Custom Activity

Follow the steps below to create Custom activity in Quickflow:

1. Modify the action xml or add the new action xml and then add the Quickflow related information as shown below

   <action name="Custom Action" supportforquickflow="true">

   <quickflow>

   <definitionProvider class="CustomAction.CustomActivityQuickflowDefinitionHandler" assembly="c:\CustomAction.dll" />

   <runtimeHandler class="QuickflowCustomActivity.CustomActivity" assembly="c:\netcoreapp2.2\QuickflowCustomActivity.dll" />

   </quickflow>

   <description>Execute Custom Act</description>

   <image resourcename="dummyaction.png" />

   <handler classname="CustomAction.CustomActionHandler" assembly="bin\CustomAction.dll" />

   <properties>

   <property category="cat_configuration" name="CustomProp" displayname="Custom Property" type="string" helpstring="Build Property" mandatory="false" supportforquickflow="true"></property>

   </properties>

   <return>

   <value helpstring="Set">Set</value>

   <value helpstring="Not Set">Not Set</value>

   </return>

   </action>

2. Create a class library targeting .Net Framework 4.8 which can read all the activity related information from the database. In the above example, CustomAction.CustomActivityQuickflowDefinitionHandler is a class which creates the parameters needed for the execution.

3. Decorate the class with the attribute DefinitionHandler(). Make sure the name passed as the argument to this attribute is same as the name mentioned in the action xml.

4. Refer the following assemblies. These can be found in the GAC & in the installation path (Bin)

   1. Skelta.Bpm.Actions.Core.dll

   2. Skelta.Bpm.Quickflow.Bridge.dll

5. Provide the class name and the assembly path under the definitionProvider node.

6. Create a class library targeting .Net 6 which executes the activity. In the above example, QuickflowCustomActivity.CustomActivity is a class which executes the activity.

7. Refer the following assemblies. These can be found under the <InstallPath>\Web\Quickflow folder.

   1. Skelta.Bpm.Actions.Core.dll

   2. Skelta.Bpm.Quickflow.Interfaces.dll

   3. Skelta.Bpm.QuickFlow.Logger.dll

8. Decorate the class with the attribute RuntimeHandler (). Make sure the name passed as the argument to this attribute is same as the name mentioned in the action xml.
