I got a workaround for the effect I wanted. The steps are as below:
I created a regular Text Object, a BB Code Text Object and a text variable that is going to change.
I used the text object to construct the string that I will use in the BB code text that supports BBcode.
This is how I constructed the text input and I included the text variable inside of it: "
" &kidname & "
[/color][/size]"
Now I will consider that the variable is a name so the output of the string is going to be a BBCode with the name ziad inside of it: "
Ziad
[/color][/size]"
So I take all this string and I assign it within a BBcode text like this:
"Hello, My name is "& TextBox.Text &"." and it was a magic moment where my text variable is beautifully colorful within my text..
Hope this could help...
Cheers
