MFC按行读取txt数据并分割每行数据

CStdioFile file; 

CString strLine,strtemp;

if(!file.Open( "d:\\test.txt ",CFile::modeRead))return;//打开*.TXT这个文件，打开形式为读取 

int row = 0; //定义行变量

while(file.ReadString(strLine))

{ 

char *str = strLine.GetBufferSetLength(strLine.GetLength());

char *p;

if(strLine!="")

{ 

for (p=strtok(str," ");p!=NULL;p=strtok(NULL," "))

{

 strtemp = p;

} 

MessageBox(strtemp);

}

} 

file.Close();
