为什么我的调用DLL会出错：（如解决，另送100分）

[pearlriver]

我的dll使用的是，non-mfc dll,
采用的第三种方法生成类。

为什么我把头文件，lib，dll引用到了当前目录下。

为什么我的调用DLL会出错：提示
'Timer_Node' : 'struct' type redefinition
'CSd_Timer_Queue' : 'class' type redefinition


谁能告我，如解决，当以100分相送

类型重复定义了,去掉多余的定义

楼主 ，
把你的程序贴出看看，

参考一下，这里没有引如lib库，直接调用dll

这是引用dll的 Sd_Timer_Queen.h ********************************************************************/
#ifdef SD_TIMER_QUEUE_EXPORTS
#define SD_TIMER_QUEUE_API __declspec(dllexport)
#else
#define SD_TIMER_QUEUE_API __declspec(dllimport)
#endif

SD_TIMER_QUEUE_API typedef struct Timer_Node //链表的定时器节点
{
unsigned int Nok; //定时器对应的关键帧序号
UINT_PTR Timer_k; //定时器的唯一id标志
struct Timer_Node * next; //定时器指针，指向下一个节点
} Tmr_Node;

// This class is exported from the Sd_Timer_Queue.dll

class SD_TIMER_QUEUE_API CSd_Timer_Queue {
private:
Tmr_Node * pHead; //定时器链表头
public:
CSd_Timer_Queue(void); //构造函数
virtual ~CSd_Timer_Queue(); //析构函数
};
*****************************************************************
这是使用dll的.h

#include "Sd_Timer_Queue.h"
class TestQueen
{
private:
CSd_Timer_Queue * CSd_Timer_Queue1;
public:
TestQueen(CSd_Timer_Queue * CSd_Timer_Queue2); //此函数会认为重复定义
virtual ~TestQueen();
void test1();

};

好在的一张空头支票。你开贴只有20分，说是给100分？呵呵呵。

好了，你这个问题是你的DLL的头文件引起的。
在头文件中加上
#ifndef __Sd_Timer_Queen_h__
#define __Sd_Timer_Queen_h__


//内容

#endif
