I have a checkout form with two unbound combo boxes- frame ID and Project Name, and a button - Assign Frame.
The Assign Frame button has the following working code to update the StockFrames table:
Private Sub AssignFrame_Click()
CurrentDb.Execute "UPDATE StockFrames SET ProjectID = " & Me.Project & _
" WHERE FrameID = " & Me.FrameID
Me.Project.Value = Null
Me.FrameID.Value = Null
End Sub
I want a message box to appear if a user tries to assign an unavailable frame to a project: "This frame is currently assigned to another project. Are you sure you want to override? Yes/No"
I know this needs to be an if/then statement involving something with StockFrames.ProjectID <> Null.
Also, should this be a BeforeUpdate event or better suited somewhere else?
Use DLookup or DCount to first check if frameID is already in use. Code can go in Click event.
If IsNull(DLookup("ProjectID", "StockFrames", "FrameID=" & Me.FrameID)) Then
CurrentDb.Execute ...
Else
MsgBox "your message here"
End If
A better option may be combobox RowSource that does not include FrameID values already in use so user can't even choose them.
SELECT FrameID, FrameDesc FROM StockFrames WHERE ProjectID Is Null;
Then requery combobox in Click event.
Be aware, conditional combobox does not work nice with bound form in Continuous or Datasheet view but since you appear to be using an UNBOUND form, that should not be an issue.

I want to open a form to the record selected in the subform of a different form. I've tried following what I’ve seen in other posts about this, but I still can't get it to work. I think I'm just missing some very basic detail but this is my first Access database and I can't figure out what it is. Thanks in advance for your assistance.
Details:
F_Detail - (This is a Single Form containing details on a project.)
F_List - (This is a Single Form containing a subform and a button.)
subF_List - (This is the subform contained in F_List. This subform is in Datasheet view)
Project_ID - (This is the primary key contained in subF_List and in F_Detail. It is the common criteria between the two. It is Short Text type.)
subF_List displays row after row of projects. F_Detail displays details about a single project at a time. From F_List I want to select a row in subF_List and then click the button to open F_Detail, and F_Detail will be displaying details of the project whose row was selected in subF_List when I pressed the button.
What I Have for the Button:
On Click > Event Procedure
Private Sub ProjectDetailButton_Click()
DoCmd.OpenForm "F_Detail",,,"Project_ID = " & Me.Project_ID
End Sub
Upon clicking the button, I get an error saying, "Compile error: Method or data member not found" and it highlights the .Project_ID at the end of my code.
I don't know what I'm doing wrong and would appreciate any help you can lend. Please let me know if I've left out any needed detail.
Use apostrophe delimiters for text field parameters. Use # for date/time, nothing for number.
"Project_ID = '" & Me.Project_ID & "'"
Me is alias for form or report the code is behind. To reference a field in its RecordSource:
Me!Project_ID
Code on main form referencing field on subform must reference through subform container control. I always name container different from object it holds, such as ctrProjects:
Me.ctrProjects!Project_ID
I name controls different from fields they are bound to, such as tbxProject:
Me.ctrProjects.Form.tbxProject
I have two Comboboxes on a from: txtKategorie and txtTyp.
The values for the frist Combobox (txtKategorie) are fix!
I want the values of the second Combobox (txtTyp) to change according to what the user chooses in the first one.
If the user chooses "Datalogger" the second combobox should only contain "Base Layer Classic" and "Base Layer Plus" as can be seen in the image.
The same idea is true for "Accelerometer".
