AVEVA Work Tasks provides a set of interfaces and their supporting classes and members that can be implemented in the class of a custom activity to develop a AVEVA Work Tasks human activity.

The following code sample shows how to create a sample Approval activity that looks and behaves like the AVEVA Work Tasks defined Approval activity.

To create a Sample Custom Approval Activity

Go to Start > Visual Studio 2005 > New > Projects->Class Library->SampleApprovalActivity. This step will create a Class Library project in the path specified by the name SampleApprovalActivity.
Create two class files under the project SampleApprovalHandler.cs and SampleApprovalControl.cs.
In the SampleApprovalHandler.cs class file, inherit the HWSActivityProviderBase class which is the base class for all the resource activities.
In the SampleApprovalControl.cs class file, inherit the class ActivityUIBase which while rendering the Work Item detail view. Inherit the INativeWebFormUIControl interface and it is used for setting the Current Work Item context to be used in Work Item detail view.

Build the Class Library Project and place the assembly in the SkeltaInstalledPath\BPM.Net\bin folder.
Create an HTML Page by the name SampleApproveUI.htm in the SkeltaInstalledPath\BPM.NET\WorkflowElements\Default\en-US\Activities\Activity\ folder which is getting used for rendering the UI. Please copy the contents below in the created HTML page.

Configure the Actions.Xml which will be in Skeltainstalledpath\BPM.NET\WorkflowElements\Default\en-US\Actions\XML for the Created Sample Approval under the Custom Activities Category. While configuring the Custom Activity, we need to specify the image filename of PNG type of size 40x40 for the custom activity which should be in the following folders. [SkeltaInstalledPath]\BPM.NET\WorkflowElements\Default\en-US\Actions\Images\Normal\Large, [SkeltaInstalledPath]\BPM.NET\WorkflowElements\Default\en-US\Actions\Images\Selected\Large,[SkeltaInstalledPath]\BPM.NET\BPMUITemplates\Default\ActivityImages.

Note: If an XML exception occurs after copying the below configuration in Actions.XML, open the actions.xml file in the browser and remove the extra spaces if any.
