Ok this should be an easy one


When first looking at a DropDownList the selection is empty
So I select an entry using the following:

GuiControl, 1:ChooseString, DropDownListID, % "DDL Entry 1"

Now the entry with the name "DDL Entry 1" is selected


But how do I clear the DropDownList selection, back to empty like it was when the script first started?
I tried:

GuiControl, 1:Choose, DropDownListID, 0

And:

GuiControl, 1:ChooseString, DropDownListID, % ""

But neither work



SOLUTION:
Setup the DropDownList with a hwnd as follows:

Gui, Add, DropDownList, hwndDDL_ID, Item1|Item2|Item3

Then to clear it use:

SendMessage, 0x014E, -1, 0,, ahk_id %DDL_ID%

isn't it something like

GuiControl,, DropDownListID, |

Try that.

Are you sure that doesnt just clear the list?
Rather than keep the list but select nothing on it?

Anyway I'll report back

Edit:
Unfortinately I was right
It didnt select anything
But that was because there wasnt anything to select
It cleared the list rather than selecting nothing

But this could be a possible work around
To clear the list then repopulate it...

It works. Don't worry about posting back.

It works. Don't worry about posting back.

Actually it didnt, see my edit above

[Superfraggle]

PostMessage, 0x185, 0, -1, ListBox1

Have you tried that ?

[Mustang]

Ok the work around worked:

GuiControl, 1:, DropDownListID, |
GuiControl, 1:, DropDownListID, DLL Entry 1|DLL Entry 2|DLL Entry 3

But can anyone tell me the propper way to do this?

[Mustang]

PostMessage, 0x185, 0, -1, ListBox1

Have you tried that ?

Yes I already did, but didnt work
Apparently it is only for multiple-selection list boxs so not surprising there

Also tested

GuiControl, 1:Choose, DropDownListID, |

But that didnt work either

[trik]

WOOT :!: :!:

Gui, Add, DropDownList, W100 H50 vDLL, 1|2
Gui, Add, Button, W100 gSelect, Select 1
Gui, Show
Return

Select:
ControlSend, ComboBox1, {Down}

[Superfraggle]

If it's a Combobox the correct message is

Gui +LastFound
PostMessage, 0x014E, -1, 0, ComboBox1

tested and working ok.

[Mustang]

ComboBox what?
Its a DropDownList

[Mustang]

Thanks for the effort guys, but the functionallity I was after goes more like this:

Gui, Add, DropDownList, W100 H50 vDropDownListID, DLL Entry 1||DLL Entry 2|DLL Entry 3
Gui, Add, Button, W100 gSelect, Select 1
Gui, Show
Return

Select:
GuiControl, 1:, DropDownListID, | 
GuiControl, 1:, DropDownListID, DLL Entry 1|DLL Entry 2|DLL Entry 3

But without having to use

GuiControl, 1:, DropDownListID, | 
GuiControl, 1:, DropDownListID, DLL Entry 1|DLL Entry 2|DLL Entry 3

IMO Logically the correct syntax should be:

GuiControl, 1:Choose, DropDownListID, 0

Or:

GuiControl, 1:Choose, DropDownListID, -1

But neither are working

[Superfraggle]

I know it's a drop down list, but as far as the system calls it it is a ComboBox.

The example I posted works, Try it.....

heres the full code i used to test it

gui,add,[color=red]dropdownlist[/color], vban hwndhwnd,a|b|c|d|e|f
gui,show, ,Bleah
sleep 5000
Gui +LastFound
PostMessage, 0x014E, -1, 0, ComboBox1
sleep,5000
exitapp

Nice one Superfraggle
The reason it wasnt working for me was because I didnt use:

Gui, +LastFound

Then when I did it still wasnt working because I forgot to change to:

Gui, 2:+LastFound

TY

Edit:
I decided to use SendMessage instead to make sure it gets cleared before using:

Gui, Show

[Superfraggle]

lol the other way of doing it would be

gui,add,dropdownlist,  hwnd[color=red]hwndvar[/color],a|b|c|d|e|f
gui,show, ,Bleah
sleep 5000
Gui +LastFound
PostMessage, 0x014E, -1, 0,,ahk_id %hwndvar%
sleep,5000
exitapp

That's probably the better way of doing it if you use more than one ddl.
