List Box With NULL Option?
Dec 29, 2014
I have a table for holding client responses to a questionnaire. 10 of the fields in this table are List Boxes with options "Yes", "No", and "Blank/Other". The "Blank/Other" option is supposed to be reserved for forms handed in where the field has been intentionally left blank. If the form has not been handed in at all, I want the fields to just be NULL. The problem is that if someone accidentally fills out information for a row that should all be NULL, there is no way to correct it. I have tried adding NULL (no quotations) as an option in the list box, but this does not work. I have also tried adding "" as an option, but no luck there either.
How do I add an option in a list box to leave a field NULL?

I thought this would be easily found by searching the forum! But I had no luck.
Having trouble with an Option Group. I have an option group with 2 options, YES and NO. Value of Yes set to -1 and value of No set to 0. The field this is bound and is set to Yes/No. The problem is.... No matter what I try it keeps assigning a value to this field in my form! The option group is the last item on the form. Date being the first..... After you enter a date, and an auto number is created, it gives the option group a value of YES or "-1" There is nothing in the default value of the radio button, the frame, or the field to which it is bound. Why is this assigning a value and how can I stop it???? This group needs to remain blank to force the user to THINK before it has a value.
I have managed to get around this by changing the bound field to "Number" instead of a "Yes/No" .... But I am concerned with future queries and filtering. So is this the only way around this problem? Setting the field to "Number"?? And where is it pulling the value of the option group from when I have everything set to null??
Thanks

I have a form with 6 option groups, each with 2 option boxes (-1 & 0). They are triple-states and start off in null mode with a validation rule of "Not Null". The idea is to ensure the user has decided something for each option group before being allowed to save the record.
The problem is that each time I load the form, the first box I select, all the others then default to the same option (no longer null).
Any Ideas?
Thanks,
Ben

We just upgraded from 97 to 2003. Just a few little issues.
We have an option group.....3 different toggles. One is supposed to bring up incomplete records by check if the 'end time' field is empty:
ElseIf Frame240 = 3 Then
Me.filter = " [End Time] = Null"
Me.FilterOn = True
It worked in 97 version. Nothing shows up now in the 2003 upgrade version.
Any ideas

Some background: I posted last week seeking help starting my first access project. I am trying to create a database that will allow me to enter every employee in our company along with their foreign language skills (and other skills) that they have.
Then I want to be able to create a form that will allow me to search for all the employees that have a certain skill combination (or better) that I am looking for.
Thanks to a lot of help from this form I was able to make a lot of progress.
I have three tables. One table with employee name and number, one for language/skill and language/skill number and a junction table that I want to query.
But now I am stuck on what I believe is the final step; Creating the form control that will query my junction table.
Can someone get me started on how exactly I can implement this? Is a List Box my best option?
Do I have to code it in SQL? How do I do this? Any beginner tutorials online? I couldn't find any.
I had a combo box that allowed me to search for ONE language/skill and that worked fine but I need to be able to search for employees that have combinations. Do I need a List Box for this?
Because I will in the end have about 20 languages+skills in the list I was hoping to use checkboxes on a form.
In this way I could just check next to all the skills I want, hit the control button and it would return everyone that met the requirment + anyone that exceeded the requirement. This seems better than a long list box with 20+ options.
Any ideas? I will attach my project and would appreciate help.
Thanks!

Can anyone point me to where I might get help setting the above up. I have a list of unique enties in a query, and have set up a global variable so that on my form when I choose an option from the list only data relating to that option is pulled back from a number of tables/queries and output on a report. I would like to be able to get the data for my full list of options. I'm afraid I'm lost here. I don't know of any way of setting my variable to 'ALL'. Is this available in Access 2000? I have Access 2002 at home but I need to work on a PC that only has Access 2000, so I have kept it as a 2000 database. All help appreciated.

