Excel AddIn

Qpid .net comes with Excel AddIns that are located in:

<project-root>\qpid\dotnet\client-010\addins

There are currently three projects:
ExcelAddIn: An RTD excel Addin
ExcelAddInProducer: A sample client to demonstrate the RTD AddIn
ExcelAddInMessageProcessor: A ample message processor for the RTD AddIn

Qpid RDT AddIn

Deploying the RTD AddIn

Excel provides a function called RTD (real-time data) that lets you specify a COM server via its ProgId here "Qpid" so that you can push qpid messages into Excel.

The provided RTD AddIn consumes messages from one queue and process them through a provided message processor.

For using the Qpid RTD follows those steps:

1) Copy the configuration Excel.exe.config into Drive\Program Files\Microsoft Office\Office12

2) Edit Excel.exe.xml and set the targeted Qpid broker host, port number, username and password.

3) Select the cell or cell range to contain the RTD information

4) Enter the following formula =rtd("Qpid",,"myQueue") Where MyQueue is the queue from which you wish to receive messages from

Note: The Qpid RTD is a COM-AddIn that must be registered with Excel. This is done automatically when compiling the Addin with visual studio.

Defining a message processor

The default behavior of the RDT AddIn is to display the message payload. This could be altered by specifying your own message processor.
A Message processor is a class that implements the API ExcelAddIn.MessageProcessor. For example, the provided processor in client-010\addins\ExcelAddInMessageProcessor displays the message body and the the header price when specified.

To use you own message processor follows those steps:
1) Write your own message processor that extends ExcelAddIn.MessageProcessor
2) Edit Excel.exe.config and uncomment the entries:
<add key="ProcessorAssembly" value="<path>\qpid\dotnet\client-010\addins\ExcelAddInMessageProcessor\bin\Debug\ExcelAddInMessageProcessor.dll"/>
<add key="ProcessorClass" value="ExcelAddInMessageProcessor.Processor"/>

• ProcessorAssembly is the path on the Assembly that contains your processor class
• ProcessorClass is your processor class name
  3) run excel and define a rtd function

Note: the provided ExcelAddInProducer can be used for testing the provided message processor. As messages are sent to queue1 the following rtd function should be used =rtd("Qpiud",,"queue1")
