How can I make a form in one project a child in another

forms

I developed a reporting module with a startup form in a separate project in vb.net. I have since created a new vb.net win form project with a midi parent. I would like to call the existing report program and have it open as a child to the neparent.

In VB6 I had routines that would let me set the parent attribute in a form in a separate project.

Is there something similar in vb.net?

What I have tried:

In the VB6 code I have;

Public Declare Function SetParent Lib "user32" (ByVal hWndChild As Long, ByVal hWndNewParent As Long) As Long

routines

Public Function fun_ParentHwnd(Optional nHwnd As Long, Optional bClear As Boolean) As Long


    Dim n   As Long
    
    'Read registry setting for ParentHwnd from Parent form

    n = GetCUSetting("", "ParentHwnd", 0)

    fun_ParentHwnd = n
        
End Function
Sub MakeMeChild(nHwnd As Long)

    Dim nRet    As Long
    
    UBhWnd = fun_ParentHwnd
    
    nRet = SetParent(nHwnd, UBhWnd)
    
    UBhWnd = ubHandle

End Sub
