    Hi,


    Maybe outlook uses a strange uri format for the images that rtb does not understand.  Take a look at the emails in raw mode.

    Displaying emails from gmail and yahoo mail works because the uris are from the internet.  Outlook on the other hands uses cid: uris to show images embedded in the email itself.  You need to extract or load those images and patch up the rtb document so that uris point to the correct location.

    Hi,


    Thanks for your reply.


    But how to extract pictures from the image tag


    <img width=180 height=270 id="_x0000_i1028 "rn src="cid:image001.png@01CC036A.49E36DC0">


    or from outlook server.

    Hi Gaurang,


    You need to intercept the HTML import. For example:


    richTB.HtmlFilter.ConvertingHtmlNode += OnConvertingHtmlNode;


    Please take a look to the sample RichTextBoxSamples2010, DemoRichTextBox.xaml.cs.


    Hope this helps!

    Hi,


    Thanks for your reply.


    My problem is that when I received email from Outlook with embedded image that time it does not seen. So I think first I should download the image and then using your above help I need to replace src so it will display.


    But I do not have any idea to download image from the image tag when I received this type of embedded image into email body.


    Please tell me if you have any idea or link so I can solve my problem.


    Thanks,

    Is it a stream?


    You can create an image from a stream in Silverlight, in the following way:


    blogs.silverlight.net/.../silverlight-tip-of-the-day-92-how-to-load-images-from-a-stream.aspx


    Obviously, the image format should be supported by the Silverlight framework too. If not, you need to convert it somehow in the server or create your custom Image Decoder. We provide one for GIF Images in C1.Silverlight.Imaging.

    Hi,


    Thanks for your reply.


    techhelp.santovec.us/decode.htm


    www.outlookcode.com/.../htmlimg.htm Using this link also helpful for me to understand MIME and outlook embedded image.


    Now I can download embedded images to Server side from MIME (I used Chilkat.dll for email).


    Below is sample code for downloading image and it is working.


    Chilkat.Mime mime = new Chilkat.Mime();


    mime.UnlockComponent("Anything for 30-day trial.");


    mime.LoadMime(email.GetMime());


    for (int x = 0; x < mime.NumParts; x++)


    {


    if (mime.GetPart(x) != null)


    {


    if (email.GetRelatedContentType(x) != null)


    {


    string[] str = email.GetRelatedContentType(x).ToString().Split('/');


    if (str.Length > 1)


    { //mime.GetPart(x).SaveBody(AppDomain.CurrentDomain.BaseDirectory.ToString() + "ClientBin\img\" + email.GetRelatedFilename(x) + "." + str[1]); //output : F:\XYZ\Com.Server.Web\ClientBin\img\image001.gif


    string path = System.Web.HttpContext.Current.Server.MapPath("~/img");


    mime.GetPart(x).SaveBody(path + email.GetRelatedFilename(x) + "." + str[1]);


    }}}}


    I tried to get image path these way (I used ComponentOne C1RichtextBox)


    1) string hostName = Application.Current.Host.Source.Host;


    2) string serverPath = AppDomain.CurrentDomain.BaseDirectory;


    3) string url = App.Current.Host.Source.ToString


    Replace old path to new path this way.


    void OnConvertingHtmlNode(object sender, C1.Silverlight.RichTextBox.Documents.ConvertingHtmlNodeEventArgs e)


    {


    var element = e.HtmlNode as C1.Silverlight.RichTextBox.Documents.C1HtmlElement;


    if (element != null && element.Name == "img")


    {


    string src;


    if (element.Attributes.TryGetValue("src", out src) && src.StartsWith("cid:"))


    {


    src = src.Remove(0, 4);


    string[] temp = src.Split('@');


    string path = System.IO.Path.GetDirectoryName(App.Current.Host.Source.ToString().Remove(App.Current.Host.Source.ToString().Length - 17)).Replace("\", "//") + "/Images/";


    element.Attributes["src"] = path + App.CurrentUser.UserId.ToString() + temp[0];


    } } }


    Thanks,

    Great. Thanks for sharing the solution.


    BTW, I almost use Chilkat component a few years ago, while trying to build an email client. Then I dismissed the project. Is it good?

    On the File tab, choose Options > Trust Center.
    Under Microsoft Outlook Trust Center, click Trust Center Settings.
    Clear the Don't download pictures automatically in HTML e-mail messages or RSS items check box.
