DirectX 9 in code:blocks fails on initD3D

Korowai

Hello, i am trying to handle problem with directX 9 and code:blocks. i searched the internet and after installing the sdk properly and used a tutorial to compile the directx code in an static control window of my winapi program. The IDE doesn't give an error, but instead of compiling a grey window the code only does a black window over the other dialog elements, who won't be compiled properly on screen. The programm doesn't shutdown and the window bar still is in function. Does anyone knows what's to do? Here ist the code in cuts:

void initD3D(HWND hDlg30)
{
d3d = Direct3DCreate9(D3D_SDK_VERSION);

D3DPRESENT\_PARAMETERS d3dpp;    

ZeroMemory(&d3dpp, sizeof(d3dpp));    
d3dpp.Windowed = TRUE;    
d3dpp.SwapEffect = D3DSWAPEFFECT\_DISCARD;    
d3dpp.hDeviceWindow = hDlg30;    

d3d->CreateDevice(D3DADAPTER\_DEFAULT,
                  D3DDEVTYPE\_HAL,
                  hDlg30,
                  D3DCREATE\_SOFTWARE\_VERTEXPROCESSING,
                  &d3dpp,
                  &d3ddev);

}

HRESULT CreateDevice(UINT Adapter, D3DDEVTYPE DeviceType, HWND hFocusWindow, DWORD BehaviorFlags,
D3DPRESENT_PARAMETERS *pPresentationParameters, IDirect3DDevice9 **ppReturnedDeviceInterface);

void render_frame(void)
{
d3ddev->Clear(0, NULL, D3DCLEAR_TARGET, D3DCOLOR_XRGB(70, 70, 70), 1.0f, 0);

d3ddev->BeginScene();    

d3ddev->EndScene();    

d3ddev->Present(NULL, NULL, NULL, NULL);

}

void cleanD3D(void)
{
d3ddev->Release();
d3d->Release();
}

And this is the dialog code so far:

BOOL CALLBACK RaumkarteProc(HWND hDlg30, UINT message, WPARAM wParam, LPARAM lParam)
{
PAINTSTRUCT ps;
HDC hdc;
HDC hdcZeichnung;
RECT rect;

static HWND hwndRaumkarteAktion1, hwndRaumkarteAktion2,
hwndRaumkarteHScroll, hwndRaumkarteVScroll, hwndRaum;
int AnzahlGegner;
static int rightWidth=1100;
static int lowerHeight=650;
static int leftWidth=300;
static int upperHeight=50;
bool Kartezeichnen=true;
static int iAktions1index;
static int Aktion1auslesen;
static char Aktion1auswahl\[100\];
int Kartenmobilanzahl;
Kartenmobilanzahl=Zufallsgegner\_Raum.size();
hwndRaum=GetDlgItem(hDlg30,ID\_RAUMKARTE31);
initD3D(hDlg30);

switch (message)
{
    case WM\_INITDIALOG:
    {
        SendDlgItemMessage(hDlg30, ID\_RAUMKARTEAKTIONSLISTE34,LB\_ADDST

Start with the obvious the line that is supposed to make the screen grey is Render_frame

d3ddev->Clear(0, NULL, D3DCLEAR_TARGET, D3DCOLOR_XRGB(70, 70, 70), 1.0f, 0);

That function actually returns a result which isn't used in your code, so use the return and debug it

HRESULT result = d3ddev->Clear(0, NULL, D3DCLEAR_TARGET, D3DCOLOR_XRGB(70, 70, 70), 1.0f, 0);

Now put a breakpoint on the line and check the result is D3D_OK. It tells you in the directx9 help for the function IDirect3DDevice9::Clear will fail if you: Try to clear either the depth buffer or the stencil buffer of a render target that does not have an attached depth buffer. Try to clear the stencil buffer when the depth buffer does not contain stencil data. Creating a Depth Buffer (Direct3D 9) (Windows)[^] It is noted in your initD3D function it doesn't seem to do that It is noted in you setup these two lines you appear to be missing

d3dpp.EnableAutoDepthStencil = TRUE;
d3dpp.AutoDepthStencilFormat = D3DFMT_D16;

In vino veritas

Hello, i tried to fix this, but it still doesn't work. I thougth about it and i guess it could be anything with the ressource file of the dialogue.

LANGUAGE 0, SUBLANG_NEUTRAL
IDD_DIALOG30 DIALOG 0, 0, 1000, 600
STYLE DS_3DLOOK | DS_CENTER | DS_MODALFRAME | DS_SHELLFONT | WS_CAPTION | WS_VISIBLE | WS_POPUP | WS_SYSMENU
CAPTION "Raumkarte"
FONT 8, "Ms Shell Dlg"
{

SCROLLBAR ID_SCROLLBARVER32, 202, 2, 19, 186, SBS_VERT, WS_EX_LEFT
SCROLLBAR ID_SCROLLBARHOR33, 222, 2, 214, 15, 0, WS_EX_LEFT
LISTBOX ID_RAUMKARTEAKTIONSLISTE34, 1, 0, 198, 183, WS_TABSTOP | WS_VSCROLL | LBS_NOINTEGRALHEIGHT | LBS_SORT | LBS_NOTIFY, WS_EX_LEFT

}

The DirectX Code should be in the Static Control "ID_RAUMKARTE31". Maybe i have to add a parameter. Thx & Greetings

I added these lines. There is still no effect. Please take a look at the code i postet with a thread i made in questions. I think it has something to do with the way i manage the edit control where directx is supposed to render. It would be really nice if you take a look in my other thread. Thanks a lot.
