Question

我使用VS 2010中的项目模板构建了一个简单的InteropForms类。它成功构建并在系统中注册库。我可以在VB6中看到它并引用它，但是我在VS2010中添加到类中的公共方法或属性都不可见。

我做错了什么？

Imports Microsoft.InteropFormTools

<InteropForm()> _
Public Class frmWebBrowserPreview
    Private Sub frmWebBrowserPreview_KeyUp(sender As System.Object, e As System.Windows.Forms.KeyEventArgs) Handles MyBase.KeyUp
        If e.KeyCode = Windows.Forms.Keys.Escape Then Hide()
    End Sub

    Private Sub frmWebBrowserPreview_MouseUp(sender As System.Object, e As System.Windows.Forms.MouseEventArgs) Handles MyBase.MouseUp
        Hide()
    End Sub

    Private Sub wbrPreview_DocumentCompleted(sender As Object, e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles wbrPreview.DocumentCompleted
        wbrPreview.Visible = True
    End Sub

    ''' <summary>
    ''' Navigate to the specified URL
    ''' </summary>
    ''' <param name="strURL">The URL string</param>
    Public Function Navigate(strURL As String) As Boolean
        wbrPreview.Navigate(strURL)
    End Function
End Class

Answer 1

模板来自工具包：VB6 InteropForm Library

VS2012不支持（还......）...... Toolkit for VS2012

我明白了。您必须向相关方法添加InteropFormMethod属性，然后重建包装器。

    ''' <summary>
''' Navigate to the specified URL
''' </summary>
''' <param name="strURL">The URL string</param>
<InteropFormMethod()> _
Public Function Navigate(strURL As String) As Boolean
    wbrPreview.Navigate(strURL)
End Function

InteropForms类方法在VB6中不可见
