Reprint two C Programs

The code is not original. Write it down first:

1. play audio and video (passed in vc6)

# Include <windows. h> # include <stdio. h> # include <mmsystem. h> # include <shellapi. h> # include <afxcom_.h> # pragma comment (Lib, "winmm. lib ") void main () {char STR [128] = {0}; int I = 0; char Buf [128] = {0}; mci_open_parms mciopen; mcierror; mciopen. lpstrdevicetype = "mpegvideo"; mciopen. lpstrelementname = "G :\\ my videos \ MV \ avril_lavigne _-_ girlfriend _ (palladia) (1080 p )-. MPG "; // callback. Of course, you can change the path here to mcierror = mcisendcommand (0, mci_open, mci_open_type | mci_open_element, (DWORD) & mciopen); If (mcierror) {mcigeterrorstring (mcierror, Buf, 128); printf ("% s \ n", Buf); System ("pause");} uint DeviceID = mciopen. wdeviceid; optional mciplay; mcierror = mcisendcommand (DeviceID, mci_play, 0, (DWORD) & mciplay); If (mcierror) {printf ("Send mci_play command failed \ n "); system ("pause") ;}for (I = 1; I <= 500; I ++) {sleep (500); printf ("% d ", I );}}

After you understand it, you may think it is a minor skill. Studing !!!

2. count the number of lines of code in the folder (passed under vc6)

"and"... "These two directories -- they are not visible in the resource manager. // The next dos vertex represents the current directory, and the two vertices represent the upper-level directory. If the current folder and the top-level folder are found, ignore them. If (WFD. cfilename [0] = '. ') continue; If (WFD. dwfileattributes & file_attribute_directory) {tchar szfile [max_path]; wsprintf (szfile, "% s \ % s", lpszpath, WFD. cfilename); findallfile (szfile);} else {tchar szfile [max_path]; wsprintf (szfile, "% s \ % s", lpszpath, WFD. cfilename); file * FP; If (FP = fopen (szfile, "R") = NULL) {printf ("failed to open a file! \ N ");} else {int Len = strlen (WFD. cfilename); If (WFD. cfilename [len-1] = 'C' & WFD. cfilename [len-2] = '. '| WFD. cfilename [len-1] = 'P' & WFD. cfilename [len-2] = 'P' & WFD. cfilename [len-3] = 'C' & WFD. cfilename [len-4] = '. ') {file ++; printf ("% s \ n", lpszpath, WFD. cfilename); char data [1000]; while (fgets (data, 1000, FP )! = NULL) Row ++ ;}} fclose (FP) ;}} while (findnextfile (hfind, & WFD); findclose (hfind );}
