Data File Parsing in CVI

Question

Hi guys,
I'm new in LabWindows. I have a simple project, which has to parse a .txt file. Only some data inside the txt-File is interesting (the middle part, segment # 1-3 -> see example). The upper and lower part differs in size and is not important. Are there predefined LabWindows function, which I may use, or do I have to code it in C?

... delete your second call of ReadLine and it should work

It works very nice...
The only problem I currently have is, that it only prints out every second line????????
int CVICALLBACK AddCallback (int panel, int control, int event,
                             void *callbackData, int eventData1,
                             int eventData2)
    int error = 0;
    int status = 0;
    int filehandle = 0;
    char str[351]; 
    if (event == EVENT_COMMIT) {
        filehandle = OpenFile("test.dat", VAL_READ_ONLY, VAL_OPEN_AS_IS, VAL_ASCII);
         while(1) {
              status = ReadLine(filehandle, str, 350);
            // end of file reached
              if(status == -2)
                break;    
            // Error found
              else if(status == -1) {   
                //error = GetFmtIOErrr ( );
                break;
            else {
                ReadLine(filehandle, str, 350);
                    strcat(str, "\n");
                    SetCtrlVal (panel, PANEL_ACTIONBOX, str);           
        CloseFile (filehandle);
    return 0;
