LISTVIEW SET COLUMN -2 and -1

[Mike Doty]

'LISTVIEW FIT CONTEXT and LISTVIEW SET COLUMN adjust
'the columns widths after the listview is filled. Tried using
'LiSTVIEW SET COLUMN with -1 and -2 options and get no column widths.

FOR col = 1 TO ColumnCount   'fit columns
    LISTVIEW FIT CONTENT hDlg, %LISTVIEW, col
    LISTVIEW FIT HEADER  hDlg, %LISTVIEW, col
    'LISTVIEW SET COLUMN hDlg, %LISTVIEW, col&, -2
  NEXT

The LISTVIEW SET COLUMN statment using a -1 or -2 is working for me

#COMPILE EXE
#DIM ALL

FUNCTION PBMAIN () AS LONG
  LOCAL hDlg  AS LONG
  LOCAL i     AS LONG
  LOCAL j     AS LONG

  DIALOG NEW 0, "Dialog1", , , 300, 125, TO hDlg
  CONTROL ADD LISTVIEW, hDlg, 1000, "", 5, 18, 290, 75
  CONTROL ADD BUTTON, hDlg, 1001, "Use -1", 1 ,1, 50, 14
  CONTROL ADD BUTTON, hDlg, 1002, "Use -2", 60 ,1, 50, 14

  FOR i= 1 TO 4
    LISTVIEW INSERT COLUMN hDlg, 1000, i, "Column #"+FORMAT$(i), 100, 0
  NEXT i

  FOR i=1 TO 4
    LISTVIEW INSERT ITEM hDlg, 1000, i, 0, "Item #1"
    FOR j = 2 TO 4
      LISTVIEW SET TEXT    hDlg, 1000, i, j, "Item #"+FORMAT$(j)
    NEXT j
  NEXT i

  DIALOG SHOW MODAL hDlg, CALL DlgProc
END FUNCTION

CALLBACK FUNCTION DlgProc
  LOCAL i AS LONG

  SELECT CASE AS LONG CB.MSG
    CASE %WM_COMMAND
      SELECT CASE AS LONG CB.CTL
        CASE 1001
          FOR i=1 TO 4
            LISTVIEW SET COLUMN CB.HNDL, 1000, i, -1
          NEXT i
        CASE 1002
          FOR i=1 TO 4
            LISTVIEW SET COLUMN CB.HNDL, 1000, i, -2
          NEXT i
      END SELECT

  END SELECT
END FUNCTION

Both -1 and -2 wipeout the data inside the listview using XP SP3 using your code.

[Mike Doty]

Vista Home Premium and the results also get erased within the listview.

Hi Mike,

That would be because I am using a beta copy of 9.01. I tested this with 9.0 and you are correct the data items are being deleted.

The free update to 9.01 will be available soon and no I do not know the date of the release (sorry).

LISTVIEW SET COLUMN -2 and -1

I agree with Mike it does not work.
Running your posted code here deletes each column using either the -1 or -2 button.

LISTVIEW SET COLUMN CB.HNDL, 1000, 3, -1

Deletes column 3

Ooooh, oooooh.....Mr. Kot-TairRRRRrrreee
I guess now is a good time for Feature requests, and possible "Bug" fixes (not fake bugs, but bugs that proved to be real?) kinda thing????

By the way...how do you sign up to become a beta-tester? (Pb is sooooo good that I actually find myself wanting to beta-test instead of leaving it up to people that miss "That lil something", that I find in most products )

Mike, I just tried Scott's code too with Vista Ultimate, and it wiped everything out. (Both for -1 and -2)

Gut Instinct is telling me I am onto something here (without even looking at how a ListView works), but have to ask "Why -2?" (like I said "Instinct" and just going by odd posts in my head) as -1 should hide a column (but thinking -2 has something to do with DDT vs SDK ???

Anyways I could be WAYYYY off here cause a 5 second lookup of "ListView SET" led me to a new compiler keyword.

Hmmm back to the docs
