Hi:
I used c # vs2017 to create an activex 64-bit dll project (not any cpu), which compiles and runs normally on the IE browser html webpage, but when I debug the html code in IE browser F12, it prompts that activex is not loaded. The
operating system is Win10 64-bit, IE11. Thank you.
code show as below:
.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices;
namespace ClassLibrary1
{
[ProgId("DemoClassLibrary1.HelloWorld")]
[ClassInterface(ClassInterfaceType.AutoDual)]
[Guid("731632A9-05F4-4B8E-A34E-BCA8168843B9")]
[ComVisible(true)]
public class Class1
{
[ComVisible(true)]
public String SayHello()
{
return "helloworld";
}
}
}

The operation results are divided into two cases:
1. Direct operation, normal:
*. Use IE to open html webpage, it is normal.
2. Using IE F12 to debug html, exception:
*. Open IE
*. Press F12
* .Enter the local html file address
*. Prompt "Object doesn't support property or method 'SayHello'", the html object control (activex control) did not load successfully.
Question:
Why didn't it load successfully? I need to debug html code using IE F12.
