VC6.0 MFC创建OCX入门-详细完整流程(JS调用测试, 去除安全提示, exe打包)

2017-11-26 18:01 786 查看

一.前言

本文将采用VC6.0 MFC创建OCX, OCX提供两个简单接口供JS在网页中调用,分别是:

Long AddNumber(Long, Long):返回数字相加之和, 整形传入传出.

BSTR AddString(LPCTSTR, LPCTSTR):返回字符串拼接结果, 字符串传入传出.

二.VC6.0制作OCX

创建工程:输入工程名ocxTest, 点OK, 接下来选择默认选项直到完成.

添加方法:

添加Long AddNumber(Long, Long)方法:

添加BSTR AddString(LPCTSTR, LPCTSTR)方法:

添加方法后, VC3个文件共4处新增了代码, 不关注文档结构的同学此处可略过.

ocxTest.odl文件:

OcxTestCtl.h文件:

OcxTestCtl.cpp文件上方:(该文件还有一处改动在下方, 就是我们一会要为方法添加代码的地方, 详见下一步此处略.)

为方法添加代码:

生成OCX并注册:

点击Build->Rebuild All生成ocxTest.ocx.

注册:将ocx根据操作系统位数放到对应目录,

32位放到C:\Windows\System32,64位放到C:\Windows\SysWOW64;

我的是64然后以管理员身份打开CMD窗口运行命令:regsvr32 C:\Windows\SysWOW64\ocxTest.ocx

三.JS调用

调用说明:

以下代码需保存在以.html为后缀的文件,并修改OBJECT标签下的CLASSID;

CLASSID是每个OCX独有的, 它的值存在ocxTest.odl文件最下方的uuid(5E5397D6-B705-49C2-A6AF-7EA9F036F206)括号内;

ID=”myocx”, 这个ID值可以是任意名字, 用来标识OCX对象, 在JS函数调用时使用.

<HTML>
<HEAD>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312"/>
<TITLE>Add Func Test</TITLE>
<script language="javascript" type="text/javascript">

function Button1_onclick() {
var num1 = form1.Num1.value;
var num2 = form1.Num2.value;
try{
var result = myocx.AddNumber(num1, num2);
alert(result);
}
catch(e){
alert(e.name + ": " + e.message);
}
}

function Button2_onclick() {
var str1 = form1.Str1.value;
var str2 = form1.Str2.value;
try{
var result = myocx.AddString(str1, str2);
alert(result);
}
catch(e){
alert(e.name + ": " + e.message);
}
}

</script>
</HEAD>
<BODY>

<OBJECT ID="myocx" CLASSID="CLSID:5E5397D6-B705-49C2-A6AF-7EA9F036F206"></OBJECT>
<form id="form1">
Num1: <input name="Num1" id="Num1" type="text" size=20><br/>
Num2: <input name="Num2" id="Num2" type="text" size=20><br/>
<input id="Button1" type="button" value="AddNumber" onclick="return Button1_onclick()" /><br/><br/>

Str1: <input name="Str1" id="Str1" type="text" size=20><br/>
Str2: <input name="Str2" id="Str2" type="text" size=20><br/>
<input id="Button2" type="button" value="AddString" onclick="return Button2_onclick()" />
</form>

</BODY>
</HTML>

调用结果:

注:请用IE打开, 如果网页无法打开, 在工具->internet选项中将127.0.0.1加入受信任的站点, 并在自定义级别中将activeX启用.

四.去除网页安全提示

说明:

网页打开后的会有如下安全提示, 不介意的同学可忽略此步.

在XXXCtrl.h中:(XXX为工程名)

1.添加头文件:

#include <objsafe.h>

2.在class COcxTestCtrl{}中添加以下代码:

//safety begin
DECLARE_INTERFACE_MAP()
BEGIN_INTERFACE_PART(ObjSafe, IObjectSafety)//去IE安全检测
STDMETHOD_(HRESULT, GetInterfaceSafetyOptions) (//去IE安全检测
REFIID riid,  DWORD __RPC_FAR *pdwSupportedOptions, DWORD __RPC_FAR *pdwEnabledOptions);
STDMETHOD_(HRESULT, SetInterfaceSafetyOptions) (//去IE安全检测
REFIID riid, DWORD dwOptionSetMask, DWORD dwEnabledOptions);
END_INTERFACE_PART(ObjSafe);//去IE安全检测
//safety end

在OcxTestCtl.cpp中添加以下代码:

//safety begin
BEGIN_INTERFACE_MAP(COcxTestCtrl, COleControl)
INTERFACE_PART(COcxTestCtrl, IID_IObjectSafety, ObjSafe)
END_INTERFACE_MAP()

/////////////////////////////////////////////////////////////////////////////
// IObjectSafety member functions

