I'm having some troubles using Session Variables as they are being used as Reference and I want to use them as value.
I got to this debuging my solution and I created something like:
DataTable dt =
(DataTable)HttpContext.Current.Session[
"SearchReturn-DataTableSchema"];
// Adding Rows of Data to DataTable dt
HttpContext.Current.Session["SearchReturn-DataTable"] = dt;

From what I understand, the id of the master on an ASP.NET page is "aspnetForm". I noticed today that for some reason in one of our pages it's now "form1". What would cause this change? Where should I look for the root cause of this naming change? We've got a lot of JavaScript variables that (sign) reference "aspnetForm" that are now broken.
View 1 Repliesi am trying to collect 2 variables from one hyperlink, and use those variables in the page_load to set as session. but i don't know how to collect those 2 variables
such :
<a href="javascript:;" onclick="wsChangeColor('mainData', '#FF0000','#FFE4E1');return false;" title="Change color" id="red">1</a>
i would like to collect '#FF0000','#FFE4E1' or direct set '#FF0000','#FFE4E1' to string then send to pageload, how can i do this by only clicking on it ?
I have this code in javascript: var x = e.mapX; It gets the X-coordinate of a map. What I want to do is that I want to store this into a c# variable. I have a class named Test with an integer property X. I want to store var x into X. In the codebehind, I have this on the Page_Load: Test test = new Test(); Then I am trying this on the javascript code: var x = e.mapX;
View 16 Replieswhats the exact use of static variables in overall programming in .net and for asp.net...
Recently i went for the interview where interviewer asked me 2 question which i was not sure for the same..
whats the use of session object, i said sessions are the server side object, they are used when you want to store user specific data at server side, then he asked what if i want to use static variables for the same, i was mum, can anyone tell me how asp.net will behave if i store the user specific information in static variables.If i use cookies which are the best option to store the data at client side (not sensitive one), but what if user has disabled cookies on his machine, will my application would crash.
I am trying to call web reference "A" in an application.
The web reference "A" will then call a function in another web reference "B" through HTTPS connection (require certificate).
Then I keep getting the following error:
An unhandled exception of type 'System.Web.Services.Protocols.SoapException' occurred in System.Web.Services.dll
When you use ASP.NET web site (instead of web application model) and add reference to an assembly from local folder, Visual Studio, it seems, understands that this local assembly is also in GAC and so does NOT copy this assembly to bin folder (as it does with non-GAC assemblies), but simply adds new record in web.config file.
Why such a behaviour? Is it possible to force copy to bin folder (I need this since .dll is not on target environment)? I can add assembly to bin folder as file and it will work, but in this case bin folder contents will be in source control, which is not good.
I am working on converting a project from C# to VB and am facing this weird issue. 1 page cannot compile and I get the reference error, but the weird thing is that the compiler shows the error as coming from ASP.NET generated code. Visual Studio shows me that error is coming from my ASPX page. I cannot seem to figure out why or where this error is occuring. Also if I take the inherits attribute out I don't get the compilation error. The code in aspx page is below:

I am using VS2005, and a newbie at table adapters, DAL & BLL. I have a single dataset (in DAL) and 2 classes (in BLL) named Class1.vb and Class2.vb.
When I try to call a function from Class1 within Class2 I get the error "Reference to a non-shared member requires an object reference".
Here is a sketch of my code structure:
[Code]....
I have a Web service which, when updated on one computer with VS2008 works perfectly fine, but on another computer does not. The critical difference is the contents of the auto-generated Reference.cs.
In the correctly functioning environment, the methods have fully qualified class names, refering to classes in a class library. However, in the problem environment, the class names are unqualified and partial classes are declared near the end of the file. E.g.
[code]....
The code is under source control. Checking out to the working environment works straight away, checking out to the problem environment will only work if the reference.cs is manually edited to be like the working environments. Transferring the project manually from problem environment to the working one only requires an "Update Web Reference" to be performed to allow compilation. Both Reference.cs files claim to be auto-generated by the same tool version. The settings from the good environment have been exported to the other. No success so far...
I have a url like this:
http://www.somepage.com/main.aspx. In this page, when I click on a link it takes me to a page
http://www.somepage.com/cental.aspx?cid=200. So in the cental.aspx.cs page I did the following in the page load:
if(request.querystring["comp"].tostring() != null)
{
//do some thing [code].....
So I got an error like: object reference not set to an instance of reference.My problem is, I am using the same page. So when I go from some page, I will have "comp". but other times not. So when there is no "comp", how do I handle it in request.querystring?
I do not receive this error when I open my website application in vs 2005. When I open in vs 2008, I get this error. What gives?

