• "System.Web.HttpContext cannot be serialized because it does not have a parameterless constructor."

  I've created a web service that other sites can use to store errors in my database. They can then come to my site to view their errors, search through errors, filter errors, etc. However, I'm getting the following error for my web service: System.Web.HttpContext cannot be serialized because it does not have a parameterless constructor. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the

  [quote user="BryianTan"] hi, Have you try to place a break point on line 02 and debug it? Thanks, Bryian tan [/quote] Unfortunately, this is only happening on the production server, so I can't debug it.

• Only arguments that can be evaluated on the client are supported for the String.Contains method

  public static void MyFunction(MyErrorClass err) { var query = from filter in DataContext.ErrorFilters select filter; query = query.Where(f => err.ErrorMessage.Contains(f.ErrorMessage)); List<ErrorFilter> filters = query.ToList(); //...more code } So I'm having some issues with the above code, and I'm getting the error from the subject line at the line with "query.ToList()". Here's what I'm trying to do: First off, I have a custom error class, MyErrorClass. Whenever

• Creating a custom API

  I'm creating a site, and I need to create a basic API. Unfortunately I have no idea where to start. My site will basically keep track of errors from other users' ASP.NET sites, and they can filter through them, search, etc. I need to create an API, where the user can insert a few lines of code in the Application_Error event in the global.asax file, and it will pass an exception object to my site to be stored. It's the communicating between their site and my site that I don't understand

• ASP.NET Membership - using different tables

  So when I'm using the Login controls and the MembershipUser and Roles classes, all users are automatically in the ASP.NET tables in the database: aspnet_Users, aspnet_Roles, aspnet_Membership, etc. Well I don't really like how some of the tables are used, I don't need some of the columns (for instance, I don't need the Description column in the aspnet_Roles table), and I just simply don't like the table names. I also hate that there is a lot going on behind the scenes that I'm

• Menu control in Safari 4.0.3

  So I'm using a Menu control on my page, and it has dynamic items that should drop down when you hover over a menu item. This works in all browsers except for Safari 4.0.3. I've looked around and there seem to be several solutions to this problem: 1. Add this code to the Page_Load event: if (Request.UserAgent.IndexOf("AppleWebKit") > 0) { Request.Browser.Adapters.Clear(); } 2. Add this code to the Page_PreInit event: if (Request.UserAgent.IndexOf("AppleWebKit") >

• Excel Interop - setting formula for a cell

  I'm create an excel spreadsheet dynamically using Excel Interop. I have two cells in a single column. The first cell contains this formula: "=(F1+G1)" I would like to set the formula for the second cell to be the same as the first cell, but have F2 and G2 instead of F1 and G1. This needs to be dynamic. Here's what I have now: Excel.Range rngCurrentCell = (Excel.Range)ws.Cells[row,col]; Excel.Range rngPrevRow = (Excel.Range)ws.Cells[row - 1, col]; rngCurrentCell.Formula = rngPrevRow
