2. You create a Windows Presentation Foundation application by using Microsoft .NET Framework 3.5.
The application is named EnterpriseApplication.exe.
You add the WindowSize parameter and the WindowPosition parameter to the Settings.settings file by
using the designer at the User Scope Level. The dimensions and position of the window are read from the
user configuration file.
The application must retain the original window size and position for each user who executes the
application.
You need to ensure that the following requirements are met:
The window dimensions for each user are saved in the user configuration file.
The user settings persist when a user exits the application.
Which configuration setting should you use?
A. private void OnClosing(object sender, System.ComponentModel.CancelEventArgs e){
Settings.Default.WindowPosition = new Point (this.Left, this.Top);
Settings.Default.WindowSize = new Size (this.Width, this.Height);
Settings.Default.Save();
}
B. private void OnClosing(object sender, System.ComponentModel.CancelEventArgs e){
RegistryKey appKey = Registry.CurrentUser.CreateSubKey(”Software\\EnterpriseApplication”);
RegistryKey settingsKey = appKey.CreateSubKey(”WindowSettings”);
RegistryKey windowPositionKey = settingsKey.CreateSubKey(”WindowPosition”);
RegistryKey windowSizeKey = settingsKey.CreateSubKey(”WindowSize”);
windowPositionKey.SetValue(”X”, this.Left);
windowPositionKey.SetValue(”Y”, this.Top);
windowSizeKey.SetValue(”Width”, this.Width);
windowSizeKey.SetValue(”Height”, this.Height);
}
C. private void OnClosing(object sender, System.ComponentModel.CancelEventArgs e){

XmlNode nodePosition = doc.SelectSingleNode(”//setting[@name=\'WindowPosition\']“);
nodePosition.ChildNodes[0].InnerText = String.Format(”{0},{1}”, this.Left, this.Top);
XmlNode nodeSize = doc.SelectSingleNode(”//setting[@name=\'WindowSize\']“);
nodeSize.ChildNodes[0].InnerText = String.Format(”{0},{1}”, this.Width, this.Height);
doc.Save(”UserConfigDistractor2.exe.config”);
}
D. private void Window_Closing(object sender, System.ComponentModel.CancelEventArgs e){
StreamWriter sw = new StreamWriter(”EnterpriseApplication.exe.config”, true);
sw.WriteLine(”<EnterpriseApplication.Properties.Settings>”);
sw.WriteLine(”<setting name=\”WindowSize\” serializeAs=\”String\”>”);
sw.WriteLine(String.Format(”<value>{0},{1}</value>”, this.Width, this.Height));
sw.WriteLine(”</setting>”);
sw.WriteLine(”<setting name=\”WindowPosition\” serializeAs=\”String\”>”);
sw.WriteLine(String.Format(”<value>{0},{1}</value>”, this.Left,this.Top));
sw.WriteLine(”</setting>”);
sw.WriteLine(”</UserConfigProblem.Properties.Settings>”);
sw.Close();
}
