Develop ActiveX controls and create CAB packages

ActiveX controls are used in a project. by referring to the numerous examples on the internet, ActiveX controls are easily implemented;
Then I made a [installation project], which can be used, but I only need to manually click Install On the client. Next, next... I think it is not very nice;
I tried the [CAB project] Again. It seems that no one uses VS2008. After a little effort, I finally found a solution.
We will share this experience with you.

Development tools: Visual Studio 2008
. NET: 2.0
Development language: C #

I. Compile ActiveX Controls
1. Create a Windows Forms control library project]

2. Add a [user control]

3. Drag two Label controls to the interface

4. Add a method for the control to display the current time in the Label.

 

 /// <Summary>
/// Set the current time
/// </Summary>
/// <Param name = "timeStr"> </param>
Public void SetTime (string timeStr)
{
This. label2.Text = timeStr;
}

 

 

 

5. Create an interface:
It is said that the purpose of this interface is to improve program security so that the client IE can pre-execute the ActiveX control without changing the settings.
For this article, we recommend that you:

 using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;
 
namespace HelloBossma
{
    [ComImport, GuidAttribute("CB5BDC81-93C1-11CF-8F20-00805F2CD064")]
    [InterfaceTypeAttribute(ComInterfaceType.InterfaceIsIUnknown)]
    public interface IObjectSafety
    {
        [PreserveSig]
        int GetInterfaceSafetyOptions(ref Guid riid, [MarshalAs(UnmanagedType.U4)] ref int pdwSupportedOptions, [MarshalAs(UnmanagedType.U4)] ref int pdwEnabledOptions);
 
        [PreserveSig()]
        int SetInterfaceSafetyOptions(ref Guid riid, [MarshalAs(UnmanagedType.U4)] int dwOptionSetMask, [MarshalAs(UnmanagedType.U4)] int dwEnabledOptions);
    }
}

6. Let our controls implement this interface.
For a long time to implement this interface, you can find it in this article:

Http://www.pinvoke.net/default.aspx/Interfaces/IObjectSafety.html

7. Add the Guid, ProgId, and ComVisible attributes for our controls.

 

 namespace HelloBossma
{
    [Guid("636B8CE1-7512-464C-B63C-FC75BDCA21DB"), ProgId("HelloBossma.HelloBossmaActiveX"), ComVisible(true)]
    public partial class HelloBossmaActiveX : UserControl, IObjectSafety
    {
        ...
    }
}

 

 

 

8. Open the project properties, and check [Register for Com interoperability] In the generate process]

9. Create a project and go to the binRelease directory.
HelloBossma. dll
HelloBossma. tlb
These two files are required; otherwise, they are not generated successfully.

 

 

 

 

2. Create an ActiveX Setup Installation File
1. Create an installation project

2. Right-click the project, choose add> project output, and select the project above.

3. Open the properties page of the installation project and set the installation URL.
Set http: // localhost/hellobossma
This directory must actually exist to store the generated installation files for the client to download and install.

4. Generate a project
Two files, one exe file and one msi file are generated.

5. Create a website and add the following code to the webpage.
Classid is the Guid of the control.
