vb.net - Custom Checkbox list control Error in asp.net. "startIndex cannot be larger than length of string" -

I'm creating a custom checkbox control to add a div after each box in a checkboxlist. The class is down

Importing Systems Web. UI. WebControls Importing Systems Component MODEL Importing System Globilization Public Class Michekbox List Checkbox enforces checkboxeslink in the Inbox. IREAPT Infosource Protected Override Subordinate Item (ByVal Item Type List Type, By Behal Replate Index Integer, ByVal repeatInfo as RepeatInfo, ByVal Author HtmlTextWriter) Writer.WriteBeginTag (" as input ") writer.WriteAttribute (" type "," box ") writer.WriteAttribute (" name ", UniqueID) writer.WriteAttribute (" ID ", (ClientID & amp;" _ ") + repeatIndex.ToString ( NumberFormatInfo.Invariant Info)) writer.WriteAttribute ("value", item (repeatIndex) .Value) Dim attrs as System.Web.UI.AttributeCollection = item (repeatIndex).

But I get an error when I use it in a page and ask to save. The error is:

The starting index can not be longer than the string length. Parameter Name: startIndex Description: An uncontrolled exception occurred during the execution of the current web request. For more information about error and where this code has originated, review the stack trace

Any ideas?

"itemprop =" text ">

Place a breakpoint on your override renderItem function declaration. Start your project using VS debugging mode and what variables are set and what to find out I think you are starting somewhere on an empty string. Remember, arrays and such launches 0

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

What is expire header and how to achive them in ASP.NET and PHP? -

I have examined the performance statistics of my website today. I have received a warning (or error may occur) that is given below Add Terminal Headers Here are 15 static components without a 15-futures end date * (no end) Http://www.example.com/video/css/global.css * (no time limit) http://www.example.com/video/js/global.js * (no expiration ) Http: //www.example.com/video/images/main-bg.png what it means and how to achieve it both in PHP and ASP.Net. I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for. Is Is there any harm to using PHP? $ time = time () + 3 * 24 * 60 * 60; // 3 day headings ('End:'. GMDAT ('D, D MYH: i: s \ g \ m \ t',

sql server - How can I determine which of my SQL 2005 statistics are unused? -

-
After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
