我在程序开始的头文件定义了CWnd *m_pWnd = NULL;
#include "Winsock2.h"
//CWnd *m_pWnd = NULL;
CWnd *m_pWnd = NULL;
class CDlgMain : public CDialog
{
// Construction
public:
CDlgMain(CWnd* pParent = NULL); // standard constructor
~CDlgMain()
{
//ClntCloseNetwork();
//SerCloseNetwork();
if(!(m_shareInfo==NULL))
{
m_shareInfo=NULL;
}
if(!(m_hShareInfo==NULL))
{
m_hShareInfo=NULL;
}
}
HANDLE m_hShareInfo;
typedef struct share_info3d
{
double cx,cy;
double w,h;
}SHARE_INFO3D;
SHARE_INFO3D *m_shareInfo;
我在程序开始的头文件定义了CWnd *m_pWnd = NULL;
可编译时候说我已经定义了 我确实没在任何地方定义过它 是为什么呢？

有其实的文件包含了你的头文件.
全局变量定义在一个单独的文件里,或者CPP文件里吧.
其它用的地方externTop
