CUserAuth Caller,
WORKFLOW_PROCESS_TYPE ProcessType,
ObjectType EntityType,
string ColumnSetXML
);
[C++]
public: String* RetrieveByCategory(
CUserAuth* Caller,
WORKFLOW_PROCESS_TYPE ProcessType,
ObjectType EntityType,
String* ColumnSetXML
);
Parameters
Caller
Specifies the identity of the caller. The caller must have the prvReadWorkflowProcess privilege to perform this action. See CUserAuth.
ProcessType
Specifies the process type. See WORKFLOW_PROCESS_TYPE.
EntityType
Specifies the type of the object. See ObjectType. Set EntityType to otNone to retrieve all processes.
ColumnSetXML
Specifies an XML string describing the set of columns that is to be retrieved. Passing "" or null returns all columns. You can find the valid column names in wfprocess.xsd. See also ColumnSetXML Schema.
Return Value

Remarks
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.Proxy.BizUser bizUser = new Microsoft.CRM.Proxy.BizUser ();
bizUser.Credentials = System.Net.CredentialCache.DefaultCredentials;
bizUser.Url = strDir + "BizUser.srf";
// CRMProcess proxy object
Microsoft.CRM.Proxy.CRMProcess process = new Microsoft.CRM.Proxy.CRMProcess();
process.Credentials = System.Net.CredentialCache.DefaultCredentials;
process.Url = strDir + "CRMProcess.srf";
string strErrorMsg;
try
{
Microsoft.CRM.Proxy.CUserAuth userAuth = bizUser.WhoAmI();
// Set up the columns that you want to retrieve
string strColumnSetXml = "<columnset>";
strColumnSetXml += "<column>name</column>";
strColumnSetXml += "<column>description</column>";
strColumnSetXml += "<column>eventtypecode</column>";
strColumnSetXml += "<column>processtypecode</column>";
strColumnSetXml += "</columnset>";
string strResultsXml = process.RetrieveByCategory(userAuth, Microsoft.CRM.Proxy.WORKFLOW_PROCESS_TYPE.WFPT_WORKFLOW_PROCESS, Microsoft.CRM.Proxy.ObjectType.otActivity, 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 );
