我尝试用 C# 制作一个带有 COM 可见的 ActiveX。它是一个 Windows 窗体。我成功地将它构建为一个 dll ActiveX,然后我编写了一个 VBScript 代码来调用它。from出现了,但在那之后就消失了。我不知道为什么@@这是我的代码:
C# 代码
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Drawing;
using System.Data;
using System.Text;
using System.Windows.Forms;
using System.Runtime.InteropServices;
using Microsoft.Win32;
using System.Reflection;
namespace ActiveXTestLibrary
{
[ProgId("ActiveXTestLibrary.UserControl")]
[ClassInterface(ClassInterfaceType.AutoDispatch)]
[ComVisible(true)]
public partial class UserControl1 : Form
{
public UserControl1()
{
InitializeComponent();
}
[ComVisible(true)]
public void Hello()
{
this.Show();
}
private void radButton1_Click(object sender, EventArgs e)
{
this.lblResult.Text = "I am a .NET user control happily living \ninside an ActiveX container. Cheers.";
}
[ComRegisterFunction()]
public static void RegisterClass(string key)
{
StringBuilder sb = new StringBuilder(key);
sb.Replace(@"HKEY_CLASSES_ROOT\", "");
RegistryKey k = Registry.ClassesRoot.OpenSubKey(sb.ToString(), true);
RegistryKey ctrl = k.CreateSubKey("Control");
ctrl.Close();
RegistryKey inprocServer32 = k.OpenSubKey("InprocServer32", true);
inprocServer32.SetValue("CodeBase", Assembly.GetExecutingAssembly().CodeBase);
inprocServer32.Close();
k.Close();
}
[ComUnregisterFunction()]
public static void UnregisterClass(string key)
{
StringBuilder sb = new StringBuilder(key);
sb.Replace(@"HKEY_CLASSES_ROOT\", "");
RegistryKey k = Registry.ClassesRoot.OpenSubKey(sb.ToString(), true);
if (k == null)
{
return;
}
k.DeleteSubKey("Control", false);
RegistryKey inprocServer32 = k.OpenSubKey("InprocServer32", true);
inprocServer32.DeleteSubKey("CodeBase", false);
inprocServer32.Close();
}
}
}
和 VBScript:
Sub main
set objTest = CreateObject("ActiveXTestLibrary.UserControl")
objTest.Hello
end sub
call main
