我有一个GUID我创建的GUID.NewGUID().现在我想用特定的32位整数替换它的前32位,同时保持其余的原样.
有这个功能吗？

在我LineChart旁边的平行于x轴的全数字上显示的线条中,显示了许多水平网格线:

我怎么能摆脱这些线？

我有一个在Linux上运行的C++代码,但我在Windows上遇到了Visual C++的错误.代码如下:

struct dependence {
    dependence() {}
    dependence(string CUid, LID sink, LID source, std::string var)
    : CUid(CUid), sink(sink), source(source), var(var) {}

    string CUid;

    LID sink = 0;
    LID source = 0;
    std::string var;
};

struct dependenceCompare {
    bool operator() (const dependence& lhs, const dependence& rhs) const{
    return ((lhs.CUid<rhs.CUid) || (lhs.source<rhs.source) || (lhs.sink < rhs.sink) || (lhs.var < rhs.var));

    }
};

在Windows上运行代码时,我收到以下错误:

x = "ain" in txt
print(x) // True

x = " " in txt
print(x) // True

txt = "The rain in Spain stays mainly in the plain "
x = " " in txt.strip()

print(x) // True ,

即使删除空格后它也是真实的。
