从 CDF 播放器中获取数据
我为我的怀疑论者工作组在 Mathematica 中编写了一个程序，以测试探矿者评估通过照片向他们展示的人的状态的能力。对于空测量，我以 CDF 形式（新的 v8 可计算文档格式，旨在使用 CDF 播放器）。在我的计算机上（使用 mma）一切正常，但其他计算机无法导出数据（该程序会导出到 Excel 文件）。在阅读细则时，我发现播放器不支持导出。所以我的问题是：
有什么方法可以从 CDF-player 中获取数据吗？
For my Skeptics working group I wrote a program in Mathematica to test a dowser's ability to assess the status of persons shown to them by means of photographs. For a null measurement I distributed this document to my group's members in CDF form (the new v8 Computable Document Format, meant to be run with the CDF-player). On my computer (using mma) it all works fine, but the others can't export the data (the program does an export to an Excel file). On reading the fine print I see that the player doesn't support Export. So my question is:
Is there any way to get data out of CDF-player?

出于可以理解的原因，数学/CDF 播放器在输入和输出方面都受到严格限制。
但是，
Print可以工作，因此您可以在TableForm中打印 - 这会生成 TSV - 然后将其复制/粘贴到 Gnumeric （'因为为什么要使用 Excel？！）。我刚刚在 Gnumeric 和 OpenOffice 中对此进行了测试，效果很好。
将以下代码放入CDF文档中进行测试。
请注意，您无法编辑
输入，但您可以按下按钮并复制输出。怀疑论者团体通常是技术上相当有能力的人，这可能是一个可行的解决方案...For understandable reasons, the math/CDF player is severely limited in both input and output.
However,
Printworks, so you could print inTableForm- which produces a TSV - then copy/paste it into Gnumeric ('cause why would you use Excel?!).I just tested this in both Gnumeric and OpenOffice and it worked fine.
Put the following code into a CDF document to test.
Note that you can't edit the
Input, but you can press the button and copy the output. Skeptics groups are normally fairly technically competent people, this should probably be a workable solution...我认为我可以将我的数据编码在图片中，然后让小组成员从 CDF 文档中复制并通过电子邮件发送给我。它看起来像这样：
顶行定义数据槽，底行包含编码的数据作为颜色。但是，我发现 Outlook 会压缩电子邮件正文中的图片，因此图片会稍微模糊，从而导致数据损坏。下一步是使用更强大的代码，例如 QR 条形码。幸运的是，自上周以来，Wolfram | Alpha 能够生成 QR 条形码，如下所示：
我现在已经下载我自己安装了 CDF 播放器，它似乎也可以在 CDF 文档中工作，尽管我必须在正确处理互联网连接之前再次生成 QR 代码。不知道这是否是一个虚假的结果。
I thought that I could encode my data in a picture which I then would have the group members copy from the CDF document and email to me. It looked something like this:
The top row to define the data slots and the bottom row contains the data encoded as color. However, I found that Outlook compresses pictures placed in an email body, so you get slightly blurred pictures, and hence corrupted data. The next step was to use a more robust code like the QR barcode. Luckily, since last week Wolfram|Alpha is able to generate QR barcodes, like so:
I have now downloaded and installed the CDF-player myself and it seemed to work in a CDF document as well, though I had to generate the QR code a second time, before it handled the internet connection correctly. Don't know whether this is a spurious result.
对于版本 7，有 Mathematica Player 和 Mathematica Player Pro。该播放器是免费的，但没有导出功能。 Player Pro 需要付费，但可以导出。根据 http://www.wolfram.com/cdf-player/ CDF 播放器是Player部分的后代，我还不知道CDF相当于Player Pro，它可能还没有发布。您是否尝试写信给技术支持？
For version 7, there was Mathematica Player and Mathematica Player Pro. The Player was free, but had not Export capabilities. Player Pro required a fee, but could do export. According to http://www.wolfram.com/cdf-player/ the CDF player is descendant from Player part, and I am unaware of CDF equivalent to Player Pro yet, it might have not been released yet. Did you try writing to tech-support ?
