Video: Windows Workflow Foundation: Logic and Looping

Presenter:Mike Taulty

Simple programming constructs such as looping and conditional logic are represented in Workflow. Here we take a look at how we can model conditions and loops.

Minute 0

Will consist on the assertion that swelling Susan Shaw says it is minutes or so into visual studio net framework is my talking on a working developer and platform group in Microsoft in the UK this is an assertion about the windows worth of foundation which is part of the win effect suite of technologies ex a lot of Windows XP service two and so 2003 is little that is about little foundation in particular while the unstable at how we can build conditional logic and how we can deliver painters of a simple programming constructs that we can do workflow as opposed to doing imperative code in assertion I m working on the February preview of Windows Mr with the February preview off the win affects working as viciously criticised in five visual studio understood

Minute 1

Is worth about it s a fun project with other sequential workflow application will host inside the console alcohol is conditional in so are very long designs here has built Virgo simple programs those little locks is put onto this life around a while loop has hanged an indefinite want to drive him on their little lived once her a conditional looking onto a figure that its properties here you can see there a vision the first condition will build will be a cold condition went on to select from the start that he had a choice of a cold condition or a rural condition of all the composers this year but the cold condition first suffered upper class mode and report an of everyone here can count

Minute 2

Initialised zero involve it in our coalition is all right method are continually being a has nh we have an unconditional event monks which call our British are losing out as there aren t not result as to whether we should carry on living on the sort has received countless and can then carry on living portfolio and she s also implement Council is a little bit naughty to the 11 registers are purposefully through it somewhere to assist ago and then put something into this this while activity about toolbox and so on a piece of code in order with the code is go ahead set the properties on a specified that I wouldn t go ahead and write something to the consul is watched by Howard

Minute 3

Will add one to this move I discount it down here so a similar piece of code from their our drop in his rudiment in a counter have forgotten little of his other than is configured the English into the wild configure condition or using a colour condition volleyed a different God than Serbia which metal provides the code condition and you can see in using are continually being that it while it is happily s end of the workflow to keep the engine Alliance Leicester s driver and another coach at the bottom after a while it will cut the properties of their will glad its code and would do a consort reline exilic if something life ak such as specified in visual studio and we got on well with the Hugo and printer townhouse

Minute 4

Even he are donor lies don t while if you look at properties again this was his condition will change it unconditionally losing his own accord and a less early a rural reference condition and although there are now in her 60s and names are going to carry on the moving building ever made that particular film and long forgotten as editor to go ahead for her condition means so we can click on edit the condition will also hear this condition is just a councillor s enough that a valid condition can see that this is an of my class we can have their we can build about code

Minute 5

To remove this particular piece of code that we ve got down here which says whether to continue living in is that turnout will underline on the special of condition are supposed to do indeed work off checking the condition ourselves get the same effect will feel the benefit of using his rural conditions are posted as writing a letter that we wrote a second ago to check whether to continue lumping in if something is not easier to change after you ve built and are running the workflow those perfectly possible to combatants were flowing in the future session in fact in is much more difficult over my even be impossible to come back to the workflow and change the method that we wrote the first time we did things such after a fairly thick survey if you like that method ago with a cold condition and should back to the choice

Minute 6

Rosalind can easily be replaced later on you can go with a code in a rural condition and it that way certainly charge looking it is easy to update a lead pipe having after a method which run as far and as a in the world that we can do something conditional somehow it felt you could invite only adjusting the wire loop because a while ago they contained one shape so that a limitation because we convinced that the physical are second in a sequence and then we can do anything we like within their multiple shapes within one sequence within one while the sofa and felt straight on to their will do of them perhaps to show sympathy with the existing visit to got dragged into this side of the adults winning logo of the condition on to the bachelor of the

Minute 7

Sewers were about the properties of the branch by the condition once again but his condition and that will condition will say it is them a terms smell a gone edit that and small leading counties less than five vascular so okay there I knows either dismantled envelope is so firm are began in strikers code onto here and would have had properties of that slow piece of code onto the particular activity and informal rights and the guy as well way out if of more than five research military grunt that can benefit of a run damage of unconditional logic is well

Minute 8

At easily can assure you time designing a poster of building into code a building and we have a choice of that code and condition only have a rule condition dealing a condition requires you to write method the rule condition does an animal condition is easy to change the later point in the summer tourist in the short session 1 only his basic programming constructs like a while and is now and then into his own specify conditions which can either take the form of a method I looks like an event handler and you have to specify whether to carry on mark referred to a rural rules are slightly little better than inside your code is this

Minute 9

A real code like syntax of the conditions of those rules and in an Adelaide avoid possibly it will got to the workflow and change those rules will look at those in future sessions with outset which is very simple would have a wildly British version will have news that was together both of the vehicle the condition activity group with a gun battle in a separate in a different session okay so I can go to want more information on the Windows workflow foundation will Christian developers centre up a Christian Microsoft com when effects are lead you to information on all the effects presentation communication and workflow orders and you dedicated site at www Windowsworkflow net is surely about the Windows workflow foundation is lots of examples and examples of their should feel free to mail me my e mail address is there on the screen and their provide feedback and so on

Minute 10

Under the Thatcher listening a lot to catch a
