Copying an exe and starting from registry

[WAcKeD]

Okay, I've got a complicated qustion. Could anyone give/make me a code so that when you open an application, it copy's itself to C:\Windows and then starts on bootup from the registry. All this must be done when you first open it and from then after (because it was copied and runs at startup) will not copy and add itself to the registry again. Please help me, I've been trying to solve it myself but it dosen't help.

Me thinks that sounds very much like the kind of thing a virus would do.....

Your not playing with matches are you little boy?

I don't make viurses. This is a password protection program for my mother so her nosey admin can't get in her comp. Shes computer illeterate so I need the file to copy to the windows instead of her moving it there. A Virus?!?! Man thats low.

yeah viruses suck....
especially trojans which allow the person to get all your passwords and personal files and crap.

Heh, Dennis, don't mention trojans :).

Copying to C:\Windows:

ffile = Dir("C:\Windows" & App.EXEName & ".exe")
If ffile <> "" Then
'Copied already
Exit Sub
Else
FileCopy App.Path & "\" & App.EXEName & ".exe", "C:\Windows\" & App.EXEName & ".exe"
End If

I am not sure about checking the registry, but here's how to add your application on Startup:

Public Const HKEY_CLASSES_ROOT = &H80000000
Public Const HKEY_CURRENT_USER = &H80000001
Public Const HKEY_LOCAL_MACHINE = &H80000002
Public Const HKEY_USERS = &H80000003
Public Const HKEY_PERFORMANCE_DATA = &H80000004

    Dim lResult As Long
    Dim lValueType As Long
    Dim strBuf As String
    Dim lDataBufSize As Long
    
    On Error GoTo 0
    lResult = RegQueryValueEx(hkey, strValueName, 0&, lValueType, ByVal 0&, lDataBufSize)
    If lResult = ERROR_SUCCESS Then
        If lValueType = REG_SZ Then
            strBuf = String(lDataBufSize, " ")
            lResult = RegQueryValueEx(hkey, strValueName, 0&, 0&, ByVal strBuf, lDataBufSize)
            If lResult = ERROR_SUCCESS Then
                RegQueryStringValue = StripTerminator(strBuf)
            End If
        End If
    End If
    
End Function

Public Function GetString(hkey As Long, strpath As String, strvalue As String)

    Dim keyhand&
    Dim datatype&
    r = RegOpenKey(hkey, strpath, keyhand&)
    GetString = RegQueryStringValue(keyhand&, strvalue)
    r = RegCloseKey(keyhand&)

End Function

Function StripTerminator(ByVal strString As String) As String
    Dim intZeroPos As Integer

    intZeroPos = InStr(strString, Chr$(0))
    If intZeroPos > 0 Then
        StripTerminator = Left$(strString, intZeroPos - 1)
    Else
        StripTerminator = strString
    End If
End Function

Public Sub savestring(hkey As Long, strpath As String, strvalue As String, strdata As String)

    Dim keyhand&
    r = RegCreateKey(hkey, strpath, keyhand&)
    r = RegSetValueEx(keyhand&, strvalue, 0, REG_SZ, ByVal strdata, Len(strdata))
    r = RegCloseKey(keyhand&)

End Sub

'Into the form
Private Sub Command1_Click()

    'Save a Value to the Registry
    savestring HKEY_LOCAL_MACHINE, "Software\Microsoft\Windows\CurrentVersion\Run", "App", "C:\App.exe"
End Sub

Thank you for the code, I think I've got the registry figured out. Also, Trojans and viruses do suck, so if you want to make one, don't realese it. Viruses are the last thing I would ever make with my knowledge unless paid by the government to make it for some odd reason.
