1 创建mfc ActiveX工程

使用vs2105新建一个mfc ActiveX工程，工程名称为ocx_test，如果要在ocx控件中使用对话框，那么就勾选“在插入对象对话框中可用”

更改工程的属性，mfc的使用改为在静态库中使用mfc，字符集未未设置。

2 在控件中使用嵌入对话框

在工程的资源视图中插入一个对话框

然后将对话框的属性修改，style改为child，visible改为true

右键该对话框-添加类

java 调用 cnocr的onnx模型文件输出结果_mfc ActiveX_05

为该对话框创建一个类，名称为CDialog1

在ocx_testCtrl.h文件中添加对话框的头文件

#include"Dialog1.h"//引入对话框类的头文件

在public中添加对话框的变量定义

CDialog1 dlg1;//声明对话框类的对象

接下来在类向导中为Cocx_testCtrl类添加消息响应VM_CREATE

在OnCreate函数中添加：

dlg1.Create(IDD_DIALOG1, this);

接着在onDraw函数改为如下代码：

/*pdc->FillRect(rcBounds, CBrush::FromHandle((HBRUSH)GetStockObject(WHITE_BRUSH)));
	pdc->Ellipse(rcBounds);*/
	dlg1.MoveWindow(rcBounds, true);

接下来生成工程，ocx会自动进行注册。

3 在网页中调用ocx

打开ocx_test.idl这个文件，从如下地方找到ocx的classID

新建一个html，html中的Classid就为上图中的值

<html>
<head>
    <title>test</title>
    <meta charset="utf-8" />
</head>

<body>
<object id=fp_atl border=0 classid=CLSID:16EEE8BE-67C3-4A6D-B892-DBE374724FA8 width="400" height="400";>
</object>
</body>
</html>

然后使用ie浏览器打开这个html，就可以看到网页中出现了含有对话框的ocx控件。

4 去掉浏览器弹出交互不安全提示

java 调用 cnocr的onnx模型文件输出结果_RPC_12

当使用上面创建的这种ocx，在浏览器中会有不安全提示

解决办法是在ocx_testCtrl.h文件中添加一个头文件

#include<ObjSafe.h>

在该类的protect的中添加消息声明：

//去掉安全警告 BEGIN
	DECLARE_INTERFACE_MAP()
	BEGIN_INTERFACE_PART(ObjectSafety, IObjectSafety)
		STDMETHOD(GetInterfaceSafetyOptions)(REFIID riid, DWORD __RPC_FAR *pdwSupportedOptions, DWORD __RPC_FAR *pdwEnabledOptions);
	STDMETHOD(SetInterfaceSafetyOptions)(REFIID riid, DWORD dwOptionSetMask, DWORD dwEnabledOptions);
	END_INTERFACE_PART(ObjectSafety)
	//去掉安全警告 END

接着在ocx_testCtrl.cpp文件中IMPLEMENT_OLECTLTYPE(Cocx_testCtrl, IDS_OCX_TEST, _dwocx_testOleMisc)后面添加：

//注意要将这个里面的类名替换为自己工程的那个类名
//去掉安全警告 BEGIN
BEGIN_INTERFACE_MAP(Cocx_testCtrl, COleControl)
	INTERFACE_PART(Cocx_testCtrl, IID_IObjectSafety, ObjectSafety)
END_INTERFACE_MAP()

	else

	}
}
STDMETHODIMP Cocx_testCtrl::XObjectSafety::SetInterfaceSafetyOptions(
