The market research has been going well and in our favour. We used a survey and interviews (blind for the first half to get opinions about the field and open the second half to get opinions about our product). We certainly have a strong market here.
And the development is going well though I have been stuck a lot on importing data. However, the tool is extremely flexible and useful - and it's great for merging data from different sources into one unified dataset which is something I think advanced users will appreciate.
I have also been trying to work on the interactive results without too much luck and have instead asked the opinions of the very knowledgeable people on the wxPython mailing list. They seem to come up with extremely helpful answers, but why not ask here?
My situation is this: I have a wxHTML frame displaying HTML results. These need to be dynamic - users will be able to select options that will mean the HTML needs to be changed and then redisplayed. The best way I can think of dealing with this is just to get the HTML (stored in a temporary memory file system) and remove the old code and insert the new code in its place and then re-display it. Does this seem like too much of a bad hack?
