ASP.NET 3.5 Hosting – An Overview on the Advance ASP.NET 3.5 Technology
ASP.NET 3.5 is a web application that was created by Microsoft to allow web programmers to contrive web sites, web services, and web applications. ASP.NET is created upon the Common Language Runtime, which is more commonly known as CLR. This allows web programmers to write programming code using any .NET language that is supported.
ASP.NET 3.5 hosting has many great features and characteristics. One of these features is its NET pages, which are known as web forms. These web forms are the main factor when it comes to application development. These web forms are held in files, which contain static XHTML markup. In addition to the mark up them also markup-defining server side User and Web controls. This is where the web developers place all the needed static and content for the web page.
ASP.NET 3.5 creates reusable components through the development of User controls. A user control follows the same build as a Web Form. The only difference is that these controls come from the System.Web.UI.UserControl class. They are then stored in ASCX files. An ASCX file holds static HTML or XHTML markup. It also, contains defining web control and User Controls. Web programmers are able to use their own properties, event handlers, and methods.
Besides that, ASP.NET 3.5 also uses a composites rendering technique. During assemblage, the template file is compiled into initialization code, which then creates a control tree that represents the inventive template. Literal text goes into instances of the Literal control class, and the server controls are represented by instances of a certain control class. The initialization code is united by means of user written code. This results in a class precise for the page. The page doubles because it is the root of the control tree.
Master pages have been introduced along with this advance technology. Master pages allow template based page development. A web application can have just one master page, or it can have a plethora of them. In ASP.NET 3.5 master pages can now be nested. Master templates are equipped with place-holder controls, which are called “contentplaceholders.” These are used to indicate where the dynamic content is to go, as well as the HTML and JavaScript mutual across child pages.
Child pages use those ContentPlaceHolder controls. The ContentPlaceHolder controls have got to be mapped to the placeholder of the master page, which the content page is populating. What’s left of the page is defined by common parts of the master page. All of the server and markup controls that are located in the content page must be placed within the ContentPageHolder control.
ASP.NET 3.5 offers many great features, as is a commonly used web designer program. Microsoft has been advancing ASP.NET throughout the years. And they will probably come out with a more advanced version in the years to come.

How to Create Shortcut of Application programatically using C# | C#
There are some situations in which we need to code to create a short cut of our application especially when user loose the shortcuts created by the application after the setup has been run because some shortcuts also have defines special parameters that are for executable that runs program.
Step 1:
Create a New Windows Form Project.
Step 2:
Drag drop a button control from Toolbox to Form name it btnShortcut and Set text Property to “Create Shortcut “
Step 3:
For creating shortcut you need to reference Windows Script Host Object so follow the steps as below
Step 4:
Add namespace as below
using IWshRuntimeLibrary;
Step 5:
Now write code in Button’s Click event like below
private void btnShortcut_Click(object sender, EventArgs e)
{
WshShellClass shell = new WshShellClass();
IWshShortcut shortcut = (IWshShortcut)shell.CreateShortcut(@”D:\shotcut.lnk”);
shortcut.TargetPath = Application.ExecutablePath;
//shortcut.IconLocation = ‘Location of iCon you want to set”;
// add Description of Short cut
shortcut.Description = “Any Description here “;
// save it / create
shortcut.Save();
}
Drawing Shaped Forms and Windows Controls in GDI+
This article has been excerpted from book “Graphics Programming with GDI+”
Normally, all Windows controls and forms are rectangular, but what if we want to draw them in nonrectangular shapes? We can do this by setting the Region property. The Region property of a form or a control represents that window’s region, which is a collection of pixels within a form or control where the operating system permits drawing; no portion of a form that lies outside of the window region is displayed. To draw nonrectangular shapes, we trick the system into drawing only the region of a control.
Let’s draw a circular form. We can use the GraphicsPath class to draw graphics paths. In this application we’ll create a circular form and a circular picture box, which will display an image. To test this application, we follow these simple steps:
We create a Windows application and add a button and a picture box to the form. Then we set the Text property of the button control to “Exit” and write the following line on the button click event handler:
this.Close();
Next we add a reference to the System.Drawing.Drawing2D namespace that we can use the GraphicsPath class:
using System.Drawing.Drawing2D;
On the form-load event handler, we create a Bitmap object from a file and load the bitmap in the picture box shown in the following code snippet.
Image bmp = Bitmap.FromFile(“aphoto.jpg”;
pictureBox1.Image = bmp;
The last step is to set the form and picture box as circular. We can modify the InitializeComponent method and add code as in Listing 15.5 at the end of the method, or we can add the code on the form-load event handler. We just set the Region property of the form and picture box to the region of our GraphicsPath object.
Setting a form and picture box control as circular
private void Form1_Load(object sender, System.EventArgs e)
{
//Create a rectangle
Rectangle rect = new Rectangle(0, 0, 100, 100);
//Create a graphic path
GraphicsPath path = new GraphicsPath();
//Add an ellipse to the graphics path
path.AddEllipse(rect);
//Set the Region property of the picture box
//by creating a region form the path
pictureBox1.Region = new Region(path);
rect.Height += 200;
rect.Width += 200;
path.Reset();
path.AddEllipse(rect);
this.Region = new Region(path);
//Create an image from a file and
//set the picture box’s Image property
Image bmp = Bitmap.FromFile(“aphoto.jpg”);
pictureBox1.Image = bmp;
}
Drawing a circular form and Windows controls
When we build and run the application; the output will look like Figure 15.3. Because we have eliminated the normal title bar controls, we must implement an Exit button.
