This sample code shows you how to register your visual basic program on the windows startup registry. First of all, copy and past all below code to a module.
Option Explicit
Public Declare Function RegCloseKey Lib "advapi32.dll" (ByVal Hkey As Long) As Long
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 RegDeleteKey Lib "advapi32.dll" Alias "RegDeleteKeyA" (ByVal Hkey As Long, ByVal lpSubKey As String) As Long
Public Declare Function RegDeleteValue Lib "advapi32.dll" Alias "RegDeleteValueA" (ByVal Hkey As Long, ByVal lpValueName As String) As Long
Public Declare Function RegOpenKey Lib "advapi32.dll" Alias "RegOpenKeyA" (ByVal Hkey As Long, ByVal lpSubKey As String, phkResult As Long) As Long
Public Declare Function RegQueryValueEx Lib "advapi32.dll" Alias "RegQueryValueExA" (ByVal Hkey As Long, ByVal lpValueName As String, ByVal lpReserved As Long, lpType As Long, lpData As Any, lpcbData 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
Public Const REG_SZ = 1 ' Unicode nul terminated String
Public Const REG_DWORD = 4 ' 32-bit number
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
Public Const ERROR_SUCCESS = 0&
Public Sub SaveString(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
Next, to make the entry in the registry, use code like this (this only really needs to be done once, but could be called in Form_Load each time your app starts):
SaveString(HKEY_LOCAL_MACHINE, "SOFTWARE\Microsoft\Windows\CurrentVersion\Run", _
App.ExeName, App.Path & "\" & App.ExeName & ".exe")
Hope this code will make you programming life easy...:D
