给你贴个小例子

#include <Windows.h>

#include <math.h>

#include <GdiPlus.h>

#pragma comment(lib,"GdiPlus.lib")

using namespace Gdiplus;

LRESULT CALLBACK WinProc(

HWND hwnd,

UINT uMsg,

WPARAM wParam,

LPARAM lParam

);

void drawbitmap(HDC hdc)

{

Graphics grap(hdc);

Image img(L"E:\\宽屏壁纸\\图片\\jiani.jpg");

grap.DrawImage(&img,0,0);

}

int WINAPI WinMain( HINSTANCE hInstance,

HINSTANCE hPrevInstance,

LPSTR lpCmdLine,

int nCmdShow

)

{

TCHAR szname[]=TEXT("classname");

HWND hwnd;

MSG msg;

WNDCLASS wndclass;

GdiplusStartupInput gdiplusStartupInput;

ULONG_PTR gdiplusToken;

// Initialize GDI+.

GdiplusStartup(&gdiplusToken, &gdiplusStartupInput, NULL);

wndclass.style= CS_HREDRAW | CS_VREDRAW;

wndclass.lpfnWndProc=WinProc;

wndclass.cbClsExtra=0;

wndclass.cbWndExtra=0;

wndclass.hbrBackground=(HBRUSH)GetStockObject(WHITE_BRUSH);

wndclass.hCursor=LoadCursor(NULL,IDC_ARROW);

wndclass.hIcon=LoadIcon(NULL,IDI_APPLICATION);

wndclass.hInstance=hInstance;

wndclass.lpszClassName=szname;

wndclass.lpszMenuName=NULL;

RegisterClass(&wndclass);

hwnd=CreateWindow(szname,TEXT("windowsnametest"),WS_OVERLAPPEDWINDOW,100,100,300,300,NULL,NULL,hInstance,NULL);

ShowWindow(hwnd,nCmdShow);

UpdateWindow(hwnd);

while(GetMessage(&msg,hwnd,0,0)>0)

{

TranslateMessage(&msg);

DispatchMessage(&msg);

}

UnregisterClass(szname,hInstance);

GdiplusShutdown(gdiplusToken);

return 1;

}

LRESULT CALLBACK WinProc(

HWND hwnd,

UINT uMsg,

WPARAM wParam,

LPARAM lParam

)

{

switch(uMsg)

{

HDC hdc;

case WM_PAINT:

hdc = GetDC(hwnd);

drawbitmap(hdc);

ReleaseDC(hwnd,hdc);

break;

case WM_CLOSE:

DestroyWindow(hwnd);

PostQuitMessage(1);

break;

default:

return DefWindowProc(hwnd,uMsg,wParam,lParam);

}

return DefWindowProc(hwnd,uMsg,wParam,lParam);

}
