Microsoft-PRO Designing and Developing Windows Applications Using the Microsoft .NET Framework 3.5 Set 5

You are creating a Windows application by using the .NET Framework 3.5. You plan to evaluate the design strategy of the application. The design strategy contains the following elements: The application uses the ClickOnce deployment. The application runs on computers that have the Microsoft Windows 98 operating system, a 256-MB RAM, and a 1-GB disk space. The application transmits the collected data to a server by using a Windows Communication Foundation (WCF) service. The application must meet the following requirements: It displays real-time data. It gathers data from a serial interface. The code written for it is small and can be easily deployed. You discover that the design strategy does not function properly. You need to ensure that the design strategy functions appropriately. What should you recommend?

You are creating a Windows application by using the .NET Framework 3.5. The application must import data from a legacy database. A comma-delimited text file that has 10,000 rows of data is exported from the database frequently. The data is displayed and processed by the Windows application. The text file is not trusted and can contain invalid data. The application database must store valid data. You need to create a strategy to optimally validate and process the application data. What should you do?

You are creating a Windows application by using the .NET Framework 3.5. The application has the following features: Users access the application from their local computers. Each user specifies the data file to be used for the current session at the start of the application. You plan to design a strategy to enable users to share their data files with other users. You need to implement the strategy to meet the following requirements: Users can open the data file only by using a password. Users can work on the data file only by using the application.
