【AT91SAM9261试用体验】简单的WindowsCE程序HelloWorld

开发环境搭建好了，就可以从最基本的开始学起了，现在就来实现一个最简单的WindowsCE程序HelloWorld。

1、打开VS2005，新建一个智能设备项目，模板选择WIN32智能设备项目，输入文件名HelloWorld，点击下一步，选择EEIC08SDK平台，创建一个空项目。

实现一个对话框程序，需要5个基本步骤：a、创建窗体类；b、注册窗体类；c、创建窗体；d、更新显示窗体内容；e、获取系统消息。

需要两个基本函数：winmain主函数和消息处理函数。

2、在解决方案资源管理器中右键点击源文件，选择添加新建项，新建一个HelloWorld.cpp文件。添加源代码如下：

#include
#include
#include "board.h"

struct decodeinit MinMessageProc[]={
WM_DESTROY,OnDestroy,
WM_PAINT,OnPaint,
};
LRESULT CALLBACK WndProc(HWND hwnd,UINT message ,WPARAM wParam,LPARAM lParam);

int WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPWSTR lpCmdLine,
int nShowCmd)

{


WNDCLASS ws;
ws.cbClsExtra = 0;
ws.cbWndExtra = 0;
ws.hbrBackground = (HBRUSH(GetStockObject(WHITE_BRUSH)));
ws.hCursor = NULL;
ws.hIcon = NULL;
ws.hInstance = hInstance;
ws.lpfnWndProc = WndProc;
ws.lpszClassName = TEXT("Hello");
ws.lpszMenuName = NULL;
ws.style = CS_VREDRAW | CS_HREDRAW;


if(!RegisterClass(&ws)) return -1;


HWND hwnd = CreateWindow(TEXT("Hello"),TEXT("MyFirstWindows"),WS_VISIBLE | WS_BORDER | WS_SYSMENU | WS_MINIMIZEBOX | WS_MAXIMIZEBOX | WS_CAPtiON ,10,10,200,150,
NULL,NULL,hInstance,NULL);


UpdateWindow(hwnd);
ShowWindow(hwnd,nShowCmd);

MSG msg;

while(GetMessage(&msg,NULL,0,0))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}

return 1;
}

LONG OnDestroy(HWND hwnd,UINT message,WPARAM wParam,LPARAM lParam)
{
PostQuitMessage(1);
return TRUE;
}

LONG OnPaint(HWND hwnd,UINT message,WPARAM wParam,LPARAM lParam)
{
PAINTSTRUCT ps;
HDC hdc;
RECT rect;

GetClientRect(hwnd,&rect);
hdc = BeginPaint(hwnd,&ps);
DrawText(hdc,TEXT("helloWorld"),-1,&rect,DT_VCENTER | DT_CENTER);
EndPaint(hwnd,&ps);

return 0;

}

LRESULT CALLBACK WndProc(HWND hwnd,UINT message ,WPARAM wParam,LPARAM lParam)
{
for(int i = 0;i {
if(MinMessageProc.message == message)
{
MinMessageProc.fun(hwnd,message,wParam,lParam);
}
}
return DefWindowProc(hwnd,message,wParam,lParam);
/*switch (message)
{
case WM_DESTROY:
OnDestroy(hwnd,message,wParam,lParam);
break;
case WM_PAINT:
OnPaint(hwnd,message,wParam,lParam);
break;
default:
DefWindowProc(hwnd,message,wParam,lParam);

}
return 0;*/
}
3、右键点击头文件，添加新建项，新建board.h。输入如下代码：

struct decodeinit{
UINT message;
LONG (*fun)(HWND hwnd,UINT message,WPARAM wParam,LPARAM lParam);
};

#define dim(x) (sizeof(x)/sizeof(x[0]))

LONG OnPaint(HWND hwnd,UINT message,WPARAM wParam,LPARAM lParam);
LONG OnDestroy(HWND hwnd,UINT message,WPARAM wParam,LPARAM lParam);
4、编译调试，通过USB数据线连接到开发板。最终实现效果如下：
