    Trouble with Windows/DirectX programming

    UPDATE:
    I put the
    Code:
    LPDIRECT3D9 g_pDirect3D = NULL;
    LPDIRECT3DDEVICE9 g_pDirect3D_Device = NULL;
    At the top, now all I get is:
    error C2065: 'WndProc' : undeclared identifier

    Update: I just fixed the wndproc thing, just a typo there..

    I compiled, and debuged and got this:

    Code:
    1>main.obj : error LNK2019: unresolved external symbol _Direct3DCreate9@4 referenced in function _WinMain@16
    1>fatal error LNK1120: 1 unresolved externals
    Code:
    
    #include <windows.h>
    #include <d3d9.h>
    
    /// Update 1
    LPDIRECT3D9 g_pDirect3D = NULL;
    LPDIRECT3DDEVICE9 g_pDirect3D_Device = NULL;
    
    // Update 2, changed WinProc to WndProc, silly typo xD
    LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wparam, LPARAM lParam);
    
    int __stdcall WinMain(HINSTANCE hInstance, HINSTANCE hPrevInst, LPSTR lpCmdLine, int nShow)
    {
    	MSG msg;
    
    	WNDCLASSEX wc = { sizeof(WNDCLASSEX), CS_VREDRAW|CS_HREDRAW|CS_OWNDC,WndProc, 
    		0,0,hInstance, NULL, NULL, (HBRUSH)(COLOR_WINDOW+1),NULL, "DX9_TUTORIAL1_CLASS", NULL };
    
    	RegisterClassEx(&wc);
    
    	HWND hMainWnd = CreateWindow(
    		"DX9_TUTORIAL1_CLASS", 
    		"DirectX9 test", 
    		WS_OVERLAPPEDWINDOW, 
    		100,100,
    		300,300,
    		NULL,
    		NULL,
    		hInstance, 
    		NULL);
    
    
    	g_pDirect3D = Direct3DCreate9(D3D_SDK_VERSION);
    
    	D3DPRESENT_PARAMETERS PresentParams;
    
    	memset(&PresentParams, 0, sizeof(D3DPRESENT_PARAMETERS));
    
    	PresentParams.Windowed = TRUE;
    	PresentParams.SwapEffect = D3DSWAPEFFECT_DISCARD;
    
    
    	g_pDirect3D->CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, hMainWnd, 
    		D3DCREATE_SOFTWARE_VERTEXPROCESSING, &PresentParams, &g_pDirect3D_Device);
    
    	ShowWindow(hMainWnd, nShow);
    	UpdateWindow(hMainWnd);
    
    
    	while (GetMessage(&msg, NULL, 0, 0))
    	{
    
    		TranslateMessage(&msg);
    		DispatchMessage(&msg);
    
    	}
    
    
    	return 0;
    
    
    }
    
    LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
    {
    
    	switch(msg)
    	{
    	
    	case WM_DESTROY:
    		PostQuitMessage(0);
    		return 0;
    
    	case WM_PAINT:
    		g_pDirect3D_Device->Clear(0, NULL, D3DCLEAR_TARGET, D3DCOLOR_XRGB(0,0,255),1.0f, 0);
    		g_pDirect3D_Device->Present(NULL, NULL, NULL, NULL);
    		ValidateRect(hwnd, NULL);
    		return 0;
    
    	}
    
    	g_pDirect3D_Device->Release();
    	g_pDirect3D->Release();
    	return DefWindowProc(hwnd, msg, wParam, lParam);
    
    }
    Most of the errors are just saying an unidentifier

    Code:
    (10) : error C2065: 'WndProc' : undeclared identifier
    (27) : error C2065: 'g_pDirect3D' : undeclared identifier

    Did you link with d3d9.lib (I think it's called that)?
    I'm taking it that you're using Visual Studio. In that case, you can add libraries to link against under project options, linker and input (add d3d9.lib).

    Okay, I did it, and I got this:
    Code:
    Unhandled exception at 0x00e2178a in dxtest.exe: 0xC0000005: Access violation reading location 0x00000000.
    dxtest is my project/solution compiled exe file.

    This is Debugging 101, at least before the advent of message boards and the Spoon Feed Method.

    This is where the red break point ball went to:
    Code:
    int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInst, LPSTR lpCmdLine, int nShow)

    No, not the breakpoint (the red ball), but the line where it crashes.

    Well theres an arrow that keeps directing me to this piece of code:
    Code:
    g_pDirect3D_Device->Release();

    Umm no.
    That code release the d3d device, so it must be there.
    If that line causes problems, it means you did something wrong before.

    If that line causes problems, it means you did something wrong before.

    The problem is that you do not release what you acquire.

    Actually, the release on the device should only be called at the end of WinMain (or once when the application closes). You don't want to release your device at every message you receive so what you did is correct.

    I also noticed your d3d object in the WndProc, did you move it too? If not, you should. Always release such objects in the reverse order that they were created.
