CRMArticle.RetrieveByState Method

The RetrieveByState method retrieves all the articles with the specified state for the specified organization.

Syntax

[Visual Basic .NET]
Public Function RetrieveByState(
  ByVal Caller As CUserAuth,
  ByVal OrganizationId As String,
  ByVal State As UInt32,
  ByVal ColumnSetXML As String
) As String

[C#]
public string RetrieveByState(
  CUserAuth  Caller,
  string  OrganizationId,
  uint  State,
  string  ColumnSetXML
);

[C++]
public: String* RetrieveByState(
  CUserAuth*  Caller,
  String*  OrganizationId,
  unsigned long  State,
  String*  ColumnSetXML
);

Parameters

Caller

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

OrganizationId

Specifies the ID of the organization.

State

Specifies the state of article to be retrieved. See KBARTICLE_STATEColumnSetXMLSchema.

ColumnSetXML

Specifies an XML string describing the set of columns that is 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 kbarticle.xsd. See also ColumnSetXML Schema.

Return Value

Returns a String type that specifies the XML data representing the articles retrieved. The fields that are returned depend on what fields are specified in the ColumnSetXML parameter. This XML string is in the format

<kbarticles> + kbarticle1..N + </kbarticles>

where the XML schema for each article is described by kbarticle.xsd.

Remarks

Unlike the Retrieve method, 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";

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

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

   // Valid Organization ID
   string strOrgId = "{3BECB6A6-0DD8-4061-98D9-0B9E897C5027}";
   uint state = Microsoft.Crm.Platform.Types.KBARTICLE_STATE.KBAS_PUBLISHED;

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

   // Retrieve the articles
   string strArticlesXml = article.RetrieveByState (userAuth, strOrgId, state, 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 );
}
