My colleague and I have been on a six month quest for a VBA macro that can run in a Read-Only, password protected PowerPoint.
Is it possible or will PowerPoint always block the VBA macro from running in the presentation, because of the read-only status?
Private Sub CheckBox1_Click()
Dim ppShp As Shape
Dim eff1 As Effect
Dim ani1 As AnimationBehavior
With ActivePresentation.Slides(1)
Set ppShp = .Shapes("Oval 4")
Set eff1 = .TimeLine.MainSequence.AddEffect(Shape:=ppShp, effectId:=msoAnimEffectAppear)
End With
End Sub
I tried using If ReadOnly = True Then conditions.
I want the user to use the macros and save, but not edit beyond that, or to open and 'look under the hood'.
(It's all for an educational program)
We get
Run-time error '-2147467259 (80004005)'
Presentation (unknown member) : Invalid request. Presentation cannot be modified.
Perhaps as a work around you could save a copy of the original read only presentation, run your macro on the new version and then save the new version as read only?
Hello this might be too late but if I understand you correctly, you want that other users can read, execute macros but not able to read the code behind it. Saving should be okay.
The macro that you used should be password protected. First go to the editor, select the macro and view the properties/protection and set up a password
Then after you are done, close the file. Right Click on the file/properties and check readonly. Users will then have access to the macro, not being able to see what code is behind it and can save it.

I have a requirement for VBA script in Microsoft Word to pause so that the user can select text that will be copied to the clipboard so that it can exported to an Excel file. The user will make a number of selections and finally indicate he/she is done when the contents of the clipboard will be copied to a template Excel file.
I have the code working to copy each selection to the clipboard and then all rows to the Excel file. But I need assistence in figuring out how to pause the code to allow the user to make the selection and then restart the code to copy the selection to the clipboard. I am able to get the userform with toggle switch to switch states and labels when pressed. But have not figured out how to pause the VBA code to allow the user to navigate to the next section of the Word document for the next selection.
The Stakeoverflow question/answer below appears to address this requirement but I have not been able to get it to work. It appears that the code is incomplete.
Pause VBA macro, allow user to make a selection, and restart where it left off
Can someone provide example VBA code that accomplishes this?
Your assistence is much appreciated as I have been beating my head against the wall and it is starting to hurt!
There's no way in VBA to "pause" a macro. Code must run to completion... Unless there's a command for user input.
Input can be requested via the InputBox and MsgBox methods, but those block access to the document because they're modal. A UserForm, however, can be set to display as non-modal, meaning it stays on top, but doesn't block access to the document or the application features. Since you're already working with a UserForm, this can be implemented relatively easily.
In the small example below, the Continue button runs the code to perform an action on the user selection. When Done is clicked the entire code is exited and the form unloaded.
Code behind the user form
Option Explicit
Private Sub cmdContinue_Click()
Debug.Print Selection.Range.Text
End Sub
Private Sub cmdDone_Click()
Me.Hide
End Sub
Private Sub UserForm_Activate()
'Position the form near the top-left of the window
'So that the user can work with the document
Me.Top = Application.ActiveWindow.Top + 50
Me.Left = Application.ActiveWindow.Left + 50
End Sub
Code in a regular module
Option Explicit
Sub DisplayModeless()
Dim frm As frmModelessForInput
Set frm = New frmModelessForInput
frm.Show False 'Display as non-modal
Set frm = Nothing
End Sub
Relative VBA newbie here. I created a new Module "QCDataRefresh" with a Public Sub "RefreshExcel" that is designed to open an Excel spreadsheet (housed on my network drive) in the background and refresh it. This is done in order to refresh the many data links contained within said spreadsheet.
Here is the code for this Sub:
Public Sub RefreshExcel()
Dim appExcel As Object
Set appExcel = CreateObject("Excel.Application")
appExcel.workbooks.Open ("\\renssfile2\shares\Supply Chain Project Management\QCData.xlsx")
appExcel.activeworkbook.refreshall
Set appExcel = Nothing
End Function
Running this gives a run-time error '1004': "Application Defined or object-defined error. Debugging seems to highlight the line of code "appExcel.activeworkbook.refreshall". Not sure why though?
Additionally, I am also attempting to create a button in Access to run this from my dashboard. To do this, I created a new button, and created a new Event Procedure for this entitled, "Command101_Click".
The following is the code for that Event, which attempts to run my RefreshExcel Sub upon clicking the button:
Private Sub Command101_Click()
QCDataRefresh.RefreshExcel
End Sub
When I run this Event, I would expect it to give me the same error from my refresh Function above. However, instead it opens a window asking me to select a Macro. I'm unsure what my mistake is here, but I'm sure that it must be a simple oversight. Thoughts on this as well?
Thanks all!
I think the problem is that the workbooks.open method returns a workbook.
Try this:
Public Sub RefreshExcel()
Dim appExcel As Object
Dim excelwb As Excel.Workbook
Set appExcel = CreateObject("Excel.Application")
Set excelwb = appExcel.workbooks.Open ("\\renssfile2\shares\Supply Chain Project Management\QCData.xlsx")
excelwb.refreshall
Set excelwb = Nothing
Set appExcel = Nothing
End Sub
Whenever I have unexpected and unusual issue\error for using excel to output to or read from I allways try the following, especially when the code breaks in the middle and doesn't get to the line where you close the spreadsheet and close the Excel object from memory.
So close your spreadsheet and any Excel instances and objects you may have as follow:
Close all Excel files and excel program if you have any open
Go to the Task Manager (by doing Alt+Ctrl+Del) then select Task Manager
Go to processes tab
Sort by process name
Look for any Excel.exe in the list and force close them all one by one
Let us know.
