Placing a form permantly in the back ground.

How can i place a form permantly in the back ground but still let the user use it? Any help is great!!

You mean that it should do processing in Background, and its invisible? Thats is what you mean?

No i'm trying to create a program that runs on the desktop behind all other apps and still lets the user click on buttons.

But if its behind all the other apps, how will your use be able to see it to click on it?

Behind all other apps.. How to click?
If its behind all application, how user will be able to click it?

Ok i just need to make a 'Desktop' app and app that can replace the windows desktop!

You want to re-write explorer? A new windows shell? Okley dokely.... this is no mean feat, but there are examples on www.pscode.com:

A little searching goes a long way. :)

Use the same api call when setting your form on top.

Declare Function SetWindowPos Lib "user32" (ByVal hwnd As Long, _
ByVal hWndInsertAfter As Long, ByVal x As Long, ByVal y As Long, _
ByVal cx As Long, ByVal cy As Long, ByVal wFlags As Long) As Long

Public Const HWND_BOTTOM = 1
Public Const HWND_TOP = 0
Public Const HWND_TOPMOST = -1
Public Const HWND_NOTOPMOST = -2

Public Const SWP_FRAMECHANGED = &H20
Public Const SWP_HIDEWINDOW = &H80
Public Const SWP_NOACTIVATE = &H10
Public Const SWP_NOCOPYBITS = &H100
Public Const SWP_NOMOVE = &H2
Public Const SWP_NOREDRAW = &H8
Public Const SWP_NOSIZE = &H1
Public Const SWP_NOZORDER = &H4
Public Const SWP_SHOWWINDOW = &H40

Public Enum WindowPos
OnTop = 1
Normal = 2
OnBottom = 3
End Enum

Public Sub FormPos(hwnd As Long, wPos As WindowPos)
Select Case wPos
Case WindowPos.OnTop
SetWindowPos hwnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE Or SWP_NOSIZE
Case WindowPos.Normal
SetWindowPos hwnd, HWND_NOTOPMOST, 0, 0, 0, 0, SWP_NOMOVE Or SWP_NOSIZE
Case WindowPos.OnBottom
SetWindowPos hwnd, HWND_BOTTOM, 0, 0, 0, 0, SWP_NOMOVE Or SWP_NOSIZE
End Select
End Sub

Thank you!!!!!!!!!!!!!!:D :D :D :D :D

There is somethingmissing in the 'Select Case' Stat!

The forum filters out the word p-o-s (without the hyphons) because it can be used in a derogatory manner. The last part should look like this:
Public Sub FormPos(hwnd As Long, Win As WindowPos)
Select Case Win
Case WindowPos.OnTop
SetWindowPos hwnd, HWND_TOPMOST, 0, 0, 0, 0, SWP_NOMOVE Or SWP_NOSIZE
Case WindowPos.Normal
SetWindowPos hwnd, HWND_NOTOPMOST, 0, 0, 0, 0, SWP_NOMOVE Or SWP_NOSIZE
Case WindowPos.OnBottom
SetWindowPos hwnd, HWND_BOTTOM, 0, 0, 0, 0, SWP_NOMOVE Or SWP_NOSIZE
End Select
End Sub

Thanks! I have started my Desktop app.
