Question

为学校做一个项目，我可以将数据读入我的表单，但我似乎无法从我的表单更新，然后转到新记录。有人可以帮忙。

Private Sub Next_Command_Click()
    Do
        nCurrentRow = nCurrentRow + 1
        TraverseData (nCurrentRow)
    Loop Until NC_C_L.Cells(nCurrentRow, 1).Value = "" Or NC_C_L.Cells(nCurrentRow, 1).Value = Me.***_Text.Value
End Sub

Private Sub Previous_Command_Click()
    Do
        nCurrentRow = nCurrentRow - 1
        TraverseData (nCurrentRow)
    Loop Until nCurrentRow = 1 Or NC_C_L.Cells(nCurrentRow, 1).Value = Me.***_Text.Value
End Sub

Private Sub TraverseData(nRow As Long)
        Me.***_Text.Value = NC_C_L.Cells(nRow, 1)
        Me.***_Box = NC_C_L.Cells(nRow, 2)
        Me.***_Combo.Value = NC_C_L.Cells(nRow, 3)
        Me.***_Combo.Value = NC_C_L.Cells(nRow, 4)
        Me.***_Combo.Value = NC_C_L.Cells(nRow, 5)
        Me.***_Combo.Value = NC_C_L.Cells(nRow, 6)
        Me.***_Combo.Value = NC_C_L.Cells(nRow, 7)
        Me.***_Text.Value = NC_C_L.Cells(nRow, 8)
        Me.***_Text.Value = NC_C_L.Cells(nRow, 9)
        Me.Comments1_Text.Value = NC_C_L.Cells(nRow, 10)
        Me.Comments2_Text.Value = NC_C_L.Cells(nRow, 11)
        Me.Comments3_Text.Value = NC_C_L.Cells(nRow, 12)
        Me.PhoneNumber_Text.Value = NC_C_L.Cells(nRow, 13)
        Me.Address1_Text.Value = NC_C_L.Cells(nRow, 14)
        Me.Address2_Text.Value = NC_C_L.Cells(nRow, 15)
        Me.City_Text.Value = NC_C_L.Cells(nRow, 16)
        Me.State_Combo.Value = NC_C_L.Cells(nRow, 17)
        Me.Zip_Text.Value = NC_C_L.Cells(nRow, 18)
        Me.EMail_Text.Value = NC_C_L.Cells(nRow, 19)
        Me.P_Name_Text.Value = NC_C_L.Cells(nRow, 20)
        Me.P_PhoneNumber_Text.Value = NC_C_L.Cells(nRow, 21)
        Me.P_Address_Text.Value = NC_C_L.Cells(nRow, 22)
    End Sub

（我确实修改了一些名字以反映***。）

通常，您会看到两种不同的方法。

方法1：将范围数据传输到表单控件：

Private Sub TraverseDataToForm(nRow As Long)
        Me.***_Text.Value = NC_C_L.Cells(nRow, 1).Value
        Me.***_Box.Value = NC_C_L.Cells(nRow, 2).Value
End sub

方法2：将控件数据传输到范围：

Private Sub TraverseDataToRange(nRow As Long)
        NC_C_L.Cells(nRow, 1).Value = Me.***_Text.Value 
        NC_C_L.Cells(nRow, 2).Value = Me.***_Box.Value
End sub

SyncValues会将Range链接到MSForms.Control.ControlSource，并在更改记录时更新值。

注意：当用户窗体关闭时，您还必须触发更新值。

Sub SyncValues(ctrl As MSForms.Control, Target As Range)

    If ctrl.ControlSource <> "" Then
        Range(ctrl.ControlSource).Value = ctrl.Value
    End If

    If Not Target Is Nothing Then
        ctrl.ControlSource = Target.Address(True, True, xlA1, True)
    End If
End Sub

Private Sub UserForm_Deactivate()
    TraverseData nCurrentRow
End Sub

Private Sub Next_Command_Click()
    Do
        nCurrentRow = nCurrentRow + 1
        TraverseData nCurrentRow
    Loop Until NC_C_L.Cells(nCurrentRow, 1).Value = "" Or NC_C_L.Cells(nCurrentRow, 1).Value = Me.AAA_Text.Value
End Sub

Private Sub Previous_Command_Click()
    Do
        nCurrentRow = nCurrentRow - 1
        TraverseData nCurrentRow
    Loop Until nCurrentRow = 1 Or NC_C_L.Cells(nCurrentRow, 1).Value = Me.AAA_Text.Value
End Sub

Private Sub TraverseData(nRow As Long)
    If nRow = 0 Then Exit Sub
    SyncValues Me.AAA_Text, NC_C_L.Cells(nRow, 1)
    SyncValues Me.BBB_Box, NC_C_L.Cells(nRow, 2)
    SyncValues Me.CCC_Combo, NC_C_L.Cells(nRow, 3)
    SyncValues Me.DDD_Combo, NC_C_L.Cells(nRow, 4)
    SyncValues Me.EEE_Combo, NC_C_L.Cells(nRow, 5)
    SyncValues Me.FFF_Combo, NC_C_L.Cells(nRow, 6)
    SyncValues Me.GGG_Combo, NC_C_L.Cells(nRow, 7)
    SyncValues Me.HHH_Text, NC_C_L.Cells(nRow, 8)
    SyncValues Me.III_Text, NC_C_L.Cells(nRow, 9)
    SyncValues Me.Comments1_Text, NC_C_L.Cells(nRow, 10)
    SyncValues Me.Comments2_Text, NC_C_L.Cells(nRow, 11)
    SyncValues Me.Comments3_Text, NC_C_L.Cells(nRow, 12)
    SyncValues Me.PhoneNumber_Text, NC_C_L.Cells(nRow, 13)
    SyncValues Me.Address1_Text, NC_C_L.Cells(nRow, 14)
    SyncValues Me.Address2_Text, NC_C_L.Cells(nRow, 15)
    SyncValues Me.City_Text, NC_C_L.Cells(nRow, 16)
    SyncValues Me.State_Combo, NC_C_L.Cells(nRow, 17)
    SyncValues Me.Zip_Text, NC_C_L.Cells(nRow, 18)
    SyncValues Me.EMail_Text, NC_C_L.Cells(nRow, 19)
    SyncValues Me.P_Name_Text, NC_C_L.Cells(nRow, 20)
    SyncValues Me.P_PhoneNumber_Text, NC_C_L.Cells(nRow, 21)
    SyncValues Me.P_Address_Text, NC_C_L.Cells(nRow, 22)
End Sub
