Forms :: Trying To Create A Subform That Updates A Table
Jan 6, 2015
Here is the set up. I have a primary school database.
There is a main form that shows the students name and class.
The main form contains tabs for each subject (maths, english etc.). Each tab has a subform that is supposed to allow me to enter a comment about the student's progress.
My tables are set up properly (as far as I can tell).
The tables (simplified)
tbl_Students (has StudentID, StudentName)
tbl_SubjectList (has SubjectID, SubjectName)
tbl_Comments (has CommentID, SubjectID (foreign key), StudentID (foreign key), Comment)
The forms
The Master and Child (main form and subform) are linked using StudentID.
I use a query for fields in the Master form. Each subform has its own query that shows results for a particular subject.
The problem
My subform allows me to edit an existing comment fine (if I enter dummy data directly in a table).
BUT, if there isn't an existing comment, and I attempt to enter one, I get an error - "YOU CANNOT CHANGE A RECORD BECAUSE A RELATED RECORD IS REQUIRED IN TABLE tbl_Subjects."
What I have tried
I understand this error means I am violating referential integrity rules. But I can't see why. The tbl_Subjects is populated with 10 subjects and I am only trying to put a comment against an existing SubjectID.
I've checked that my Form Master / Subform Child is ok. I experimented with having StudentID _and_ Subject_ID to link the master and subform to see if that worked. It only made things worse because my subforms wouldn't display correctly.

I need to create some new records based on main form data and a selection of records from a sub form. The main form and sub form have different sources. I wanted to show the source fields in the sub form along with a check box to allow the users to select individual records. The record source for the sub form contains >1000 records, so the user will first enter data in the main form, use filters to find the records he wants to 'assign' to the main form data, click those he selects, then click a command button in the main form to create the record(s) based on the main form data and the selected records from the sub form. The new records will be appended to a new table.

I have a table in my DB named TblStock and another named TblStock2..I also have a form in the DB named "frmStock" with the control source being "TblStock" . This form has a sub form "FrmStock2Subform" with control source being "tblStock2". The two forms are lined by "PurchaseID". This form is made to be used in entering products that have been bought for replenishment of stock.The problem I have is that when I enter data in the main form, by the time i click on the subform to start entering data, the table "TblStock" gets already updated.
Now lets assume somebody was about to enter data in the subform and later on changes his mind when the "TblStock" had already been updated, this will cause a waste of useful space because there is no corresponding record in the table "TblStock2". Secondly, if many users are entering data into the DB using that same form, I guest there will be some problems too.What i want is that the form should update both tables when the users validates the records.

I want to create a database that keeps track of contributions of members of an association. Every member can voluntarily give a standing order to contribute a fixed amount every month. A member can as well decide to review his/her contribute.
how I can come up with a database that can automatically add the contribution of a member monthly without manual input since the stated contribution is known. So that I can run a report for individual member and the report can capture the every monthly contribution that has been added automatically and shows when ever a member changes his/her contribution amount.

I've got a hopefully an easy question - how to create a form filter? I've got a form with a subform. Form is showing all records from a table, but some records on the subform are blank. I want to create a filter which will eliminate any record from the form where there is nothing to show in the subform.

I have a form (frmAddManifest) with a subform (subfrmManifestTransporters).
When creating a new record, I can enter data into frmAddManifest, but the subform doesn't update to link with the record - I presume it's because the record from the main form hasn't been completed yet.
Is there a way to requery the form and/or subform so it stays on the record I was working on, and link the subform properly?

How do I create a table relationship where a secondary reltated table stores past dates, status code and customer ID. For example: I want to keep track of the past dates that an order was revised and why it was revised. So, if I have a customer who was due for installation on 10/21/04 and status is PEND for pending. THen on 10/18/94 I change the date of PEND to 10/25/04. I want to keep track of the times it changed and the reason why. HOw can I make the program automatically create a record in the revision table storing the past code, reason and date using customer ID as key and teh revision table would allow multiple records for each customer ID. DId I make sense?

In the attached DB I have a form that has a combo box which enables you to select an employee and all the employee info is then pulled based on the selection. I want to make changes to the info in the form and have the changes update the correct employee on the table. Currently the from will not let me make changes to the info and the table seems to add new lines rather than updating the corresponding line.

I use a form for changing data. So when the user selects a record from a listbox I fill all fields of the form with the content relating to the selected line in the box. Nearly everything runs as wished.
All updates take place immediately but the Boolean field does not update or better it updates only after I move the cursor over it. Then it is correct. To make it clear, I do not need to press a button or click, I only move the cursor over the boolean checkbox.
I access VBA after clicking the line in the listbox and use the dlookup command to get the right values. Do I need something like a requery for a boolean field ?

