Try this,
//File reading---- CFileException ex; //catch exceptions CFile myfile; //Open file myfile.Open("c:/b.txt", CFile::modeRead, &ex); //Get length int z=myfile.GetLength(); //create temp buffer with all data including line breaks char* data=new char[z]; //read data myfile.Read(data,z); //Extract only data, remove line breaks int* value=new int[z/3]; for(int i=0;i -

what do you man when you say that you want to store the data in int. do you want to store the number of bytes you read from a file in int'or do you want to store the data in int(in that case -> ???????)? regards, Eli

Assuming that your file has CR/LF at end of each line. The code below might be easier
CStdioFile myFile("Sample.txt",CFile::modeRead ); CString myBuffer; int myInteger = 0; LPCTSTR pMyBuffer, pMyBufferEnd; myFile.ReadString(myBuffer); while(!myBuffer.IsEmpty()){ pMyBuffer = myBuffer; pMyBufferEnd = pMyBuffer + myBuffer.GetLength(); cout << pMyBuffer << endl; for( pMyBuffer;pMyBuffer <= pMyBufferEnd; pMyBuffer++) { if((*pMyBuffer < '0') ||(*pMyBuffer > '9')) { cout << myInteger << (LPCTSTR) " "; myInteger = 0; } else { myInteger *= 10; myInteger += *pMyBuffer - 48; } } cout << endl; myFile.ReadString(myBuffer); } myFile.Close();I'll e-mail you a demo. It's a console app (don't worry it supports MFC!) Good luck, happy programming, Alton
