#TechEd 2010

- by T

It has been another fantastic year for TechEd North America. I always love my time here. First, I have to give a huge thank you to Ineta for giving me the opportunity to work the Ineta booth and BOF’s (birds of a feather). I can not even begin to list how many fantastic leaders in the .Net space and Developers from all over I have met through Ineta at this event. It has been truly amazing and great fun!! New Orlean’s has been awesome. The night life is hoppin’. In addition to enjoying a few (too many??) of the local hurricanes in New Orleans, I have hung out with some of the coolest people Deepesh Mohnani, David Poll, Viresh, Alan Stephens, Shawn Wildermuth, Greg Leonardo, Doug Seven, Chris Willams, David Carley and some of our southcentral hero’s Jeffery Palermo, Todd Anglin, Shawn Weisfeld, Randy Walker, The midnight DBA’s, Zeeshan Hirani, Dennis Bottjer just to name a few. A big thanks to Microsoft and everyone that has helped to put TechEd together. I have loved hanging out with people from the Silverlight and Expression Teams and have learned a ton. I am ramped up and ready to take all that knowledge back to my co-workers and my community. I can not wait to see you all again next year in Atlanta!!! Here are video links to some of my fav sessions: Using MVVM Design Pattern with VS 2010 XAML Designer – Rockford Lhotka Effective RIA: Tips and Tricks for Building Effective Rich Internet Applications – Deepesh Mohani Taking Microsoft Silverlight 4 Applications Beyond the Browser – David Poll Jump into Silvelright! and become immediately effective – Tim Huckaby Prototyping Rich Microsoft Silverlight 4 Applications with MS Expression Blend + SketchFlow – David Carley Tales from the Trenches: Building a Real-World Microsoft Silvelright Line-of-Business Application – Dan Wahlin

An Epic Question "How to call a method when the page loads"

- by Arunkumar Ramamoorthy

Quite often, there comes a question in OTN, with different subjects, all meaning "How to call a method when my ADF page loads?". More often, people tend to take the approach of ADF Phase Listener by overriding before/afterPhase methods.In this blog, we will go through different options in achieving it.1. Method Call Activity as default activity in Taskflow :If the application is built with taskflows, then this is the best suited approach to take. 1.a. Calling a Data Control Method :To call a Data Control method (ex: A method in AMImpl exposed as client interface), simply Drag and Drop the method as Default Method Call Activity, then draw a control flow case from the method to your page. Once after this, drop the taskflow as region in main page. When we run the main page, the Method Call Activity would be called first, and then the page will be rendered.1.b. Calling a Method in Backing Bean: To call a method in the backing bean before pageload, we can follow the similar approach as above. Instead of binding the Method Call Activity to an action/method binding in pagedef, we bind to the method. Insert a Method Call Activity (and make it as default) from the Component Palette. Double click on to select a method to bind. This approach can also be used, to perform some action in backing bean along with calling a method Data Control (just need to add bindings code in backing bean to execute DC method). 2. Using invokeAction Executable :If the application is built with pages and no taskflows are involved, then this option can be taken into consideration.In the page definition of the page, add an invokeAction Executable and bind it to the method needed to be executed. 3. Using combination of Server and Client Listeners : If the page does not have any page definition, then to call a method in backing bean, this approach can be taken. In this, a serverListener would be added at the document level, which would be calling the method in backing bean. Along with this, a clientListener would be added with "load" type (i.e will be triggered when the page loads), which would queue a serverEvent to trigger the method. 4. Using Page Phase Listener :This should be the last resort. Care should be taken when using this approach since the Phase Listener would be called for each request sent by the client.Zeeshan Baig's blog covers this scenario.

Convert text files to excel files using python

- by Rahim Jaafar

I am working on INFORMIX 4GL programs. That programs produce output text files.This is an example of the output: Lot No|Purchaser name|Billing|Payment|Deposit|Balance| J1006|JAUHARI BIN HAMIDI|5285.05|4923.25|0.00|361.80| J1007|LEE, CHIA-JUI AKA LEE, ANDREW J. R.|5366.15|5313.70|0.00|52.45| J1008|NAZRIN ANEEZA BINTI NAZARUDDIN|5669.55|5365.30|0.00|304.25| J1009|YAZID LUTFI BIN AHMAD LUTFI|3180.05|3022.30|0.00|157.75| This text files can manually convert to excel files.But, I wanna ask, is there any script that I can use to convert .txt files to .xls files ? Hi all,now I'm already can convert text files to excell file by python using script that was given from user named Rami Helmy.A big thanks for him.But now,That script will produce more than one excell files depends on the number of '|' from the text files.Beside that,That script also can only convert one text files.I a going to convert all text files without state the name of text files.Therefore,I am looking such a way on how to this script going to: output only one excell file convert all .txt files from the directory that was given from user. output excell's file name are automaticly copied from the file name of text files. I am new in python,hopefully someone can help me to solve my problems.Thank You.. done all the task,but there was something that I'm confused.. that output excell files contains an "square" symbol like this: then, how can I ensure that there is no square symbol like that after I convert from text files to excell? thank you...
