- D. Inside Try IOException Caught Inside Finally Discuss
- 8. 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
- 9. You create an assembly by using Visual Studio .NET. The assembly is responsible for writing and reading order entry information to and from an XML data file. The assembly also writes and reads values to and from the Windows registry while it is being consumed. The assembly will be distributed to client computers by using your company, XYZ, intranet. All client computers are configured to implement the default .NET security policy. You need to implement security in the assembly. What should you do?
Options- A. Implement declarative security and execute the permission demand to allow access to the file system and Windows registry.
- B. Implement declarative security and execute the minimum permission request to allow access to the file system and Windows registry.
- C. Implement imperative security and execute the permission demand to allow access to the file system and Windows registry.
- D. Implement imperative security and execute the minimum permission request to allow access to the file system and Windows registry. Discuss
- 10. You use Visual Studio .NET to create an assembly, called XYZAssembly, that will be used by other applications, including a standard COM client application. You must deploy your assembly on the COM application to a client computer. You must ensure that the COM application can instantiate components within the assembly as COM components. What should you do?
Options- A. Create a strong name of the assembly by using the Strong Name tool (Sn.exe).
- B. Generate a type library for the assembly by using the Type Library Importer (Tlbimp.exe). Register the file on the client computer.
- C. Generate a registry file for the assembly by using the Assembly Registration tool (Regasm.exe) Register the file on the client computer.
- D. Deploy the assembly to the global assembly cache on the client computer. Add a reference to the assembly in the COM client application. Discuss

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: Call the CreateObject method of the Customer object.
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: 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.
Correct Answer: Implement declarative security and execute the minimum permission request to allow access to the file system and Windows registry.
Explanation:
You can use declarative code access security to request permissions for the entire assembly. SecurityAction flags that can be specified in an assembly-wide directive. When SecurityAction.RequestMinimum is specified, it makes a request to the common language runtime to be granted the requested permission. If the requested permission is not granted by the security policy, the assembly will not execute. A Security Action.RequestOptional is similar, but the assembly will still run even if the requested permission is not granted. Specifying security Action. RequestRefuse requests that the assembly be denied the specified permission.
You must use the Assembly (assembly) directive when specifying these actions as follows:
Option A:
There are only three Security actionAttributes targets for an assembly: RequestMinimumAssembly, RequestOptionalAssembly, and RequestRefuseAssembly.
Option C, D:
Imperative security does not work well to configure security for an entire assembly. In imperative security, permission to execute is demanded at run time.
Correct Answer: Generate a registry file for the assembly by using the Assembly Registration tool (Regasm.exe) Register the file on the client computer.
Explanation:
The Assembly Registration tool reads the metadata within an assembly and adds the necessary entries to the registry, which allows COM clients to create .NET Framework classes transparently. Once a class is registered, any COM client can use it as though the class were a COM class..
Incorrect Answers:
Option A:
The Strong Name tool helps sign assemblies with strong names.
Option B:
The Type Library Importer, tlbimp.exe, converts the type definitions found within a COM type library into equivalent definitions in a common language runtime assembly. It would not be useful in this scenario however.
Option D:
This would not allow the COM application to use the class.
