C language Create Windows window instance _c language

Can withstand loneliness, can not resist the temptation, this is the process of life

Steps:
1. Define various variables in the WinMain
2. Registration window class RegisterClass
3. Create Window CreateWindow
4. display window and Update window

Copy Code code as follows:

ShowWindow (hwnd, icmdshow);
UpdateWindow (HWND);

5. Message loop

Copy Code code as follows:

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

Complete code:

Copy Code code as follows:

#include <windows.h>

Lresult CALLBACK MyProc (HWND hwnd,uint message,wparam wparam,lparam);

int WINAPI WinMain (hinstance hinstance, hinstance hprevinstance, LPSTR lpcmdline, int nshowcmd)
{
MSG msg;
HWND hwnd;
Static TCHAR szappname[] = "HL";

Wndclass Wndclass;
Wndclass.style = Cs_hredraw | Cs_vredraw;
Wndclass.cbclsextra = 0;
Wndclass.cbwndextra = 0;
Wndclass.lpfnwndproc = MyProc;
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= Szappname;

if (! RegisterClass (&wndclass))
{
MessageBox (Null,text ("error"), TEXT ("title"), Mb_iconerror);
return 0;
}
hwnd = CreateWindow (Szappname,
TEXT ("Hello"),
Ws_overlappedwindow,
Cw_usedefault,
Cw_usedefault,
Cw_usedefault,
Cw_usedefault,
Null
Null
HINSTANCE,
Null
);
ShowWindow (Hwnd,nshowcmd);
UpdateWindow (HWND);

while (GetMessage (&msg,hwnd,0,0))
{
TranslateMessage (&AMP;MSG);
DispatchMessage (&AMP;MSG);
}
return msg.wparam;
}

Lresult CALLBACK MyProc (HWND hwnd,uint message,wparam Wparam,lparam)
{

Switch (message)
{
Case Wm_destroy:
PostQuitMessage (0);
return 0;
}
return DefWindowProc (Hwnd,message,wparam,lparam);
}
