Hi. I'm have a little problem with ID3DXFont and showing text. In surface i have stored background image for menu. Place this surface into back buffer and show it isn't problem. Image was showed correctly, BUT if i show any text using ID3DXFont, background image is not yet displayed :-O. Allways is showed only background image, or only text. Source of text displaying : SIZE size; GetTExtExtendPoint32 (m_Font->GetDC(), Text, wcslen (Text), &size); RECT rc; SetRect (&rc, X, Y, X + size.cx, Y + size.cy); m_Font->DrawText (NULL, Text, -1, &rc, DT_LEFT | DT_TOP | DT_NOCLIP, color); Background is showed via StretchRect. Both (image and text) is placed between BeginScene and EndScene. In rendered world (with 3D models) is everything OK (but in rendered world isn't any bitmaps from Surface). Is anybody know, how to solve this problem ? PS : sorry for my poor english. Regards, Petr.

Please post your code from BeginScene() to EndScene().
I think the error could be that you nested your ..->Begin() methods incorrectly.

Code isn't in one source. Class CD3D is basic class :

UINT CD3D::Draw ()
{
int res = -1;

if ((Device3D () != NULL) && (m_GamePos != NULL))
{
if (CheckDevice())
{
m_SurfaceFunc->ClearDevice (); // clear device with Clear function of Direct3DDevice.
if (SUCCEEDED (Device3D ()->BeginScene ()))
{
res = m_GamePos->Draw (); // draws menu, ingame render etc.

// functions to show FPS and camera settings
// FPS is able to show/hide with CTRL+F
// Cam stats is able to show/hide with CTRL+S
m_SurfaceFunc->ShowFPS ();

Device3D ()->EndScene ();

m_SurfaceFunc->Swap (); // swaps backbuffer surface into screen ... represented by Present function
}
}
}
return res;
}

Draw function in Menu class :

DWORD CMenuClass::Draw ()
{
d3d->SurfaceFunc()->StretchRect (TEXT ("menu_back"));
}

StretchRect is classic StretchRect function, that draws from surface with defined surface (in this is surface called "menu_back").

d3d->Device3D()->StretchRect (Source, NULL, m_pBackBuffer, NULL, D3DTEXF_NONE);

Source of ShowFPS is written in my prior post.
