Upgrading from ASP to ASP.NET
ASP.NET provides several benefits over ASP in state management, security, performance, scalability, output cache control, Web farm support, configuration, deployment, and XML Web service infrastructure. The use of the built-in objects of ASP, such as Application, Request, Response, Server, and Session, are the same in ASP.NET. These objects are defined in classes that the System.Web namespace provides.
Some structural differences exist between ASP and ASP.NET. The page layout and coding style may differ. ASP.NET also has different ways to manage programming languages, code blocks, and page directives.
You can migrate an ASP Web application to ASP.NET using the Migration Assistant tool. After converting the code, you need to optimize and fix the errors that arise due to incompatibilities in the migration process.
| Important | After converting the ASP application to an ASP.NET application, you can separate the business logic from the presentation logic and incorporate the server-side functionality by writing code-behind .vb or .cs files. |
Creating an ASP Application
Consider an application, Complaint Monitoring System, that allows the registration and monitoring of customer complaints for faulty machine parts and peripherals. An end user can log on to the application, register a complaint, and view the status of the complaint using the complaint number that the application provides. The administrator can log on to the application, view complaints, change the passwords of application users, enter remarks against each complaint, and update the status of the complaint.
The conn.asp file creates the connection object to establish a connection with the Complaint database. Listing 3-9 shows how to create the conn.asp file:
Listing 3-9: Creating the Conn.asp File
 |
<% set conn=Server.CreateObject("ADODB.Connection") conn.Open"Provider=SQLOLEDB.1; Persist Security Info=False; User ID=newlogin; password=password; Initial Catalog=Complaint;Data Source=SHOBHIT" %> |
In the above listing, the conn.asp file creates the conn connection object and establishes a connection with the Complaint SQL Server database using the SQLOLEDB provider. You need to include the conn.asp file in each .asp file of this application to access the database because this file provides the connection object.
The login.html file provides the Login page that allows the end user to specify and submit login credentials. The Login page also provides a link to the end user to check the status of their complaints. Listing 3-10 shows how to create the login.html file:

The above listing defines the following methods written in JavaScript:
-
callhome(): Loads the login.html page, which is the home page of the application.
-
validate(): Validates the data on the form.
-
name(): Checks whether the complainant name is blank or not. Returns true if the field is not blank and returns false if the field is blank.
-
problem(): Checks whether the problem field is blank or not. Returns true if the field is not blank and returns false if the field is blank.
-
txtmaccode_onBlur(): Executes when the focus exits the txtmaccode text box. This method retrieves the machine description for the specified machine code.
-
callback(): Displays the previous page in the browser.
-
txtpercode_onBlur(): Executes when the focus exits the txtpercode text box. This method retrieves the peripheral description of the specified peripheral code.
The above listing also shows the server-side script to retrieve location ID, department code, machine description, and peripheral description from the database. When the end user clicks Submit, the code redirects the end user to the comphandle.asp file.
The comphandle.asp file generates a complaint reference number based on the complaint information that the end user specifies. The end user uses the complaint reference number to check the status of the complaint. Listing 3-13 shows how to create the comphandle.asp file:

The above listing also defines server-side code to check whether the end user accessing the page is an administrator or not. Server-side code compares the string value contained in the LoginTest session variable with the string administrator. If the values do not match, the Web server redirects the end user to the Login page. The code redirects the administrator to the changepass.asp file when the administrator clicks the Change Password link, to the viewcomp.asp file when the administrator clicks the View Complaints link, and to the complaint.asp file when the administrator clicks the Complaint link.
The changepass.asp file provides the Change Password page that allows the administrator to select the user name, enter the old password, enter the new password, and confirm the new password. Listing 3-17 shows how to create the changepass.asp file:

The above listing defines the callhome() and callback() JavaScript methods.
The above listing also defines server-side code to retrieve user names from the database and load the user names in the UserId list box. The administrator selects the user name, enters the old password, enters the new password, confirms the new password, and clicks Submit. When the form is submitted, the entries are transmitted to the changepasshandle.asp file.
The changepasshandle.asp file provides the Process Password Change page that validates the password information that the administrator specifies on the Change Password page and updates the changes in the database. Listing 3-18 shows how to create the changepasshandle.asp file:

The above listing defines the callhome() and callback() JavaScript methods.
The above listing also defines server-side code to validate password information by comparing the entries that the administrator specifies on the Change Password page and the entries in the database. The code then updates the changes in the database if the validation is successful; otherwise, it displays error messages on the page.
The viewcomp.asp page provides the View Complaints page that displays the list of complaints in tabular format. The table contains various fields, such as complaint reference number, machine code, peripheral code, department code, date of complaint, date of rectification, down time, remarks, status, problem, complaint name, and location identity. This page enables the administrator to enter the date of rectification and remarks against the complaint. The code on this page automatically calculates the down time of the machine by calculating the difference between the date of complaint and the date of rectification. The administrator checks the status column and updates the complaint to mark the complaint as attended or resolved. The administrator can update the complaint without checking the status column to mark the complaint as partially solved. The administrator updates the complaints by clicking the links against the complaint numbers. Listing 3-19 shows how to create the viewcomp.asp file:

