   Novice's trouble with sprites
  I am having a few problems working with sprites...what I am trying to do is get it to load an image into a viewport.I have layout of controls b/c the program is suppose to have really simple image manipulation to it. I use basic shapes to composite them into a larger more complex one. well I can get the layout drawn but when I tried to set up a function to draw the larger pictures into the viewport various problems come up.1)the screen doesn't draw anything or2)it draws the layout into the viewport.I know this probably won't clear things up and I don't know if it's bad form to post code on here but I don't think I know enough about what I am trying to ask.I am ok with C++ but this is my first major project using Direct x (using dx9)here is the code for it and any insight would be appreciated.#define DIRECTINPUT_VERSION 0x0800#include <windows.h>#include <windowsx.h>#include <d3d9.h>#include <d3dx9.h>#include <dinput.h>#include <string>#define SCREEN_WIDTH 1024#define SCREEN_HEIGHT 768#define KEY_DOWN(vk_code) ((GetAsyncKeyState(vk_code) & 0x8000) ? 1 : 0 )#define KEY_UP(vk_code) ((GetAsyncKeyState(vk_code) & 0x8000) ? 0 : 1)#define maxMini 2#pragma comment (lib, "d3d9.lib")#pragma comment (lib, "d3dx9.lib")#pragma comment (lib, "dxguid.lib")#pragma comment (lib, "dinput8.lib")#pragma comment (lib, "d3dx9.lib")LPDIRECT3D9 d3d;LPDIRECT3DDEVICE9 d3ddev;LPD3DXSPRITE d3dspt;LPDIRECTINPUT8 din;LPDIRECTINPUTDEVICE8 dinkeyboard;LPDIRECTINPUTDEVICE8 dinmouse;LPDIRECT3DTEXTURE9 bgLayout;LPDIRECT3DTEXTURE9 arrowUp;LPDIRECT3DTEXTURE9 arrowRight;LPDIRECT3DTEXTURE9 arrowDown;LPDIRECT3DTEXTURE9 arrowLeft;LPDIRECT3DTEXTURE9 shiftLeft;LPDIRECT3DTEXTURE9 shiftRight;LPDIRECT3DTEXTURE9 addShape;LPDIRECT3DTEXTURE9 removeShape;LPDIRECT3DTEXTURE9 miniShape[maxMini];LPDIRECT3DTEXTURE9 composite[8];D3DVIEWPORT9 viewData;D3DVIEWPORT9 smallView = {816,112,64,64,0.0f,1.0f};LPD3DXFONT dxfont;int vpRed = 0x00, vpBlue = 0x00, vpGreen = 0x00;long xPos = 0, yPos = 0;bool initialRun = false;int miniPos = 0;void loadLayout();void drawLayout();void drawComp();void initD3D(HWND hWnd);void render_frame(void);void cleanD3D(void);void initDInput(HINSTANCE hInstance, HWND hWnd);void detect_keys(void);//void detect_mousepos(void);void leftMouse();void clearDInput(void);LRESULT CALLBACK WindowProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam);int WINAPI WinMain(HINSTANCE hInstance,   HINSTANCE hPrevInstance,   LPSTR lpCmdLine,   int nCmdShow){HWND hWnd;WNDCLASSEX wc;ZeroMemory(&wc, sizeof(WNDCLASSEX));wc.cbSize = sizeof(WNDCLASSEX);wc.style = CS_HREDRAW | CS_VREDRAW;wc.lpfnWndProc = (WNDPROC)WindowProc;wc.hInstance = hInstance;wc.hCursor =LoadCursor(NULL, IDC_ARROW);wc.hbrBackground = (HBRUSH)COLOR_WINDOW;wc.lpszClassName = L"WindowClass";RegisterClassEx(&wc);hWnd = CreateWindowEx(NULL,  L"WindowClass",  L"d3d window",  WS_OVERLAPPEDWINDOW,  100, 100,  SCREEN_WIDTH, SCREEN_HEIGHT,  NULL,  NULL,  hInstance,  NULL);ShowWindow(hWnd, nCmdShow);initD3D(hWnd);initDInput(hInstance, hWnd);MSG msg;
