• Where could I get the information about the in-memory layout info of .NET Object Model?

  - by smwikipedia

  I want to know the in-memory representation of .NET constructs such as "interface", "class", "struct", etc. There's an excellent book for C++ object model - <Inside the C++ Object Model by Stanley. Lippman, I want a similar book for .NET and C#. Could someone provide some hints about books and articles? I have read about the "Drill Into .NET Framework Internals to See How the CLR Creates Runtime Objects" Anything more? If this info is not publicly avaialble. Shared source one like Mono or Shared Source CLI could be an option. Many thanks.

• Organization moving from ASP.NET to WebLogic - training recommendations?

  - by frankadelic

  My organization previously used ASP.NET for web projects. They are now migrating to WebLogic/JEE for all future web projects. My experience as a Lead Developer / Architect is totally with .NET projects. I want to get ramped up on WebLogic/JEE, so I can contribute to future projects. Any training/certification suggestions for WebLogic/JEE, in a 6-month time frame? Assume that I will need to fund my own training, and I am working full time. So, money and time are limited.

• Modify Gridview as it's being rendered through javascript

  - by JonF

  I'm trying to modify a field in each row of my gridview as it is rendered. I need to modify it with client side Javascript. I'm somewhat new to asp.net, but I think I should be doing something with clientscriptmanager. I came up with a simple scenario which is basically what I want to do to avoid getting bogged down in the details. If I could accomplish the following I could accomplish my goal. Say I have a grid view of names and salaries. I want to double each persons salary before displaying it. Obviously I can do it in the code behind, but due to the nature of the more complex actual thing I'm doing, I need to do it in javascript <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" onrowdatabound="GridView1_RowDataBound" > <Columns> <asp:BoundField HeaderText="Full Name" DataField="Name" ></asp:BoundField> <asp:BoundField HeaderText="Salary" DataField="Salary" /> </Columns>

• This .NET code snippet will NOT actually create a cookie, right?

  - by Ryan

  I just realized that this cookie is not showing up like it should, and I checked the code which was not written by me but I am pretty sure that this is NOT enough to create a cookie right?? public static void CreateSSOCookies(string tokenID) { System.Web.HttpContext.Current.Response.Cookies["ssocookies"].Domain = System.Web.HttpContext.Current.Request.ServerVariables["SERVER_NAME"].ToString().ToLower(); System.Web.HttpContext.Current.Response.Cookies["ssocookies"].Value = tokenID.ToString(); System.Web.HttpContext.Current.Response.Cookies["ssocookies"].Path = "~/"; System.Web.HttpContext.Current.Response.Cookies["ssocookies"].Expires = DateTime.Now.AddDays(7); } If it does work, where is the cookie then? Is the cookie name 'ssocookies' ?

• Programmatically triggering events in Javascript for IE using jQuery

  - by Dan Herbert

  When an Event is triggered by a user in IE, it is set to the window.event object. The only way to see what triggered the event is by accessing the window.event object (as far as I know) This causes a problem in ASP.NET validators if an event is triggered programmatically, like when triggering an event through jQuery. In this case, the window.event object stores the last user-triggered event. When the onchange event is fired programmatically for a text box that has an ASP.NET validator attached to it, the validation breaks because it is looking at the element that fired last event, which is not the element the validator is for. Does anyone know a way around this? It seems like a problem that is solvable, but from looking online, most people just find ways to ignore the problem instead of solving it. To explain what I'm doing specifically: I'm using a jQuery time picker plugin on a text box that also has 2 ASP.NET validators associated with it. When the time is changed, I'm using an update panel to post back to the server to do some things dynamically, so I need the onchange event to fire in order to trigger the postback for that text box. The jQuery time picker operates by creating a hidden unordered list that is made visible when the text box is clicked. When one of the list items is clicked, the "change" event is fired programmatically for the text box through jQuery's change() method. Because the trigger for the event was a list item, IE sees the list item as the source of the event, not the text box, like it should. I'm not too concerned with this ASP.NET validator working as soon as the text box is changed, I just need the "change" event to be processed so my postback event is called for the text box. The problem is that the validator throws an exception in IE which stops any event from being triggered. Firefox (and I assume other browsers) don't have this issue. Only IE due to the different event model. Has anyone encountered this and seen how to fix it? I've found this problem reported several other places, but they offer no solutions: jQuery's forum, with the jQuery UI Datepicker and an ASP.NET Validator ASP.NET forums, bug with ValidatorOnChange() function

• Is it normal that .Net combobox postback always contains data items?

