Creating and Sending email in CRM using SendEmaiRequest

We can use the following code for creating and sending an email in CRM

/// <summary>
/// Creating and Sending mail in CRM
/// </summary>
/// <param name=”crmService”>an instance of crmService (CrmService for CRM 3.0)</param>
/// <param name=”members”>ArrayList containing guids of the members</param>
/// <param name=”msg”>The message body</param>
/// <param name=”ownerID”>Owner of the record</param>
/// <param name=”userID”>User under whose context the callout or plugin is running </param>
private void SendMailToMembers(ICrmService crmService, ArrayList members, String msg, String ownerID, String userID)
{

// create an email
email emailCreate = new email();
emailCreate.subject = “MySubject”;
emailCreate.description = msg;

//specify the owner for the mail
emailCreate.ownerid = new Owner();
emailCreate.ownerid.type = EntityName.systemuser.ToString();
emailCreate.ownerid.Value = new Guid(ownerID);

//create an activityparty array holding all the guids specified in the members array list
activityparty[] ap = new activityparty[members.Count];
// creating as many activity party as the no of users or members in a team
int i = 0;
foreach (String memberID in members)
{
ap[i] = new activityparty();
ap[i].partyid = new Lookup();
ap[i].partyid.type = EntityName.systemuser.ToString();
ap[i].partyid.Value = new Guid(memberID);
i++;
}

// specify to part of the email
emailCreate.to = ap;

// specify the from part of the email
activityparty from = new activityparty();
from.partyid = new Lookup();
from.partyid.type = EntityName.systemuser.ToString();
from.partyid.Value = new Guid(userID);
emailCreate.from = new activityparty[] { from };

// finally create the email and get the guid of the email
Guid emailId = crmService.Create(emailCreate);

// FOR CRM 3.0
// Specify the system user who is sending the message.
//crmService.CallerIdValue = new CallerId();
//crmService.CallerIdValue.CallerGuid = new Guid(userID);
//

// Create an SendEmailRequest object
SendEmailRequest req = new SendEmailRequest();
req.EmailId = emailId;
req.TrackingToken = “”;
req.IssueSend = true;

// Finally Send the email message.
SendEmailResponse res = (SendEmailResponse)crmService.Execute(req);
}

PreEntity and PostEntity Images in CRM 4.0

Hi ,

When writing callouts for CRM 3.0, we were provided with PreEntityImageXml and PostEntityImageXml as a parameter to methds being overrided by us.

We could specify the fields for the same in the callout.config as prevalue and postvalue tag.

But the things have changed a bit in CRM 4.0.

Here we have to implement the Execute method found in the interface IPlugin.

public void Execute(IPluginExecutionContext context)

Here first we will register our assembly using Plugin Registration Tool

Than we will register a new step and specify the message against which we want to run our plugin.

After this comes the step where we will Register new image.

In Register New Image dialog box

We can specify Pre Image and Post Image depending upon pre or post event. (Only for post event we can have both pre and post image)

Parameters -Here we can either specify certain fields or can select all attributes.

Entity Alias – Give a name to our image which we will refer in our code. (eg. say we gave LeadImage)

Now to access these values within our plugin we need to do the following:-

Cast it into a DynamicEntity
DynamicEntity preLead = (DynamicEntity)context.PreEntityImages[“LeadImage”];
DynamicEntity postLead = (DynamicEntity)context.PostEntityImages[“LeadImage”];

For getting the id of the entity ( unlike crm 3.0 we don;t have entity context over here )

Key keyLeadId = (Key)postLead.Properties[“leadid”];
string leadId = keyLeadId.Value.ToString();

For lookup field use this line of code

Lookup lkpLobPre = (Lookup)preLead.Properties[“new_linesofbusinessid”];
strPreLobGuid = lkpLobPre.Value.ToString();
Lookup lkpLobPost = (Lookup)postLead.Properties[“new_linesofbusinessid”];
strPostLobGuid = lkpLobPost .Value.ToString();

