Missing Modules in Python 3.0 will defame it. If developers will develop the modules for Python 3, it will boost it with already said modernism and others stuffs like sneekula thing. Who will go for 3k and miss those valuable modules like wxpython, and many other non standard modules??

Hello Dev,
I want to change font colour in wx.RichTextCrtl, but I find the way it is used in wxDemo is complicated with no code to explain. Is there simple way to do it? If there is no other way, can someone explain the way it is done in demo TALKally (with comments)?
Thanks alot!
Steve

Thanks HoustonIT,
I'm Going to try it out
Great!

I have not used python 3k because I'm still learning under 2.5
Anyway I will be excite for those already are playing with it to tell me what is new and what is better about 3k, which excite them Like what Gribouillis said

What error do you get friend? Can you post every angle of the problem? Can you access mysql via commandline

I have Ubuntu/Vista Multiboot. While in Ubuntu I can access all my NTFS vista partition but not vice versa. Is there a legal hacking to get vista read the ubuntu file system?

open python shell and type in:
Python 2.5.2 (r252:60911, Feb 21 2008, 13:11:45) [MSC v.1310 32 bit (Intel)]
Type "help", "copyright", "credits" or "license" for more information.
>>> import MySQLdb

if nothing happens and interpreter gives >>> then behold it is up and running othewise you will get traceback:
Traceback (most recent call last):
File "<string>", line 1, in <string>
ImportError: No module named MySQLdb

Finally solved. Codes are roughly arranged and are not in order because I was learning the bass.dll & ctypes basics

I am from India

Mhh India Leads in this!

Try something like this

f= open("test.txt", "r")
s = f.readlines()
for name in s: 
    name = name.lower()    
    if name == "steve":
        print name
        print "found name %s" %(name, )
    else:
        print name
        print "No such Name!"
        
f.close()

my friend, use code blocks when posting codes so as to preserve the most valuable indentation

My friend, I propose you start with this:

I use ctypes to play AUDIO using bass.dll found here:
http://www.un4seen.com/
I have gone so far and tried as they advised me at their forum entry here:
http://www.un4seen.com/forum/?topic=9257.0
But I still get errors. Can anyone take code and analyze to point out source of error?
Here is the code, pse ignore any useless comment, I was using the editor as scratch pad too :D

With thanks,

wxpython is exactly what you need. It looks native in the platform take a look at wxpython.org for docs and API plus zetcode.com for tutorial

check this:
http://www.greenteapress.com/thinkpython/thinkpython.pdf

Or you can use Revo Uninstaller. It hav Got special feature for startup. Also Anvir Task manager should be able to do it

take a look here:
http://zetcode.com/wxpython

http://docs.python.org/tutorial/
http://zetcode.com/tutorials/pythontutorial

Ok, does any other wxpy program run successful? I ask because may be version is wrong (I always prefer unicode). Another problem is installing wxpy with less admin rights. Try to re-install wxpy in Admin level. Try same code but compile with 2.5

so, now; what is the cause of error:
TypeError: list objects are unhashable

so you say that when created, prototype calls the required arguments? I mean, I haven't passed any arg as you can see. I have just defined it. Should I pass all the arguments before call CFUNCTYPE??

don't use a list when assigning restype: res = bass_dll.BASS_SampleLoad.restype = ct.c_int But I suspect you're in for a spot of trouble.

a FILE * is NOT a char * fname;

What do you mean?

tried but this error poped:
TypeError: list objects are unhashable

What does it try to tell me?

I'm learning ctypes right now and have made simple function and here is the code

#import ctypes module
import ctypes as ct
#get BOOL C++ value from ctypes
from ctypes.wintypes import BOOL
#Loading the DLL see: http://www.daniweb.com/forums/thread160430.html
bass_dll = ct.cdll.bass
#here is function description on the function
""" Loads a WAV, AIFF, MP3, MP2, MP1, OGG or plugin supported sample.
     HSAMPLE BASS_SampleLoad(
     BOOL mem,
         void *file,
         QWORD offset,
         DWORD length,
         DWORD max,
         DWORD flags
     );  
     
     CFUNCTYPE(restype, *argtypes)
     """
#The rguments list
res = bass_dll.BASS_SampleLoad.restype = [ct.c_int]        
args = bass_dll.BASS_SampleLoad.argtypes = [BOOL, ct.c_char_p, ct.c_int, ct.c_int, ct.c_int, ct.c_char_p]
prototype = ct.CFUNCTYPE(res, args)
print prototype

when I run I get error:
TypeError: restype must be a type, a callable, or None
I dont know what is wrong, so need help!

if wxpython, then Show(True) method is to show widgets and by default is True so you don't need to add it. figure()?? Not sure what it is! Which modules are you using?

I got it!

from ctypes.wintypes import BOOL
#then you can use BOOL anywhere in your code

What is ctypes data for BOOL?
I mean in C++ to ctypes we have:
int--> c_int
float--> c_float
what about BOOL?

have you checked those garbages? Many times these ready made PC/Laps comes with garbage of softs and you need to uninstall them manually. If you want to make it easy: Use revo uninstaller for free or Uninstaller! 2006 for $

Check for garbage programs that might be installed and startup withsystem

I suggest pure HTML for such application. Python can do it, may be check here:
http://wiki.python.org/moin/WebProgramming

break and continue might be what you need
if x==0 break --> this stops the Loop
y==1 continue --> this makes loop running

this might help:

O2 - BHO: (no name) - {A3A641C8-7F6F-470E-8328-C28717500A65} - C:\WINDOWS\system32\geBtRigg.dll

O4 - HKLM\..\Run: [nwiz] nwiz.exe /install

I susspect these programs were the stubborn ones
They are unIdentified, yet install themselves at startup :-O

okay so i have the same acer 6920 and i have the same problems basically but i cannot open an internet window? any ideas?

