How can I select and highlight a listbox entry in my script before displaying the initial screen?

2. This is how I do it with one of my scripts

/***************************************************************
 Update the progress list to show what's happening              
***************************************************************/ 
insert_progress_list:

USE ARG string

guisendmsg('progress_list', 'ADDSTRING', , string)
guigetmsg('CLEAR')

/* Make sure we set focus on the current line in the
   results, so the user doesn't have to "scroll" all the time */
count = count + 1
progress_list = count
guisetctlvalue('progress_list')

RETURN 0

This presupposes that you have defined your list with

LIST 14, 62, 504, 246, NOTIFY|REALHEIGHT|KEYS|BORDER|VSCROLL|TABSTOP, INDEX, progress_list

By doing the guisetctlvalue above, you're saying "highlight the count'th row of the the list". If you don't have the index option, then you need to know the contents of the row (and for my progress lists, that's highly unlikely)

Thanks, this solved my problem.

Is it possible to access the "text" in a listbox after defining it with the INDEX option?

5. How do you mean ?

Where has the data for the listbox come from ?

I'm using the following statements to load the listbox (Listfiles).

error = GuiSendMsg("Listfiles", "DIR",, "!*.txt")
error = GuiSendMsg("Listfiles", "DIR",, "~*.txt")
error = GuiSendMsg("Listfiles", "InsertString",,"~None")

error = guisetctlplacement('Listfiles')

Thanks,

George

Yes, but you need to know the line number you want (where the first line is 1, the second line is 2, etc). Send the GETLBTEXT message with GuiSendMsg, and pass the line number, and the quoted name of a variable where you want the text returned.

/* Get the first line */
linenum = 1
guisendmsg("Listfiles", "GETLBTEXT", linenum, "MYVARIABLE")
SAY myvariable
