CRM 2016 eMail Attachment

Posted on by IwishIknow 247

I have spent 2 weeks trying to attach a PDF to an email with no success.  I know I am missing something very simple but cannot find a solution. I've tried every solution i could google no success.

Step 1 Generate the PDF from HTML - Completed

Step 2 Read/Retrieve the PDF - Completed

   var pdflocation = pdfpath + printContents + '.pdf';
    jQuery.get(pdflocation, function(data) {
            var str = base64ToArrayBuffer(data);
            console.log(btoa(str));
    });

Step 3 convert to bytearry - Fail - Fail - Fail

         function base64ToArrayBuffer(data) {  
/*
            var reader = new FileReader();
            reader.readAsArrayBuffer(data);
            var arrayBuffer = reader.result
            var bytes = new Uint8Array(arrayBuffer);
    
            //var buffer =  atob(data);
            var buffer = new ArrayBuffer( data.length );
            //var buffer = window.btoa(escape(encodeURIComponent( data )));
            //var buffer = encodeURIComponent( data );
            var len = buffer.length;
            var bytes = new Uint8Array( len );
*/
              
            var buffer = new ArrayBuffer( data.length ), // res is this.response in your case
                bytes   = new Uint8Array( buffer ),
                len    = bytes.length,
                fromCharCode = String.fromCharCode,
                i, s, str;    
            str = "";


                 for ( i = len; i--; ) {
                   bytes[i] = data[i].charCodeAt(0);
                 }

                 for ( i = 0; i < len; ++i ) {
                   str += fromCharCode( bytes[i] );
                 }    
/*
*/
/*

                 for ( i = 0; i < len; ++i ) {
                   //str += fromCharCode( data[i].charCodeAt(0) & 0xff );
                   bytes[i] += buffer.charCodeAt(i);
                 }
*/                 
            //for (var i = 0; i < len; i++)        {
              //  bytes[i] = buffer.charCodeAt(i);
            //}

            return bytes.buffer;
        }

Any and all help would be appreciated.

    Try this,

    function _arrayBufferToBase64(buffer) { // Convert Array Buffer to Base 64 string

    var binary = '';

    var bytes = new Uint8Array(buffer);

    var len = bytes.byteLength;

    for (var i = 0; i < len; i++) {

    binary += String.fromCharCode(bytes[i]);

    }

    return window.btoa(binary);

    }

    which browser are you using, there is an issue with IE 10 it seems, workaround is as follows

    I attempted 2 ways in chrome and IE

    function _arrayBufferToBase64(buffer) { // Convert Array Buffer to Base 64 string

    var binary = '';

    //var bytes = new Uint8Array(buffer);

    var bytes = new Uint32Array(buffer);

    var len = bytes.byteLength;

    for (var i = 0; i < len; i++) {

    binary += String.fromCharCode(bytes[i]);

    }

    return window.btoa(binary);

    }        

           function CreateEmailAttachment(results) {            

              var aFileParts = [document.documentElement.innerHTML];

              var oMyBlob = new Blob([newDoc]); // the blob

              //Email attachment parameters

              var activitymimeattachment = Object();

              activitymimeattachment.ObjectId = Object();

              activitymimeattachment.ObjectId.LogicalName = "email";

              activitymimeattachment.ObjectId.Id = results.ActivityId;

              activitymimeattachment.ObjectTypeCode = "email",

              activitymimeattachment.Subject = "File Attachment";

                 var pdflocation = pdfpath + printContents + '.pdf';

    /* get file using ajax both binary  and string              

              $.ajax({

                url: pdflocation,

                dataType: "string",

                processData: false,

                success: function(result){

                    var buffer = new ArrayBuffer( result.length );

                    var len = buffer.length;

                    var bytes = new Uint8Array( buffer );

                    for (var i = 0; i < len; i++)        {

                      bytes[i] = buffer.charCodeAt(i);

                    }

                    var str = _arrayBufferToBase64(result)

               // do something with binary data

                    activitymimeattachment.Body =  str;

                },

                error: function() { alert('Failed!'); }

              });

    */

    /* jQuery

    Get the base64 output and try to test in some online tester such as

    www.motobit.com/.../base64-decoder-encoder.asp

    The following code works accross almost all browsers for me

       var selectedFile = document.getElementById("inputFile").files;

       //Check File is not Empty

       if (selectedFile.length > 0) {

           // Select the very first file from list

           var fileToLoad = selectedFile[0];

           // FileReader function for read the file.

           var fileReader = new FileReader();

           var base64;

           // Onload of file read the file content

           fileReader.onload = function (fileLoadedEvent) {

               base64 = fileLoadedEvent.target.result;

               // Print data in console

               console.log(base64);

           }

    Hi,

    Just replace the code below and see if it works.

     function base64ToArrayBuffer(data) {
    var binary_string =  window.atob(data);
    var len = binary_string.length;
    var bytes = new Uint8Array( len );
    for (var i = 0; i < len; i++)        {
        bytes[i] = binary_string.charCodeAt(i);
    }
    return bytes.buffer;
}

    Hope this helps.

    Please replace the line as follows.

    var binary_string =  atob(data);
