如何解决非常感谢！我的项目快完成了

我有一个 c 程序，我应该向它添加接口。我可以使用 WIn32 将我的代码插入到我的编码界面吗？

示例：这是我将二进制转换为八进制的代码。

 void biTodec(){


 long long n;
 int dec = 0,i = 0,rem;
 printf("Enter a binary number: ");
 scanf("%lld",&n);
 while (n != 0) {
    rem = n % 10;
    n /= 10;
    dec += rem * pow(2,i);
    ++i;
 }
 printf("%lld in binary = %d in decimal",n,dec);
  return 0;
 }

现在，当单击执行转换时，我希望我的按钮在我的 API 中。这是我的 Win32 设计

  #include <stdio.h>
 #include <conio.h>
 #include <windows.h>
 #include <stdlib.h>

 LRESULT CALLBACK WindowProcedure(HWND,UINT,WParaM,LParaM);

 void AddMenus(HWND);
 void AddControls(HWND);

 HMENU hMenu;



  int WINAPI WinMain(HINSTANCE hinst,HINSTANCE hPrevInst,LPSTR 
 args,int 
  ncmdshow){



  WNDCLASSW kim = {0};
  kim.hbrBackground = (HBrush)COLOR_BACKGROUND;
  kim.hCursor = LoadCursor(NULL,IDC_ARROW);
  kim.hInstance = hinst;
  kim.lpszClassName = L"myWindowClass";
  kim.lpfnWndProc = WindowProcedure;

  if(!RegisterClassW(&kim))
    return -1;

  CreateWindowW(L"myWindowClass",L"Number System Converter",WS_OVERLAPPEDWINDOW | WS_VISIBLE,100,500,NULL,NULL);
 MSG msg={0};
 while(GetMessage(&msg,NULL)){
    TranslateMessage(&msg);
    dispatchMessage(&msg);

  }
  return 0;
   }


 LRESULT CALLBACK WindowProcedure(HWND hWnd,UINT msg,WParaM 
 wp,LParaM lp){

  switch(msg){

 case WM_COMMAND:


    switch(wp){
    case 1:
        MessageBoxA(hWnd,"This project was made by bla bla for 
    seven (7) days. He had no any prior idea on interface so he spent 
  the 6 out of 7 days just for researching. copyright 2021","About 
  the 
  project",NULL);

        break;
    case 2:
        MessageBeep(MB_OK);
        break;
    case 3:
        PostQuitMessage(0);
        break;
    case 4:
        MessageBeep(MB_OK);
        break;
    case 5:
        MessageBeep(MB_OK);
        break;
    }
  case WM_CREATE:
    AddMenus(hWnd);
    AddControls(hWnd);
    break;

  case WM_DESTROY:
    PostQuitMessage(0);
    break;

  default:
    return DefWindowProcW(hWnd,msg,wp,lp);

  }
  }
  void AddMenus(HWND hWnd){
  hMenu = CreateMenu();
   HMENU hFileMenu = CreateMenu();
   HMENU hSubMenu = CreatePopupMenu();

   AppendMenu(hSubMenu,MF_STRING,4,"File");
   AppendMenu(hSubMenu,5,"Folder");
   AppendMenu(hSubMenu,MF_SEParaTOR,NULL);

   AppendMenu(hFileMenu,MF_POPUP,(UINT_PTR)hSubMenu,"Open");
   AppendMenu(hFileMenu,2,"Save");
   AppendMenu(hFileMenu,NULL);
   AppendMenu(hFileMenu,3,"Exit");

   AppendMenu(hMenu,(UINT_PTR)hFileMenu,"Options");
  AppendMenu(hMenu,1,"Help");


   SetMenu(hWnd,hMenu);
  }

  void AddControls(HWND hWnd){
CreateWindowW(L"Static",L"Choose the number system to be converted",WS_VISIBLE|WS_CHILD,30,300,20,hWnd,NULL );

  CreateWindowW(L"Edit",L"",WS_VISIBLE|WS_BORDER| WS_CHILD,60,80,120,NULL);
CreateWindowW(L"Button",L"Generate",WS_VISIBLE|WS_BORDER|WS_CHILD,200,NULL);
CreateWindowW(L"Edit",NULL);

CreateWindowW(L"Button",L"Binary",WS_VISIBLE|WS_BORDER|WS_CHILD|BS_RAdioBUTTON|WS_TABSTOP,150,L"Decimal",180,L"Octal",210,L"Hexadecimal",240,NULL);

   CreateWindowW(L"Button",NULL);
  CreateWindowW(L"Button",WS_VISIBLE|WS_BORDER|WS_CHILD|BS_RAdioBUTTON | WS_TABSTOP,NULL);

  }

是否可以将我的代码插入到 API 中？如果没有，您能建议我在我的程序中创建用户界面需要学习什么吗？

解决方法

我已经修复了您的代码并插入了您的转换功能。我没有添加更多的转换 - 你可以用我的例子自己做 - 我也没有添加增强功能。

要修复 Windows API 部分，请注意我有：

为控件保存了所有 HWND 以便能够获取/设置值。

使用 BS_AUTORADIOBUTTON 和 WS_GROUP 以便单选按钮照常工作。

为所有控件使用标识符，以便能够检查请求的是哪个操作。

使用适当的强制转换修复了各种警告。
