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

	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
	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 message map:


    in cpp file:

    void CBrowserView::OnUpdateChangeFont( CCmdUI* pCmdUI )
    VARIANT vaZoomFactor; // input arguments
    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
    V_VT(&vaZoomFactor) = VT_I4;
    V_I4(&vaZoomFactor) = fontSize;
