【问题描述】：
我有这段代码允许用户创建一个按钮数组，任何一个都在一个from中。 Here 和 here 是我正在做的两个示例（在 Create an account now? 点击 NO 然后下载 zip 文件）。
问题如下：
我需要保存用户所做的一切：例如，如果他添加了 5 个按钮并保存了它，那么下次当他打开保存的文件时，他会在保存它们的相同位置看到 5 个按钮。 这将允许用户将文件发送给使用相同程序的另一个人，然后其他人查看创建的文件。
由于误解（下面的cmets），我将发布一些代码，上面的第二个链接。但问题是我找不到任何代码来做我所要求的。伙计们，我什至不知道如何开始，我的意思是我知道如何从图片框或某些文本中保存图像，但按钮数组是另一回事。
这里是代码简单的示例代码或者你可以下载我贴的第二个文件并编译它。

说真的，您希望这里有人为您工作吗？

总有一些人喜欢 0xa3 "Haters" ...首先感谢编辑的部分，但我不希望任何人为我的项目工作比这更复杂所以到目前为止，它大约 9.42 Mb，我只是给出了一个 72kb 的示例代码......但这是我有库存，它就像 2 周的搜索没有运气。请不要让这篇文章成为讨论。我只是在寻求帮助。如果我问错了，或者这里问错了对不起。
-
如果您真的需要帮助，那么称呼别人的名字并不是一个好主意，尤其是如果正是这些人真正努力使您的问题一开始就可以理解。由于您对这个网站还很陌生：SO 是一个提出具体编程问题的地方，如果您在提出问题时需要帮助，我建议您阅读 tinyurl.com/so-hints。

好吧，我一开始只是觉得被你冒犯了，但我也很感激你解决了我的问题......无论如何重要的部分正是如此，我找不到任何具体的回答方式我的问题。甚至开始研究它。

如果你想知道你的帖子中有什么神奇的成分会以错误的方式惹恼人们，那就是“我需要代码而不是想法”。这听起来像是，“这是我的编程问题，请不要有人帮我写代码吗？”这不是它的工作原理。向我们展示（请在问题本身中）您尝试过的代码以及未解决的问题。
