Passing a value to dialog through hooked toolbar

[ssimop]

A routine (B4SES) call a toolbar with :

mac "MyClock-3" hDlg

Toolbar MyClock-3

Code:

Copy      Help

;/hook MyClockHookProc

where
Function MyClockHookProc

Code:

Copy      Help

;/
function# hWnd message wParam lParam

sel message
,case WM_INITDIALOG
,hid id(9999 hWnd)
;,ShowDialog("MyStopWDialog" &MyStopWDialog 0 hWnd 1 WS_CHILD WS_POPUP|WS_CAPTION|WS_SYSMENU 0 0 3)
,ShowDialog("DateTimeShow" &DateTimeShow 0 hWnd 1 WS_CHILD WS_POPUP|WS_CAPTION|WS_SYSMENU 0 0 4)
,;the 4 adds 4 pixels at the top where you ca right click or drag the toolbar
,case WM_DESTROY
,,

I want to pass a value (parameter) from "B4SES" to "DateTimeShow". I understand it can be done easily by initiating a global variable in "B4SES". I wonder whether there exists another more elegant way to do it. If I used a message

SendMessage(dialogHandle WM_APP+1 0 &x)

I wonder whether it should be sent directly to "DateTimeShow" or rather through "MyClockHookProc".

Any advice is mostly welcome. Many thanks in advance.

send directly.
