VBA Password Crack/Hack - How Easy Is It?
Dec 10, 2008
Ok, so I'm a little cheezed that I've been volun-told to give up an economic model that took me over 8 months to develop to a few investment bankers that will likely sell it to the highest bidder. Of course, with no credit to me.
I've already taken a few of the necessary steps to lock it down.
Examples:
- Lock/hidden cells along with sheet protection (with password) - to prevent viewers from seeing the formulas I used.
- protect workbook (with password) - to prevent copy/paste of the sheets
- VBA - Tools - VBA Project Properties - Protection - Set password - to prevent viewing of the macros
- Hiding sheets using "Very Hidden" in VBA - to prevent viewing of sheets in general.
I guess my real question is, when this is all said and done, how easy is it for someone to break through all the passwords that I've set up in the workbook? If it's ridiculously easy, how do I prevent it (if at all)? What else can I do?

If I have a very long password would this make unprotecting the sheet harder?
Or do the programs available on the net extract the data from else where - Making it pointless choosing a complicated password?

Is there an easy way to add every sixth column?
Example:
=A1+A6+A11+A16
Then
A2+A7+A12+A17
I am all the time doing something like this. Is there a formula or something of that nature that would sum every 6th cell down starting a a given point?

I'm having real trouble selecting a series of rows based on variables for the purpose of cutting them and pasting them elsewhere in the spreadsheet. For example, if this is my spreadsheet
row
2 I Hate
3 Bill
4 O'Reilly
I want my code to select the range of 2:4, cut them, and paste them elsewhere but I want 2:4 to be variables. For example
Fun = 2
Stuff = 4
Rows(Fun:Stuff).Select
Selection.Cut
But doing "Rows(Fun:Stuff).Select" does not work at all. If you do Rows(Fun).Select, this works to select Row 2, but I can not use the variables to select a range.

This is the code I have so far:
Sheets("Oven Codes").Select
Rows("3:3").Select
Selection.Delete Shift:=xlUp
Sheets("Item Edit").Select
Range("I12:J12").Select
What I would like to do is have VB look to E1 to determine which row to delete. E1 could say 5 or 25.

I have many files that has a filepath references in the cell values, for example:
='\serverfolder1subfolder2[Filename.xls]Sheet'!$B$82
Is there a way to change all the references to direct to another place?
Filenames don't change, only the '\serverfolder1subfolder2 path

I have a workbook with over 100 worksheets (all worksheet tabs are named). Since the tabs are not sorted in a numerical order (they are grouped by departments hence the numerical tab order does not apply), can I search for a particular worksheet tab using a search function? The CTRL F function doesnt allow searching for worksheet tabs. At the moment, I have to go through the tab names in order to find one particular tab.

I have entered VBA code and tested it with success. If I then save & close the excel file and then re-open it, the mask time entry is not saved (time does not appear correctly after input) and per instructions I have designated (and am using) the cell input range.

I was wondering if there was an easy way to copy columns (headings) and the formulas to a new sheet. I'm currently working on Sheet 1, need to copy everything onto a new sheet so I can keep things separated by week..
Example, Sheet 1 is Week October 30th, would like my 2nd sheet to have same exact headings and formulas which I would then rename to Week Nov. 1st etc..
Also, is there a way that I can then copy the 4 sheets that would make up a month into a new spreadsheet so I can then start December...

I am trying to calculate weighted average cost for a list of thousands of items.
I will try to explain this as best I can.
Column A is item. Column B is Mode. Column C is Volume. Column D is Cost
There are only 2 Transmode Per Item. So each item is pretty much listed twice and I need to calculate the weighted average cost per item.
I know how to use the SUMPRODUCT function to calculate weighted average and could slowly go through the spreadsheet item by item calculating this, but is there a way to do this with some sort of formula? Similar to a Subtotal that would recognize each change item and calculate the Weighted Average at that change.

I have a spreadsheet that lists values for different grid lines. On top of each set of data, I have labels each line "Line A", etc. I want to put in possibly a pull down menu at the top of the sheet that the user could use to jump to whichever line they were interested in viewing. For example, if the user needs data from Line L, they could select Line L from the drop down menu and the spreadsheet would jump down to that area.

