hi,
2 questions
For a listview, I want the user to choose the columns for a specified output though all the columns will be filled with data , i want to display only those columns which the user selects(Like we have it in windows explorer). Currently I make the width of the hidden column as - 0 but that the user can just keep his mouse on the header and drag to see the hidden column. How do I actually hide it???

Second question:

I have just recently find out that one cannot set the interval time of a timer for than 65000 millisecs that is apporx a minute. How do I set the interval of a timer for more than a minute say 3 minutes?

Thanks.
