I'm new to ASP.NET, and I'm trying to get started with a simple tutorial. But I'm having problems configuring the ability to actually display a .asp or .aspx file on my computer. I have .NET 4 on the computer I'm attempting the following code:

View 1 Replieshow to code a simple calculator in ASP.NET? Everything I try isn't working...Here's what I need to do:
Create a web page with a simple calculator. The web page will have two text boxes (with labels) for data entry, radio list box to select the operation (+, -, *, and /), label to display the result, a calculate button and clear button. Use Validation controls to validate the data entry. Write the code using try/catch block to catch any data entry error. If there is any data entry error then display the message in the result label. Create an appropriate header for the web page and add graphics to make the page look professional. Set the default focus of the form to the first text box and default button to calculate button.
I want to SELECT a user from a table using the WHERE clause. I know how to write the query, but how do I execute it and how do I match the UserId with the current one (how do I know what the current userid is using the login controls)? I basically want to display profile information by selecting the table and matching it to the userid.
View 2 RepliesI'm going thru an asp.net 4 book, and I'm at a part about classes and their properties and functions. But up to now, all the examples involve a web_site, with controls, code_behind files, CSS, etc. But, I get to places where I don't understand the examples, so I look out on the web for other resources. For example, I found the code below to demonstrate the "ToString" function. My problem is, I'm not sure know how to test a little piece of code like this. Can't I just open up an application or project or something, paste this in and run it?
Module Module1
Class Perl
Dim _a As Integer
Dim _b As Integer
Public Sub New(ByVal a As Integer, ByVal b As Integer)
_a = a
_b = b
End Sub
Public Overrides Function ToString() As String
Return String.Format("[{0}, {1}]", _a, _b)
End Function
End Class
Sub Main()
Dim p As Perl = New Perl(2, 3)
Console.WriteLine(p)
End Sub
End Module
I wanted to get a code review of my methods for creating a simple list/gallery display in ASP.NET. I am looking for specific ideas on how I might approach this same task differently. My goals are simplicity, rapid development, and ease-of-use.
The task: Create a simple image list view (gallery) for a folder in ASP.NET web forms.
How I Did It: I created the image controls on the fly and add them to a placeholder template. I added line breaks using literals controls too. Finally, I add a query string to the page for the "paging".
What other ways would one recommend to do this? I had considered to use a grid or listview. My goal was to do this really quickly.
I am new to the Web Services. I am learning this one. I am 10th stander. I need a simple code and procedure how to use it in our web site?
View 2 RepliesIs there any documentation or tutorials anywhere on what can be done or put between these magical symbols in ASP.NET aspx files? I've tried a number of resources though they all seem aimed at Classic ASP.I'm already writing protected functions for updating and grouping in my grids using Eval. But, for example, I noticed the following in my code :-
ConnectionString="<%$ ConnectionStrings:WORK_MyConnectionString %>"
I presume that $ ConnectionStrings is a macro or built-in function of some sort and I'm trying to track down what else is available in this area. I would also like to use the
<% if (my function) then .....endif %>
to conditionally write items to the page.
I need to pass a value from the selected button in user control to the containing page. I have it working fine but only by using a bunch of if statements that strike me as ugly. Can't figure out how to use a switch statement which, I think, would be a bit less cumbersome. I'd welcome on how to clean up this code (obviously I'm new to delegates).
Here's the code:
User Control:
<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="DelegateUserControl.ascx.cs"
Inherits="Foobar.UserControls.DelegateUserControl" %>
<asp:Button ID="Button1" runat="server" Text="Button 1" onclick="Button_Click" />
<asp:Button ID="Button2" runat="server" Text="Button 2" onclick="Button_Click" />
<asp:Button ID="Button3" runat="server" Text="Button 3" onclick="Button_Click" />
User Control code behind:
using System;
namespace Foobar.UserControls
{
public delegate void SendButtonValueToPage(int buttonValue);
public partial class DelegateUserControl : System.Web.UI.UserControl
{
public static event SendButtonValueToPage SendButtonIdToPage;

Here is my situation. I have inherited an MVC 2 application. I am learning MVC 2 on the fly with this application. I am trying to validate a checkbox by doing this: Grey out the submit button until the user clicks on the "checkbox" then the submit button is enabled. 1st question: Where do I place the code to make this happen? 2nd Question: How do I go about doing what I explained? I wanted to use a simple javascript code within the click event of the checkbox but I don't see this in MVC 2.

View 1 RepliesI'm using CRv9 and want to make use of Google Charts API for generating QR code on fly (in asp .net) and display it in the Crystal Report in a PDF format.I have spent the whole day looking for solution with no luck. The way we output the report is we use .rpt file, feed it with data and use Response.OutputStream to feed to browser. No CrystalReportViewer control hence CSS solution is not an option.
Now, I got as far as added an OLE Object from file with Link, which I would be overwriting every time the new QR code is generated. I apreciate that CR requires it to be a bitmap, so I was planning to download and convert the google's generated PNG file to BMP, that's not an issue. The problem is that Image in the report does not update after I replace the file. Meaning, it displays the original image, which was added as an OLE Object.
If I open this report in CR designer, the image gets refresh/updated and I'd have to save changes to the report to see this new image next time I generate a PDF file.The question is really how to achieve a dynamic image in Crystal Reports 9? Remember, Picture object did not have a Graphic Location property until vXI, so I cannot use that.
Manipulations with DataSets is not an option either as we're not giving report a datasource, instead we just map the fields with FormulaFieldDefinitions.

I have an aspx page which retrieves messages from a database. One message is an instruction to the user to copy some xml from a file. I'm trying to tell the user that they need to copy the code lying between "<?xml" and "</reports>".
The problem is that when the message is displayed to the user the line containing the quoted code is missing. It appears that the page is taking "<?xml" and "</reports>" as instructions to the page and trying to action the tags. I just want to display these characters on the my page. how I can get these code snippets to display?
I upload my pages I create as .aspx on my web host [URL], but the files display in code. For an example: [URL]
View 4 RepliesI wonder how it would be possible to launch a series of popups, containing a form,
from code-behind.
I possess a list of objects 'Products'
and I wish I could change one property (quantity) of each "product".
Here's how I build my list (normally I use a database).
Private List<Product> listProduct;
listProduits = new List<Product>();
Product objProduit_1 = new Produit;
objProduct_1.ref = "001";
objProduct_1.article = "G900";
objProduct_1.quantity = 30;
listProducts.Add(objProduct_1);
ProductobjProduit_2 = new Product;
objProduct_2.ref = "002";
objProduct_2.article = "G900";
objProduct_2.quantity = 35;
listProduits.Add(objProduct_2);
And I would like displayed popup one after one.
Is there any way to display a Calendar Extender popup without using it the traditional way? and the also grabbing the value selected?
Some code that I made up to make it more clear:
<table>
<tr>
<td><input type="text"/></td>
<td><input type="text"/></td>
<td><input type="text"/></td>
<td><input type="text"></td>
</tr>
</table>
$('table :text').focus(function(){
displayTheCalendar();
});
//PSEUDOCODE!!!
function onDateSelected(e){
$(this || event.srcElement || etc..).val(e.dateSelected);
}
I guess I need some kind of 'hack' here for the js of that Calendar.
PS: I must use the extender or any control that looks and feel like the extender.
is there a way you can make the results of vb code held on an aspx.vb page display within a contentplaceholder on a master page? I've included my code below, there is a textbox and 2 buttons on the aspx page but the code runs in the aspx.vb page. The code basically works, but when run it prints the resulting table above the placeholder rather than within.
