What it does:
Replace all files in a folder with identical filename AND SHA1 hash as original.file with new.file.

Use Cases
Say I have updated the contents of a php file that is used multiple times throughout my project, and now I want all other copies of that file to be updated as well.
In most cases the following code would work:
However if the file is readme.txt or config.php for example, then you'd have overwritten many wrong copies. Using HashReplace only files with the same name and same contents will be overwritten with the new contents.

I promised to make an App as a thank you to DC members, so here it is.

Description (of the application) :

Displays a photo on the desktop wallpaper in overlap manner, so that one can have the photo of loved ones on different wallpaper images on desktop. The overlapped photo can be sized, and positioned on desktop as required; and also can be made semi transparent.


Benefits (of using it) :

I like to have my family photo on my desktop (who don't). Now sometime I come across a good nature image as desktop wallpaper (I like nature, abstract etc.). To have my loved ones photo over the nature's wallpaper, I open up image editor, adjust the two images, save and set as wallpaper, done. In another few months, I find a breath taking image of water fall and want it as my wallpaper. Open image editor, and ... done. When I need to change the family photo with the latest naughty one of my son, I look for the image editor, and ... done.

Well as a developer, somewhere inside me I was not feeling good. I wanted the benefit of both worlds and in automated manner.

Googling gave me many freeware wallpaper changers and some with collage facility. All these does the job but not as I required. I wanted the wallpaper to change the main background image but keep my family photo overlapped on it.

I made one, which does as required. It shows the given image overlapped on the existing desktop wallpaper. Further one can use a wallpaper changer and have the loved ones photo always overlapped on different wallpaper images.

My colleagues, who wanted the same but could not use image editor properly, love it. We all have our religious photo (looks like we all turn religious as the pay day nears), overlapped on different wallpapers on all our desktop now.

Hope you will find this software useful.

Excel2Html

Description
A command-line tool to convert Excel data into html like the Mail Merge feature of Word. Created as a resolution to this until now unfinished Coding Snack, during the March 2011 fundraiser event.

Features
Convert Excel data into 1 big html table (singlefile mode) or each row into a single html file, or multifile mode where the names of the file can either be based on row number of column data (multiple columns can be used), and each column can be output anywhere the html based template allows.

To celebrate the fundraiser, DC member skwire has released a new application: sWeather.

But before I describe sWeather, I need to say a little bit more about Skwire.  Over the last year he has released an absolutely astounding number of brand new freeware programs over the last year - almost all in response to requests from everyday people who have stopped by and posted on the DonationCoder.com Coding Snacks Request board.  He's almost threatening to break the record for releases by DC member Skrommel.  It's great fun to watch Skwire create new tools based on user requests.

Ok back to the new app, sWeather.  It's a tray-based weather tool.  There are a few of these kinds of tools around, some good, some bad.  sWeather is nice because it looks great while being pretty minimalist, and does all of the important things well.  There are tray icons for weather condition and temperature, and it's easy to switch quickly between locations and perform update checks. Overall a very sweet tool.

Important Note: During the fundraiser we ask people to make new donations into the site.  And these donations help cover site hosting costs and other expenses.  But we also have a system we created (called DonationCredits) in order to let people direct their donations to specific members on the site who they would like to show support to.  The best thing you could do with your donation is actually to send your donation credits out to specific people on the site like Skwire, whose work you want to support - as a way of letting them know that their work is appreciated.  So don't just donate, spread the love a little by sending your donation out to people on the site like skwire.  Actually skwire has his own direct paypal donation button on his website, and that would also be a great way to let him know he is appreciated.
