Prevent A User From Opening Another Workbook
Feb 12, 2009
How can I prevent a user from opening another workbook in an Excel session "from the outside"?
I'm fairly new to VB. I'm developing (in VB 2003) a simple but SECURE Excel environment which will allow a user to update a hidden Master_Records workbook. I need to keep the user's Excel session secure...for example, I've disabled all Excel Toolbars and Command Buttons, effectively preventing the user from doing anything except filling in some cell values and clicking on a few custom buttons in the worksheet. But how can I prevent the user from opening another workbook into the active session from his desktop and introducing some malicious code into the session via that route?
One respondent in another forum (the only one, in fact) suggested that I look into "instantiating workbook level events" so that I can detect when other workbooks are open. I'm not sure what that means, is there someone here who could give me some guidance into that solution?

I am relying on macros for a lot of functionality and security.
Is there a way to stop a spreadsheet from being opened/accessed if a user disables macros at the security prompt?

I am trying to have an operation run when opening the Workbook. The UserForm opens fine, but I get an error when the GoButton_Click sub runs. The error file is not very comprehensive.
The user is promoted to 'Delete' or 'Cancel' before the sheet is deleted. I do want to select 'Delete' for the user, but I'm not sure how to do this.
The error mentioned occurs after the user selects 'Delete'. The error is:
Run-time error '-2147417848 (80010108)':
Automation error
The object envoked has disconnected from its clients.
VB:
Option Explicit
Private Sub UserForm_Initialize()
Me.Choices.List = Array("Choice 1", "Choice 2")
End Sub
Private Sub GoButton_Click()
If Templates = "Choice 1" Then
[Code]....

I have a user form that has a combo box "City" two text boxes one called "Flight" and the other "Date". What I'm trying to do is to prevent the user from saving the data input from the user form if any of those three fields is left blank. The code that I have so far checks all of the required fields, if any are left blank a message notifys which field(s) is left blank and return the focus back to that field. But the rest of code also fires.
What I really need is either to stop the code if any fields are blank and return the focus back to the blank field, the user completes the field(s) and clicks the save again, or better yet, pause the code until all the required fields are completed and then complete the save. (There is actually another 200+ lines of code in this sub, but I deleted it to keep the post a little shorter.)

I know how I can protect worksheet or a group of cells, but I can not prevent any one to damage it by (open with) WORDPAD to clean or damage it then to cancel this protection!

I currently have a spreadsheet that my deparment use at work. Its just a full time equivallent sheet, nothing fancy. However I added code onto it to prevent users opening it as I was updating it.
However I went to open it and It wouldnt open. It wouldn't recognise me as being the exception. Its just a code on the workbook open that says if user is "slb090" (which is me) then do nothing, else msgbox and just a quickie sayign come back later".
I have attached the spreadsheet, in the hope someone can open this for me and remove the message so I can open it!

the code always opens a new instance of Outlook even though one may already be open. If left unchecked I may have like 30 instances open if I leave the computer for a few hours. So I was wondering is there some snippet of code I can add in here to check if excel is open first and if so do not open a new instance?
Code:
Dim OutApp As Object
Dim OutMail As Object
Set OutApp = CreateObject("Outlook.Application")
Set OutMail = OutApp.CreateItem(0)
On Error Resume Next
' Change the mail address and subject in the macro before you run it.
With OutMail
.To = "xxxx@live.com"

I have a need to open a file from my companies intranet. My current method was to open said file via the method that the recorder gave me. However, I would like ot be able to open a said file without having to start open another workbook.
This is the path:
[url]
So the command is this:
Workbooks.Open [url]
Links are not actual links
So what I need to know. Is how can I open this file without opening a workbook. I haven't been able to use the VB "Open Statement" to open a file and I don't believe that I've been successfull using the Filesystem object either.

I have a simple spreadsheet which requires a date (mm/dd/yy) in Column A. Columns B-F use formulas to break this date down into the month, quarter, year, etc. Users frequently need to add new rows at the top of the sheet just below the column headers.
To be sure the formulas in Columns B-F are included when adding new rows, I put together a simple macro which copies the top ten rows, inserts them at the top of the sheet, and then clears existing data from the new rows (keeping formulas intact).
I put a button on the sheet to run this macro. However, sometimes users insert new rows without using the macro. This results in no data in Columns B-F for these new rows because the formulas weren’t copied.
How can I prevent this from happening? If I protect the sheet and prevent users from inserting new rows, the macro won’t run. Is there something I can add to the macro that will allow it to run properly while the sheet is protected? Below is the macro code.
Private Sub CommandButton1_Click()
Rows("3:12").Select
Selection.Copy
Rows("3:3").Select
Selection.Insert Shift:=xlDown
Range("A3:A12").Select
Application.CutCopyMode = False
Selection.ClearContents
Range("G3:K12").Select
Application.CutCopyMode = False
Selection.ClearContents
Range("A12").Select
End Sub

I have tables on a spreadsheet and userforms created. Is there anyway to prevent users from just typing on the worksheet so they will have to use the userform?

I have an Excel sheet that displays 50 rows and 20 columns when it is opened the first time. These rows and columns are the only ones that I want the user to be able to see. The user shouldn't be able to navigate the sheet by using the scroll bars or the wheel on the mouse. I have of course already removed the scroll bars but I don't know how to handle the scroll wheel problem.

