I want to insert a word inside an existing word? Both are Strings.
For example:
Given String word:
HELLO SAMPLE SENTENCE
i want to insert the word I AM A so my output would be:
HELLO I AM A SAMPLE SENTENCE
i am inserting here basing on the word SAMPLE. So the insertion starts before the word SAMPLE. is this possible?
Based on the description of your logic (which isn't much to go on), I would use:
Dim input As String = "HELLO SAMPLE SENTENCE"
Dim iSample As Integer = input.IndexOf("SAMPLE")
Dim output As String = input.Insert(iSample, "I AM A ")
This uses the BCL function String.Insert, which simply inserts a string into another string at a particular position.
6, but use input.IndexOf("SAMPLE") instead
Create a function like this:
Function InsertBefore(sentence As String, find As String, textToInsert As String
Return sentence.Replace(find, textToInsert+Find)
End Function
And call it like this:
sentence = InsertBefore("HELLO SAMPLE SENTENCE", " SAMPLE ", "I AM A")
If I remember correctly, you can use the String.split() function on your string.
See DotNetPerls' page on Split here.
You can split the string into an array, then insert the line you want into the array, then join them back together using String.Join() (thanks Monty, I don't use Visual Basic that frequently anymore, I forgot that :)).
Hope this help :)
