Did

The /did command allows you to modify the values of controls in a dialog, eg. changing the text in an edit control, or setting focus to a button, or deleting lines in a listbox.

 /did -ftebvhnmcukradiogjsl name id [n] [text | filename]
 Where name identifies the dialog and id is the id number of the control you want to modify.

 -f	set focus on id
 -t	set id as default button
 -e	enable id
 -b	disable id
 -v	make id visible
 -h	hide id
 -n	enables editbox
 -m	disables editbox
 -c	check checkbox/radiobutton list/combo line
 -u	uncheck checkbox/radiobutton list/combo line
 -k	works with -cu, keeps other selections in a listbox
 -s	checks the checkbox of an item in a listcb control
 -l	unchecks the checkbox of an item in a listcb control
 -r	clear all text in id
 -a	add line of text to end
 -d	delete Nth line
 -i	insert text at Nth line
 -o	overwrite Nth line with text
 -g	set a new icon/bmp to an icon control /did -g name id [n] filename
 -z	resets the width of horizontal scrollbar in listbox
 -j	resets the edited setting in an editbox

If you want to modify several controls at the same time, you can specify multiple id numbers separated by commas, eg. /did -b name 2,12-16,20 etc.

You can select a range of text in an editbox using /did -c name id [n] [start [end]]. This selects line N in editbox, and sets selection to specified range of characters.

You can mark a 3state checkbox as indeterminate by specifying both -cu switches.

You can access the edit control in a combobox by using 0 as the N value.

To change the range of a scrollbar control, you can use /did -z name id [min max].
