Change every windows caption to "hello world"

Im just wondering how I would be able to change every windows caption running in windows except WINDOWS EXPLORER to "hello world!"

I also would like to learn the Mousemove effect.


thanks,

Code:

---

Declare Function GetCursorPos Lib "user32" (lpPoint As POINTAPI) As Long
Declare Function SetCursorPos Lib "user32" (ByVal X As Long, ByVal Y As Long) As Long

Type POINTAPI
        X As Long
        Y As Long
End Type

Property Get cursorX() As Integer
Dim pnt As POINTAPI
    temp = GetCursorPos(pnt)
    cursorX = pnt.X
End Property
Property Let cursorX(newvalue%)
    temp = SetCursorPos(newvalue, cursorY)
End Property

Property Get cursorY() As Integer
Dim pnt As POINTAPI
    temp = GetCursorPos(pnt)
    cursorY = pnt.Y
End Property
Property Let cursorY(newvalue%)
    temp = SetCursorPos(cursorX, newvalue)
End Property

---

With this in a module you can use cursorX and cursorY properties for setting and getting mouse position

put this in a module:

Code:

---

Private Declare Function EnumWindows Lib "user32" (ByVal lpEnumFunc As Long, ByVal lParam As Long) As Long
Private handles&(), counter&

Private Function EnmWinProc(ByVal hWnd As Long, ByVal lParam As Long) As Long
    Dim sCaption As String * 255
    ReDim Preserve handles(counter)
    handles(counter) = hWnd
    counter = counter + 1
    EnumWindowsProc = hWnd
End Function
Public Function GetWindows()
    ReDim handles(0)
    counter = 0
    Call EnumWindows(AddressOf EnmWinProc, 0&)
    ListWindows = handles
End Function

---

And in the file you want to change all captions of all windows:

Code:

---

'In declarations
Private Declare Function SetWindowText Lib "user32" Alias "SetWindowTextA" (ByVal hWnd As Long, ByVal lpString As String) As Long

'In code   
    Dim n As Long
    For Each n In GetWindows
        SetWindowText n, "hello world!"
    Next n

---

there is one problam with the hello world,

the code. says it "for each control variable must be Variant or object"

--------
'In code
Dim n As Long
For Each n In GetWindows
SetWindowText n, "hello world!"
Next n
--------

I looked at the help, nothing much, how can you solve this?

Sorry about that, i couldn't test it since it would change all my important windows...

Code:

---

'Change
Dim n As Long
'To
Dim n As Variant

Thank you kedaman, I am starting to see how to use the AddressOf property and how API functions with the handles.

Thank you very much.