You could use:
If ActiveWorkbook.Sheets.Count < 17 Then
Application.CommandBars("Workbook tabs").ShowPopup
Else
Application.CommandBars("Workbook tabs").Controls("more Sheets...").Execute
End If
The code doesn't do anything on my excel workbook which currently has like 20 workbooks, and it grows daily by like 4 or 5 worksheets.

When opening a new Excel file, it is asking me for a password to an old excel file that was password protected, which I have deleted from my computer. It is still asking for this password every time I open a new or existing file. When I hit cancel it lets me open the file.

I am havng problems with the belwo macro code -
Range("G7").Select
Selection.Copy
Workbooks.Open Filename:= _
"Q:PublicPAYMENTS Q&RREPORTSSuspense Activity BUSINESS2008 - Suspense BUSINESS - Activity Reports2008 Avon.xls"
Application.CutCopyMode = False
ActiveWorkbook.Save
ActiveWindow.Close
End Sub
When i open the workbook it requires me to insert a password, i tried to type this but excel will not follow keystrokes, i then inserted the password in cell G7 which i then copy and paste, which you can see the copy at the beginning of the macro.
Is there a way where you can get it to insert the password so i can open the workbook in a macro.
What im trying to do is save 26 suspense spreadsheets by just clicking on a macro.

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

find the attached workbook
I have a Database and user form, in the user form i have a field named “Vehicle No” this is a combo box from which a user needs to select the Vehicle numbers, and all these are working fine now, I need your help in the following:
When user selects the second field named "Select Vendor name" i need a pop up window which shows all the Vehicles belongs to the vendor which they have selected, and with the popup window user selects the vehicle number then the Vehicle number combo box should be filled.
Currently users have to select by scrolling through Combo box which takes long time and difficult to find by scrolling.

When using the a file with VBA based on a button is there any way to add a password to that file at the same time?
That way it can be opened by anyone?
The code below works fine but the user can open the file in fact anyone can once they press the command button I want to add a password so when the file is reopened it requires a password?
Is this some thing vba even does?
Private Sub CommandButton1_Click()
Const PTHNAME As String = "C:Feedback"
Dim FileNameWithDate As String, x As Integer
FileNameWithDate = Format(Date, "yyyymmdd")
x = 1
If Dir(PTHNAME & FileNameWithDate & ".xls") = "" Then
ActiveWorkbook.SaveAs Filename:=PTHNAME & FileNameWithDate & ".xls"
Else
Do Until Dir(PTHNAME & FileNameWithDate & x & ".xls") = ""
x = x + 1
Loop
ActiveWorkbook.SaveAs Filename:=PTHNAME & FileNameWithDate & x & ".xls"
End If

First, I know passwords are easy to break. The point is only to keep the average Excel user in a dept of 3 from accidentally damaging the data.
Normally I hardcode passwords to view xlveryhidden sheets.
But this workbook is for a dept head who has standard password(s) he uses to open or edit a file. I would like to capture these passwords and make it the same password(s) to view a hidden sheet.
This way if he ever changes the password to open/edit it will automatically change the password to view the hidden sheet(s).

How to set a password before executing any action.
For example, I have "cancel" button in my userform. If i click "cancel" it unloads the form. Instead of that i need a password prompt. so when i click the "cancel" button ,it should ask for a password. only if i provide the correct password then only the form should be unloaded.

I was working on a workbook that unhides certain sheets depending on who's logged in. It seems to work fine. However, after it's run (and sheet2 has been unhidden), when I go to unprotect the workbook, the password ("test") no longer works.

I have an excel spreadsheet that has password to open it as well a read only prompt. What I would like to happen is after the user has typed in the password, clicked ok, and then clicked either "yes" or "no" for read only or not that a specific named macro immediately is run.

I have a workbook where each tab represents a 'base.' You can select which base to view by selecting an option from a drop down box on a menu page.
The data for each base is of a confidential nature so I would like to password protect each tab so that it asks for a password BEFORE the page opens. I don't think Excel has the functionality to do this unless I make the pages 'Very Hidden'?

I have a excel document with 5 tabs (sheets) and, because different people work with a different tab (sheet), I want to lock each tab (sheet). I want the tab to be visible on the tab bar but when you click on it you will not be able to see the content of that tab (sheet) until you provide the right password (each tab with a different pasword).
