After this it will go to OnDestroy() instead of OnInitDialog() Re: Problem with DoModal() jmkhael9-Dec-03 22:51 jmkhael 9-Dec-03 22:51  Can you call GetLastError and see the error string?

Re: Problem with DoModal() jmkhael9-Dec-03 23:40 jmkhael 9-Dec-03 23:40  Did u change the resource file just before it started crashing? Papa while (TRUE) Papa.WillLove ( Bebe ) ; Re: Problem with DoModal() Neha9-Dec-03 23:48 Neha 9-Dec-03 23:48  You are right. I had fixed the problem... Thanks ...... Re: Problem with DoModal() Anonymous10-Dec-03 19:04 Anonymous 10-Dec-03 19:04  what i meant by enumerting the cases was that if you do not create the dialog box within if condition then the WM_DESTROY will get generated and it will destroy you dialog box. if you don't wanna use if condition to create a dialog box then you will have to allocate memory to the dialog box pointer with new opeator. i hope this solves your prob. Re: Problem with DoModal() Bill S10-Dec-03 1:33 Bill S 10-Dec-03 1:33  What kind of controls do you have embedded in this dialog? I seem to remember the need to initialize support for RichEdit Controls prior to their use in a dialog.

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! Re: How to stop a sound thread Abhishek Srivastava9-Dec-03 22:18 Abhishek Srivastava 9-Dec-03 22:18  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 Abhishek Srivastava Software Engg (VC++) India ,Noida Mobile no 9891492921 Re: How to stop a sound thread FlyingDancer10-Dec-03 0:05 FlyingDancer 10-Dec-03 0:05  Thanks But it does not work well yet. It seems that this operation can not stop the speaker's sounding. Have any other way? Re: How to stop a sound thread Abhishek Srivastava10-Dec-03 0:50 Abhishek Srivastava 10-Dec-03 0:50  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 ; Abhishek Srivastava Software Engg (VC++) India ,Noida Mobile no 9891492921 Re: How to stop a sound thread FlyingDancer10-Dec-03 1:43 FlyingDancer 10-Dec-03 1:43  it is not very good for the soud souds off and on, interrupted Is it better if uninterrupted ? ID3 qdping9-Dec-03 19:28 qdping 9-Dec-03 19:28  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. Re: ID3 Bob Stanneveld9-Dec-03 21:46 Bob Stanneveld 9-Dec-03 21:46  You should try googling for it first! Anyway, ID3V2[^] ID3V1[^] and there's an article on this subject on CP . Hope this helps A student knows little about a lot. A professor knows a lot about little. I know everything about nothing. Re: ID3 qdping9-Dec-03 21:59 qdping 9-Dec-03 21:59  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? Re: ID3 markkuk9-Dec-03 23:54 markkuk 9-Dec-03 23:54  Just follow the Developer Info link on the ID3v2 page, or see the sample implementations. Re: ID3 Bob Stanneveld10-Dec-03 2:26 Bob Stanneveld 10-Dec-03 2:26  If he didn't even follow those links, I ask myself: Do people even look for the info they need nowdays?

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. Nianming Re: How to get pixel value in BITMAP? twing9-Dec-03 18:45 twing 9-Dec-03 18:45  maybe u can try this: unsigned char *px = new unsigned char[bm.bmHeight*bm.bmWidthBytes]; bitmap->GetBitmapBits(bm.bmHeight*bm.bmWidthBytes,px); Hello World! Re: How to get pixel value in BITMAP? charmingzuo9-Dec-03 21:03 charmingzuo 9-Dec-03 21:03  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, Ninaming Please help !!! mcsefl999-Dec-03 17:51 mcsefl99 9-Dec-03 17:51  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.
