Let's say I have regular string called tempstring, and I want to change a specific item in that string. Like if tempstring = ";1;2;3" and I want to change the "2" to "Baboon." Here's my best solution on how to do it:
vb
Tempstring = ";1;2;3"
'Datasplit tempstring
Dim datasplit As String() = Tempstring.Split(New Char() {";"c})
[Code]....
This works, however, it feels a little heavy. Is there an easier way to do this? Perhaps a way to directly replace datasplits without readding them all to another string one by one using a loop?

View 5 RepliesThe file reads in parameters and two of the parameters used to be in Date Format YYYYMMDD but will now permanently be in format YYYY-MM-DD. This change, I believe, is stopping the import of the file from working. I would like to replace the new format YYYY-MM-DD back to YYYYMMDD in the code. If possible I'd also like to see some output so I know that the old format has been replaced with the new format. The code is below. I added the two rows with .replace code in green in expecting that to be enough but it is still not working.

View 4 RepliesProblem: Your task is to take input from the user in string and give the following options to the user in a menu.
1- Find a String
2- Create sub-string
3- Erase a portion of a sting
4- Replace a word in the string
5- Count number of words and characters in the string without spaces.
6- Capitalize first character of each new sentence and convert the rest
of the characters to lower case.
7- Sort all the words in alphabetical order. (Use Bubble sort algorithm to perform sorting).
To perform all the above mentioned tasks you can only use pointers. Create a function to perform every task.

MyArray (2) = MyArray (4) = MyArray (7) = MyArray (10) = 18
MyArray (0) = MyArray (12) = 12
