European Visual Studio 2017 Hosting - HostForLIFE.eu :: Working With Progress Bar Control In Visual Studio 2017

clock July 18, 2018 11:12 by author Peter

In this article, I will explain how to use Progress Bar control in Windows.Forms applications. Progress Bar control is an important control; many applications need to include progress bar control in them. Designing a Progress Bar in Windows.Forms application is simple and it can be used in the application. Follow the steps given below to create a Progress Bar.

Step 1
Open Visual Studio 2017--->NewProject--->Windows.Forms application and name it Progress Bar.

 

Step 2
From the toolbox, drag and drop the button control into the form and right click on the button. Select property. Here, you can change the text, font, and the name of the button. In my Project, I changed the text of the button to "Load Progress Bar".

Step 3
Now, drag and drop the Progress Bar from the Toolbox to Windows.Forms in Visual Studio. Right-click on the progress bar and select property. Here also, you can change the text, font, and name of the Progress Bar. Progress bar is a control that applications use to indicate the progress of a lengthy operation, such as calculating the result, downloading a large file from the web etc. Progress Bar control is used whenever an operation takes more than a short period of time. The maximum and minimum properties define the range of values to represent the progress of a task.

Step 4
Now, drag and drop the timer control from the toolbox to the Windows.Forms in Visual Studio. The detailed function of Timer control is already explained in my previous article.

Step 5
Now, it's time to code. Follow the code given below in the screenshot for the Button-Click event.

Step 6
Now, follow the code given below in the screenshot for the timer click event. A progress bar control is used to display the progress of some activity. I have added a timer control to the form and on the timer tick event handler, I increment the value of the progress bar.

Output
Compile and run the project. The final output of the project obtained is as given below in the screenshot. As the "Load Progress bar" button is pressed, the progress bar starts to display the progress.

Summary
Hope you all understand the working of a progress bar. In case of any problem or error, please feel free to comment down below. In my next article, I will explain how to install NuGet Packages and work with Circular progress bar control in Windows.Forms application.

clock August 10, 2016 20:56 by author Peter

In this tutorial, i will tell you about how to Remove White Line Or Space In Visual Studio.  I know this a not a new concept but i seen many times in my office guys lots of time spent remove the white space or lines. I know that this type of code snippet but this code snippet is very useful for everyone experienced or fresher developer. when we make a function or develop code am sure some extra lines add in code. Like this way,


             button2.Text = "Please Select Me..."; 
         } 
  //Blank Line
  //Blank Line
         }; 
 
     } /// End button2 scope here.  
 
  //Blank line
// Blank line
 
     private void Save_Click(object sender, EventArgs e) 
     { 


suppose this type of blank lines on every pages. if you want manage your code that's no possible remove line one by one. Thank to Microsoft to give to option remove all blank line.

Open the find and replace pop up windows and past the code "^(?([^\r\n])\s)*\r?$\r?\n" in find textbox.

ASP.NET MVC 5 Hosting - HostForLIFE.eu :: How To Create Dropdown Menu?

clock May 4, 2016 00:37 by author Anthony

In this article, I will explain about how to implement Dropdown list in ASP.NET MVC. In traditional ASP.NET it is very easy to implement just by drag and dropping where we want. But in MVC we need some attention to create Drop Downlist.We have Dropdown list Html helper in ASP.NET MVC but we need to know how to bind data to Dropdown list Html helpers.
we can implement Drop down list in ASP.NET MVC in 2 ways.


Free ASP.NET Hosting - Europe

1.Using normal HTML Controls(select tag):

We can implement  dropdownlist using HTML <select/> tag like below
 ExampleCode:


<select id="html_dropdown">
    <option>--Select--</option>
    <option>India</option>
    <option>US</option>
    <option>China</option>
    <option>Russia</option>
    <option>United Kingdom</option>
</select>


2.Using HTML helpers:

Method 1: 


It is very easy to implement dropdownlist using normal html tags. But, if you want to bind data dynamically to the HTML tags it becomes complicated.To overcome and to make it easy to bind data to Html controls Microsoft introduced HTML helpers Methods.Here we are using Dropdown HTML helper to bind object data to Dropdownlist
.


Advantages:
1.It is also easy to implement.
2.Dynamic binding of data is very easy
3.We can easily implement cascading dropdownlists
Note:In method 1 i am sending data from controller using ViewBag. 


