It depends on which version of CVI you're using. For a listbox, up until version 6.0 the maximum was only around 2-3K, depending on the size of the font. After version 6.0, it should be pretty much unlimited (well, around 2 billion). For a table, the maximum number of cells is supposed to also have been around 2 billion, but there is a problem when highlighting cell ranges beyond the 32k range. This will be fixed in the next version of CVI.