Hi,
I have the following say;
tblProducts:
Name
Categories
Price
tblCategories:
Name
IDNumber
at the moment, no relationships built
tblProducts "categories" requires the IDNumbers of the categories in tblCategories - there are mutiple IDNumbers for each product, and they need to be seperated by a comma - for example ProductA has categoryIDs 1,3,6 (where categories 1,3,6 and called A,C,F)
At the moment, I am having to manually look up what each categoryID number is by CategoryName, and then type it in the tblProducts category field.
I want to have a form which provides the tblProduct "Name" and then a long list of all the tblCategory "Name" contents as option (or tick) boxes. So all cateory Names listed.
Then when I tick mutiple boxes on this form for the categories, it populates the tblProduct "Categories" field with the tblCategories "IDNumber" codes, with a comma between each one! (so the names chosen actually populates with the ID number)
So basically if on my form, ProductA has category A,C,F ticked -- so the field tblProduct "Categories" is "1,3,6" (where 1,3,6 are the category IDNumbers and A,C,F are category names)
In other words, I want to be able to choose the categories for my products by choosing the Category Name (rather than ID) but having the ID populated into the relevant field -- I can do this with a combo box displaying a different field to that thats populated....but this only allows one selection....
I want mutiple categories to be chosen (via the form with option/tix boxes), and thus to populate the relevant field with commas seperating.
Is this last bit possible?!!
How!
thanks in advance

This is probably something already talked about, but if i have a combo box that has an "Add New Entry" selection in it, and when the user clicks on it, i want to add what they want in to the table that the combo box chooses from. can I have that "Add New Entry" selection open a form with a text box, and then have that value enter into the table? What is the easiest way to do this?

I was checking if it is possible to add a text option after creating Look Up Tables, and I am also getting extra spaces while creating lookup tables where the drop down list goes more than 100 items.

how I can have a shortcut option when right click on each item on the list box. So I got my answer with below code that opens another form "frmshortcut" with a listbox inside that shows list of options like "new task" , "edit item" . Now my problem is (like attached picture) the shortcut list (frmshortcut) will be open in another place when I right click the mouse, it is far from location of click. Also it shows some default in access when I right click in the listbox ("subform", "cut", "copy"), actually I do not like it shows these, just I like it shows shortcut list I have defined by the list box.
Private Sub ItemList_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single) Const RIGHTBUTTON = 2 If Button = RIGHTBUTTON Then DoCmd.OpenForm "frmshortcut"
' DoCmd.OpenForm "frmshortcut", acNormal, , , , acDialog
Forms!frmshortcut!txtparameter = Me.ItemList.Value
End If
End Sub

I have a simple data entry form with drop down facilities on 2 fields. One of these fields incorporates a drop down list from a table but there are occasions when I wish to make a free text entry for the single record, but do not wish to add it to the drop down list.
I have tried to achieve this with a Combo Box but without success, although I am sure that I have read that it is possible.

I have several comboboxes in my database from which users select values. However, in most cases, I do want to give them the option to add an item that does not appear while simultaneously updating the underlying table which stores those dropdown values. I have made use of the builtin "allow edit list items" feature of Access 2007 but the form always opens on the first record of the form on which they are to add the new item. Is there a way to specify that it should open in Data Entry view apart from using VBA?

I have a table that has several fields that contain a date if a user is licenced to use a certain piece of equipment and is null if not. Each recor has other data in it such as name, and a unique identifier (numeric). What I want to do is make a list of the fields which have a date in them to create a licence for what they can operate. Any help on which way to go...pretty new at access.

I am using an Access database for a foreign language dictionary project.
One of the forms I use is populated by a query (qryLemmaTable) to retrieve information from tblLEMMA.
This form works precisely as I intend it to work, but there is a glitch on it that is driving me mad.
The form in question has an option group with 11 radio buttons that correspond to the parts of speech associated with each word in tblLEMMA.
When I click on the button optAdjective I apply a filter and the only records that are displayed are adjectives. (The same applies for Nouns, Verbs, Prepositions etc.)
Here is the glitch: even though the radio buttons apply the filter correctly, no “black spot” appears in the button. Other signals on the screen let me know what word type is selected, so I can accomplish what I want, but I want the “black spots” too!
Perhaps this will be a clue: For each radio button I use the following code in the GotFocus event.
Me.FilterOn = False
Me.Filter = "wordtype = 'A'" ‘(or N, etc)
Me.FilterOn = True
And this for the Lost Focus event
Me.FilterOn = False
Thanks for the help.

