Hi Please help...

I am using the widget filesel in order to select files to open. the
example in the help only allows you to pick a single file. i want to
pick multiple files. when i click on multiple files, however, the
event handler only picks the first which is selected...how do I return
all those files which are selected in the event handler?

thanks in advance

russ

As pointed out in the on-line help, the event structure
only contains the first of the multiple selected files in
the VALUE field. If you want *all* of the selected files, you
have to use the GET_VALUE keyword to get them:

Widget_Control, event.id, Get_Value=allSelectedFiles

Cheers,

David

Hi Russ,

If u r problem is only select multiple files, then use
DIALOG_PICKFILE function with MULTIPLE_FILES keyword set to 1 (
/MULTIPLE_FILES ), then it allows u to select multiple files and
returns an array of string, which is a string array of all file
names.Then u can pass this variable to event procedures.

Cheers,
Vijay.K
