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?
For understandable reasons, the math/CDF player is severely limited in both input and output.
However, Print works, so you could print in TableForm - 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.
Button["Press me!", Print[TableForm[RandomReal[{0, 1}, {10, 10}]]]]
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...
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:
WolframAlpha[
"QRcode:\"" <> ToString[N[Pi, 100]] <> "\"", {{"QRCodeBarcode", 1},
"Content"}]
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.
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 ?
