Data caging issue -Urgent Help

[swagatdash]

Hi, Let me explain the situation. I hv developed an application which is capable of sending some files via Blue-tooth. Every time it sends, the file file reaches messaging In-box.

Here comes the problem:
When the user tries to open the file from from in-box it invokes the application(mentioned above).The application has to read the file sitting in in-box according to requirements. While trying so the application fails to read the mentioned file,as it sits in some other private\SID(probably messaging application's) folder other than the application's.

following is the code Application handler:

void CAWGS60Document::OpenFileL(CFileStore*& aFileStore, RFile& aFile)
{
TFileName iFileName;
aFile.FullName(iFileName);
_LIT(KDestFile,"C:\\Private\\EA681F76\\BTFile.xml"); //no extension required
CDocumentHandler* iDocHandler= CDocumentHandler::NewL();
TDataType nullType; //MIME type not set
TInt ret = KErrNone;
TRAPD(err, ret = iDocHandler->CopyL(iFileName,KDestFile,nullType, KEntryAttNormal) );
if( err || ret)
{
//handle error
CEikonEnv::Static()->InfoWinL(_L("FileCopyError"),iFileName);
}
//Get the destination path
TFileName path;
iDocHandler->GetPath(path);
}

Please suggest how to come over the situation other that using allfile capability.

Try handling the file with the RFile handle.

I tryied with the following code but din't help!
Out put:File can't be opened.

void CAWGS60Document::OpenFileL(CFileStore*& aFileStore, RFile& aFile)
{
TFileName iFileName;
aFile.FullName(iFileName);
_LIT(KDestFile,"C:\\Private\\EA681F76\\BTFile.xml"); //no extension required
RFs aRf;
aRf.Connect();
TInt aERROR=aFile.Open(aRf, iFileName, EFileRead);
if(KErrNone == aERROR)
CEikonEnv::Static()->InfoWinL(_L("No error"),iFileName);
else
CEikonEnv::Static()->InfoWinL(_L("File can't be opened"),iFileName);
aRf.Close();
}

I have to confess, I do not know how these things work exactly. However that is absolutely sure that you will not succeed with opening a file in someone else's private folder (without having AllFiles capability). And if this OpenFileL gets an already opened and accessible "RFile &aFile" (this is what I am absolutely not sure about, though the lack of any RFs around suggests that), you should simply try aFile.Read, instead of re-opening the handle, which would probably cause an error even without data caging.

The messaging application will pass you a temporary file handle via the RFile in the OpenFile parameter which you can read from and display or do what ever with. In this case the file handle will be the handle of the file in the messaging app.

At no stage can you "open" a file that is not in the data cage, such as in a private folder that is not your process's or in \sys.

Yep, It's working fine, I will take down your suggation
