[Tutor] Read-ahead for large fixed-width binary files?

I've been writing a lot of utility programs for my clients who are users of a certain legacy database application - exporting, reporting, pretty label printing, etc. The database is normalized into 45 files, each of which contains fixed-length records (ranging from 80 bytes to 1024). A few of tho

Re: [Tutor] Read-ahead for large fixed-width binary files?

OK, I feel quite foolish... almost immediately after hitting 'send' I realized I can implement this myself, using 'read(bigsize)' - currently I'm using 'read(recordsize)'; I just need to add an extra loop around my record reads. Please disregard... On Nov 16, 2

[Tutor] Questions about wxEvents

I have a specific question - how can I generalize a FileBrowseButtonWithHistory - and I realized, as I was trying to word my question, that my real question is a bit more generic. First, the specific question: The FileBrowseButtonWithHistory requires a callback override and some custom code to st

Here's the same thing with a list instead of a dictionary: #=== class thingy(): example = "Just testing - " def __init__(self, num): self.example = self.example + str(num) thang = [] for x in range(1,4): thang.append(thingy(x)) for item,

Re: [Tutor] Choice of GUI builders

I'm using wxPython, after very brief forays into Tk and Qt, and I like it a lot. wx generally wraps the native widgets of whatever OS/desktop it runs on, and its idiom felt more comfortable to me than the others. Also, unlike Qt, it's free... I hate to be a cheapskate, but I'm a very small busines
