# Writing a code in access

Posted on 2014-03-05

I am trying to write a code in access for an assignment for my students. There will be two fields:

field1 is where students enter numbers, long numbers possibly 20 numbers long.

They then hit a button
The button will write the number they entered in field one according to a code of 0=q, 1=w, 2=e, 3=r, 4=t, 5=y, 6=u, 7=i, 8=p, 9=a

The result will appear in field 2.

For example.

field1: 453
after hitting the button field two shows: tyr

Thanks!

Dim arrayname
Dim  i As Long, field1 As String, field2 As String
arrayname = Array("q", "w", "e", "r", "t", "y", "u", "i", "p", "a")
field1 = "453"
For i = 0 To Len(field1) - 1
field2 = field2 + arrayname(i)
Next
MsgBox field2
0

I think sample has errors, but it can be corrected:
``````Dim arrayname
Dim i As Long, field1 As String, field2 As String
arrayname = Array("q", "w", "e", "r", "t", "y", "u", "i", "p", "a")
field1 = "453"
If IsNumeric(field1) Then
field2 = ""
For i = 1 To Len(field1)
field2 = field2 + arrayname(CInt(Mid(field1, i, 1)))
Next
MsgBox field2
Else
MsgBox "Non-numeric symbols entered: ", field1
End If
``````

Let me start with an apology.  Please don't be offended.  I've been wanting to say this for some time and it looks like you have your answer so I'll just jump in.

Codes are limited lists of values - area codes, zip codes, department codes, etc.  Or an encrypted value.  During WWII, the British captured an enigma machine and with it were able to decipher the codes the Germans used to encrypt their messages.  "A" code is a member of a set of codes so 203 is the area code for most of Western Connecticut or "F" is the value for female in a list of gender codes, or "a" code could be the entire body of the tokens substituted for letters to encrypt a message.  The Germans used a different code for each day of the week.  So on Monday an "a" is coded as "t", on Tuesday it is "c", on Wednesday it is "x", etc.

Code is what a programmer writes. No article, no trailing s to make it plural.  It is singular and plural and never takes the article "a" although it can take the article "the".  We never say "a code" but we do say "the code".   A programmer might create "a" procedure or "a" function or "a" subroutine but he writes code.  Not "a" code, not "codes".  Just code.

Thanks guys... appreciate your help. I am sure it is my fault, but I can't get it to work properly. It keeps opening of dialogue box with just the "tyr". I would it to take whatever was in the raw1 field and write it in the code for the saved1. Also note... my students may be entering very long numbers, up to 20 digits long. Not sure if this will affect anything. Thanks for all the help! Pat... very interesting, thanks!

I am using the below code for my on click of the button.

Private Sub Command42_Click()

Dim arrayname
Dim i As Long, raw1 As String, saved1 As String
arrayname = Array("q", "w", "e", "r", "t", "y", "u", "i", "p", "a")
raw1 = "453"
If IsNumeric(raw1) Then
saved1 = ""
For i = 1 To Len(raw1)
saved1 = saved1 + arrayname(CInt(Mid(raw1, i, 1)))
Next
MsgBox saved1
Else
MsgBox "Non-numeric symbols entered: ", raw1
End If

Me.fldDateUpdated = Now()

End Sub

The problem was with your last message box.  You needed to concatenate raw1 using the &.
ConvertNum.accdb

Pat, thanks! It is working perfect on yours... on mine... when I hit the button, nothing shows up. The date and time stamp changes correctly but nothing shows up. The code I am using is below (I changed my names to txtInput and txtOutput

Private Sub Command42_Click()

Dim arrayname
Dim i As Long
Dim bNumeric As Boolean
arrayname = Array("q", "w", "e", "r", "t", "y", "u", "i", "p", "a")

bNumeric = True
Me.txtOutput = Null
For i = 1 To Len(Me.txtInput)
If IsNumeric(Mid(Me.txtInput, i, 1)) Then
Else
bNumeric = False
i = Len(Me.txtInput)
End If
Next

If bNumeric Then
Me.txtOutput = ""
For i = 1 To Len(Me.txtInput)
Me.txtOutput = Me.txtOutput + arrayname(CInt(Mid(Me.txtInput, i, 1)))
Next
Else
MsgBox "Non-numeric symbols entered: " & Me.txtInput, vbOKOnly
End If

Me.fldDateUpdated = Now()
End Sub

I copied the code and pasted it into the database I sent to you and it works fine.

Does the code compile in your database?

Are you sure you are using the correct control names?

That's not good... No clue how I pulled that off. I'll try to fix it.

Thanks! I am an idiot... the table type of that cell was number. Changed to text and it works perfect. Thanks!

I am now going to post a question for a button what will take it out of the letters and back to numbers. Maybe you can help with it.  Thanks for everything this morning.
