Center another applications window using it's handle VB.NET

Hi experts...
Is there a way that I can center another applications child window using that windows handle?

Here's what I have written so far but not sure where to go from here:

 

Private Sub CenterWindow(ByVal intHandle As Long)
        Dim iScreenHeight As Long
        Dim iScreenWidth As Long
        '##  PROVIDES SCREEN SIZE IN PIXELS
        iScreenWidth = Screen.PrimaryScreen.WorkingArea.Width
        iScreenHeight = Screen.PrimaryScreen.WorkingArea.Height


        Dim iFormHeight As Long
        Dim iFormWidth As Long

        Dim myRect As RECT
        If GetWindowRect(intHandle, myRect) > 0 Then
            If (myRect.Right - myRect.Left < My.Computer.Screen.WorkingArea.Width) Or (myRect.Bottom - myRect.Top < My.Computer.Screen.WorkingArea.Height) Then
                iFormHeight = myRect.Left
                iFormWidth = myRect.Top

            End If

        End If
        

        '## Next, we need to find the x/y location of the upper right hand corner

        Dim iTopLoc As Long
        Dim iLeftLoc As Long

        iLeftLoc = iFormWidth / 2
        iTopLoc = iFormHeight / 2


    End Sub
