ActiveX開發的教程有不少，我也從中受益不淺，例如如下這幾篇：javascript

基本教程：http://www.cnblogs.com/guenli/articles/1629915.htmlhtml

注意事項：http://jon-lt.iteye.com/blog/1676272java

屬性、方法開發：http://blog.csdn.net/waxgourd0/article/details/7652478c++

可是因爲個人目的是開發一個身份證識別儀的ActiveX控件，所以我就要先仿照識別儀ActiveX開發一個ActiveX。c#

本文講述如何模仿開發一個ActiveX控件，若是對此不感興趣請閱讀系列後續文章。測試

我用vs2012，win8操做系統。ui

新建MFC ActiveX控件工程

咱們選擇ActiveX「運行時不可見」，「關於對話框隨」便選不選均可以。項目生成後結構編碼

建屬性和方法

根據身份證識別儀的測試頁面，咱們知道身份證的識別儀ActiveX必須有如下屬性和方法url

var CVR_IDCard = document.getElementById("CVR_IDCard");                    
var strReadResult = CVR_IDCard.ReadCard();
if(strReadResult == "0"{
    ClearForm();
    document.all['Name'].value = CVR_IDCard.Name; 
    document.all['Sex'].value = CVR_IDCard.Sex;    
    document.all['Nation'].value = CVR_IDCard.Nation; 
    document.all['Born'].value = CVR_IDCard.Born; 
    document.all['Address'].value = CVR_IDCard.Address; 
    document.all['CardNo'].value = CVR_IDCard.CardNo; 
    document.all['IssuedAt'].value = CVR_IDCard.IssuedAt;  
    document.all['EffectedDate'].value = CVR_IDCard.EffectedDate;  
    document.all['ExpiredDate'].value = CVR_IDCard.ExpiredDate;
    document.all['SAMID'].value = CVR_IDCard.SAMID;
    document.all['pic'].src = CVR_IDCard.Pic;
    document.all['Picture'].value = CVR_IDCard.Picture;  
    document.all['PictureLen'].value = CVR_IDCard.PictureLen  
}

咱們先建方法ReadCard，從方法上看，輸入參數應該爲空，返回值應該是個string。在「類視圖」中選擇以下路徑，添加方法spa

對於返回字符串的，咱們選擇BSTR類型，輸入方法名，直接點完成便可。

而後須要建Name、Nation、Born等方法，看來都是字符串類型便可。一樣的路徑，選擇「添加屬性」

類型仍然選擇字符串BSTR，選擇Get/Set方法，輸入屬性名Name

這時在ActiveXTestCtrl.cpp中就會有對應的屬性和方法實現代碼

咱們在這裏作一個最簡單的實現，ReadCard直接返回0，GetName返回「Hello World」

BSTR CActiveXTestCtrl::ReadCard(void)
{
    AFX_MANAGE_STATE(AfxGetStaticModuleState());

    CString strResult;
    strResult = "0";
    return strResult.AllocSysString();
}


BSTR CActiveXTestCtrl::GetName(void)
{
    AFX_MANAGE_STATE(AfxGetStaticModuleState());

    CString strResult;
    strResult = "Hello World";
    return strResult.AllocSysString();
}


void CActiveXTestCtrl::SetName(LPCTSTR newVal)
{
    AFX_MANAGE_STATE(AfxGetStaticModuleState());
    SetModifiedFlag();
}

生成測試

打開ActiveXTest.idl文件，這個至關於dll中的def文件那樣，會有不少控件的關鍵信息。包括接口、classid

經過coclass是ActiveXTest，找到對應的classid是「AF7E1FF8-E4DC-47B8-BAC9-F06832ABB5F2」

//  CActiveXTestCtrl 的類信息
    [
        uuid(AF7E1FF8-E4DC-47B8-BAC9-F06832ABB5F2)
    ]
    coclass ActiveXTest
    {
        [default] dispinterface _DActiveXTest;
        [default, source] dispinterface _DActiveXTestEvents;
    };

那麼咱們能夠用原來識別儀驅動中帶的測試頁面，修改其中的classid爲「AF7E1FF8-E4DC-47B8-BAC9-F06832ABB5F2」，就成爲咱們ActiveX控件的測試頁了，代碼以下

編譯項目，若是出現如下錯誤，別擔憂，不是代碼問題，是由於VS沒有權限註冊ActiveX控件到註冊表

警告 1 warning MSB3075: 命令「regsvr32 /s "f:\ActiveXTest\ActiveXTest\Debug\ActiveXTest.ocx"」已退出，代碼爲 5。請驗證您是否有足夠的權限來運行此命令。 C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V110\Microsoft.CppCommon.targets 1609 5 ActiveXTest

錯誤 2 error MSB8011: Failed to register output. Please try enabling Per-user Redirection or register the component from a command prompt with elevated permissions. C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V110\Microsoft.CppCommon.targets 1621 5 ActiveXTest

咱們訪問生成目錄

新建一個腳本setup.bat

cd /d "%~dp0"
regsvr32.exe ActiveXTest.ocx

而後右鍵，以管理員身份運行

這樣就註冊成功了

咱們還能夠進入註冊表regedit.exe，查看HKEY+CLASSES_ROOT\Wow6432Node(不一樣操做系統這裏不同)\CLSID\

{AF7E1FF8-E4DC-47B8-BAC9-F06832ABB5F2}中，看到這個ID已經對應磁盤上對應路徑的ocx文件了。

運行

若是是VS2010開發，則至此能夠運行測試。可是VS2012開發的項目，仍須要作一些加工——在代碼中實現IObjectSafety接口，參見以下：

用VS2012作MFC ActiveX控件並使用html、c#、c++測試容器：http://blog.csdn.net/zengraoli/article/details/17019513

編譯後，打開上面準備好的「測試頁.html」，點擊「讀卡」按鈕後則顯示了Hello World，用一樣的方式實現其餘屬性。

至此，咱們就實現了一個高仿的身份證識別儀讀取ActiveX控件。

若是要僞造身份證識別儀讀取結果，欺騙業務系統說數據是身份證識別儀讀入的，只須要修改相關GUID。後面再說就太危險了，怕查水錶，就不深刻了。