I'm trying to update a combobox(called TypeCombo) list values after I select a value in another Combobox(called manCombo). The values for both Combobox comes from the table called EquipmentTable. Which has 3 fields Manufacturer, Type and Model.
Code:
Private Sub ManCombo_AfterUpdate()
Me.TypeCombo.Value = DLookup("[Type]", "EquipmentTable", "Manufacturer = " & Me.ManCombo.Value)
End Sub
I know that the value I select in ManCombo is being passed into the DLookup but TypeCombo.Value always equals Null. Is this because the Dlookup returns multiple values and if so should the code be something like
Code:
Private Sub ManCombo_AfterUpdate()
Me.TypeCombo.List = DLookup("[Type]", "EquipmentTable", "Manufacturer = " & Me.ManCombo.Value)
End Sub

I've been working on this problme for several weeks, thinking about it for the last month or so, and am at a loss of what to try next. I'm working on a database for my office that tracks all of the permits we have issued. Every year our permit fees increase by the CPI (consumer price index) and the permit fee entry in the table needs to be updated (75 to 80 entries).
Rather than typing them in every year (too many chances for errors) I'd like to be able to update our fee schedule table (8 entries, look up table) and have that table update all of our fee entries in the permit table.
Any ideas of how to go about this? Thank you for your help.

I have a split database, a front for data entry and of course the back end with all the tables. I have created several Append queries to move records from one table to another (from Applicants to Students, once they are Accepted). The queries work - when I go into the tables and look, there's the data right where I told it to go. But when I open the Students input form (which draws from the destination table), the new data doesn't show up. I double-checked the destination table, and yes, the appended data is all there.
I tried running the simply query that populates the input form, and it doesn't show up in the simple query, either. I've tried Refreshing everything numerous times, tried updating the Linked Table Manager numerous times, opened and closed the program, and no dice - the data is in the table but never shows up in the simple query that populates the data input form. There's no filters on the simple query, so everything in the table should show up - but doesn't.

I am having an interesting time on a project. I am trying to create a small inventory management database with BOM (bill of materials) control.Today I am working on how to create the BOM's. In case your not familiar with inventory management, a BOM is basically a list of items and quantities used when creating a product.
Since it is possible for a single BOM to have over 200 Items associated with it, I can not have a single table with all my BOM's (fields max at 255)
So I was thinking I would be able to have a Master table with the BOM list and then create individual tables for each specific BOM.I am not 100% sure how to make this all work together but I am struggling forward on my quest..
I was hoping I could create a form for BOM management, (create/edit/delete) but since I can not keep the BOMS in a single table I would need this form to create the new table.
Is it possible for a form to create a table? or do I have to create the table first than have a specific form per table to do the editing? or perhaps a drop down selector to choose which BOM/Table I am working on.

May not be using the correct terminology here. I have a form that currently does not have a RecordSource. From this form, I want to create a table called "ICEA" with the following fields (which would be entered from the form): OperatingDay, Hour_Ending, Import, Export, and Net.Can this be done with a SELECT statement or does it have to be done through VBA?

I have two tables which are in a one-to-many relationship (the example I am dealing with is a mother and her children).
I want one form for the mother, with fields such as date of birth, and when you click Add Record I want the mother table to be updated with the new record.
However on this form I also want a field for "number of children" and when the Add Record button is clicked, not only does the table containing all the mothers get a record added, I would like XX records added to the children table where XX is the number of children entered into the form. These should have separate IDs but retain a common field that identifies the mother.

I am using a query as part of a mail merge, there are two forms that use the query, create and view, both forms use the same table. When I click the print button the query runs, and mail merges in a word document.
What I need is a filter on the query which only shows the record currently open on which ever of the forms is open, so the mail merge only happens for the 1 record you want.

I have a form and it has a field as question. I also have a field as I'd in this form from the same table that is autonumber. I want that for each field the question will be created automatically in the table as below:
Is epm ( my Id field) is created
Is epm and is created are string
They should also include Id number of each row. So It would be like:
Is epm -1 implemented
Is epm-2 implemented
.
.
For each row

All, using access 2010. I have some code to rename a table in my database. Partial Code:
Code:
TableDefs("tblMstr").Name = "tblMstr" & Format(Date, "yyyymmdd")
This works but how do I use "datecreated" to get the creation date of the table and format it. I tried to use DateCreated in place of Date but get errors such as variable not defined or .datecreated without a with block.The result I'm going for is something like "tblMstr20140603".
