Library specifies the library file to be linked when the program is linked. You can set the project or use # pragma comment (Lib, "XXX. lib ") pre-compiled commands to implement links to the library files. Microsoft has also improved GDI and provided a class-based Application Programming Interface (GDI. This interface is intended for C/C ++ users. 1. Precautions for calling windowsapi As mentioned above, windowsapi is implemented through the dynamic

API programming: Controls in dialogbox message processing, such as editbox wm_char message, wm_paste message, ComboBox cbn_selchange message, and editbox en_change message. The sample code is as follows: // 1. Create a dialogShort showactivationdlg (hwnd hparent){Lresult LRET = 0;LRET = dialogbox (g_hinstthisdll, makeintresource (idd_dialog_activate), hparent, (dlgproc) dlgactivationproc ); Return (short) L

Controls created with the CreateWindow function, if you want to switch with the TAP key, the simplest way is: the main window has ws_ex_controlparent extension properties, the control has ws_tapstop properties.Then the most important thing is to make a judgment when dealing with the message loop : 1 while(GetMessage (msg, NULL,0,0))2 {3 if(! IsDialogMessage (hwnd, AMP;MSG))//Not the HWND, not the message.4 {5TranslateMessage (msg);6DispatchMessage (msg);7 }8 9}WI

CreateWindow can create a STAITC directly, but this static is opaque, if we set the window background to Gray_brush, then static will obviously have a white background, generally this is certainly very difficult to see.You can set a ws_ex_transparent extension property for static, and then intercept the wm_ctlcolorstatic message in the message callback function, dealing with textcolor and Bkmode, which is the text color and background mode:To set extended properties:1 SetWindowLong (hstatic,gwl_

, you can use the try...catch...finally statement to perform exception handling, which is used to catch exceptions caused by an error or to execute a throw statement. Its basic syntax is as follows:try {Here are the statements that may produce exceptions} catch (Error) {Here is the statement that is responsible for exception handling} finally {Here is the export statement}the code above attempts to create a canvas object and gets its context. If an error occurs, you can catch the error and know
