如何检查CString中可用的数字-Visual MFC

Question

There is an edit control (Type: CString) in my program. How to check if this control contains any number? (ex: "abcdef4hg", "xxxyyy12"....)

Answer 1

Just try to check if there is a digit in the string or not. You can use std::isdigit .

#include <cctype>

bool hasDigits(const CString &str)
{
    for(int i = 0; i < str.GetLength(); i++)
    {
        if(std::isdigit(str[i]))
            return true;
    }
    return false;
}
