Posts: 174                I have a Listbox that loads in various data from an 
SQL database based on user selections.

After loading a number of different views the program crashes. I couldn't 
figure out why until recently. The problem is that you're only allowed 64 
columns - which inherently isn't a problem as I never display that many at one 
time.

The problem exists in that the columns don't get deleted when I load a new 
report.

(Note* lb is a listbox)
lb.DeleteAllRows
lb.ColumnCount = 0
For i as integer = 1 to rs.FieldCount
  dim n as string = rs.IdxField(i).Name
  lb.addColumn(n,n,"")
Next


Because I can't do lb.DeleteAllColumns i just set the ColumnCount to 0 to get 
rid of them, the problem is that eventually the addColumn method will be called 
enough times to exceed the 64 column limit as the columns aren't actually 
deleted.


I'm thinking the best way to work around this is to just start the listbox off 
with 64 columns, all with 0 for a width. Then don't call addColumn, and just 
change the columns width and other properties when I need it.

Comments? Suggestions?