ExampleCode:

//Using ViewBag
            List<selectlistitem> item = new List<selectlistitem>();
            item.Add(new SelectListItem { Text = "India", Value = "1" });
            item.Add(new SelectListItem { Text = "China", Value = "2" });
            item.Add(new SelectListItem { Text = "United Sates", Value = "3" });
            item.Add(new SelectListItem { Text = "Srilanka", Value = "4" });
            item.Add(new SelectListItem { Text = "Germany", Value = "5" });
            ViewBag.html_helper_dropdown = item;
</selectlistitem></selectlistitem>

View code:

@using (Html.BeginForm())
{
    @Html.DropDownList("html_helper_dropdown","--select--")
}


Method 2:


In this i am sending data using ViewData to Controller with the same data source


Code:

List<selectlistitem> item = new List<selectlistitem>();
 item.Add(new SelectListItem { Text = "India", Value = "1" });
 item.Add(new SelectListItem { Text = "China", Value = "2" });
 item.Add(new SelectListItem { Text = "United Sates", Value = "3" });
 item.Add(new SelectListItem { Text = "Srilanka", Value = "4" });
 item.Add(new SelectListItem { Text = "Germany", Value = "5" });
ViewData["viewdata_ddl"] = item;
</selectlistitem></selectlistitem>

view code:

<p>Using View data</p>
@using (Html.BeginForm())
{
    @Html.DropDownList("viewbag_dropdown",ViewData["viewdata_ddl"] as List<SelectListItem>, "--select--")
}


Method 3:


Model binding.In this method we are binding the data using Model.This method mainly used for Strongly typed Views.


1.First create a model class with the 2 properties. one for Dropdown values and another for storing the selected value.


Model.cs:

using System.Collections.Generic;
using System.Web.Mvc;
 
namespace Dropdownlist.Models
{
    public class Model
    {
        public string selectedType { get; set; }
        public IEnumerable<selectlistitem> CountryList { get; set; }
    }
}
</selectlistitem>


Then prepare data source in controller and send the data through return View() method


Controller code:

using System;
using System.Collections.Generic;
using System.Web.Mvc;
using Dropdownlist.Models;
 
namespace Dropdownlist.Controllers
{
    public class HomeController : Controller
    {
 
        public ActionResult Index()
        {
            //Using ViewBag
            List<selectlistitem> item = new List<selectlistitem>();
            item.Add(new SelectListItem { Text = "India", Value = "1" });
            item.Add(new SelectListItem { Text = "China", Value = "2" });
            item.Add(new SelectListItem { Text = "United Sates", Value = "3" });
            item.Add(new SelectListItem { Text = "Srilanka", Value = "4" });
            item.Add(new SelectListItem { Text = "Germany", Value = "5" });
            ViewBag.html_helper_dropdown = item;
 
            //using ViewData
            ViewData["viewdata_ddl"] = item;
 
            //using Model binding
            var model = new Model
            {
                CountryList = item
             };
            return View(model);
        }
 
    }
}
</selectlistitem></selectlistitem>

View code as follows:

<p>Using Model </p>
@using (Html.BeginForm())
{
    @Html.DropDownListFor(x=>x.selectedType,Model.CountryList,"--select--")
}


Index.cshtml:

@using Dropdownlist.Models
@model Model
@{
    ViewBag.Title = "Dropdown list demo";
}

<h1>Dropdown list</h1>
<h3>Drop downlist using HTML</h3>
<select id="html_dropdown">
    <option>--Select--</option>
    <option>India</option>
    <option>US</option>
    <option>China</option>
    <option>Russia</option>
    <option>United Kingdom</option>
</select>
<br/>
<h3>Using Html helpers </h3>
<p>Method 1:</p><br/>
<p>Here the data was sent from Controller through ViewBag</p>
@using (Html.BeginForm())
{
    @Html.DropDownList("html_helper_dropdown","--select--")
}
<br/>
<p>Method 2:</p>
<p>Using View data</p>
@using (Html.BeginForm())
{
    @Html.DropDownList("viewbag_dropdown",ViewData["viewdata_ddl"] as List<SelectListItem>, "--select--")
}
<p>Method 3:</p>
<p>Using Model </p>
@using (Html.BeginForm())
{
    @Html.DropDownListFor(x=>x.selectedType,Model.CountryList,"--select--")
}

Note: We can also bind the dropdownlist data using ENUM's and arrays also.But, above are the most reliable and used by many developers (in our company also developers uses this methods only.).
Finally i got output like this.

ASP.NET MVC 4 Hosting - HostForLIFE.eu :: How To Add MVC Model?

clock April 26, 2016 23:28 by author Anthony

Model–view–controller (MVC) is a software architectural pattern for implementing user interfaces on computers. It divides a given software application into three interconnected parts, so as to separate internal representations of information from the ways that information is presented to or accepted from the user.

Free ASP.NET Hosting - Europe

Traditionally used for desktop graphical user interfaces (GUIs), this architecture has become extremely popular for designing web applications.

MVC

The MVC(Model View Controller) separates an application into three main components.
This includes Model,View and Controller.
In this article, mainly explained about Models.


Models

Model represents an object. Model is resposible for maintaining the data
It respond to the request from view. It also respond to the instruction from controller for the updation.

Model objects retrieve and store model state in a database.
For example, a Student object might retrieve information from a StudentData Database, operate on it, and then write updated information back to a StudentData table in a SQL Server database.

