Obtain the Chinese character internal code in the VC text editing box

In the past few days, I have helped a senior student build a graduation project. To implement a 5110 embedded Chinese font library, I need to write a VC window. Simply put, I need to enter a Chinese character and get its internal code, chinese character encoding is involved.

Let's talk about the Chinese character internal code, the Chinese character internal code, also known as "Chinese Character ASCII code", referred to as "Internal code", refers to the internal storage of the computer, the code used to process and transmit Chinese characters consists of 0 and 1 Symbols. After the input code is accepted, the "input code conversion module" of the Chinese character operation system is converted to the inner code, which is irrelevant to the keyboard input method used. The inner code is the most basic encoding of Chinese characters. No matter what Chinese character system or Chinese Character Input Method, the inner code of the entered Chinese characters must be converted into the inner code, to be stored and processed.

Chinese characters are unique in the computer. Because the Chinese character processing system must ensure the compatibility of Chinese and Western characters, when both the ASCII code and the Chinese character National Standard Code exist in the system, it will produce ambiguity. For example, there are two bytes of content: 30 h and 21 H. It can both represent the Chinese character "ah", and the Chinese character "0" and "!". . To this end, the Chinese character machine internal code should be properly processed and transformed.

The internal code of the GB code is a two-byte code that adds "1" to the highest bit of each byte of the corresponding GB code, that is, the internal code of the Chinese character machine = the Chinese character code + 8080 H. For example, the above-mentioned "ah" Chinese character code is 3021 h, and the Chinese character machine internal code is b0a1h.

The principle is over. How can this VC program be implemented?

It is easy to retrieve the area code and bit Code separately. You can change the location.

 

void Main_OnCommand(HWND hwnd, int id, HWND hwndCtl, UINT codeNotify)  {      switch(id)      {          case IDC_OK:                        TCHAR ps[256];          TCHAR name2[256];          unsigned short int tmp;          TCHAR t;          GetDlgItemText(hwnd, IDC_EDIT1, ps, sizeof(ps));              t=*ps;          *ps=*(ps+1);          *(ps+1)=t;          tmp=*(short int*)ps;          itoa(tmp,name2,16);          //wsprintf(name2, "%d", tmp);          SetDlgItemText(hwnd, IDC_EDIT2, name2);                        break;          default:          break;      }  }
