I. Why is a strange string automatically generated in the URL during the vs2010 test?

Run: localhost/myclass. aspx
Press Enter: localhost/(sviecu555gar4v55ogmacsfg)/myclass. aspx

A: This is how ASP. NET records sessions. If cookies are disabled on the client, the session ID is recorded at the URL location.

You can remove cookieless = true from the Web. config configuration file.

2. How can I display the HTML code in the database to the page after I use kindeditor to save the content to the data?

A:

Add the. ASPX page

<div id="divBody" runat="server"></div>

Then add

Divbody. innerhtml = "the HTML code you want to display ";

3. When the button control is used, the page redirection of onclick cannot be executed.

A: Because the type of the button control is submit, there is a page Redirection action (refresh on this page), so a conflict is generated.

<Asp: button id = "btn_send" runat = "server" text = "send" onclick = "msgsend_click"/>

The solution is to replace the button control with HTML input.

<Div id = "btn_send" runat = "server" text = "send" onclick = "msgsend_click"/>

4. Save the HTML code to the local Word Document

// Call this method to export it as a Word document, and the input parameter is this. page public static void getwordfile (string msgname, string msg_content, system. web. UI. page) {httpresponse resp = page. response; resp. clear (); resp. buffer = true; resp. contentencoding = system. text. encoding. getencoding ("gb2312"); resp. addheader ("content-disposition", "attachment; filename =" + msgname); resp. contenttype = "application/MSWord"; msg_content = "<HTML xmlns = 'HTTP: // www.w3.org/5o/xhtml'>" + msg_content + "

Msg_content is the HTML code to be output.
