Hi

Does anyone know why the following code causes me a memory leak:

 Help with Code Tags 
 C Syntax (Toggle Plain Text) 
HGLOBAL hGlobal = GlobalAlloc( GMEM_FIXED, aJpegSize );
void* p = GlobalLock(hGlobal);
memcpy((char *)p,imageptr,aJpegSize);	
GlobalUnlock(hGlobal);
IStream* pStream = NULL;
 
if ( CreateStreamOnHGlobal( hGlobal, TRUE, &pStream ) == S_OK);
			{
				if ( aPicture == NULL )
					delete aPicture;
 
				aPicture = Image::FromStream(pStream,0); 	
			}	
		pStream->Release();
		GlobalFree(hGlobal);
HGLOBAL hGlobal = GlobalAlloc( GMEM_FIXED, aJpegSize );
void* p = GlobalLock(hGlobal);
memcpy((char *)p,imageptr,aJpegSize);	
GlobalUnlock(hGlobal);
IStream* pStream = NULL;

if ( CreateStreamOnHGlobal( hGlobal, TRUE, &pStream ) == S_OK);
			{
				if ( aPicture == NULL )
					delete aPicture;
			
				aPicture = Image::FromStream(pStream,0); 	
			}	
		pStream->Release();
		GlobalFree(hGlobal);

NOTE: the imageptr is a pointer to my jpeg image, and aJpegSize is the size of the image. I later go on to do:

Graphics graphics( dc );
graphics.DrawImage( w->aPicture,  0, 0, 320, 240 );
Graphics graphics( dc );
graphics.DrawImage( w->aPicture,  0, 0, 320, 240 );

I'm really stuck, any idea could help!
Thanks in advance,
maldini
