我现在的程序中按下button键显示的是一行字，我想改为：按下button键就弹出一个简单的窗口，该如何做呢？

INT_PTR DialogBox(
  HINSTANCE hInstance,  // handle to module
  LPCTSTR lpTemplate,   // dialog box template
  HWND hWndParent,      // handle to owner window
  DLGPROC lpDialogFunc  // dialog box procedure
);

BOOL EndDialog(
  HWND hDlg,        // handle to dialog box
  INT_PTR nResult   // value to return
);
用这两个函数。

版主，不太懂用这两个函数呢，能不能给个例子我学习学习啊，谢谢啦

你能写上面的程序，这个自然不是问题啦。
用资源文件。
