MFC中小笔记

主要记录下一些有啊没啊的MFC东西。

1、单文档 去掉 无标题：在玩的时候用于FindWindow（class,title）

 

     

BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
if( !CFrameWnd::PreCreateWindow(cs) )
return FALSE;

cs.style &= ~FWS_ADDTOTITLE  ;//////////////////加上这一句.

return TRUE;
}

    

2、鼠标右键操作 ，二级菜单

  POINT t;
 GetCursorPos(&t);
 HMENU hMenu,hPopupMenu;
 hMenu=CreatePopupMenu();
 hPopupMenu=CreatePopupMenu();
 AppendMenu(hMenu,MF_STRING,CW_ABOUT,"11111111");
        AppendMenu(hPopupMenu,MF_STRING,CW_DOCUMENT,"22222222(&D)");
         InsertMenu(hMenu,1,MF_BYPOSITION|MF_STRING|MF_POPUP,(unsigned short)hPopupMenu,"3333333");
        TrackPopupMenu(hMenu,TPM_TOPALIGN,t.x,t.y,0,::GetFocus(),0); 

3、文件文件夹右击菜单 注册表中位置 HKCR_AllFilesystemObjects_ShellEx_ContextMenuHandlers

　　在ATL工程中编辑的位置为FileView 选项卡- SimATL.rgs(*.rgs)

    NoRemove AllFilesystemObjects
    {
        NoRemove ShellEx
        {
            NoRemove ContextMenuHandlers
            {
                ForceRemove SimpleShlExt = s '{×××××××××××××××（ATL-uid）}'
            }
        }
    }
}

4、对多个文件的右击操作（）

HRESULT CSimAti::Initialize(LPCITEMIDLIST pidlFolder,  LPDATAOBJECT lpdobj,   HKEY hkeyProgID)
{        
    //----------省略
        。。。。。。

    //拖拽操作，右击操作 
    //----------------------------------------------
    //extern TCHAR m_files[MAX],m_pzDropFile[20]
    //extern int length;

    int count = ::DragQueryFile(hDrop, 0xFFFFFFFF, NULL, 0);
   
    if (count){
        for (int i=0;i<count;i++){
            DragQueryFile(hDrop,i,m_pzDropFile,MAX_PATH);    
            for (int j=0;j<strlen(m_pzDropFile);j++)
            {
                m_files[length+j]=m_pzDropFile[j];
            
            }
            
           length+=strlen(m_pzDropFile);
           m_files[length++]=0x20;//0x20 ASCII为空格，以空格来间隔各个文件
        }
        m_files[length]=NULL;
        
    }
    //----------------------------------------------

        
    
    GlobalUnlock(hDrop);
    //Release the medium storage
    ::ReleaseStgMedium(&mdmSTG);
    //return SUCCEED flag
    return S_OK;
}

5、对文件-右键菜单的点击行为

HRESULT CSimAti::InvokeCommand(LPCMINVOKECOMMANDINFO lpici)
{
    USES_CONVERSION;

    int nFlag = HIWORD(lpici->lpVerb);//如果 nFlag 不为０则说明 pici->lpVerb 指向一个以''''结尾的字符串
    int nMnuId = LOWORD(lpici->lpVerb);//user clicked menu's id  //用户当前点击的菜单项ID 
    if(0 != nFlag){
        return E_INVALIDARG;
    }
    //response the menu item command 
    switch(nMnuId){    
    case 0:
        {
        ///*形成后的命令行格式为  *.exe E/D file1name空格 filename2空格 filename3...*/
        m_files[0]='E';//
        m_files[1]=0x20;//空格
        ShellExecute(NULL,"open","temp.exe",m_files,NULL, SW_SHOW );
            return S_OK;
        }        
        break;
        
    case 1:
        {
            m_files[0]='D';//标识符 E 
          m_files[1]=0x20;
    ShellExecute(NULL,"open","temp.exe",m_files,NULL, SW_SHOW );
        return S_OK;
        }
        break;
    }
    return E_INVALIDARG;
}
