Protect created or saved file as encrypt documents with my user name only

[loveguy1977]

Dear, Sirs,

I would like to protect my files whenever I create or open then save any excel file in my computer (with user say loveguy1977 + other words say 123456) as encrypt documents and that macro should be only in my personal macro (not as a vba in each excel bez it is easy to hack vba password)

Meaning the password will be (loveguy1977123456)

So no body will be able to open my files if copied or sent to them by mistake at the same time when it opened in my computer (user loveguy1977) it won't ask me for the password bez automatically it will consider the password as my user name + other word which be programed in my personal macro.

But if it open in another user then it will ask for the password which is (loveguy1977123456).

Please help me in this, it will help me and others as well. I really i'm need for it

Thank you

It seems that is diffcult to do what I wish.

However, I got another idea from this excel file with some modification
http://www.ozgrid.com/FreeDownloads/PasswordBook.zip

in this file, there is a sheet called "Config" that contents all user name & password.
I would like to delete that sheet i.e. "Config" and keep two user names + password in the vba itself.

meaning, I hope you modify this code for UserForm1

[VBA]Option Explicit
Private Sub CancelButt_Click()
ThisWorkbook.Close SaveChanges:=False
End Sub
Private Sub CommandButton1_Click()
ThisWorkbook.Close SaveChanges:=False
End Sub
Private Sub OKButt_Click()
Dim iFoundPass As Integer
On Error Resume Next
With Sheets("Config").Range("UserNames")
iFoundPass = .Find(What:=UserNameTextBox, After:=.Cells(1, 1), LookIn:=xlValues, LookAt _
:=xlWhole, SearchOrder:=xlByRows, SearchDirection:=xlNext, MatchCase:= _
False).Row
End With
On Error GoTo 0
If iFoundPass = 0 Then
SomethingWrong
Exit Sub
End If
If Sheets("Config").Cells(iFoundPass, 2) <> PasswordTextBox Then
SomethingWrong
Exit Sub
End If
Sheets("Config").Range("LoggedInAs") = UserNameTextBox
Unload Me

End Sub
Private Sub PasswordTextBox_Change()
OKButt.Enabled = (UserNameTextBox.TextLength > 2 And _
PasswordTextBox.TextLength > 2)
End Sub

Private Sub UserForm_QueryClose(Cancel As Integer, CloseMode As Integer)
If CloseMode = 0 Then Cancel = True
End Sub
Private Sub UserNameTextBox_Change()
OKButt.Enabled = (UserNameTextBox.TextLength > 2 And _
PasswordTextBox.TextLength > 2)
End Sub
Private Sub SomethingWrong()
MsgBox "Incorrect Username or Password.", vbCritical + vbInformation, "OzGrid.com"
End Sub[/VBA]



VBA in ThisWorkbook, I modified it to become as follow:

[VBA]Option Explicit
Private Sub Workbook_Open()
Dim objNet As Object
Dim i As Integer
On Error Resume Next
Set objNet = CreateObject("WScript.NetWork")


'To select the first sheet
For i = 1 To Worksheets.Count
If Sheets(i).Visible Then
Sheets(i).Select
Exit For
End If
Next i


If objNet.UserName <> "loveguy1977" Then
Set objNet = Nothing
Sheets("Config").Visible = xlVeryHidden
Application.EnableCancelKey = xlDisabled
UserForm1.Show
End If
Set objNet = Nothing
End Sub[/VBA]


Then I will protect each excel file's VBA with password.


Thank you very much
