Web Forms :: Profile Object - Compiler Doesn't Recognize Surname?
May 28, 2010
I have created profile objects in my web.config file:
[Code]....
[Code]....
In all tutorials I am finding on the net it says in order to read/write from these properties I just need to use the syntax with C#:
Profile.Surname = "Surname";
But this does not work on my web site code when I'm using C# it underlines and recommends I change to System.Web.Profile.Surname (which I do) but then Intellisense and the compiler do not recognise Surname. What am I doing wrong? I am using Visual Studio 2010 and .Net V4.

I tried this code snippet from ASP. NET 3.5 Unleashed with Visual Studio 2010, I got it built succesfully, but whenever I run it, I got comipler errors:

In VS2008 I create an empty Solution "CmsWork" with a new Web App Project "CmsWork" and add a Web Form "TestForm1.aspx".
From Toolbox I add a TextBox and then in codebehind try to refer to it in Page_Load. Intellisense and compiler both say TextBox1 does not exist in the current context. Tried referencing the control as TestForm1.TextBox1 and CmsWork.TestForm1.TextBox1 --
same error. wtf?
TextBox1 shows up fine in Design View and is labeled "TextBox1". What does Design View know that Code View and the compiler don't? Adding code to call FindControl and typecast to a TextBox works fine, but shouldn't be necessary. Controls can be referenced by ID in a codebehind in a Website project. Why not in a Web App project? This should just trivially work. I must be missing something EXTREMELY simple. I've tried restarting VS2008 normally and with "devenv /resetsettings" -- no effect. Reboot: no effect.
This is VS2008 Development Edition under Windows Server Enterprise SP2, with no VS add-ons, extensions, etc.
Aspx page:[Code]....
Codebehind:[Code]....
Build output:
Error 82 The name 'TextBox1' does not exist in the current context C:Users...DocumentsVisual Studio 2008ProjectsCmsWorkCmsWorkTestForm1.aspx.cs 14 4 CmsWork

In my current project (ASP.Net 2.0) I have a lot of web user controls, among them "Office.ascx". Office.ascx is loaded into another controls using this line:
guide_controls_display_Office o = (guide_controls_display_Office)LoadControl("Office.ascx");
The control I am loading it into has Office.ascx registered using this line:
<%@ Register TagName="office" TagPrefix="uc" Src="Office.ascx" %>
But I get this error upon launching the web page: Unable to cast object of type 'ASP.guide_controls_display_office_ascx' to type 'guide_controls_display_Office'. Why do I get this message? I can see that the first type has "ASP." in front of it. Is that normal?

I had a website with a few asp.net controls with id like:
btnSave and tbAmount
I renamed one of my controls and when I tried to use it in the code behind I get the following error.
Error 5 Name 'tbAmount' is not declared.
I was messing around trying to add new controlls rather than rename, but nothing seems to work.
And now, none of my controlls that were added to the page are recognized in the code behind. They all have the error:
Error 5 Name 'tbAmount' is not declared.
Or
Error 3 Name 'hfNoteId' is either not declared or not in the current
scope. E:NoteTenderNoteTenderMembersManageNote.aspx.vb 33 71 NoteTender
Even my button click event handler gives me the following error:
Error 2 Handles clause requires a WithEvents variable defined in the containing type or one of its base types. E:NoteTenderNoteTenderMembersManageNote.aspx.vb 27 91 NoteTender
I have verified that my inherits is using the correct namespace and class name.

Line 26 is the error I do not understand what or why? At the top of several pages where I use the same code segment several times I declare a new instance of the errorlog class. Now all of a sudden it is reporting it as a Compiler Warning Message it as an error for every instance where I am declaring it.

on a server, I am trying to deploy a website. Originally, the page styles did not work and the some of the .gif and .jpg images didnt show up. I fixed the css problem by adding a http handler mapping through IIS. I tried the same thing to get the images to work but that didn't fix the problem. If the website was fully deployed im pretty sure the images would work so I dont want to change their paths (same with css). The handler mapping i added for css was for "*.css" of type system.web.staticfilehandler. This is the same type i tried for .jpg and .gif. I don't know specifically the purpose of system.web.staticfilehandler because msdn info is very short.

I have created a user control which is inside a folder called Controls and the class is a partial class which inherits from Web.UI.UserControl. Now from my page which is one level up I just try to access the method inside the usercontrol and so trying to cast it as the type of user control. But I get build errors. It just cannot recognize that class. I get Type not defined error. But at times it has recognized the class. Dont know why it does that.

I usually only write in ASP, so I am not very familiar with this script. Can anyone tell me how to how to request a querystring so I can use it to pull the image location. Like this.
PhotoCropper.aspx?userid=1090&picid=47
private const string ORIG_SAMPLE_PHOTO_URL = @"/PhotoCropperC/photos/1090/47.jpg";
I have tried just using Request.QueryString["userid"];, but I get the compiler error. Here is my code:
public partial class PhotoCropper : System.Web.UI.Page
{
//Make sure you give the IUSR_MachineName permissions to the directory below
private const string ORIG_SAMPLE_PHOTO_URL = @"/PhotoCropperC/photos/TheDog.jpg";
//private const string ORIG_SAMPLE_PHOTO_URL = "~/photos/TheDog.jpg";
private const string CROPPED_SAMPLE_PHOTO_URL = @"d:/inetpub/sites/dc/cropper/TheDogCropped.jpg";
protected void Page_Load(object sender, System.EventArgs e)
{
if (!Page.IsPostBack)
{
loadPhoto(ORIG_SAMPLE_PHOTO_URL);
}
else {
loadPhoto(CROPPED_SAMPLE_PHOTO_URL);
btnCrop.Visible = !btnCrop.Visible;

I'm having trouble getting started with the SqlTableProfileProvider. The documentation is here:[URL]I have set up my project exactly like the whitepaper example but I can't access the Profile.SomeProfileField. When I build the project it shows that the Profile object doesn't exist in the current context. I have included the System.Web.Security and System.Web.Profile namespaces. I tried to add a reference to System.Web.Profile but can't find that DLL anywhere to add. Can anyone push me in the right direction?

I receive this error message: LINQ to Entities does not recognize the method 'System.Guid GetUserId()' method, and this method cannot be translated into a store expression. This is my code:
DB.Users user = db.Users.FirstOrDefault(u => u.Id == BOL.GetUserId());
BOL.GetUserId() returns a GUID of the current logged-in user (and this works works).
How can I make this LINQ code line work? Or, what is the shortest alternative? In the mean time I found out that there is a difference between LINQ to SQL and Entities. I use Entities because of the TailspinSpyworks example... but my code is using LINQ to SQL. My current solution is to use a var:
var userId = BOL.GetUserId();
DB.Users user = db.Users.FirstOrDefault(u => u.Id == userId);
Is this a good solution? And, is the execution time of Entities faster than SQL?
