Make sure lostfocus/validate event triggers

In general when you have a textbox normally best to use the validate or lostfocus event to execute some code when the focus is lost on that textbox (so when editing the textbox is done execute the code)

This normally is fine when staying inside vb forms,
but when changing from the VB form to let say notepad or word external application, the focus stays on the VB form's textbox and no code is executed and i do want te code to be executes, so maybe i have to force a lostfocus event when de form is no more activated (i allso tried to use the form events deactive, lostfocus and no succes, they are not triggered)
Any idea's?

If your app does not require them to do something in notepad, etc., then you can use the ClipCursor API to limit the user to the form. Here's an example from the API Guide. It requires a form with two command buttons.

VB Code:

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()
    'KPD-Team 1999
    'URL: [url]http://www.allapi.net/[/url]
    'E-Mail: [email][email protected][/email]
    Command1.Caption = "Limit Cursor Movement"
    Command2.Caption = "Release Limit"
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 Form_Unload(Cancel As Integer)
    'Releases the cursor limits
    ClipCursor ByVal 0&
End Sub
