Window Programming's WIN program framework

int Apientry _tWinMain (_in_ hinstance hinstance,
_in_opt_ hinstance hPrevInstance,
_in_ LPTSTR lpCmdLine,
_in_ int nCmdShow)

The 1._twinmain function is the entry point for the program

2.MyRegisterClass registers the window class by calling this function (setting window properties, styles, callback functions, etc.)

The specific function is as follows

ATOM MyRegisterClass (hinstance hinstance)//hinstance: Application Current instance{    //struct EX represents the premium version of the WNDCLASSEX structure for registering window classesWndclassex Wcex; Wcex.cbsize=sizeof(Wndclassex); Wcex.style= Cs_hredraw | Cs_vredraw;//styleWcex.lpfnwndproc = WndProc;//indicates the function callback function addressWcex.cbclsextra =0; Wcex.cbwndextra=0; Wcex.hinstance=hinstance; Wcex.hicon=LoadIcon (hinstance, Makeintresource (Idi_win32project1)); Wcex.hcursor=loadcursor (NULL, Idc_arrow); Wcex.hbrbackground= (Hbrush) (color_window+1); Wcex.lpszmenuname=Makeintresource (IDC_WIN32PROJECT1); Wcex.lpszclassname=Szwindowclass; WCEX.HICONSM=LoadIcon (Wcex.hinstance, Makeintresource (Idi_small)); returnRegisterClassEx (&Wcex);}

It calls RegisterClassEx to complete the registration and tells the system what the window was built to grow.

3.CreateWindow Create window

int ncmdshow)

Call CreateWindow by the function above

Parameter 1: Name of the window class

Parameter 2: The name of the window

Parameter 3: You can set the style of some windows

Parameter 8: Handle to parent window

Parameter 9: Handle to Menu

Parameter 10: Initialization of a message

HWnd = CreateWindow (Szwindowclass, L"hello", Ws_overlappedwindow,      500  , NULL, NULL, HINSTANCE, NULL);

With the first parameter, Szwindowclass--The name of the window class---> To tell the System what window to create

In vs2013, you can see in the string table file

4.ShowWindow (HWnd, ncmdshow); Display window

UpdateWindow (HWND);

5. Introduction to other functions

5.1 LoadString (HINSTANCE, Idc_win32project1, Szwindowclass, max_loadstring); To get a string by loadstring

5.2 Callback function: LRESULT CALLBACK WndProc (HWND hwnd, UINT message, WPARAM WPARAM, LPARAM LPARAM)

Respond to various messages.
