little help trying to render to a typical Win32 window.

[Eagle_Eye]

Hello, i'm trying to render to a pre_made window and for some reason I get an access violation right here:

Code: Select all

bool CIrrlicht::CreateIrrlichtDeviceEx(video::E_DRIVER_TYPE Type /* = E_DRIVER_TYPE::EDT_DIRECT3D9 */,HWND windowHandle,int width, int height)
{
	ZeroMemory(&this->creationParams,sizeof(SIrrlichtCreationParameters));
	
	creationParams.WindowId = reinterpret_cast<void*>(windowHandle);
	creationParams.DriverType = Type;
	//creationParams.WindowSize = core::dimension2d<s32>(width, height);
	-> g_pDevice = createDeviceEx(creationParams);

	if(g_pDevice)
	{
		MessageBoxA(NULL,"Device Created","OK",MB_OK);
		return true;
	}

}

it returns 0x00000 and i did make sure to initialize it correctly, any advice?
I followed the tutorial but added my own classes and for some reason, the device wont create and it gives an access violation.

Code: Select all

	ZeroMemory(&this->creationParams,sizeof(SIrrlichtCreationParameters));

Do NOT do this. The SIrrlichtCreationParameters structure is not a plain old data type (it has a constructor, destructor, and assignment operator). This is unsafe, and I'm willing to bet that if you remove the call the problem will go away.
