Looking for people who could help me with a text search

Looking for people who could help me with a text search.
Code that I want to make work perfectly, but it finds only one word.

So far I have only this code.

Code:

---

  Dim a As String
        Dim b As String
        a = mu1.Text
        b = InStr(mu2.Text, a)
        If b Then
            mu2.Focus()
            mu2.SelectionStart = b - 1
            mu2.SelectionLength = Len(a)
        Else
            MsgBox("No text Found!")
        End If

---

I need a code which is found not only a word but also all related to my fit the found word.

To help you understand what I really need to give the image, you will see that we have created code that I include only one word but even all the found words in accordance with the keywords I entered.

So I need a code that after entering some word keyword could find all the other related keywords with my summary of the word to fit.

Use textbox1 and multi textBox2 and button.
So I want to know how do I do it?

As you can see it finds only one word.
But this is not what I need.
I need it all found and keywords to highlight a full row and not just the part.

Considering that you're using a textbox, you cannot highlight more than one word. It's just like using the find feature in internet explorer(control + f). It will give you the number of matches, just not highlight every match. In order to highlight the next match, you click the next/previous button.

And this right here: "keywords to highlight a full row and not just the part" are you wanting to select the line that contains the keyword? I'm not quite following that statement, could you elaborate a bit?

This is exactly what I want.
I wanna select a full line and hightlight it when you click item in textbox but not just a part of text.

This is how it should look like.
A click on the text should not select the part of the text.
it should choose a full line just on one click but not on double click as is usually.

This is all what i want.

You want to hilight all lines that contain the text u have entered?

An alternative is to use a RTB and colour the text that matches (similar to the IE yellow selection) and then a simple select full line of the 1st item if required.
