Excel 2007 Save Workspace command prompts for Save of XLAM - Normal? Way to bypass?

Hi Experts,

I am finding that using Excel 2007's Save Workspace command prompts the user to Save an XLAM file I have developed.  I don't t believe this behavior existed in prior Excel versions.  Is this normal? And, if it is, I don't think it should be, so is there a way to bypass (i.e, don't prompt and don't Save) such files, perhaps in a modified Save Workspace command?

I expect it will require re-purposing the Save Workspace command in the:

http://schemas.microsoft.com/office/2009/07/customui

... which I can handle.  

What I need assistance with is the code I would use to Save the Workspace without prompting for the Save of either xlam files or xla files (unless, perhaps, the files are open in the Excel Window by virtue of having their "IsAddin" property set to False ...).

Hope this is clear and I appreciate any insights.

I'm not sure if the below code will block the .xla or .xlam, but I bet there is a simple adjustment that could be made to make it work for the .xla or .xlam files.  

Private Sub Workbook_Open()
 ThisWorkbook.Saved = True
 End Sub

Open in new window


Perhaps something like:
Private Sub Workbook_Open()
 workbooks("YourFileName.xla").Saved = True
 End Sub

Open in new window


or perhaps:
Private Sub Workbook_BeforeClose(Cancel As Boolean)
workbooks("YourFileName.xla").Saved = True
End Sub

Open in new window


Maybe this:

Private Sub Workbook_BeforeClose(Cancel As Boolean)
workbooks("YourFileName.xla").IsAddIn = True
workbooks("YourFileName.xla").Saved = True
End Sub

Open in new window


Good Closing Resource

Hope that helps.  Let me know if you need more help

Hi SA and thanks for posting.

Your code may be getting me around that most immediate problem but as often times happens, may have morphed into another.

I am gettting this error when opening the resulting 'resume.xlw: file:


"Office File Validation detected a problem while trying to open this file. Opening it may be dangerous."

I have looked around quite a bit on the web but can't find a solution for it.  Code follows:

Sub mySaveWorkspace(IRibbonContol, ByRef cancelDefault)

On Error Resume Next

Workbooks("myApp.xlam").IsAddin = True
Workbooks("myApp.xlam").Saved = True

ChDir BrowseForFolder

Application.SaveWorkspace

Err.Clear
On Error GoTo 0


End Sub

Function BrowseForFolder(Optional OpenAt As Variant) As Variant
     
' Thanks to Ken Puls @ http://www.vbaexpress.com/kb/getarticle.php?kb_id=284
     
     'Function purpose:  To Browser for a user selected folder.
     'If the "OpenAt" path is provided, open the browser at that directory
     'NOTE:  If invalid, it will open at the Desktop level
     
    Dim ShellApp As Object
     
     'Create a file browser window at the default folder
    Set ShellApp = CreateObject("Shell.Application"). _
    BrowseForFolder(0, "Click 'Ok' or Scroll to choose a folder to Save your 'RESUME.XLW' Workspace file. (Referenced Files will be saved in their respective folders).", 0, OpenAt)
     
     'Set the folder to that selected.  (On error in case cancelled)
    On Error Resume Next
    BrowseForFolder = ShellApp.self.path
    On Error GoTo 0
     
     'Destroy the Shell Application
    Set ShellApp = Nothing
     
     'Check for invalid or non-entries and send to the Invalid error
     'handler if found
     'Valid selections can begin L: (where L is a letter) or
     '\\ (as in \\servername\sharename.  All others are invalid
    Select Case Mid(BrowseForFolder, 2, 1)
    Case Is = ":"
        If Left(BrowseForFolder, 1) = ":" Then GoTo Invalid
    Case Is = "\"
        If Not Left(BrowseForFolder, 1) = "\" Then GoTo Invalid
    Case Else
        GoTo Invalid
    End Select
     
    Exit Function
     
Invalid:
     'If it was determined that the selection was invalid, set to False
    BrowseForFolder = False
     
End Function

Any help with this error is appreciated.  I would also like:

a) to know whether this behavior (Save Workspace command prompting for Save of XLAM files) is normal in Excel 2007 or 2010:

b) how to add code that prompts the user, asking if they want any unsaved files saved as part of the re-purposed Saved Workspace command.

