Let all editbox support drag and drop files and texts

[Kevin]

It's probably best in this situation to switch to a multiline edit control
then enter wont close dialog.

But for future reference to prevent dialog from closing when enter key is pressed
find IDOK and add code

Code:

Copy      Help

,ifk(Y)          ;; Enter
,,ret 0

so it looks like this

Code:

Copy      Help

,case IDOK
,ifk(Y)          ;; Enter
,,ret 0

for the text erase problem  change

Code:

Copy      Help

,,s.setwintext(di.hwndTarget)

to

Code:

Copy      Help

,,s.setsel(0 di.hwndTarget)

for multiline edit control 

use this code

Code:

Copy      Help

str dd=
;BEGIN DIALOG
;0 "" 0x90C80AC8 0x8 0 0 352 220 "Dialog" "4"

;END DIALOG
;DIALOG EDITOR: "" 0x2040A00 "*" "" "" ""

str controls = "3"
str e3
if(!ShowDialog(dd &sub.DlgProc &controls)) ret

out e3
