I've been writing some code to write audio tracks to a CD using IMAPI. This works fine except Windows Media Player tries to determine the Album name and artist and gets it completely wrong.

Is there anyway of writing the artist / album / track info to the CD?

Where does Media Player store its cache of album info?

How is the album info stored on the CD and is there any utility that will extract the info?

The feature is called CD Text, but take care: it is not supported by older cd drives.
An alternative is CDDB, but I don't know exactly how it works. It does read some identification code from the cd and uses webservers to get the track list.

Don't try it, just do it! Wink | ;-)

the artist info and track info are not stored on the CD, and that's shame if you ask me.

the only thing that is stored, is a CD ID; once retrieved, your software must search the web for the artist and track info on sites like cddb.com ( or the free one but I can't remember the name ); I think those sites offers SDK to use their service.

How do you set the CD ID? I can't see anything from IMAPI.

Is it a value in the cda file?

I took a quick look through the IMAPI docs but I didn't see anything about support for CD Text. Frown | :(

CDDB doesn't use any metadata on the CD. All that is is the client taking a hash of the number of tracks + their lengths, and doing a database lookup for CDs whose contents have the same hash.

To get the value (as a decimal)between two bits in a DWORD,this is what I wrote:
////////////////////////////////////
DWORD CMyBitsDlg::RevealBitsInDW(DWORD theNb,unsigned int lowBit,unsigned int highBit)
{ DWORD valueOfBits=theNb;
valueOfBits &=0xFFFFFFFF << (DWORD)lowBit;
valueOfBits &=0xFFFFFFFF >> (DWORD)(31-highBit);

return valueOfBits;
}
///////////////////////
The DWORD is input as a CString of valid Hex chars.
To format it as a DWORD,I tried:
GetDlgItemText(IDC_MYHEX,hexNb);
sscanf(hexNb, "%08X", &GivenHex);
and:
sscanf("0x"+hexNb, "%I32i", &GivenHex);
Both seem be a wrong formatting.
//////// To display the result:
DWORD value=RevealBitsInDW(GivenHex,lbit,hbit);
strResult.Format("%u",value);
GetDlgItem(IDC_MYRESULT)->SetWindowText(strResult);
////////////// Theresult displayed is not correct.
Where is my error ?
Thanks for any help.

Hello all, sorry this is not a specific C++ question, but I'd like to see a C++ approach. I want to make an application that receives input text, and translate (possibly interactively) every word.

But I can't find any simple API for doing this, my idea is very innocent maybe, but I just only want to have a couple of files like

language1.txt
lang1word -> esperanto

language2.txt
lang2word -> esperanto

....
(as you know, esperanto is an artifficial but universal language, the XML of human languages Smile | :)

After two hours of searching I've only found one free tool with vocabulary files for doing this called Ergane. The problem is those files (language1, language2, ...) are in MS Access format, and there are six tables in each mdb file, I don't want to spend time reversing that ER model since what I want to do seems very easy to me right now.
Any ideas or tips?
regards

ActiveX Controls in Dialogbar

Hello,

I want insert some ActiveX Controls in a CDialogBar with Visual C++.net. I can insert the controls, but the controls are not visible when the program is running.

In Visual C++ 6.0 i have no problems, when I change my DialogBar class, as in the MSDN article "185672 HOWTO: How to initialize child controls in a derived CDialogBar" described.
In addition I can insert in Visual C++ 6.0 variables over the class wizzard.
In C++.net is this not possible.

How can I use ActiveX controls in DialogBars with c++.net and how can I use the class wizard for inserting new variables in the DialogBar.

Thanks and sorry for my bad english Smile | :)
