Visual Studio 2010 Beta 2 :: Installation Unsuccessful
I recently faced a problem while installing the newest version of Visual Studio 2010 Beta 2.
Error : “While installing the pre-requisites Visual Studio 2010 (x64). Did not make an attempt to install the rest”.
Solution : Follow along the steps in the same order
1) Uninstall the Visual Studio 2010 Beta 2, if its allowing to do so.
2) Delete the folder left back folder of Visual Studio in the Program Files(x86) folder > Microsoft Visual Studio 10.0.
3) Clean the registry using softwares like CCleaner(This is a Freeware and is good enough) or Tune-Up Utilities(Shareware)
4) While fixing (cleaning registry using the above softwares) make a back up of the registry entries you are about to clean(delete). CCleaner gives you an option to save the registry before cleaning.
5) Try installing the Software now, if it still doesn’t work uninstall all the supporting softwares(also) VS 2010 has installed for you. .NET 4 should also be uninstalled at this instance.
6) This time try installing and it should work if you followed the procedure properly.
This is not any official solution but just a solution I found working when I encountered the same problem. Feel free to comment…

Project Description
My Idea : I have taken the idea from the list of suggested Ideas by WordPress, GSoC project mentors. I want to work on the project namely “Sort by Columns”.
Sorting by columns is a very handy feature to include in WordPress.com. Whenever a user clicks on a particular column header, it will be sorted in ascending order with the respective details from other columns intact. When the user clicks for the second time, it will be sorted in descending order in the same fashion. So basically column headers (not all) will work as toggle buttons. Sorting will be done considering the paging issue. I also sent another proposal on AJAX paging to GSoC under WordPress. Please go through that idea once.
I will first explain my approach taking posts page (edit.php) as example and then become more general. When a user opens edit.php, all posts by default will be sorted in descending order of Date Modified.
This will be the order of column headers : Title > Author > Categories > Tags > Status > Comments > Date modified > Date published.
Figure 1.1
Lets say, the user is in second page, seeing his 20 to 40 posts out of his 200 posts. If he now clicks on Post column header (for example), all his 200 posts will be checked and then, the posts which will come in 20 to 40 range will be listed in ascending order. This will be done using JavaScript and AJAX. Unlike the whole page refresh I will just reload the posts list section (of course, sorted) using AJAX. Sorting can be accomplished using JavaScript. This is the basic idea of the problem.
3 more things should be considered :
- Suppose if the user clicks on Author column header, it will be sorted accordingly. If there are multiple posts from the same author, further sorting will be done on basis of Posts Column(same sequence : ascending/descending), then by Comments Column ( if required ), then by Date modified Column ( if required ) and lastly by Date published Column ( if required ). This is basically, moving from the left most column to right most column ignoring the column clicked and also the columns that are hidden using the screen options.
- After sorting the first set of 20 posts out of his 200 posts on page 1 on the basis of Post column, if the user now navigates to next set of 20 posts to page 2, the sorted list will be displayed on basis of Posts column only (that too maintaining the same sequence : ascending/descending).
- In WordPress 2.7, whenever a post is saved as a draft, we see a tag ‘Last Modified’ in the Date column. Including a new column for Date modified leaves the Date Published column for such a draft (which are just saved and yet to be published) empty. Instead of leaving it empty, I propose to fill it with the same date as in Date Modified column, with a small tag as Date Modified as shown in the above figure. This will yield a better sorting result.
As said earlier all the posts will be checked while sorting a particular column keeping the paging issue in mind.
I will also want to make column widths re-sizable if it is a good idea.
All other list-type screens can also be scripted on the similar lines expect for the change in column headings and their number.
What have you done so far with this idea : I studied the background PHP of all list-type screens from offline version of WordPress.com. I listed down all the exceptions and problems that I will face during the course of the project. I then came up with ideas presented above which are completely fool proof to the best of my knowledge. I surfed many pages on the internet to closely understand this sorting problem. I am working on AJAX hard, to be more comfortable with the project. I mimicked some of the features of Gmail.com, like the autocomplete & pop-up window using AJAX. All this has given me enough experience and skill to work on this project.
This can be implemented in the core patch of the WordPress.com. It can also be used as a plugin without any difficulty. But I see no harm in implementing this in the core patch of WordPress.com.
Anticipated Challenges : The time provided by GSoC team is sufficient to successfully complete the project. As of now I don’t see any anticipated challenges or risks as this is a very interesting and innovative idea with fool proof solution. Nevertheless, if any challenges come up during the course of the project, they will be worth accepting and defeating.
Potential mentors : No preference.

WordPress GSoC 2010 : Add AJAX Paging to Admin Screens

Project Description
My Idea : I have taken the idea from the list of suggested Ideas by WordPress, GSoC project mentors. I want to work on the project namely “Adding AJAX Paging to Admin Screens”.
There are millions of bloggers around the world who add posts dialy. There are areas where the internet connections are very slow. Pages takes minutes to load completely and this is sometimes very irritating. So Adding AJAX paging to all these kinds of list-type screens is a fantastic idea. Rather than loading the whole page again and again, we can just load the next set of posts (or whatever it is) keeping the rest of page untouched. This saves a lot of time and also reduces the burden on server. This is what I understood from the problem statement given.
The same script can be implemented to all screens like posts, pages, categories, users, comments sections etc… So this has a very wide scope and is very useful and interesting to work as a Summer Project. The user just mentions the number of posts per page and asks the next set. We can then make a XMLHttpRequest to get the next set of posts without bothering to refresh the whole page.
 Figure 1.1 |
 Figure 1.2 |
This is my tentative view of how the controls look. As shown in the above pictures, the user can enter how many posts he wants to see per page and also the page number he wants to directly navigate to. This is my how I will make it work.
Coding Approach : Depending on the value in posts per page control, I will first calculate the ‘ of ’ field in the second control(here 12 from figure 1.2). I will then use a mixture of HTML DOM and AJAX to do the rest. Whenever user changes value in posts per page or whenever the user clicks any of the arrows in second control(as in figure 1.2), I will make XMLHttpRequests to get the data accordingly. Using DOM I will then update that required section of the page. This feature can thus be implemented to any list-type screens and will be of great help to users of WordPress.com.
What have you done so far with this idea : I am studying the background PHP of list-type screens from offline version of WordPress.com. I then came up with this idea of ‘lists per page’ and ‘go to page’ which I think is a robust way of solving the above problem. I am working on AJAX hard so that I will be more comfortable with you whenever you ask me to do something. I am imitating the features of Gmail, like the autocomplete, pop-up window with user’s details whenever we hover over a particular user in chat box. So I think I have handsome experience and skill to work on this project.
I haven’t shared my idea with wp-hackers but would certainly love to. I will discuss with them if there can be a better solution to the problem. I will mail you immediately as and when I get some response from them. I will submit my work and progress frequently and try my best not to fail to meet any deadlines put up by you.
This will be certainly impleted in the core patch of the WordPress.com. I will double check everything and see to that nothing goes wrong. But if you want me to make it as a plugin, I will be happy to do that even. I see no harm in implementing this in the core patch of WordPress.com.
Anticipated Challenges : The time given by the GSoC team will be sufficient to succesfully complete the project.
