The questionnaire asks each voter for his or her political party (Democratic, Republican, or Independent) and age. From the returned questionnaires, the organization's secretary tabulates the number of Democrats, Republicans, and Independents in the district. The secretary wants an application that she can use to save each respondent's information (political party and age) to a sequential access file. The application should also calculate and display the number of voters in each political party. Create a Visual Basic Windows application. Use the following names for the solution and project, respectively: PAO Solution and PAO Project. Save the application in the ClearlyVB20121Chap22 older.

Code the Click event procedures for the Write to File and Display Totals buttons. Save the solution and then start and test the application. Close the Code Editor window and then close the solution
