CRMProcessController.RetrieveProcessesByObject Method

The RetrieveProcessesByObject method retrieves all of the workflow processes that can be run by an object.

Syntax

[Visual Basic .NET]
Public Function RetrieveProcessesByObject(
  ByVal Caller As CUserAuth,
  ByVal ProcessType As WORKFLOW_PROCESS_TYPE,
  ByVal Object As CObjectName,
  ByVal ColumnSetXML As String
) As String
[C#]
public string RetrieveProcessesByObject(
  CUserAuth  Caller,
  WORKFLOW_PROCESS_TYPE  ProcessType,
  CObjectName  Object,
  string  ColumnSetXML
);
[C++]
public: String* RetrieveProcessesByObject(
  CUserAuth*  Caller,
  WORKFLOW_PROCESS_TYPE  ProcessType,
  CObjectName*  Object,
  String*  ColumnSetXML
);

Parameters

Caller

Specifies the identity of the caller. To perform this action, the caller must have the prvReadWorkflowProcessInstance privilege and access rights on the objects to be retrieved. See CUserAuth.

WORKFLOW_PROCESS_TYPE

Specifies the process type. See WORKFLOW_PROCESS_TYPE.

Object

Specifies the object to find. See CObjectName.

ColumnSetXML

Specifies an XML string describing the set of columns to be retrieved. Passing an empty string or null returns all columns (Nothing or "" in VB .NET). You can find the valid column names in wfprocess.xsd. See also ColumnSetXML Schema.

Return Value

Returns a String type that specifies the XML data containing the set of processes. The fields that are returned depend on what fields are specified in the ColumnSetXML parameter. This XML string is in the format

<wfprocesses> + wfprocess1..N + </wfprocesses>

where the XML schema for each process is described by wfprocess.xsd.

Remarks

The XML string returned from this method may contain multiple objects. If no objects are returned the method simply returns an XML document for the object type with no data.

The XML string returned from this method does not contain elements for fields where the value is null or contains empty strings. This improves performance by not sending more XML data than is necessary from the server to the client.

If there is an error, SOAP throws an exception and the error message is reported in System.Web.Services.Protocols.SoapException.Detail.OuterXml.

All IDs passed to the platform are GUIDs wrapped in braces. For example: {6522D89A-A752-4455-A2B0-51494C6957C3}

Example

[C#]
// strServer should be set with the name of the platform Web server
string strServer = "myservername";

// virtualDirectory should be set with the name of the Microsoft CRM
// virtual directory on the platform Web server
string virtualDirectory = "mscrmservices";
string strDir = "https://" + strServer + "/" + virtualDirectory + "/";

// BizUser proxy object
Microsoft.Crm.Platform.Proxy.BizUser bizUser = new Microsoft.Crm.Platform.Proxy.BizUser ();
bizUser.Credentials = System.Net.CredentialCache.DefaultCredentials;
bizUser.Url = strDir + "BizUser.srf";

// CRMProcessController proxy object
Microsoft.Crm.Platform.Proxy.CRMProcessController   processcontroller  = new Microsoft.Crm.Platform.Proxy.CRMProcessController();
processcontroller.Credentials = System.Net.CredentialCache.DefaultCredentials;
processcontroller.Url = strDir + "CRMProcessController.srf";

string strErrorMsg;
try
{
   Microsoft.Crm.Platform.Proxy.CUserAuth userAuth = bizUser.WhoAmI();

   string strLeadId = "{4AAD6AD1-244C-4270-86A2-046BF3CAC92F}";

   Microsoft.Crm.Platform.Proxy.CObjectName objName = new Microsoft.Crm.Platform.Proxy.CObjectName();
   objName.Id = strLeadId;
   objName.Type = Microsoft.Crm.Platform.Proxy.ObjectType.otLead;

   // Set up the columns that you want to retrieve
   string strColumnSetXml = "<columnset>";
   strColumnSetXml += "<column>priority</column>";
   strColumnSetXml += "<column>description</column>";
   strColumnSetXml += "<column>processid</column>";
   strColumnSetXml += "</columnset>";

   // Retrieve by object
   string strProcessXml = processcontroller.RetrieveProcessesByObject (userAuth, Microsoft.Crm.Platform.Proxy.WORKFLOW_PROCESS_TYPE.WFPT_WORKFLOW_PROCESS, objName, strColumnSetXml);
}
catch (System.Web.Services.Protocols.SoapException err)
{
   // Process the platform error here
   strErrorMsg = ("ErrorMessage: " + err.Message + " " + err.Detail.OuterXml + " Source: " + err.Source );
}
catch (Exception err)
{
   // Process other errors here
   strErrorMsg = ("ErrorMessage: " + err.Message );
}
