- 6. You are a developer for a XYZ Inc that provides free software over the Internet. You are developing en e-mail application that users all over the world can download. The application displays text strings in the user interface. At run time, these text strings must appear in the language that is appropriate to the locale setting of the computer running the application. You have resources to develop versions of the application for only four different cultures.You must ensure that your application will also be usable by people of other cultures. How should you prepare the application for deployment?
Options- A. Package a different assembly for each culture.
- B. Package a different executable file for each culture.
- C. Package a main assembly for source code and the default culture. Package satellite assemblies for the other cultures.
- D. Package a main assembly for source code. Package satellite assemblies for each culture. Discuss
- 7. You work as software developer at XYZ inc. You need to develop a Windows form that provides online help for users. You want the help functionality to be available when users press the F1 key. Help text will be displayed in a pop-up window for the text box that has focus. To implement this functionality, you need to call a method of the HelpProvider control and pass the text box and the help text. What should you do?
Options- A. SetShowHelp
- B. SetHelpString
- C. SetHelpKeyword
- D. ToString Discuss
- 8. You develop a Windows-based application that enables to enter product sales. You add a subroutine named XYZ. You discover that XYZ sometimes raises an IOException during execution. To address this problem you create two additional subroutines named LogError and CleanUp. These subroutines are governed by the following rules: ? LogError must be called only when XYZ raises an exception. ? CleanUp must be called whenever XYZ is complete. You must ensure that your application adheres to these rules. Which code segment should you use?
Options- A. try { XYZ(); LogError(); } catch (Exception e) { CleanUp(e); }
- B. try { XYZ(); } catch (Exception e) { LogError(e); CleanUp(); }
- C. try { XYZ(); } catch (Exception e) { LogError(e); } finally { CleanUp(); }
- D. try { XYZ(); } catch (Exception e) { CleanUp(e); } finally { LogError(); } Discuss
- 9. You responsible for maintaining an application that was written by a former colleague at XYZ. The application reads from and writes to log files located on the local network. The original author included the following debugging code to facilitate maintenance: try { Debug.WriteLine(?Inside Try?); throw(new IOException());} catch (IOException e) { Debug.WriteLine (?IOException Caught?);} catch (Exception e) { Debug.WriteLine(?Exception Caught?);}. finally { Debug.WriteLine (?Inside Finally?);} Debug.WriteLine (?After End Try?); Which output is produced by thus code?
Options- A. Inside Try Exception Caught IOException Caught Inside Finally After End Try
- B. Inside Try Exception Caught Inside Finally After End Try
- C. Inside Try IOException Caught Inside Finally After End Try
- D. Inside Try IOException Caught Inside Finally Discuss
- 10. You use Visual Studio .NET to create a Windows-based application. The application includes a form named XYZProcedures (EXP). EXP allows users to enter very lengthy text into a database. When users click the Print button located on EXP, this text must be printed by the default printer. You implement the printing functionality by using the native .NET System Class Libraries with all default settings. Users report that only the first page of the text is being printed. How should you correct this problem?
Options- A. In the BeginPrint event, set the HasMorePages property of the PrintEventArgs object to True.
- B. In the EndPrint event, set the HasMorePages property of the PrintEventArgs object to True.
- C. In the PrintPage event, set the HasMorePages property of the PrintPageEventArgs object to True.
- D. In the QueryPageSettings event, set the HasMorePages property of the QueryPageSettingEventArgs object to True. Discuss

Correct Answer: Apply the FunctionAttribute and ResultTypeAttribute to the stored procedure function. Use the GetResult
Correct Answer: context.MergeOption = MergeOption.PreserveChanges;
Correct Answer: AESCryptoServiceProvider
Correct Answer: Set the Value property of the EntityReference of the Order entity.
Correct Answer: ordersFK.DeleteRule = Rule.None;
Correct Answer: Package a main assembly for source code and the default culture. Package satellite assemblies for the other cultures.
Explanation:
When you build a project, the resource files are compiled and then embedded in satellite assemblies, or assemblies which contain only the localized resources. The fallback resources are built into the main assembly, which also contains the application code.
Correct Answer: SetHelpString
Explanation:
To associate a specific Help string with another control, use the SetHelpString method. The string that you associate with a control using this method is displayed in a pop-up window when the user presses the F1 key while the control has focus.
Correct Answer: try { XYZ(); } catch (Exception e) { LogError(e); } finally { CleanUp(); }
Explanation:
We must use a try?catch?finally construct. First we run the Comapany() code in the try block.Then we use the LogError() subroutine in the catch statement since all exceptions are handled here. Lastly we put the CleanUp() subroutine in the finally statement since this code will be executed regardless of whether an exception is thrown or not.
Correct Answer: Inside Try IOException Caught Inside Finally After End Try
Explanation:
First the try code runs. Then one single exception, the IOException occurs, not two exceptions.Then the Finally code segments executes. After Finally code bas been executed normal application resumes at the next line after the line that called the error. In this case, the After End Try code runs.
Correct Answer: In the PrintPage event, set the HasMorePages property of the PrintPageEventArgs object to True.
Explanation:
PrintDocument.PrintPage Event occurs when the output to print for the current page is needed. This event has the HasMorePages property which gets or sets a value indicating whether an additional page should be printed.
