Hi, everybody
I meet a problem
First
DWORD WINAPI CA::ThreadFuncSound(LPVOID lpParam)
{
DWORD dwResult=0;
Beep(800, 1000000);
return 0;
}
ThenCreat a thread to sound which is suspended
m_hThreadSound = CreateThread(
NULL, // no security attributes
0, // use default stack size
ThreadFuncSound, // thread function
(PVOID)this, // argument to thread function
CREATE_SUSPENDED|THREAD_ALL_ACCESS, // Start the thread with a suspend count of one
&dwThreadId);
And then Start the sound thread
ResumeThread(m_hThreadSound);
Sleep(100);
Now I want to stop the speaker to sound. I ever used SuspendThread(m_hThreadSound) or TerminateThread(m_hThreadSound,0), but they can't work well.
How can I solve this problem?
Appreciate for any suggestions!

Hi there
to terminate a thread
first call GetExitCodeThread() method passing the Thread Handle to it and DWORD reference.
DWORD exitcode
GetExitCodeThread(m_hThreadSound, &exitcode) ;
Now call TerminateThread(m_hThreadSound, exitcode);
actually u were commiting mistake by passing 0 as thread exit code in ur TerminateThread line.
Tell me if i solved ur prob

Thanks
But it does not work well yet.
It seems that this operation can not stop the speaker's sounding.
Have any other way?

Sir , u have passed 1000000 as a second param in Beep method , which means u have played a sound for almost 16 mins and this will block ur thread .
so instead of issuing a command for 16 mins,do it in a While loop
like this
while (true)
{
Beep(800,100);
}
return ;

Could somebody help me? Any information on ID3v2 of the MP3 files and any information of ID3v1 of the WAV, OGG, WMA files is appreciated.

You should try googling for it first!
Anyway, ID3V2[^]
ID3V1[^]
and there's an article on this subject on CP .
Hope this helps

Thanks! Those files I have read but haven't found the info I need. Have you some info on how to read the ID3v2 of the MP3 file? Or the structure of the ID3v2?

If he didn't even follow those links, I ask myself: Do people even look for the info they need nowdays?

If you have some samples , could you send to me?

I want to use following method, but it doesn't work.
HBITMAP hBitmap; // Here hBitmap is already available;
CBitmap *pBitmap;
pBitmap->Attach(hBitmap);
BITMAP bm;
GetObject(hBitmap, sizeof(BITMAP), &bm);
I don't know the function of "LVOID bmBits" in BITMAP structure.
According to MSDN, "LVOID bmBits" is the pointer to the pixel value area,
so I think I can get pixel value (R,G,B) using loop (bm.bmBits)+ +,
unfortunately it cann't work. Maybe it is a pointer to the whole structure,
including BITMAPFILEHEADER, BITMAPINFO ??
Thanks in advance.

maybe u can try this:
unsigned char *px = new unsigned char[bm.bmHeight*bm.bmWidthBytes];
bitmap->GetBitmapBits(bm.bmHeight*bm.bmWidthBytes,px);
Hello World!

Thank twing.
Why would you define the array data type as unsigned char?
But you still present me a heuristic idea.
The following method indeed works well.
int size= bm.bmHeight*bm.bmWidthBytes;
BYTE *px = new BYTE[size];
pBitmap->GetBitmapBits(size,px);
Then, the array px stores the pixel value RGB,
you can also use loop in +4 to get single R,G or B value,
and use forced transform method, int ( px[i]) to get an int type value.
Thanks,

I am taking C# class right and I am having a little trouble w/ my homework. I hope you guys can help me out.
a) Create a class named Game containing a string that holds the name of the game and an integer that holds the maximum number of players. Include get and set methods for each field. Also include tostring() method that overrides the object class's tostring(0) method and returns a string containing the name of the game along w/ the number of players.
b) Create a child class named GameWithTimeLimit that includes an integer time limit in minutes, and get and set methods for the field.
c) Write a program that instantiates an object of each class and demonstartes all the methods.

Hi,
I have a SDI Visual C++ 6 application with a CFormView.
In the CFormCiew, I have multiple dialogs that I can access by a CTabCtrl on the first view.
In one of the pages I have a ComboBox that I want to update the selection when I open a file for example.
Unfortunately, I can update this ComboBox even if I have add a member data of type CComboBox in the page class.
The only time that I can access the ComboBox is in the OnInitDialog() member function. But if I quit this page and I come back, I did not have acces again to the ComboBox control.
Does anyone has tips ?
Thanks,
Claude

Use OnSetActive() instead.

Can anyone help me in this?

Fire up the macro explorer. Find a suitable module, or create a new one. Add this to the module:
Sub BuggerOff()
Dim i As Integer
For i = 1 To DTE.Windows.Count()
Dim w As Window
w = DTE.Windows.Item(i)
If w.Caption = "Output" Then
w.Close()
End If
Next
End Sub
Then customize a keystroke to call that function.
