atl simple object - Support

增加方法

atl interface - list testSOW.h:

	STDMETHOD(Add)(LONG x, LONG y, LONG* ret);
	STDMETHOD(Sub)(LONG x, LONG y, LONG* ret);
	STDMETHOD(Mul)(LONG x, LONG y, LONG* ret);
	STDMETHOD(Div)(LONG x, LONG y, LONG* ret);
	STDMETHOD(Mod)(LONG x, LONG y, LONG* ret);
	STDMETHOD(Lg)(LONG x, LONG y, DOUBLE* ret);

Add

STDMETHODIMP CtestSOW::Add(LONG x, LONG y, LONG* ret)
{
	// TODO: Add your implementation code here
	*ret = (x + y);

	return S_OK;
}

Subtract

STDMETHODIMP CtestSOW::Sub(LONG x, LONG y, LONG* ret)
{
	// TODO: Add your implementation code here
	*ret = (x - y);

	return S_OK;
}

Multiply

STDMETHODIMP CtestSOW::Mul(LONG x, LONG y, LONG* ret)
{
	// TODO: Add your implementation code here
	*ret = (x * y);

	return S_OK;
}

Divide

STDMETHODIMP CtestSOW::Div(LONG x, LONG y, LONG* ret)
{
	// TODO: Add your implementation code here
	*ret = (x / y);

	return S_OK;
}

Modulo

STDMETHODIMP CtestSOW::Mod(LONG x, LONG y, LONG* ret)
{
	// TODO: Add your implementation code here
	*ret = (x % y);

	return S_OK;
}

Logarithm

STDMETHODIMP CtestSOW::Lg(LONG x, LONG y, DOUBLE* ret)
{
	// https://en.cppreference.com/w/c/numeric/math/log
	*ret = log(x) / log(y);

	return S_OK;
}

[ActiveXObject](https://docs.microsoft.com/en-us/previous-versions/visualstudio/visual-studio-2010/6958xykx(v=vs.100):

function ActiveXObject(ProgID : String [, location : String])

ActiveXObject

ProgID

必选。

serverName.typeName

其中 serverName 是提供对象的应用程序的名称， typeName 是要创建的对象的类型或类。

location

可选项。

要在其中创建对象的网络访问器的名称。

Unzip cpp-mshtml(gcc).zip and execute DisplayHTML.exe:

Embed an HTML control in your own window using plain C - VC

The Simple directory contains a complete C example with everything in one source file.
Study this to familiarize yourself with the technique of using the browser object in your own window.
It demonstrates how to display either an HTML file on the web or disk, or an HTML string in memory, and creates 2 windows to do such.

Simple.c
Ln1676~Ln1687:

		// Create another window with another browser object embedded in it.
		if ((msg.hwnd = CreateWindowEx(0, &ClassName[0], "test atl", WS_OVERLAPPEDWINDOW,
						CW_USEDEFAULT, 0, CW_USEDEFAULT, 0,
						HWND_DESKTOP, NULL, hInstance, 0)))
		{
			// For this window, display a URL. This could also be a HTML file on disk such as "c:\\myfile.htm".
			DisplayHTMLPage(msg.hwnd, "c:\\users\\xb\\documents\\testatl.html");

			// Show the window.
			ShowWindow(msg.hwnd, nCmdShow);
			UpdateWindow(msg.hwnd);
		}