I've put my code in the AfterUpdate Event of the first Combobox:
If txtKategorie.Value = "Datalogger" And txtTyp.ListCount = 0 Then
i = 1
Do While txtTyp.ListCount < DCount("ID", "tblNomenklatur", "[Kat] = 'K'")
txtTyp.AddItem DLookup("[Typ]", "tblNomenklatur", "[ID] =" & i And "[Kat] = 'K'")
'And "[Kat] = 'K'"
i = i + 1
Loop
When the form opens only the first Combobox "txtKategorie" has Values. When the user chooses Datalogger the code checks how many records in the table have the [Kat] = "K" to define how long the Do While-Statement will run. Then the "txtTyp.AddItem"-Statement should add "Base Layer Classic" and "Base Layer Plus" to the "txtTyp" Combobox. But unfortunately the Code doenst work. There is a problem with the Dlookup-Statement containing tow criterias. If i remove either one of the two criterias the Code works but delivers wrong results for the second Combobox obviously. If i leave it like this the second Combobox stays empty.
Does someone know what im doing wrong?
You can do it easily by below code. Change table name with your table name.
Private Sub txtKategorie_AfterUpdate()
Me.txtTyp.RowSource = "SELECT DISTINCT Table1.Typ FROM Table1 WHERE Table1.Kategorie='" & Me.txtKategorie & "'"
Me.txtTyp.Requery
End Sub
Or you can do it graphically from row source query builder. Below are steps.
Combobox txtKategorie is fix. Fine!
For second combobox txtTyp follow the below steps.
Select combobox txtTyp. From property windows select Row Source then click on query builder ... small three dot. See screenshot.
In query builder window build a query from your data table like screenshot and set criteria for Kategorie column is [Forms]![Form1]![txtKategorie] Save and close the query bulder window.
Now for Combobox txtKategorie in After Update event write below line to requery txtTyp. You are done!
Private Sub txtKategorie_AfterUpdate()
Me.txtTyp.Requery
End Sub
I got a Database, where I apply to a name a Main and Subgroup.
When I enter a MainGroup f.e. Granades, just subgroup elements like "attack-granades" etc. should be shown.
In genereal it works by writing in this into the MainGroup-Combobox at my Form.
Private Sub MunHauptgruppeRef_AfterUpdate()
Me.MunUntergruppeRef.Requery
Me.MunUntergruppeRef.RowSource = " SELECT UnterGrpNR, UnterGrpName FROM tbl_UnterGruppen WHERE UnterHauptGruppenNr = " & MunHauptgruppeRef.Value & " ORDER BY UnterGrpName ASC"
The Problem is, if I load the datas in my form again, it just shows the related Number to the "Sub-Combobox data" 1( f.e. 35 for Attack-Grenade ) , but not the Name itself. After I reselect the entry in my Main-Combobox(Grenade), it shows the right sub-data which was saved. 2
Tried Requery on Form_Load or Requery of the Combo-Boxes itself. nothing helped so far.
Made some Video3
You need to add the code from Private Sub MunHauptgruppeRef_AfterUpdate() to your Form_Current event, this will refresh your combo box row source to the current value of your MunHauptgruppeRef combobox as you cycle through your records. Also you need to call the Me.MunUntergruppeRef.Requery after you've set the Me.MunUntergruppeRef.RowSource.
You can also add a check when your in a New Record, for the code not to run on the Current Event. See here https://learn.microsoft.com/en-us/office/vba/api/access.form.newrecord
I'm using an Access 2003 database and have 2 comboboxes I am trying to work with. The first box I have perfected already, which is a dropdown of different tables (categories of parts). Once that table is selected, I want to be able to look at the part numbers within that category through a dropdown box selection. From here I want to be able to pull up the correct report for that category with that part number in it so I can print a report for every part number. I'm sure I'll have to write some sort of VBA, Query or Macro AfterUpdate() code, but I just don't know how to fill that second combobox with the selected table's part numbers.
Click here for an image of my Menu layout
Here's my Query for the first box to show the tables I want:
SELECT Msysobjects.Name
FROM Msysobjects
WHERE (((Msysobjects.Name) not Like "MSYS*"
And (Msysobjects.Name) not like "_*"
And (Msysobjects.Name) not like "~*"
) AND ((Msysobjects.Type)=1))
ORDER BY Msysobjects.Name;
And I think this is what I'll need to print after the second box has it's selection:
Private Sub partnumberselect_AfterUpdate()
DoCmd.OpenTable Forms![_Datasheet Printing].Form.TagLabelSelection.Column(1), acViewNormal
End Sub
Thank you in advance and let me know if you have any questions.
