CFile class readstring read line by line
Separation of each row in front of the name and number
Isolate the Numbers on the controls

CodePudding user response:

Sscanf (readline, "% s % s", prjName, prjValue)
Done!

To filter out the first line!!!!!!

reference 1st floor jacksonfan response:

CFile class readstring read line by line
Separation of each row in front of the name and number
Numbers on the isolated control

How to separate the words and Numbers? I use readString read before, but not separated, please advise,

refer to the second floor shenyi0106 response:

sscanf (readline, "% s % s", prjName, prjValue)
Done!

To filter out the first line!!!!!!

Use this function, the readline is read line by line? Predecessors can give an example?
