Programming Experience
Beginner
Ok trying to write 2 programs and stuck with them both only at 1 point.
I'm new to VB, and Programing in general. Any help would be great thanks.

ok for the first program, I need to beable to enter R,I,D for the politcal parties, then the age of the politcal member. It then writes those to peices of information a file. I now need to display the totals of # of R,I,D.
I got that, but now i need to display the Total # ages in Groups
as in 18-35, 36-50 and so on. This is the code i have now.
VB.NET: 
[SIZE=2][COLOR=#0000ff]Try[/COLOR][/SIZE]
[SIZE=2][COLOR=#008000]'create a stream reader object by opening the file for input[/COLOR][/SIZE]
[SIZE=2]paoStreamReader = IO.File.OpenText("pao.txt")[/SIZE]
[SIZE=2][COLOR=#008000]'process the loop instructions until there are no more characters to read[/COLOR][/SIZE]
[SIZE=2][COLOR=#0000ff]Do[/COLOR][/SIZE][SIZE=2][COLOR=#0000ff]Until[/COLOR][/SIZE][SIZE=2] paoStreamReader.Peek() = -1[/SIZE]
[SIZE=2][COLOR=#008000]'read, a record from the file[/COLOR][/SIZE]
[SIZE=2]record = paoStreamReader.ReadLine()[/SIZE]
 
[SIZE=2][COLOR=#008000]'update the appropriate couter[/COLOR][/SIZE]
[SIZE=2][COLOR=#0000ff]If[/COLOR][/SIZE][SIZE=2] record.StartsWith("D") [/SIZE][SIZE=2][COLOR=#0000ff]Then[/COLOR][/SIZE]
[SIZE=2]totalDem = totalDem + 1[/SIZE]
[SIZE=2][COLOR=#0000ff]ElseIf[/COLOR][/SIZE][SIZE=2] record.StartsWith("R") [/SIZE][SIZE=2][COLOR=#0000ff]Then[/COLOR][/SIZE]
[SIZE=2]totalRep = totalRep + 1[/SIZE]
[SIZE=2][COLOR=#0000ff]Else[/COLOR][/SIZE]
[SIZE=2]totalInd = totalInd + 1[/SIZE]
[SIZE=2][COLOR=#0000ff]End[/COLOR][/SIZE][SIZE=2][COLOR=#0000ff]If[/COLOR][/SIZE]
[SIZE=2][COLOR=#0000ff]Loop[/COLOR][/SIZE]
This gives me the totals, and then i can display them..
But i cant figure out how to get the Age Goups to work.

I tried doing this for the age groups.
VB.NET: 
[SIZE=2][COLOR=#008000]'count age groups[/COLOR][/SIZE]
[SIZE=2][COLOR=#0000ff]Do[/COLOR][/SIZE][SIZE=2][COLOR=#0000ff]Until[/COLOR][/SIZE][SIZE=2] paoStreamReader.Peek() = -1[/SIZE]
[SIZE=2]age = paoStreamReader.ReadLine()[/SIZE]
[SIZE=2][COLOR=#0000ff]If[/COLOR][/SIZE][SIZE=2] age <= 35 [/SIZE][SIZE=2][COLOR=#0000ff]Then[/COLOR][/SIZE]
[SIZE=2]totalAgeG1835 = totalAgeG1835 + 1[/SIZE]
But i cant use the Stream Reader as a Read Line. Can anyone help me on this program?



NEXT PROGRAM

ok now for the next program I need to write a password program
that creates new passwords. The user enters a new password in the program then after clicking create password

i need to replace all vowels with the letter X
then replace all Numbers with letter Z
then Reverse the Characters in the password.
then display the new password. I looked everywhere in my book and can not figure this program out for the life of me.

thanks for the help..

Pawn.

Here is a start on the second program. It will switch the numbers to 'Z' and reverse your string. I will let you do the vowels yourself to practise!

VB.NET: 
        Dim passText As String = TextBox1.Text

        For i As Integer = 0 To passText.Length - 1 'I dont think the password would be big so a simple for statement would do.
            If IsNumeric(passText.Chars(i)) Then
                passText = passText.Replace(passText.Chars(i), "Z")
            End If

        Next

        passText = Microsoft.VisualBasic.StrReverse(passText)
        TextBox1.Text = passText
    End Sub
As for the first program can you upload a sample text file so I can actually work on it?

or do you want me to copy and paste the whole program?

here's a suggestion, read the file(s) into a collection first then add/remove/modify the data as needed (also getting the age group will be faster from a collection than reading the hard drive over and over again) then write the file when exiting the program
