I like Foxit Reader very much. It’s fast, small and give you pretty much everything you need for a PDF Reader. Although they have the Linux version, I don’t really like it because I don’t seem to be able to automatically open a PDF file with a single click from Nautilus (although I already set ReaderLinux as the default Application).

Before we proceed, I am assuming you already have Wine up & running, and have installed the Windows version of Foxit Reader. What we need to do next is to associate the PDF file to Foxit Reader through Wine in Nautilus (or other File Manager that you have). If you have not install Wine, you could read the tutorial HERE.

After you have Wine up and running, download the Windows version of Foxit Reader HERE. Install it using the default settings.

First save the following script as foxit.sh in your home directory

#!/bin/bash
# Purpose: To convert Linux-style filename to Windows-style to pass as an argument
# to wine when starting Foxit Reader
Filename="z:"${1//\//\\}
#assuming you use the default installation folder for Foxit in Wine
App='eval wine "C:\Program Files\Foxit Software\Foxit Reader\Foxit Reader.exe" "'$Filename'"'
$App

Use foxit.sh as the Default Application for PDF File (select any PDF file in Nautilus, Right-Click -> Properties -> Open With -> Click [+ Add] Button -> Browse for foxit.sh located in your home folder.

Voila! Foxit Reader is now the default application for your PDF documents.

I am officially leaving Windows realm, and forced myself into the unfamiliar territory of Ubuntu Linux. Here are the list of things that I must get them running immediately, or my life will suffer :P.

1. E-Donkey Client. You can use aMule for connecting to ED2K network
2. BitTorrent Client. Azureus have a version that runs in Ubuntu. But emulating uTorrent through Wine also not bad.
3. PeerGuardian for Linux. We have MoBlock, but it doesn’t offer a GUI interface. I believe a GUI development is in progress.
4. Integrated Development Environment (IDE). So far I’m sticking myself to Eclipse for Java. WxGlade for my Python Form Designer. And Eric for Python.
5. and many more … (frankly there are thousands of pages out there offering help on running Ubuntu)

Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation=”true”/> in configuration or <%@ Page EnableEventValidation=”true” %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.

Event validation is a security measure by ASP.NET to prevent Injection-Attack (i.e. other page post their result to your ASPX page). Turning this option off through the web.config or inside the <%@ Page .. %> tag will guarantee you will never receive above error, but your security might be compromised.

But if your page still producing above error, say when you click a button, or select the value of a server dropdownlist control, these conditions might be applicable to your ASPX page:

1. You have another <form /> tag inside your main Form tag
2. Your AJAX/Javascript code changed the value of a server control
3. You type tags that resemble HTML tags inside a textbox/text-area

What I have today was number 1. I found a <form /> tag inside a < asp:Content .. /> tag. The error came out when I convert my ASP.NET Website project into .NET Web Application Project. So its quite surprising that page never throw any Event validation error during its tenure as Website project. Another possibility is the <form /> was generated by Visual Studio when i convert the project. I’ll do some trial and error more tomorrow…
