First, open the CD-ROM
McIndstring ("Set Cdaudio Door Open Wait", NULL, 0, NULL;
Second, close the CD_ROM
McIndstring ("Set Cdaudio Door Closed Wait", NULL, 0, NULL;
Third, turn off the computer
OsversionInfo OsversionInfo; / / Contains the data structure of the operating system version information
OsversionInfo.dwosveionsInfosize = SizeOf (OsversionInfo);
GetversionEx (& OSVersionInfo); // Get operating system version information
IF (OsversionInfo.dwplatformID == Ver_Platform_WIN32_WINDOWS)

}
Fourth, restart the computer

Five, enumerate all fonts
Logfont LF;
Lf.lfcharset = default_charset; // initialize the logfont structure
Strcpy (lf.lffacename, "");

// enumerate the font families
:: ENUMFONTFAMILIESEX ((HDC) DC, & lf,
(FontenumProc) EnumfontFamproc, (LPARAM) THIS, 0);
// Enumerate function
INT Callback EnumfontFamproc (LPENUMLOGFONT LPELF,
LpnewTextMetric LPNTM, DWORD NFONTTYPE, Long LPARAM
{
// Create a Pointer to the dialog window
CDAY7DLG * PWND = (CDAY7DLG *) LPARAM;
// add the font name to the list box
PWnd -> m_ctlfontlist.addstring (lppelf-> elflogfont.lffacename);
// Return 1 to Continue Font Enumeration
Return 1;
}
Where m_ctlfontlist is a list control variable
Sixth, only one program instance is run once, if you have run, exit
IF (FindWindow (NULL, "Program Title")) EXIT (0);
Seven, get the current mouse location
Cpoint pt;
GetCursorpos (& PT); // Get position
Eight, context menu event trigger event: onContextMenu event
Nine, display and hidden programs menu
CWND * PWND = AFXGETMAINWND (); if (b_m) // Hide menu
{
PWND-> SetMenu (NULL);
PWND-> DRAWMENUBAR ();
B_m = false;
}
Else
{
CMenu Menu;
Menu.loadmenu (idR_mainframe); Display menu can also change the menu item
PWND-> SetMenu (& menu);
PWND-> DRAWMENUBAR ();
B_m = true;
Menu.detach ();
}
Ten, get the icon for executable
Hicon Hicon = :: Extracticon (AfxGetInstanceHandle (), _ T ("Notepad.exe"), 0)
IF (Hicon && HiCon! = (HICON) -1)
{
PDC-> Drawicon (10, 10, Hicon);
}
DESTROYICI (HICON);
Eleven, window automatic leaning program demonstration
BOOL AdjustPos (CRECT * LPRECT)
{// automatic side
INT isx = getSystemMetrics; SM_CXFULLSCREEN;
INT isy = getSystemMetrics (SM_CYFULLSCREEN);
Rect rworkarea;
Bool Bresult = SystemParametersInfo (SPI_GetWorkarea, Sizeof (Rect), & RWORKARE

CRECT RCWA;
IF (! BRESULT)
{// If the call is unsuccessful, use GetSystemMetrics to get the screen area.
RCWA = CRECT (0, 0, ISX, ISY);
}
Else

