VBA 脚本卡在 Workbook.Close 处

Question

我正在尝试在 Visual Basic for Applications 中编写一个 hello world 应用程序，即修改 Excel 工作表中的单元格。这是:

Sub hello()

    Dim obj As Object
    Dim Workbook As Object

    Set obj = CreateObject("Excel.Application")
    Set Workbook = obj.Workbooks.Open("C:\Users\gbuday\Desktop\Oktatás\Excel\start.xlsx")

    Workbook.Worksheets("Munka1").Range("B3") = "Hello World!"

    Workbook.Close
    Set Workbook = Nothing
    Set obj = Nothing

End Sub

运行时，Excel挂起，我无法停止脚本运行，只能杀死excel进程。调试它时，它卡在 Workbook.Close 行。该行有什么问题？

问题是您没有给 Excel 足够的时间来完成其操作。通常 DoEvents 可以解决问题。另外为了避免混淆，您可能需要将变量命名为“wbk”而不是“Workbook”

Sub hello()
    Dim obj As Object, wbk As Object

    Set obj = CreateObject("Excel.Application")
    Set wbk = obj.Workbooks.Open("C:\Users\gbuday\Desktop\Oktatás\Excel\start.xlsx")

    wbk.Worksheets("Munka1").Range("B3") = "Hello World!"

    DoEvents

    '~~> Change True to False if you do not want to save
    wbk.Close SaveChanges:=True

    Set wbk = Nothing: Set obj = Nothing
End Sub
