郁闷啊。这个类的申明错那里了

vc6没有问题

[Dong]

enum emCreditStyle
{
CREDIT_IDENTITY_CARD = 0,
CREDIT_SOLIDER_CARD
};

CCreditStyle(emCreditStyle, DWORD dwCardNum);

enum emCreditStyle 是定义在内部的，在外部是看不到的，所以
CCreditStyle(emCreditStyle, DWORD dwCardNum);的定义是错误的，
因为外部根本就没有emCreditStyle这一个类型来的。还怎么传入参数？？？

你必须把enum emCreditStyle定义外类的外边。

vc6也肯定存在问题的。因为这是类型的事。

[OnlyHappy]

楼上的。你看下MSDN中的有一代码啊
// enumeration_declarations.cpp
class Card
{
public:
enum Suit
{
Diamonds,
Hearts,
Clubs,
Spades
};
// Declare two constructors: a default constructor,
// and a constructor that sets the cardinal and
// suit value of the new card.
Card();
Card( int CardInit, Suit SuitInit );

// Get and Set functions.
int GetCardinal(); // Get cardinal value of card.
int SetCardinal(); // Set cardinal value of card.
Suit GetSuit(); // Get suit of card.
void SetSuit(Suit new_suit); // Set suit of card.
char *NameOf(); // Get string representation of card.
private:
Suit suit;
int cardinalValue;
};

// Define a postfix increment operator for Suit.
inline Card::Suit operator++( Card::Suit &rs, int )
{
return rs = (Card::Suit)(rs + 1);
}

int main()
{
}

楼主，试试在class CCreditBase;前加上这两句，看还有错误不：

typedef unsigned long DWORD;
typedef bool BOOL;

[Dong]

to OnlyHappy(说好不打脸)

enum我不敢肯定，但假如是class就一定不可以，
但想想，他们都是定义新的类型，应该结果都是一样的吧。

[icecools]

楼上正解
其实把DWORD换成int什么的就对了，那个没定义

[icecools]

我是说 ekschencn(X)

[北极猩猩]

CCreditStyle(emCreditStyle, DWORD dwCardNum);
怎么只有参数类型，没有参数名呢

[icecools]

没有名字也可以的，后面函数实体的时候有就可以了

[蒋晟]

CCreditStyle(CCreditStyle::emCreditStyle emCardStyles, DWORD dwCardNum);
