Howto: Delete Rows in wx.Grid

TIPS: Python: How to convert python script to executable

Python script can be converted in a standalone executable using one of the exe builder like
* py2exe (Windows)
* py2app (Mac OS)
* PyInstaller (all platforms)
* cx_Freeze (Windows and Linux)
* bbFreeze (Windows and Linux)

creating windows service using pyinstaller

# Usage: 
# service.exe install
# service.exe start
# service.exe stop
# service.exe remove

Get the windows service state using Python

following code can be used to find if any service is installed and if so then return the state of the service.

import wmi

class servicePython():
    def __init__(self, serviceName):
        self.c = wmi.WMI ()
        self.serviceName = serviceName

    def setServiceName(self, serviceName):
        self.serviceName = serviceName

    def getStatus(self):   
        srv = c.Win32_Service (name=self.serviceName)
        if srv != []:
            return c.Status
        return False

recursive list files in a dir using Python

use the following code to list the files in a dir tree

import os
import sys
fileList = []
rootdir = sys.argv[1]
for root, subFolders, files in os.walk(rootdir):
    for file in files:
        fileList.append(os.path.join(root,file))
print fileList

Setting wx.TextCtrl readonly

Simply use the following code:

txtCtrl.SetEditable(False)

# Also its a good idea to change the backgroud colour so user will know that is has became readonly.

txtCtrl.SetBackgroundColour((255,23,23))

TIPS: WX.Python.Grid: Removing the selected Rows

lst = None
no = self.grid_ShareDetails.GetNumberRows()
lst = sorted(self.grid_ShareDetails.GetSelectedRows())
lst.reverse()
for l in lst:    
    self.grid_ShareDetails.DeleteRows(l,1)

Tips : wx.Python : Close button not working.

If the close button does not work then add the following entries

self.Bind(wx.EVT_CLOSE, self.quit)

under the __init__ function and create a new function as

def quit(self, event):
self.Destroy()

FAQ: Resolving the “ImportError: No module named decimal” Error

Error Message:

ImportError: No module named decimal

Description:

Error occurs when executable created using pyinstaller is executed which uses pymssql module

Resolution:

import decimal in the python program

If you are using pymssql module in python program and creating

making skype portable

Ever wished to execute skype from the usb drive. Here’s how you can do that.

1. Create skype folder on usb drive.
2. copy skype.exe to that folder.
3. create subfolder named data
4. create a cmd file (save it in skype folder) with the content start %~dp0skype.exe /datapath:”%~dp0data” /removable
5. run the cmd file and enjoy.

I am not sure if skype.exe adds registry on the local machine or not, will try to find that and update.

Adding TextNode in XML using python

OSElements = document.getElementsByTagName(“ABSTRACT”)
for element in OSElements:

print element.nodeValue
new = doc.createTextNode(“TESTING”)
element.appendChild(new)

Setting ColumnWidth of wx.ListView control in python

# Get the size of listView Control
w = self.lvMountPoint.GetSize()
# Set the ColumnWidth
self.lvMountPoint.SetColumnWidth(0,w[0] * 0.81)
self.lvMountPoint.SetColumnWidth(1,w[0] * 0.19)

Get Text from multi column ListBox in Python

y = self.listCtrl.GetItem(a,n)
txt = y.GetText()

where  a =  Row Number n = Column Number

Few TK form tricks in Python.

1. Disable max button:

root.overrideredirect(0)

2. Remove all the decorations :

root.overrideredirect(1)

3. Disable Resize:

root.resizable(0,0)
