Display New Item in Drop Down List

[dunnerca]

I have a Gui which contains a drop-down list populated from reading a textfile of client names.

Code: Select all

Gui, 1:Add, DropDownList, x120 y230 w300 vClient gDDLChoice, %ClientList%

This works fine. One of the items on the DDL is "Add new client" which triggers "DDLChoice" and opens a new Gui with a text box to add the new client's name. I've put the code below. After clicking the button on Gui 2, the script will append the new client name to the end of the text file (F1). Then I have AddNewClient re-read the text file into the ClientList array, sort it, and re-open the Gui 1: (which contains the DDL of client names).

My problem is that I can't figure out how to have the ClientList updated in the DDL when Gui 1: is re-shown.

Code: Select all

DDLChoice:
	Gui, 1:Submit
	if (Client="Add new client"){
		Gui, 2:Add, Text,,Client Name:
		Gui, 2:Add, Edit, w200 vNewClient
		Gui, 2:Add, Button,gAddNewClient,Add
		Gui, 2:Show, w300 h300
	}
	else
		Gui, 1:Show
	Return
	
AddNewClient:
	Gui, 2:Submit
	FileAppend, %NewClient%`r`n,%F1%

	Loop, Read, %F1%
		ClientList .= A_LoopReadLine "|"
	Sort, ClientList
	Gui, 1:show
	Return

Any help would be most appreciated. I've scoured the forum with no result that will let me do this.

GuiControl may work.

Thanks for the tip. I've tried GuiControl but there doesn't seem to be an option to "redraw" the DDL. I thought of deleting the DDL and re-adding it but the "delete" option isn't available. Perhaps there's some way of updating the DDL through GuiControl that I haven't picked up on?

Code: Select all

str1 = Black|White|Red|Green|Blue
str2 = Orange|Black|White|Red|Green|Blue
Gui, Font, s10
Gui, Add, DropDownList, w250 vsel, %str1%
Gui, Show,, Test
F3::
GuiControl,, sel, |%str2%
MsgBox, 64, Status, Updated!
Return

Thanks for your reply, again. My script is using a g-label where the new client is added. Your example doesn't use this so I'm assuming that the problem is that my new list is being created within my "AddNewClient" subroutine area?

Add a GuiControl command to your script. Post a revision if it does not work. The GuiControl command modifies the DDL. To learn about it, click the command in the posted script. You could also test the script that I posted, to see if that script works. You can report here about whether it does work. Here is another example of GuiControl. viewtopic.php?p=440597#p440597

This code above is what I changed from the original post, using the GuiControl command you suggested. I have verified that the new client name is added to the text file (F1). Thanks for your persistence, @mikeyww .
