Modules & VBA :: Multiple Combo Box IF THEN To Filter On NULL
Sep 12, 2013
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] ....

Hello All,
Thank you for taking time to view my access problem, I hope somebody can help / give advice on my problem.
I have a Form, within that form I have a subform. On the main Form I have several Combo Boxes.
ComboBoxes include; Year. Movie. Country.
What I want to do is when the user selects from the various values within each Combo Box to display the data in the subform accordingly.
I was able to use the Wizard to display the Movie Information correctly. The code is below for that. How can I go by doing this.
' Code to change the movie information, when they select the combo box
Dim rs As Object
Set rs = Me.Recordset.Clone
rs.FindFirst "[MovieID] = " & Str(Nz(Me![cmbMovieList], 0))
If Not rs.EOF Then Me.Bookmark = rs.Bookmark
I am very sorry if my question seems broad, ill try to be more specific upon request. THANK YOU for your time and your 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.
For example, a numeric expression may contain too many complicated elements.
Try simplifying the expression by assigning parts of the expression to variables.
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 form where I am trying to use 4 combo boxes(nomenclature,BPN,vendor, and reference) to filter a list box containing part numbers. The way I have it set up right now is in the listbox it is searching for each field and then in the criteria section i have [Forms]![myform]![respectedFieldsCombo].
This works when selections are made from the combo boxes but when one is blank (not being used to filter) then I assume it passes null for that value and the listbox doesn't return anything. I have tried to make it so the listbox ignores null values but im still having this problem.
For example: If i only have a selection for the vendor combo box then i want the list box to show all respective part numbers for that vendor, where nomenclature or any of the other fields are irrelevant. I also want to be able to stack these filters upon every new combo box selection.

I have a table with the following 5 fields. (Service Type), (Valve Name),(Size),(Rating),(Description).
I want to do two thing:
First: I want to select the required information from the first 4 fields using combo boxes and get the last field (description) based on the selected 4 fields. In other words, i want the record to be filtered using first 4 fields to give me the last field info.
Second: I want to store the filtered record (all 5 fields) in another table.

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.

I am trying to edit the below code to use 'Form_Select_Batch_Number_Form.Combo9.Value' as the combobox value to filter the records in 'Form_ Remitter_DB_Entry_Form'. I am trying to get the filtering to occur when a button on Form_Select_Batch_Number is selected. Below is my attempt to create the button to accomplish this but it is not functional and needs some work.
Code:
Option Compare Database
Private Sub Command0_Click()
DoCmd.OpenForm "Blank Form2", windowmode:=acDialog
Dim MyValue As String

On a form, I want to disable the save button, 'cmdSave' whilst the form's mandatory fields have been left blank.
I've put in a smart tag, called, 'Req' against each required field and have used the following code on the forms current event.
Code:
Private Sub Form_Current()
Dim ctl As Control
For Each ctl In Me.Controls
If ctl.ControlType = acTextBox Or ctl.ControlType = acComboBox Or ctl.ControlType = acListBox Then
[Code] ....
The save button is disabled, but it won't enable again after each field has data entered against it.
I also have this code in the AfterUpdate event in each required field:
Code:
Private Sub cboErrorID_AfterUpdate()
Call Form_Current
End Sub

I have some code in which I enter a startdate and a enddate into textbox's and a combo box where I enter a client name when I run the code it will show all record's generated with in the date range and same client name set in the combo box "cboclient" what I would like to be able to do is have another combo box call cboclient2 which will allow me to enter another client name so then when the report opens it will show me with in the date range set in startdate and enddate and filter the client field by cboclient and cboclient2 so for e.g.
startdate
01/01/14
enddate
11/01/14
cboclient
peter
cboclient2
steve
Run code show all record in date range and with client name peter and steve

I have a set of combo filters that filter one after the other as follows -
If Not IsNull(Me.NameFilterBox) Then
If Me.Form.Filter="" Then
Me.Form.Filter="Name ='" & Me.NameFilterBox & "'"
Else
Me.Form.Filter = Me.Form.Filter & " and Name = '" & Me.NameFilterBox & "'"
[Code] .....
and the I use the
Me!Form.Filter = Me!Form.Filter & " and Name = '" & Me!cboOPOwner.Text & "'"
to filter down so the user can work with what they filter, my question is how can I add on a filter that filters between dates? and second I was hoping that I could program the filters so that they could be changed individually/randomly as to filtering one after the other and then clearing to restart the filtering again ...

I am using combo box to filter records from a form. The data source for the form is from a query.
I use the combo box within the query to filter the data, I would like the form to refresh/ run the query again every time a new selection is made from the combo box.

I currently have a combo box that filters form based on specialist (an employee using the system), and this works fine:
Private Sub FilterSpecialist_AfterUpdate()
Me.Filter = "SpecialistAssigned = '" & Me.FilterSpecialist & "'"
Me.FilterOn = True
End Sub
When Specialist Assigned name is selected, it only shows their cases (records of the form that are assigned to them).
However, now I'm trying to also filter based on only the selected Specialists Open cases. I have a combo box at the bottom of the form that saves whether the Case is Open or Closed, (creatively) called CaseOpenClosed:
Private Sub FilterSpecialist_AfterUpdate()
Me.Filter = ("SpecialistAssigned = '" & Me.FilterSpecialist & "'" And CaseOpenClosed = "Open")
Me.FilterOn = True
End Sub
I've tried this based on me searching the forum but it doesnt filter at all anymore, and no error either. I've tried other ways but get errors. What is wrong with this?

