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

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

Code:

---

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 in ThisWorkbook, I modified it to become as follow:

Code:

---

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

---

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


Thank you very much
