.NetCluster

It is an error to use a section registered as allowDefinition="MachineToApplication" beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.

Answer:-

I am working .net application. I have this error when i open my application solution file and build my application that time getting this error.

and then i referred in this link.

he mentioned about I won't open the parent folder solution file. that's the reason happens this error.

Basically, the error means that there is a web.config file in one of your subfolders that has a configuration element that it should not have. Is this you root/only web config file? If not, could you please post those as well? Also, it sounds stupid, but I would double check that you're opening the website itself in your IDE (and not mistakenly opening a parent folder) I have seen people spend a couple hours trying to debug this same error, when all along they weren't in the right directory. Here is a good explanation on how the web.config hierarchy is set up for ASP that will help you visualize how this works:

Multiple CustomActionData fields

2014-03-11T08:02:00.001+05:30

This is multiple CustomActionData field pass in SetUp file.

it is possible to add one or more custom screens in the setup wizard, with fields (e.g. text boxes) where the user can enter additional installation parameters.

A custom field can then be passed to a "Custom Action" class library project, to handle the user field. The image below shows how the property "ServerName" gets mapped to the EDITB1 text field:

Within the Custom Action class, the property is accessed as follows:

string targetdir = Context.Parameters["TARGETDIR"];
string stationname = Context.Parameters["STATIONNAME"];
string facility = Context.Parameters["FACILITY"];
string line = Context.Parameters["Line"];
string email = Context.Parameters["Email"];
string environment = Context.Parameters["ENVIRONMENT"];

/TARGETDIR="[TARGETDIR]\" /STATIONNAME="[STATIONNAME]" /FACILITY="[FACILITY]" /LINE="[LINE]" /EMAIL="[EMAIL]" /ENV="[ENVIRONMENT]"

                Console.WriteLine("Device ID: {0}, PNP Device ID: {1}, Description: {2}",
                    usbDevice.DeviceID, usbDevice.PNPDevideID, usbDevice.Description);
            }

            Console.Read();
        }


        static List<USBDeviceInfo> GetUSBDevices()

            foreach (var device in collection)
            {
                devices.Add(new USBDeviceInfo(
                (string)device.GetPropertyValue("DeviceID"),
                (string)device.GetPropertyValue("PNPDeviceID"),

LINQ using XML data load to combobox.

2014-01-23T20:40:00.002+05:30

To use LINQ to XML you will need to import a two of namespaces.

using System.Linq;
using System.Xml.Linq;


private void StudentsLoad()
{
  var xElem = XElement.Load(@"Student.xml");

  var students = from prod in xElem.Descendants("Student")
           orderby prod.Element("StudentName").Value
           select prod.Element("StudentName").Value;

  lstStudents.DataContext = students;
}

Statically Load XML Data to the wpf combobox (drowpdown list) in wpf application

2014-01-23T20:35:00.001+05:30

When i want to xml data load to the combobox . i got this solution. Its very simple to load the xml data. this the xml data.

<Items>
  <Item>
    <ItemId>1</ItemId>
    <ItemName>Architecting ASP.NET Applications
                 eBook</ItemName>
    <Price>19.95</Price>
  </Item>
  <Item>
    <ItemId>2</ItemId>
    <ItemName>Fundamentals of N-Tier eBook</ItemName>
    <Price>19.95</Price>
  </Item>
     ...
     ...
  <Item>
    <ItemId>3</ItemId>
    <ItemName>Security for ASP.NET Developers
                 eBook</ItemName>
    <Price>19.95</Price>
  </Item>
</Items>

this is stackpanel resource load, it will load on window loaded

<StackPanel.Resources>
  <XmlDataProvider x:Key="ItemsData"
                   Source="/Items.xml"
                   XPath="Items/Item" />
</StackPanel.Resources>

Its a combobox wirte like this, i loaded in ItemName if you want price load to another one combobox just change the xPath and then automatically load the price data to the combobox.

<ComboBox Name="Items" MinWidth="200" Style="{StaticResource RequiredComboBox}" Foreground="Black" FontSize="30" IsSynchronizedWithCurrentItem="False" SelectedIndex="0">
                    <ComboBox.ItemContainerStyle>
                        <Style TargetType="ComboBoxItem">
                            <Setter Property="Padding" Value="5">
                            </Setter>
                        </Style>
                    </ComboBox.ItemContainerStyle>
                    <ComboBox.ItemsSource>
                        <Binding Source="{StaticResource ItemsData}" XPath="ItemName" />
                    </ComboBox.ItemsSource>
                </ComboBox>

</ResourceDictionary>

after that create and main window xaml file and then just call this RoundButtonTemplate style using Window.Resources load the GlassButton.xaml file and then call the StaticResource in main window like this.

<Window x:Class="GlassButton.Window1"

    Title="Glass Buttons" Height="228" Width="272">

    <Window.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="Resources\GlassButton.xaml"/>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Window.Resources>
<Grid>
 <StackPanel Orientation="Horizontal">
<Button Focusable="False"
        Style="{StaticResource RoundButtonTemplate}"

2014-01-21T21:40:00.003+05:30

This is code i have an exprience when i want to create a round button in my application i have used this code. this is one way of the create round button in wpf application. if we want change the color and Radial Gradient color and also we can able to apply the Transform using opacity. its very useful i have past the following code.

