Hi, 
 
I'm using the following code to get a list of work flows. But I get 
 
invalid results. I get some work flows which are repeated many times. 
 
why is that ? This happens even when I deactivate the workflow. 
 
//Fetch XML 
 
ColumnSet columns = new ColumnSet(); 
 
columns.Attributes = new string[] { "name" ,"entitytype"}; 
 
QueryExpression query = new QueryExpression(); 
 
query.EntityName = EntityName.wfprocess.ToString(); 
 
query.ColumnSet  = columns; 
 
CrmService service = new CrmService(); 
 
service.Url = "http://<bla>:5555/mscrmservices/2006/crmservice.asmx"; 
 
service.Credentials =new 
 
NetworkCredential("user","pwd","domain"); 
 
BusinessEntityCollection users = 
 
service.RetrieveMultiple(query); 
 
int i=0; 
 
ddlWorkflows.Items.Clear(); 
 
foreach(wfprocess wfp in users.BusinessEntities) 
 
{ 
 
string name = wfp.name; 
 
string type = wfp.entitytype; 
 
ddlWorkflows.Items.Insert(i,name +"-"+ type); 
 
i++; 
 
} 
 
any ideas why i get one work flow multiple times? Is is possible to 
 
query inactive work flows? 
 
thanks in advance, 
 
Hassan.
