Is there any way for a program to look at the text in, for example rtbInput and examine each letter individually as it goes? I mean, if the text in rtbInput is: How do I get the program to look at the text as 5 different strings: "H", "e", "l", "l" and "o"?

I've got my self in to a pickle here.I'm trying to do something I used to do in basic? At-least I think you can do this in Basic, you know Qbasic,What I'm trying to do is put 4-8 strings on to one line separated by a comma.Example might be:
writer.writeline (bob1, bob2, bob3, bob4) Out put might look like Test, Test2, Test3, Test4
I'm tried looking in to formatting of writeline/write, but I didn't get any where with it.
Also if this is possible- I would like to be able to read it just like :
reader.readline (Rbob1, Rbob2, Rbob3, Rbob4) If anyone cold just point me in the right direction, I'm sure I can figure it out - If not... Well I will ask another question.

This is what comes out: "A first occurs in position -1". Everything comes out except the position is always displayed as -1.
Is it possible to change to colour of letters as they are typed.I.e

View 1 RepliesI have to turn strings into Unicode. I thought the best way to do this would be as followed
HTML
For...Next to get the string
For...Next to take each character out of the string
For...Next to display each character in Unicode
The only problem I have is with the separation on each character in the string. I know I have to use a For...Next loop to check each spot in the string. But how would I move on past the first character?
I have this block of code that sets up my sql parameters for a stored proc that does an insert.
Dim sproc As StoredProcedure = New StoredProcedure("UsersInsert2", DataAccessConfiguration)
sproc.AddInput("@ID", SqlDbType.NVarChar, 10, entity.UserId)
sproc.AddInput("@PCode", SqlDbType.SmallInt, entity.PriviledgeCode)
sproc.AddInput("@Pwd", SqlDbType.NVarChar, 10, entity.Password.ToString())

I've tested the stored proc in SSMS and it works.The problem is when I try to call it from the application. it fails. the @@rowcount = -1. I've tried returning an error code from the db... no dice. keeps coming back as -1 what is going to get executed looks like this
sproc = {EXEC UsersInsert2 @ID=ruxtest7, @PCode=0, @Pwd=1234, @Lang=E, @Name=ruxpint, @Notice=1, @CreatedBy=ruxpint}
I've re-used this code several times. only difference being I'm using NVarChar and it's vb.net.

When sending numbers over my server/client, I need to first convert them into strings and pack them together into larger strings, then deconvert them at the opposite end. I need to ensure that they occupy exactly the correct number of spaces in the string - for example I need an integer to use up 4 spaces. So for example, if I had a byte, then 2 integers, I need the first character to contain the byte, characters 2,3,4,5 to contain the first integer and 6,7,8,9 to contain the second integer. Then I can retrieve each number from the string using Mid(Position,Length) and convert it back to a number.I know how to convert bytes using chr and asc, but how would I convert my integers into my string and ensure they occupy the correct number of spaces in the string (and back).All the conversion methods I've looked don't seem to fit the bill. Will I need to write my own function to achieve this?
