Flowchart workflow is a new type of Hybrid workflow in WF 4.0. In this work flow we can able to use all type of WF 4.0 activities.
In this Flowchart workflow i am using FlowDecision activity to make Decision .
Flow Decision activity contains a Boolean expression Condition. If the expression evaluates to “True”, the true path is executed otherwise, the false path is scheduled
This expressions are written in VB!. This means capitalization does not matter, comparison is performed using a single equals sign instead of “==”, and the Boolean operators are the words "and" and "or" instead of the symbols "&&" and "||". [I think in feature we will able to edit in C#]
Next i am using my Custom activity for to read user input from console . [ please refer my pervious blog post how to create custom activity http://mstecharchitect.blogspot.com/2009/05/creating-custom-activity-for-reading.html]
In this Flowchart workflow i am giving an example of Bank Account creation. First i will greet the customer then ask customer to choose what type of account they wanted to create. Once customer input is read then using Flow Decision activity i am checking C for Checking and S for Saving account.
accType.ToUpper() = "C" [ expression to validate or check user input ]
if Input is C then create checking account and assign customer checking account number print them and say thanks and start the workflow from start.
if Input is S then ask details for to create a saving account. Here i am asking a questions to customer saying that what is your favorite Search engine ? B-Bing & G-Google. if customer input was B then create a Saving account and assign account number print them and say thanks. if customer input is G then i print a message saying that "Wait for Google to Open a Bank"
In this project i have defined the following list of variables as shown below.
Here is the Flowchart workflow in WF 4.0 designer.
