在Excel中，我已经创建了一个输入数据的用户窗体，用于在工作记录工作表中添加新数据记录。最近，老板提出了新的需求，要通过该用户窗体能够编辑数据记录，增强其功能。

这是我们在使用Excel编程时经常会遇到的问题。虽说直接在工作表中添加数据没有什么不好的，但就是有很多人喜欢使用自已设计的界面输入数据，包括我自已。在设计好输入数据界面后，更进一步增强界面的功能，可以查找数据，对找到的数据进行编辑并将修改更新到工作表中。如下所示。

用户窗体界面设计

存储数据的工作表如下所示。

根据工作表数据结构，设计用户窗体如下所示。

其中，用于导航的4个标签按钮放置在一个名为fraNavigate的框架控件中。

编写代码

通用代码

在标准模块中，输入下面的代码：

‘ API声明

#If VBA7 And Win64 Then

Public Declare PtrSafe Sub Sleep Lib”kernel32″ (ByVal dwMilliseconds As LongPtr)

#Else

Public Declare Sub Sleep Lib”kernel32″ (ByVal dwMilliseconds As Long)

#End If

‘ 常量声明

Public Const MOUSE_DOWN_SLEEP =25

‘ 全局变量声明

Public blnFormComplete AsBoolean

Public blnMouseDown As Boolean

Public strNotCompleted AsString

‘ 代表消息框信息的变量声明

Public intResponse As Integer

Public lngStyle As Long

Public strInput As String

Public strMsg As String

Public strTitle As String

‘与工作表行数相关的变量声明

Public lngLastRow As Long

Public lngRow As Long

Public lngMatchRow As Long

‘获取工作表中最后的数据行

With objWorkSheetFindLastRow

LastRow = .Cells(.Rows.Count, _

intColFindLastRow).End(xlUp).Row

代码太长，但很简洁明了，可以作为一个模板，稍作修改即可用于其它输入、查找和编辑的情形。如果你有类似的需求或者想要进一步研究，可以下载示例工作簿。
