Merits Of VBA Protect Vs Non-Protect
Jul 26, 2006
I would like to protect the intellectual property of an application and have read differing opinions of the merits of protecting VBA code. What are the opinions of the experts on this forum? Are the password breaker programs so advanced that protecting code is a waste of time and only a hinderance to debugging and troubleshooting?
I am using MS Excel 2003 (11.5612) on XP.
I apologize if this topic has already been covered on this forum. I searched but did not find exactly what I was looking for. I am happy to review an old post if one exists.

Some sensitive data is held on worksheets that are used by people that do not have access to see the data.
It would be most convenient to keep the data in these worksheets but hide it from view of the users.
Is there a way to password protect a users ability to unhide a column?

I have a sheet that is password protected. I have this code attached to a command button. It will unlock the worksheet, autofilter it, print it, unfilter it, and password protect the sheet again. However it is protecting it without a password. I need to have it protected with the password so that someone will not be able to just go to tools to unprotect the sheet.
Private Sub CommandButton1_Click()
ActiveSheet.Unprotect "rainforest"
Columns("O:O").Select
Selection.AutoFilter
Selection.AutoFilter Field:=1, Criteria1:=">0", Operator:=xlAnd
ActiveWindow.SelectedSheets.PrintOut Copies:=1, Collate:=True
Selection.AutoFilter Field:=1
Selection.AutoFilter
ActiveSheet.Protect DrawingObjects:=True, Contents:=True, Scenarios:=True _
, AllowSorting:=True, AllowFiltering:=True
End Sub

Is there a button to protect a workbook in the same way that you can protect sheets? For example, I don't want a user to be able to touch any locked cells and there's multiple worksheets in this workbook. Do I have to go to each worksheet and protect them or is there a button to protect all worksheets at once?

I have created an Excel workbook and protected the sheet. However, it still allows me go into the VBA section (Alt+F11) and edit away to their heart's content.
How can I protect my spreadsheet, as well as the VBA associated with it?

My user form has a line of code that protects the sheets and does not allow any changes and selection of cells. It worked great on my personla computer.
Running the file on another computer the code does not protect the sheet. The strange thing is that if I go the Tools>Protection> the options is set to Unprotect. That measn that the code actually has protected the sheet but I am still able to make chages. If I manually unprotect and again protect the sheet, it is protected till the time close the file and open it again.

Excel file 1 has:
Sheet 1: Account numbers and balances
Sheet 2: Mapping information detailing what account in file 1 is to go to a different account number in file 2.
Excel file 2 has:
Lots of sheets where information is to be keyed in.
This is a very manual process with lots of data entry to input into accounting forms I send to our head office. The "file 2" has sheet protection on all sheets so that formats, data, columns etc etc cannot be altered and only certain fields updated.
I think I have successfuly written my scripts to loop through the account values and map those to all spots in all sheets they are referenced to on the mapping document, however I am getting an error message that the "cell or chart you are trying to change is protected and therefore read-only".
Basically I look through the sheet and look for my mapping code, if that matches, I add the balance to the exisitng value of the cell, in the next column.
i.e. if B2 has the corresponding code I will add the balance to the current value of cell C2.
This is an extract of the code where I am looking up the sheet:
Dim ws As Worksheet
For Each ws In Sheets
If Left(ws.Name, 2) "OP" Then
Dim rg As Range
Dim cl As Range
Set rg = Range("A1:IV65536")
For Each cl In rg
If ActiveCell.Locked = False Then
If cl = kessanid Then
cl.Offset(0, 1).Value = acctvalue
End If
End If
Next cl
End If
Exit For
Next ws
It may be that because the sheet is protected as a whole nothing can be done but I was hoping that because I am going to the specific cell which allows input I should be able to do this.

I've been given this before but unfortunately i lost a hard drive so all the codes i was given from folk on here have been lost.
I had one in particular, where it would protect my workbook when closing so when it was reopened the user had to use a password in order to change protected cells. This was because certain colleagues would forget to protect the workbook and left it open to accidental damage.

Excel 2007. I have the workbook structure protected with a password. When I open the file, the worksheets are sized to file the normal Excel window space. When I email the spreadsheet to a customer who also has Excel 2007, the worksheets are small and she has to use the arrows to navigate.
We tried changing her view and that didn't work. She does not have the arrows available to resize the window. The only way I could fix it for her was to remove the workbook structure protection. I'm nervous about leaving it this way for our entire customer base as they could unhide hidden sheets and even delete them. Has anyone else experienced this? One more thing, customers that have an earlier version of Excel have not had this problem. This workbook is save as an .xls to be backward compatible.

I am using the following code to protect/unprotect a sheet in a tool that i am working on, which seems to work great. It unprotects the sheet runs the code inbetween the two liens of code and then protects the sheet again.
VB:
ActiveSheet.Unprotect Password = "mypassword"
ActiveSheet.Protect Password = "mypassword"
The issue I am having is if i want to go in and edit the sheet without running the code it will not let me. When I go in and type the password to unprotect it says it is invalid. I have typed it exactly how the code reads. I have even tried including the quotes but no luck.

How can I protect by workbook from ex-employees and the competition from using (I am aware of the weak security measures Excel offers, but something is better than nothing)? Each worksheet is password protected to slow down novice Excel users. However, ex-employees know the password. I was thinking if there was a way to have a changing password (which only a couple people would know) or have the worksheet look for a hidden file on our network, that one of these methods (or another) might work.

I was wondering how you can protect a formula but still allow editing in the cell. Right now I have certain columns locked while allowing others to be edited. I have a formula in one column that needs to be edited if need be but if they make a mistake and hit delete then my formula disappears and it throws the whole sheet off. Is there a way to protect your formula maybe by putting it in a different cell that can be locked and referencing the cell where they can input?
