Methods > Players and stream mixers > LoadSoundSyncFromZip method

Remarks

Loads a specific entry (sound file) from the specified ZIP file through a secondary thread: as you may know, the only way to know the exact song's duration for MP3 files is scanning the file completely and, for very long files, the use of the LoadSoundFromZip method could be quite lengthy and could temporarily freeze the user interface of the container application. This method avoids any user interface blocking and, once completed, a SoundSyncLoaded event will be fired.

Accepted audio formats are the same as seen inside the LoadSoundFromZip method.

For further details about using ZIP management refer to the How to manage ZIP files tutorial.

Syntax

[Visual Basic]

Public Function LoadSoundSyncFromZip (

nPlayerIndex as Int16,

strZipPathname as String,

strPassword as String,

strEntryName as String,

bFailOnLowMemory as Boolean

) as enumErrorCodes

[C#]

public enumErrorCodes LoadSoundSyncFromZip (

Int16 nPlayerIndex,

string strZipPathname,

string strPassword,

string strEntryName,

bool bFailOnLowMemory

);

[C++]

public: enumErrorCodes LoadSoundSyncFromZip (

Int16 nPlayerIndex,

string strZipPathname,

string strPassword,

string strEntryName,

bool bFailOnLowMemory

);

Parameter

Description

nPlayerIndex

Number representing the zero-based index of the player that will load the sound

strZipPathname

String containing the absolute pathname of the ZIP file to load.

strPassword

String containing the optional password for accessing the requested entry; leave it empty if not needed.

strEntryName

String representing the name of the entry to extract and load.

bFailOnLowMemory

Flag that determines if, for security purposes, loading of the given entry should fail in case there should be no enough memory for storing the unzipped entry.

Supported values are the following:

Value	Meaning
false	In case memory shouldn't be enough to contain the unzipped entry, the same would be stored inside a temporary file. The temporary file would be automatically deleted when closing the sound file through the CloseSound method or after loading a new sound file into the given player.
true	In case memory shouldn't be enough to contain the unzipped entry, the method's call would fail.

Return value

Value	Meaning

enumErrorCodes.NOERROR (0)	The song file has been loaded successfully.
Negative value	An error occurred: see the LastError property for further error details or for a list of the possible error values.
