They both work fine for me (Win/XP, Vstudio v6). What compiler/system are you using?

OK, here's what you need to do: (1) Somewhere near the start of your program, seed the random number generator using time of day. This ensures that you don't get the same numbers every time: srand((unsigned)time(NULL)); (2) Then, every time you need a random number (betrween 0 and iN) ifile=(rand() % (unsigned)(iN)); That should do it.

I've been using the following function with success. It returns TRUE if a connection is available, and takes less than a sec in either case: BOOL Online() { DWORD dwState = 0; DWORD dwSize = sizeof(DWORD); return InternetQueryOption(NULL, INTERNET_OPTION_CONNECTED_STATE, &dwState, &dwSize) && (dwState & INTERNET_STATE_CONNECTED); } Credit: I got this from Paul Dilascia's column in MSDN mag a while back.

(1) Read all song (file) names into an array (say N items) (2) Pick a random number between 1 and N and use that entry from your array.

The functions you need are: waveOutOpen() waveOutPrepareHeader() waveOutWrite() waveOutClose()

Try replacing: AfxBeginThread(THREADD1,NULL); with: AfxBeginThread(THREADD1,NULL,0,0,0,NULL);

Here are a couple of places to start: http://www.codeproject.com/script/articles/beginners.asp http://www.planet-source-code.com/vb/Tutorial/Default.asp?lngWId=3 http://devcentral.iftech.com/articles/MFC/default.php Good luck.

If, by drive, you mean a disk partition, then you can use GetDiskFreeSpace or GetDiskFreeSpaceEx, or just get my routine GET_DISK_SPACE from: http://www.neurophys.wisc.edu/ravi/software/diskspace/

Sure, you can try something like: bool equal(double val) { if(fabs(val) < 0.00000000001) return true; else return false; }

One way is to override OnCtlColor(), as follows: (1) In your message map, add: ON_WM_CTLCOLOR() (2) Then, add the following function to your Dialog class: (replace CMyDialog with whatever is the proper name in your case) HBRUSH CMyDialog::OnCtlColor(CDC *pDC,CWnd *pWnd,UINT nCtlColor) { HBRUSH hbr = CDialog::OnCtlColor(pDC,pWnd,nCtlColor); if(nCtlColor == CTLCOLOR_DLG) { // Dialog background color (Blue) hbr = CreateSolidBrush(RGB(0,0,255)); return hbr; } return hbr; } You can use this method to change the color of pretty much any element of your dialog.

Did you remember to include: #define GET_X_LPARAM(lp) ((int)(short)LOWORD(lp)) #define GET_Y_LPARAM(lp) ((int)(short)HIWORD(lp)) in your file?

You can't see the actual code, just the machine language binary numbers put out by the compiler/assembler/linker.
