Saw 1 win32api programming knowledge, last night I search the Internet for many tutorials, a spruced-up version windows programming, code mangled, transcribing, translation to understand stiff, term is not professional, 1 windows. c programming, fuzzy, and using VC + + 6.0, because my computer can't vc + + 6.0, can only use vs2008, many operations and functions are not too 1 sample. Find a blog post on win32api programming on the web, copy it down, and compile it down to 10 errors... Dizzy dead.
Later, I referred to the following four steps and wrote MSDN in C language. I felt dizzy and my English was not good. In other words, kingsoft powerword translated the whole sentence of MSDN professionally.
Steps:
1. Registration window class;
2. Create forms;
3. Message loop;
4, write window message processing function.
Code:
#include <windows.h>
#include<tchar.h>
LRESULT CALLBACK WindowProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam);
int WINAPI _tWinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance, LPWSTR szCmdLine, int nCmdShow)
{
WNDCLASS wc;
wc.style = CS_HREDRAW | CS_VREDRAW;
wc.lpfnWndProc = WindowProc;
wc.cbClsExtra = 0;
wc.cbWndExtra = 0;
wc.hInstance = hInstance;
wc.hIcon = NULL;
wc.hCursor = LoadCursor(NULL,IDC_ARROW);
wc.hbrBackground = (HBRUSH)COLOR_WINDOW;//(HBRUSH)GetStockObject();
wc.lpszMenuName = NULL;
wc.lpszClassName = _T("MyWindowClass");
if (!RegisterClass(&wc))
{
MessageBox (NULL, _T(" Unable to register window class "), _T(" error "), MB_OK);
return 0 ;
}
HWND newWindow = CreateWindow(
_T("MyWindowClass"),
_T(" My first 1 a winapi The program "),
WS_OVERLAPPEDWINDOW,
0,
0,
CW_USEDEFAULT,
CW_USEDEFAULT,
NULL,
NULL,
hInstance,
NULL
);
if (NULL == newWindow)
{
MessageBox (NULL, _T(" Unable to create form "), _T(" error "), MB_OK);
return 0;
}
ShowWindow(newWindow, nCmdShow);
UpdateWindow(newWindow);
MSG msg;
while(GetMessage(&msg, NULL, 0, 0))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}
LRESULT CALLBACK WindowProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
switch (uMsg)
{
case WM_DESTROY:
{
PostQuitMessage(0);
break;
}
default :
return DefWindowProc(hwnd, uMsg, wParam, lParam);
}
return 0;
}
It is a form with only the title bar, close button, minimize button, maximize/restore button, and display area.
Written in pure C, I'm so depressed, it's so long, win32api super macro, love and hate, bored to death
