Hi Prasad,

NO NO NO, the blog post from Benoît and I is about how to create a NEW module from scratch, not to modify the Store module! You have to read this post and follow exactly my advices. THIS IS REALY IMPORTANT or I can't help. Remember you told me your are a beginner with ASP.NET, DotNetNuke and module dev. I understand that your are tired, but if you do not follow my advices what can I do?

Hi Gilles,

Finally I got the solution.Now my project is compiling and applying my changes in to the .dlls.
Thank you very very much for your genuine support.Really you and Benoit helped me a lot.


Actually I wanted to do this. I have to work some other database and they are saving images in to the database in image format as byte data. I have to read it and show it as an image. They are updating my DNN database.But Images are in image format. Then I have to read that byte data and have to show it as an image. Anyway I created a token and try to show it as a image control in ProductDetails page according to your (Gilles) instructions. I tested a new token with text control and It is working.But I can not do it for the image control.

I did my changes in DotNetNuke.Store.WebControls project and ProductDetail.ascx.cs page under this code.

private Control processToken(string tokenName)
        {
            switch (tokenName)
            {
                case "IMAGE":


This is what I have added as my new method.But there is an issue with the Image type what I have used.This is my code.

case "IMAGEDB":
                    //Label lbltest = new Label();
                    //lbltest.Text =  Localization.GetString("test.Test", this.LocalResourceFile);
                    ////lbltest.Text = string.format(Localization.GetString("WidthText", this.LocalResourceFile), productInfo.ProductWidth.ToString(Localization.GetString("Widthformat", this.LocalResourceFile), Localformat));
                    //lbltest.CssClass = "StoreCategoryName";
                    //return lbltest;
                    byte[] img;
                     Image returnImage;
                    if (!showThumbnail || String.IsNullOrEmpty(productInfo.ProductImage))
                    {
                        // No control in this case
                        return null;
                    }
                    else
                    {
                        string imageAlt = productInfo.Summary;
                        if (imageAlt == string.Empty)
                            imageAlt = Localization.GetString("ImageAlt.Text", LocalResourceFile);
                       
                        //get the image id from the url
                        string ImageId = Request.QueryString["img"];

                        //build our query statement
                        string sqlText = "SELECT img_data, img_contenttype FROM Image WHERE img_pk = 1";

                        SqlConnection connection = new SqlConnection(ConfigurationSettings.AppSettings["TestingSiteSqlServer"].ToString());
                        SqlCommand command = new SqlCommand(sqlText, connection);

                        //open the database and get a datareader
                        connection.Open();
                        SqlDataReader dr = command.ExecuteReader();
                        if (dr.Read()) //yup we found our image
                        {
                            Response.ContentType = dr["img_contenttype"].ToString();
                            Response.BinaryWrite((byte[])dr["img_data"]);

                            img = (byte[])dr["img_data"];

                            MemoryStream ms = new MemoryStream(img);
                            returnImage =  Image.FromStream(ms);
                        }
                        return returnImage;
                        connection.Close();

                        if (InList)
                        {
                            StringDictionary replacements2 = new StringDictionary();
                            replacements2.Add("ProductID", productInfo.ProductID.ToString());

                            HyperLink lnkImage = new HyperLink();
                            lnkImage.NavigateUrl = catalogNav.GetNavigationUrl(replacements2, detailID);
                            lnkImage.ToolTip = imageAlt;
                            lnkImage.CssClass = "StoreProductLinkImage";
                            lnkImage.Controls.Add(returnImage);
                            return lnkImage;
                        }
                        else
                        {
                            return returnImage;
                        }
                    }

My problem with Image.FromStream . It is not supporting inside the code.

I know you are very busy with your works. I am really sorry If I am disturbing you. If it is possible to help me please let me know what I have done wrong or have I done it in correct way. I am really appreciate what you have done for the community up to now.

Thank you very much.

Hi Prasad,

1) I have already explained that you have to create your own token and to create a new page like ImageDB.aspx to replace the Thumbnail.aspx page. Your code to read the image from the db should be in the ImageDB.aspx page NOT in the ProductDetail.cs! Look at the IMAGE token to discover how it work. Basicaly the token return an image control with an url like http://yourdomain/DesktopModules/Store/Thumbnail.aspx?IP=(image path)&IW=(imagewidth)&portalID=(your portal ID). When the page is displayed, the client browser call this url to retreive the image. You have to create your own url to call your ImageDB.aspx page with your own parameters. Moreover, you have to understand that I CAN'T write your own code because it's higly time consuming and too specific to your needs. Please stop to use my email to request support, I do not offer this kind of personal support for free because it's NOT related to the Store module but to YOUR needs.

2 and 3) For questions related to dnn, please ask in the "Install It!" forum.

4) There is NO version 02.02.00! The last beta version is 02.01.17. Some users have installed the beta on production, but I can't give you any garanty about the beta versions.

5) It's normal! You can't use the "Edit & Continue" method because the solution use the WAP model not the WSP model. You should read this "Introduction to Web Application Projects" at MSND to understand what a WAP project is. There are plentry of posts on the Internet too, like this one.
