Change the default open mode of MDI in MFC (id_file_open)

In the cxxxapp: onfileopen () method of the app class, do not call cwinapp: onfileopen. Instead, call your own file selection box to obtain the file path and then call cwinapp: opendocumentfile to open the file.

As follows:

Void cmyprjeditdemoapp: onfileopen ()

{

// Todo: add your command handler code here

// The following is the self-added file opening dialog box
Cfiledialog DLG (true );

Int structsize = 0;

DWORD dwversion, dwwindowsmajorversion, dwwindowsminorversion;

Dwversion = getversion ();

Dwwindowsmajorversion = (DWORD) (lobyte (loword (dwversion )));

Dwwindowsminorversion = (DWORD) (hibyte (loword (dwversion )));

If (dwversion <0x80000000)

Structsize = 88;

Else

Structsize = 76;

//

Gisenv * Env = _ getenv ();



DLG. m_ofn.lpstrinitialdir = env-> cur;

DLG. m_ofn.lstructsize = structsize;

DLG. m_ofn.lpstrfilter = "project file (*. MPJ) \ 0 *. MPJ \ 0 all files (*. *) \ 0 *. * \ 0 \ 0 ";

If (idok = DLG. domodal ())

{

Cstring Path = DLG. getpathname ();

// Call cwinapp: opendocumentfile () to pass the path

Cwinapp: opendocumentfile (path. getbuffer (path. getlength ()));

}

 

}