<Button Width="100" Height="100">
                <Button.Template>
                    <ControlTemplate TargetType="Button">
                        <Grid>
                            <Ellipse Stroke="#5ECF5E"
                         StrokeThickness="2">
                                <Ellipse.Fill>
                                    <RadialGradientBrush GradientOrigin="0.496,1.052">
                                        <RadialGradientBrush.RelativeTransform>
                                            <TransformGroup>
                                                <ScaleTransform CenterX="0.5" CenterY="0.5" ScaleX="1.5" ScaleY="1.5"/>
                                                <TranslateTransform X="0.02" Y="0.2"/>
                                            </TransformGroup>
                                        </RadialGradientBrush.RelativeTransform>
                                        <GradientStop Offset="1" Color="#5ECF5E"/>
                                        <GradientStop Offset="0.2" Color="#FFFFFFFF"/>
                                    </RadialGradientBrush>
                                </Ellipse.Fill>
                            </Ellipse>
                            <ContentPresenter HorizontalAlignment="Center"
                                  VerticalAlignment="Center"/>
                        </Grid>
                    </ControlTemplate>
                </Button.Template>
            </Button>

another one way to create the round button.

<Button  Width="100" Height="100" Content="Abcd">
        <Button.Template>
            <ControlTemplate TargetType="{x:Type Button}">
                <Grid>
                <Ellipse Fill="Red"/>
                    <ContentPresenter Content="{TemplateBinding Content}" HorizontalAlignment="Center" VerticalAlignment="Center"/>
                </Grid>
            </ControlTemplate>
        </Button.Template>
    </Button>

this code create an rectangle button with color and Radial Gradient color and also we can able to apply the Transform using opacity.

<UserControl x:Class="WindowsFormsApplication8.UserControl1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    <Grid>
        
        <Rectangle Name="rectangle1" Stroke="Black" RadiusX="10" RadiusY="10" >
        </Rectangle>
 
        <Button Name="rectangle2" Foreground="Black" Margin="3,3,3,3" >
            <Button.Background >
                <LinearGradientBrush StartPoint="0,0" EndPoint="1,1">
                    <GradientStop Color="Green" Offset="0.0" />
                    <GradientStop Color="White" Offset="0.9" />
                </LinearGradientBrush>
            </Button.Background>
        </Button>
    </Grid>
</UserControl>

The target version of the .NET Framework in the project does not match the .NET Framework launch condition version '.NET Framework 4'. Update the version of the .NET Framework launch condition to match the target version of the.NET Framework in the Advanced Compile Options Dialog Box (VB) or the Application Page (C#, F#).

Form Textbox Value assign from another class

2014-01-04T18:40:00.001+05:30

When i click the button i want to assign the textbox value from another class.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WindowsFormsApplication2
{
    public partial class Form1 : Form
    {
        Download myDownload = new Download();
        static string textBoxString;
        public Form1()
        {
            InitializeComponent();
        }

        public static string TextboxText
        {
            set { textBoxString = value; }
        }

        private void button1_Click_1(object sender, EventArgs e)
        {
            myDownload.Do();
            textBox1.Text = textBoxString;
            textBox1.Invalidate();
        }
    }

    public class Download
    {
        public void Do()
        {
            Form1.TextboxText = "My text";
        }
    }
}

An even better solution would be to define the possible interactions in an interface, and let that interface be the contract between your form and the other class. That way the class is completely decoupled from the form, and can use anyting implementing the interface (which opens the door for far easier testing):

interface IYourForm
{
    string FirstName { get; set; }
}

In your form class:

class YourFormClass : Form, IYourForm
{
    // lots of other code here

    public string FirstName
    {
        get { return firstNameTextBox.Text; }
        set { firstNameTextBox.Text = value; }
    }
}

...and the class:

class SomeClass
{
    private readonly IYourForm form;
    public SomeClass(IYourForm form)
    {
        this.form = form;
    }

    // and so on

}

Windows installer error

2014-01-04T13:26:00.002+05:30

When i install my wpf installer while getting error like this. any body know about this issue.

Question :-

Error 1001. Unable to get installer types in the C:\\YM\ConfigUI\ConfigUI.exe assembly. --> Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.

The description for Event ID 11001 from source MsiInstaller cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event: Product: YottaMark Case Labeling Solution -- Error 1001. Error 1001. Unable to get installer types in the C:\YM\ConfigUI\ConfigUI.exe assembly. --> Unable to load one or more of the requested types. Retrieve the LoaderExceptions property for more information.
(NULL)
(NULL)
(NULL)
(NULL)
(NULL)
the message resource is present but the message is not found in the string/message table

Answer : -

Based on the error message in your second comment, it appears that your ConfigUI.exe assembly has been added as a Custom Action with the InstallerClass property set to true, but either no installer classes could be found in the exe or the exe could not be loaded due to missing dependencies.