Getting detailed Information about Windows User Accounts with WMI and C#
This article is aimed about how to get detailed information about Windows user accounts like accounts SID, SID type, Name, caption, Account domain and whether Account Status is OK, degraded unknown etc through WMI.
To access account information of windows users we need to Use System.Management name space.
To use this namespace first of all we need to add reference to System.management by
Project Menu>>Add Reference.
after that at the top of the code use
using System.Management; so that you can use of its classes .
Now its simple to get information about any Windows user Account through querying ManagementObjectSearcher Class .
we can get all information about Windows User through Win32_Account class .
so we need to query on that class to get related Management object and then we just need to get various properties related to it .

Get Laptop Battery Status using C# and WMI
In this article I will show you how to show battery status of laptop battery like its battery is discharging, charging, full etc. We will do this using WMI because WMI have power to answer questions about battery status .So let’s start with WMI.
To use this name space first of all we need to add reference to System.management by
Project Menu>>Add Reference.
after that at the top of the code use
using System.Management;
so that you can use of its classes .Now its simple to get information about any Windows user Account through querying ManagementObjectSearcher Class .
We can get all information about Laptop Battery through Win32_Battery class.
so we need to query on that class to get related Management object and then we just need to get various properties related to it . Here i have taken two labels one textbox with read only property and one progress bar and a timer control .
now to get battery status we need to code like below .
Dictionary
private void Form1_Load(object sender, EventArgs e)
{
StatusCodes = new Dictionary
StatusCodes.Add(1, “The battery is discharging”);
StatusCodes.Add(2, “The system has access to AC so no battery is being discharged. However, the battery is not necessarily charging”);
StatusCodes.Add(3, “Fully Charged”);
StatusCodes.Add(4, “Low”);
StatusCodes.Add(5, “Critical”);
StatusCodes.Add(6, “Charging”);
StatusCodes.Add(7, “Charging and High”);
StatusCodes.Add(8, “Charging and Low”);
StatusCodes.Add(9, “Undefined”);
StatusCodes.Add(10,”Partially Charged”);
/* Set progress bar values and Properties */
progressBar1.Maximum = 100;
progressBar1.Style = ProgressBarStyle.Continuous;
timer1.Enabled = true;
ManagementObjectSearcher mos = new ManagementObjectSearcher(“select * from Win32_Battery”);
foreach (ManagementObject mo in mos.Get())
{
lblBatteryName.Text = mo["Name"].ToString();
UInt16 statuscode = (UInt16)mo["BatteryStatus"];
string statusString = StatusCodes[statuscode];
lblBatteryStatus.Text = statusString;
}
}
private void timer1_Tick(object sender, EventArgs e)
{
ManagementObjectSearcher mos = new ManagementObjectSearcher(“select * from Win32_Battery where Name=’”+lblBatteryName.Text+”‘”);
foreach (ManagementObject mo in mos.Get())
{
UInt16 statuscode = (UInt16)mo["BatteryStatus"];
string statusString = StatusCodes[statuscode];
lblBatteryStatus.Text = statusString;
/* Set Progress bar according to status */
if (statuscode == 4)
{
progressBar1.ForeColor = Color.Red;
progressBar1.Value = 5;
}
else if (statuscode == 3)
{
progressBar1.ForeColor = Color.Blue;
progressBar1.Value = 100;
}
else if (statuscode == 2)
{
progressBar1.ForeColor = Color.Green;
progressBar1.Value = 100;
}
else if (statuscode == 5)
{
progressBar1.ForeColor = Color.Red;
progressBar1.Value = 1;
}
else if (statuscode == 6)
{
progressBar1.ForeColor = Color.Blue;
progressBar1.Value = 100;
}
}
}
Here i have used few status only to show in progress bar you can code whatever you want to show in progress bar..
Thank you
A generic error occurred in GDI+
ISSUE :
System.Runtime.InteropServices.ExternalException: “A generic error occurred in GDI+.” Issue occurred: When you are trying to save the image.
SOLUTION:
The System.Runtime.InteropServices namespace provides a wide variety of members that support COM interop and platform invoke services. If you are unfamiliar with these services, see Interoperating with Unmanaged Code.
The System.Runtime.InteropServices namespace provides a collection of classes useful for accessing COM objects, and native APIs from .NET. The types in this namespace fall into the following areas of functionality: attributes, exceptions, managed definitions of COM types, wrappers, type converters, and the Marshal class.
A generic error occurred in GDI+, one of the most common error occured while saving the image into the directory, the error occured because of the several reasons including the permission on the folder to write, which can be done by right click on the folder and assign write permission to the user. Some times, you get this error when someone else is using the same file on which you are performing the operation, the better solution is to lock the file when it is use and dispose the object when you are done.Â
I have illustrated the series of cause and remedy in my article.
Please check this article for complete detail: http://tinyurl.com/25khl98
Your comments and suggestions are highly appreciated. kindly let me know if the tutorial is not able to solve your issue.
