Drag-n-drop control with-in text-box - How to.

Hello
I am trying to program a Drag and drop questions for my quiz program that uses VB6.
For this data should come from database. Depending on the data I have to dynamically create the controls that hold dropped text.
for example:
"The capital of India is ***** and Population is *****" " is displayed in the question label box. A text control has to be inserted in place of place-holder "*****" dynamically. My intention is to drag and drop objects to the dynamically controlled boxes. Please give some idea as to how to implement creation of text boxes within the context of the question, at run time.

thanks.