You are attempting what are called "cascading comboboxes" which means the second box is dependent on the selection of the first.
This is accomplished through the control source of the second combo box.
The first thing you should do is write a query that returns all possible options of the second combobox, without caring so much about filtering it based on the first combo selection. Once you have it returning the correct data, you will add a WHERE clause to the second box's control source that's something like:
WHERE Msysobjects.Name Like Forms![_Datasheet Printing]!TagLabelSelection.Value
This is referencing your first combobox on your form. So after a selection is made in the first combobox, the underlying control source of the second will have the proper criteria to return the appropriate options.
However, you will need to add some VBA to the AfterUpdate() event on the first combobox. Once the selection is made, you need the second box to refresh the control source to populate the correct selections. The code is simply:
Forms![_Datasheet Printing]![MySecondComboboxName].Requery
Please see the example below.
Private Sub cboCountry_AfterUpdate()
On Error Resume Next
cboCity.RowSource = "Select tblAll.City " & _
"FROM tblAll " & _
"WHERE tblAll.Country = '" & cboCountry.Value & "' " & _
"ORDER BY tblAll.City;"
End Sub

I've built an unbound form which allows a user to select from two combo boxes that contain related information (Zone and Watershed Unit -- each Zone contains multiple watershed units) in order to see what regulations apply to each. Based on these selections (stored in txtZone and txtWU on the main form) a subform would show the existing regulations (sfrmRegsbyZWU based on qryRegsbyZWU). This serves as a reference for the user, who picks a new regulation to add from another subform, clicks a button, and the selection is added to the regulations for the Zone/Watershed Unit selected. I had this successfully built with a workaround in the OnCurrent event of the subform (which was undesirable because the user couldn't click on a record and delete it) and everything worked until I added inserted code to change the query definitions for the query which is the basis for the subform as opposed to having it in the "On current" event of the subform.
At that point the requery syntax in the main form which had previously worked stopped working. This is in all embedded in a navigation form in Access 2010, so the previously working syntax was:
Forms!frmNav!NavigationSubform.Form.sfrmRegsbyZWU.Requery
I've tried every permutation of Requery I can think of, and I can not get it working. The underlying query has been changed, but the form doesn't update to reflect it. Can anyone explain to me what has gone wrong, and how to fix it? The code (attached to the _After Update() event of the combo boxes) is:
Private Sub cboZone_AfterUpdate()
'Changes WU combo box as well as the underlying text boxes
Me.cboWU.SetFocus
Me.cboWU = ""
'Blank out other selections
Me.txtWU.SetFocus
Me.txtWU = ""
'Update text box with combobox selection
Me.txtZone.SetFocus
Me.txtZone = Me!cboZone.Column(0)
'Change the query underlying the Existing Regs panel (frmRegsbyZWU, qryRegsbyZWU) to reflect selection
Dim strZSQL As String
Set qdfZ = CurrentDb().QueryDefs("qryRegsbyZWU")
Dim myZVar As Variant
myZVar = Forms!frmNav!NavigationSubform.Form.txtZone
'MsgBox (myZVar)
If IsNull(myZVar) Then
strZSQL = "SELECT * FROM tblRegulations WHERE FALSE"
Else
strZSQL = "SELECT * FROM tblRegulations WHERE Zone_No=" & Forms!frmNav!NavigationSubform.Form.txtZone
End If
'MsgBox (strZSQL)
qdfZ.SQL = strZSQL
'DoCmd.OpenQuery ("qryRegsbyZWU")
Forms!frmNav!NavigationSubform.Form.sfrmRegsbyZWU.Requery
Thanks in advance for any help!
