帶有 Outlook VBA 的孤立 Excel 進程

Question

我無法結束使用 Outlook VBA 打開的 Excel 進程。

我研究了一些解決方案，例如在最后將變量設置為 Nothing 並在所有變量之后使用 With 語句。

當我一遍又一遍地調用 Excel 時，孤立的進程似乎會導致問題。

該代碼假設下載附件，將一些單元格值復制到工作簿中，保存並關閉文檔。

Answer 1

您可以在此類應用程序中應用一些推薦規則。

1- 在打開 Excel 之前，檢查 Excel 是否已經打開並獲取正在運行的實例。 您可以創建一個自定義例程來做到這一點：

Function getExcelApp() As Excel.Application
    On Error Resume Next
    Set getExcelApp = GetObject(, "Excel.Application")
    If Err.Number <> 0 Then Set getExcelApp = CreateObject("Excel.Application")
End Function

2- 使應用程序可見，至少在您仍在編寫和調試代碼的階段。

Set myXLApp = getExcelApp ' <-- get it or create it
myXLApp .Visible = true ' <-- useful at least in the development phase

3-您最終只需一步即可縮短兩個階段（創建應用程序，打開文檔）

Dim wb as Excel.Workbook
Set wb= GetObject(filepath)

這將獲得一個已經打開的文檔實例，或者如果沒有打開它。 您可以稍后將應用程序對象作為wb.Application 。

4- 確保正確處理錯誤情況，所有路徑都將關閉 Excel 應用程序，包括由錯誤導致的路徑。

5- 由於您使用的應用程序是臨時的，請將其保持為DisplayAlerts = False狀態。 正如我所見，您在退出之前將其重置為DisplayAlerts = true 。 這是頭痛的根源。 想象一下被一些警報消息框阻止的“不可見”應用程序？ 我建議你放棄那條線（保持false ）。

6- 限定范圍和對象變量

Set wbtemp = myXlApp.Workbooks.Open(filepath, 3, True) '<-- better than using the unqualified Workbooks
