如何在一个项目中将表单作为另一个项目中的子项 [英] How can I make a form in one project a child in another

问题描述

我在vb.net的一个单独项目中开发了一个带有启动表单的报告模块。之后我创建了一个带有midi父级的新vb.net win表单项目。我想打电话给现有的报告程序，让它作为一个孩子打开到neparent。



在VB6中，我有一些例程，可以让我设置父属性单独项目中的表格。



在vb.net中是否有类似内容？



我尝试了什么：



在VB6代码中我有;

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

例程

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

推荐答案

您可以在当前项目中添加参考到其他项目;只需引用.exe或.dll（如果它是类库）。



（是的; .exe可以像.dll一样访问。因为访问的表单/窗口/类是公开的。

You can add a "reference" in your current project to the "other" project; just reference the .exe or the .dll (if it's a class library).

(Yes; an .exe can be accessed as you would a .dll as long as the accessed form / window / class is public).