Int ix = lprect-> left;
INT IY = LPRECT-> TOP;
IF (ix {// adjust left //pwnd->etwindowpos (Null, Rcwa.left, iY ,0, 0 ,swp_nosize); LPRECT-> OffsetRect (rcwa.left-ix, 0); AdjustPos (LPRECT); Return True; } IF (IY {// adjustment // pwnd-> setWindowPos (NULL, IX, RCWA.TOP, 0, 0, SWP_NOSIZE); LPRECT-> OffsetRect (0, rcwa.top-iy); AdjustPos (LPRECT); Return True; } IF (ix lpRect-> width ()> rcwa.right - detastep && = rcwa.right-lprect-> w Idth ()) {// adjust the right // pWnd-> setwindowpos (null, rcwa.right-rcw.width (), iY, 0, 0, swp_nosize; LPRECT-> OffsetRect (rcwa.right-lprect-> right, 0); AdjustPos (LPRECT); Return True; } IF (IY LPRECT-> Height ()> RCWA.BOTTOM - DETASTEP && IY! = RCWA.BOTTOM-LPRECT -> Height ()) {// adjustment // pWnd-> SetwindowPos (NULL, IX, RCWA.BOTTOM-RCW.HEIGHT (), 0, 0, SWP_NOSIGHT; LPRECT-> OffsetRect (0, rcwa.bottom-lprect-> bottom); Return True; } Return False; } // Then use the procedure call in the onMoveing event. CRECT R = * prect; AdjustPos (& R); * prect = (RECT) R; 12. Add a menu item to the system menu Add a menu item to the system menu to make the following three steps: First, use the Resource Symbols dialog (select Resource Symbols in the View menu ... Dialogue) Defines the menu item ID, which should be greater than 0x0f and less than 0xF000; Second, call CWnd :: getSystemMenu to get the pointer to the system menu and call CWnd :: appendmenu to put the menu Item Add to the menu. The next example adds two new items to the system menu. INT CMAINFRAME :: OnCreate (lpcreatestruct lpcreatestruct) { ... // Make Sure System Menu Item Is in The Right Range. Assert (IDM_MYSYSITEM <0xF000); // Get Pointer to System Menu. CMenu * psysmenu = getSystemMenu (false); Assert_Valid (psysmenu); // Add a separator and our menu item to system menu. CSTRING STRMENUITEM (_T ("New Menu Item"); Psysmenu-> appendmenu (mf_separator); Psysmenu-> appendmenu (mf_string, idm_mysysiSISISISISIM, STRMENUITEM); ... } Thirteen, run other procedures // 1, run email or URL Char szmailaddress [80]; STRCPY (SzmailAddress, "Mailto: Netvc@21cn.com"); Shellexecute (Null, "Open", Szmailaddress, Null, NULL, SW_SHOWNORMAL); // 2, run the executable Winexec ("NOTEPAD.EXE", SW_SHOW); // Run 14. Dynamic increase or delete menu 1, add menu //Add to Cmenu * mainmenu; Mainmenu = AFXGETMAINWND () -> getMenu (); // Get the main menu (MainMenu-> getSubmenu (0)) -> appendmenu (mf_separator); // Add a separator (mainmenu-> getSubmenu (0)) -> appendmenu (mf_string, id_app_about, _t ("always on & Top ")); // Add new menu item Drawmenubar (); // Heavy painting menu 2. Delete the menu //delete Cmenu * mainmenu; Mainmenu = AFXGETMAINWND () -> getMenu (); // Get the main menu CString Str; For (INT I = (MainMenu-> GetSubMenu (0)) -> getMenuItemCount () - 1; i> = 0; I -) // Number of items to get menu. { (Mainmenu-> GetSubmenu (0)) -> GetMenustring (i, str, mf_byposition); // Copy the label of the specified menu item to the specified buffer. Explanation of MF_BYPosition. IF (str == "always on & top") // If we have just increased menu items, then delete. { (Mainmenu-> GetSubmenu (0)) -> DeleteMenu (i, mf_byposition); Break; } Fifteen, changing the icon of the app Static changes: Modify the icon resource IDR_MAINFRAME. It has two icons, one is 16 * 16, the other is 3 2 * 32, pay attention to modify together. Dynamic changes: Send a WM_SETICON message to the main window. The code is as follows: HiCon Hicon = AFXGetApp () -> Loadicon (IDI_ICON); Assert (hic); AFXGETMAINWND () -> SendMessage (WM_SETICON, TRUE, (LPARAM) HICON; XVI, another way to change the window title Use statement cWnd * m_pcWnd = AFXGETMAINWND (), then call SetWindowTe in the following form XT () function: SetWindowText (* m_pcwnd, (lpctstr) m_windowtext); // m_windowtext can be a CST Ring class variable. 17. Copying image data by enhancement metafile on the clipboard The following code copies the image data to any application through the meta file, which can be placed in the CVIEW derived letter. Number.
