Error : Url does not contain MSCRMServices

I got this error while using Accessing Microsoft Dynamics CRM Web Services from onload of lead entity.

I used the sample given in SDK which calls the WhoAmI message with the Execute method to retrieve the ID of the current user.

Resolved the error by replacing the url

xmlhttp.open(‘POST’, SERVER_URL +’/mscrmservices/2007/crmservice.asmx’, false);

xmlhttp.open(“POST”, “http://myServerName:Port/MSCrmServices/2007/CrmService.asmx”, false);

SERVER_URL global variable actually returns

http://myServerName:Port/organizationname because of which we got the error.

Here is the final code that I used

//Define the soapBody for the WhoAmI request.

var soapBody = “<soap:Body><Execute xmlns=’http://schemas.microsoft.com/crm/2007/WebServices’><Request xsi:type=’WhoAmIRequest’ /></Execute></soap:Body>”;

//Wrap the Soap Body in a soap:Envelope.

var soapXml = “<soap:Envelope xmlns:soap=’http://schemas.xmlsoap.org/soap/envelope/’ xmlns:xsi=’http://www.w3.org/2001/XMLSchema-instance’ xmlns:xsd=’http://www.w3.org/2001/XMLSchema’>”;

soapXml += GenerateAuthenticationHeader();

soapXml += soapBody;

soapXml += “</soap:Envelope>”;

// Create the XMLHTTP object for the execute method.

var xmlhttp = new ActiveXObject(“Msxml2.XMLHTTP”);

xmlhttp.open(“POST”, “http://d-3638:5555/MSCrmServices/2007/CrmService.asmx”, false);

xmlhttp.setRequestHeader(“Content-Type”, “text/xml; charset=utf-8”);

xmlhttp.setRequestHeader(“SOAPAction”, “http://schemas.microsoft.com/crm/2007/WebServices/Execute”);

//Send the XMLHTTP object.

xmlhttp.send(soapXml);

// Create an XML object to parse the results.

xmlDoc=new ActiveXObject(“Microsoft.XMLDOM”);

xmlDoc.async=false;

xmlDoc.loadXML(xmlhttp.responseXML.xml);

// Get the user’s ID.

var userid = xmlDoc.getElementsByTagName(“UserId”)[0].childNodes[0].nodeValue;

New Events or Messages for Plug-ins in CRM 4.0

In CRM 3.0, following were the events against which we could have written our callouts

Pre/Post – Create, Update, Delete, Assign, SetState, Merge.

PreSend, PostDeliver.

In CRM 4.0, the above event are now referred as messages for plug-ins. All the above events that were in CRM 3.0 are there as well as there many new messages/events have been added against which plug-ins can be attached.

For e.g. we can attach a plug-in against AddMembers message for team entity which would fire when we are adding members to a team.or attach a plug-in against Retrieve message for say lead entity which would fire when retrieve method of CrmService is used.

We can find all the new messages and the entities on which they work in SDK.

Calling an ASP.NET web service asynchronously.

When we add a web reference to a web service behind the screen wsdl.exe is run which creates the proxy class. Proxy class contains both synchronous and asynchronous flavors of each web method.For simple HelloWorld() web method following methods are there in the proxy class

Public string HelloWorld()

Public string HelloWorldAsync();

Public string HelloWorldAsync(object userState);

We call the HelloWorldAsync() method which in turn calls the following method of the proxy class InvokeAsync()

// Summary:

// Invokes the specified method asynchronously.

// Parameters:

// methodName:

// The name of the method to invoke.

// parameters:

// The parameters to pass to the method.

// callback:

// The delegate called when the method invocation has completed.

protected void InvokeAsync(string methodName, object[] parameters, SendOrPostCallback callback);

HelloWorldCompletedEventArgs– This class is also created by wsdl.exe which contains the result of our operation.

Suppose this is our simple web service, we have introduced delay to understand the asynchronous behavior.

[WebMethod]

public string HelloWorld() {

Thread.Sleep(5000);

return “Hello World”;

}

Now to call the above webservice method asynchrously in a windows application client we need to do the following

Say we have want to call the HelloWorld method asynchronously on the click of the button,

private void btnCallService_Click(object sender, EventArgs e)

{

// Create the instance of the proxy class

Service myService = new Service();

// Register an eventhandler for HelloWorldCompleted event

// The eventhandler would be called when the request is

// completed

myService.HelloWorldCompleted += new

HelloWorldCompletedEventHandler(this.HelloWorldCompleted);

// instead of calling the synchronous HelloWorld() we need

// to call the HelloWorldAsync() method

myService.HelloWorldAsync();

}

void HelloWorldCompleted(object sender,HelloWorldCompletedEventArgs args){

// Display the reutrn value

MessageBox.Show(args.Result);

}

To call the above web method in an asp.net client we need to add the following attribute in the @Page directive

Async=”true”

Executing CRM Workflow programmatically from an external application. CRM 4.0 using ExecuteWorkflowRequest

There is a method named ExecuteWorkflowRequest using which we can execute our workflow programmatically. We had a requirement to find all the opportunities which haven’t been modified for past 30 days and to decrease their probability attribute value by 10.

