Yes. U can do that. If u want to manipulate cursor alone ie to hide it u can use ShowCursor API call. If u want to disable the right clikc event or something like that use this:

---------Module COde-----

Declare Function CallWindowProc Lib "user32" Alias "CallWindowProcA" (ByVal lpPrevWndFunc As Long, ByVal hWnd As Long, ByVal Msg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA" (ByVal hWnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long
Public Const GWL_WNDPROC = -4
Public Const WM_RBUTTONUP = &H205
Public lpPrevWndProc As Long
Private lngHWnd As Long
Public Sub Hook(hWnd As Long)
lngHWnd = hWnd
lpPrevWndProc = SetWindowLong(lngHWnd, GWL_WNDPROC, _
AddressOf WindowProc)
End Sub
Public Sub UnHook()
Dim lngReturnValue As Long
lngReturnValue = SetWindowLong(lngHWnd, GWL_WNDPROC, lpPrevWndProc)
End Sub
Function WindowProc(ByVal hw As Long, _
ByVal uMsg As Long, _
ByVal wParam As Long, _
ByVal lParam As Long) As Long
Select Case uMsg
Case WM_RBUTTONUP
'Do nothing
'Or popup you own menu
Case Else
WindowProc = CallWindowProc(lpPrevWndProc, hw, uMsg, wParam, lParam)
End Select
End Function
---------

Form Code
---------
Private Sub Form_Load()
Call Hook(Text1.hWnd)
End Sub
Private Sub Form_Unload(Cancel As Integer)
Call UnHook
End Sub
-----------


This would give u an idea.

Hi dekoay,

What about hide the cursor ?

'put in the module
Declare Function ShowCursor& Lib "user32" _
    (ByVal bShow As Long)
    'Add this code to Command1.


Private Sub Command1_Click()
    ShowCursor (bShow = True)
End Sub

Private Sub Command2_Click()
    ShowCursor (bShow = False)
End Sub

hope this helps

what is the idea?  theres no need to subclass those objects since they have a direct property to prevent the user from editing them.

Hello wzm,
Perhaps I should u r wrong. The idea for disabling mouse is not allow user to use them.Instead, they use tab key to move from field to field for editing.
