esp debug error

hi all, i have an interface class with those functions:

virtual iCamera*		getCamera() = 0;
virtual iWorldPosition*	getWorldPos() = 0;
virtual cMaterial*		getMaterial() = 0;
virtual iLight*			getLight() = 0;
virtual iVertexBuffer*	getVB() = 0;
virtual cTexture*		getTexture() = 0;
virtual iFont*			getFont() = 0;
virtual iRenderTarget*	getRenderWindow(HWND hWnd) = 0;
virtual cRenderTexture*	getRenderTexture() = 0;

i implement them in an dll: .h:

     
cTexture*		getTexture();
iCamera*		getCamera();
iWorldPosition* getWorldPos();
iVertexBuffer*	getVB();
iLight*			getLight();
cMaterial*		getMaterial();
iFont*			getFont();
iRenderTarget*	getRenderWindow(HWND hWnd);
cRenderTexture*	getRenderTexture(){return NULL;};

.cpp:

   
cTexture* cAdapterDX9_0::getTexture()
{return new cTextureDX9_0(this->D3Ddevice);}

iVertexBuffer* cAdapterDX9_0::getVB()
{return new cVertexBufferDX9_0(D3Ddevice);}

cMaterial* cAdapterDX9_0::getMaterial()
{return new cMaterialDX9_0();}

iCamera* cAdapterDX9_0::getCamera()
{return new cCameraDX9_0();}

iWorldPosition* cAdapterDX9_0::getWorldPos()
{return new cWorldPositionDX9_0();}

iFont* cAdapterDX9_0::getFont()
{return new cFontDX9_0(D3Ddevice);}

iLight* cAdapterDX9_0::getLight()
{return new cLightDX9_0();}

when i call this functions in one project it runs fine but in another (MFC)project it gives this debug error: The value of ESP wa not saved across a function call. This is usually the result of calling a function declared with one calling convention with a function pointer declared with a different calling convention. (module: chkesp.c) other functions from the dll are working fine thx in advance [edited by - freaker13 on April 19, 2004 6:21:05 AM]
