I've done a search and read a few things, All i'm trying to do is set a variable in the code file and call it in the page file asp.net vb.net 3.5. I've tried like this in the code file:
[Code]....
And in the design part of the page:
[Code]....
But it says that name isn't declaired. What am I doing wrong?
I am using some code I found that generates a random password. I am in the habit of putting code in a seperate file. The code was written in the same file and I'm trying to move it to a seperate file and get the following message. Also, below, I posted
the original code (code on same page as aspx) and what I did (code in seperate file).what adjustment needs to be made to make the seperate code file work?
Compiler Error Message: BC31143: Method 'Public Function GeneratePassword(length As Integer, numberOfNonAlphanumericCharacters As Integer) As String' does not have a ignature compatible with delegate 'Delegate Sub EventHandler(sender As Object, e As System.EventArgs)'.

I'm missing a the code browser when I create pages that have the code not placed in a seperate file. For pages with .asp.vb files I get the browser correctly.
I think it's called a code browser but just in case it's not I mean the dropdown that shows Page Events, Buttons and other controls that can be selected along with their events.
How do I turn on those dropdowns for pages with code behind that uses <script> tags in the actual .aspx page?

I have a separate aspx Page called Home.aspx page and a separate class called class1.cs

The project I'm working on allows an end-user to modify CSS code to integrate the application as best possible. Most of the CSS values are stored in a database and need to be retrieved and parsed dynamically. I setup a Style controller, and gave each stylesheet an action, and then passed the configuration data through to the View. I set the ContentType to "text/css" and then generated the stylesheets. This works fine, but the problem I'm running into is this: none of the code works in the application. I include it in the head code, but it doesn't parse in the code. An example of what I do is this:
<%@ Page Language="C#" Inherits="System.Web.Mvc.ViewPage<dynamic>" ContentType="text/css" %>
.element {
background-color: <%= ViewData.Model.BackgroundColor %>;
}
I include it like so:
<link href="/style/Basic" rel="stylesheet" type="text/css" media="all" />
When I include the CSS code in a partial view and include it using the ViewModel (wrapped in style tags) in an action, then everything works fine. It is when I try to parse this as a separate file when it does not work. Is there something I am doing incorrectly? Or is there some kind of glitch?

This question has probably been answered before, when adding a new web form, I do not see an option that allows you to place code in a seperate file for a project (it does it automatically). But for websites, I see the option. Am I missing some option?

View 7 RepliesI have a JavaScript-based timeline which needs to use data from an SQL server. The queries and the JSON conversions have been worked out in the form of C#.NET functions within a code file related to an .aspx page. So for a complete newbie to ASP.NET, how do you set up a function call like this from JavaScript?I would love it if someone had some simple example code I could learn/get some pointers from.Edit: I am using .NET 3.5

I was trying to stay away from using SSIS package, and with help from another member, i was able to get the process to work with an excel spreadsheet.
But part of my project requires us to allow .csv files.. so my question is how can i modify the code i have now for the excel to work with a .csv file?
You can find the current code in my original post here:
[URL]
I not sure what the best solution is for the end result.. I was reading somewhere online that you can right the data from the file to a datalist or gridview so you can present the user with a view of what is being uploaded, then use that datacontrol to insert into SQL.
In my current code, im uploading the file, then using that file to do the insert. This works fine for .xls files.. but i need to accomplish the same thing for a .csv file.
I am having one doubt regarding the use of static variable in Asp.net pages.I am having one page say UserDetails.aspx.In this page, I have one static variable to store some data specific to a user. So, will this ?

I did the following:
(1) File / New / Web Site
(2) Right-clicked on new website name

(5) Didn't see any check boxes for selecting either "Place code in separate file", or "Select master page".
The checkboxes are missing. Is this a configuration problem?
I am using asp.net 2005 with vb and developing MCQ program.
I am reading question information from a database and array . the array is "public shared" one. the problem is when two users are login to the system both are getting the same array.
my reqrement is give seperate instances for the diffrent users.
as an example the first user can open paper with 25 questions and second user can open paper with 10 questions. First it display no of questions as 25 and when then second user open the site, then the first site also display the total no of question as 10.
I tried to use variable declareing with DIM statement then they are unable to access from other events.
I'm trying to do: I have a webform with a datalist. The datalist shows projects (projectname, image and an imagebutton). When a visitor clicks the imagebutton two events should take place:
- First: data should be send to SQLdatabase (projectID, name of project, sessionID, datetime etc).
- Second: a pop up window must be opened to an existing webpage of the facilitator of the project, using an url which (is in my database).
The problem is my two seperate pieces of code-behind work fine, it's just that they won't work together. Here is my code: The imagebutton:
< asp:ImageButton ID="openButton" CssClass="openbutton" runat="server" ImageUrl="~/Images/openButton.png" CommandName="Sendto" CommandArgument='<%#Eval("ProjectID")%>' OnDataBinding="openButton_DataBinding" ></asp:ImageButton>
Code behind send to database:
protected void list_ItemCommand(object sender, DataListCommandEventArgs e)
{
if (e.CommandName.ToString() == "Sendto")
{
string projectId = e.CommandArgument.ToString();
bool succes = ProjectAccess.Projectopen(projectId);
}

I often want to call a function in the code behind using the "<%# ... %>" syntax. Sometimes is works and sometimes it doesn't. It is also a difficult syntax to search for. Can someone point me at an explanation of the working (or not) of this syntax?
I just tried this:
<asp:TextBox
ID="TextBox1"
runat="server"
Text="<%# getBCSConnectionString() %>"
></asp:TextBox>
For example. The function is in the code behind (it returns a string). The TextBox is empty and no break point is hit in the function; it does not appear to be called.

Here is what I am doing.
I have a web form where a person will edit their blog article. At some point, once they are done editing, they can click a button "Publish Blog Now".
Once the blog is published in the click event on the server side I am doing a query to get a list of subscriber email address.
These are people who subscribed to this blogger and wish to receive an email notification whenever this person publishes a new blog.
What I just realized today is that my hosting provider only allows me to send a maximum of 200 emails per hour. Which means in my loop I need to sleep for roughly 20 seconds between each email notification sent. But I dont want the user who clicked the publish button to have to sit there and wait while that process is going.
How can I return to the user but yet continue to run some code on the server side to send out the emails in the background even if user closes web browser?
