This code snippet demonstrates how to use the Document Handler API for querying whether the system supports a certain MIME type.

This snippet can be self-signed.

MMP file

The following libraries are required:

LIBRARY  apmime.lib    // TDataType
LIBRARY commonui.lib // CDocumentHandler

Header file

#include <DocumentHandler.h>
private:  // Data
CDocumentHandler* iDocHandler;

Source file

#include <DocumentHandler.h>
iDocHandler = CDocumentHandler::NewL(CEikonEnv::Static()->Process());
_LIT8(KAudioBasicMimeType, "audio/basic");
TDataType audioDataType(KAudioBasicMimeType);
TBool result = EFalse;
TRAPD(err, result = iDocHandler->CanOpenL(audioDataType));
if (err == KMimeNotSupported)
// MIME type is not supported
else if (result && !err)
// Basic audio can be handled
else if (!result && !err)
// Basic audio cannot be handled
// Some other error


The Document Handler API has queried whether the audio/basic MIME type is supported by the system.
