Microsoft Access - Loop through all forms and controls on each form - forms

Question

Okay so when I press a specific button I want to loop through all forms, then find every control in each form with the tag 'TESTING'. If the tag = 'TESTING' then I want to change the caption of the object to 'abc123'.
The only objects with the tag 'TESTING' will be labels, so they will have the caption property.
So far I have this as the function:
Public Function changelabel()
On Error Resume Next
Dim obj As AccessObject, dbs As Object
Dim ctrl as Control
Set dbs = Application.CurrentProject
For Each obj In dbs.AllForms
DoCmd.OpenForm obj.Name, acDesign
For Each ctrl In Me.Controls
If ctrl.Tag = "TESTING" Then
ctrl.Caption = "abc123"
End If
Next ctrl
Next obj
End Function
Then this as the button code:
Public Sub TestButton_Click()
Call changelabel
End Sub
So it executes the first for loop and opens all the forms in design view correctly. The problem lies with the second for loop. None of the label captions that have the tag property as 'TESTING' are changed to 'abc123'.
So what do I need to change to get the second for loop to work?

Answer 1

Public Sub GetForms()
Dim oForm As Form
Dim nItem As Long
Dim bIsLoaded As Boolean
For nItem = 0 To CurrentProject.AllForms.Count - 1
bIsLoaded = CurrentProject.AllForms(nItem).IsLoaded
If Not bIsLoaded Then
On Error Resume Next
DoCmd.OpenForm CurrentProject.AllForms(nItem).NAME, acDesign
End If
Set oForm = Forms(CurrentProject.AllForms(nItem).NAME)
GetControls oForm
If Not bIsLoaded Then
On Error Resume Next
DoCmd.Close acForm, oForm.NAME
End If
Next
End Sub
Sub GetControls(ByVal oForm As Form)
Dim oCtrl As Control
Dim cCtrlType, cCtrlCaption As String
For Each oCtrl In oForm.Controls
If oCtrl.ControlType = acSubform Then Call GetControls(oCtrl.Form)
Select Case oCtrl.ControlType
Case acLabel: cCtrlType = "label": cCtrlCaption = oCtrl.Caption
Case acCommandButton: cCtrlType = "button": cCtrlCaption = oCtrl.Caption
Case acTextBox: cCtrlType = "textbox": cCtrlCaption = oCtrl.Properties("DataSheetCaption")
Case Else: cCtrlType = ""
End Select
If cCtrlType <> "" Then
Debug.Print oForm.NAME
Debug.Print oCtrl.NAME
Debug.Print cCtrlType
Debug.Print cCtrlCaption
End If
Next
End Sub

Something like this
Public Function changelabel()
Dim f As Form
Dim i As Integer
Dim c As Control
For i = 0 To CurrentProject.AllForms.Count - 1
If Not CurrentProject.AllForms(i).IsLoaded Then
DoCmd.OpenForm CurrentProject.AllForms(i).Name, acDesign
End If
Set f = Forms(i)
For Each c In f.Controls
If c.Tag = "TESTING" Then
c.Caption = "TESTING"
End If
Next c
Next i
End Function
You'll need to add a bit of house-keeping to set the objects used to nothing etc..
