MFC中添加按钮和文本框

#include <stdio.h>
#include <windows.h>

LRESULT CALLBACK WinSunProc(
HWND hwnd, // handle to window
UINT uMsg, // message identifier
WPARAM wParam, // first message parameter
LPARAM lParam // second message parameter
);

int WINAPI WinMain(
HINSTANCE hInstance, // handle to current instance
HINSTANCE hPrevInstance, // handle to previous instance
LPSTR lpCmdLine, // command line
int nCmdShow // show state
)
{
WNDCLASS wndcls;
wndcls.cbClsExtra=0;
wndcls.cbWndExtra=0;
wndcls.hbrBackground=(HBRUSH)GetStockObject(LTGRAY_BRUSH);
wndcls.hCursor=LoadCursor(NULL,IDC_ARROW);
wndcls.hIcon=LoadIcon(NULL,IDI_APPLICATION);
wndcls.hInstance=hInstance;
wndcls.lpfnWndProc=WinSunProc;
wndcls.lpszClassName="DNA_Random";
wndcls.lpszMenuName=NULL;
wndcls.style=CS_HREDRAW | CS_VREDRAW;
RegisterClass(&wndcls);

CButton button();

HWND hwnd;
hwnd=CreateWindow("DNA_Random","DNA",WS_OVERLAPPEDWINDOW,
0,0,600,400,NULL,NULL,hInstance,NULL);

ShowWindow(hwnd,SW_SHOWNORMAL);
UpdateWindow(hwnd);

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

LRESULT CALLBACK WinSunProc(
HWND hwnd, // handle to window
UINT uMsg, // message identifier
WPARAM wParam, // first message parameter
LPARAM lParam // second message parameter
)
{
switch(uMsg)
{
case WM_PAINT:
HDC hDC;
PAINTSTRUCT ps;
hDC=BeginPaint(hwnd,&ps);
EndPaint(hwnd,&ps);
break;
case WM_CLOSE:
if(IDYES==MessageBox(hwnd,"是否真的结束？","weixin",MB_YESNO))
{
DestroyWindow(hwnd);
}
break;
case WM_DESTROY:
PostQuitMessage(0);
break;
default:
return DefWindowProc(hwnd,uMsg,wParam,lParam);
}
return 0;
}
这段程序会显示一个窗口，现在想在这个窗口里添加按钮和文本框，怎么写代码啊？

你这根本不是MFC编程，而是windows32编程，如果是MFC编程方式会方便一些；
你又在窗口过程（WinSunProc）中处理WM_CREATE消息；当产生此消息时，用CreateWindow函数来创建按钮盒文本框；关于如何用CreateWindow创建按钮盒文本框可以参考CreateWindow的使用，关键要设置第一个参数；要设置正确的窗口类，系统为诸如按钮、编辑框、文本框等通用控件预定义了窗口类，可查一些联机帮助。
