Mouse inactivation

[avsb]

please help !

When a user enters data into a text box, on "enter"Key being pressed, calculations are carried out. How do we stop the user from being able to use a mouse button to go to another text box without first hitting enter, and therefore bypassing the calculation which will need to be done with the data he has just entered into the text field.

Your help would be greatly appreciated !!

Hi
Can't u just call the calculation subroutine from the Validate event of the textbox?

I think this will do it:

Private Type RECT
    left As Long
    top As Long
    right As Long
    bottom As Long
End Type
Private Type POINT
    x As Long
    y As Long
End Type
Private Declare Sub ClipCursor Lib "user32" (lpRect As Any)
Private Declare Sub GetClientRect Lib "user32" (ByVal hWnd As Long, lpRect As RECT)
Private Declare Sub ClientToScreen Lib "user32" (ByVal hWnd As Long, lpPoint As POINT)
Private Declare Sub OffsetRect Lib "user32" (lpRect As RECT, ByVal x As Long, ByVal y As Long)


Private Sub Form_Load()
    Command1.Caption = "Limit Cursor Movement"
    Command2.Caption = "Release Limit"
    Command3.Caption = "No mouse input!"
End Sub
Private Sub Command1_Click()
    'Limits the Cursor movement to within the form.
    Dim Client    As RECT
    Dim upperleft As POINT
    
    'Get information about our wndow
    GetClientRect Me.hWnd, Client
    upperleft.x = Client.left
    upperleft.y = Client.top
    'Convert window coördinates to screen coördinates
    ClientToScreen Me.hWnd, upperleft
    'move our rectangle
    OffsetRect Client, upperleft.x, upperleft.y
    'limit the cursor movement
    
    ClipCursor Client
End Sub
Private Sub Command2_Click()
    'Releases the cursor limits
    ClipCursor ByVal 0&
End Sub

Private Sub Command3_Click()
    'Disables the mouse input. Use the arrow keys or Tab instead...
    Dim Client As RECT
    
    Client.left = 0
    Client.top = 0
    Client.right = 0
    Client.bottom = 0
    
    ClipCursor Client
End Sub

Private Sub Form_Unload(Cancel As Integer)
    'Releases the cursor limits
    ClipCursor ByVal 0&
End Sub
