In our previous article we explained how to get an image from Notes using OData endpoints. In this article we will explain how to create a HTML web resource and use our JavaScript method to get and display the image. We need to implement the following two steps:

· Create HTML page

· Deploy HTML page and SDK.REST.js using web resource

Create HTML page

Create a HTML page using a HTML editor. Use the following code for the HTML page:

<html lang="en-us"><head>
//Reference clientglobalcontest.js to get context information
<script src="../ClientGlobalContext.js.aspx"></script>
//add SDK.Rest.js reference
<script type="text/javascript" src="SDK.REST.js"></script>
<script type="text/javascript">
//check if document is loaded or not
var imgControl = document.createElement("IMG");
//Check if documented loaded fully
document.onreadystatechange = function () {
if (document.readyState == "complete") {
getnotesImages();
}
}
//this function is used to get image from notes
function getnotesImages()
{ //get regarding object id
var regardingObjectId=window.parent.Xrm.Page.data.entity.getId();
//assign notes entity name
var entitySchemaName="Annotation";
var odataQuery = "?$top=1&$select=AnnotationId,DocumentBody,MimeType&" +
"$filter=ObjectId/Id eq guid'" + regardingObjectId +
"' and IsDocument eq true and startswith(MimeType,'image/') ";
//call retrieveMultipleRecords method in SDK.REST javascript script library
SDK.REST.retrieveMultipleRecords(entitySchemaName, odataQuery, getnotesImagesCallback, function (error) { alert(error.message); }, function(){});
}
//process callbanck result
function getnotesImagesCallback(resultSet)
{
if (resultSet.length > 0) {
var mimeType = resultSet[0].MimeType;
var body = resultSet[0].DocumentBody;
imgControl.src="data:" + mimeType + ";base64," + body;
document.getElementById('imagediv').appendChild(imgControl);
}
}
</script>
<meta charset="utf-8"></head><body style="zoom: 1;">
<div style="width: 100px;" id="imagediv"></div>
</body></html>

Deploy HTML page and SDK.REST library using web resource

Use following procedure to deploy a HTML page and SDK.REST library in Microsoft CRM.

Navigate to Settings -> Customization-> Customize the System from the top navigation bar
Navigate to Components -> Web Resources-> New
Fill in the details as in the following screen:

Click on the browse button and select your HTML web resource.
Click on Save and then Publish
Navigate to Components -> Web Resources-> New
Fill in the details as in the following screen:

Click on browse and select SDK.REST.js from Microsoft CRM SDK

Note: Please refer to my previous article for the SDK.REST.js location.

Now we can place our HTML web resource in the account entity form by navigating to Insert -> Web Resource options. Save your changes and then publish the account entity form.
