- Another developer creates data files by using a computer that runs a version of Microsoft Windows XP Professional distributed in France. These files contain financial transaction information, including dates, times, and monetary values. The data is stored in a culture-specific format. You develop an application that uses these data files. You must ensure that your application correctly interprets all the data, regardless of the Culture setting of the client operating system. Which code segment should you add to your application?   using System.Threading; using System.Globalization; Thread.CurrentThread.CurrentCulture=new CultureInfo(“fr-FR”);
- Another developer in your company uses Visual Studio .NET to create a component named MyComponent. You deploy MyComponent to a server. When you execute MyComponent, you receive the following error message: “System.Security.PolicyException: Failed to acquire required permissions.” As quickly as possible, you need to discover which permissions are required by MyComponent. What should you do?   Run the Permissions View tool (Permview.exe) on the server to view the permissions required by MyComponent.
- As a developer at Gsoft inc. you develop a Windows-based application by using Visual Studio .NET. The application tracks information about customers, orders, and shipping. Ten users will use this application on the client computers running Windows 2000 Professional.

You deploy the application by copying the contents of the project’s \bin folder to the client computers. Nine users report that the application runs as expected. One user receives the following error message when the application is first executed: “The dynamic link library mscoree.dll could not be found in the specified path C\ProgramFiles\Orders App;.;C:\WINNT\System32;C:\WINNT\System;C:\WINNT\System32;C:\WINNT;C:\WINNT\System32\Wbem.”

You need to correct this problem on the client computer. What should you do?   Install the redistribute package for the .NET Framework.
