Forms :: Boolean Checkbox Updates
Aug 4, 2013
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

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 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.

The problem is that the software works for all locations execpt one that is in austria, after debuging I found out that there is a statement in the code that uses boolean true or false, the only way it worked is when I put an if statement with false or true as string, ex: if doc = "true" then
buttom line has anyone faced this problem, I searched microsoft website and they said that some vb engines don't convert boolean to string. Please Please if someone has a clue try to help. Thanks.

I have a search tool, but right now it is 100% case sensitive in the sense that if i search for "test" and my entry is "Test" it will not return any results.
is there any way to setup so I could say search for "Test" and it would find "test" properly? Or even to the extreme where I searched for "Tes*" and it came back with the "test" entry.
Thanks,

I need to create a user interface that will allow a boolean type search of a field. This would mean item1 AND item2 AND NOT item 3, item1 or item2, item 1 NOT item2, etc.
I've set up a combo box setup with the following script, but I can't figure out how to adjust it to allow the multiples.
Please advise if I should adjust this or try a differenmt interface format for my users.

I have an Access 2010 db which has a load of global variables of type Boolean. The values are different for each machine the database is stored on, so I have a linked table to a separate Access mdb. On startup the database opens the linked table and assigns values to each variable.
However I need to differentiate between a valuable value of False and the variable having not been set. As boolean variables default to False, this is a problem. One option is to use data type Variant, but I know this is not efficient. I am considering using data type Byte instead of Boolean, with 1 as False and 2 as True.

I have a continuous form that has several checkboxes in it. Only one is initially enabled and I want the first to impact if the others are enabled, but only in the currently selected record.
I tried VBA but quickly found that this enables/disables the checkboxes in ALL of the records. Next I found out about conditional formatting--which does exactly what I want, but only works on text boxes and combo lists.
Is there any way that conditional formatting can be used to impact (vs. be impacted by) a checkbox?

I have a subform in datasheet view. In the main form I have various combo boxes to filter the data in the subform. I want to be able to check off the checkbox in the subform then filter all records that are checked, however, I am not able to check any of the checkboxes when I'm in my main form.
Example:
Sales Region, Order Date, are two fields
I can go in and select "north", "5/20/2013" then filter and let's say I get 55 records
So within the north region on 5/20/2013 I only want to select 5 of the 55 records by checking them off in the subform then in the main form I would drop down the unbound combo box to 'yes' and it would give me all records in the 'north' region with an order date of '5/20/2013' that I checked which should be 5 in this case. But, it won't let me check the box in the subform.

1. In a form that I have created, I have a checkbox that I want to have checked when the form (ticket) that was filled out has been completed by our company. I want the checkbox to only be accessed by us. How do I achieve this to only certain users have access to check that box?
2. I have a main screen that the form is able to be accessed by. In that home screen I have a query that shows what tickets have not been completed (checked). How do I get those tickets that have been checked, to not show up on that screen?

I'm having a hard time with this (what I thought) was a simple filter. I have an unbound checkbox (chkFlag) and an unbound text box (txtfilter). The filter was working fine till I decided to also try to filter on the checkbox.
I'm trying to filter records that either have either a check in the [Flag] field or have some part of the text in various other fields. The problem is I can get the records to filter if the checkbox is checked or on text in the various fields, but not both. I've tried using AND and OR, but it's not working.
Code:
Me.RecordSource = "SELECT * from tblContacts; "
'-------------------
strWhere = ""

I am new to access forms. I am trying to use the 2 checkboxs for my make table query.
Future cost checkbox and marginal cost checkbox.
If future cost is checked, then I want 00 as criteria for the field cost type in the query, if marginal is checked then 01. If both checked, then I want both.
Seems like a iif statement is not working in my query. I am trying to create an event now but I do not understand the VB codes.

I have a table, it is an on going update for a meter reading. When the last record for a particular meter is closed, a new record is created with updated information and carry forward numbers. Something like this:
Meter# - Opening - Closing - Active - Date
123 - 1776 - 1876 - No - 2014-Jul-04
123 - 1876 - 1976 - No - 2015-Jul-04
123 - 1976 - 0 - Yes - 2016-Jul-04
This is in a table form for the user to see the old data, and be able to edit the last line only. My problem is how to I tell access that that can edit only the last row? Since there are 1,000's of meters involved this is not going to be the last line of the datatable nor is it a new record. The trick is the use can edit only rows where the Active field is True. Once set to false the record should not be changed any more.
