i have a fileupload control from which i need the path of a text file. After selecting the file,i need to open the file for reading the data from the text file.For this, i used the following code to open the text file.
fp=File.OpenText(FileUpload2.PostedFile.FileName)
This is working fine in my system.The FileUpload2.PostedFile.FileName statement gives the path of the file.The File.OpenText method opens the selected file.But when i run my project in IIS,it gives the following error:
"File.OpenText is not declared."
The FileUpload2.PostedFile.FileName statement is not retrieving the path, it retrieves only only the filename.what could be the reason?
I have seen 2 methods to handle error in project. One is using try catch in every method and another is using custom page and error log file .I know both method. Which one is the best method?
While understanding the basic concept of inheritance in internet, i came across a piece of code.
I've seen many people using public static void main().Why dont they simply use public void main() ??What's the advantage of using static here ?
Public class BaseClass { Public BaseClass () { Console.WriteLine ("Base Class Constructor executed"); } Public void Write () { Console.WriteLine ("Write method in Base Class executed");
Could not find schema information for the element [URL].NetConfiguration/v2.0:configuration'. and to resolve this i did google again and found a [URL] which is saying to remove that "xmlns" to get error resolved.
I am trying to use a checkbox that is dynamically declared in an .vb file that I am trying to write into my .aspx page. I am able to write a normal checkbox of <input type='checkbox /> from the .vb Class using Response.write, but it comes up blank when using <asp:Checkbox runat='server' />I need to pass whether or not the box is checked back to the server, because I am having to either approve something if one is checked, reject something if the other is checked or do nothing if neither are checked. I have figured out how to make them mutually exclusive either way so that is not the problem.
I have a conditional statement running on my aspx page which looks for a value from a static property (i.e. the object should not need to be declared).

This is the error that is thrown: "BC30451: 'CurrentSession' is not declared. It may be inaccessible due to its protection level."The class is public and to make matters more confusing, it works fine in certain environments but blows up on some.

I am creating an Asp.net web site which will support dynamic data. When I am creating a dynamic web site from Scratch (from template in VS) all is working fine. But when I am trying to add dynamic entity (.edmx) file and running the application I am getting following error

Maybe I'm going crazy or I need some sleep, but I'm trying to use the brilliant membership feature in ASP.NET, and I want to check if the user is currently logged in. The code I got from the book is:
[Code]....
I keep on getting this error: " 'User' is not declared. It may be inaccessible due to its protection level." I noticed it's not even in the code hints that Visual Studio provides. Maybe I need to import a namespace or something, but right now I'm at a loss.
So I have a matser page with a few images that I added using a normal tag <img src="../../Content/logo.jpg" alt="" />. This works fine while debugging on localhost, but the images won't show up when I view the page from the live application. Someone mentioned using URL.Content, but when I added that to my tag I received a "Name URL is not declared" error.
I added the extender and when i tried to add the method this message poped up; Cannot create page method "GetCompletionList" because no Code Behind or codefile was found.
I am using JQuery & JSON (POST) to call webmethod. However I can call only webmethod located at aspx file but not in asmx file Below are sample codes
CustomValidate.asmx Imports System.Web.Services Imports System.Web.Services.Protocols Imports System.ComponentModel Public Class CustomValidate Inherits System.Web.Services.WebService 'ACCESS VIA JSON <System.Web.Services.WebMethod()> _ Public Shared Function AJAX_Test(ByVal date1) As Boolean... Return True End Function End Class Javascript: JQuery JSON function isDates(source, arguments) { var isValidDate; $.ajax({ type: "POST", contentType: "application/json; charset=utf-8", url: "CustomValidate.asmx/AJAX_Test", data: '{date1: "' + arguments.Value + '"}', dataType: "json", async: false, success: function(result) { isValidDate = result; }, error: function(httpRequest, textStatus, errorThrown) { alert("status=" + textStatus + ",error=" + errorThrown); } }); arguments.IsValid = isValidDate; }
It always return javascript undefined error. But if I put the AJAX_Test webmethod in aspx page and replace the url: "CustomValidate.asmx/AJAX_Test" to "mypage.aspx/AJAX_Test". It works fine.
I'm working on converting the TailspinSpyworks shopping cart Joe Stagner wrote in C# to VB using an evaluation version of VS 2010. I have the following public function:
Public Function GetShoppingCartId() As [String] If Session(CartId) Is Nothing Then Session(CartId) = If(System.Web.HttpContext.Current.Request.IsAuthenticated, User.Identity.Name, Guid.NewGuid().ToString()) End If Return Session(CartId).ToString() End Function
For Session in Session(CartId) I'm etting the following error: 'Session' is not declared. It may be inaccessible due to its protection level. For User in User.Identity.Name I'm getting the same error: 'User' is not declared. It may be inaccessible due to its protection level
I have a question about C Sharp ASP.NET:Is there a difference (in code speed, resources) between:public static variable declared in public static class MyGlobals in a 'Code File' template;and the variable declared in a normal 'Class File' template;I use this variable in 2 different Class Files and also in _Default Page codebehind cs file.In fact in my case I need about 20 global variables of type List<string>.