  - by BlueFox

  I have a dynamically populated ComponentArt:ComboBox with Autopostback property set to true. So every time the selection changes, a postback to server would be fired. Everything seems to work fine except that the lists of all available items are also posted back to the server. from Firebug: ComboBox1_Data %3Cr%3E%3Cc%3E%3Cr%3E%3Cc%3E%3Cr%3E%3Cc%3EText%3C%2Fc%3E%3Cc%3E150%20Mile%20House%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3Cc%3E%3Cr%3E%3Cc%3E%3Cr%3E%3Cc%3EText%3C%2Fc%3E%3Cc%3EAach%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3Cc%3E%3Cr%3E%3Cc%3E%3Cr%3E%3Cc%3EText%3C%2Fc%3E%3Cc%3EAachen%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3Cc%3E%3Cr%3E%3Cc%3E%3Cr%3E%3Cc%3EText%3C%2Fc%3E%3Cc%3EAaheim%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3Cc%3E%3Cr%3E%3Cc%3E%3Cr%3E%3Cc%3EText%3C%2Fc%3E%3Cc%3EAakrehamn%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3Cc%3E%3Cr%3E%3Cc%3E%3Cr%3E%3Cc%3EText%3C%2Fc%3E%3Cc%3EAalbeke%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3Cc%3E%3Cr%3E%3Cc%3E%3Cr%3E%3Cc%3EText%3C%2Fc%3E%3Cc%3EAalen%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3Cc%3E%3Cr%3E%3Cc%3E%3Cr%3E%3Cc%3EText%3C%2Fc%3E%3Cc%3EAalst%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3Cc%3E%3Cr%3E%3Cc%3E%3Cr%3E%3Cc%3EText%3C%2Fc%3E%3Cc%3EAalter%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3Cc%3E%3Cr%3E%3Cc%3E%3Cr%3E%3Cc%3EText%3C%2Fc%3E%3Cc%3E%C3%84%C3%A4nekoski%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3Cc%3E%3Cr%3E%3Cc%3E%3Cr%3E%3Cc%3EText%3C%2Fc%3E%3Cc%3EAarau%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3Cc%3E%3Cr%3E%3Cc%3E%3Cr%3E%3Cc%3EText%3C%2Fc%3E%3Cc%3EAarberg%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3Cc%3E%3Cr%3E%3Cc%3E%3Cr%3E%3Cc%3EText%3C%2Fc%3E%3Cc%3EAarbergen%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3Cc%3E%3Cr%3E%3Cc%3E%3Cr%3E%3Cc%3EText%3C%2Fc%3E%3Cc%3EAarburg%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3Cc%3E%3Cr%3E%3Cc%3E%3Cr%3E%3Cc%3EText%3C%2Fc%3E%3Cc%3EAarebakken%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3Cc%3E%3Cr%3E%3Cc%3E%3Cr%3E%3Cc%3EText%3C%2Fc%3E%3Cc%3EAarschot%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3Cc%3E%3Cr%3E%3Cc%3E%3Cr%3E%3Cc%3EText%3C%2Fc%3E%3Cc%3EAarsele%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3Cc%3E%3Cr%3E%3Cc%3E%3Cr%3E%3Cc%3EText%3C%2Fc%3E%3Cc%3EAartrijke%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3Cc%3E%3Cr%3E%3Cc%3E%3Cr%3E%3Cc%3EText%3C%2Fc%3E%3Cc%3EAartselaar%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3Cc%3E%3Cr%3E%3Cc%3E%3Cr%3E%3Cc%3EText%3C%2Fc%3E%3Cc%3EAavasaksa%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3C%2Fr%3E%3C%2Fc%3E%3C%2Fr%3E ComboBox1_Input Aalst ComboBox1_SelectedIndex 7 As most my clients are using slow connections, this amount of postback has a huge impact on their user experience. Since I'm storing the viewstates in session already, there's really no need for any of the component to restore states from the client. So I'm wondering if this is normal for ComponentArt:ComboBox to do this and not other controls, or this is the normal way of doing things?

• Prevent bubbling without Jquery

  - by mariki

  When I move mouse over the container panel, the child panel is displayed but as soon as i move mouse over the child panel, the mouseout event is triggered and panel get hidden. This is simplified version of my code because panels are located inside gridview and therefore i can't use document.getElementById("panelchild") as it is (the js will get the specific id latter), but for now i want to make it work for this simple case. This is the partial script: <script type="text/javascript"> function ShowPanel(e) { // e = e || window.event; // var evtSrc = e.target || e.srcElement; var panel = document.getElementById("panelchild") if (panel.style.display == "none") panel.style.display = ""; else panel.style.display = "none"; } </script> This is the markup: <asp:Panel id="panelContainer" runat="server" onmouseover="ShowPanel(event)" onmouseout="ShowPanel(event)" > <asp:HyperLink ID="lnkTitle" runat="server" style="float:left;margin-right:10px;" Text="This is title" NavigateUrl="www" /> <asp:Panel id="panelchild" runat="server" style="display:none" > <a id="A1" href="javascript: void(0);" style="text-decoration: none;"> <img src="mylocalsite/images/Misc_Edit.gif" style="border:0px;float:left;" /> </a> </asp:Panel> </asp:Panel>

• In .NET MVC, is there an easy way to check if I'm on the home page?

  - by Hairgami_Master

  I need to take a particular action if a user logs in from the home page. In my LogOnModel, I have a hidden field: @Html.Hidden("returnUrl", Request.Url.AbsoluteUri) In my Controller, I need to check if that value is the Home page or not. In the example below, I'm checking to see if the user is on a particular page ("Account/ResetPassword"). Is there a way to check to see if they're on the home page without resorting to regular expressions? [HttpPost] public ActionResult LogOnInt(LogOnModel model) { if (model.returnUrl.Contains("/Account/ResetPassword")) { return Json(new { redirectToUrl = @Url.Action("Index","Home")}); } Any ideas?

• How to check the compatibility between my program and the .net framework versions?

  - by Jack

  Hi all I am writing a program which is targeted to run on .net framework 2.0. I have chosen 2.0 in my VS project. It runs fine on my machine (mine has 2.0 SP2), so there is no compile error. but when I tried to run it on another machine (only with 2.0, no sp), it cannot run. I am aware that I used some method which is supported by 2.0 but only with 2.0 SP2. .net framework 2.0 SP2 seems not being listed in VS IDE, that's why VS cannot give me any warning when I compiled it on my machine. How can I easily check the compatibility of my codes with .net framework 2.0 SP2? or I just have to look at msdn to check every method I have used??? thanks
