可以用EnumWindow来实现。
Declare Function GetWindowText Lib "user32" Alias "GetWindowTextA" (ByVal hwnd As Long, ByVal lpString As String, ByVal cch As Long) As Long
Declare Function GetWindowTextLength Lib "user32" Alias "GetWindowTextLengthA" (ByVal hwnd As Long) As Long
Public Function EnumWindowsProc(ByVal hwnd As Long, ByVal lParam As Long) As Boolean
Dim sSave As String, Ret As Long
Ret = GetWindowTextLength(hwnd)
sSave = Space(Ret)
GetWindowText hwnd, sSave, Ret + 1
Form1.Print Str$(hwnd) + " " + sSave
'continue enumeration
EnumWindowsProc = True
End FunctionPrivate Sub Form_Load()
Me.AutoRedraw = True EnumWindows AddressOf EnumWindowsProc, 0&
End Sub
