	6	\section{\class{wxMemoryFSHandler}}\label{wxmemoryfshandler}
	7
	8	This \helpref{wxFileSystem}{wxfilesystem} handler can store arbitrary
	9	data in memory stream and make them accessible via URL. It is particularly
	10	suitable for storing bitmaps from resources or included XPM files so that
	11	they can be used with wxHTML.
	12
	13	Filenames are prefixed with "memory:", e.g. "memory:myfile.html".
	14
	15	Example:
	16
	17	\begin{verbatim}
	18	#ifndef __WXMSW__
	19	#include "logo.xpm"
	20	#endif
	21
	22	void MyFrame::OnAbout(wxCommandEvent&)
	23	{
	24	wxBusyCursor bcur;
	25
	26	wxMemoryFSHandler::AddFile("logo.pcx", wxBITMAP(logo), wxBITMAP_TYPE_PCX);
	27	wxMemoryFSHandler::AddFile("about.htm",
	28	"<html><body>About: "
	29	"<img src=\"memory:logo.pcx\"></body></html>");
	30
	31	wxDialog dlg(this, -1, wxString(_("About")));
	32	wxBoxSizer *topsizer;
	33	wxHtmlWindow *html;
	34	topsizer = new wxBoxSizer(wxVERTICAL);
	35	html = new wxHtmlWindow(&dlg, -1, wxDefaultPosition,
	36	wxSize(380, 160), wxHW_SCROLLBAR_NEVER);
	37	html->SetBorders(0);
	38	html->LoadPage("memory:about.htm");
	39	html->SetSize(html->GetInternalRepresentation()->GetWidth(),
	40	html->GetInternalRepresentation()->GetHeight());
	41	topsizer->Add(html, 1, wxALL, 10);
	42	topsizer->Add(new wxStaticLine(&dlg, -1), 0, wxEXPAND \| wxLEFT \| wxRIGHT, 10);
	43	topsizer->Add(new wxButton(&dlg, wxID_OK, "Ok"),
	44	0, wxALL \| wxALIGN_RIGHT, 15);
	45	dlg.SetAutoLayout(true);
	46	dlg.SetSizer(topsizer);
	47	topsizer->Fit(&dlg);
	48	dlg.Centre();
	49	dlg.ShowModal();

	52	wxMemoryFSHandler::RemoveFile("about.htm");

	84
	85	Add file to list of files stored in memory. Stored
	86	data (bitmap, text or raw data)
	87	will be copied into private memory stream and available under
	88	name "memory:" + filename.
	89
	90	Note that when storing image/bitmap, you must use image format that wxWindows
	91	can write (e.g. JPG, PNG, see \helpref{wxImage documentation}{wximage})!
