StringBuilder customerDoc = new StringBuilder();
customerDoc.Append("<Method ID='1' Cmd='New'>");
customerDoc.Append("<Field Name='Name'>" + Name + "</Field>");
customerDoc.Append("<Field Name='Age'>" + age + "</Field>");
customerDoc.Append("<Field Name='City'>" + city + "</Field>");
customerDoc.Append("<Field Name='Country'>" + country + "</Field>");
customerDoc.Append("</Method>");
XmlDocument xDoc = new XmlDocument();
XmlElement xBatch = xDoc.CreateElement("Batch");
xBatch.SetAttribute("OnError", "Continue");
xBatch.InnerXml = sb_method.ToString();
XmlNode xn_return = sharePoint.listsObj.UpdateListItems(ConfigurationManager.AppSettings["SaveCustomer"].ToString(), xBatch);
As you can see I am using a stringbuilder which isn't ideal so I wonder what I should use instead to create an XML string?

View 2 RepliesI am working on a website, using C# with a SQL backend. I'm using the Varbinary data type to store my images because the Image data type is eventually going away. I got the images into the DB and can pull them back out to display on the website. My question is how can I put the images from the DB into an Image control on the website? The images will be different sizes, so I need to keep them confined in one space on the site. I also need to randomly display the images, one at a time, on the website. The user needs to be able to hit the Next button to see the next image when they are ready. The user will only view the images, not make any changes and send data back to the DB.
Since the image will be confined within the image control, how can I allow the user to click on the image and open in a new window? The image needs to be bigger to allow the user to see more detail. Or would it be easier to allow the user to zoom in on the image within the current window?I am using VWD Express, C# 2010 Express & SQL 2005 Express.
I have image tag in datalist that width=100px Hight=100px
And I have several image in my database with different size

E.g.: if my image be 300*500 when it show in image tag it stretch my image from width .
I want if my image size be reduceو it reduce width&Hight deppending to real size of image don't stretch it.

View 2 Repliesanyone knows how to replace a html tag in a string with specific characters:
e.g.
string s1 = "<span style="italic">inluding <span style="bold">other</span> tags </span>";
string s2 = "<span style="italic">inluding </span><span style="bold">other tags </span>";
i want to replace "span" with "bold" to "bOpen" and "bClose" and to replace "span" with "italic" to "iOpen" and "iClose" in both c# and javascript.
i did use regular expression to do that: res = Regex.Replace(res, ".*?", replaceHtmlBold); but it cant match the nested tag and none-nested tag at the same time.
