[RELEASE][WINDOWS] AddressWatch - A tool to monitor your bitcoin addresses

[physalis]

Recently, I found that I spent way too much time just copying addresses, pasting them to blockchain.info, then checking all the time while I wait for confirmations.
That was my inspiration to create AddressWatch. I've been using it for a while now and find it to be quite useful.

Features
- Monitors your clipboard for Bitcoin addresses.
- Whenever you copy a bitcoin address, it creates a window on the side of the screen that monitors the address.
- Shows  balance, recent transactions and their confirmation-levels
- Can show a QR code for the address
- Allows to maintain a "WatchList" of addresses that you can assign a name and that are saved for the future and monitored in the background
- Gives notifications if the balance of an address on the WatchList changes

The program doesn't interact directly with the blockchain.
It queries blockchain.info, so it depends on the availability of this site.

The source (.NET C#) is included in the .zip, I'd really like it if someone could verify that it doesn't contain any malicious code.

Download & Run:
v.1.1 - QRCode functionality added (right click the address to show), also minor improvements

Make sure you have .NET framework 4.5 installed.
Unzip and start "BTCAddressWatch.exe" in the "bin" folder.
The program is then running in the background, so you will not notice anything happen right away.
Try ctrl+c'ing a bitcoin address and a window should pop up.
You can access the settings and other stuff via the icon in the taskbar.

Older Versions:
v.1.0

Planned future features:
- Allow creating and showing a QR code for the address
- Allow invoke by hotkey, not by monitoring the clipboard
- Allow display in mBTC
- ...

Please let me know what you think. I'm open for any ideas or suggestions.
Please also report any bugs you might find.

Nice, I had plans (still kind of plan to, just need to find the time) to do something similar using javascript and html, so I could just have it run on a tab in my browser.

I'm assuming this uses the .NET framework.  Which version did you build it with?

Cool features

Looks pretty good and does the job well!

As it appears this requires .NET 4.5, you might want to lower the requirements down to 2.0 if possible to attract a larger audience.

Yes, it's 4.5. Thanks for the hint, I'll check out tomorrow if I can lower the target framework without any problems.
I'm planning to add the QR Code functionality tomorrow and if all goes well, I'll put the next version up with that and a lower target.

nothing blatantly viral.

This code relies on blockchain.info being accessible. 

Code:

        public JArray GetTransactions(Address address)
        {
            string contents = "";
            string latestBlock = "";
            using (var client = new WebClient())
            {
                //queries blockchain.info API
                try
                {
                    contents = client.DownloadString("http://blockchain.info/rawaddr/" + address.address);
                    latestBlock = client.DownloadString("http://blockchain.info/latestblock");
                }

[physalis]

Thanks for reviewing the code!

 I mentioned that in the OP though.

The program queries blockchain.info, so it depends on the availability of this site.

Indeed, I see that now. 

I was excited you did something local like scanning the blockchain files on the hard drive or connect to the qt client interface. 

I am struggling with that right now, but I don't want to get off topic.

Sorry to disappoint you 
I was thinking about trying to interface with the local blockchain, to have it as a second option. But after looking into it (albeit just superficially) I got to the same problem that you're describing: it's just not that easy to find transactions that involve a specific address. You'd basically wade your way through all blocks in the chain and cherry-pick out every transaction.
I gave up on the thought since I didn't want my program to rely on the user running a full node. And as a second option for the people that do, it didn't seem worth the trouble.
But if you happen to find a way to do this without heavy calculations/resource usage, please let me know.

QRCode functionality added



Unfortunately, the JSON library I used requires .NET framework 4.5, so I can't lower it for now :/

hi just tried your tool.

I ran it and tried to add my first address by ctrl+c by it crashed out with this error

edit: Running win7 x64 .net 4.5 installed

edit2: seems to crash out if there is a BTC address on the clipboard before the program is ran

Code:

Program crashed on transactions with newly generated coins (null pointer on the inputs )

Fixed.

Using closed source software like this is asking for your coins to get stolen.

Don't know where you got that. It's completely open source, the source is included in the download (as I already mention in the OP).
I encourage everyone to review the code and compile it themselves if they are concerned.

I'm not a thief, just giving something back to the community

Nice, i built a similar tool, but it is an online bitcoin address monitor
