I have programmed a listbox onto the client area. In CreateWindowEx I have set where the list box should be placed on the client and how wide at creation time. But, when the user does something to enter a string, I want to make the listbox accomidate (sp?) to fit another string by making it cyChar longer. I know that I would use MoveWindow to do this sort of thing, but I don't want to fool around with the other three values of the placement/size of the listbox. Is there an easier way to just make the listbox longer without as much risk?
