'enter below statement for each worksheet To enable user interface protection for specified worksheets only or if the worksheets have different passwords, set the UserInterfaceOnly argument as true in the Workbook_Open event, as follows. Ws.Protect Password:=" abc", UserInterFaceOnly:=True

Please note that workbook events code must be placed in the code module for the ThisWorkbook object. If all worksheets use the same password, then set the UserInterfaceOnly argument as true in the Workbook_Open event, as follows. Using the UserInterfaceOnly argument, in the Workbook_Open event: Sheet1.Protect Password:=" abc", UserInterFaceOnly:=True Using the UserInterfaceOnly argument, in a worksheet: You can also use the UserInterfaceOnly argument in a worksheet, at the beginning of the macro, to enable the user interface protection each time the macro is run. To re-enable the user interface protection after the workbook is opened, you can use the UserInterfaceOnly argument in the Workbook_Open Event wherein it gets enabled in all or the specified worksheets, each time the workbook is opened. To re-enable the user interface protection after the workbook is opened, you must again apply the Protect method with UserInterfaceOnly set to True. It may be noted that if you apply the Protect method with the UserInterfaceOnly argument set to True to a worksheet and then save the workbook, the entire worksheet (not just the interface) will be fully protected when you reopen the workbook. If this argument is omitted, protection applies both to macros and to the user interface. Setting the UserInterfaceOnly argument to True means that the worksheet protection applies only to the user interface and does not apply to macros and this will allow Excel to run all macros in the worksheet. UserInterFaceOnly argument is an optional argument in the Protect method and its default is False. The On Error GoTo statement traps all errors, regardless of the exception class.Ī better way to run macros in a protected worksheet would be to use the UserInterfaceOnly argument in the Protect method, by setting the UserInterfaceOnly argument to True, in the manner: "Sheet1.Protect Password:= " abc ", UserInterFaceOnly:= True". On Error GoTo Line: Enables the error-handling routine that starts at the specified Line. It disables enabled error handler in the current procedure and resets it to Nothing. The On Error GoTo 0 statement turns off error trapping. On Error Resume Next: Specifies that when a run-time error occurs, control goes to the statement immediately following the statement where the error occurred, and execution continues from that point.

'Turn off error trapping and re-allow run time errors 'this code will run, because on encountering the above error, the code continues execution from next statement, and worksheet remains protected. 'this code will not run, because on encountering the above error, you go directly to the Error Handler The worksheet will remain unprotected in the absence of an Error Handler. 'this code will give a run-time error, because of division by zero. 'this code will run irrespective of an error or Error Handler 'Enable error-handling routine for any run-time error To overcome the first shortcoming wherein the worksheet remains unprotected upon the code encountering an error, you can use an ErrorHandler, as shown below: unprotect & protect statements) repeatedly in each macro.

However, this method has some shortcomings: (i) if the code encounters an error or gets interrupted, your worksheet will remain unprotected (ii) your worksheet protection password will be displayed in the vba code (vba projects usually protect worksheet with vba code instead of directly from worksheet menus), unless you protect your VBAProject (in the VB Editor code window) to disallow access or viewing of your code and (iii) you will need to enter this code (ie. One option is to unprotect the worksheet, run the code / macro, and then protect it again, as shown below: If you run macros on a protected worksheet which attempt to make changes in the worksheet, you will encounter an error, "Run-time error '1004': Application-defined or object-defined error".
