API实现让子窗体脱离父窗体，实现对立窗口
[解决办法]
'新建一个工程，添加一个MDI窗体，设置Form1为MDI自窗体，在其内添加一个Command1，键入如下代码
Option Explicit
Private Declare Function SetParent Lib "user32" (ByVal hWndChild As Long, ByVal hWndNewParent As Long) As Long
Private Sub Command1_Click()
Dim lngP As Long
lngP = SetParent(Me.hWnd, ByVal 0&)
Command1.Caption = lngP
End Sub
