I have a form, form1. Inside there is a combo box, cbo1, that gets its values from table1.On form load, I want an expression that checks if table1 has any values to "send" to cbo1. If yes, meaning, if after form loads cbo1 is loaded with table1's values, I want cbo1 colored RED, if not, colored WHITE.

I'm working on a table for work which will serve as a database of bins and the products currently in those bins, as follows:
ID Bin Amt Product
1 34 25 110001
2 33 15 200005
3 32 23 110003
etc.
Basically: employee A will use a form to update "Bin 34" (ID=1), with information (Amt, Product) until it is emptied by employee B and cleared using a separate form. No new records will be made or deleted, just the adjacent fields (Amt, Product) cleared and filled in and cleared again over and over.
What I'm trying to figure out is, when employee A clicks on the combo box on his/her form to select a Bin and enter information, how can I filter what is listed in the combo box to display only those bins which have no values under Amt & Product. The real-world risk of overwriting a bins fields before it has been cleared by employee B (who physically empties the bin) can be extremely high monetarily so I am trying to reduce that risk by eliminating it from the combo box until employee B has cleared those fields.
In a previous post someone mentioned a difference between Null and Empty. Is Null is not pulling the nulls but I know those fields are empty. Can someone tell me how to pull in these empty fields. for my calculation I need to get Companies that showed revenue after and didn't show revenue once their contract started.
Thank you
I have the following problem:
I have a make table query that sum a total amount in order to have only the total in the table field.
However, when the total is 0.00, the make table query says "you are about to pos 0 rows" instead of postin 1 row with 0.00.
How can I set the query in order to have a 0 in the table when the total is 0 instead of having nothing posted ?
I have tried the is null, is empty, is missing, nz and nothing seems to work.
I have the query below and it returns the number of cases for eache of the case status (open, closed or private) Some of the cases have no status, the field is empty. Is there a way to count the number of cases which have no status in the status field?
Can someone tell me how to do this?
SELECT
Count([Report table part one].CaseStatus) AS CASES,
[Report table part one].CaseStatus AS STATUS
FROM [Report table part one]
GROUP BY [Report table part one].CaseStatus;
I have a module that creates records into a contacts table in my access database. When there is no data in the field from outlook, the data is populated as an empty string "" instead of a null value, creating problems with subsequent queries and processes. I'd like to create the data as a null value but the module keeps failing with "object is required" on the statement
rstImport("Customer ID").Value = System.DBNull.Value
It doesn't seem to like System.DBNull.Value or DBNull.Value, and when I assign the vbNullString constant instead, it gets set to "" again and not null.
We just upgraded to Office 2010 from 2003 and I am now getting 'invalid use of null' after choosing a valid combo box option. When I debug, the line that highlights has to do with a text box on the form rather than the combo box. Here's the code highlighting:
frmLines = Me.WorkLoadUnit
This is the code in it's entirety.
Private Sub fsubProductivityInput_Calculations()
On Error GoTo err
'Calculate Breaks and Net Hours
Dim frmLines As Double
Dim frmHours As Double

