Simple excel query

Question

Hi,
I am connecting to an excel spreadsheet. I have no problems connecting but when I query it my app. goes into an infinate loop.
When coding:
rs = stmt.executeQuery(query);
while(rs.next()) {
// display my results
I get valid results fine but after my data has run out the rs.next() still returns true. I only have 25 rows in my spreadsheet but when viewing the sheet in excel all the rows after the 25th are blank. Is there a way in excel delete all the rows after 25th?
I hope someone knows what I'm trying to say and can give me the simple solution I'm sure I'm missing!
Much appreciated,
Vaughne

What I would do is simply check if an entire row in your result set is empty. If so you keep track of that with a counter.
As you can see sometimes there can be empty lines for formating an excel sheet. I would pre-define a number which tell how much rows maybe
empty after eachother. For example 10. Once exeeded this number you stop your loop.
After that to delete the last lines simply do current row number - 10
the predefined number (10) and delete does.
I see you display your data emediatelly.
This has to be changed. And you need to put this into a vector.
This way you can operate on deleting some rows if you want.
Afterwards just loop over the vector and display your results.
Now how does this work.
Cell 1 Cell2 Cell3
1 2 3
5 7 7
5 1 9
