I've tried for so long to get this to work... I put the code to create & display a quad in my main render() function. Of course this will be hidden away in some other functions, but to figure out how to get it to work I put it in my render function. Basically.... Begin Scene 1. Setup Matrices 2. Process Input 3. Draw 3d Scene (building and bouncing balls) 4. "HOPEFULLY" overlay a quad (2 triangles with triangle strip) 5. Draw text End Scene Perhaps from seeing those steps you can see something wrong... I'm out of ideas. I've looked at so many tutorials that my eyes hurt... my code LOOKS right... I just don't see any results no matter how I flip around my vertices. Here's my code, Thank you VERY much for your help & time.

VOID Render()
{
	// Process Keyboard Input & Update Objects accordingly

	ProcessKBInput();
	if(!UpdateObjects())
		MessageBox(NULL,"Failed to Update Objects", "Update Objects (main)", MB_OK);

    // Clear the backbuffer and the zbuffer

    g_pd3dDevice->Clear( 0, NULL, D3DCLEAR_TARGET|D3DCLEAR_ZBUFFER, 
                         D3DCOLOR_XRGB(0,0,255), 1.0f, 0 );
    
    // Begin the scene

    if( SUCCEEDED( g_pd3dDevice->BeginScene() ) )
    {
		RECT destRect;
		SetRect( &destRect, 1, 1, 0, 0 );

        // Setup the world, view, and projection matrices

        SetupMatrices();

		// Render our 3D stuff ... Building + Bouncing Balls

		Building1->Render(g_pd3dDevice);	
		//CP->Render(g_pd3dDevice);


//Code to Draw a Square////////////////////////////////


	LPDIRECT3DVERTEXBUFFER9 g_square;
	CPVertex g_square_vertices[] ={
		{ 250.0f,  200.0f, 1.0f, 0.5f, 0xFFFFFFFF }, // x, y, z, rhw, color

		{ 250.0f,  50.0f,  1.0f, 0.5f, 0xFFFFFFFF },
		{ 400.0f,  200.0f, 1.0f, 0.5f, 0xFFFFFFFF },
		{ 400.0f,  50.0f,  1.0f, 0.5f, 0xFFFFFFFF } };

	if( FAILED( g_pd3dDevice->CreateVertexBuffer( 4*sizeof(CPVertex),
													0, D3DFVF_CUSTOMVERTEX,
													D3DPOOL_DEFAULT, &g_square, NULL ) ) )
	{
		// handle case

	}


	VOID* pVertices;
	if( FAILED( g_square->Lock( 0, sizeof(g_square_vertices), (void**)&pVertices, 0 ) ) )
		return;
	memcpy( pVertices, g_square_vertices, sizeof(g_square_vertices) );
	g_square->Unlock();


	g_pd3dDevice->SetStreamSource(0,g_square,0, sizeof(CPVertex));
	g_pd3dDevice->SetFVF(D3DFVF_CUSTOMVERTEX);
	g_pd3dDevice->DrawPrimitive(D3DPT_TRIANGLESTRIP,0,2);

	char buffer[20];
	long debugFPS = timeGetTime();

		FPSTIME2 = debugFPS;
	}
	FPSTIME = debugFPS;
	gcvt(DEBUGNUM,3,buffer);

Again, I just want to say I highly appreciate the time and effort you experts are willing to give to help people like myself.

I''ll answer my question now... I found a great tutorial by Andy Pike that explains this.

First off, you render your 3d stuff & end your scene.

Second, you setup a new set of matrices for your 2D stuff. (World Matrix etc)

THEN you can render your 2d stuff!

Here''s a link

hehe, Ya i was just doing everything each from to made sure it got done. I just had some ordering issues.

Thanks for the reply
