VB实现全窗体移动

Private Declare Function ReleaseCapture Lib "user32" () As Long Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long,ByVal wMsg As Long,ByVal wParam As Long,lParam As Any) As Long Private Const WM_NCLBUTTONDOWN = &HA1 Private Const HTCAPTION = 2 Private Sub Form_MouseDown(Button As Integer,Shift As Integer,X As Single,Y As Single) If Button = 1 Then ReleaseCapture SendMessage hwnd,WM_NCLBUTTONDOWN,HTCAPTION,0 End If End Sub

我想把form5移动到form3中picture1的位置，下面是我的代码（在form3的code中）： 

Dim r2 As RECT 

GetWindowRect Picture1.hwnd,r2 

Form5.ScaleMode = vbPixels '设置坐标单位为像素

Form5.Move r2.Left,r2.Top 

Form5.Show 

为什么移动的坐标仍然是默认的缇而不是屏幕像素呢？ 
请指教！ 

要实现窗口的正确移动，应该怎么做？

将form5的左上角的位置挪到form3中picture1左上角的位置

'form3中 Private Type rect Left As Long Top As Long Right As Long Bottom As Long End Type Private Declare Function GetWindowRect Lib "user32" (ByVal hwnd As Long,lpRect As rect) As Long Private Declare Function MoveWindow Lib "user32" (ByVal hwnd As Long,ByVal x As Long,ByVal y As Long,ByVal nWidth As Long,ByVal nHeight As Long,ByVal bRepaint As Long) As Long Private Sub Command1_Click() Dim wrect As rect Dim picrect As rect GetWindowRect Picture1.hwnd,picrect GetWindowRect Form5.hwnd,wrect MoveWindow Form5.hwnd,picrect.Left,picrect.Top,wrect.Right - wrect.Left,wrect.Bottom - wrect.Top,True Form5.Show End Sub
