Implementing the "Font" feature like the one in INTERNET EXPLORER

.

A sample code to change the fonts in your web browser using webbrowser control.

void CMyBrowser::SetFont(int nFontSize)
{	m_pDisp = NULL; 			// IDISPATCH pointer
	LPOLECOMMANDTARGET pCmdTarg = NULL;

	m_pDisp = m_WebBrowser2.GetDocument(); 	// get the idispatch pointer from webbrowser control
	ASSERT(m_pDisp); 			//check for validity
	
	m_pDisp->QueryInterface(IID_IOleCommandTarget, (LPVOID*)&pCmdTarg); //query for IID_IOleCommandTarget interface 
	ASSERT(pCmdTarg); 			// check for validity

	VARIANT vaFontSize;   			// input argumentsVariantInit(&vaFontSize);
	V_VT(&vaFontSize) = VT_I4;
	V_I4(&vaFontSize) = nFontSize;  	//size of the font you want
	VARIANT vaFontOutput;

	pCmdTarg->Exec(NULL,			// execute just change the font
		       OLECMDID_ZOOM,
		       OLECMDEXECOPT_PROMPTUSER,
		       &vaFontSize,
		       &vaFontOutput);
	
	VariantClear(&vaFontSize); 		//clear the variant variable before freeing its memory

	if (pCmdTarg)   pCmdTarg->Release(); 	// release document's command target
	if (m_pDisp)   m_pDisp->Release();    	// release document's dispatch interface
}

    in resource.h:

    #define ID_BROWSE_FONT_SMALLEST 32769
    #define ID_BROWSE_FONT_SMALL 32770
    #define ID_BROWSE_FONT_MEDIUM 32771
    #define ID_BROWSE_FONT_LARGE 32772
    #define ID_BROWSE_FONT_LARGEST 32773

    in message map:

    ON_COMMAND_RANGE(ID_BROWSE_FONT_SMALLEST, ID_BROWSE_FONT_LARGEST, OnChangeFont)
    ON_UPDATE_COMMAND_UI_RANGE(ID_BROWSE_FONT_SMALLEST, ID_BROWSE_FONT_LARGEST, OnUpdateChangeFont)

    in cpp file:

    void CBrowserView::OnUpdateChangeFont( CCmdUI* pCmdUI )
    {
    VARIANT vaZoomFactor; // input arguments
    VariantInit(&vaZoomFactor);
    ExecWB(OLECMDID_ZOOM, OLECMDEXECOPT_DONTPROMPTUSER, NULL, &vaZoomFactor);
    pCmdUI->SetCheck((int)pCmdUI->m_nID - ID_BROWSE_FONT_SMALLEST == V_I4(&vaZoomFactor));
    }
    void CBrowserView::OnChangeFont( UINT nID )
    {
    int fontSize = nID - ID_BROWSE_FONT_SMALLEST;
    VARIANT vaZoomFactor; // input arguments
    VariantInit(&vaZoomFactor);
    V_VT(&vaZoomFactor) = VT_I4;
    V_I4(&vaZoomFactor) = fontSize;
    ExecWB(OLECMDID_ZOOM, OLECMDEXECOPT_DONTPROMPTUSER, &vaZoomFactor, NULL);
    }
