VB.Net Looping Issues

[wbosw]

I'm trying to take a word (stEAdy) and find the index positions of the uppercase characters(2,3) in the word. I have them stored in an array (positionarray) . Then I reverse the word and set all characters to lowercase. I've done that. Now, I want to take the reversed word (ydaets) and make the index positions from the array(2,3) uppercase for the reversed word, so that it will read (ydAEts). Below I'm looping thur the array incorrectly. I'm only able to get the first index position set. Any suggestions on setting up the loop correctly?

Thanks,
Wbosw

 'loop thur the position array, giving the position of the capital letters in each word
            For Each Charposition As Byte In PositionArray

                'set byte variable for For loop
                Dim j As Byte

                'declare Char variable to hold the actual characters
                Dim char2 As Char

                'set finalstring to nothing
                finalString = " "

                'loop thur each word to see which positions are equal to the positions in the array
                For j = 0 To LowerRevText.Length - 1

                    char2 = LowerRevText.Chars(j)

                    'if the positions are equal then change the character to Uppercase
                    If Charposition = j Then

                        'change the position to uppercase
                        CapChar = Char.ToUpper(char2)

	         'set char2 equal to CapChar
                        char2 = CapChar

                    End If

                    CapRevText += char2

                Next

                'add a space between the words
                finalString += CapRevText + " "

                'set variable = to nothing
                CapRevText = " "

            Next

I'm unclear on what situation you want to happen based on your example

Situation 1:
You want to make "tReE" be "eErT"


Situation 2:
You want to make "tReE" be "EeRt"


Situation 2 is just a reverse of the original string so I think you want situation 1.
if you have the positions in an int[] (that would be {0,3} for this example)
You would do something like this:

//ReverseLowerCase = original string reversed and converted to lowercase
//ReverseUpperCase = original string reversed and converted to uppercase
for(int i =0; i<myPosArray.Length;i++)
{
   ReverseLowerCase[i]= ReverseUpperCase[i];
}

You will need to make adjustments to fit vb

My situation is like #1:

So I want to turn ( tReEGHp) into ( pHgEERt ) that would be positions 1,3,4,5.

would ReverseLowerCas e[i]= ReverseUpperCas e[i]; work in this situation, because it's on odd number of positions. if so, thanks in advance

Say you had:
"TreEs"
Then ReverseLowerCas e ="seert"
and ReverseUpperCas e ="SEERT"
So if you knew you wanted index 0, 3

Then setting ReverseLowerCas e[0]=ReverseUpperCa se[0]
would make ReverseLowerCas e="Seert";
And setting ReverseLowerCas e[3]=ReverseUpperCa se[3]
would make ReverseLowerCas e="SeeRt";

Thanks again Plater, you've been a great help.
