Are you saying, that it depends on whether you have to manually call some compiler? Thats the way the term 'script' is usually used in the UNIX/Linux world. In that environment you'd call awk and Perl scripting languages but C and Java are known as compiled languages. The size of the source isn't relevant: if you can mark a source file as executable and simply run it its a 'script' while if it needs a separate preparatory step to generate a separate executable its just a source file for a compiled language. The distinction doesn't seem to be used in a Windows environment. Indeed, it doesn't make sense there since executables are limited to .BAR or .CMD files, which are directly interpreted by the command processor, and .EXE or .COM files, which must be compiled before they can be run. AFAIK there's no way you can mark anything else, such as an awk, Perl or Python source file, as executable since there is no 'executable' attribute in any Windows filing system. Not in the file system, but in the environment it is definitely possible. One might try http://www.google.de/search?q=pathext or just have a look at http://wiki.tcl.tk/1785 (the respective filetype has to be associated with it's interpreter however for this method to work.)

wxpython 2.8 -- timing and latency issues when displaying widgets
Dear all,
in an application window (subwindow of a Notebook-control) I'm trying to
do the following:
1. Create a StaticText control kind of "Please wait until processing has
finished"
2. Do some processing (e.g. vacuuming an sqlite database)
3. Create a 2nd StaticText control with the message "processing finished"
Naïvely I would expect following behavior:
1st control appears
data processing step runs
after finishing processing the 2nd control appears
but actually the order in execution seems to be a different one:
computer is doing heavy processing
1st control appears
2nd control appears immediately after the 1st without any visible delay
Could someone give a hint, how to change the seeming behavior into the
intended one?
Thanks in advance Josef
P.S.:
here is the actual code snippet:
def OnVacuum(self,event):
panel=Ntab(self.desktop,"Compact")
message1=wx.StaticText(panel,-1,"Please wait, database is being
compacted.",(20,10))
self.SetCursor(wx.StockCursor(wx.CURSOR_WAIT))
con=sqlite3.connect(dbname)
cur=con.cursor()
cur.execute("VACUUM;")
cur.close()
con.close()
self.SetCursor(wx.StockCursor(wx.CURSOR_DEFAULT))
message2=wx.StaticText(panel,-1,"Compacting database has now
finished",(20,30))
Ntab is a class derived from wx.Panel and a tab of the abovementioned
wx.Notebook control
