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.
This is my page code
Code:
Protected Sub btnLogin_Click(sender As Object, e As EventArgs) Handles btnLogin.Click
Dim blnLogin As Boolean
blnLogin = Login(txtUserLogin.Text, txtPassword.Text)
If blnLogin = True Then
[Code] .....
So after the user presses the Login button there should be 3 variables stored in a session, this works (checked using trace='true')
Session State
Session KeyTypeValue
LoggedInSystem.String
LoggedInUserSystem.StringUser
LoggedInIDSystem.Int322
That's fine. Now I click on the AddToWall button to check if I can get the LoggedInID, it shows an empty messagebox.
In the trace there are no Sessions keys left.How can I make it keep the keys after postback/after clicking on buttons?
Note: When calling GetFriends(Session("LoggedInUser")) in the same sub as the Login button the variable does get passed to the class with sub GetFriends()
Here's my web.config
Code:
<?xml version="1.0"?>
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0" />
<sessionState timeout="30" />
</system.web>
</configuration>
I have a function that sets the Theme for the page but I want to define this in a MasterPage for each page that uses that MasterPage. This seems like the most likely way to do this to me, am I doing something wrong?
Here is what I have:
[Code]....
If i copy this to an ASPX page it works but it doesn't seem to work at all in a MasterPage.
I have a page which is linked with masterpage.
In my masterpage i have already defined metakeywords and description. But for one of my page i would like to define metakeywords and description which will be for that page only.
The metakeywords and desciption defined in master page is for the website.
Where and How to define metakeywords and desciption for any page which doesn't have <head> tag as it is linked with masterpage.
This is my About.aspx page code :
<%@ Page Language="C#" MasterPageFile="~/MasterPages/OneColumn.master" AutoEventWireup="true"
Inherits="Web.AboutPage" CodeBehind="About.aspx.cs"
%>
<%@ Register TagPrefix="MyTag" TagName="Topic" Src="~/Modules/Topic.ascx" %>
<asp:Content ID="Content1" ContentPlaceHolderID="cph1" runat="Server">
<nopCommerce:Topic ID="topicAbout" runat="server" TopicName="About">
</nopCommerce:Topic>
</asp:Content>
I have to define a global and unchangeable variable in a web page. I used static variable but its content is the same for all users that use the page and it is bad. I dont want use Session variable.

My Project is a normal web site, not a Web Project, and I am using VS 2005.
I am trying to define common Master Page Type in app_code which has an area to display error messages and the like. Very simple.
I added the following in app_code:
[Code]....
Also, I added the following in Master Page Source Declaration:
[Code]....
Also, I added the controls tblrowErrMsg and lblErrMsg as server controls to the Master Page.
Why I am doing this ?
This will allow me to display error messages from nearly any where inside the code in code-behined, app_code, and other core Class Projects (DLL).
I have designded a asp.net server control that have an embeded javascript file.
document.getElementById("div_Messages_Back").style.left = 0;
document.getElementById("div_Messages_Back").style.top = 0;
document.getElementById("div_Messages_Back").style.width = document.documentElement.clientWidth;
document.getElementById("div_Messages_Back").style.height = document.documentElement.clientHeight;
document.getElementById("tbl_Messages").style.left = (document.documentElement.clientWidth - 250) / 2;
document.getElementById("tbl_Messages").style.top = (document.documentElement.clientHeight - 120) / 2;
function btn_Close() {
document.getElementById("div_Messages_Back").style.visibility = "collapse";
document.getElementById("tbl_Messages").style.visibility = "collapse";
}
I want the first 6 line of my javascript file run at runtime. But I recieve error at runtime:
Error: Object Required.
I need to access a variable that is declared in a master page to a child page. I'm using asp.net 2.0 (vb). I'm sure this should be easy and is down to my inexperience with asp.net! A rough guide to my code is below;
MASTER PAGE
<%@ Master Language="VB" CodeFile="MasterPage.master.vb" Inherits="MasterPage" %>
<script runat="server">
Public UserNumber As Integer = 3
End Sub
</script>
CHILD PAGE
<%@ Master Language="VB" CodeFile="MasterPage.master.vb" Inherits="MasterPage" %>

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)
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?

I am developing an application using Visual Studio 2010 and SQLServer 2008. My application has two pages and the first page contains a GridView with all the records "User Administration" and when user click on any Username (template field ->linkbutton) I read the USERID like this.
Session["UserID"] = e.commandArgument;
Response.Redirect("UserOperations.aspx");
which takes it to the Data Entry page where user updates the information and save the data.
The problem i am facing is that when I hit the browser REFRESH button couple of times the session variables looses the value which is trouble for me as I am using Session Variables for different purposes.
I know there are at least 2 ways to send Variables to another ASPX page.
The first way is the use <form> and <input type="hidden">
The second way is the put the variable(s) in the URL such as http://www.joesmith.com/Sample.aspx?var1=bob&var2=cunningham
Is there a 3rd way to send variables using VBScript inside the <script runat="server"> tag?
is it possible to access public page variables from ListView.EmptyDataTemplate ?
View 1 RepliesI have an app which has a form that used to use AutoPostBack rigged controls (dropdowns, radiobuttons etc.) in an updatepanel, and I used to set session values on each postback. I posted the form using PostBackUrl to an external page, using a bit of javascript OnClientClick to copy my data into meaningfully named hidden fields.
Now, I've had to rewrite the AutoPostBack-ing controls so that all the cascading dropdown work and date calculation etc. is done in JavaScript, and not in C# - no more postbacks, no more updatepanel.
This means I've lost the ability to set my session values on postback. Can anyone think of a solution for setting these before I post my form? I need to set the session variables, plus post (querystrings are not an option) to the external page with the values from my form - and actually send the user to the external page, too.
