如何在另一个Excel实例中连接到OPEN工作簿
目前，我可以在1台PC上的2个独立的Excel实例内同时运行2个Excel VBA进程。
我的目标是每分钟将Excel实例2中的数据导入到Excel实例1中。
不幸的是，无法从Excel实例1中的工作簿连接到Excel实例2中的打开工作簿。
由于我可以连接到已保存的工作簿，因此解决scheme可能是每隔一分钟在实例2中保存工作簿，并从已保存的工作簿中检索新数据。
虽然这是一个相当沉重的方法。 有没有更好的解决scheme来连接到Excel的另一个实例中的另一个打开的工作簿？
（在同一个实例中打开工作簿是没有办法的，因为在这种情况下，我不能再同时运行2个VBA进程。）
谢谢！

Option Explicit Public Sub GetDataFromExternalXLInstance() Dim instanceFile As Object, ur As Variant, lr As Long 'if not already open, GetObject() will open it in a new instance Set instanceFile = GetObject("C:\Tmp\TestData2.xlsx") '(code running from TestData1) ur = instanceFile.Worksheets(2).UsedRange 'get used range from 2nd Worksheet With ActiveSheet lr = .Cells(.Rows.Count, "A").End(xlUp).Row + 1 'last row on active sheet .Range(.Cells(lr, "A"), .Cells(UBound(ur) + lr - 1, UBound(ur, 2))) = ur End With 'instanceFile.Close 'Set instanceFile = Nothing End Sub 使用API调用的长版本（来自GetObject() Excel帮助文件）

不确定你的意思与两个Excel VBA进程同时进行，但如果您有一个工作簿在Excel的第二个实例中打开，您可以访问GetObject
Sub ConnectToWB() Const FILENAME = "Fulle File Name" Dim wb As Workbook Dim wks As Worksheet Set wb = GetObject(FILENAME) Set wks = wb.Worksheets(1) Debug.Print wks.Cells(1, 1) End Sub
