Switch between full-screen and non-full-screen APS

On csdn, I see a lot of questions about how to implement it on PPC. Program Full Screen. I have collected and sorted it out here. Post the information that I passed the test. Code .

1. Full Screen

Rect RC;
Setrect (& rc, 0, 0, getsystemmetrics (sm_cxscreen), getsystemmetrics (sm_cyscreen ));
: Movewindow (m_hwnd, RC. Left, RC. Top, RC. Right, RC. Bottom, true );
: Shfullscreen (m_hwnd, shfs_hidetaskbar | shfs_hidesipbutton | shfs_hidestarticon );
You can add the above Code to your message response function in full screen mode, with no Start Menu or input method.

2. Restore normal display

Rect RC;
Setrect (& rc, 0, 0 + getsystemmetrics (response), getsystemmetrics (sm_cxvirtualscreen), getsystemmetrics (sm_cyvirtualscreen)-getsystemmetrics (sm_cymenu)-getsystemmetrics (response) + 3 ); // There is a "+ 3" here.
: Movewindow (m_hwnd, RC. Left, RC. Top, RC. Right, RC. Bottom, true );
: Shfullscreen (m_hwnd, shfs_showtaskbar | shfs_showsipbutton | shfs_showstarticon );

The comments in the Code are to deal with the customer area height is not enough, there will be a black line below, who have a better way to communicate.

3. Display and hide menus.

// Create a menu
Shmenubarinfo MBI;
Memset (& MBI, 0, sizeof (shmenubarinfo ));
MBI. cbsize = sizeof (shmenubarinfo );
MBI. dwflags = shcmbf_hmenu;
MBI. hwndparent = m_hwnd;
MBI. ntoolbarid = idr_menubar1;
MBI. hinstres = _ module. getmoduleinstance ();
Shcreatemenubar (& MBI );

// Hide the menu
Hwndhwndmb = shfindmenubar (m_hwnd );
: Showwindow (hwndmb, sw_hide); // This is written as: showwindow (hwndmb, sw_showmaximized). The full screen menu is displayed, haha.

// Restore the display of the menu
: Showwindow (hwndmb, sw_show );
When the restore menu is displayed, the menu handle hwndmb can only be obtained from the above. If shfindmenubar (m_hwnd) is used here, a null value is obtained. I guess this is because it is hidden.

About full screen. There are some code snippets on csdn.

You need to add it during DLG initialization.

Shinitdlginfo Shidi;
Zeromemory (& Shidi, sizeof (Shidi ));
Shidi. dwmask = shidim_flags;
Shidi. dwflags = shidif_fullscreennomenubar | shidif_sipdown;
Shidi. hdlg = m_hwnd;
If (! Shinitdialog (& Shidi ))
{
Return false;
}
This code can also be used. However, I prefer the above two sections of code. Haha

Today, we try to implement a lockscreen by using a false/transparent full screen window. It is found that the full screen is a little problematic.

1. directly execute the Code listed above in the DLG or view. The Start menu bar at the top of the mobile phone screen cannot be hidden. When a form is created, a message is sent to the form itself. The preceding problem can be solved by simulating a button message.

2. When the form is full-screen and false-transparent, you can find a way to remove the close button on the far right of the menu bar. I found it on csdn. Find two lines of code:

: Shdonebutton (m_hwnd, shdb_hide );
Modifystyle (ws_caption, ws_minimizebox, swp_nosize );

The test shows that the button in the upper right corner can be hidden successfully.

Today, I tested the above code in an MFC DLG project. The menu bar below is always unavailable. The menu bar or toolbar is not created in my code!
I carefully read the cdialog code. Something found

// Delete the menu bar, which is actually a tool bar ccontrolbar *
M_pwndemptycb-> destroywindow ();
Delete m_pwndemptycb;
M_pwndemptycb = NULL;

// Hide the input method button. Remember to restore it after the program exits. Haha
Cwnd * hwndtaskbar = findwindow (text ("ms_sipbutton"), null );
Hwndtaskbar-> showwindow (sw_hide );