Hi
I've got an Option Group with 3 options; Yes, No and Future.
I also have a range of Check Boxes; 1 for every day of the week.
When one of the check boxes is selected I want the Option Group to change to Yes.
Currently, the Option Group defaults to Future and No will only be available by manually selecting it. This doesn't need to be changed.
Any help will be greatly appreciated!
Cheers

I stumbled upon the Option Group function just yesterday and, happy as a clam, I created a group with 2 options in radio button style. I assigned the values to a field called Registration_Type as the 2 options are "Confirmed Registrants" and "Prospective Attendees".
[Great. That part works well. When I look at the table, a 1 or a 2 is in that field so it's great to know how to control accidental ticking of radio buttons (previous 450 records or so didn't have this option group functionality so one might easily tick one of the buttons. So one part of controlling option group I know I can handle via the table itself for now.]
The challenge is how to ensure the user always ticks one or the other ... I went back to the main table and tested the 'required entry' option for the Registration_Type field but forcing an action like this is not ideal in my mind. The usual error message vagueness for the average user is no good and I don't want to limit the user so much.
Is there a way to simply have a popup come up warning that neither radio button was ticked? Perhaps something linked to the form - i.e., maybe "after update"?? I only learned about attaching code to before and after update on controls a couple of days ago, so not sure if this would be best approach.
Just something to let the user know that nothing has been ticked in the option group as that controls in which of 2 reports the data will show up in so any record not ticked might mean a registrant being left out, which would be rather disastrous <g>.

I do not understand what is happening here. I have foll0wing line in a calculated query field:
m: Switch([EmpID]<5,1) ' run Query 18 in attached example, A2007/2010
this produces 1 for all EmpID<5 and Null for all other EmpID's. All as expected.
But if I do this:
m: Switch([EmpID]<5,1,[EmpID]>=5,Null) ' run Query 19 in attached example
then the entire column is set to Null

It might be an easy one but I just wasted the past hour deciphering through my code in order to solve the run-time error '94' that I'm getting when trying to execute the following code:
Code:
Private Sub cmdUpdateDates_Click()
'###################################
'This sub aims at combining the timesheet date and the start and end time into the fields [Start Time] and [End Time].
'###################################
Dim intCounter As Integer
intCounter = 0
Dim rs As ADODB.Recordset
[Code] ....

Hello all,
A bit of a weird one, I've got a query and the criteria for showing records is that one particular field is null. However the query is showing records with the values in the field chosen for the Is Null.
Not sure why this is happening, has anyone come across this problem before?
Thanks.

I am having problems with setting up a set of combo boxes.
What I am trying to do is if combo Productline is empty then in combo PartNumber would show all products but if combo Productline has a value selected then in the combo partnumber would only be able to select the partnumbers in that productline.

I think the title pretty much sums it up....
I have a query where data is first sorted by user input; first field's criteria: [fieldname], then by another field's criteria: Is Null.
I know there are records containing null values in the second field, as I have run a select query with the criteria: Like "*", to make sure they are null, and not zero-length-strings.
The query is refusing to return any results...
Any ideas?

In my access form I provide the user a list of locations from various countries in a listbox . But the list is too long so I provide him a combobox for selecting a country. Selecting the country should update the listbox showing only the locations in that specific country.
So my SELECT from the listbox must cover the unselected state and show all entries and when a country is selected it must narrow the selection.
I tried to get this happen with the following SELECT statement containing a variable. Choosing a country in the Combobox results in a change of the variable and in a requery. This works after the first country is selected and for each country change, but the initial list is empty.
VBA in the loadform
'Application.TempVars.Add "varcountryselect", "*"
SELECT in the listbox "lstlocationsperproject"
SELECT tbllocations.locationID, tbllocations.country, tbllocations.localstreet, tbllocations.localcity FROM tbllocations WHERE ((tbllocations.country) Like [TempVar]![varcountryselect]);
VBA in the combobox
Application.TempVars("varcountryselect") = [Form]![kombcountryselect].Column(0)
Me.lstlocationsperproject.Requery
The values in [kombcountryselect].Column(0) are texts like "SPAIN", "MEXICO", etc.
Any hints, how I have to use the * for getting the complete list on the initial view ?
