Question

我有一份excel表格，用于员工数据录入工作。 excel表包含员工的详细信息。我希望表单通过上一个和下一个按钮浏览每个记录，同时在表单中显示内容。

我已经为此编写了代码，但它无法正常工作。它有时会在到达记录的开头和结尾时提供无效的记录详细信息。帮帮我

Private Sub UserForm_Initialize()
frmEmpDetails.ComboGender.AddItem "Male", 0
frmEmpDetails.ComboGender.AddItem "Female", 1
counter = ActiveSheet.UsedRange.Rows.Count
temp_counter = counter
lblTmpCount.Caption = temp_counter
End Sub

Private Sub btnNext_Click()
status = 1
lblTmpCount.Caption = temp_counter
If (temp_counter >= counter) Then
    MsgBox "Reached end"
Else
    temp_counter = temp_counter + 1
    txtID.Text = Cells(temp_counter, 1).Value
    txtName.Text = Cells(temp_counter, 2).Value
    txtDOB.Text = Cells(temp_counter, 3).Value
    ComboGender.Value = Cells(temp_counter, 4).Value
    txtAboutEmp.Text = Cells(temp_counter, 5).Value
    lblTmpCount.Caption = temp_counter
End If
End Sub

Private Sub btnPrev_Click()
status = 1
lblTmpCount.Caption = temp_counter
If (temp_counter < 2) Then
    MsgBox "Reached beginning"
Else
    txtID.Text = Cells(temp_counter, 1).Value
    txtName.Text = Cells(temp_counter, 2).Value
    txtDOB.Text = Cells(temp_counter, 3).Value
    ComboGender.Value = Cells(temp_counter, 4).Value
    txtAboutEmp.Text = Cells(temp_counter, 5).Value
temp_counter = temp_counter - 1
End If
End Sub

一旦控件到达文件的结尾/开头，您就可以禁用相应的按钮。

我建议您使用子程序来获取和放置数据，然后使用导航按钮更改行。测试你的GetData和PutData例程，以确保它们完成对它们的期望。

以下是我的一个项目中使用类似控件和文本框和单元格引用的示例。在我的例子中，我在第4行开始了数据。大多数变量是在激活表单时声明的。

Private Sub cmdFirst_Click()   
    R = 4
    Call GetData         
End Sub

Private Sub cmdPrev_Click()
    If R = 4 Then
        MsgBox ("Already on First Record")
    Else
        R = R - 1
        Call GetData        
    End If            
End Sub

Private Sub cmdNext_Click()
    lastRow = Sheets("Sheet1").Range("A" & Rows.Count).End(xlUp).row   
    If R = lastRow Then
        MsgBox ("Already on the last record.")
    Else
        R = R + 1
        Call GetData        
    End If   
End Sub

Private Sub cmdLast_Click()
    R = Sheets("Sheet1").Range("A" & Rows.Count).End(xlUp).row
    Call GetData
End Sub

Private Sub cmdNew_Click()
    R = (Sheets("Sheet1").Range("A" & Rows.Count).End(xlUp).row) + 1
    Call SetID
    Call ClearData
    txtID = newID
End Sub

Private Function SetID()  
Dim rng As Range
    Set rng = Sheets("Sheet1").Range("a4", Sheets("Sheet1").Range("A" & Rows.Count).End(xlUp).row

    newID = Application.WorksheetFunction.Max(rng) + 1

End Function

Private Sub GetData()
    txtID.Text = Sheets("Sheet1").Cells(R, 1).Value
    txtName.Text = Sheets("Sheet1").Cells(R, 2).Value
    txtDOB.Text = Sheets("Sheet1").Cells(R, 3).Value
    ComboGender.Value = Sheets("Sheet1").Cells(R, 4).Value
    txtAboutEmp.Text = Sheets("Sheet1").Cells(R, 5).Value
End Sub

Private Sub ClearData()
    txtName.Text = ""
    txtDOB.Text = ""
    ComboGender.Value = ""
    txtAboutEmp.Text = ""
End Sub

Private Sub PutData()
    Sheets("Sheet1").Cells(R, 1).Value = txtID.Text
    Sheets("Sheet1").Cells(R, 2).Value = txtName.Text
    Sheets("Sheet1").Cells(R, 3).Value = txtDOB.Text 
    Sheets("Sheet1").Cells(R, 4).Value = ComboGender.Value
    Sheets("Sheet1").Cells(R, 5).Value = txtAboutEmp.Text
End Sub

使用上一个和下一个按钮的行导航excel形成vba
