【红烧小鲫鱼】关于在纯C语言中的Shell_NotifyIcon应用

有如下代码，可以运行，但是程序会崩溃，有些地方我不会设置。

求如何设置，要用纯C语言的哦！

// HELLO.cpp : Defines the entry point for the application.

//

#include "resource.h"

#include

#define MYWM_NOTIFYICON WM_USER+1

LRESULT CALLBACK WndProc (HWND, UINT, WPARAM, LPARAM);

}

else if(WM_RBUTTONDOWN == lParam)

{

MessageBox (hwnd, TEXT("     打开hello对话框      "), TEXT("标题"), MB_OK);

}

}

case WM_CREATE:

//dwMessage = NIM_ADD;

lpdata.cbSize = (DWORD)sizeof(NOTIFYICONDATA);

lpdata.hWnd = hwnd;        //这个句柄的设置其实我觉得是错误的。

lpdata.uFlags = NIF_MESSAGE | NIF_ICON | NIF_TIP;

lpdata.uCallbackMessage = MYWM_NOTIFYICON ;

lpdata.uID = IDI_ICON1;

lpdata.hIcon = LoadIcon(((LPCREATESTRUCT)lParam)->hInstance, MAKEINTRESOURCE(IDI_ICON1));

strcpy(lpdata.szTip, "系统托盘示例");

Shell_NotifyIcon(NIM_ADD, &lpdata);

//MessageBox (hwnd, TEXT("     打开hello对话框      "), TEXT("标题"), MB_OK);

}

case WM_PAINT:

{

hdc = BeginPaint (hwnd, &ps);

GetClientRect (hwnd, &rect);

DrawText (hdc, TEXT ("Hello, Windows NT !"), -1, &rect,

DT_SINGLELINE | DT_CENTER | DT_VCENTER);

EndPaint (hwnd, &ps);

return 0;

}

case WM_SYSCOMMAND :

{

if(SC_MINIMIZE == wParam)

{

ShowWindow (hwnd, SW_HIDE);

}

return 0;

}

case WM_DESTROY:

{

PostQuitMessage (0);

return 0;

}

}

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

}

求指教。
