Listbox selection

[ckoehn]

Is it possible to programaticaly remove a selection on an item in a listbox control?  There is a SETSELECTED but no DESELECTITEM.

Thanks

Use the SETSELECTED command with a position  of -1

Thanks Larry.  I appreciate your help.

Sorry Larry.  Setting it to -1 doesn't work.  Here is my list settings.  It is a multi-selection list box.

I used: SETSELECTED win,2,-1

CONTROL win,@LISTBOX,"",370,tHeight*2,180,60,@TABSTOP|@CTLISTEXTENDED|@VSCROLL|@CTLISTNOTIFY|@CTLISTSORT,2

Went back to the SDk and it states that what I told you to do will not work when you have the multiselect flag set.

The only thing I would know to do is delete all the items in the listbox and then reload it.

I've done it before but right now I don't know where a copy of the program I did it in is located.

Use this to clear out your listbox:

Code Select Expand

CONST LB_RESETCONTENT = 0x184
SENDMESSAGE win,LB_RESETCONTENT,0,0,2
then reload it

An application sends an LB_SETSEL message to select a string in a multiple-selection list box

Code Select Expand

SendMessage(d1, LB_SETSEL, FALSE, -1, listbox_id)
Should deselect all items. Include windows.inc or windowssdk.inc.

I missed that one, Sapero.  As always you come through!
