How to disable the minimize, maximize & close buttons on a form??

Disable the close button from a form
Disable the Close button on any form in your project with this handy code snippet!

First of all, you will need to add a module to your project. (Project->Add Module).

Into this module, paste the following code:


Public Declare Function SetWindowPos Lib "user32.dll" (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 MF_BYPOSITION = &H400&

Public Declare Function RemoveMenu Lib "User32" (ByVal hMenu As Long, _
ByVal nPosition As Long, ByVal wFlags As Long) As Long

Public Declare Function GetSystemMenu Lib "User32" (ByVal hwnd As Long, _
ByVal bRevert As Long) As Long
Public Sub DisableClose(hWnd As Long)
Dim hMenu As Long
hMenu = GetSystemMenu(hWnd, 0)
RemoveMenu hMenu, 6, MF_BYPOSITION
RemoveMenu hMenu, 5, MF_BYPOSITION
End Sub 

Then, to disable the Close button on a form, use 
DisableClose(form.hWnd)

e.g. 
DisableClose(Me.hWnd)
will disable the close button from the current form.
