VC常用编程经验(2)

九、显示和隐藏程序菜单
CWnd *pWnd=AfxGetMainWnd();
if(b_m) //隐藏菜单
{
pWnd->SetMenu(NULL);
pWnd->DrawMenuBar();
b_m=false;
}
else
{
CMenu menu;
menu.LoadMenu(IDR_MAINFRAME); ////显示菜单 也可改变菜单项
pWnd->SetMenu(&menu);
pWnd->DrawMenuBar();
b_m=true;
menu.Detach();
}
十、获取可执行文件的图标
HICON hIcon=::ExtractIcon(AfxGetInstanceHandle(),_T("NotePad.exe"),0);
if (hIcon &&hIcon!=(HICON)-1)
{
pDC->DrawIcon(10,10,hIcon);

}
DestroyIcon(hIcon);
十一、窗口自动靠边程序演示
BOOL AdjustPos(CRect* lpRect)
{//自动靠边
int iSX=GetSystemMetrics(SM_CXFULLSCREEN);
int iSY=GetSystemMetrics(SM_CYFULLSCREEN);
RECT rWorkArea;
BOOL bResult = SystemParametersInfo(SPI_GETWORKAREA, sizeof(RECT), &rWorkAre
a, 0);
CRect rcWA;
if(!bResult)
{//如果调用不成功就利用GetSystemMetrics获取屏幕面积
rcWA=CRect(0,0,iSX,iSY);
}
else
rcWA=rWorkArea;
int iX=lpRect->left;
int iY=lpRect->top;

if(iX < rcWA.left + DETASTEP && iX!=rcWA.left)
{//调整左
//pWnd->SetWindowPos(NULL,rcWA.left,iY,0,0,SWP_NOSIZE);
lpRect->OffsetRect(rcWA.left-iX,0);
AdjustPos(lpRect);
return TRUE;
}
if(iY < rcWA.top + DETASTEP && iY!=rcWA.top)
{//调整上
//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 && iX !=rcWA.right-lpRect->W
