Hi,

I've been working on some VBA in MS Word to that requires access to information in an Excel workbook. I'm having trouble when Excel is closed before my procedure is called. I'd like to avoid dependence on the user opening Excel before the application is used; consequently, Excel may or may not be open at the time the Word application is used.

My current environment is Windows 7 Pro, MS Office 2010, all updates current. No compiler errors in VBE for Excel or Word.

With Excel open prior to running Test_OpenWorkbook, the code below successfully opens the workbook as intended.

However, if Excel is closed I've observed the following:

  1. Prior to starting the function, I've assured that Excel is not running in the Task Manager.
  2. When I run Test_OpenWorkbook, Excel is started by OpenWorkbook as intended.
  3. A window in Excel does open showing MyWorkbook.xlsm but does not show any content in its window (no grid, no tabs, just the normal background color of a worksheet).
  4. Output to the Immediate Window is:
    2018-06-01 10:01:53 ERROR - -196347 Method 'Open' of object 'Workbooks' failed(-2147417851)
    2018-06-01 10:01:53 FullPath = C:\Users\bvolkert\Documents\MyWorkbook.xlsm sOpenMode = Normal
    oEWKb is Nothing
  5. Task Manager shows an Excel process running with the CPU at 25% while the status bar is showing CPU varying between 29% and 42% and Physical Memory varying between 39 % and 44%.
  6. If I close the empty MyWorkbook window in Excel, Task Manager continues shows an Excel process running with the CPU at 25%.
  7. I cannot close the Excel window normally; but, I can (and do) kill the process with Task Manager.

By stepping through the code, I know that the error triggering the ErrorHandler code is:
Set oEWkb = appExcel.Workbooks.Open(sFullPath).


After ending the Excel process in Task Manager: I can copy the constructed FullPath from the Immediate Window and paste it into the address for Windows Explorer and the file opens normally. The file has a lot of formulae that use VBA in my Personal.xlsb and it takes a few seconds for the calculating to end. This code appears to be functioning normally and I don't believe it should be any sort of contributing factor; but, may very well be.


I can open
MyWorkbook.xlsm by all the normal methods (double-clicking, File / Open, etc.). So, I don't think there is anything wrong with the file other than not being small.

If I point the Function a small Workbook (14 KB), the Functions below work just fine. Opening the "real" Workbook (1358 KB) manually works pretty quickly; but, it does take a few seconds for the calculations to complete. I'm a bit concerned because I expect the "real" Workbook to grow substantially. (I'm using a workbook instead of a database because the users can deal with a workbook and will wig-out if I try getting them to be dependent on a database - that can come later.)

So, I think I'm looking for a solution that allows Excel to open a workbook in the face of all those calculations in the workbook. Since the VBA runs to the Workbooks.Open statement and does not get through it, I suspect I need something to prepare the environment for it to be successful or use some of the other arguments in the Workbooks.Open(. . . . . ) statement. I'm also open to changing the Workbooks.Open statement to something else; but, in the end, the workbook does need to be open.

I've tried the following:
  • Repairing MS Office 2010
  • Disabling all add-ins in Excel
  • Not loading any Add-Ins in Word (that I know of)
  • Restarting
  • Shutdown
  • Remove battery from laptop and cold-booting
  • Latebinding = True and = False
  • Adding delay statements (e.g. Sleep(5000) ) before and after the Workbooks.Open statement
  • Closing one eye, tongue to left and to the right

Thanks for any direction or suggestions you can offer.

If you start Excel programmatically, no startup workbooks will be loaded unless you used Shell to start Excel.

Rory,

Wow. That was fast. I really appreciate it. I wish I had posted my question a week ago.

If I understand you correctly, programmatically starting Excel with CreateObject will not start my Personal.xlsb and consequently, the formulae in the spreadsheet are not getting any response from the functions in the Personal.xlsb. I'm a little new to the "Shell" game and want something that will be likely to work for anyone having MS Office installed.

Based on your suggestion, this seems to be working:

Code:
  On Error Resume Next
  Set appExcel = GetObject(, "Excel.Application")
  If Err Then
    bExcelWasRunning = False
    Shell ("Excel.exe")
    WaitAFewSeconds 3
    Set appExcel = GetObject(, "Excel.Application")
  Else
    bExcelWasRunning = True
  End If
  
  On Error GoTo ErrorHandler

Note: It did not work until I added the brief wait after the Shell statement. WaitAFewSeconds is provided below and does just what it seems to do. I also tried DoEvents etc. But no joy.

Code:
Public Sub WaitAFewSeconds(Optional ByVal Seconds As Long = 3, Optional ByVal ReportInterval As Long = 0)

  Dim vStart As Variant
  Dim lSecondsRemaining As Long
  Dim lReportTime As Long
  Dim lEndTime As Long
  Dim bReporting As Boolean
  
  vStart = Timer
  lEndTime = vStart + Seconds
  lSecondsRemaining = Seconds
  If ReportInterval = 0 Then
    lReportTime = lEndTime
    bReporting = False
  Else
    lReportTime = vStart + ReportInterval
    bReporting = True
  End If
  
  Do While Timer <= lEndTime
    If bReporting Then Debug.Print CStr(lSecondsRemaining) & " seconds remaining."
    Do While Timer <= lReportTime
      DoEvents
    Loop
    lReportTime = Min(lReportTime + ReportInterval, lEndTime)
    lSecondsRemaining = lEndTime - lReportTime
  Loop
  If bReporting Then Debug.Print "WaitAFewSeconds is finished."
    
End Sub

You can also use createobject and then explicitly open the personal macro workbook prior to opening your main workbook.

I think the Shell is the better option for me. I'm working on one set of modules that I use as a basis for my work in all MS Office applications. I suspect that the Shell approach is likely to be similar from one application to the next. Ultimately, I plan to have a Global template for each application that I support and I'm hoping the code can be the same in all of them. Right now it is in Personal.xlsb when I run Excel; but will end up elsewhere. I also want to minimize the confusion of users that might have their own Personal.xlsb. Your advice was perfect. Thanks again.
