从文本框中获取文本

Question

我一直在环顾四周，尝试各种各样的事情，但我似乎无法让它发挥作用。

我想从文本框中获取文本，并在按下其中一个按钮时将其显示在弹出窗口中。有人可以让我知道如何从文本框中获取文本吗？

#include <windows.h>

#define BUTTON_1    101
#define BUTTON_2    102

const char g_szClassName[] = "myWindowClass";

                HWND button1 = CreateWindowEx(NULL, "BUTTON", "Button   1",WS_TABSTOP | WS_VISIBLE | WS_CHILD | BS_DEFPUSHBUTTON, 180, 18, 100, 24, hWnd, (HMENU)BUTTON_1, NULL, NULL);
                HWND button2 = CreateWindowEx(NULL, "BUTTON", "Button 2",WS_TABSTOP | WS_VISIBLE | WS_CHILD | BS_DEFPUSHBUTTON, 180, 48, 100, 24, hWnd, (HMENU)BUTTON_2, NULL, NULL);
        }
    break;
    case WM_COMMAND:
