I’m newbie in VB and Access. So I have table with Yes/No column „Channged”, and some text column, when I change text in text field (using form) I want to set Changet to true.
In my form, I handle Update event:
Private Sub Question_Updated(Code As Integer)
End Sub
How can I update Changed column through this method? Thanks.
You can use the following code to set your Yes/No UNBOUND field as long as it is included in your recordset for the form. Note that I am using the 'AfterUpdate event for the field you will be changing. The update will take place AFTER you move to another record or close the form.
Private Sub Question_AfterUpdate()
Me!YesNo = vbYes
End Sub

I have set an unbound checkbox in my form to set a date field using Now() if checked, it also Nulls out the associated date field if unchecked, both using the On Click event:
Private Sub DXF_Chk_Click()
Me.dxfLimits = IIf(Me.DXF_Chk, Now(), Null)
End Sub
This works perfectly, however, when I close and re-open the form and check the same record the checkboxes appear empty. I understand why this is happening - the checkbox isn't bound directly to the Date field - but I need to correct it. My thought was to use an On Load or On Current (both?) event to look at the corresponding date field for not null and make the checkboxes appear checked... but I'm not sure which would be the better option, nor what would make that happen.
I tried to reverse the On Click IIF in the Form Current event:
Private Sub Form_Current()
Me.DXF_Chk = IIf(Me.dxflimits, Now(), Null)
End Sub
and got an error.
Not sure what your doing, but a checkbox must be passed a Boolean, so try:
Private Sub Form_Current()
Me!DXF_Chk.Value = Not IsNull(Me!dxflimits.Value)
End Sub
I have been asked to create a field(FORM) in access that get the USERNAME who has logged in . I created the string VBA Me!EmployeeID = Environ("USERNAME") which is on load. However, I noticed when I click on next record it goes way and wont get updated. I am not VBA expert that why I am here. What string should I write and where should I put it?
Should it be on form properties or the Employee ID field properties and also which part Before update or After?
Use form Current event. This event occurs both when a form is opened and whenever the focus leaves one record and moves to another
Private Sub Form_Current()
Me!EmployeeID = Environ("USERNAME")
End Sub
I've a form in MS access that holds a subform showing records from a table. I've got a textbox whichs content is based on the selected record form the subset. If i select a record with id 2 then the value of the textbox is set to 2.
I want to copy the value of the textbox to another textbox of the form each time the value is changed.
The onChange eventhandler on the textbox bound to the subform does not trigger, neither does any other event when i select a record in the subform.
I'd either write some vba code to copy the text or use a makro.
It probably is triggering if you change the field manually, e.g., this code works for me:
Private Sub Text0_Change()
Text2.Value = Text0.Text
End Sub
(note value and text, as what you see in the field while you are editing it is not that same as the value of the field)
but not if you update it through VBA
Setting the value of a control by using a macro or Visual Basic doesn't trigger this event for the control. You must type the data directly into the control, or set the control's Text property.

If the fields were named like in my example, I'd have whatever VB that updates Text0 also update Text2
I am trying to create a method that displays a selected table in a DS view form. The form will be used repeatedly to view different tables, so I figured the easiest way would be to create a form and dynamically change the RecordSource based on the user selection.
I created a form called "frmDisplay" to be used to display the contents of a table to the users. I am trying to use this code to update the form.
Private Sub btnViewEntries_Click()
Dim frmDisplay As Form
Dim selection As String
Me.cmboSelection.SetFocus
selection = "tbl" & Me.cmboSelection.Text
Set frmDisplay.RecordSource = selection
DoCmd.OpenForm "frmDisplay", acFormDS
End Sub
Currently, the code is throwing an "Improper use of property" error when I try to set the RecordSource to the selection made in the combo box.
Set frmDisplay.RecordSource = selection
I have looked around for a while now, but I cannot seem to find any definitive answer that applies to this example. Most posts that I found were missing the Set keyword...
Does anyone recognize the problem? More importantly, is this even the best way to make this
work?
Thanks
_____ EDIT _____
I figured it out, see code below.
Dim selection As String
Me.cmboSelection.SetFocus
selection = "SELECT * from tbl" & Me.cmboSelection.Text
DoCmd.OpenForm "frmDisplay", acDesign
Forms!frmDisplay.Form.RecordSource = selection
DoCmd.Close acForm, "frmDisplay", acSaveYes
DoCmd.OpenForm "frmDisplay", acFormDS
I note you've already provided your answer, but you may find the following helpful.
If you have a main form with the controls cmboSelection and btnViewEntries then add a subform control and call it fsbDisplay. Don't put anything in this subform, leave it unbound.
Now try the following one-liner:
Private Sub btnViewEntries_Click()
fsbDisplay.SourceObject = "Table.tbl" & cmboSelection.Value
End Sub
The advantage of this method is that you can use it to call up any table or query (prefix with Query. instead of Table.) and the fields shown are dynamically created.
