[TUTORIAL:] Creating a custom wallet. Part 1: Proof of concept.

Download and view this tutorial on GITHUB
I'm teaching myself the technical aspects of Bitcoin. I decided to start by making a custom wallet. Here is my quick and dirty proof of concept using Python, bitoinrpc, and PyQt.
So far, this only queries bitcoind for getinfo. It's only a stepping stone to the greater application.
I'll make more tutorials as the program develops. Please feel free to comment and ask questions. Keep in mind, Python isn't my primary language. I decided to go with Python only because I could use the practice.
I wrote this using Linux. It should work on Windows / Mac, but your mileage may vary. To use this, you are going to need Python 2.7 installed on your machine (obviously) as well as the dependent libraries: PyQt, Python bitcoinrpc, and json. Copy and paste the code in a file somewhere and run
$ python  
Change "rpc_username" and "rpc_password" to match that of ~/.bitcoin/bitcoin.conf
Make sure ./bitcoind -server is running
If everything is set up correctly you should see a gui app appear with the same information as if you were to run bitcoind getinfo from the command line.
#!/usbin/python # -*- coding: utf-8 -*- import sys from PyQt4 import QtGui from bitcoinrpc.authproxy import AuthServiceProxy import json class Configuration(): def __init__(self): self.protocol = "http" self.username = "rpc_username" self.password = "rpc_password" self.ip = "localhost" #self.port = "18332" self.port = "8332" def get_uri(self): self.uri = self.protocol+"://"+self.username+":"+self.password+"@"+self.ip+":"+self.port return self.uri class Command(): def __init__(self): self.conf = Configuration() self.access = AuthServiceProxy(self.conf.get_uri()) def get_info(self): self.info = self.access.getinfo() #self.info = self.access.listaccounts() return self.info class UI(QtGui.QWidget): def __init__(self): super(UI, self).__init__() self.init_ui() def init_ui(self): command = Command() info = command.get_info() keys = info.keys() label = [] line_edit = [] for (i, key) in enumerate(keys): label.append(QtGui.QLabel(str(keys[i]))) line_edit.append(QtGui.QLineEdit(str(info[keys[i]]))) grid = QtGui.QGridLayout() grid.setSpacing(10) for (i, item) in enumerate(label): grid.addWidget(label[i], i, 0) grid.addWidget(line_edit[i], i, 1) self.setLayout(grid) self.setGeometry(300, 300, 350, 300) self.setWindowTitle('getinfo') self.show() def main(): app = QtGui.QApplication(sys.argv) ex = UI() sys.exit(app.exec_()) if __name__ == '__main__': main() 
Features of note:
In the future I may just link to a github account. Time permitting.
Let me know what you think. Thanks!

Sending RPC commands to Bitcoin Client

I'm trying like hell to learn java, and with some success. However, I want to learn how to connect to my bitcoin rpc server and send commands, such as getinfo or sendfrom.
I understand that functions are called methods in java, so I'd like a method to actually initiate the connection and verify that it works by sending a getinfo command, then when it returns something that isn't null, have the ability to send other commands.
I know there are java classes and stuff that people have already written, but I want to write it for myself and understand better how it works and what is required.
I have experience with several different programming languages and part of my job is to write custom modules for our ERP system, which uses some stupid mashup of cobol and VB. So, any help would be greatly appreciated!!! Thanks!

Running Bitcoin with the -server argument (or running bitcoind) tells it to function as a HTTP JSON-RPC server, but Basic access authentication must be used when communicating with it, and, for security, by default, the server only accepts connections from other processes on the same machine. If your HTTP or JSON library requires you to specify which 'realm' is authenticated, use 'jsonrpc'. There are two variations of the original bitcoin program available; one with a graphical user interface (usually referred to as just Bitcoin), and a 'headless' version (called bitcoind ). They are completely compatible with each other, and take the same command-line arguments, read the same configuration file, and rea . trending; Bitcoin Rpc Commands Bitcoin . Bitcoin Rpc Commands .
