GetObject and Excel - working with VB 5

P: n/a
I found the following under the GetObject help notes and in the
example for GetObject:

"This example uses the GetObject function to get a reference to a
specific Microsoft Excel worksheet (MyXL). It uses the worksheet's
Application property to make Microsoft Excel visible, to close it, and
so on. Using two API calls, the DetectExcel Sub procedure looks for
Microsoft Excel, and if it is running, enters it in the Running Object
Table. The first call to GetObject causes an error if Microsoft Excel
isn't already running. In the example, the error causes the
ExcelWasNotRunning flag to be set to True. The second call to
GetObject specifies a file to open. If Microsoft Excel isn't already
running, the second call starts it and returns a reference to the
worksheet represented by the specified file, mytest.xls. The file must
exist in the specified location; otherwise, the Visual Basic error
Automation error is generated. Next, the example code makes both
Microsoft Excel and the window containing the specified worksheet
visible. Finally, if there was no previous version of Microsoft Excel
running, the code uses the Application object's Quit method to close
Microsoft Excel. If the application was already running, no attempt is
made to close it. The reference itself is released by setting it to
Nothing."
Wonderful!

BUT, what I want is to reference the current open file that has the
focus in Excel - I do not want to reference the specified file,
mytest.xls. See "LOOK HERE" below.
' Declare necessary API routines:

Sub GetExcel()
Dim MyXL As Object ' Variable to hold reference
' to Microsoft Excel.
Dim ExcelWasNotRunning As Boolean ' Flag for final release.

' Test to see if there is a copy of Microsoft Excel already running.

'LOOK HERE

If ExcelWasNotRunning = True Then
MyXL.Application.Quit
End IF

Set MyXL = Nothing ' Release reference to the

End Sub

Here's my solution, in case it helps anyone:
(snipped long code)

I think you can clean that up a little. Consider the line
Set MyXL = GetObject(, "Excel.Application")
If this does not return an error, then you have gotten hold of an active
instance of Excel. So
Call DetectExcel
... Set mySheet = MyXL.Worksheets(active_sheet_name$)


is redundant - you already have the excel app.

Delete all that, and instead just put

Set mySheet = MyXL.Application.ActiveSheet
