vba脚本挂在Workbook.Close

Question

我试图在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.这里是:

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,它挂起了Workbook.Close线.那条线有什么问题？

问题是你没有给Excel足够的时间来完成它的操作.通常一个DoEvents会解决问题.另外,为避免混淆,您可能希望将变量命名为"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
