string concatenation & speed question

[scott meyer]

I have several overloaded methods to emit the HTML code:

try	{
	tgtfile = new CFile(strFileName, CFile::modeCreate | CFile::modeWrite );
}
		
catch(CFileException)
{
	MessageBox("HTML file could not be opened","SDX",MB_ICONERROR);
}

...

void CHotViewView::Emit(char c)
{
	tgtfile->Write(&c,1);
}

void CHotViewView::Emit(CString strString)
{
	tgtfile->Write(strString,strString.GetLength());
}

etc.
