bott = Boot and it's a password program.

To make your program boot when windows does, add a Registry entry to the following path.

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run.

The value should be the name of your App and the Data should be the path to it. This will make it boot when Windows does. To stop it, simply remove it.

does anyone getone im talking about. like if window is not shut down right it start that one thing . just like that.

how would i do that.

is your brother old enough and pc smart enough to get into your startup folder..cause if he is not you could just put a little pgm in the startup folder and it will start evertime windows starts...if you want one I have a little beauty I use at work and I can copy it here cause it is quite small...you'll just have to add a button and cut and past some code...

Hey Megatron
How can I edit the registry with VB to make that entry?

[wasiq]

u can add some code in the form_unload area that writes a value to the registry, and on the next startup see it the form was unloaded correctly = true or otherwise = false. got my point?

Zaphod64831: Try this:

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

Usage

'Save a Value to the Registry
savestring HKEY_CURRENT_USER, "Software\Myapp", "Testing", "Hello"

'Get a value from the Registry
Retval = GetString(HKEY_CURRENT_USER, "Software\Myapp", "Testing")
