如何遍历窗体中的所有控件，包括子窗体中的控件 - Access 2007 [英] How to loop through all controls in a form, including controls in a subform - Access 2007

问题描述

正如我的问题标题所暗示的，如何遍历表单中的所有控件，包括子表单.

As the title of my question suggest, how is it possible to loop through all the controls in a form, including subforms.

例如我使用下面的子程序来设置带有标签*的控件的背景颜色

For example I use the below sub routine to set the background colour of controls with the tag *

Public Sub colCtrlReq(frm As Form)
'  Sets background color for required field -> Tag = *
Dim setColour As String
setColour = RGB(255, 244, 164)
Dim ctl As Control
For Each ctl In frm.Controls
        If ctl.ControlType = acTextBox Or ctl.ControlType = acComboBox Or ctl.ControlType = acListBox Then
            If InStr(1, ctl.Tag, "*") <> 0 Then
                ctl.BackColor = setColour
            End If
        End If
Next ctl
Set ctl = Nothing
End Sub

如何更改它以捕获子窗体中的控件?在此先感谢您的帮助或指点.

How would alter this to catch the controls in a subform? Thanks in advance for any help or pointers.

推荐答案

可以使用递归

Public Sub colCtrlReq(frm As Form)
''  Sets background color for required field -> Tag = *
Dim setColour As String
setColour = RGB(255, 244, 164)
Dim ctl As Control
For Each ctl In frm
        If ctl.ControlType = acTextBox Or ctl.ControlType = acComboBox _
            Or ctl.ControlType = acListBox Then
            If InStr(1, ctl.Tag, "*") <> 0 Then
                ctl.BackColor = setColour
            End If
        ElseIf ctl.ControlType = acSubform Then
            colCtrlReq frm(ctl.Name).Form

        End If
Next ctl
Set ctl = Nothing
End Sub
