1、加載位圖
2、建立兼容DC
3、選擇之前的位圖對象
4、用貼圖函數(shù)BitBlt()
HBITMAP bitmap=(HBITMAP)LoadImage(NULL,L"Name.bmp",IMAGE_BITMAP,high,length,LR_LOADFROMFILE); HWND tmp=CreateCompatiable(g_hdc); SelectObject(tmp,bitmap); BitBlt(g_hdc,0,0,high,length,tmp,0,0,SRCCOPY);
Demo完整代碼:
#include <windows.h> #include <time.h> const int TAR_HIGH=800; const int TAR_WEIGHT=600; const wchar_t TAR_TITLE[]=L"致我們不磨滅的青春和理想-建大英雄傳"; HDC g_hdc=NULL; HDC g_mdc=NULL; HBITMAP g_hbitmap=NULL; void Game_Paint(HWND hwnd) { SelectObject(g_mdc,g_hbitmap); BitBlt(g_hdc,0,0,TAR_HIGH,TAR_WEIGHT,g_mdc,0,0,SRCCOPY); } bool Game_Init(HWND hwnd) { g_hdc=GetDC(hwnd); //在這里做初始化工作 g_hbitmap=(HBITMAP)LoadImage(NULL,L"content.bmp",IMAGE_BITMAP,TAR_HIGH,TAR_WEIGHT,LR_LOADFROMFILE); //建立DC g_mdc=CreateCompatibleDC(g_hdc); Game_Paint(hwnd); ReleaseDC(hwnd,g_hdc); return 1; } bool Game_Clear(HWND hwnd) { DeleteObject(g_hbitmap); DeleteDC(g_mdc); return 1; } LRESULT CALLBACK SdjzuProc(HWND hwnd,UINT message,WPARAM wParam,LPARAM lParam) { switch(message) { PAINTSTRUCT paintstruct; case WM_PAINT: //新增設(shè)備環(huán)境句柄調(diào)用 g_hdc=BeginPaint(hwnd,&paintstruct); Game_Init(hwnd); EndPaint(hwnd,&paintstruct); ValidateRect(hwnd,NULL); break; case WM_KEYDOWN: if(wParam=VK_ESCAPE) DestroyWindow(hwnd); break; case WM_DESTROY: PostQuitMessage(0); break; default: return DefWindowProc(hwnd,message,wParam,lParam); } return 0; } int WINAPI WinMain( __in HINSTANCE hInstance, __in_opt HINSTANCE hPrevInstance, __in LPSTR lpCmdLine, __in int nShowCmd ) { WNDCLASSEX wndclass={0}; wndclass.cbSize=sizeof(WNDCLASSEX); wndclass.style=CS_HREDRAW|CS_VREDRAW; wndclass.lpfnWndProc=SdjzuProc; wndclass.cbClsExtra=0; wndclass.cbWndExtra=0; wndclass.hInstance=hInstance; wndclass.hIcon=(HICON)::LoadImage(NULL,L"tarico.ico",IMAGE_ICON,0,0,LR_DEFAULTSIZE|LR_LOADFROMFILE); wndclass.hCursor=LoadCursor(NULL,IDC_ARROW); wndclass.hbrBackground=(HBRUSH)GetStockObject(WHITE_BRUSH); wndclass.lpszMenuName=NULL; wndclass.lpszClassName=L"sdjzuhero"; //注冊窗口 if(!RegisterClassEx(&wndclass)) return -1; HWND hwnd=CreateWindow(L"sdjzuhero",TAR_TITLE,WS_OVERLAPPED|WS_CAPTION|WS_SYSMENU|WS_MINIMIZEBOX,CW_USEDEFAULT,CW_USEDEFAULT,TAR_HIGH,TAR_WEIGHT,NULL,NULL,hInstance,NULL);//第三個參數(shù)控制了窗口的樣式，合集為WS_OVERLAPPEDWINDOW MoveWindow(hwnd,250,80,TAR_HIGH,TAR_WEIGHT,true); ShowWindow(hwnd,nShowCmd); UpdateWindow(hwnd); //載入報錯模塊 MSG msg={0}; while(msg.message!=WM_QUIT) { if(PeekMessage(&msg,0,0,0,PM_REMOVE)) { TranslateMessage(&msg); DispatchMessage(&msg); } } UnregisterClass(L"sdjzuhero",wndclass.hInstance); return 0; } 剛開始試了幾次沒有成功，發(fā)現(xiàn)是在WndProc里對函數(shù)的調(diào)用出錯了，沒有執(zhí)行init部分，改成init之后問題解決。看來與ACM一樣，不能唯別人的模板是從，還是應(yīng)該理解后加以修改，以更好的利用。