I have a set of ComboBox's in an MS Access 2003 DB that are all bound to fields in a single table. However, the data that they allow you to select doesn't come from that table and instead comes from various other tables. This works fine for the record creation story but now I want to be able to edit the record retroactively. The problem is that I can't figure out how to refill the form elements without writing a bunch of custom code.
My initial inclination is to provide a combo box that limits your choices to record IDs and then do a custom query and use that to set the selected values in all of different form elements. However, I feel like I should be able to do something as simple as DoCmd.GoToRecord , , , ID and the form should repopulate just fine. I'm not opposed to doing the busy work but I'm sure I'm just missing something in my relatively puny knowledge of VBA and Access.
Just to add to the mix, I would offer two approaches, one recommended, the other not.
Approach 1: If you've bound your form to the whole data table (this is the non-recommended approach), you can use the combo box wizard to navigate to the requested record, but I wouldn't recommend it in recent versions of Access:
a. it doesn't allow you to properly name the combo box before it creates code.
b. the code is just WRONG.
Here's the code I just produced in my test database:
Dim rs As Object
Set rs = Me.Recordset.Clone
rs.FindFirst "[InventoryID] = " & Str(Nz(Me![Combo2], 0))
If Not rs.EOF Then Me.Bookmark = rs.Bookmark
This is wrong in so many ways it's just remarkable. This is what the code should be:
With Me.RecordsetClone
.FindFirst "[ID]=" & Me!cmbMyComboBox
If Not .NoMatch Then
If Me.Dirty Then Me.Dirty = False
Me.Bookmark = .Bookmark
Else
MsgBox "Not Found!"
End If
End With
There is no need to clone the form's recordset when the RecordsetClone already exists.
There is no reason to use an object variable when you can just directly use the pre-existing object.
There needs to be a check for a dirty record before departing the record because if you don't force the save, errors in the save process can lead to lost data.
But the better approach is this:
Approach 2: Use the combo box to change the form's underlying recordsource.
The AfterUpdate event of your combo box would look something like this:
If Not IsNull(Me!cmbMyComboBox) Then
Me.Recordsource = Me.Recordsource & " WHERE [ID]=" & Me!cmbMyComboBox
End If
Now, this only works the first time, as on the second resetting of the Recordsource, you end up with two WHERE clauses, which is not good. There are two approaches:
a. assuming that the form opens without a WHERE clause, store the opening recordsource value in a module-level variable in the form's OnLoad event:
Private Sub Form_Load()
strRecordsource = Left(Me.Recordsource,Len(Me.Recordsource)-1)
End Sub
And at the module level, define strRecordsource accordingly:
Dim strRecordsource As String
Then in the combo box's AfterUpdate event, you have this instead:
Me.Recordsource = strRecordsource & " WHERE [ID]=" & Me!cmbMyComboBox
Now, if your form opens with a WHERE clause already defined, it gets more complicated, but I'll not go into that and leave it as an exercise to the reader what the best approach might be.
I presume that you've already set up the row sources for each combo box. So long as you haven't limited the combo box to that list; it should display what you have stored in that column.
However, if your Combo Box changes its list for each row you can do something like this in the record's OnCurrent event or the field's GotFocus event:
Me.combo_box_name.Requery
After re-reading your question, I think I see what you are trying to achieve. You're on the right track with GotoRecord, although I would probably use OpenForm in this case, because it has a WhereCondition property that allows you to use SQL to specify exactly what record to open. It sounds like you want to implement a "jump to record" type functionality in your form, where the user selects a record ID from a list and the form changes to display the selected record.
One possibility is to switch to the new record each time the user selects an item in the ComboBox. You can handle this in the ComboBox's Click event.
I'll use a simple example: suppose you have a Students table, and a StudentForm for viewing/editing records in the Students table. The StudentForm has a ComboBox cboStudentID that is bound to the Students.ID column via it's RowSource property. When you select a student ID in the ComboBox, the StudentsForm will switch to display the corresponding student record.
In the Click event handler for the ComboBox, you can code this "jump to record" functionality with something like the following:
Private Sub cboStudentID_Click()
Dim recordID As Long
'The ItemData property will return the value of the bound'
'column at the specified index.'
recordID = cboStudentID.ItemData(cboStudentID.ListIndex)
'Jump to the record. This assumes we want to use the same form.'
'You can change the form name if you want to open a different form when'
'the user selects an ID from the ComboBox.'
DoCmd.OpenForm "StudentForm", WhereCondition:="Student.ID=" & recordID
End Sub
As David W. Fenton points out in the comments, you can shorten the following line:
recordID = cboStudentID.ItemData(cboStudentID.ListIndex)
to this:
recordID = Me!cboStudentID
or just:
recordID = cboStudentID
since the default value of the ComboBox in this case will be the value of the bound column at the current ListIndex. In this case, you could just remove recordID altogether and code the Click event as follows:
Private Sub cboStudentID_Click()
DoCmd.OpenForm "StudentForm", WhereCondition:="Student.ID=" & cboStudentID
End Sub
