I have some problems about releasing my IDirect3DDevice9* pd3dDevice struct. In common files in DXut.cpp has a code like that for releasing structure.


if( pd3dDevice->Release() > 0 )  
{
DXUTDisplayErrorMessage( DXUTERR_NONZEROREFCOUNT );
DXUT_ERR( L"DXUTCleanup3DEnvironment", DXUTERR_NONZEROREFCOUNT );
}

In the beggining everything was ok but when i tried to open some mesh's.When i try to quit program this Error Message coming. Error Message


// Changing this
pd3dDevice->Release() > 0

// to this
pd3dDevice->Release() > 56
// Working

Why i can't release the the structure? How can i fix the problem? Thanks.

The value returned by Release() is the number of references that still exist to the object that just got released. It is usually not recommended that you pay too much attention to this value, unless you know specifics about what references it has. See, reference counting is a way of making sure that an object doesn't get deleted from memory as long as certain bits of code still need it. When you call Release(), it is merely saying that you (or this specific part of code) don't need it anymore. Other parts of code might still need access to it. This is not unexpected.

In short, I doubt anything is wrong with your code.

you should release every directx COM interface by youerself before release the pd3ddevice.the return value is the num of interface you haven't released yet.If you don't do so you will meet a "memery leak" and finally program will break down with an "out of memery" error,this maybe keep on until you restart your computer .
