VC常用编程经验(3)

idth())
{//调整右
//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())
{//调整下
//pWnd->SetWindowPos(NULL ,iX,rcWA.bottom-rcW.Height(),0,0,SWP_NOSIZE);
lpRect->OffsetRect(0,rcWA.bottom-lpRect->bottom);
return TRUE;
}
return FALSE;
}
//然后在ONMOVEING事件中使用所下过程调用

CRect r=*pRect;
AdjustPos(&r);
*pRect=(RECT)r;
十二、给系统菜单添加一个菜单项
给系统菜单添加一个菜单项需要进行下述三个步骤：
首先，使用Resource Symbols对话（在View菜单中选择Resource Symbols．．．可以显
示该对话）定义菜单项ID，该ID应大于0x0F而小于0xF000；
其次，调用CWnd::GetSystemMenu获取系统菜单的指针并调用CWnd:: Appendmenu将菜单
项添加到菜单中。下例给系统菜单添加两个新的
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_MYSYSITEM, StrMenuItem);
…
}
十三、运行其它程序
//1、运行EMAIL或网址
char szMailAddress[80];
strcpy(szMailAddress,"mailto:netvc@21cn.com");
ShellExecute(NULL, "open", szMailAddress, NULL, NULL, SW_SHOWNORMAL);
