Introduction

After 6 months of work, here is finally my first MFC program release. This program is a CAM simulator. I am not a software engineer, so please forgive me for errors. If you have questions please let me know. I am sure that you will find them. The lecture of data files was a big problem to me at the beginning, so here is the implementation. I needed to read *.txt files, what the CNC machine generate. Here is an example M X25 Y23 Z25 SPEED1500. This is a block of data, needed to setup the machines. This is a kind of language that the machine use to move on the coordinates over the work space. So in this implementation you can read a full document, splitting the block in the necessary X Y Z and SPEED values. This is my first upload, I have more things to say about this program I will try to improve soon, this short commentary.

void CProgramaDoc::OnFileOpen() 
{
    CString fichero="archivo de C�digo G",temp;

    CFileDialog archivos(true,NULL,fichero,OFN_ALLOWMULTISELECT,
        "Codigo G (*.tap)|*.tap|Codigo G (*.act)|*.act||",NULL);

    if (archivos.DoModal() == FALSE) return;
    fichero=archivos.GetPathName();

    CFile cfFile (fichero, CFile::modeNoTruncate | CFile::modeRead);
    CArchive ar (&cfFile, CArchive::load); 

    if(!ar.ReadString(temp))  return;

    nl=0;
    do
    {
        if(temp.GetLength() == 0) continue;
        strcpy(linea[nl],temp);
        nl++;

    }while(ar.ReadString(temp));