Now the thing over here was that there wasn’t any specific event against which we could have fired the above workflow. So we thought of writing an application which than we could scheduled, which will periodically run the above workflow

This is how we implemeneted it within a windows application

private void Form1_Load(object sender, EventArgs e){

CrmAuthenticationToken token = new CrmAuthenticationToken();

token.OrganizationName = “organizationName”;

//0 – AD

//1 – Passport

//2 – Form Authentication

token.AuthenticationType = 0;

CrmService crmService = new CrmService();

crmService.Credentials = System.Net.CredentialCache.DefaultCredentials;

crmService.CrmAuthenticationTokenValue = token;

crmService.Url = “http://servername:port/mscrmservices/2007/crmservice.asmx”;

try{

// Create an ExecuteWorkflow request.

ExecuteWorkflowRequest request = new ExecuteWorkflowRequest();

//Assign the ID of the workflow you want to execute to the request.

// use this query to get the id select parentworkflowid,name,* from dbo.Workflow

// id is the parentworkflowid

request.WorkflowId = new Guid(“21B9528D-D13D-4B93-9F91-FA7468D3C82C”);

// We want to run it against all the opportunity which are in open state

ArrayList OpportunityGuids = GetOpportunityGuids(crmService);

foreach (String oppGuid in OpportunityGuids){

//Assign the ID of the entity to execute the workflow on to the request.

request.EntityId = new Guid(oppGuid);

ExecuteWorkflowResponse response = (ExecuteWorkflowResponse)crmService.Execute(request);}

// Execute the workflow. }

catch (SoapException ex){

// write in log}

catch (Exception ex){

// write in log} }

private ArrayList GetOpportunityGuids(CrmService crmService){

// using QueryByAttribute to retrieve all the opportunity having statuscode as 1 i.e. Open

QueryByAttribute myOppQuery = new QueryByAttribute();

myOppQuery.Attributes = new String[] { “statuscode” };

myOppQuery.Values = new String[] {“1”};

ColumnSet myCols = new ColumnSet();

myOppQuery.ColumnSet = myCols;

myOppQuery.EntityName = EntityName.opportunity.ToString();

WindowsFormsApplication2.CrmSdk.BusinessEntityCollection myOppCollection= crmService.RetrieveMultiple(myOppQuery);

ArrayList opportunityGuids = new ArrayList();

foreach (WindowsFormsApplication2.CrmSdk.BusinessEntity opp in myOppCollection.BusinessEntities ){

opportunity myOpp = (opportunity)opp;

opportunityGuids.Add(myOpp.opportunityid.Value.ToString()); }

return opportunityGuids;

}

Error: The request failed with HTTP status 401 or Error 401.2: Unauthorized while using CrmService in ASP.NET or windows application CRM 4.0

To use CrmService or Metadata Service (CRM 4.0) within an ASP.NET page or a windows application we need to make use of CRM Authentication token.If we are using Active Directory Authentication this is the code for that

CrmAuthenticationToken token = new CrmAuthenticationToken();

token.OrganizationName = “organizationName”;

//0 – AD

//1 – Passport

//2 – Form Authentication

token.AuthenticationType = 0;

CrmService service = new CrmService();

service.Credentials =System.Net.CredentialCache.DefaultCredentials;

service.CrmAuthenticationTokenValue = token;

service.Url = “http://servername:port/mscrmservices/2007/crmservice.asmx”;

try{

WhoAmIRequest myReq = new CrmSdk.WhoAmIRequest();

WhoAmIResponse myResp = (CrmSdk.WhoAmIResponse)service.Execute(myReq);

}

catch (SoapException ex){

Response.Write(ex.Detail.InnerText);

}

catch (Exception ex){

Response.Write(ex.Message);}

If we get the above unauthorized access error it could be because either there is problem in our CrmAuthenticationToken, may be we could have assigned wrong organization name or authentication type. If we are using CrmService in an ASP.NET page than we need to use impersonation.
