项目结构
创建Activex步骤:
1.选择创建类别(Windows 控件库或类库)
2.设置对应的com属性
AssemblyInfo.cs中须做以下设置:
a.引入命名空间:using System.Security;
b.[assembly: AllowPartiallyTrustedCallers()]
3.生成的证书能正常在IE下安装,需继承IObjectSafety,考虑到所有的生成的证书都需继承自该接口,需写一个基类,代码如下:
a.接口代码:
using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices; namespace LamSoonActivex
{
[ComImport, Guid("CB5BDC81-93C1-11CF-8F20-00805F2CD064")]
[InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
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);
}
}
b.基类代码
using System;
using System.Collections.Generic;
using System.Text; using System.Runtime.InteropServices;
using System.Windows.Forms; namespace LamSoonActivex
{ public class BaseActivex : UserControl, IObjectSafety
{
private Sunisoft.IrisSkin.SkinEngine skinEngine1; #region IObjectSafety 成员 private const string _IID_IDispatch = "{00020400-0000-0000-C000-000000000046}";

private const string _IID_IPersistStorage = "{0000010A-0000-0000-C000-000000000046}";
private const string _IID_IPersistStream = "{00000109-0000-0000-C000-000000000046}";
private const string _IID_IPersistPropertyBag = "{37D84F60-42CB-11CE-8135-00AA004BB851}"; private const int INTERFACESAFE_FOR_UNTRUSTED_CALLER = 0x00000001;
private const int INTERFACESAFE_FOR_UNTRUSTED_DATA = 0x00000002;
private const int S_OK = ;
private const int E_FAIL = unchecked((int)0x80004005);
private const int E_NOINTERFACE = unchecked((int)0x80004002); private bool _fSafeForScripting = true;
private bool _fSafeForInitializing = true; public int GetInterfaceSafetyOptions(ref Guid riid, ref int pdwSupportedOptions, ref int pdwEnabledOptions)
{
//pdwSupportedOptions = 1;
//pdwEnabledOptions = 2;
//throw new Exception("The method or operation is not implemented.");
//以上代码亦能正常运行,SetInterfaceSafetyOptions设置即可 int Rslt = E_FAIL;
string strGUID = riid.ToString("B");
pdwSupportedOptions = INTERFACESAFE_FOR_UNTRUSTED_CALLER | INTERFACESAFE_FOR_UNTRUSTED_DATA;
switch (strGUID)
{
case _IID_IDispatch:
case _IID_IDispatchEx:
Rslt = S_OK;
pdwEnabledOptions = ;
if (_fSafeForScripting == true)
pdwEnabledOptions = INTERFACESAFE_FOR_UNTRUSTED_CALLER;
break;
case _IID_IPersistStorage:
case _IID_IPersistStream:
case _IID_IPersistPropertyBag:
Rslt = S_OK;
pdwEnabledOptions = ;
if (_fSafeForInitializing == true)
pdwEnabledOptions = INTERFACESAFE_FOR_UNTRUSTED_DATA;
break;
default:
Rslt = E_NOINTERFACE;
break;
} return Rslt;
} public int SetInterfaceSafetyOptions(ref Guid riid, int dwOptionSetMask, int dwEnabledOptions)
{
//throw new Exception("The method or operation is not implemented.");
int Rslt = E_FAIL;
string strGUID = riid.ToString("B");
switch (strGUID)
{
case _IID_IDispatch:
case _IID_IDispatchEx:
if (((dwEnabledOptions & dwOptionSetMask) == INTERFACESAFE_FOR_UNTRUSTED_CALLER) &&
(_fSafeForScripting == true))
Rslt = S_OK;
break;
case _IID_IPersistStorage:
case _IID_IPersistStream:
case _IID_IPersistPropertyBag:
if (((dwEnabledOptions & dwOptionSetMask) == INTERFACESAFE_FOR_UNTRUSTED_DATA) &&
(_fSafeForInitializing == true))
Rslt = S_OK;
break;
default:
Rslt = E_NOINTERFACE;
break;
}
return Rslt;
} #endregion private void InitializeComponent()
{
this.skinEngine1 = new Sunisoft.IrisSkin.SkinEngine(((System.ComponentModel.Component)(this)));
this.SuspendLayout();
//
// skinEngine1
//
this.skinEngine1.SerialNumber = "";
this.skinEngine1.SkinFile = "\\Resources\\SportsBlue.ssk";//null;
//
// BaseActivex
//
this.Name = "BaseActivex";
this.Load += new System.EventHandler(this.BaseActivex_Load);
this.ResumeLayout(false); } private void BaseActivex_Load(object sender, EventArgs e)
{
//skinEngine1.SkinFile = LamSoonActivex.Properties.Resources.l.ssk;// @"\Resources\SportsBlue.ssk";
}
}
}
4.证书编码
a.需在证书的[Guid("527A380F-7E26-4fd3-AEA5-010D3E7B73BE")],是在Web页中调用的Id,必须是唯一
b.须引入命名空间 using System.Runtime.InteropServices;
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; namespace LamSoonActivex
{
[Guid("527A380F-7E26-4fd3-AEA5-010D3E7B73BE")]
public partial class FrmLamSoon : BaseActivex
{
public FrmLamSoon()
{
InitializeComponent();
} private void btnLogin_Click(object sender, EventArgs e)
{
if (txtStaff_Id.Text.Length == || txtPwd.Text.Length == )
{
MessageBox.Show("请输入有效的系统登陆信息!", "系统提示", MessageBoxButtons.OK, MessageBoxIcon.Error);
return;
}
}
}
}
5.Web UI调用
2种调用方式: <object id="helloworld"
classid="clsid:527A380F-7E26-4fd3-AEA5-010D3E7B73BE"
codebase="LamSoonActivex.exe">
</object> <object id="helloworld"
classid="clsid:527A380F-7E26-4fd3-AEA5-010D3E7B73BE"
codebase="LamSoonActivex.cab#version=1,0,1,0">
</object>
示例:
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
<title>TestActivex</title>
</head>
<body>
<form id="form1" runat="server">
<div style=" text-align:center"> <object id="activex_test"
classid="clsid:527A380F-7E26-4fd3-AEA5-010D3E7B73BE"
codebase="LamSoonActivex.cab#version=1,0,1,0">
</object> </div>
</form>
</body>
</html>
