I have a small table of items that will not be changed. For each item entry in the table, there is a yes/no value that I want to bind to a checkbox in a form. The problem is, it seems like I can just bind to the column, not to specific entries in the table. How do I bind a checkbox to each item in the table?
I'm using Access 2010.
Set up your form using the 'Continuous Forms' option in the Form's format default view. You will see each record in the table with individual controls for each field.

So, I had lookup fields on my tables. I have recently learned that this is a bad idea. So, I'm trying to convert them to lookup fields in the forms that fill those tables.
The lookup list is drawn from another table with the individual values. On the table, I went into design view under the lookup tag and changed "combo box" to "text box." The fields that were previously lookup fields now display the "key" of the item that was displayed previously in the field.
The form still shows the correct lookup value but the associated table no longer does it instead shows the number associated with the value and not the value. What do I need to do to fix this.
I guess my question boils down to not knowing how to link a lookup field in a form to a text field in a table.
You don't need to change your forms, just update your tables - change lookup from combobox to text box, you did this correctly.
Existing forms should work as usual, with comboboxes, settings for those comboboxes were copied from table settings and not liked to table settings anymore.
In new forms you'll need to do the same manually: after placing the field to the form convert it to combobox then setup correct Row Source, Column Count and Column Widths properties of combobox.
There is access datasheet sub-form and users should only be able to edit count column. How can that be done ?
Currently, If I change the form property Allow Edits = True, users can update any cell.
Also, the user should be able to enter different count values. If a user types 1 in first cell, it get copied for all the rows.
How can this be achieved?
For each control on the form that you don't want editable, set the Enabled property to False (or the Locked property).
For the count copying to all rows, we need to see the query that this datasheet is based on to answer that. If the count is an unbound textbox, you will get the behavior you are seeing as Access will only create a single instance of the control, then repaint that single instance across all rows (note that this is the same with continuous forms as well)
Instead, create a query that has this field (or a dummy table) and bind to that, making sure to bind the textbox to the dummy field, and then you should be able to edit the value on a per-row basis.
I have a form setup in Access that contains many input fields and dropdown boxes.
This form doesnt contain an insert button. I just click on 'add record' at the bottom of the window.
Now I`ve add a multiselect box which contains multiple values.
I want the form to insert the selected values from the multiselect box along with all values from the other input fields in the same row if possible.
For example; the column that holds the multiselectbox values needs to contain 1,2,3
Another option is to store these values in a different table as long as I can join both tables when generating reports later on.
Any pointers are appreciated
You have two options. Either way requires a table structure like this (called a many-to-many relationship):
Option 1 is to make a subform which has a combobox on it. The subform is bound to this cross reference table ParentTableLookups and the combobox's control source is ParentTableLookups.LookupStoreValue and Rowsource is the Lookups table.
This is much less code and doesn't require a save button however it does mean that in order to see the things a user did not select they need to open the combobox. Maybe not quite as visually complete as the listbox.
Option 2 is to use the same table structure but instead of a subform you fill in a listbox on your parent form from Lookups. Then you iterate over ParentTableLookups where ParentTableLookups.ParentTableId = your current record and for each ParentTableLookups.LookupStoreValue you select that in the listbox.
In the parent form's AfterUpdate and AfterInsert records you need to repopulate ParentTableLookups based on the selected listbox values. You can create the records using DAO easily.
I have a combobox query that uses parameters from a parent item. When I first load the form the combobox is empty, if I go to design view and return to form view the combobox is populated with the correct items.
While searching for the cause of this I decided to create an extra text field that retrieves the same data from the same parent item. On the first launch that textbox is populated while the combobox remains empty.
My last step was to change the combobox query parameter to refer to the newly created textbox. After that the previously working textbox started out empty as well and became populated after going to design view and back.
My hypothesis - the query tries to retrieve the parameters before the text fields are filled. Keep in mind I have reversed loading order of main-form and sub-form as explained here.
I don't know what to google for any more
You can requery the combo in the current event of the main form like so:
Me.Subform1.Form.MyCombo.Requery
I need to display certain record (all the fields in the form populated according to that record in the form) according to textbox in form. Is there a way for me display that record without using filter or vb code? Do i need to design a query for this?
Yes you can put an unbound textbox (or combobox) in the header of the form. Then change the recordsource of the form to a query, just click the elipsis (...) next to the table name in the record source property and access will open the query design window for you.
You need to add all the fields to the query and in the Criteria row of the field you want to select by right click with the mouse and select "Build". You will be able to select the unbound textbox.
