How Protect Sheet With Password That Cannot Be Cracked |
How Protect Sheet With Password That Cannot Be Cracked - Excel |
|
As long as I'm posting, I have to ask this question. I'm sure others here have tackled this one!
As many of you know, there are easily-available software/macro app's that will quickly find the password and unlock a password-protected Excel worksheet.
This effectively makes the password Protect sheet function, kinda useless if my goal is to keep hidden all the code and function in cells that I consider my intellectual property.
QUESTION:
Is there any "uncrackable" method where I can hide my cell functions and the password cannot be cracked by any method that is easily available to the "man on the street" who is searching the internet for ways to crack into a password-protected Excel workbook/worksheet? My meaning is that I'm OK with a method that can be cracked by say some experts at the FBI or CIA, but I at least want something at minimum is impenetrable by the vast majority of Excel users and Excel programmers.
Oh, I had better mention that of course I want to allow the user to be able to interact with the cells in the spreadsheet that are unlocked.

We have a large (4,000+ rows) excel worksheet from a prior employee that I
would like to be able to use, but it is password protected and no one has the
password. Is there a way to copy or save it as a different file that will
not copy the password protection? It would save me a couple days of work if
it is possible.
Thanks

I have found similar posts on the forum, but nothing without use of a userform.
I have the following code:
Code:
This works, but I want to hide the text as it is entered.
Is there a way I can enter this as a property? i.e. inputbox.text.property = ... or something?? I've tried what seems intuitive, but nothing works.
Help!
I have the following code:
Code:
Sub Development()
Pass = InputBox("Please enter development password", "Password")
If Pass = "XYZ" Then
UnhideAll
Else: MsgBox ("Password incorrect, please try again")

Corporate edict.
I have a worksheet that is locked and protected now, except for cells in a certain collumn. I have named the cells in that column "MS96A".
If a user enters a date in a cell or range of cells anywhere in the column, the changed cells also need to be locked and protected (Once they enter a date, it is not allowed EVER to be changed again. Corporate requirement! *Shrug*).
What I am looking for is this. If the user selects that cell again, they will get the usual pop-up message, "The cell or chart that you are trying to change is protected..."
I think I am close, but I am getting an "End If without block If" error on the If Clause.
Sub Worksheet_Change(ByVal Target As Excel.Range)
Dim MRange As Range
Set MRange = Range("MS96A")
' If Not Intersect(Target, MRange) Is Nothing Then For Each cell In MRange Sheets("Sheet1").Unprotect Password:="temp"
cell.Interior.ColorIndex = 3
cell.Font.Color = vbBlack
Selection.Locked = True
Selection.FormulaHidden = False
Next cell
ActiveSheet.Protect Password:="temp", _
DrawingObjects:=False, _
Contents:=True, _
Scenarios:=False
ActiveSheet.EnableSelection = xlUnlockedCells
End Sub

Hey guys,
I have an excel file that is password protected. I have opened it as read-only.. Is there any way to unlock it & do it modifiable when I already opened it as read only (of course without having to close it & re-open it and enter password lol)
Thanks,

I'm trying to use VBA to go to a website that requires a User Name, Password, and a Submit Button.
So far I can get everything to work besides the Submit part. The code runs without errors, but doesn't actually "hit" the submit button on the webpage.
For posting, I removed my actual user name and password and and used the generic " User Name " and " Password " highlighted in blue.
I highlighted another section in green that I took from a previous post hoping it would solve my problem. The link is: http://www.mrexcel.com/forum/showthr...xplorer+submit

Do While .busy: DoEvents: Loop
Do While .ReadyState 4: DoEvents: Loop
.document.getelementbyid("fUserName").Value = " UserName "

Is there a way to lets say go to www.gmail.com and automatically have VBA fill in the user name and password ? I am trying to automate login for my co workers to a certain site. Just havent been able to find out how. PLZ HELP !!
I have a Workbook with 2 sheets, the first one is the data entry and the second one contains all the calculations and confidential info.
I have one staff member that does the data entry but I don't want them to see the 2nd sheet. I know I can hide the sheet then protect the entire workbook which does work, but is there an easier way so that the second person doesn't have to keep hiding/unhiding the 2nd sheet?
It would be perfect if when you tried to click on Sheet2, it asked for a password.
Cheers

Thnx for your help man. Now I have another situation.
I have the following:
1. Login form containing username and password fields.
2. Data entry form
I want to do the following:
1. Coding for username and password fields, which, If the login is successful, takes me to DATA Entry Form, Otherwise shows message "Invalid Login".
Thanks in anticipation.

Hello,
i've got the following problem:
I want users to double-click on a row on a protected sheet and then do some code based on the row-number of the clicked cell. I've protected the sheet because it contains a lot of formula's.
When a user double-clicks a row it triggers the code through the Workbook_SheetBeforeDoubleClick event.
After the code is executed Excel shows a message that the cell that was clicked was protected etc etc.
How can I prevent this message from popping up?
I've already tried
Code:
but that didn't work
Thanks

I have protected a worksheet as it has several formulae on that I do not wat anyone else to mistakingly delete. I then have spent time on setting up a sheet to track changes (just in case this has any bearing on the problem). This is the only thing that I think I have changed since protecting this morning and now I cannot unprotect the sheet. I have not protected the workbook and the unprotect sheet function is now greyed out.
Any ideas?

I saw two threads in this forum that asked this question, with no good answer. I am posting this solution for anybody still struggling with this.
The question:
How can you prevent a cell's contents from overflowing into the next cell?
Of course, you can make the column wider or turn on text wrapping, but you might not want to. Each of those solutions can mess up the layout of your sheet. You may just want to truncate the value.
Some people have suggested putting a space in the next cell. This is unnecessary, a pain in the but, and will mess up any ISBLANK type formulas, among other things.
The solution:
Select the cells in question and turn on text wrapping (Format>Cells>Alignment>Wrap Text).
Now select the row(s) in question and manually set the row height, by right clicking the row number and selecting "Row Height". Check the height of an adjacent row for a good value.
Your cells will now not spill over either horizontally or vertically. They will simply truncate anything that doesn't fit.
Be careful now, because parts of your data may be hidden. This can cause its own set of problems if one or two digits are neatly hidden away. Think ahead if other people might be using this sheet, and not be expecting to have some data hidden.

This is probably an easy question for most of you, but it's killing me. I tried searching before I posted this, but the suggestions given didn't seem to work for me.
I need to look up data from a cell on one Excel sheet, compare it to a list on a 2nd sheet and when they equal, take a value from a different column on the 2nd sheet and drop it back on the 1st sheet. Since that's a horrible explanation, let me try explaining it this way:
Sheet 1
Column A has a long list of code type 1s
Column E has a long list of code type 2s
Sheet 2
Cell C2 has code 1
Cell E2 needs code 2
I know it should take an index/match function, but nothing I try is working. What I'm trying is the following formula in Cell E2 of sheet 2:
=INDEX('Sheet 1'!A:A,MATCH(C2,'Sheet 1"!E:E,0),5)
But all I get is no result. What's driving me bonkers is that if I copy everything over to a single sheet, that formula works fine.

Hi everyone....this is my first post here ....and not my last I believe!
My question I believe is easily solvable for you cracks of excel.
I have a worksheet with a list of rows (item#, date, price, etc). In the last column of this list I can put an x for some of the items.
On another worksheet or sheet, I need to autoamtically have a list of the items in the first list above, that have an X in the last columns.
I created an example on a worksheet attached just for you to understand.
I apreciate all the help I can get.
Thank you so much.

I have a sheet with a list of names on and I've noticed that when I use ctrl+F to use the find function, even when I know i have entered the correct name it still will not work. I have identifed times when I know the name is there on the sheet, but the find function says "Excel cannot find the data you are searching for"

Hi All,
Random question i have a large Excel Workbook (which is protected) and has over five sheets on it - however one sheet has randomly decided not to scroll... yes i know sounds random! If i use the cursor and down arrows the selection just disappears off the screen.
The page will scroll if i filter by one field, but not if i select (All) for all filters.
All other worksheets scroll fine.
Any suggestions?
Thanks in advance.
Cheers Kaite

Some time ago I created a spreadsheet and greyed out the areas that weren't needed. Now I need to expand the spreadsheet and use more columns. Trouble is I've forgotten how to unhide those columns. I didn't write any macros and usings the right-click unhide method is proven futile. The sheet isn't protected which is puzzling since I can't get the mouse to even highlight any of the greyed out areas.
Any suggestions would be fantastic!
thanks

How do I grant only specific people to be able to open, view, edit an excel file? I don't want anybody else besides these two people to be able to even open the file, so I'm not talking about password protecting to prohibit editing a file. I would assume I need to go to the properties, security settings but I'm not sure?
I have an Excel workbook that was created by a former coworker. It includes a macro that, among other things, displays a message box about the 2008 file. The macro runs as soon as the file is opened. I'd like to access that macro to correct the date to 2011 and see what else, if anything, it's doing for me (it doesn't appear to do much). I can find references to creating macros to hide and unhide rows/columns and I found ways to delete all macros in a workbook, but I cannot find anything about unhiding a macro without knowing its name.
Does anyone know of a way to unhide this macro?
Thanks!

Hi! I am new to Excel and I am creating fillable forms in excel which are protected so that users canonly input data in certain cells. I am using Excel 2003. The users told me that they do not want text to go beyond the edge of the page when they are inputting data. They also want the words to wrap when they reach the end of the sentence. I am also using check boxes(yes/no) and Ifind it difficult to make the adjacent cells fillable only Thanks for your help and correct me if I am wrong as I am new to this board.
