About the WAV to WMA of audio ? - C / C++ / MFC Discussion Boards

do you have a simple code for that ?
Thanks

Create an MFC Dialog base project and add 3 button Play, Pause, Stop
1. add avarible
HWND m_Player;
2. On init Dialog add code :
// TODO
m_File = "Path your audio file";
m_Player = MCIWndCreate(GetSafeHwnd(), AfxGetInstanceHandle(), WS_CHILD | MCIWNDF_NOMENU | MCIWNDF_NOPLAYBAR, m_File);
3. On Button Event Play, Stop , Play call it
MCIWndPlay(m_Player);
MCIWndStop(m_Player);
MCIWndPause(m_Player); <-- use MCIWndResume(m_Player) to continue

or, for a broader range of supported file formats look for DirectShow, there are many samples in the DirectX SDK for your needs

hi all,
I want to play audio file on internet with my application, help me that how i can use MCI (platform SDK) to play audio file on my free website.

or some idea to do this.
thanks

I need to write ActiveX control that can retrieve product version from specified file from ftp or http server. Is there any function in MFC that can do this? Can somebody help me?

Nase. Confused | :confused:

Good day ALL.

Such question. I'm try to call SOAP method from NT Service about in the same way:

ISOAPClient* m_pSOAPClient;
HRESULT hr = CoInitializeEx(NULL, COINIT_MULTITHREADED);
hr = CoCreateInstance ( __uuidof (SoapClient), NULL, CLSCTX_INPROC_SERVER,
__uuidof (ISOAPClient),(void**) &m_pSOAPClient );
hr = m_pSOAPClient->mssoapinit( A2BSTR( sURL ), L"", L"", L"" );

As a result of execution the last string I'm get error:
The specified module could not be found.

Funnily what not long ago it's work. But when I write similar code at MFC of console application it's work ok. Confused | :confused:

HELP ME PLEASE!!!!!!!!

I wanna write a small c program to record HTTP request information to a file and I am curious what precautions will I have to take?

I think basically all I will concern myself with is locking the file, writting to file and unlocking file.

The file will be simple in nature...basically append each request after the other and nothing but CSV format I guess.

Anyways, i'm not writting to a database so I don't think I need to secure data before being written to a file, cuz I can't see any way anyone can make data being sent to a file run any system commands or anything.

There will be no SQL injection hacks here Smile | :)

What should I concern myself with...? I wanna make this thing as small and fast as possible...so...I wanna keep it simple... Smile | :)

p.s- I am aware MySQL would be better, but it isn't in this situation...and I am also aware most servers like Apache...already generate log files...but I need my own...

Cheers Smile | :)

Rap off for you,for me,for our human.

I've noticed that on a couple of different installs of Visual Studio 6.0 the auto-complete stops working for some reason. It continues to work on user defined classes, just not included ones. Does anyone know how to fix this or turn it back on?
Ex:
string test;
test. //after the dot operator pop-up menu does not appear nor function definitions on open paren.

Can anyone suggest a way to play an Avi file over a push button control?

I think this one will do it. But the sources are not arranged well.

Download and extract the sources, create a "res" folder and copy
the .ico, .rc2 and .avi-file to this directory. Then it should
compile without problems... Wink | ;)

Hi,

Is it is possible to create a interactive thread or process from a interactive service?

With best Regards,
A.Ilamparithi

The book I'm reading has me create three files:
rectangle.h
- header file with #ifndef RECTANGLE_H #define RECTANGLE_H and ends with #endif .. I'm not sure what these do exactly, but it says to put them in there.

rectangle.cpp
- This one contains the member functions of the class I define in the header file, but there is no main function in it. When I try to compile it I get..
"LIBCD.lib(crt0.obj) : error LNK2001: unresolved external symbol _main"

For the third file it tells me to link the project with the object file that's created from the rectangle.cpp file, but that file wont compile.

I'm using Visual C++ 6.0 and to make the rectangle.cpp I went to New/C++ source file.

Please help Confused | :confused:

oops. looks like I was hitting build instead of compile.. it put the .obj file in a folder called debug.

Now I'm trying to figure out how to link that .obj file with the third file.

Hi there

How to convert double to int?
Q1:
if a double is smaller than 1.4, it will be assign to 1
Ex: 1.3 will be 1

if a double is bigger than 1.4, it will be assign to 2
Ex: 1.5 will be 2

Q2:
if a double is bigger than 1 and smaller than 2, it will be assign to 2
Ex: 1.20 will be 2
2.10 will be 3

Does anyone know the function?
Thanks.

Can't u use a cast?

The word of the day is legs, let's go back to my house and spread the word Poke tongue | ;-P

Q1: Add 0.5 and cast to int.
Q2: (rounding up) is done bey ceil() (and ronding down by floor()).

I can not find sqlcli1.h and sqlenv.h
could you help me ?
thanks

They are discussed in this online manual[^]. It looks like a pair of headers for developing programs to use DB2 databases. If there's a developer kit for the product, they're probably included in it.

I'm trying to write a peice of code to allow me to intercept the close command in the console attached to my application's process so it will prompt the user before destroying the process. Below is the function I wrote for this. It works fine, but the problem is that when the message box pops up it convinces windows the program has stalled, and an end task window opens. Is there any way to prevent this? If it matters, I'm only considering Windows 2000/XP compatibility for this app.

BOOL WINAPI ConsoleHandlerRoutine(DWORD dwCtrlType)
{

 int i;

 switch(dwCtrlType)
 {

 case CTRL_C_EVENT:
 case CTRL_CLOSE_EVENT:
  for(i = 0; i < (MAX_DASMS - 1); i++)
  {
   if(dasmDialogProcInfo[i].handle)
   {
    if( MessageBox(hWnd_console, "All work in open windows will be lost if you terminate the application. Proceed?", "Information", MB_YESNO | MB_ICONQUESTION) == IDYES )
     return FALSE;  //Don't handle this massage so the application will terminate normally
    else
     return TRUE;   //Handle this message and the application will continue running

   }
  }
  break;

 }

 return FALSE;

}

Hi,

I learn that Visual C++ 6.0 is not ansi/iso compatible but Visual studio .net is. Can anybody elaborate a little more on it? Why one is not and the other is?

It is a matter of design from Microsoft. Visual C++ .NET is simply newer and is a better C++ compiler than its predecessors.

Kuphryn

No compiler is actually 100% ansi/iso compatible. Ultimately VC++ 6.0 suffered from Microsoft wanting to ensure backward compatibility and that the standard was still not finalized. In the end, Microsoft responded to customer demand for fuller compatiblity. Now if we could just get them to fix all the goofiness with Visual Studio....

Anyone who thinks he has a better idea of what's good for people than people do is a swine.
