C Language Implementation interface (without mfc\ to avoid forgetting)

I feel MFC does not belong to the programmer scrutiny things, this implementation of the basic interface to avoid future forgetting.

Source:

#include <windows.h>
#include <stdio.h>
Char str[] = {' 0 '};
Char cmd[] = {' 0 '};
Char hour[10], minute[10];
int num;
int Num_text_hour, Num_text_minute;
Char num_str[];
LRESULT CALLBACK WndProc (Hwnd,uint,wparam,lparam);
int WINAPI WinMain (hinstance hinstance,hinstance hprevinstance, LPSTR lpcmdline,int ncmdshow)
{
HWND hwnd;
MSG msg;
Wndclass Wndclass;

Wndclass.lpfnwndproc=wndproc;

wndclass.cbwndextra=0;
Wndclass.hinstance=hinstance;
Wndclass.hicon=loadicon (null,idi_application);
Wndclass.hcursor=loadcursor (Null,idc_arrow);
Wndclass.hbrbackground= (Hbrush) getstockobject (White_brush);
Wndclass.lpszmenuname=null;
Wndclass.lpszclassname= "Hello Win"; Window class name
Registration window
if (! RegisterClass (&wndclass))
{
MessageBox (NULL, "Window registration failed!", "Hello Win", 0);
return 0;
}
Create window
Hwnd=createwindow ("Hello Win", "Timed shutdown--junmuzi", Ws_overlappedwindow, Cw_usedefault, Cw_usedefault, Cw_usedefault, CW_ Usedefault, NULL, NULL, HINSTANCE, NULL);
Display window
ShowWindow (hwnd,ncmdshow);
Update window
UpdateWindow (HWND);
Enter the message loop: When the message picked up from the application message queue is Wm_quit, the loop is rolled out
while (GetMessage (&msg,null,0,0))
{
TranslateMessage (&AMP;MSG); converting keyboard messages
DispatchMessage (&AMP;MSG); Distributing messages
}
return msg.wparam;