In MVC, model both hold and manipulate application data. It contains all the application logic except view and controller logic

Model Folder contains the classes of application.


Model Adding

We can add models to our application with the following steps

  • A model folder will be present under the created application's Solution Explorer.

  • Right click on Model folder. A list will be appearing
  • Select 'Add' option from list.Then a new list will be coming.
  • Then select 'Class' option from list
  • A new window appearing.Here give the name for the new class or model and select 'Add'.(Say model name as SampleModel)
  • The newly added class will be appearing.That is, this will create a model class to the application.
  • Inside this class, we can add properties as per the requirements. Example is given below.

ASP.NET MVC 5 Hosting - HostForLIFE.eu :: How to Fix Error “Could not load file or assembly ‘Microsoft.Web.Infrastructure’”

clock September 9, 2014 08:17 by author Peter

When deploying an ASP.NET MVC 5 application, I wanted to deploy it on Windows Azure to test it. Thanks to Visual Studio, the deployment was really easy but, as soon as I tried to browse the website, I received the following error message:

Could not load file or assembly ‘Microsoft.Web.Infrastructure, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35′ or one of its dependencies. The system cannot find the file specified.

This is also one of a few component libraries that are needed for deploying an MVC application:

  • System.Web.Helpers.dll (required by the web.config)
  • System.Web.Mvc.dll
  • System.Web.Razor.dll
  • System.Web.WebPages.dll
  • System.Web.WebPages.Razor.dll
  • Microsoft.Web.Infrastructure.dll

The system libraries are installed with .NET 4, however, 'Microsoft.Web.Infrastructure.dll' is only installed when Visual Studio is installed on the machine.  Therefore, short of needing to install MVC and Visual Studio on a production environment, we need to deploy the libraries with out application - and we'd like to do so automatically.

As one possible fix, please try the following:
1. Run the following command in the Package Manager Console. (If you are using Visual Studio, this can be reached via menu options “Tools –> Library Package Manager –> Package Manager Console:)

PM> Install-Package Microsoft.Web.Infrastructure
You will see the following messages if it is successfully installed.
     Successfully installed 'Microsoft.Web.Infrastructure 1.0.0.0'.
   Successfully added 'Microsoft.Web.Infrastructure 1.0.0.0' to Web.

2. You will notice that Microsoft.Web.Infrastructure.dll has now been added as a Reference (can be seen in the references folder of your project in in Solution Explorer)
3. If you look at the properties of this reference you will notice that “Copy Local” has been set to “True” by default.
4. Now when you “Publish ” your project, Microsoft.Web.Infrastructure.dll will be deployed.

Full Trust European Hosting :: What is ASP.NET Full trust hosting?

clock July 28, 2011 06:01 by author Scott

Today we will talk more about - What is full trust hosting and what is modified full trust hosting? A lot of web developers building web applications turn to web hosting companies to host their website. Web hosting companies offer a variety of plans.

Two type of plans largely offered are -

1. Shared web hosting or Shared plans
2. Dedicated web hosting or Dedicated plans

Shared plans, are the most economical and practical for low-traffic websites, can have anywhere from 25 to 150 separated websites hosted from the same web server. When hosting multiple websites on the same server, it is important that one website cannot affect or harm another site. For example, both the web hosting company and its customers want to prevent one website from, say, reading the connect string information from Web.config of another website.

Microsoft’s ASP.NET web technology / language allows for web hosting companies to define trust levels, which dictate what operations are permitted by ASP.NET applications. A web hosting company can either use one of the preset trust levels - Full, High, Medium, Low, or Minimal - or can create a custom trust level.

Full trust is the default, allows ASP.NET applications to execute native code, to read from the Registry and Windows Event Log, and to read and write to files outside of the application’s virtual directory. In short, with full trust one web application could delete the entire contents of another web application.

Now most web hosting companies run in medium trust, which greatly reduces the potential for harm by limiting the set of operations an ASP.NET application can perform. But Medium trust will place a number of restrictions on an application, including limiting an application’s file access to within the virtual directory where the application lives. While the protection granted by medium trust is reassuring, its limited functionality can be a cause of worry for developers. There are a lot of web applications and components in the market which do require full trust to work as desired.

Now what will happen, in this scenario. In this case a lot of web hosts run the web applications as modified full trust, which is a modified version of full trust and web hosting companies block certain modules or permissions of full trust. e.g. you can change this full trust to be effective only for the needed functionality (or vice versa, disable it for the File IO). This can be done through the .NET Framework Configuration tools on the server (caspol.exe etc) but it will require some additional setup.

Also, there are ways of allowing applications run in full trust while still keeping them in a sandbox. Many respectable shared hosts do allow this as its required for applications like FlexWiki, but is something that must be requested.

And the good news for you is HostForLife.eu support FULL TRUST ASP.NET hosting. Our objective is to give the best support to our customers with an affordable and reliable price.
