PROC_combobox(Dlg%, "",165, 10, 190, 200, 65, &1)
A$="ggggggggg"
SYS "SetDlgItemText", !dlg%,165,A$
Shouldn't gggggggg get printed in the box?
http://www.bbcbasic.co.uk/bbcwin/manual/bbcwing.html#initdialog
I've tried
SYS "SetDlgItemText", !dlg%,165,A$
both before and after
PROC_showdialog(Dlg%)
There's only one dialogue box, so no confusion (lol)
(Tried SYS "SetDlgItemTextA", !dlg%,165,A$ as well)

No. A combobox is a combination of an edit control and a list control. Your code would have worked if you had sent the text to the edit control, but you didn't - you sent it to the combobox itself.
I still don't understand why you're not simply using the code listed in the BB4W Help documentation. That works fine, and you just seem to be making your life harder by trying to reinvent the wheel.
There's an example of the use of that code in the DLGDEMO.BBC program supplied with BB4W (EXAMPLES\WINDOWS folder).
Incidentally, is there some specific reason why you're using a combobox rather than a listbox?
Richard.

I'll use anything.... if it works
I'm just trying to build a simple windows widget which will accept dynamic outputs
PROC_editbox(Dlg%, "Text box",165, 10, 190, 200, 65, &1)
A$="ggggggggg"
SYS "SetDlgItemText",!dlg%,165,A$
Doesn't work either
The DLG example gives outputs only, is there an example with inputs, which dynamically change and then it displays the new outputs
The edit box changes on the final output to the screen but it would be more useful if there was a routine which copied the users input to an output somewhere else on the dialogue box

That's incorrect, it shows both inputs and outputs! It has this code to enter data into the combobox:
Code: SYS "SendDlgItemMessage", !dlg%, 103, CB_ADDSTRING, 0, "Combobox 1"
SYS "SendDlgItemMessage", !dlg%, 103, CB_ADDSTRING, 0, "Combobox 2"
SYS "SendDlgItemMessage", !dlg%, 103, CB_ADDSTRING, 0, "Combobox 3"
SYS "SendDlgItemMessage", !dlg%, 103, CB_ADDSTRING, 0, "Combobox 4"
SYS "SendDlgItemMessage", !dlg%, 103, CB_SETCURSEL, 0, 0
And it has this code to extract data from the combobox:
Code: DIM text% 255
SYS "GetDlgItemText", !dlg%, 103, text%, 255
PRINT "Combobox selection was """$$text%""""
Can't you adapt this code to your requirements?
Richard.

The main reason for this seems to be that you're not using the same variable: you create the dlg box with Dlg% and try to change it with dlg%. These are not the same. They need to be both dlg% or both Dlg%.

I noticed that, but the fact remains that you can't write to a combobox that way, so even if the variables had been the same his original code wouldn't have worked (although the textbox version would).
We badly need that GUILIB library!
