How to create an activity that allows multiple exit paths similar to FlowSwitch and FlowDecision

There have been several threads around this type of request but none have provided a definitive outcome for my requirements:I am looking to emulate the FlowSwitch or FlowDecision in a custom activity so as to simplify end user workflow authoring in a rehosted environment.Currenty I am limited to linking my custom activity to a FlowSwitch or FlowDecision to allow for simple logic to be visually composed. This creates additional complexity that I am trying to avoid.I understand that these are sealed types and even the abstract FlowNode base class of these types does not have any overridable types by design as WF 4.0 favours composition over inheritance.What options do I have to accomplish my objective?If activity composition is the response to my question then could I kindly request that some samples or links to samples are provided?

How can we create a custom activity like FlowSwitch?



When you drag a FlowSwitch activity, it will open the TypeAttribute Window to provide the type.

The activity expression is evaluated based on the type specified.

How can we incorporate the same behaviour in our custom activity? When drag the activity, it should pop-up the TypeAttribute window and accept the Type details.

How do you create a custom BDC data field that allows for multiple selected values?

I need help creating a custom data field using the BDC column as a base.  We need to allow for multiple selected values instead of just a single one.  I can't find anything on the net which shows how to do this.

Multiple Applications with Similar UIs


My company is getting ready to update several applications. Two of the applications share some common functionality. One of them is a WinForms project for in-house and the other is public facing for our customers. Both of the apps support event entry (an "event" is one of our business objects) in the exact same way.

The event entry process is very complex, with lots of validation, enabling and disabling, visibility toggling, etc. Initially, the apps were developed at different times without knowing that this shared functionality would occur which lead to a lot of code duplication and a synchronization nightmare.

Going forward, I would like to choose a model that fixes this problem. I would like to have a common class (or classes) that handle ALL of the logic in one place. For the most part, we've had the UI handle the "simple" validation (required fields, valid values, etc.) and how to display the form (visibility, enabling, etc.). We then had the "complex" validation handled by our business logic layer. Personally, I thought that the display handling should have been performed at the BLL since the changing of one property affected the display of others, but that seems like it would have required me to "hook" it into the UI (e.g., UI provides reference to its controls to BLL or BLL says whatever co

What are my options when I need to create a report with data from multiple sources?

Hello all,  What are my options when I want to create a report that will get records from multiple data sources based on data from a parameter? The user will enter the customer ID, I have to check that ID against 5 different data sources. Have you guys done anything similar? Should I leverage SSIS on this request, adding an extra layer of complexity? Should I do this all from SSRS? What are my options?

Cannot create email alerts for multiple users

create multiple columsn based on a passed in variable

Hi, I am clueless as to how the following would be done. Would appreciate imputs: i would be passed in a StartDate and EndDate along with a Period(Week,Month,Quarter,Year).  this would be an INT which is calculated in the following way -- Suppose he selects StartDate = 2010-01-01, EndDate = 2010-02-28, and Period = Weeks ---> Which would mean my resultset would have a additional 9 columns (9 weeks using DateDiff(Week,@startdate,@enddate) The number of fixed columns always will be 4 Total # of records that would always come back is > 10 something like this CategoryTypeId(int),ParentCategory(uniqueidentifier),Id(uniqueidentifier),Name nvarchar(50),Wk1,Wk2.....Wk9 1,xxxx,xxxx,'Shopping',650,300,1275....1000   (i dont't need to total the wk,month,qurter or yearly.This would be taken care on the front end) Thanks!

Create task activity break out inside a While loop

Hi I have developed a sharepoint state machine workflow. I want to assign a same task to more than one users, but unfortunatly, I cannot give the attribute "AssignTo" to more users in the code, even like this:"this.workflowTask1Properties.AssignedTo = "mydomain\\user01;mydoman\\user02", that will result in an empty value to the attribure.So, I involved the createtask activity in a While loop so I can asign deferent user in each loop, but It's very stange,  the loop always stopped in the second time, does anybody have met this issue?I have referensed Amit's question:http://social.msdn.microsoft.com/forums/en-US/windowsworkflowfoundation/thread/b238978d-f330-420c-823e-b77b0e19414d?prof=requiredbut I have no define the "correlation refernce " in my workflow.my code is here:public SPWorkflowTaskProperties workflowTask1Properties;public int abc;...private void OnWorkflowActivated(object sender, ExternalDataEventArgs e)        {            ...           this.abc = 0;           ...        }...private void CreateTask1(object sender, EventArgs e)        { 

DtsConfiguration - One configuration value to multiple paths?

I have an SSIS solution with two packages in it. One is a job that runs daily, and the other is a historical (which wipes the database and re-imports everything from scratch). Both packages need nearly identical values to run. Originally the data flow task in both packages had the same name - "Data Flow Task", and I could use the one set of configurations in the dtsConfig file. I've since renamed the Data Flow Tasks in both packages to - DFT Daily and DFT Historical respectively. So now I have a problem - do I duplicate all of the configuration entries, or is there a way to get a single configuration entry "deployed" into both packages' data flow tasks? So here is an example of what I had: <Configuration ConfiguredType="Property" Path="\Package\Data Flow Task.Variables[User::ProxyUsername].Properties[Value]" ValueType="String"> <ConfiguredValue>jplenderleith</ConfiguredValue> </Configuration> <Configuration ConfiguredType="Property" Path="\Package\Data Flow Task.Variables[User::RequiresProxy].Properties[Value]" ValueType="Boolean"> <ConfiguredValue>True</ConfiguredValue> </Configuration> Here is what I don't want to do: <Configuration ConfiguredType="Property" Path="\Package\DFT Historical Rates.Variables[User::ProxyUs

Do you know how to implement this? Thanks! 

Create Multiple datafields in a Web Service

I have been working on this for awhile.  What I am trying to do is to retrieve the telephonenumber, mail and physicalDeliveryOfficeName from active directory  I have debugged it and it seems to work but when I connect to the data source in Infopath, there is no value.  Also, the data source has a group field called "choice."  I have no idea what that is.  I am using a contact select to fill out and the value of the AccountId will populate another field.  I use this field to choose the LoginName on the query and then run the query on the data source.  This should pupulate the email, phone, and location fields on the main data source.  Here is a sample of my code: Imports System.Web.Services Imports System.Web.Services.Protocols Imports System.ComponentModel Imports System.Net Imports Microsoft.sharepoint Imports Microsoft.SharePoint.WebControls Imports System.DirectoryServices Imports System.Data ' To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line. ' <System.Web.Script.Services.ScriptService()> _ <System.Web.Services.WebService(Namespace:="http://microsoft.com/webservices/")> _ <System.Web.Services.WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _ <ToolboxItem(False)> _ Public Class GetADProperty     Inherits System

Flowchart workflow, custom "FlowDecision" activity?

Dear all, in order to simplify the workflow "design" we would like to build our own activities that return a result with one or more nodes. Something like the "True/False" nodes that come out of the FlowDecision Activity. I know that one could normally add a FlowDecision activity after our custom activity and insert the condition expression to redirect the flow based on the result... however this requires the ability to know the "content" of the previous activity, and for some users we're targeting it's not immediate. Thank you!Adriano
