Here it is:
I want the user to type in as string like (I go to VB school) into a textbox. Each time the user clicks a command button, it will capture the location of the space and the string before space. e.g. when the user click a command button for first time, it shows location of space AND character which is "I", when the user click a command button for second time, it shows the location of the space again, and "go".....etc.
It is pretty straight forward, but I would like to know the logic more than anything else.
