我如何通过使用Excel VB在文本框来自两个或多个用户窗体的文本框中输入数据来将数据输入到excel中？

如果您声明要公开阅读的每个文本字段，则可以这样进行：

 Class MainForm
    Form firstPage
    Form secondPage
    ...

    Private Sub cmdAddData_Click()
     'Copy input values to sheet.
    Dim lRow As Long
    Dim ws As Worksheet
    Set ws = Worksheets("Summary")
    lRow = ws.Cells(Rows.Count, 1).End(xlUp).Offset(1, 0).Row
    With ws
        .Cells(lRow, 1).Value = firstPage.txtNo.Value
        .Cells(lRow, 2).Value = firstPage.txtKode.Value
        .Cells(lRow, 3).Value = firstPage.txtNamaPerusahaan.Value
        .Cells(lRow, 4).Value = firstPage.txtSector.Value
        .Cells(lRow, 5).Value = firstPage.txtTime.Value
        'UserForm2Begin'
        .Cells(lRow, 7).Value = secondPage.txtKas.Value
        .Cells(lRow, 8).Value = secondPage.txtInvestasi.Value
        .Cells(lRow, 9).Value = secondPage.txtDanaTerbatas.Value
        .Cells(lRow, 10).Value = secondPage.txtPiutangUsaha.Value
        'UserForm2End'
      End With

    'Clear input controls.
    Me.txtNo.Value = ""
    Me.txtKode.Value = ""
    Me.txtNamaPerusahaan.Value = ""

    firstPage.txtSector.Value = ""
    firstPage.txtTime.Value = ""
    'Userform2Begin'
    secondPage.txtKas.Value = ""
    secondPage.txtInvestasi.Value = ""
    secondPage.txtDanaTerbatas.Value = ""
    secondPage.txtPiutangUsaha.Value = ""

End Sub



End Class

如前所述，如果要使用此方法，则需要将可见性设置为public（在图形编辑器中，其attribute为Modifiers）

更好的解决方案是在Mainfrom中声明一个对象，该对象具有以后要在Excel文件中拥有的所有值的属性。然后将此对象赋予每种形式，例如在构造函数中，然后填充它。然后，在Mainform中，您可以读取对象的所有属性并将其写入文件。用于保存数据的对象可能是这样的：

    Class DataObject
        Public txtNo as String
        Public txtKode as String
        ...
    End Class

您在用户可以看到的第一个表单中声明它，然后将其提供给随后的每个表单

Class FirstForm
   Dim data as DataObject
   ...

   private sub openNextWindow()
       dim sec as SecondForm= new SecondForm(DataObject)
       ...
   end sub
end class

直到您最终在cmdAddData处执行以下操作：

Private Sub cmdAddData_Click()
     'Copy input values to sheet.
    Dim lRow As Long
    Dim ws As Worksheet
    Set ws = Worksheets("Summary")
    lRow = ws.Cells(Rows.Count, 1).End(xlUp).Offset(1, 0).Row
    With ws
        .Cells(lRow, 1).Value = data.txtNo
        .Cells(lRow, 2).Value = data.txtKode
        ...      
End Sub