Sorry, I won't make this question any more difficult ;--) !

Thanks,

Jeff

A couple of ideas come to mind.  First it sounds like this is a trust issue.  Can you set the trust center in Excel so that this document is a trusted document?  Hopefully that will solve the problem.

If not try something like this below:

So, why did you have the add in set as false previously?  One thing you might want to do after the save is completed is to turn it back into a non-add in

Sub mySaveWorkspace(IRibbonContol, ByRef cancelDefault)
On Error Resume Next
Workbooks("myApp.xlam").IsAddin = True
Workbooks("myApp.xlam").Saved = True
ChDir BrowseForFolder
Application.SaveWorkspace
Workbooks("myApp.xlam").IsAddin = False
exit sub
Err.Clear
On Error GoTo 0
End Sub

Open in new window

> First it sounds like this is a trust issue.  Can you set the trust center in Excel so that this document is a trusted document?  

XLW files are not 'primary' files that present within the Excel window where Trust Center settings can even be examined much less changed.  The best I could do was to save the XLW Workspace file to a 'Trusted Folder' location, and executing that XLW from the Trusted Location folder DID result in NOT displaying that "Office File Validation detected a problem while trying to open this file. Opening it may be dangerous" message.

That said, it's hard to believe that MS would so change the Save Workspace command in 2007 to require the use of Trusted Folders to avoid this cryptic message ... so, again, I'm wondering is this **normal** Excel 2007 behavior?  Because if it is, I'll likely put a message box to this affect in my procedure to advise users.

> So, why did you have the add in set as false previously?  

I didn't necessarily have the add-in set as False but there might be a Volatile function somewhere in the project that signals a possible change.  However, I also have this statement in the subject XLAM file (that  prompts for a save when Save Workspace is used):

[
indent]Private Sub Workbook_BeforeClose(Cancel As Boolean)
...
ThisWorkbook.Saved = True
...
End Sub[/indent]

Open in new window


... so I'd think that file wouldn't prompt for a Save regardless of any possible Volatile functions.

> One thing you might want to do after the save is completed is to turn it back into a non-add in

Thanks for the code but that's not something I would want to do in this app.

I found that my previous code was not actually producing an XLW Workspace file in the chosen folder so I have revamped that to the following:

Public folderPicked as String

Sub mySaveWorkspace(IRibbonContol, ByRef cancelDefault)

On Error Resume Next

Workbooks("myApp.xlam").IsAddin = True
Workbooks("myApp.xlam").Saved = True

GetFolder (CurDir)

ChDir folderPicked

Application.DisplayAlerts = False
Application.SaveWorkspace
Application.DisplayAlerts = True

Err.Clear
On Error GoTo 0

End Sub

Function GetFolder(InitDir As String) As String
'Thanks to Richard Schollar (& friends) at http://www.mrexcel.com/forum/showthread.php?t=294728)

Dim fldr As FileDialog
Dim sItem As String
sItem = InitDir
Set fldr = Application.FileDialog(msoFileDialogFolderPicker)
With fldr
.Title = "Select Folder to Save Workspace (Any changes in all open Excel files will be Saved to their respective folders)"
.AllowMultiSelect = False
If Right(sItem, 1) <> "\" Then
sItem = sItem & "\"
End If
.InitialFileName = sItem
If .Show <> -1 Then
sItem = InitDir
Else
sItem = .SelectedItems(1)
End If
End With
GetFolder = sItem
folderPicked = sItem
Set fldr = Nothing
End Function

Open in new window


It was also interesting to me that this code does not prompt for saving any of the open Excel files, it just saves them.

So, in sum, at this point, I'm trying to determine:

a) whether it is normal behavior for Excel 2007 to display the:

"Office File Validation detected a problem while trying to open this file. Opening it may be dangerous"

... message when opening XLW Workspace files; and

b) if the only way to preclude that is to Save it in a Trusted Location folder.

Thanks,

Jeff

I think this is a result of the Extension hardening that requires any mime format files to open with that prompt.  If you want it to stop try turning off extension hardnening for Excel.  

