The following from GuiControl does not work:
Code:
PostMessage, 0x185, 0, -1, ListBox1  ; Deselect all items.


The ListBox is not multi-select.

Solution:
Thanks to all involved.

Here is a simpler method.
Code:
Gui, Show
SendInput {PgUp}   ; deselects a control when the text is highlighted after creating and showing it

This does not deselect all items. This selects the first item. How can I select no items?

The message for single-selection list boxes is different.
Code:
PostMessage, 0x186, -1, 0, ListBox1  ; Deselect item.

This did not work for me. Here's my example code:
Code:
Gui, Add, ListBox, vlistbox1 , No|Yes
Gui, Add, Button, , Test
Gui, Show, , Test listbox unselect

ButtonTest:
   PostMessage, 0x186, -1, 0,,listbox1
   Gui,Submit,NoHide
   Return

You added a comma.

You are correct! Without the repeat comma at the end, the code works:
Code:
Gui, Add, ListBox, AltSubmit vlistbox1 , No|Yes
Gui, Add, Button, , Test
Gui, Show, , Test listbox unselect

ButtonTest:
   PostMessage, 0x186, -1, 0,listbox1
   Gui,Submit,NoHide
   Return

How can one use the PostMessage command to work with the listbox's associated variable name?

I could only get the PostMessage command to work with listbox# where '#' is the number of which the listbox was added (listbox1 for the first listbox added, listbox2 for the second, and so on).

To exemplify, here are three different scenarios:

Scenario 1:
Both listboxes will clear.
Code:
Gui, Add, ListBox, AltSubmit vbox_1 , No|Yes
Gui, Add, ListBox, r4 AltSubmit vcrq_impact , 1-Major|2-Significant|3-Minor|4-Standard
Gui, Add, Button, , Test
Gui, Show, , Test listbox unselect

ButtonTest:
   PostMessage, 0x186, -1, 0, listbox1
   PostMessage, 0x186, -1, 0, listbox2
   Gui,Submit,NoHide
   Return


Scenario 2:
Only the second listbox will clear.
Code:
Gui, Add, ListBox, AltSubmit vbox_1 , No|Yes
Gui, Add, ListBox, r4 AltSubmit vcrq_impact , 1-Major|2-Significant|3-Minor|4-Standard
Gui, Add, Button, , Test
Gui, Show, , Test listbox unselect

ButtonTest:
   PostMessage, 0x186, -1, 0, box_1
   PostMessage, 0x186, -1, 0, listbox2
   Gui,Submit,NoHide
   Return


Scenario 3:
No listboxes will clear
Code:
Gui, Add, ListBox, AltSubmit vbox_1 , No|Yes
Gui, Add, ListBox, r4 AltSubmit vcrq_impact , 1-Major|2-Significant|3-Minor|4-Standard
Gui, Add, Button, , Test
Gui, Show, , Test listbox unselect

ButtonTest:
   PostMessage, 0x186, -1, 0, box_1
   PostMessage, 0x186, -1, 0, crq_impact
   Gui,Submit,NoHide
   Return

You may use the window handle (HWND) of each listbox.
Code:
Gui, Add, ListBox, AltSubmit HWNDbox_1 , No|Yes
Gui, Add, ListBox, r4 AltSubmit HWNDcrq_impact , 1-Major|2-Significant|3-Minor|4-Standard
Gui, Add, Button, , Test
Gui, Show, , Test listbox unselect
return
GuiClose:
 ExitApp

ButtonTest:
   PostMessage, 0x186, -1, 0,,ahk_id %box_1%
   PostMessage, 0x186, -1, 0,,ahk_id %crq_impact%
   Gui,Submit,NoHide
   Return

Thank you. This works and is the best solution.
