如何将图形导出为.eps格式文件？我通常将我的图形导出到.pdf文件(使用'pdf'函数),它运行得很好.但是,现在我必须导出到.eps文件.

我在VBA(Excel)中的Student类实现如下

Option Explicit

Private name_ As String
Private surname_ As String
Private marks_ As New Collection


Public Property Get getMean() As Single

    Dim sum As Double
    Dim mark As Double
    Dim count As Integer

    For Each mark In marks_
        sum = sum + mark
        count = count + 1
    Next mark

    getMean = sum / count

End Property

Public Property Let setName(name As String)
    name_ = name
End Property

Public Property Get getName() As String
    getName = name_
End Property …

我正在尝试获取 Powerpoint 演示文稿的处理程序。通常，我使用以下指令：

Set pres = PowerPoint.application.Presentations(pptFile)

我收到以下错误消息：

“activex 组件无法创建对象”

pptFile 应该已经打开

任何想法？

我想暂时运行一个无限循环.基本上,我希望有这样的东西

//do something

while(1){
  //do some work
}

//do some other thing

但我希望修复循环的运行时间,例如,循环可以运行5秒.有人有想法吗？

我有以下课程:

EuropeanOption.h

#pragma once

class OptionPricer;

class EuropeanOption
{
protected:

    double dividend;

    double strike;

    double vol;

    double maturity;

    double spot;

public:
    EuropeanOption(void);

    virtual ~EuropeanOption(void);

    virtual double price(double rate, const OptionPricer& optionPricer) const = 0;

    virtual short getSign() const =0;

    double getDividend() const;
    double getStrike() const;
    double getVol () const;
    double getMaturity() const;
    double getSpot() const;


    void setDividend(double dividend_);
    void setStrike(double strike_);
    void setVol(double vol_);
    void setMaturity(double maturity_);
    void setSpot(double spot_);
};

EuropeanOption.cpp

#include "OptionPricer.h"
#include "EuropeanOption.h"


EuropeanOption::EuropeanOption(void)
{
}


EuropeanOption::~EuropeanOption(void) …
