\section{\class{wxMemoryFSHandler}}\label{wxmemoryfshandler}
This \helpref{wxFileSystem}{wxfilesystem} handler can store arbitrary
data in memory stream and make them accessible via URL. It is particularly
suitable for storing bitmaps from resources or included XPM files so that
they can be used with wxHTML.
Filenames are prefixed with "memory:", e.g. "memory:myfile.html".
Example:
\begin{verbatim}
#ifndef __WXMSW__
#include "logo.xpm"
#endif
void MyFrame::OnAbout(wxCommandEvent&)
{
wxBusyCursor bcur;
wxFileSystem::AddHandler(new wxMemoryFSHandler);
wxMemoryFSHandler::AddFile("logo.pcx", wxBITMAP(logo), wxBITMAP_TYPE_PCX);
wxMemoryFSHandler::AddFile("about.htm",
"<html><body>About: "
"<img src=\"memory:logo.pcx\"></body></html>");
wxDialog dlg(this, -1, wxString(_("About")));
wxBoxSizer *topsizer;
wxHtmlWindow *html;
topsizer = new wxBoxSizer(wxVERTICAL);
html = new wxHtmlWindow(&dlg, -1, wxDefaultPosition,
wxSize(380, 160), wxHW_SCROLLBAR_NEVER);
html->SetBorders(0);
html->LoadPage("memory:about.htm");
html->SetSize(html->GetInternalRepresentation()->GetWidth(),
html->GetInternalRepresentation()->GetHeight());
topsizer->Add(html, 1, wxALL, 10);
topsizer->Add(new wxStaticLine(&dlg, -1), 0, wxEXPAND | wxLEFT | wxRIGHT, 10);
topsizer->Add(new wxButton(&dlg, wxID_OK, "Ok"),
0, wxALL | wxALIGN_RIGHT, 15);
dlg.SetAutoLayout(true);
dlg.SetSizer(topsizer);
topsizer->Fit(&dlg);
dlg.Centre();
dlg.ShowModal();
wxMemoryFSHandler::RemoveFile("logo.pcx");
wxMemoryFSHandler::RemoveFile("about.htm");
}
\end{verbatim}

\func{}{wxMemoryFSHandler}{\void}
Constructor.
\membersection{wxMemoryFSHandler::AddFile}\label{wxmemoryfshandleraddfile}
\func{static void}{AddFile}{\param{const wxString\& }{filename}, \param{wxImage\& }{image}, \param{long }{type}}
\func{static void}{AddFile}{\param{const wxString\& }{filename}, \param{const wxBitmap\& }{bitmap}, \param{long }{type}}
Add file to list of files stored in memory. Stored
data (bitmap, text or raw data)
will be copied into private memory stream and available under
name "memory:" + \arg{filename}.
The \arg{type} argument is one of {\tt wxBITMAP\_TYPE\_XXX} constants.
Note that you must use a \arg{type} value (aka image format)
that wxWidgets can save (e.g. JPG, PNG, see \helpref{wxImage
documentation}{wximage})!

\func{static void}{AddFileWithMimeType}{\param{const wxString\& }{filename}, \param{const wxString\& }{textdata}, \param{const wxString\& }{mimetype}}
\func{static void}{AddFileWithMimeType}{\param{const wxString\& }{filename}, \param{const void* }{binarydata}, \param{size\_t }{size}, \param{const wxString\& }{mimetype}}
Like \helpref{AddFile}{wxmemoryfshandleraddfile}, but lets you explicitly
specify added file's MIME type. This version should be used whenever you know
the MIME type, because it makes accessing the files faster.

\membersection{wxMemoryFSHandler::RemoveFile}\label{wxmemoryfshandlerremovefile}

Remove file from memory FS and free occupied memory.
