Hidden secret text I heard that there is a software that can hide certain cizes in the graphic file, I have not used it, but this idea is very good, um ... I mean is just as my practice. So I opened WinHex, I tried a variety of different suffix graphics files, I found that there were rare oils to extract: JPG and GIF also said that it is compressed, that BMP (DIB) is simply fans to the extreme, there is nothing Place available. Finally, still find that. PCX is available in some places. After I am, it is simple, I actually consume me for a few hours. Ast for a few hours? Because I am stupid! This doesn't know.), Discovery.) 2D0H bytes are available in the end of the file. Don't underestimate these more than 700 bytes, if you are lovers, all-write, the meat, can be used as the killing weapon. However, in order to avoid the occurrence of tragedy, it is best to hide this kind of East Thaminated. Where is it? .pcx! Look at my code: #include Class MessageInpcx {protected: file * in, * out; file * input; long filesis (file * stream) {Long Curpos, length; curpos = ftell (stream); FSeek Stream, 0L, seek_end; length = ftell (stream); fseek (stream, curpos, seek_set); return length;} void Dothejob (Char filename [12]) {ix ((Input = fopen (filename, "rb") ) == NULL) RETURN; for (int i = 0; I <(filesize (in) -715); i ) PUTC (GETC (IN), OUT); for (i = 0; i <715; i ) { IF (! Feof (Input)) PUTC (INPUT), OUT; Else Putc ('/ 0', out);} fclosell ();} public: messageinpcx () {out = fopen ("out.pcx" , "wb");} void setpcx (char filename [12]) {IN = fopen (filename, "rb");} void operator << = (char filename [12]) {dothejob (filename); return;} }; void main () {MessageInpcx out; out.setpcx ("hehe.pcx"); out << = "a.txt";} You can use the MessageInPCX to be used directly, there is a Warning in compile, no matter it!
