CdRequestAlbumInfo method

Previous pageReturn to chapter overviewNext page

Remarks

 

Given the name of an artist and the title of an album, tries to obtain titles of contained tracks and the related CD cover pictures from the Amazon catalogue.

This method obtains exactly the same information returned by the CddbRequestAlbumInfo method but it doesn't need the CD to be physically available inside the CD drive.

 

When the CD info will be available, the CallbackForRecordersEvents delegate is invoked with the nEvent parameter set to EV_REC_CDDB_ALBUM_INFO_AVAIL and at this point it will be possible:

 

Obtaining the CD album info through the CddbGetAlbumInfo method.
Getting each CD track title through the CddbGetTrackTitle method.

 

This method call will also try to obtain the CD cover pictures available on the Amazon web site: in case it should find them, the CallbackForRecordersEvents delegate is invoked with the nEvent parameter set to

 

EV_REC_CD_COVER_URLS_AVAIL: notifies that the URL pointing to a certain CD cover picture on the Amazon catalogue is available and can be obtained through a call to the GetCdCoverPictureURL method. It's important to note that if one of these pictures should be missing on the Amazon web server, a valid URL will be in any case returned.
EV_REC_D_COVER_SMALL_FILE_AVAIL, EV_REC_CD_COVER_MEDIUM_FILE_AVAIL and EV_REC_CD_COVER_LARGE_FILE_AVAIL:  notify that a certain CD cover picture has been downloaded from the the Amazon catalogue and is now available locally: the local absolute pathname of the picture can at this point be obtained through a call to the GetCdCoverPictureFile method. It's important to note that the downloaded picture files are temporarily stored inside the system defined "Temp" directory and are automatically deleted when the container application is closed.

 

See the How to get pictures of CD covers tutorial for further details.

 

 

Syntax

 

[Visual Basic]

Public Function CdRequestAlbumInfo (

strArtist as string,

strAlbum as string,

strAmazonDeveloperCode as string

) as enumErrorCodes


 

[C#]

public enumErrorCodes CdRequestAlbumInfo (

string strArtist,

string strAlbum,

string strAmazonDeveloperCode

);


 

[C++]

public: enumErrorCodes CdRequestAlbumInfo (

string strArtist,

string strAlbum,

string strAmazonDeveloperCode

Parameter

Description

 

 

strArtist

String representing the artist name: if it shouldn't be complete the search session would try finding the best match.

strAlbum

String representing the album title: if it shouldn't be complete the search session would try finding the best match.

strAmazonDeveloperCode

String representing the Amazon developer code: this string is optional but it's strongly recommended that you obtain a developer code from Amazon; visit the Amazon Web Services site for creating your own account.

 

IMPORTANT TOPIC: starting from May 2009 the developer code is no more enough in order to access Amazon web services; from that date the access must be performed through a combination of the existing developer code and of a new secret key which is provided by Amazon itself to each registered developer. The new secret key can be requested through the Amazon control panel by accessing your Amazon account. Once you have obtained the new secret key, you can use this parameter in order to pass both the developer code and the secret key using the following syntax:

 

"DeveloperCode-----SecretKey"

 

where the existing developer code and the secret key are separated by 5 '-' (minus) characters.
