我正在尝试在我的窗口内放置一个小输入框，该窗口目前是一个黑色的窗口。

我的代码如下，谁能告诉我如何将输入框输入到窗口中，谢谢

"#include <windows.h>

 LRESULT CALLBACK WindowProcedure (HWND, UINT, WPARAM, LPARAM);

  /*  Make the class name into a global variable  */

调用CreateWindowEx()withL"EDIT"作为窗口类名，主窗口作为父窗口。您可能还需要指定 X 和 Y 位置（不仅仅是 pass CW_USEDEFAULT），否则文本框可能不会显示。