I am using following code to effect a change which works fine:
Code:
Private Sub Worksheet_Change(ByVal Target As Range)
Sheets("Closed Flts").Unprotect "abcd"
Sheets("Faults").Unprotect "abcd"
[Code].....
But when the sheet is unprotected to effect this change the formula in cells ( row I and L) are visible to user and can delete them. Or they can even delete the cell itself or modify formula.
The formule in Row I is
Code:
=IF(A12="","",IF(G12=1,A12,IF(G12=2,A12,IF(G12=3,A12+1,IF(G12=4,A12+5,IF(G12=5,A12+28,"priority?"))))))
And in Row L is
Code:
=IF(A13="","",IF(I13

I have this script below which I am trying to modify to pull information from each file in the folder and draw cell values from different sheets within the file. I have the script working prior to the modification but the difference was I was pulling all the different cell values from the same single sheet in the file.
I believe the issue I have (Excel reporting that file is already open and then eventually erroring out) is because the way I'm going about this is causing Excel to open the file multiple times without closing (my coding isn't the best) here -
Do While fn ""
On Error GoTo Handler:
Set ws = Workbooks.Open(myDir & fn).Sheets(7)
Set ws2 = Workbooks.Open(myDir & fn).Sheets(2)
Set ws3 = Workbooks.Open(myDir & fn).Sheets(3)
Set ws4 = Workbooks.Open(myDir & fn).Sheets(8)
Sheet4.Range("a" & Rows.Count).End(xlUp).Offset(1).Resize(, 6).Value = _
Array(ws4.Range("AI6").Value, ws.Range("ac4").Value, ws2.Range("ac4").Value, ws3.Range("ac4").Value, ws4.Range("ac4").Value, myDir & fn, fn & "-" & ws.Name)
Workbooks(fn).Close False
fn = Dir
Loop
I'm hoping there is a better way of pulling information from multiple sheets in the file that actually works as the above now I think it through is obviously not very clever.
A second issue I have is that whilst some people running this script don't have access to save to this network drive (so can not save changes), some users CAN. Is there a way I can force the script to open these files as Read Only or ensure that they are closed UN-saved - just to cover any mishaps??
Here is the full script -...................

Is it possible to write VBA code that will prevent a user from changing a cell's contents, depending on the cell's font color?
More specifically, I have a column of text in range B15:B64. Some of the cells will have a black font, others will be blue. Is it possible to lock the black font cells only, leaving the blue cells unlocked for users to change?

what I want. It relies on an input box asking the user to enter a part code, which when found creates a duplicate copy. However, if the user enters a part that doesn't exist I get a run-time error. Can anybody point me in the right direction so when a user enters an incorrect part they get a message telling them it doesn't exist.
Private Sub SortTest_Click()
Dim s As String
Dim r As Excel. Range
Range("A2").Activate
s = InputBox("Enter the number you wish to find")
If StrPtr(s) = 0 Then
MsgBox "You must enter an existing part number!"
Else
Set r = Cells.Find(What:=s, After:=ActiveCell, LookIn:=xlFormulas, _
LookAt:=xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext, _
MatchCase:=False, SearchFormat:=False)
Range(Cells(r.Row, "A"), Cells(r.Row, "AH")).Copy
Sheets("APL").Cells(r.Row, "A").Insert Shift:=xlDown
Application.CutCopyMode = False
Application.Goto Sheets("APL").Cells(r.Row, "H")
Selection.Offset(-1, -5).ClearContents
Selection.Offset(-1, 0).Select
End If
End Sub

I have a feeling the answer to this will be 'no' based on the searching I've done, but is it possible to allow formatting of rows/columns on a protected worksheet, yet prevent the user from unhiding some rows/columns I don't want them to see? I've allowed them to format rows/columns so they can "size" them to fit the text they enter, but that has opened up the ability for them to unhide columns. Using Shrink To Fit would be cumbersome due to the number of cells involved.

I am simply trying to write a macro or code that will set all the check box values to "False" each time I initiate the User form. So that the user form does not "carry over" check box values from the last time the User form was used.
However I had to make sure I cleared the value from the cell that each control is associated with.(the controlsource in the user form properties.)

I am using the below code (i have combined different bits of code which i found on these forums) to open a new workbook, copy all the data in it and paste it into Sheet2 in the active workbook . Also, i want the data to be pasted on the next empty row as there is already data in Sheet2. The data that is being copied and pasted has the same format and it is going to be repeated many times.
The problem i am having is that it is not offsetting the data to the next empty row - i think it is a simple change but i can't seem to get there :s
Also, the code is currently selecting all of the data from the workbook that i open - is there a way i can select all of the data, excluding the first row (the first row contains the headings which i already have in Sheet2 in the active workbook).

I have a spreadsheet that data gets exported to from a software program. There is information such as customer name, part number, inquiry number, etc that I'd like to use to develop a log of all my estimates I create for parts. I'd like excel to take the cells I select and insert them into certain cells in the other workbook and automatically save that workbook. This will create a log of all my estimates where I can then link the full estimate to the log. The information will have to go in the next available row. Is there any way I can accomplish this without having to open the other workbook and save the work book each time?

I'm wondering if it is possible to prevent a user saving a workbook. If opened as a read-only, excel throws up an option to save with an alternative name. I'm wondering if I can put some code in the Workbook_BeforeSave event that prevents saving of the document unless the application.username is myself.
