CRMProcess.RetrieveRule Method
The RetrieveRule method retrieves the specified rule for a process step.
Syntax
[Visual Basic .NET]
Public Function RetrieveRule(
ByVal Caller As CUserAuth,
ByVal RuleId As String,
ByVal ColumnSetXML As String
) As String
[C#]
public string RetrieveRule(
CUserAuth Caller,
string RuleId,
string ColumnSetXML
);
[C++]
public: String* RetrieveRule(
CUserAuth* Caller,
String* RuleId,
String* ColumnSetXML
);
Parameters
Caller
Specifies the identity of the caller. To perform this action, the caller must have the prvReadWorkflowProcess privilege and access rights on the object to be retrieved. See CUserAuth.
RuleId
Specifies the ID of the rule to be retrieved.
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 wfrule.xsd. See also ColumnSetXML Schema.
Return Value
Returns a String type that specifies the XML data containing the rule. The fields that are returned depend on what fields are specified in the ColumnSetXML parameter. The XML schema is described by wfrule.xsd.
Remarks
This method always returns a single object so any filter criteria specified in the ColumnSetXML parameter are ignored.
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";
// CRMProcess proxy object
Microsoft.Crm.Platform.Proxy.CRMProcess process = new Microsoft.Crm.Platform.Proxy.CRMProcess();
process.Credentials = System.Net.CredentialCache.DefaultCredentials;
process.Url = strDir + "CRMProcess.srf";
string strErrorMsg;
try
{
Microsoft.Crm.Platform.Proxy.CUserAuth userAuth = bizUser.WhoAmI();
string strRuleId = "{FC0C4939-7AD1-4BA8-B418-6D4D55459833}";
// Set up the columns that you want to retrieve
string strColumnSetXml = "<columnset>";
strColumnSetXml += "<column>stepid</column>";
strColumnSetXml += "<column>description</column>";
strColumnSetXml += "<column>name</column>";
strColumnSetXml += "</columnset>";
// Retrieve the rule
string strRuleXml = process.RetrieveRule(userAuth, strRuleId, 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 );
