MSchart控件不闪烁刷新

如果在创建MFC时没有选择Sockets支持，

而在以后又想使用CSocket类或Socket的API时，则要做如下修改。

#include
#include
#include
#include "iphlpapi.h"

#pragma comment ( lib, "ws2_32.lib" )
#pragma comment ( lib, "Iphlpapi.lib" )

void main( int argc, char ** argv )
{
int numberOfHost = 1;
struct hostent *remoteHostent;

//处理命令行参数
if ( argc == 3 )
numberOfHost = atoi( argv[2] );
if ( ( argc >3 ) || ( argc < 2 ) )
{
printf( "RmtHost v0.2 - Get remote HostName /MacAddress " );
printf( "by ShotgunLabs ( Shotgun@xici.net ) " );
printf( "Usage　: RmtHost.exe [RemoteIP] " );
printf( "Example: RmtHost.exe 192.168.0.3 " );
printf( " RmtHost.exe 192.168.0.3 255 " );
exit( 0 );
}
//初始化...

float FloatRound(float fNmb, int nBit) { float fMul = (float)pow(10, nBit); float fTmp = fNmb * fMul; return (float)floor(fTmp + 0.5) / fMul; }

m_pSocket->Send((void*)&m_SendData,sizeof(SendData),0); m_pServerSocket->Receive((void*)&m_GetData,sizeof(SendData),0);
