Problem with a pointer to a class pointer

[Hippie Salad]

Im getting an "expression must have pointer-to-class type" error in a function where i have a pointer to a class pointer passed in to. Strange thing is if i cast it, it works just fine.

here's the code:

ID3v2ReturnCodes GetID3v2Tag(ID3v2Tag** ppTag, char FilePath[MAX_PATH])
{
	std::fstream File(FilePath);
	if (!File.fail())
	{
		char Buffer[128];
		File.get(Buffer, 4);

		if (!strcmp(Buffer, "ID3"))
		{
			*ppTag = new ID3v2Tag;										// Works fine
			
			File >> dynamic_cast<ID3v2Tag*>(*ppTag)->mMajorVersion;		// Works fine
			File >> *ppTag->mMajorVersion;								// Error
			File >> dynamic_cast<ID3v2Tag*>(*ppTag)->mRevisionNumber;
			File >> dynamic_cast<ID3v2Tag*>(*ppTag)->mFlags;
			dynamic_cast<ID3v2Tag*>(*ppTag)->mSize = File.get() << 21 | File.get() << 14 | File.get() << 7 | File.get();
			
			
			MessageBox(NULL, "blah", "debug", MB_OK);
		}
		else
			return ID3v2RETURNCODE_NOTAGFOUND;
	}

	else
		return ID3v2RETURNCODE_FILEOPENERROR;
}

Any ideas on why this is happening, how to fix it or an other idea on how to do it?

Thanks in advance

*x->y is equivalent to *(x->y). What you meant to write was (*x)->y.

It works :)

thank you very much helios :)
