There are several ways to create control arrays in VC++.

  1. Using a regular C++ array, you can declare an array of pointers to controls, then use a loop to create each control individually and store it in the array.
#include <Windows.h>
#include <vector>

HWND hButtons[5];  // 控件指针数组

for (int i = 0; i < 5; i++) {
    hButtons[i] = CreateWindowEx(0, L"BUTTON", L"Button", WS_VISIBLE | WS_CHILD, 
        10 + i * 100, 10, 80, 30, hWnd, NULL, hInstance, NULL);
}
  1. You can use std::vector to store control pointers, allowing for dynamic addition and removal of controls.
#include <Windows.h>
#include <vector>

std::vector<HWND> hButtons;  // 控件指针向量

for (int i = 0; i < 5; i++) {
    HWND hButton = CreateWindowEx(0, L"BUTTON", L"Button", WS_VISIBLE | WS_CHILD, 
        10 + i * 100, 10, 80, 30, hWnd, NULL, hInstance, NULL);
    hButtons.push_back(hButton);  // 添加控件指针到向量
}
  1. Utilize dynamic arrays: Control pointers can be dynamically saved using the new operator to allocate arrays.
#include <Windows.h>

HWND* hButtons = new HWND[5];  // 动态数组

for (int i = 0; i < 5; i++) {
    hButtons[i] = CreateWindowEx(0, L"BUTTON", L"Button", WS_VISIBLE | WS_CHILD, 
        10 + i * 100, 10, 80, 30, hWnd, NULL, hInstance, NULL);
}

// 使用完后记得释放内存
delete[] hButtons;

The above are several common methods, the specific choice of which method depends on the specific needs and scenarios.
