How To Get A Code Review Of Simple Gallery Method
Jun 29, 2010
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 using the SQLDataReader to execute a Stored Procedure that accepts two parameters (BuildingTID and Department) to return the appropritae Value in my case The Director of the Department. My problem is I get the following error when I run the code that I added below for review. Let me also add that the user is selecting the values that I am using for the stored procedure from 2 DropDownLists. I am getting it when I try to assign the value that is in the Department DropDown
list to the first parameter.
Dim myParm As SqlParameter = getDirectorsCMD.Parameters.Add("@BuildingTID", SqlDbType.Int, 15).Value = (ddlDepartment.SelectedValue)
Also obviously there are more issues with my code than just the error because the datareader records property is false meaning I am not returning a row

Boss comes in and demands that we change an existing dataload process written in .Net 2.0 to call stored procedures on two different servers rather than just one. In his mind (not a programmer) this should be a short overnight process. We have about 60 different SQL Commands that we need to change and test. Is there a simple way to do this that I can't think of? If there isn't we will use something like replication or database mirroring, which is my preference but is likely to get the cold shoulder from my boss, especially since I have never set these up before. A function that takes a SQLCommand as its argument and then iterates through as set of connections to execute the SQLCommand. Change all stored procs to call the same stored proc on a linked server.

how 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 have a web method in my code behind:
[System.Web.Services.WebMethod]
public static string GetStateData(string state)
{
//this is where i want to call a javascript method "GetItems"
}
I have a javascript method that retrieves some values for me and I want to get use one of those values in my web method
function GetItems() {
var variable1= $("#<%=Item1.ClientID %> input:checked");
var variable2= $("#<%=Item2.ClientID %>").val();
return [variable1.text(), variable2.val(), variable2];}
I've searched for ways to call the javascript method from the web method but every time my search results in how to call a web method from javascript.
I did find this but it was done from the code-behind of a silverlight project and when I tried adding the correct reference to my code-behind it wasn't there
var result = HtmlPage.Window.Invoke("GetItems"); Is there a reference I'm missing?

I'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

Is 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;
[Code]....

Is this piece of code where I lock a part of the function correct? Or can it have use drawbacks when multiple sessions ask concurrently for the same Exam? Purpose is that client that first asks for the Exam will assemble it, all next clients will get the cached version.
public Exam GetExamByExamDto(ExamDTO examDto, int languageId)
{
Log.Warn("GetExamByExamDto");
lock (LockString)
{
if (!ContainsExam(examDto.id, languageId))
{
Log.Warn("Assembling ExamDto");
var examAssembler = new ExamAssembler();
var exam = examAssembler.createExam(examDto);
if (AddToCache(exam))
{
_examDictionary.Add(examDto.id + "_" + languageId, exam);
}
Log.Warn("Returning non cached ExamDto");
return exam;
}
}
Log.Warn("Returning cached ExamDto");
return _examDictionary[examDto.id + "_" + languageId];
}
I have a feeling that this isn't the way to do it.

I can place an Excel file in the root directory, use Browse and view an xlsx, xlsm or any other Excel file and it (sometimes) pops up in a browser window with no option to save or do anything other than view the Excel document (you can type in the cells and it gives you the option to save if there are any changes). I'm trying to find out how to do that exact thing client-side.
We have a server that allows a client to upload an Excel file and we want them to be able to review it only. If there is a way to bypass the Open message box that pops, that would be ideal, but just getting it to display in a separate, small browser window would be just what the doctor ordered. The Excel files are varied so the content is always different and not necessarily formatted the same. That removes the ability to go with named ranges and definitions.
Currently with the code we have, users can press a view button to review the file they uploaded for errors but it opens up the full version of Excel and then throws errors because it tries to force a save to a temp file. Not exactly ideal and very confusing to the user. I don't habve the exact code available to me at the moment, but I'm hoping that someone can point me in the right direction.

I'm constructing a new cms with the option to create reviews and articles (blog items). Now if the user wants to write a review he/ she will want to add a lot of images in the text. Now my question to you is , what would be the best option to include those images (with keeping in mind that a CDN can be used later). I was thinking of the following methods:
Break an article in multiple blocks, each block can then include a picture and text. Just add the picture in the text via WYSIWYG editor (easiest option but not so versatile) Upload images separately and include them via tags in article text. Like Title{img_1}Content
