Associating filetypes with my application

Simon_Kagwi · May 29, 2007, 3:43pm

Hi,

I have created an exe from a wxPython application. I some files created using
pickle and I want them to be opened in my application when double-clicked. Is
this possible?

By the way, how can I allocate an icon to those files?

[I am using wxPython 2.8 and Python 2.4 on XP Pro]

Regards,

Simon.

Hi all,
I have a problem that couldn't solve for days, and I hope get some help
here: I have two combo box, say ComboBox1 and ComboBox2. There are two items
in ComboBox1, say "0" and "1". How can I make ComboBox2 show 8 items if
ComboBox1.Item="0" and make ComboBox2 show 16 items if ComboBox1.Item="1"?

Thanks in advance.

Hi Song,

Hi all,

in ComboBox1, say "0" and "1". How can I make ComboBox2 show 8 items if
ComboBox1.Item="0" and make ComboBox2 show 16 items if ComboBox1.Item="1"?

Something along these lines might work:

self.ComboBox1 = ComboBox1
self.ComboBox2 = ComboBox2

self.ComboBox1.Bind(wx.EVT_COMBOBOX, self.OnComboBox)

def OnComboBox(self, event):

self.ComboBox2.Clear()

    if event.GetString() == '0':
        theStrings = EightItemsList
    else:
        theStrings = SixteenItemsList

self.ComboBox2.AppendItems(theStrings)

HTH.

Andrea.

Look into packing your application with the wonderful tool called “inno setup”. You can read about the tool here:
http://www.jrsoftware.org/isinfo.php

and how to associate files during install here:

use python's _winreg module.

e.g.

import _winreg as reg

reg.CreateKey(reg.HKEY_CLASSES_ROOT,'.lpj')
reg.SetValue(reg.HKEY_CLASSES_ROOT, '.lpj', reg.REG_SZ, 'peak-o-mat')
pom = reg.CreateKey(reg.HKEY_CLASSES_ROOT, 'peak-o-mat')
ico = reg.CreateKey(pom, 'DefaultIcon')
reg.SetValue(pom, 'DefaultIcon', reg.REG_SZ, iconpath)
sh = reg.CreateKey(pom, 'shell')
op = reg.CreateKey(sh, 'open')
cmd = reg.CreateKey(op, 'command')
reg.SetValue(op, 'command', reg.REG_SZ, '\"%s\" \"%%1\"'%batchpath)

This will register '.lpj' file extension with an application called 'peak-o-mat'
and assign a default icon.

Hi

The advantage of using Inno Setup to generate an installer that does this is that it also generates an uninstaller which removes the registry changes done during the install. And it looks really nice as well…

use python’s _winreg module.

e.g.

import _winreg as reg

reg.CreateKey(reg.HKEY_CLASSES_ROOT,‘.lpj’)
reg.SetValue
(reg.HKEY_CLASSES_ROOT, ‘.lpj’, reg.REG_SZ, ‘peak-o-mat’)
pom = reg.CreateKey(reg.HKEY_CLASSES_ROOT, ‘peak-o-mat’)
ico = reg.CreateKey(pom, ‘DefaultIcon’)
reg.SetValue(pom, ‘DefaultIcon’, reg.REG_SZ, iconpath)
sh = reg.CreateKey(pom, ‘shell’)
op = reg.CreateKey(sh, ‘open’)
cmd = reg.CreateKey(op, ‘command’)
reg.SetValue(op, ‘command’, reg.REG_SZ, ‘"%s" "%%1"’%batchpath)

This will register ‘.lpj’ file extension with an application called ‘peak-o-mat’
and assign a default icon.

interesting, didn't know about this.

reg.CreateKey(reg.HKEY_CLASSES_ROOT,'.lpj')
reg.SetValue(reg.HKEY_CLASSES_ROOT, '.lpj', reg.REG_SZ, 'peak-o-mat')

sh = reg.CreateKey(pom, 'shell')
op = reg.CreateKey(sh, 'open')

reg.SetValue(op, 'command', reg.REG_SZ, '\"%s\" \"%%1\"'%batchpath)

Have you tested this on Vista? I think it would only work if the application runs as admin, or it might write it to a virtualized area (I think this depends on the manifest file you use).

True. Though if you pack your software with distutils using

python setup.py bdist_wininst --install-script=<install_script>

then <install_script> is run with first argument '-install' or '-uninstall'
depending on wether you're installing the package or requesting its removal. So
you can have the same automatism.
