You don't say explicitly but I'm assuming you're using MapBasic.
Having opened your table (you'll have the name if you use your FileOpenDLG)
you need to use TableInfo(myTabName, TAB_INFO_NCOLS) to get the number of
columns.
Then loop each column (infuriatingly you have to build a string so that you
go "COL1", "COL2" etc rather than simply 1,2,3). Use ColumnInfo statements
(eg ColumnInfo(myTabName, "COL1", COL_INFO_NAME)) to build up an array - you
can put the array straight into a dialog box list control.
Eg
Control ListBox
ID 1
Calling MyListHandler
Title from variable MyArray
Into iMyListchoice
>From the user choice on the list use code in the handler to store the return
value in a string for use elsewhere in your program.

Subject: MI-L MI-selecting Columnnames in a table?
Dear List,
I need some help implementing a routine/dialog which allows the user to
select a specific
column in the opened table.
That is the way it should happen:
After starting an Application a FileOpenDlg is displayed allowing the user
to open a MI-table.
Beyond this point I would like to display a Dialog or something else which
shows the user:
1. all the columnnames in the table he opened.
2. allows him/her to select one column.
The data in this selected column should be used in a variable for the
following routines.
I know the easiest way should be to use static Table definitions but this is
not possible!
Any help would be greatly appreciated.
Mit freundlichen Gr��en
