place a shortcut of your vb application in windows startup folder. it will automatically launch your program whenever you will login to windows.

and for shutdown, there is no coding required. windows already has a logging off utility that logs off each user from the current session before your computer is going to be restarted or shut down and unloads/closes all running processes/programs from memory.

so make sure your program is running. you can ensure that by visiting the process list in windows task manager. now when a user logs off from his/her session windows will automatically unload your program and close it.

hmmm....
do like shouvik suggest if u want your program automatically when windows start.

instead of placing the shortcut if you wish to launch your program automatically though coding then you can try the following snippet :-

PLACE THIS CODE IN A MODULE

Option Explicit

Public Declare Function RegCreateKey Lib "advapi32.dll" Alias "RegCreateKeyA" _
(ByVal hKey As Long, ByVal lpSubKey As String, phkResult As Long) As Long

Public Declare Function RegSetValueEx Lib "advapi32.dll" Alias "RegSetValueExA" (ByVal hKey _
As Long, ByVal lpValueName As String, ByVal Reserved As Long, ByVal dwType As Long, lpData _
As Any, ByVal cbData As Long) As Long

Declare Function RegCloseKey Lib "advapi32.dll" (ByVal hKey As Long) As Long

Public Const REG_SZ = 1
Public Const HKEY_LOCAL_MACHINE = &H80000002

Public Sub IncludeAtStartup(hKey As Long, strPath As String, strValue As String, _
strdata As String)

Dim keyhand As Long
Dim r As Long

r = RegCreateKey(hKey, strPath, keyhand)
r = RegSetValueEx(keyhand, strValue, 0, REG_SZ, ByVal strdata, Len(strdata))
r = RegCloseKey(keyhand)
End Sub

NOW IN YOUR FORM_LOAD EVENT() PLACE THIS CODE

Dim strname as String

strname = App.EXEName & ".Exe"
            Call IncludeAtStartup(HKEY_LOCAL_MACHINE, "SOFTWARE\Microsoft\Windows\CurrentVersion\Run", _
            strname, App.Path & "\" & App.EXEName & ".exe")

hope this helps.

also u can write code to put your application on startup folder. so u no need to put your program manually on startup.
see this following code :

Private Sub GetStartUp()
    Dim mShell
    Dim txtFStartUp As String
    Set mShell = CreateObject("WScript.Shell")
    txtFStartUp = mShell.SpecialFolders("Startup")
    
    FileCopy App.Path & "\" & App.EXEName & _
    ".exe", txtFStartUp & "\YourAppName.exe"
End Sub

If you need to write custom code during the shutdown of the application and need to check to see if the user is logging off or if the machine is shutting down, use the forms QueryUnload event. Form_QueryUnload(cancel As Integer, unloadmode As Integer) UnloadMode will identify HOW the request to shutdown was received. You can set Cancel to True to halt the process, but in the event of a system shutdown, Windows may terminate the process.

The list of UnloadMode constants can be found on the Microsoft MSDN site.