How did it start to misbehave? Can you provide details

? what?

I sometimes wish to shut it up (I have done some time ago) due to those annoying behaviours. What do you reckon?

Anyone who knows QWORD, DWORD and BOOL ctypes Equivalents. I find c_int, c_float etc but not the Equivalent above!

I have failed to re-write the function in python because I don't know how to convert QWORD offset, and BOOLto ctypes. Someone help me please!

I have problems with the MS updates. They sometimes cause great problems. I have recently rolled back using sys restore and Lost my Anvil Taskmanager I got from giveaway! It messed up with my HDSPA huawei E220 and my Wing IDE. It have done before and my Laptop became Unstable

I'm not sure If it is right to install it or disable completly the updates!

No problem! Misunderstanding that ends with understanding is not.....bad haaah

Not only Run, but also debug, which is missing in IDLE. There is also browser for classes and methods if you have long code. I used for sometime 101 version before I bought the personal Edition. After I master well the Language I will go for Pro version. From my point of view, 101 verion is best than many free IDE available and too superior to compare with IDLE

Dont take me at my word, do it yourself
www.wingware.com

I have started the mission!
I have already the CDs and it allows Once,
so once created, not worthy to fill my HDD
Thanks

I meant give up in the forum and not Quit the programming deal
Anyway I don't know what he mean exactly unless he explains lol:

why not use Wing IDE? It have been my IDE for python. I have tried many; SPE, Pyscripter BOA, etc and found Wing IDE both easy and Powerful. If you don't Like to pay $ there is 101 version with stripped feature but have Editor, Run/Debug, Methoda/Class browser!

I suggest it, but again it is a matter of preference!

wx.ListCtrl is the best choice in my Opinion,
as Shadwick i suggest using style flag to get thing done

Why Painful? Yes thing aren't easy but possible!
You have to state clearly everything where have you failed or what you want to do but have no Idea where to start. From there it is simple to help you! Don't give up so easily!

sample code??
Are you using TextCtrl or what?

Proportionality is missing. Also you can add wx.EXPAND for widgets to fit your sizer better

import wx

class MainWindow(wx.Frame):
	def __init__(self, parent, id, title):
		wx.Frame.__init__(self, parent, wx.ID_ANY, title, size=(400,200), style = wx.DEFAULT_FRAME_STYLE | wx.NO_FULL_REPAINT_ON_RESIZE)
		
		#-- I think you need a panel if you're going to have more than one control in your frame.
		panel = wx.Panel(self, -1)
		
		#--- Create the Username label and text box and add them to the panel
		#--- I think the TextCtrl needs to have self. at the front for the value to be used by
		#--- the Process() function below.  There must be a better way.
		
		self.txt_Username = wx.TextCtrl(panel, 1, size=(125, -1))
		lbl_Username = wx.StaticText(panel, -1, "Username:")
		
		#-- Create the Password label and text box and add them to the panel
		self.txt_Password = wx.TextCtrl(panel, 1, size=(125, -1), style=wx.TE_PASSWORD)
		lbl_Password = wx.StaticText(panel, -1, "Password:")
		
		#-- Create the processing button, add it to the panel and wire it up to a function in the class
		btn_Process = wx.Button(panel, -1, "&Process")
		self.Bind(wx.EVT_BUTTON, self.Process, btn_Process)
		
		#-- Create the close button, add it to the panel and wire it up to a function in the class
		btn_Close = wx.Button(panel, -1, "&Close")
		self.Bind(wx.EVT_BUTTON, self.onExit, btn_Close)
		
		#-- Now we have to create a grid to layout our controls
		#format--> sizer.Add(widget_to_add, proportion,spacing btn widgets )
		#Also using Flexigrid sizer use AddMany for simplicity
		sizer = wx.FlexGridSizer(rows=3, cols=2, hgap=5, vgap=10)
		sizer.Add(lbl_Username,0, wx.LEFT|wx.TOP| wx.RIGHT, 5)
		sizer.Add(self.txt_Username,0, wx.TOP| wx.RIGHT, 5)
		sizer.Add(lbl_Password,0, wx.LEFT|wx.TOP| wx.RIGHT, 5)
		sizer.Add(self.txt_Password,0, wx.TOP| wx.RIGHT, 5)
		sizer.Add(btn_Process,0, wx.LEFT|wx.TOP| wx.RIGHT, 5)
		sizer.Add(btn_Close,0, wx.TOP| wx.RIGHT, …

I have problems too in learning ctypes. They are powerful way to port C++ power into python, but seems to lack begginers tutorial which is very sad. For man like me with little knowledge in c++, it is big burded.

Anyway, so far what I know is that, in order to rightly call any function in Python using ctypes are
1. define result type using restype
2. define arguments types using argtype
3. call the function with right arguments

But so far I haven't been successful to do anything useful with ctypes. I believe sometimes I will do!

I give up...Is this problem fixed now???

which problem?
