Irrlicht Engine

I have changed my code to :
IrrlichtDevice *device = createDevice(video::EDT_DIRECT3D9, core::dimension2d<u32>(800,600), 32, false, true, false, 0);
bool ret1 = device->isWindowActive();
bool ret2 = device->isWindowFocused();
bool ret3 = device->isDriverSupported(EDT_DIRECT3D9);
if(ret1 && ret2 ...

Yes i am quite sure that the device was created : I check it as follow
IrrlichtDevice *device = createDevice(video::EDT_DIRECT3D9, core::dimension2d<u32>(800,600), 32, false, true, false, 0);
if (!device) ShowMessage("Error");
else ShowMessage("Ok");
video::IVideoDriver* driver = device ...

Good evening

A few years ago, i spent some time trying IrrLicht (version 0.8 at that time) with Borland Builder6, and it was - and is still - working properly. I could compile and use most of the examples provided.

Now that i have more time available, i would like to start again with IrrLicht, now ...