I have a combo box in a form which simply pulls a text field from a single table - approximately 100 values to choose from. On the After Update Event, there is a basic "If null this, else that" VBA which just hides a subform if the value is null. This works fine, except there are a handful of values (I've found at least 6) that when chosen, trigger the NULL portion of the code! All the values are very similar, so I don't know what the problem is - for example, the value "D-11" works, but neither "D-10" nor "D-12" does.
View 11 Replies View RelatedIm trying to concatenate a bunch of fields (50 arghh) which each are either blank or just contain one letter. This was someone elses setup for an attendance register which I think is an odd way of doing it. I would have used one field and then to get the mark for a week take a substring at the appropriate position. Anyway im trying to replace an empty string field with a letter to represent the register hasn't been marked using sql statement:
SELECT [400 Student Marks].acad_period, [400 Student Marks].student_id, [400 Student Marks].register_id, [400 Student Marks].register_group, Replace([1],"","U") AS attendance
FROM [400 Student Marks];
[1] being the first register week then I would have concatenated with [2] etc...
This however causes an error each time on the attendance field so im guessing replace doesn't work on empty strings. Is there a way round this/alternative.
Thanks for any advice.
I am assigning a recordset using vbs code. The variable "CB_proj" is a combobox value. The problem comes when the combobox is null, the program errors out and even if I try to exit the routine with an if statement, it still compiles the line of code and errors out because the object doesn't exist. how I can get it to not compile that error if my combo box value is null?
CB_proj = Forms!CC_MAIN.CB_proj
strSQL = "SELECT " & [CB_proj] & ".* FROM " & [CB_proj] & ";"
Forms!CC_MAIN.projdat.Form.RecordSource = strSQL
Forms!CC_MAIN.projdat.Form.Requery
Forms!CC_MAIN.Form.Requery
I have a SQL Server 2005 backend table with a varchar(1) field which allows nulls. The field is populated from a combo box in Access 2012. The field can be set to 1,2 or 3 via the combo box or left blank in which case its value will be null. Sometimes I need to reset this field to null. How can I do this via a combo box? I know I could just set this to an empty string but this would mean re-writing a load of queries which a looking for a number or null.
Something like 1;"First";2;"Second";3;"Third";Null;"Blank"
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.
Hey guys......simple problem
I have a form with 3 combo boxes.
The 1st combo, called winecode, gets the values from the following sql:
SELECT [winecode] FROM wine WHERE winedesable=0;
it works.....
The second combo box, called suppname, gets the values from another select, but depending on the previous combo:
SELECT DISTINCT [supplier].[suppname] FROM supplier, suppwine WHERE [supplier].[suppnumber]=[suppwine].[suppnumber] And [suppwine].[winecode]=[Forms]![addpop]![winecode];
it works......
The 3 rd combo, called winesubcat, gets the values from a query which takes the selected value from the previous 2 combos. The query works by it self . However, i added the query in the data tab and open the form. then i selected values from the first 2 combos and there is no value in the 3rd combo...... any idea??
thx max.
When I click a button I have code (below) that checks to see if my Combo boxes are NULL (empty), and if they are it’ll prompt the user to “fill in all fields”. Right now it includes all of the combo boxes on my form. Although, I want it to only include 3 combo boxes (I have 5 on my form). How could I do this, lets say if my combo box names are cbo1, cbo2, cbo3 ?
For Each ctl In Me.Controls
Select Case ctl.ControlType
Case acComboBox
If ctl.Value & "" = "" Then
MsgBox "You must fill in all data fields."
Exit Sub
End If
End Select
Next
Hi All.
Hope someone can help.
I have a form with 2 combos (cboStart and cboEnd) and button to preview a report.
The report is made from a Query, with the following in the completion date:-
Between [Forms]![frmReporting]![cboStart] And [Forms]![frmReporting]![cboEnd]
The user then chooses the start date and end dates in the combo's.
What I would like to do is have a message box appear if the use forgets to enter either date.
Many Thanks for reading this.
Frank.
Does anybody know how to add an option that says 'none' or 'no selection' or something to a list of combo options.
I use a query by form to produce a report. But I may close that report and it goes back to the form. If I want to re-run a new query I have to close the form and re-opne it so the combos are empty.
Is there anyway to have a 'none' option to empty the combo box?
Hello,
Since the last Windows XP update on the secretary PC, all combo lists are now empty even if the related tables are not at all.
Here is her configuration:
Windows XP SP 2
Access 2003 SP 3
Here is the description:
1) I've got a combo list based on the table Towns with zip-code, name, country.
2) In the form, in addition the combolist is sorted on the name, just to easily pick up the right Town
3) Since the Windows update, the combo list displays only the zip-code, the other fields are empty even if the table content is not empty at all; I mean I checked in the table content itself.
4) I created a query based on the same arguments of the combo list and the query is working well alone; if I try to create a new combo list linked to the query, then I get the same weird result
5) I've tried to create a new field with the combo list assistant; when I select the table Towns, it shows me the full content (so name, zip, country) and when I run the form, the combo list is again almost empty !!
6) What is more weird is that when I put the Access database back on my standalone laptop which is running Access 2002, the combo list is working correctly !! In fact I am currently maintaining the Access database from my Access 2002 since more than one year and I had no issue
7) In fact, I got the same issue with all the combo-list in my Database
8) I tried to compact the DB but with no effect
Somebody has a brillant idea for me ?? otherwise I think I will contact Mister Bill directly :)