Important These steps may increase your security risk. These steps may also make the computer or the network more vulnerable to attack by malicious users or by malicious software such as viruses. We recommend the process that this article describes to enable programs to operate as they are designed to or to implement specific program capabilities. Before you make these changes, we recommend that you evaluate the risks that are associated with implementing this process in your particular environment. If you decide to implement this process, take any appropriate additional steps to help protect the system. We recommend that you use this process only if you really require this process.

By default, a user can decide whether to open the file when the warning message is displayed. However, the user-notification function can be set to any of the following levels by using a Group Policy setting or by using Registry Editor: •Display the warning message, and do not open the file.
•Display the warning message, and let the user decide whether to open the file (This is the default setting).
•Open the file, and do not display the warning message.
Use a Group Policy setting1.Download the 2007 Office system Administrative Template files (ADM, ADMX, ADML) and Office Customization Tool from the following Microsoft Download Center Web site:

If you are prompted for an administrator password or for a confirmation, type the password, or click Continue.
¿In Windows XP, click Start, click Run, type regedit, and then click OK.

3.Locate and then click the following registry subkey:
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Excel\Security

4.On the Edit menu, point to New, and then click DWORD Value.
5.Type ExtensionHardening, and then press ENTER.
6.Right-click ExtensionHardening, and then click Modify.
7.In the Value data box, type the value data, and then click OK.

The following list contains the value data settings that are appropriate for the ExtensionHardening setting:¿0: Do not check the file name extension and the file type, and bypass the function of the warning message.
¿1: Check the file name extension and the file type. If they do not match, display the warning message.
¿2: Check the file name extension and the file type. If they do not match, do not open the file.
Note The default value data is 1. When the value data is set to 1, the behavior becomes the same as when no registry value is set. When the value data is set to 0, the file name extension and the file content are not checked in all situations. We do not recommend bypassing this function.
8.On the File menu, click Exit to exit Registry Editor.

SA,

Can you provide a link where this "Extension hardening" is associated with XLW Workspace files?  My research indicates this is associated with Web files opened in Excel, not XLW Workspace files.

 I don't believe that MS would provide a "Save Workspace" facility within Excel that would require users to go through all of these (potentially risky) steps to use it.

Again, can someone confirm whether it is normal behavior for Excel 2007 to display the:

"Office File Validation detected a problem while trying to open this file. Opening it may be dangerous"

... message when opening XLW Workspace files?

Further to my last post, I find that I am not the only one experiencing this inappropriate Office File Validation alert (see http://social.technet.microsoft.com/Forums/en/excel/thread/cbd02bff-f1cb-4cfb-8d6a-6d8ef66d81bd?prof=required)

Only by uninstalling the 2007/2003 "Office File Validation Add-in" can this message be avoided (it does NOT appear in Excel 2010).  (Note: Since my last post, I was prompted to install Office 2007 SP3 which I did.  Now the Alert that appears makes it sound even riskier to open the file, saying that "... Opening this is probably dangerous ... " but as explained in a post I added to that referenced technet thread, the alert seems no more appropriate to XLW workspace files than it did in its pre-SP3 form.

So, back to my original reason for posting, I tested another installed XLAM and it did not prompt to be saved so I am going to check the code in the XLAM in question to see if I can find a solution here.  I will report back.

Ok, I finally found the culprit.  

When you asked: "So, why did you have the add in set as false previously?"

I answered: "I didn't necessarily have the add-in set as False but there might be a Volatile function somewhere in the project that signals a possible change.  However, I also have this statement in the subject XLAM file (that  prompts for a save when Save Workspace is used):

Private Sub Workbook_BeforeClose(Cancel As Boolean)
...
ThisWorkbook.Saved = True
...
End Sub

But, duh, that was only getting activated on Close of the XLAM (NOT the Save Workspace command). After reviewing my code, I found several places where I used the 'Application.Volatile' statement, and after amending that code to have a following 'ThisWorkbook.Saved = True' statement, the Save
Workspace command performed properly without prompting for a Save of my XLAM file.

So, while I found the answer myself, I'm giving credit for asking the question that led to the resolution.  Thanks for your help, SA,