The above listing defines the following JavaScript methods:
-
callhome(): Loads the login.html page, which is the home page of the application.
-
callback(): Displays the previous page in the browser.
-
passvalue(): Sets the values of the controls on the form with the values passed to this function. The values are downtime, date, complaint ID, remarks, and status.
-
lostfocus(): Executes when focus is lost from the combo2 control that displays the date. This method checks whether the administrator selects a valid date or not.
-
calcdate(): Checks whether the date of rectification is greater than the date of complaint.
The above listing also defines the server-side control to retrieve complaint information from the database and display the list of complaints in tabular format. The code redirects the administrator to the responseview.asp file when the administrator clicks the complaint reference number of a complaint to be updated.
The responseview.asp file provides the Response View page that displays the message that the complaint is updated successfully. Listing 3-20 shows how to create the responseview.asp file:

Using the ASP to ASP.NET Migration Assistant
The ASP to ASP.NET Migration Assistant tool converts ASP applications to ASP.NET. It does not convert the entire application to ASP.NET. You need to perform some manual modifications to optimize the code after conversion. The Migration Assistant tool creates stand-alone .aspx pages corresponding to each .asp page in the ASP application.
| Important | You need to segregate the presentation logic and the business logic after the migration process. For each .aspx file, you need to create a code-behind file in which you can write the business logic. This code-behind file segregates the presentation and business logic. |
Before you use the Migration Assistant tool, back up your ASP application. Ensure your computer meets the requirements for installing the ASP to ASP.NET Migration Assistant tool. The operating systems you can use are Windows XP, Windows 2000, and Windows Server 2003. You also need .NET Framework, which is installed, by default, with Windows Server 2003 and Visual Studio .NET.
To migrate applications from ASP to ASP.NET using the ASP to ASP.NET Migration Assistant tool from within Visual Studio .NET:
-
Download and install the ASP to ASP.NET Migration Assistant.
-
After installing the Migration Assistant, open Visual Studio .NET.
-
Select File -->Open -->Convert from the menu bar to start the conversion process, as shown in Figure 3-1:
Figure 3-1: The Convert Option -
Select the ASP to ASP.NET Migration Assistant in the Convert dialog box. In addition, select Create new solution if you want to create a new set of files for the ASP.NET application. If you need to add the files to the opened application, select Add to current solution, as shown in Figure 3-2:
Figure 3-2: The Convert Dialog Box -
Click OK. The Welcome to ASP to ASP.NET Migration Assistant Wizard page appears, as shown in Figure 3-3:
Figure 3-3: The ASP to ASP.NET Migration Assistant Wizard Page -
Click Next. The Choose a directory of ASP files page appears, as shown in Figure 3-4:
Figure 3-4: The Choose a Directory of ASP Files Page -
Specify the path of the ASP project and click Next. The New Project Information page appears, as shown in Figure 3-5:
Figure 3-5: The New Project Information Page -

To migrate ASP applications to ASP.NET using the command line:
-
Open the Command window.
-
Type the following command to run the AspUpgrade.exe file:
ASPUpgrade[.exe] <DirectoryName> [/Out ] [/NoLog | /LogFile ] [/Verbose] [ /ProjectName ] [/ForceOverwrite]
| Note | You can type the following command for help: ASPUpgrade[.exe] /? or /Help |
The options used in the command line are:
-
Directory Name: Specifies the path of the ASP file to be upgraded.
-
/Out DirectoryName: Specifies the path for the folder where you plan to create the ASP.NET project, which is the target directory. The default path is \OutDir.
-
/Verbose: Displays the entire output to the MS-DOS window during upgrade.
-
/NoLog: Suppresses the writing a log file.
-
/LogFile filename: Specifies the name of the log file to generate. The default file name is <targetdirectory>\<projectname>.log.
-
/ProjectName: Specifies the project name for directory conversion. The default project name is Project1.
-
/ForceOverwrite: Suppresses prompting to confirm that you want to overwrite an existing destination directory.
-
/? or /Help: Displays all the command-line options.
Post Migration Considerations
The ASP to ASP.NET Migration Assistant tool converts the files of the ASP project to files with the .aspx extension. The migration tool removes all references of .asp files when it converts the files and changes them to .aspx extensions.
In ASP applications, created using VBScript, the variable declarations do not include data types or variables are sometimes undeclared. In this case, it is difficult to understand the variables properties and their methods. The Migration Assistant tool performs the necessary relocations of VBScript code to the equivalent script or renders tags in ASP.NET.
The Migration Assistant tool converts the code written only in VBScript. You obtain an Error Warning and Issues (EWI) if the scripting language used for server-side scripting is not VBScript.
The Migration Assistant tool does not convert the complex rendering methods, which distorts the design view of the Web pages opened in ASP.NET.
The tool also does not convert the security model. Security configuration in ASP.NET occurs in the Web.config file. When the automatic conversion process is over, you should review all the EWIs in the code and fix the errors.
