Sounds like a good start. But, I would suggest that you think of it
as taking a list view dialog and combining it with your routine. It's
a subtle point, but I think you will have less trouble trying to add a
routine to a list view dialog than you will have trying to force a
routine to use a dialog.

Why not? ;-) Post a little more information on what you routine that
reads the column names from DB2 looks like.
Here is a rough sketch of an approach.
::method initDialog
-- Get a reference to the list view.
list = self~newListView(IDC_LISTVIEW)
list~addExtendedStyle("FULLROWSELECT GRIDLINES CHECKBOXES HEADERDRAGDROP")
-- Call your routine to get the column names, but I don't have any
idea what you routine
-- looks like so it is hard to do this part.
col1Name = getDB2columnName(1)
list~insertColumn(0, col1Name, 80)
col2Name = getDB2columnName(2)
list~insertColumn(1, col2Name, 80)
col3Name = getDB2columnName(3)
list~insertColumn(2, col3Name, 70)
do i = 1 to 200
data = getDB2rowData(i)
list~addRow(i, data~col1, data~col2, data~col3)
end
There is no reason you can not call your routine from the dialog code.
The above code's idea is this: call your routine to get the column
names for a table in DB2 that has 3 columns. Set the column names in
the list view to those 3 column names. Call your routine to get the
row data for 200 rows and fill in the list view with that data.
The other approach would be to assemble your data first using your DB2
routines and pass it into the dialog. But, the approach above would
be better I think.
As is usual in trying to give help, the more information you provide
the better help you will get. Without knowing anything about what
your existing routines are like, it is difficult to give you back
specifics.
