how to use multi list box to display contents in a 2D variant array

[MViControl]

Hi all,

When I use NI data connectivity toolkit to search database , I plan to use a multi list box (as a table) to display the seach database results, but I found the default output of the earch is a 2D variant array. How can I display the contents in a multi list box?

Thanks

The variant can be coerced to a string, or other data type if known. Data types can be pulled from the database if absolutely required.

You can convert variant to string and display the result in the MCL.

I have a small utility VI to help...

If you have a valid connection reference, use the DB Toolkit vi located at:

vi.lib\addons\database\Auxilliary.llb\DB Tools Select All Data.vi

This vi returns a 2D array of string that you can write to the ItemNames property of a MCL or the Values of a table control.

If you have a recordset reference, you can use the sub-vi inside the one above called

vi.lib\addons\database\Auxilliary.llb\DB Tools Fetch Table Data.vi

No special coding or libraries required. You can use the VIs NI gives you (they are not on the palette though )