// Delegate AddRef, Release, QueryInterface

ULONG FAR EXPORT COcxTestCtrl::XObjSafe::AddRef()
{
METHOD_PROLOGUE(COcxTestCtrl, ObjSafe)
return pThis->ExternalAddRef();
}

ULONG FAR EXPORT COcxTestCtrl::XObjSafe::Release()
{
METHOD_PROLOGUE(COcxTestCtrl, ObjSafe)
return pThis->ExternalRelease();
}

HRESULT FAR EXPORT COcxTestCtrl::XObjSafe::QueryInterface(
REFIID iid, void FAR* FAR* ppvObj)
{
METHOD_PROLOGUE(COcxTestCtrl, ObjSafe)
return (HRESULT)pThis->ExternalQueryInterface(&iid, ppvObj);
}

const DWORD dwSupportedBits =
INTERFACESAFE_FOR_UNTRUSTED_CALLER |
INTERFACESAFE_FOR_UNTRUSTED_DATA;
const DWORD dwNotSupportedBits = ~dwSupportedBits;

/////////////////////////////////////////////////////////////////////////////
// CXXXCtrl::XObjSafe::GetInterfaceSafetyOptions
// Allows container to query what interfaces are safe for what. We're
// optimizing significantly by ignoring which interface the caller is
// asking for.
HRESULT STDMETHODCALLTYPE COcxTestCtrl::XObjSafe::GetInterfaceSafetyOptions(
REFIID riid,
DWORD __RPC_FAR *pdwSupportedOptions,
DWORD __RPC_FAR *pdwEnabledOptions)
{
METHOD_PROLOGUE(COcxTestCtrl, ObjSafe)

HRESULT retval = ResultFromScode(S_OK);

// does interface exist?
IUnknown FAR* punkInterface;
retval = pThis->ExternalQueryInterface(&riid,
(void **)&punkInterface);
if(retval != E_NOINTERFACE)
{ // interface exists
punkInterface->Release(); // release it--just checking!
}

// we support both kinds of safety and have always both set,
// regardless of interface
*pdwSupportedOptions = *pdwEnabledOptions = dwSupportedBits;

return retval; // E_NOINTERFACE if QI failed
}

/////////////////////////////////////////////////////////////////////////////
// CXXXCtrl::XObjSafe::SetInterfaceSafetyOptions
// Since we're always safe, this is a no-brainer--but we do check to make
// sure the interface requested exists and that the options we're asked to
// set exist and are set on (we don't support unsafe mode).
HRESULT STDMETHODCALLTYPE COcxTestCtrl::XObjSafe::SetInterfaceSafetyOptions(
REFIID riid,
DWORD dwOptionSetMask,
DWORD dwEnabledOptions)
{
METHOD_PROLOGUE(COcxTestCtrl, ObjSafe)

// does interface exist?
IUnknown FAR* punkInterface;
pThis->ExternalQueryInterface(&riid, (void **)&punkInterface);
if(punkInterface)
{ // interface exists
punkInterface->Release(); // release it--just checking!
}
else
{ // interface doesn't exist
return ResultFromScode(E_NOINTERFACE);
}

// can't set bits we don't support
if(dwOptionSetMask & dwNotSupportedBits)
{
return ResultFromScode(E_FAIL);
}

// can't set bits we do support to zero
dwEnabledOptions &= dwSupportedBits;
// (we already know there are no extra bits in mask )
if((dwOptionSetMask & dwEnabledOptions) != dwOptionSetMask)
{
return ResultFromScode(E_FAIL);
}

// don't need to change anything since we're always safe
return ResultFromScode(S_OK);
}
//safety end

最后, 重新编译注册即可.

五.打包成exe安装包

说明:

安装包的作用是, 在执行以后将自动根据操作系统位数,将ocx文件拷贝到系统对应目录(system32 or SysWOW64), 并执行注册.

步骤:

1.准备材料:

(1).ocx文件

(2).register.bat文件

新建文件, 将文件名改为register.bat并写入以下内容:

只需将set fileName=后面改为实际的ocx文件名.

@echo off
set fileName=XXX.ocx
if exist %windir%\SysWOW64 (goto x64) else (goto x86)

:x64
set sys=SysWOW64
set dir=%WINDIR%\%sys%\
set cmd=%dir%%fileName%
xcopy /y "%~dp0%fileName%" "%dir%"
regsvr32 %cmd%
exit

:x86
set sys=System32
set dir=%WINDIR%\%sys%\
set cmd=%dir%%fileName%
xcopy /y "%~dp0%fileName%" "%dir%"
regsvr32 %cmd%
exit

用好压选中上述两个文件打包为setup.zip:

双击setup.zip, 选择自解压->解压标签:

在解压后运行一栏写入:.\register.bat

点确定即可生成setup.exe文件

最后, 以管理员身份运行setup.exe,选择路径解压后即可自动注册!