My goal is to use a combo box on a nav pane to filter the following 5 nav panes with data sheet views on them. The combo shows 'component' and should filter each datasheet to only show records with the same 'component' selected in its respective component column.
What I'm currently dealing with is said component combo disappearing upon nav change, and I can't get it to filter the datasheet..but that is likely due to the fact that I cant get it to hold value on page switch.

I am using Select Case to filter a form on open and it works fine when I have this:
Code:
Case Is = 2
Forms![Open Opportunities List].Form.Filter = "[Employee] = 4"
Forms![Open Opportunities List].Form.FilterOn = True
But if I want the form to open filtering multiple employee records, like this:
Code:
Case Is = 6
Forms![Open Opportunities List].Form.Filter = "[Employee] = 2 & " And 9 & " And 10 & " And 11
Forms![Open Opportunities List].Form.FilterOn = True
I get a type mismatch error and I am stumped as to why and how to overcome.

I have a table (tblMaster). In the table is a field called Agency. The table is 200,000+ records and there are around 35 Agencies. The table grows monthly, with potentially new Agencies added all the time.
What I have been asked to do is to have a button on a Form which, when clicked, exports to Excel a separate workbook with all the table data for each Agency in the table.
I have suggested a combo-box on the Form that passes the Agency name to a query and then exports (so they could have control of which Agency to export) but no - they just want one click, spool through the table and create the 35 (or so) exports.

Custom filter I'm trying to set up. I have a data full of records with multiple columns and a form linked up to it. The form has a search box that works as well as navigation buttons.
Currently I am trying to get a filter to work. The filter will use up to five combo foxes to narrow down the fields, then return the filtered records after clicking a button. The button itself is where my code is. My issue now though is I cannot get the filter to work if I try to use more than one combo box.
The code I have at the moment is as follows:
'------------------------------------------------------------
' cmdApplyFilter_Click
'
'------------------------------------------------------------
Private Sub cmdApplyFilter_Click()
Me.Filter = "[Asset Group] = " & Me.cmbFilter1 & "" And "[Location] = " & Me.cmbFilter4 & ""
Me.FilterOn = True
End SubThe current error I am getting is Error 13: Type mismatch. I also know that the And might be the cause but I cannot change it to AND: it keeps changing back.

In my Access 2010 database there is a form with a large number of checkboxes enabling me to select/deselect certain record details.
Each click on one of the checkboxes triggers a VBA routine setting true/false values in one of several tables linked to the main table.
A query over all records is filtered by the true/false values of the linked tables and the resulting set of records is displayed in the (continuous) form.
The header of the form contains a text field with the value "=GetRecCount()" displaying (correctly, but randomly fast) the number of records selected:
Code:
Function GetRecCount() As String
Dim NumRecs As Long
Dim rs As Object
On Error Resume Next
Set rs = Forms![Super Search].RecordsetClone
rs.MoveLast
NumRecs = rs.RecordCount
Set rs = Nothing
GetRecCount = Format(NumRecs, "##,###")
End Function
Now, the funny thing is that each click on one of the boxes results in 1 call of the VBA routine setting table values, but 21 calls (!) of the text field "=GetRecCount()" in the form. I have established this by incrementing a public variable at each pass.
Why a field in a form is updated 21 times when a filter is applied?

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

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 have a form that is showing data from 1 table. That table has 12 different fields on it and I want to be able to filter based on selections I make in a combo box in the header of the form. The filter string must be dynamic enough to allow filtering based on 1 criteria selected, or multiple criteria selected. For example:
If I have values in filter fields 3, 5, and 9 I'd want the filter string to be created as follows:
"...WHERE field3 = field3filter.value AND field5 = field5filter.value AND field9 = field9filter.value"
If I have values in only field 7, I'd want th efilter string to be created as follows:
"...WHERE field7 = field7filter.value"
And so on and so on.
I have created some filters before but all of the different VBA syntaxes I'm using seem to come up short.

Hi!
I want to be able to filter a form based on a dropdown box, where one of the items can be null. (The field is of type short date).
the dropdown box is named "Fltr1".
The form is based on a query, and i have tried to express the filter in the query like this (sql syntax):
([Tablename].[Columnname]) Like "*" & [Forms]![frmMyForm]![Fltr1])
But this way, the records with this column being null are omitted...
I very much appreciate any help that leads me in the right direction ;)
thanks

Can't figure out the syntax for specifying a null value for a text or combo box when filtering a table via a form. "Is Null" seems to work for query criteria but doesn't work for form controls. If one right-clicks on a form control displaying a null value, one of the choices is "Equals Blank" which if selected works fine but what does one use for the text filter if the record for the control in question does is not displaying a null value?

Hello Everyone,Been a while since I needed to post on this forum, but I found something rather disturbing today; either that or I have missed something obvious. I have a large query of financial data, and I filter out certain codes which I don't want to include. The filter is;<>"BL01" And <>"SS01"Which works as it should, filtering out all BL01 and SS01. However, it also filters out any NULL values, which is something I would not expect it to do. When I enter NULL as a filter, I get the records I expect. What am I doing wrong here? I am using Access 2003 SP3 on Windows XP Service Pack 2
