VC ++ write registry self-start (switch)

Tchar m_filename [100];
// Cstring m_filename;
Getmodulefilename (null, m_filename, 100 );
Hkey;
Cstring STR = _ T ("software/Microsoft // windows // CurrentVersion // Run ");
If (error_success! = Regcreatekey (HKEY_LOCAL_MACHINE, STR, & hkey ))
{
MessageBox (_ T ("failed to open registry entry "));
Regclosekey (hkey );
Return;
}
Int length = 0;
While (m_filename [length]! = _ T ('/0 '))
Length ++;
If (error_success! = Regsetvalueex (hkey, _ T ("myautorun"), 0, REG_SZ, (const byte *) m_filename, sizeof (tchar) * length ))
{
MessageBox (_ T ("failed to write the Registry "));
Regclosekey (hkey );
}
Regclosekey (hkey );

Put the aboveCodeAdd to yourProgramAny place that can be executed.
If it is an MFC program, it does not need to contain any library files. Others should include <windows. h> and <tchar. h>
I successfully tested it in vc9.
