Validating activities sequence in a workflow

Posted By:      Posted Date: September 26, 2010    Points: 0   Category :Windows Application
Dear all,

I rehost a workflow designer and there is a flowchart activity as a default root activity in it. I want to validate the activities in the flowchart was arranged in the right order, e.g. Activity2 must be performed before Activity3, Activity1 must be performed after Activity3. How can I do it programmatically to the Xaml content generated by the designer?

Thanks in advance.

Custom sequence activity deriving from System.Workflow.Activities.SequenceActivity

Hi, I try to create custom sequence activity. I found some sample (http://social.msdn.microsoft.com/Forums/en-US/wfprerelease/thread/f54e8eb2-29d9-46f6-ad96-766fe6fad333/). But this custom activity looks ugly (to separate nested activity using ellipses instead of arrows). My question is - how to create custom sequence activity, which will look like sequence activity. I also found this sample - <ContentPresenter x:Uid="ContentPresenter_1" Content="{Binding}" Style="{x:Static sacdt:DesignerStylesDictionary.SequenceStyle}"/> When I used this ContentPresenter my custom activity looks like System.Workflow.Activities.SequenceActivity, but I couldn't put on it another activity. I also created class, which derives from System.Workflow.Activities.SequenceActivity, but I couldn't see it in toolbox. My question is - how to create class, which derives from System.Workflow.Activities.SequenceActivity and is visible in toolbox or how to use ContentPresenter for sequence activity, which allows put on itself another activity.

Problem validating StringBuilder fields in SharePoint 2010 Custom Workflow Validators


One of our custom SharePoint Designer workflow activities, which have always worked fine in SharePoint 2007, fails to validate.

This appears to happen when a Workflow Activity that contains a StringBuilder field also contains a lookup variable.

<FieldBind Field="CustomCode" Text="this code" Id="1" DesignerType="StringBuilder" />

For example when we store the following in this StringBuilder field

"Today's date = [%Current Item:Transaction Date%]"

This field returns 'null' in the ActivityValidator. As a result we cannot validate its contents.

Hidden Workflow Arguments to System.Activities.ActivityBuilder


Hi, I have rehosted the Workflow designer, and the base activity that i load is the Activity Builder(workflowDesigner.Load (activityBuilder);)

I basically need to add in some details to the activity, and the value of which the user should not be able to edit (or may be even see on the designer surface). For this I am (currently) adding some arguments as follows where i can add in the extra information.

activityBuilder.Properties.Add (new DynamicActivityProperty { Name = "HiddenArgument", Type = typeof (string), Value = "Value that the user should not edit." });

But as these arguments are visible on the designer surface in the Arguments Panel on the bottom of the designer, the user can edit this. i also have other arguments that the user is allowed to edit so therefore i cant disable the whole arguments pane.

I would just want to know how can i add my information to the workflow(and obviously save it in the *.XAML file) so that the user cant edit (or see) this information.

EXTRA DETAILS: I basically want something like, if i create a custom activity i can add properties with [Browsable(false)], which causes the user to not see the property on the right side pane but hold a value!

LINQ to SQL - Validating if item is in Database, but if item is not items not inserting into databas



I am new to this, so bear with me.  I am writing an application in C# that uses LINQ to validate a datacontext off a textbox to see if the record exists already.  If the record does exist I inserted an if statement to advise the user that the record exists, if the record does not exist I would like to allow the record to be added to the database.  If I take out my else statement everything works fine as far as inserting goes, but I do not want to allow inserts in this scenario.  I have tried moving the if and else statement to different parts of the code but can't quite figure this one out.  Any help would be apprecaited, attached is the code.  This code is set to a button press.  As a matter of fact, if you see any other errors along the way please feel free to point them out. 



    protected void enterBTN_Click(object sender, EventArgs e)
        //make new data context

        SHCDataContext insNewAll = new SHCDataContext();
        //LINQ to check if customer exists in database
        var checkExisting = from c in insNewAll.Customers
                            where c.custLastName.Contains(custLastNameTB.Text.ToString())
                            select c.custLastName;
        //make list to store values

Regex pattern for validating IPv6


Can anyone can make a regular expression pattern for validating IPv6 (not IPv4)?

Ipv6 has many formats and aliases. I tried making the pattern but written in a lot of codes (i'm not sure my code below will be 100% accepting valid formats and 100% declines invalid formats).

Foundations: Workflow Services for Local Communication


This month's column describes how to use WCF for communication between a workflow and a host application in Windows Workflow Foundation 3. This knowledge should help developers with their efforts using WF3 and prepare them for WF4, where WCF is the only abstraction over queues (referred to as "bookmarks" in WF4) that ships with the framework.

Foundations: Windows Workflow Design Patterns


Design patterns provide a common, repeatable approach to solving software development tasks, and many different patterns can describe how to accomplish a certain goal in code. When developers begin working with Windows Workflow Foundation (WF), they often ask about how to accomplish common tasks with the technology. This month's column discusses several design patterns used in WF.
