I am trying to display the contents of a database using listview. I am=0D
looping through the database to populate the list box using this little=0D
snippette: =0D
=0D
count =3D addLVItem(myLV,1,db_key) =0D
count =3D addLVItem(myLV,2,db_data) =0D
Instead of getting the key in column1 and the data in column2 it is putti=
ng=0D
the the first key in column one with it's data under it and then it puts =
the=0D
second key in the first column with it's data under that. Nothing is goin=
g=0D
into column 2. What am I doing wrong?=20

I really should rename addLVItem() to something like addLVRow() because that's
what it does. It adds an entire row of listview column data items in one go.
You need to give it all the column values as a sequence in the last parameter.
The second parameter is meant to be a handle to an icon.
So try this instead...
count = addLVItem(myLV, 0, {db_key, db_data} )
This assumes that you have created or set up the listview with the correct
number of columns.

Well the first thing is to work out how you got 3 columns in the first place.
Can we see your create() call for it? Are you using insertLVColumn() anywhere? If
you only need two columns your create() call could look like this ...
myLV = create(ListView, {"Key", "Data"}, ... ,LVS_REPORT)
And if you know how wide you want them at the outset you could create it that
way too...
myLV = create(ListView, {{"Key",100,0}, {"Data",400,0}}, ... ,LVS_REPORT)
will create two columns, 100 and 400 pixels wide respectively.