Businesslogic area is imported into each of 3 pages with this line.
in my default.aspx page i have a dropdown List and a textbox with a submit button below that there are 2 listbox... and the dropdown list holds the names of the listbox
my logic here is to select an item from the dropdown list and put some text in the text box and submit the form which will add an item to the listbox selected.. but when i do this i get an error saying Object reference not set to an instance of an object. i tried to figure out the problem and found that when i remove the reference to the Site Master Page it works fine and when i undo and apply my reference back to the Site Master Page i get the same error.

Using VS2008, I noticed that in Class Project I only have a choice of adding "service reference" where as in Web Application project, I have two choices "web reference" and "service reference".
I have used web reference. How is "service reference" different from web ref? and what's the major purpose of service ref?
I am using grid view as mentioned below, it is giving me error "object reference not set", but if comment allowpaging and pagesize lines, it works. let me know whats wrong I am doing?

I'm helping out a colleague on this one so if I'm missing some details that's why.We have an asp.net 3.5 web application calling a WCF service. Originally the app used a "Web Reference" to register the service however after having some trouble and burning an incident with Microsoft their solution was to replace the "Web Reference" with a "Service Reference" to the WCF service.This is great except the problem is that when we create a Service Reference, the method signatures are different than they were when a Web Reference was used.From what I've read this may be expected, however in our case this would mean some significant changes to the application and of course it was due yesterday...so......I'm wondering two things:Is it normal/expected that method signatures will change based on the reference type?Is there a way to create the Service Reference that will generate method signatures identical to the original Web Reference?
View 1 RepliesI cant figure out how to use the Application["myvar"] variable to store data for the application in asp.net 4.0 web app using c#. It say Application is not a known object and I can't for the life of me figure what to do a "using" on to expose it. I am in a static class at the time I cant use it. It seems to work in other units?
View 3 RepliesI have this function that I want to pass the IP and port to and check for a connection. It works fine if I put "127.0.0.1" in the tcpClnt.Connect line. But if I pass the IP2 as shown in the line commented out, it tells me No such host is found. It's like it thinks "IP2" is the host name. How can I pass a variable in there?

Aif i have a choice between static veriable and session for just storing an integer which one of these should i prefer??
I have some WCF services. These services run in ASP.NET. I want these services to be able to access a static variable. My problem is, I'm not sure where the appropriate server level storage mechanism is. I don't want to use the database because of speed. But, I want the static variables to stay in memory as long as possible. In fact, I'd like it to stay until I restart my server if it all possible.
View 2 RepliesI'm using ASP.NET MVC (I'm really new to both asp.net and the asp.net mvc type projects, but trying hard to learn).
I've set up MVC with a controller so that it runs a C#.net method which;
queries an mssql db
converts it to json
returns the json string
It's called from the javascript by requesting an url with a parameter. But what I need now is for the C# part to read two integer variables from the javascript. What would be the best way to do that, and does anyone have any good examples/code that I could look at?

I have this VB ASP.NET sql data source that calls a stored procedure.
I also on the same page have a custom html form.
What I need to do is asign the form values the values of the database entries.
So something like:
UsernameFormField.Value = DatabaseParameter "username".ToString
why I couldn't get the variable from the URL.
<meta property="og:title" content="<% Response.Write(Request.QueryString["title"]); %>"/>
For some reason the code, <% Response.Write(Request.QueryString["title"]); %>, does not retrieve the data in this case. It works fine if I put it in the title tag though.
This question actually refers to a classic ASP page I'm working on, but I'm assuming that app variables work the same in both ASP and ASP.NET Let's say we have a bunch of websites, owned by different people. The sites are all different, but the common theme is they are car enthusiast websites. Each of these websites has their own unique index page (of course), but also "common" pages, which are pages shared by all the websites.
One of the common pages, checks for the value of an application variable, which may or may not exist. For example, lets call this page luxurycars.asp, which is a simple page that shows the top 10 luxury cars of this year. This common luxury car page will pull and use the app variable like so:
[CODE]
Dim SiteOwner
SiteOwner = Application("OwnerName")
Response.Write("This site is managed by " & SiteOwner)
[/CODE]
This app variable is set uniquely in each clients index.asp page like so:
[CODE]
Application("OwnerName") = "John Doe"
[/CODE]
Will this work? I just started learning classic ASP (for my job), and I'm reading that application variables are universal and only one copy of the variable will exist. So does this mean if John Doe sets Application("OwnerName") to "John Doe" in HIS index.asp page, will everyone that visits the common luxury car page see John Doe's name? Regardless of whether they got to that page via John Doe's page or someone elses? And if so would using a Session variable instead solve this problem? Sorry if this sounds confusing, let me know if I need to re-word it or give more detail...
