小编kni*_*ing的帖子

例:

    before: text_before_specific_character(specific_character)text_to_be_deleted
    after: text_before_specific_character

我知道可以用'sed'完成.但我被卡住了.有人可以帮我吗？

我有一个功能:

HWND createMainWindow(P2p_Socket_Machine * toSend){

    HWND hMainWnd = CreateWindow( 
        L"Class",/*(LPCWSTR) nameOfConference.c_str()*/L"Chat",  WS_OVERLAPPED | WS_MINIMIZEBOX | WS_SYSMENU, 
    CW_USEDEFAULT, 0, 600,400, 
    (HWND)NULL, (HMENU)NULL, 
    /*(HINSTANCE)hlnstance*/NULL, NULL 
    ); 

    if (!hMainWnd) { 
        MessageBox(NULL, L"Cannot create main window", L"Error", MB_OK); 
        return 0; 
    }

    CreateWindowA("LISTBOX",NULL, WS_CHILD|WS_VISIBLE|WS_BORDER|WS_VSCROLL|LBS_NOTIFY|LBS_MULTIPLESEL,310,30,255,275,hMainWnd,(HMENU)List_Box,NULL,NULL);

    CreateWindowExA(NULL,"BUTTON", "Refresh", WS_TABSTOP|WS_VISIBLE|WS_CHILD|BS_DEFPUSHBUTTON,385,310,100,24,hMainWnd,(HMENU)Button_Refresh, NULL ,NULL);

    CreateWindowExA(NULL,"BUTTON", "Send", WS_TABSTOP|WS_VISIBLE|WS_CHILD|BS_DEFPUSHBUTTON,385,334,100,24,hMainWnd,(HMENU)Button_Send, NULL ,NULL);

    CreateWindowExA(NULL,"BUTTON", "New", WS_TABSTOP|WS_VISIBLE|WS_CHILD|BS_DEFPUSHBUTTON,385,354,100,24,hMainWnd,(HMENU)Button_New, NULL ,NULL);

    CreateWindowA("EDIT",0,WS_BORDER|WS_VISIBLE|WS_CHILD|ES_LEFT|ES_MULTILINE|WS_VSCROLL|WS_DISABLED,
    10,30,265,275,hMainWnd,(HMENU)Text_Box_Get,NULL,NULL);

    CreateWindowA("EDIT",0,WS_BORDER|WS_VISIBLE|WS_CHILD|ES_LEFT|ES_MULTILINE|WS_VSCROLL,
    10,320,265,45,hMainWnd,(HMENU)Text_Box_Send,NULL,NULL);

    SetWindowLongPtr(hMainWnd,GWLP_USERDATA,(LONG_PTR)toSend);

    ShowWindow(hMainWnd, SW_SHOW); 
    //UpdateWindow(hMainWnd);

    return hMainWnd;

}

这是我的计划的主要部分:

int WINAPI WinMain(HINSTANCE hlnstance, HINSTANCE hPrevInstance, LPSTR IpCmdLine, int 
nCmdShow) 
{
WNDCLASSEX wc; 
    wc.cbSize …

我创建了一个表:

    CREATE TABLE IF NOT EXISTS `markersStorage2` (
      `id` int(11) NOT NULL AUTO_INCREMENT,
      `name` varchar(32) COLLATE utf8_unicode_ci NOT NULL,
      `surname` varchar(32) COLLATE utf8_unicode_ci NOT NULL,
      `id_vk` int(10) NOT NULL,
      `activity_link` varchar(128) COLLATE utf8_unicode_ci NOT NULL,
      `message` varchar(256) COLLATE utf8_unicode_ci NOT NULL,
      `lat` float(10,6) NOT NULL,
      `lng` float(10,6) NOT NULL,
      `type` varchar(32) COLLATE utf8_unicode_ci NOT NULL,
      `id_tile` varchar(15) COLLATE utf8_unicode_ci NOT NULL,
      PRIMARY KEY (`id`)
    ) ENGINE=MyISAM  DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci 

我用它来存储谷歌的谷歌地图标记.

这个表经常更新,我的意思是新的标记被添加到其中

我经常使用这个查询:

    SELECT id, lat,lng FROM markersStorage2 WHERE id_tile LIKE …