Have Excel (2010 in my case but I think it will be the same also in other versions) with two workbooks. Save first one with name "1.xlx" (example) via Save As dialog. Save second one with the same name "1.xlx" to different location. Excel will not allow it with following warning message:
"You cannot save this workbook with the same name as another open workbook or add-in. Choose a different name, or close the other workbook or add-in before saving."
So far so good. But my problem is that I need to invoke dialog via VBA. I am using following code:
Sub test()
Application.Dialogs(XlBuiltInDialog.xlDialogSaveAs).Show
End Sub
Now I am trying to save second workbook (with the same name to different location) but when I click to 'Save' button nothing happen, no warning message. If I wouldn't know what is wrong it would be very difficult to tell. I didn't change any setting (there is nothing as DisplayAlerts set to true or so). Any idea how make SaveAs dialog invoked via VBA to display similar warnings?
I'm not sure why that doesn't give you an error, but it doesn't me either. If you use Application.FileDialog, you can get that error.
Sub testts()
With Application.FileDialog(msoFileDialogSaveAs)
.Show
.Execute
End With
End Sub
Or you could use GetSaveAsFileName and check the names of all the open workbooks and generate the error yourself.
Can you try with the below code on starting on your code.
Application.DisplayAlerts = True
We receive Excel files daily from our field offices which I have to clean and re-format (about 110 columns and 500 rows-worth) using VBA.
I need to save my VBA as a macro so we can use it to clean up all the workbook we receive by running the macro and saving the edited sheet as a new worksheet by getting the name from UserForm Combobox items.
Where exactly should I store the VBA snippets? I mean when I open the Visual Basic panel, I have these three options:
Running The Code From Microsoft Excel Object :Sheets1(Sheet1)
Running the Code From An Inserted Module
Running the Code From User Form
If I am supposed to use options 1 or 2, how can I call the UserForm for saving the sheet?
I Recomend you to use modules (Option B)
Option C goes with option B, ill explain, you can create a sub in a module in option B, then you can do:
UserForm1.show
In Option B I would writte this code, but before trying this i recomend you to understand a bit more of vba
sub ClearWBs()
'opening workbook
Workbooks.Open Filename:="c:\book1.xls"
'your code
'your code
'below code for saving and closing the workbook
Workbooks("book1.xls").Activate
ActiveWorkbook.Save
ActiveWorkbook.Close
end sub
Use Module:
If your VBA code focusses on data summarization and manipulation I suggest you use a Module.(example is what you have described in your question).
Use Form:
If what you wan't to do requires a GUI(Graphical User Interface) then you'll have to resort to Form where you can design your GUI. (example is if you have many fields that the user needs to fill-up with distinct values in which you provide the choices)
Use Excel Object:
If what you wan't to do has something to do with events happening on Worksheet and/or Workbook, like for example whenever you add sheet the macro runs, or when you open or close the workbook the macro runs then you will have to write the macro in the Excel Object.
This is basically what i have in mind, hope this helps.
If you receive files that do not contain VBA and you need to apply the same code on those files all the time then I propose that you either save that code in your personal workbook.
You can see how to do that here: http://office.microsoft.com/en-ca/excel-help/copy-your-macros-to-a-personal-macro-workbook-HA102174076.aspx
This is nice because you can also tie it to keyboard shortcut or just have it always ready for you to use.
The disadvantage is that it will only be set up per user session per computer. What you can do is have that code all set up in a module and then import it into your personal workbook if you change session or if someone else has to do it.
Once it's done, you will not have to include the module in your files your receive again.
I know that even private vba scripts can be called by the user, such that making it "private" in fact only hides its name.
However, is there a way to set up a macro so it is only runnable if you are inside that particular VBA project? Not from Excel and not from any VBScript or the likes.
If you want to lock down the code you could
make the code private so the macro names areen't exposed
lock the protect, and then test that the project is actually unlocked before letting the code run
The sample code below checks that the VBA in the host workbook is not protected before running
Does this meet your needs?
Private Sub TestMe()
Dim objVB As Object
Set objVB = ThisWorkbook.VBProject
If objVB.Protection = 0 Then
Call TestSub
Else
MsgBox "Sorry sport - unauthorised", vbCritical
End If
End Sub
Private Sub TestSub()
MsgBox "Project unprotected - i've been run", vbOK
End Sub
Honestly, there is no foolproof way around it. You can have certain checks but that's all you can do.
If you are sure that a user will not have access to VBA Code then what brettdj suggested is the best way to go ahead. Protect your project. One cannot run a macro from Excel or from outside Excel if one doesn't know the macro name ;)
The basic intention of making a macro Private is not to prevent it from running but making it invisible to the user. Mostly, the only macros that needs to be private in Excel are the inbuilt Worksheet or Workbook events or macros referred by other macros which necessarily don't need to be accessed by the user. A user can still access them from outside VBA if he or she wants to.
Having said that, you can restrict (But not STOP - Not referring to disabling your macro security) the macros from running. Pass an authorization FLAG. Only when it receives an "Authorization", will it run.
For Example
Option Explicit
Private Sub Sample(Auth As Boolean)
If Auth = True Then
'~~> Your macro code goes here
End If
End Sub
Now if you want this macro to be called from VBA then you have to call it like this
Sample True
or
Call Sample(True)
This will ensure that the above macro will only run when you allow it to.
Would this method prevent user from running this from VBS?
NO. It won't. However, it won't run till the time the user specifies or gives the "Authorization"
HTH
