一行太长,想分行写用什么符号连接,,VC中.../ OR \

[sdbus]

RT.

[MZP]

\

[HunterForPig]

用 “\”

[晨星]

\
不过一般只在宏定义中使用，因为如果是字符串，那么别写分号就行，如：
char *s = "How "
"are "
"you?";
如果是一般的语句，那么就直接换，比如：
int sum = i +
j;

[msm]

没错 \

[sdbus]

三楼的这样也行????我的是
CString str;
str.format("%d......
...........",a,);
这样行???
显示有102个错误哦,,\这样也不行啊!
请指教

sql.Empty();
sql = " SELECT DISTINCT a.LogID, a.HouseID, a.IPAddress, a.ControllerID,a.FirstTime ,a.FirstInfo, \
a.SecondTime,a.SecondInfo , w.WorkModeName, c.LogicName ,h.OwnerName, h.OwnerMobilePhone, \
h.ResidentName, h.ResidentMobilePhone, r.RoomName, d.DeviceName ,p.PortNum , p.PortType , \
(SELECT u.UserName FROM t_UserInfo u WHERE a.FirstUserID=u.UserID) as FirstUser,\
(SELECT u.UserName FROM t_UserInfo u WHERE a.SecondUserID=u.UserID) as SecondUser \
FROM t_AlarmLog AS a \
INNER JOIN t_AlarmPortLog AS p ON p.LogID=a.LogID \
INNER JOIN t_WorkMode AS w ON w.WorkModeID=a.WorkModeID \
INNER JOIN t_RoomInfo AS r ON r.HouseID=a.HouseID AND r.RoomID=p.RoomID \
INNER JOIN t_DeviceInfo AS d ON d.DeviceID=p.DeviceID \
INNER JOIN t_HouseInfo AS h ON h.HouseID=a.HouseID \
INNER JOIN t_ControlLogicInfo AS c ON c.LogicID=a.LogicID AND c.HouseID=a.HouseID \
WHERE a.FirstInfo is not NULL AND a.SecondInfo IS NOT NULL AND d.DeviceName LIKE '%";
sql += m_alarmtype;
sql +="%'";

注意:在 \ 后门不要跟中文的空格,否则会出错的!

[MZP]

字符串这样写
CString str;
str.format("%d......"
"...........",a,);

[晨星]

告诉你如果是字符串不要写分号，水让你把引号也去了的？
str.format("%d......"
"...........",a,);

[dasiu]

字符串连接的，可以使用“＋”连接符号

[sdbus]

谢谢各位老大,我以为字符串只用一个引号!

[晨星]

字符串是本来只用一对引号，但你要分行就另当别论了，总要有种不同的方案好让编译器知道你换行呀。

[晨星]

不过，即使写在同一行上，两个相邻的字符串，如果中间没有任何其他东西，也会北合并成一个：
char * s = "How " "are " "you?";
等价于：
char * s = "How are you?";
