Hi Mark,
We may be too far getting ahead of the problem.
"Workbooks" is a collection. So is "Sheets".
Once you get a handle to the object it is easy to find the workbooks and
sheets within.
In the code below MyXL is the object name.
Copy & paste the code into a new workbook and run the sub
"ListWBSheetNames".
' Declare necessary API routines:
Declare Function FindWindow Lib "user32" Alias _
"FindWindowA" (ByVal lpClassName as String, _
ByVal lpWindowName As Long) As Long
Declare Function SendMessage Lib "user32" Alias _
"SendMessageA" (ByVal hWnd as Long,ByVal wMsg as Long, _
ByVal wParam as Long, _
ByVal lParam As Long) As Long
Dim MyXL As Object ' Variable to hold reference to Microsoft Excel.
Dim ExcelWasNotRunning As Boolean ' Flag for final release.
Sub GetExcel()
' Test to see if there is a copy of Microsoft Excel already running.
On Error Resume Next ' Defer error trapping.
' Getobject function called without the first argument returns a
' reference to an instance of the application. If the application isn't
' running, an error occurs.
Set MyXL = Getobject(, "Excel.Application")
If Err.Number <> 0 Then ExcelWasNotRunning = True
Err.Clear ' Clear Err object in case error occurred.
' Check for Microsoft Excel. If Microsoft Excel is running,
' enter it into the Running Object table.
DetectExcel
' Set the object variable to reference the file you want to see.
Set MyXL = Getobject("c:\vb4\MYTEST.XLS")
' Show Microsoft Excel through its Application property. Then
' show the actual window containing the file using the Windows
' collection of the MyXL object reference.
MyXL.Application.Visible = True
MyXL.Parent.Windows(1).Visible = True
Do manipulations of your file here.
' ...
' If this copy of Microsoft Excel was not running when you
' started, close it using the Application property's Quit method.
' Note that when you try to quit Microsoft Excel, the
' title bar blinks and a message is displayed asking if you
' want to save any loaded files.
If ExcelWasNotRunning = True Then
MyXL.Application.Quit
End IF
Set MyXL = Nothing ' Release reference to the
' application and spreadsheet.
End Sub
Sub DetectExcel()
' Procedure dectects a running Excel and registers it.
Const WM_USER = 1024
Dim hWnd As Long
' If Excel is running this API call returns its handle.
hWnd = FindWindow("XLMAIN", 0)
If hWnd = 0 Then ' 0 means Excel not running.
Exit Sub
Else
' Excel is running so use the SendMessage API
' function to enter it in the Running Object Table.
SendMessage hWnd, WM_USER + 18, 0, 0
End If
End Sub
Sub ListWBSheetNames()
Dim wb, MySheets
GetExcel
For Each wb In MyXL.Workbooks
Debug.Print wb.Name
For Each MySheet In MyXL.Sheets
Debug.Print MySheet.Name
Next
Next
Debug.Print MyXL.Workbooks.Count, MyXL.Sheets.Count
End Sub

| Thanks for that John
|
| However, although it gives me the window handle for all the Excel
instances',
| what I then need to do is to obtain the worksheet names within the Excel
instances'.
|
| I do not know how I can examine the contents of the Excel workbooks in
each instance
| with only the window handle.
|
| What I really need is the Application handle for each instance so that I
can use
| Application.Workbooks(x).Worksheets(y).name
|
| Any ideas ??
|
| Cheers,
| Mark.