I have field in my table, which is required (in access, or not allow null sql server), and have defaults of 0.
I have a form with a combo box bound (thru query) to this field - how do I let the user choose something from the list and then decide they actually didn't want to choose anything - and so clear the list.
Hear I get an error saying the field cannot accept null - how do I just force it to accept 0 - ie no choice??
Thanks
Hello!
Looks like a grate forum for access topics and thats exactly what I need now! I'm new to Access and are going grazy!!
I'm trying to add some functions to an excisting database that someone else has done.
The Form creates an report from an db containing a one per day status information from water and electrical meters. Filling in start and stop dates gives a nice report over all meters and their status.
Now I want to add a combo box so the user can select one meter or leaving it empty to get all meters. I can make it work when selecting one meter in the list, but leaving it empty shows none. Or selecting any don't help all of the meters shows up anyway.
I used the search engine on this forum and found similar problem, but couldn't figure it out. Tried many combinations of the IIF statement, but didn't help.
Please help me!!

I'm using a form for book drinks to a customer room.
To find the customer, I'm using an search function (Unbound field), works fine.
The same function I'm using in the subform, for booking the articles to the customer.
Now, I'm wondering, is there an easy way to clear the search field either when starting the form or after the search is done and the article booked.
The search function is based on the macro (Search for record, condition: ="[ID] = " & Str(Nz(Screen.ActiveControl,0))).
Hello All,
I’m using a combo box for the criteria for a saved query. Is there any way to show all the records if the combo box value is either “0” or null?
Thanks,
I have a form that using a combo box to select specific record, sometimes we need to see all records, i would like if the combo box if left empty to return all records. I typed this expression but it returns no records when combo box is empty.
IIf([Forms]![FrmReports]![LoanOfficer]="IsNull","*",[Forms]![FrmReports]![LoanOfficer])
If i use this expression i get the wrong results when a Loan Officer ID is enterd;
LIke([Forms]![FrmReports]![LoanOfficer] & *
Example of wrong results, if Loan officer Id is 1, then it returns loan officers 1,11, 111
Thanks in advance for any help

I can't seem to figure out how to test a combo box null value.I try:
Code:
If IsNull(Me.cboManufacturer) Then
MsgBox ("Please select category")
Else
DoCmd.OpenReport "rptItemCategory", acViewPreview
End If
This works if the combo box IS NOT NULL, but if null it gives me:
PHP Code:
Run-time error '3071': This expression is typed incorrectly, or it is too complex to be evaluated.Â
For example, a numeric expression may contain too many complicated elements.Â
Try simplifying the expression by assigning parts of the expression to variables.Â
I then tried:
Code:
If IsNull(Me.cboManufacturer.Column(0)) Then
MsgBox ("Please select category")
Else
DoCmd.OpenReport "rptItemCategory", acViewPreview
End If
This works if the combo box IS NULL but if i've made a selection, it still gives me the message box as if I've selected nothing....
I have a main form with multiple combo boxes that filter a subform datasheet. In my main form combo box [PR_Filter] I added a selection titled "<Blanks>". When I select "<Blanks>", I want it to filter my subform field [PR] for NULL values. If I select anything else I want it to filter on that selection. I cannot get the NULL filter to work.
Here is the code that I have (Red is the field I need the NULL values):
Private Function PurchaseFilter()
Dim strFilter As String
Dim bFilter As Boolean
bFilter = False
strFilter = ""
[Code] ....
I want to pass the Combobox value of one form to a textbox on another using the where condition. Using the break in VBA, the value of the combobox (in this instance "two") shows as null. the control of the combobox is [cboSubCategory] and I want it's value to pass to another form "tblCategoriesSub" (aware of the incorrect reference, as used wizard quickly - but will change if I can get it to work) to the "SubCategory" field.
