Excel VBA Forms - форматирование чисел и изменение события

0 голосов
/ 30 июня 2019

2 части вопроса: я построил форму для отображения большого ряда информации в более приемлемом формате. Во-первых, событие OnChange, которое я нашел здесь: https://stackoverflow.com/a/5942200/2317071, раньше работало, но оно перестало работать, когда я немного выделил свой код. Во-вторых, действительно ли мне нужно вручную форматировать текстовое поле в соответствии с форматом ячейки каждый раз? У меня проблемы с преобразованием чисел обратно; например 13,5% устанавливаются на 0,135 (достаточно справедливо), но не для ячейки и текстового поля.

Надеюсь, мой код достаточно прокомментирован, чтобы его можно было прочитать, но по сути я создаю форму, которую можно использовать на одном из нескольких листов, чтобы отобразить всю активную строку данных в форме. Каждый лист кандидата имеет значение ИСТИНА или ЛОЖЬ в каждой ячейке в строке 1. Если столбец имеет значение ИСТИНА, это поле включается в форму, в противном случае я перехожу к следующему полю, которое пользователь хочет отобразить. Если ячейка в активной строке является формулой, пользователь не может редактировать текстовое поле. Если пользователь изменяет одно из значений, я хочу определить это и дать возможность сохранить, а затем записать новое значение обратно в активную строку в соответствующей ячейке.

Что мне здесь не хватает? Спасибо за вашу помощь!

С https://stackoverflow.com/a/5942200/2317071: Модуль класса "clsTextBox", содержит: 

Private WithEvents MyTextBox As MSForms.TextBox

Public Property Set Control(tb As MSForms.TextBox)
    Set MyTextBox = tb
End Property

Private Sub MyTextBox_Change()
    FormDataChanged = True
End Sub

Module_FormCalls содержит код, который вызывает каждая кнопка, в основном просто устанавливает BaseSheet, а затем вызывает форму: 


Public BaseSheet As Worksheet
Public FormDataChanged As Boolean

Sub CallForm_4B2()
    Dim ThisSheet As Worksheet
    Set ThisSheet = Worksheets("4B2")
    Debug.Print ThisSheet.Name
    Set BaseSheet = ThisSheet
    Debug.Print BaseSheet.Name
    frmRecordDisplay.Show
    Set ThisSheet = Nothing
End Sub

Sub CallForm_4B1()
    Dim ThisSheet As Worksheet
    Set ThisSheet = Worksheets("4B1")
    Debug.Print ThisSheet.Name
    Set BaseSheet = ThisSheet
    Debug.Print BaseSheet.Name
    frmRecordDisplay.Show
    Set ThisSheet = Nothing
End Sub

frmRecordDisplay имеет рабочий код: 


Option Explicit
Dim ColumnUsed(1 To 80) As Integer
Dim DataChangedString As String

Private Sub CommandButtonNext_Click()

    Dim Message As String
    Dim SaveChoice

    If DataChanged() Then 'Custom function shown below to detect differences between what is in each field now and what was originally put in them