For owner field

Owner ownerLead = (Owner)postLead.Properties[“ownerid”];
strPostOwnerGuid = ownerLead.Value.ToString();

For money field

CrmMoney estimatedvalue = (CrmMoney)postLead[“new_expectedrevenue”];
strExpectedRevenue = estimatedvalue.Value.ToString();

For string field

String geoName = (String)postLead[“new_geographyidname”];

For picklist field

Picklist leadqualitycode = (Picklist)postLead[“leadqualitycode”];
strRating = leadqualitycode.name;

Unable to cast object of type ‘Microsoft.Crm.Sdk.Moniker’ to type ‘Microsoft.Crm.Sdk.DynamicEntity’

I was writing my first callout ( plugin) for CRM 4.0 when i recieved this error.

I realized that this was because of this line of code in my plugin

public void Execute(IPluginExecutionContext context)
{

DynamicEntity entity = (DynamicEntity)context.InputParameters.Properties[“Target”];

……

For Create and Update message there was no problem.

Problem started coming when i registered the step for Assign message.

So modified the code as following

DynamicEntity entity = null;
if (context.InputParameters.Properties.Contains(“Target”) &&
context.InputParameters.Properties[“Target”] is DynamicEntity)
{
// Obtain the target business entity from the input parmameters.
entity = (DynamicEntity)context.InputParameters.Properties[“Target”];
}

For Assign Message used the following line of code

if (context.MessageName == “Assign”)
{
Moniker myMoniker = null;
if (context.InputParameters.Properties.Contains(“Target”) &&
context.InputParameters.Properties[“Target”] is Moniker)
{
// Obtain the target business entity from the input parmameters.
myMoniker = (Moniker)context.InputParameters.Properties[“Target”];
}

myMoniker.Name –> Gave the name of the entity

myMoniker.Id –> Gave the id of the entity

Retrieving Members of Team – CRM

Hi,

We can make use of the following function for retrieving the members of a particular team

It takes as parameter instance of a ICrmService(CRM 4.0) or CrmService (CRM 3.0) and the guid of the team and returns an arraylist of of all the members found in the team

public ArrayList GetMembersOfTeam(ICrmService service, String TeamID)
{
// We want the guid of the system users in the team
ColumnSet cols = new ColumnSet(new String[] { “systemuserid” });
// We need to make use of RetrieveMembersTeamRequest class for that
RetrieveMembersTeamRequest rmtRequest = new RetrieveMembersTeamRequest();
// Converting the string TeamID to guid
Guid headGuid = new Guid(TeamID);

rmtRequest.EntityId = headGuid;
rmtRequest.MemberColumnSet = cols;

RetrieveMembersTeamResponse retrieved = (RetrieveMembersTeamResponse)service.Execute(rmtRequest);

// using generic businessEntity list
List<BusinessEntity> sysResult = retrieved.BusinessEntityCollection.BusinessEntities;

// for CRM 3.0
// BusinessEntity[] sysResult = retrieved.BusinessEntityCollection.BusinessEntities;

ArrayList userGuid = new ArrayList();

foreach (BusinessEntity be in sysResult)
{
systemuser user = (systemuser)be;
userGuid.Add(user.systemuserid.Value.ToString());
}
return userGuid;
}

Calling a asp.net webservice from an asp page

Say we have created a simple web service like this

[WebMethod]
public string Hello(String name) {
return “Hello “+name ;
}

Now we want to call the web service from inside our asp page,

for this we can make use of the following code

<%
Dim myPostData
Dim name
name=”Mickey Mouse”
myPostData=”name=” & name
Dim xmlhttp
Dim postUrl
postUrl = “http://servername/MyService/Service.asmx/Hello”
Set xmlhttp = server.Createobject(“MSXML2.XMLHTTP”)
xmlhttp.Open “POST”,postUrl,false
xmlhttp.setRequestHeader “Content-Type”,”application/x-www-form-urlencoded”
xmlhttp.send strWebServideDetails
Response.Write(“<b>This is the message i recieved</b>” +xmlhttp.responseText)
