Outlook vba test for excel already open

I have an Outlook macro that opens an excel workbook when an email arrives to a specific folder - but if excel is already open it opens another instance - also if the desired workbook is already opened, it opens a read-only copy.

This is what I have:

Dim xlApp As Excel.Application
Dim wb As Excel.Workbook

Set xlApp = New Excel.Application
Set wb = GetObject("sampleworkbook.xls")

How do I:

If excel isn't open, open it and open the workbook.
If excel is open, but the workbook isn't, open the workbook.
if excel is open, and the workbook is open, activate the workbook?

Thanks.

Something like this:
Code: 
[blue]On Error Resume Next
Set xlApp = GetObject(, "Excel.Application")
On Error GoTo 0
If xlApp Is Nothing Then ' Err.Number <> 0 Then
    Set xlApp = CreateObject("Excel.Application")
End If
On Error Resume Next
Set wb = xlApp.workbooks("sampleworkbook.xls")
On Error GoTo 0
If wb Is Nothing Then
    Set wb = xlApp.workbooks.Open("sampleworkbook.xls")
End If[/blue]

Enjoy,
Tony

Just out of curiosity, and with the hope of learning something myself, why do I never see any code using Tasks for this? Since 2002, Office applications have access to Tasks, like this:

Code: 
Dim xlApp As Excel.Application
Dim wb As Excel.Workbook

If Tasks.Exists("Microsoft Excel") = True Then
   Set xlApp = GetObject(, "Excel.Application")
Else
    Set xlApp = CreateObject("Excel.Application")
End If
Tasks are "tasks" running on the system, and include a surprising amount of things.

Code: 
If Tasks.Exists("Calculator") = True Then
    Tasks("Calculator").WindowState = wdWindowStateNormal
End If
for example checks to see if Calculator is running, and if it is, brings its window state to Normal.

Or:
Code: 
Dim aTask As Task
For Each aTask In Tasks()
    If aTask = "C:\TestData" Then
        aTask.Visible = True
    End If
Next
This checks to see if there is a Windows Explorer tasks AND that the current folder in Explorer is "c:\testdata". If there is, it makes Explorer visible.

Note that Explorer Tasks are named by the folder. Regardless of what you do in Explorer, it always has a current folder. Even if it is the default "My Documents".

Tasks (as objects) have useful properties and methods. You can move it, resize it, or send it window messages.

An example from Help.
Code: 
Dim taskLoop As Task

For Each taskLoop In Tasks
    If InStr(taskLoop.Name, "Notepad") > 0 Then
        taskLoop.Activate
        taskLoop.SendWindowMessage &h111, 11, 0
    End If
Next taskLoop

Anyway, in all the threads I have seen about getting/setting other applications, I do not think I have ever seen anyone use Tasks. To the real gurus (PHV, Tony, Skip et al), is there something not quite right with using Tasks?

When dealing with automation the Tasks collection is not so useful, IMO.

You may want to take a look at what Windows considers Tasks.
Code: 
Dim aTask As Task
For Each aTask in Tasks
   Selection.TypeText Text:=aTask & vbCrLf
Next
Assuming (of course!) you are in Word. Here is what is typed. I have IE open to this thread page, and a blank Word document, running the code above from the VBE (thus, I think, the first Task - rather logically - is "Run Sub").

Some of these can of course be seen in Processes, under Task Manager. But i have no bloody idea what:

Insert

Insert

OR

Toolbar 32779
Toolbar 32779
Toolbar 32779
Toolbar 32779
File

mean as "Tasks".

Shrug.

However, as a means to get an instance of Excel (for example) I use Tasks. I just do not know if this is essentially moot, regarding whether it is any "better" or "worse" (efficient vs inefficient???) than error trapping the result of GetObject.

Ooops, just scanned up and saw PHV's post. OK, you are most certainly a source I will listen to. Why?

Oh....never mind. Because it does go through all that other crap.

And there ya go.
