I'm not sure of the code that will allow you to drag the textbox to desired height/width...but what you could do is...have two text boxes and in their Text1/Text2_Change Events place this code:
Code:
'Under Text1_Change 
Text3.Width = Text1.Text
'Under Text2_Change
Text3.Height = Text2.Text
You might want to restrict the textboxes to numeric characters only.
