I have just written my application frame work again, I am however, currently experiences error relating to hwnd. I've been debugging my program for a couple of hours now, seems like I am out of options, I would appreciate it someone more experienced than I could look over the code and throw me some indications as to were my problems have arisen from.

tl;dr hwnd problem, need help

The problem currently 'seems' related to:

swapChainDesc.OutputWindow = *hWnd;

I am left with an access read violation error

My code is organised such that:

dxGeometry->dxD3D.h->dxSystem->winMain

Screenshot of output:

I'm currently rewriting large areas of the framework, trying to eliminate issues with resources not getting allocated correctly. This should hopefully narrow the problem down.

You can't dereference an HWND. It's a handle, not a pointer. Just copy the handle right into the swap chain description.

I wrote the application frame work out again, I'm down this error now:

m_dxd3d CXX0030: expression cannot be evaluated.

When called from my render method:

void dxSystem::render()
{
m_dxd3d->beginScene();

m_dxd3d->endScene();

}

my render method is what is called in winMain.cpp

begin scene just contain the standard functions:

ClearRenderTargetView()
ClearDepthStencilView()

and

Present()

Thanks

The value 0xcdcdcdcd is a debug fill value used for uninitialised members. You're not initialising your HWND member to NULL, and you access it before setting it to a valid value.

The issue has been resolved. The HWND element in create a window was not communicating with createdeviceandswapchain outPutwindow
