Date/Time EstimateTime : Date/Time Employee_ID : Number Customer_ID : Number ProblemDescription : Memo
Customers - Table Customer_ID : Autonumber FirstName : Text LastName : Text CompanyName : Text Address : Text City : Text Province_State : Text Postal_ZIPCode : Text (CDN Postal codes are letter num letter...)
you can see the link table in the EstimatesandParts Table
Now I want to use that link to populate a subform in the F_Estimates form
Forms
SF_Customers - SubForm
(all boxes atm are text boxes on this form till I figure out the Parts section then will use same base for this so I can pick any customer in the database to be the customer for this estimate. Also will have ctrl button for making new customer with customer form and a refresh on Focus Gain bit of code)
FirstName LastName CompanyName Address City Province_State Postal_ZIPCode
SF_Parts - SubForm Default View -Continuous Forms
(want it to be a list of parts that I can grab prices and descriptions from then in a bit of code to calculate a cost of parts)
Part_ID : Combo Box Control Source - Part_ID Row Source Type - Table/Query Row Source - SELECT Parts.Part_ID, Parts.PartNumber, Parts.PartName, Parts.UnitPrice, Parts.Description FROM Parts ORDER BY Parts.Description;
(Pulls info from the table Parts for input into a list of parts to be used on that project)
PartName : Text Box UnitPrice : Text Box
(here's where I run into problems due to the fact that the form is not based on the parts table but rather the link table EstimatesandParts so I can't propogate the info to the 2 other text boxes, ps I dont care if they cant be text boxes and have to be linked or some other type I'm not "set" just need to find out how to make it work )
(have tried a couple things to complete this task)
(works AWSOME ... for ONE ROW then propogates the second selection to the first and second and third selection to first second and third and so on ...)
(tried to make control source for the txtPartName to)
=Forms!Parts!Partname
(Doesnt exist .. akkk, cant use ActiveForm either as it doesn't focus on the SubForm but the MainForm ... cry)
(Combo Boxes Select Customer and Employee from list of present ones of each)
SF_Customers SF_Parts
(Both SubForms on the main form)
Now this is an Exerp from my entire Database I like to work on one small problem at a time and I have made this its own little database till I figure out the problem then I will bring the info I learn back into the rest of the database and go from there ...
Hope you can help I have a feeling I will need to make a recordset and go from there but I'm just not able to wrap my head around that for some reason
Thanks in advance for ANY and ALL help that I get from here
I have a form in my Access database that after trying to add another field to it today, I get the error "Microsoft Access can't create any more controls on this form or report."
I'm guessing I reached some type of limit that I was not aware of. How can I get around this?
I read somewhere that you can have more than one row of tab comtrols on a form. I have searched the forum for any threads or posts on the issue but can't find anything. Does anyone know how to do it?
is it actually possible to place a tab control within another tab control? every time i try to put one on it ends up beneath? would be good to have because even with one tab control my forms still look very busy!!
When I step through the table if the code finds "No" in Field1 then id makes the subform referred to in Field2 invisible and if it finds a "Yes" it makes it visible.
Does anyone know how to have a datasheet view in a subform fill the top of the main form? I want to be able to see the records in a datasheet view and when the record in the datasheet view is selected it prefills the top of a form ?
This is a question from yesterday that a member had helped me out with.
I have additional questions while I am waiting for response from him. If anyone of you can help, I would really appreciate it.
1. How can I make a form that gathers information from multiple tables? 2. Lets say it is possible, how does this info get saved to these multiple tables when the user clicks on the next record button on the record navigator.
Pretty straightforward. Now, I have a form to view Companies, inside of which is a subform listing Projects associated with the Company using the above query.
The issue that is stumping is that I would love to be able to add a new project from the subform. I thought it would be pretty easy, but I'm totally dry. I guess I need to grab the CompanyId from the parent form, and assign it to the new record before I can add any more data to the new record. But I have no idea how to do this, or even if it is the right thing to do.
Any help would be _greatly_ appreciated. I've been slamming my head against a wall with this for two weeks.
Hi, I have 3 tables : Products, Description and ProductDescription. Products can have more then 1 description, Descriptions can be used by more then 1 product, that is why the third tabel ProductDescription exists (normalizing..:) ). The Productdescription table has 3 fields: id, productid, descriptionid.
I want a form in which you choose a product, then you see all the descriptions along with it. In this same form I want to be able to add a description, e.g. by pushing a button NEW. After that user enters description form etc. After returning to the mainform, a new record must be automatically added to the ProductDescription table and ofcourse a new record has been added to the Description table. I thought I would use subforms to realize this but it isn't working..:( . I have tried so many things that I dont know anymore what to do, i am totally confused. I know how to program in VB and ACCESS, but for now i don't see it anymore. Can someone please help me with this?
I just need to know how to start, what to use as subform and what as masterform, which links between fields, etc