You can see the list of Custom Actions by right-clicking on the installer project, selecting View and then Custom Actions.

If your exe does not can an installer class, then you can remove it from the list of custom actions.

If it does contain an installer class, then the issue is going to be missing dependencies. If fuslogvw doesn't work for you (it has always helped resolve this kind of issue for us), you can carefully review the list of references in the exe's project and compare them to what is listed in the installer project.

The other trick that we use is to examine the install directory while the error message is displayed on the screen. We can often see that DLLs are missing by doing this, usually because the path was entered incorrectly in the DLL entry within the installer project or because a condition was set incorrectly.

Application Manifest Schema:

2013-12-20T00:41:00.002+05:30

Application manifests are not new to the Windows Vista release. Manifests were used in Windows XP to help application developers identify such things as which versions of DLLs the application was tested with. Providing the execution level is an extension to that existing application manifest schema. The Windows Vista application manifest has been enhanced with attributes that permit developers to mark their applications with a requested execution level. The following is the format for this:

<requestedExecutionLevel
level="asInvoker|highestAvailable|requireAdministrator"
uiAccess="true|false"/>

Your application will prompt for elevation if the user is an administrator and UAC is enabled

<trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
  <security>
   <requestedPrivileges xmlns="urn:schemas-microsoft-com:asm.v3">
    <!-- UAC Manifest Options
      If you want to change the Windows User Account Control level replace the 
      requestedExecutionLevel node with one of the following.

    <requestedExecutionLevel level="asInvoker" uiAccess="false" />
    <requestedExecutionLevel level="requireAdministrator" uiAccess="false" />
    <requestedExecutionLevel level="highestAvailable" uiAccess="false" />

      Specifying requestedExecutionLevel node will disable file and registry virtualization.
      If you want to utilize File and Registry Virtualization for backward 
      compatibility then delete the requestedExecutionLevel node.
    -->
    <requestedExecutionLevel level="highestAvailable" uiAccess="false" />
   </requestedPrivileges>
  </security>
 </trustInfo>

                if ((sc.Status.Equals(ServiceControllerStatus.Stopped)))
                {
                    sc.Start();

                    MessageBox.Show("Starting the  YottaMark Code Dispenser");
                }

    </Grid>

Just copy this code and past your wpf xaml file side of the window after that

public void LoadEmploys()
        {
string employconfigFolder="D:\\Employ.xml"
            var doc = new XmlDocument();
            doc.Load(employconfigFolder);

            XmlNodeList employ = doc.GetElementsByTagName("Employ");

            List<EmployAttribute> authors = new List<EmployAttribute>();

            foreach (XmlNode item in employ)
            {
                bool defaultPrinter = false;

                authors.Add(new PrinterAttribute()
                {
                    Name = item.Attributes["Name"].Value,
                    Email = item.Attributes["Email"].Value,
                    DOB = item.Attributes["DOB"].Value,
                    Address1 = item.Attributes["Address1"].Value,
                    City = item.Attributes["City"].Value,
                    Country = item.Attributes["Country"].Value,
                });
            }
            MyDataGrid.ItemsSource = authors;
        }



 public class EmployAttribute
        {
            public string Name { get; set; }
            public string Email { get; set; }
            public string DOB { get; set; }
            public string Address1 { get; set; }
            public bool City { get; set; }
            public bool Country { get; set; }
        }

you can call LoadEmploys() method in your window_Loaded() its working fine.

How to method call using Timer in c#

2013-12-07T12:09:00.002+05:30

this code using the system timer we can call the method. i tried working good. its a easy way to call the method using Timer interval time. Following the sample code:

            aTimer = new System.Timers.Timer(10000);

            aTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent);

            aTimer.Interval = 2000;
            aTimer.Enabled = true;

            Console.WriteLine("Press the Enter key to exit the program.");
            Console.ReadLine();

How to refresh combobox XmlDataProvider data using C# (OR) "Exception error: Unable to cast object of type 'System.Windows.Data.XmlDataProvider' to type 'System.Windows.Data.CollectionContainer'."

2013-11-29T16:14:00.002+05:30

This solution i experienced. when i develop wpf application there i used combobox. when i try to add new student that time combobox items not reloaded. because of application loading time i loaded dynamically. so i don't no how to refresh the combobox list. After that i got this solution. when u add new item while after "objwindow.ShowDialog()" refresh the combobox.

 <ComboBox Name="Student" ItemsSource="{Binding Source={StaticResource Students}, XPath=Student/@StudentName}"
SelectionChanged="{pti:DelegateCreator student_Changed}" MinWidth="150"
Style="{StaticResource RequiredComboBox}" />

if you want to refresh from the controller your combobox name declare commonly like

ComboBox _studentList = FindLogicalNode(window, STUDENT_LIST) as ComboBox;

other wise your refresh from the xaml.cs file there your can declare like "this.FindResource"

private static void studentConfig_Click(object source, RoutedEventArgs args)
        {
            StudentConfiguration objwindow = new StudentConfiguration();
            objwindow.ShowDialog();
            (_studentList.FindResource("Students") as XmlDataProvider).Refresh();            
        }
