I have been reading up on this all day, and I can't find the answer (or more likely, don't understand the answers I have found) to my problem. I am completely new ASP.NET and trying to make a trasition from Classic ASP.
In classic ASP it was possible to 'pass' variables between include files. In ASP.NET includes are very different. I'll keep this simple:
I have 'header', 'content' and 'footer' pages. The header and footer are both 'includes' in the content page.
I want to be able to pass a variable from the header to the footer. Heres a snip of my code so far:
[Code]....
[Code]....
[Code]....
However this errors crops up in the footer when run:
Compiler Error Message: BC30451: Name 'helloworld' is not declared.
So how do I make this variable available to the pages involved??
I imagine there is more than one way of doing this for many circumstances.
Is it possible to postback to the server, perform a function, and then continue that postback on to an external place? (ie, to a payment system)(the scenario is clicking a button to place an order, mark it as sent, then send them off to the payment page (there are form variables that needs to be sent to the payment screen as well))

We are in the process of refactoring from cf to .net, so, I am working on the Login page and converting it from cf to .net. So, when I am autheticated and enter into our website, I need to redirect it to a cfm page (just temporary, since we will be refactoring that also eventually).
So, I am autheticated (using CustomMembership Provider model for sql server) and then when I redirect to the cfm, the app.cfm should validate the .net session variables. Here is where i am stuck:
I have the .net session variables in the aspx side:something like Session["UserId"].ToString() = Value from a login txt box (also authenticated against data in the database)
Session["UserName"].ToString() = Value from the db corresponding to the User Name entered in the text box.
So, now I have all the session variables in the .net side. Now, how do I retreive these .net session in the cf side? Any small peice of code to retrive the asp.net session variable in the application.cfm side would be great.
I need to declare a variable xyz, then, using a select statement, pass a variable into it so I can then insert it into a table.
Dim @xyz As
Integer
set @xyz = (select xyz
from systable)

2. I get informed that set and let are no longer supported.
3. When I remove the @ I get the squiggly below select.

In my example below I am trying to Bind 2 different size GoogleAds to the 2 first rows in the GridView. One Ad on each row. The ads that are inside.......
(i2 == 0) and(i2 == 1).
I need to use <%if (Counts < 2) %> in HTML to restrict it to just 2 Rows, so this variable needs to be passed correctly also. As it is now, Counts is not passed correctly so <%if (Counts < 5) %> needs to be set in order to see any ads at all. I beleive this is because Page.DataBind() is binding the last ad in memory from the loop.
So when running this code, the same ad (i2== 2) is set to 3 rows in the GridView. This is my problem!

I have gotten alot of help lately on my project and think I only have one more issue that I can't think of how to do. What i'd like to do is pass a login name and password from a Login.asp page to all of my other pages. So for instance if I have a successful login, I am taken to the Home.asp page. But i'm not sure how I can pass the LoginID used from Login.asp to the Home page. Ideally i'd like to use this information in the SQL connection strings, and to customize the Home page to show orders assigned to certain people that are logged in.

View 10 RepliesI'm trying to convert a game I made (WindowsFormApplication) to an ASP.NET page.
My Problem is that I have a lot "private" variables in my WindowFormApplication and those variables are important for the game. But when after I Declare all my variables (in my Page_Load), they turn null no matter what I do(click a button, refresh the page).
Is there anyway to save my variables between buttons (other than Session, because I'd have to create like 6 more sessions)
I define this variables as following in every page in project:
Code:
SqlConnection cnn;
SqlCommand cmd;
SqlDataReader reader;
cnn = new SqlConnection(ConfigurationManager.ConnectionStrings["myconnection"].ConnectionString);
I lookup on way to facilitate this process i would define this variables one time in project.
On my current project I need to pass a variable from a page to another one.I do not have particular problems with that part of the code but my question is more orientated towards the practicality. I want to make sure everything is fine and the user redirect to a "default" page with an error message if it fails.
Page 1 asks the user for some information, on submit the data is stored in the DB and the Index of the row inserted is passed to a second page using a Session variable. What I'd like to do is check the variable on Page 2 and make sure it is fine. If the Id is missing or incorrect I would like to redirect to the error page. But what is the best way of doing so?
At the moment I have this code on the Page_Load of Page2: [Code]....
In the error page I display an error message if the Session["ERROR_MSG"] is set. I basically need to know if this is the right way of doing this kind of check. Is it OK to put it in the Page_Load? Should I use Page_Init?

$.ajax({ [code]....
But I am getting compiler error when use Page.Master: Reference to non-shared member requires an object reference
How to pass Master Page object or Page to Page method?. So I can use in Sared method.Is there any way I can access Textbox value directly in Page method? I need access couple of controls in Page Method.
