Dialog question

[ilcaa]

i can initialize a control before the ShowDialog(), c3Che = 1
but
in a Dlg Procedure, i cannot change the state of the checkbox with c3Che = 0

Code:

Copy      Help

str c3Che e4 b5But

c3Che = 1 ;; initializes checkbox with a check

int hDlg=ShowDialog("" &sub.DlgProc &controls 0 1 1)

___________________________________________________
sel wParam
    case IDOK
    case IDCANCEL
    case 5         ;;button
        c3Che = 0  ;; doesnt work 

can you explain why it doesnt work in the sub procedure?  it recognizes that 3 is a control via the Case... does it not recognize the str variable?  whats the better option for changing state of controls in sub-procedure. thanks

var c3Che is not known inside the dialog procedure
you can however use it by adding the v attribute to #sub DlgProc and calling DT_GetControls later inside the dialog.Then can use DT_SetControl or DT_SetControls to change it's value

example

Function Dialog9

Code:

Copy      Help

str dd=
;BEGIN DIALOG
;0 "" 0x90C80AC8 0x0 0 0 224 136 "Dialog" "4"
;3 Button 0x54012003 0x0 16 48 48 10 "Check"
;4 Edit 0x54030080 0x200 72 48 96 12 ""
;5 Button 0x54032000 0x0 172 48 48 14 "Button"
;1 Button 0x54030001 0x4 116 116 48 14 "OK"
;2 Button 0x54030000 0x4 168 116 48 14 "Cancel"
;END DIALOG
;DIALOG EDITOR: "" 0x2040A00 "*" "" "" ""

str controls = "3 4"
str c3Che e4
c3Che=1
if(!ShowDialog(dd &sub.DlgProc &controls)) ret


#sub DlgProc v;; must have v attribute here to use Option1
function# hDlg message wParam lParam

sel message
,case WM_INITDIALOG
,case WM_DESTROY
,case WM_COMMAND goto messages2
ret
;messages2
sel wParam
,case IDOK
,case IDCANCEL
,case 5 ;;Button
,;;Option1 using v attribute and calling DT_GETControls and DT_SetControl
,DT_GetControls(hDlg)
,c3Che=0
,DT_SetControl(hDlg 3 c3Che)

ret 1

even simpler without using v attribute and DT_GetControls
Function Dialog9

Code:

str dd=
;BEGIN DIALOG
;0 "" 0x90C80AC8 0x0 0 0 224 136 "Dialog" "4"

;4 Edit 0x54030080 0x200 72 48 96 12 ""
;5 Button 0x54032000 0x0 172 48 48 14 "Button"
;1 Button 0x54030001 0x4 116 116 48 14 "OK"
;2 Button 0x54030000 0x4 168 116 48 14 "Cancel"
;END DIALOG
;DIALOG EDITOR: "" 0x2040A00 "*" "" "" ""

str controls = "3 4"
str c3Che e4
c3Che=1
if(!ShowDialog(dd &sub.DlgProc &controls)) ret


#sub DlgProc
function# hDlg message wParam lParam

sel message
,case WM_INITDIALOG
,case WM_DESTROY
,case WM_COMMAND goto messages2
ret
;messages2
sel wParam
,case IDOK
,case IDCANCEL
,case 5 ;;Button
,DT_SetControl(hDlg 3 "0")

ret 1
