vb.net count characters then add a symbol
Posted on 2004-09-24
I am using visual basic and I want to know how I can count so many characters and then add a certain symbol
example that I have is:
L20Tom Brady 12340golf
It needs to be when the code sees the line that starts with L to
make the line look lke this
L:20:Tom:Brady:12340:Golf
Now the line data will never be the same but it will have the same fixed length. The L will be the identifier to signal to do the above,
So
where 20 is would be 2 characters
Tom = 4 five characters
Brady = 10 characters
12340 = 5 chars
Golf= 4 chars
so lets say the next line would be
L40JimmyBrad 123 base
it would do this to the line
L:40:Jimmy:Brad:123:base
striping out the empty spaces.
Is this hard to do????

do I understand you correctly that whent the FIRST CHARACTER is a 'L' the line will ALWAYS be laid out as
1 Character
2 DIGITS
5 Characters (may have trailing blanks)
10 Characters (may have trailing blanks)
5 Digits
4 characters
Is that correct?
AW
1 Character
2 DIGITS
5 Characters (may have trailing blanks)
10 Characters (may have trailing blanks)
5 Digits
4 characters
Is that correct?
AW
and are the other character counts ALWAYS the same
2 characters ('20' in your example) followed by
5 Characters ('Tom ' or 'Jimmy' in you examples) foloowed by
10 Characters ('Brady ' or 'Brad ' in your examples) followed by
5 Characters ('12340' in your example) followed by
4 characteres ('golf' or 'base' in your examples)

If that is the case, then use can use the SubString Method of the String Object, like this:
Dim strTest As String = "L20Tom Brady 12340golf"
Dim str(5) As String
Dim StrResult As String
str(0) = strTest.Substring(0, 1)
str(1) = strTest.Substring(1, 2)
str(2) = strTest.Substring(3, 5).Trim
str(3) = strTest.Substring(8, 10).Trim
str(4) = strTest.Substring(18, 5)
str(5) = strTest.Substring(23, 1).ToUpper & strTest.Substring(24, 3)
For i As Integer = 0 To 5
StrResult = StrResult & str(i) & ":"
Next
StrResult = StrResult.Substring(0, StrResult.Length - 1)
AW
Dim strTest As String = "L20Tom Brady 12340golf"
Dim str(5) As String
Dim StrResult As String
str(0) = strTest.Substring(0, 1)
str(1) = strTest.Substring(1, 2)
str(2) = strTest.Substring(3, 5).Trim
str(3) = strTest.Substring(8, 10).Trim
str(4) = strTest.Substring(18, 5)
str(5) = strTest.Substring(23, 1).ToUpper & strTest.Substring(24, 3)
For i As Integer = 0 To 5
StrResult = StrResult & str(i) & ":"
Next
StrResult = StrResult.Substring(0, StrResult.Length - 1)

Dim mainLine as string = "L40JimmyBrad 123 base "
Dim temp As String
Dim temp1 As String
Dim temp2 As String
Dim temp3 As String
Dim temp4 As String
Dim temp5 As String
temp = mainLine.Substring(0, 1)
temp1 = mainLine.Substring(2, 4)
temp2 = mainLine.Substring(5, 10)
temp3 = mainLine.Substring(11, 21)
temp4 = mainLine.Substring(22, 27)
temp5 = mainLine.Substring(28, 32)
Dim position1 As Int16 = temp1.IndexOf(" ")
Dim position2 As Int16 = temp2.IndexOf(" ")
Dim position3 As Int16 = temp3.IndexOf(" ")
Dim position4 As Int16 = temp4.IndexOf(" ")
Dim position5 As Int16 = temp5.IndexOf(" ")
If position1> 0 Then
temp1 = temp1.substring(0,position
End If
If position2> 0 Then
temp2 = temp2.substring(0,position
End If
If position3> 0 Then
temp3 = temp3.substring(0,position
End If
If position4> 0 Then
temp4 = temp4.substring(0,position
End If
If position5> 0 Then
temp5 = temp5.substring(0,position
End If
Dim resultline as string = temp + ":" + temp1 + ":" + temp2 + ":" + temp3 + ":" + temp4 + ":" + temp5
It might not be the best way to solve this problem... but still this will give you resulting string as you want
Best of luck

one question though: what is this line actually doing??
StrResult = StrResult.Substring(0, StrResult.Length - 1)
StrResult = StrResult.Substring(0, StrResult.Length - 1)
