演示 GetObject 和 CreateObject

MSDN-GetObject 函式

返回對 ActiveX 元件提供的物件的引用。

當存在物件的當前例項時，或者如果要建立已載入檔案的物件，請使用 GetObject 函式。如果沒有當前例項，並且你不希望以載入檔案的方式啟動物件，請使用 CreateObject 函式。

    Dim ThisXLApp As Excel.Application 'An example of early binding
    Dim AnotherXLApp As Object 'An example of late binding
    Dim ThisNewWB As Workbook
    Dim AnotherNewWB As Workbook
    Dim wb As Workbook
    
    'Get this instance of Excel
    Set ThisXLApp = GetObject(ThisWorkbook.Name).Application
    'Create another instance of Excel
    Set AnotherXLApp = CreateObject("Excel.Application")
    'Make the 2nd instance visible
    AnotherXLApp.Visible = True
    'Add a workbook to the 2nd instance
    Set AnotherNewWB = AnotherXLApp.Workbooks.Add
    'Add a sheet to the 2nd instance
    AnotherNewWB.Sheets.Add
    
    'You should now have 2 instances of Excel open
    'The 1st instance has 1 workbook: Book1
    'The 2nd instance has 1 workbook: Book2

    Set ThisNewWB = ThisXLApp.Workbooks.Add
    'Now loop through the workbooks and show their names
    For Each wb In ThisXLApp.Workbooks
        Debug.Print wb.Name
    Next
    'Now the 1st instance has 2 workbooks: Book1 and Book3
    'If you close the first instance of Excel,
    'Book1 and Book3 will close, but book2 will still be open
