清除包含數據的單元格

Question

我正在使用以下方法將信息從電子郵件導出到電子表格中：

Sub CopyToExcel()
Dim xlApp As Object
Dim xlWB As Object
Dim xlSheet As Object
Dim olItem As Outlook.MailItem
Dim vText As Variant
Dim sText As String
Dim vItem As Variant
Dim i As Long
Dim rCount As Long
Dim bXStarted As Boolean
Const strPath As String = "C:\Users\username\Desktop\Spreadsheet.xlsx" 'the path of the workbook

If Application.ActiveExplorer.Selection.Count = 0 Then
    MsgBox "No Items selected!", vbCritical, "Error"
    Exit Sub
End If
On Error Resume Next
Set xlApp = GetObject(, "Excel.Application")
If Err <> 0 Then
    Application.StatusBar = "Please wait while Excel source is opened ... "
    Set xlApp = CreateObject("Excel.Application")
    bXStarted = True
End If
On Error GoTo 0
'Open the workbook to input the data
Set xlWB = xlApp.Workbooks.Open(strPath)
Set xlSheet = xlWB.Sheets("Sheet1")

'Process each selected record
 rCount = xlSheet.UsedRange.Rows.Count
  For Each olItem In Application.ActiveExplorer.Selection
    sText = olItem.Body
    vText = Split(sText, Chr(13))
    'Find the next empty line of the worksheet
     rCount = rCount + 1

    'Check each line of text in the message body
    For i = UBound(vText) To 0 Step -1

        If InStr(1, vText(i), "Cell0:") > 0 Then
            vItem = Split(vText(i), Chr(58))
            xlSheet.Range("B" & rCount) = Trim(vItem(1))
            Else
            ActiveCell = Null
        End If

        If InStr(1, vText(i), "Field1:") > 0 Then
            vItem = Split(vText(i), Chr(58))
            xlSheet.Range("D" & rCount) = Trim(vItem(1))
        End If

        If InStr(1, vText(i), "Field2:") > 0 Then
            vItem = Split(vText(i), Chr(58))
            xlSheet.Range("E" & rCount) = Trim(vItem(1))
        End If

        If InStr(1, vText(i), "Field3:") > 0 Then
            vItem = Split(vText(i), Chr(58))
            xlSheet.Range("F" & rCount) = Trim(vItem(1))
        End If

        If InStr(1, vText(i), "Field4:") > 0 Then
            vItem = Split(vText(i), Chr(58))
            xlSheet.Range("H" & rCount) = Trim(vItem(1))
        End If

        If InStr(1, vText(i), "Field5:") > 0 Then
            vItem = Split(vText(i), Chr(58))
            xlSheet.Range("I" & rCount) = Trim(vItem(1))
        End If

        If InStr(1, vText(i), "Field6:") > 0 Then
            vItem = Split(vText(i), Chr(58))
            xlSheet.Range("J" & rCount) = Trim(vItem(1))
        End If


    Next i
    xlWB.Save
Next olItem


Set xlApp = Nothing
Set xlWB = Nothing
Set xlSheet = Nothing
Set olItem = Nothing
End Sub

問題是，如果此命令在不包含特定字段數據的電子郵件上運行，則會保留前一封電子郵件的數據。 我想讓宏清除包含信息的單元格，或者如果在字段中未找到任何內容，則僅在單元格中輸入null。

我知道它一定是ActiveCell.clear或ActiveCell = Null但是我不確定在If語句中的位置。

我試過了，但是不起作用：

If InStr(1, vText(i), "Activity Number:") > 0 Then
            vItem = Split(vText(i), Chr(58))
            xlSheet.Range("B" & rCount) = Trim(vItem(1))
            ElseIf InStr(1, vText(i), "Activity Number:") = 0 Then
            xlSheet.Range("B" & rCount) = Null
        End If

Answer 1

您可以編寫一個函數，將其清除后返回范圍對象。

Function ClearMyRange(r as Range) as Excel.Range
    r.ClearContents
    set ClearMyRange = r
End Function

然后叫它

ClearMyRange(xlSheet.Range("D" & rCount)) = Trim(vItem(1))

我建議使用此函數的原因是，您不必像這樣調用它

ClearMyRange(xlSheet.Range("D" & rCount))
xlSheet.Range("D" & rCount) = Trim(vItem(1))
