Hi To All ,

You can use GetControlHandle


Ex:GetControlHandle( 'br_grid', cActiveJan )

hi,

You can use GetControlHandle
Ex:GetControlHandle( 'br_grid', cActiveJan )

you need a "Name" of Control which is a Combobox.

a Combobox have 2 x "Parts" : TEXTBOX + LISTBOX

but i only want the Handle of Listbox "Part" which have "no Name" ...

hi,

got more Information

when CBN_DROPDOWN notification code is send Listbox Part will open
Then use FindWindowEx() to get the handle of the control ...

this is one Way

other Way COMBOBOXINFO structure (winuser.h)
https://docs.microsoft.com/de-de/window ... mboboxinfo

hwndCombo Handle to the combo box.
hwndItem Handle to the edit box.
hwndList Handle to the drop-down list.

to get Information use GetComboBoxInfo function (winuser.h)
https://docs.microsoft.com/de-de/window ... mboboxinfo

now i have to look how to get it work under harbour

hi,

i found "Handle" of Listbox-Part in Combobox : COMBOBOXINFO Structure (winuser.h)
https://docs.microsoft.com/de-de/window ... mboboxinfo

i have found that COMBOBOXINFO Structure is used by some FiveWin HB_FUNC which i modify for HMG

after found out that Constant

Code: Select all

#define LBS_USETABSTOPS        128  //    0x80

is not used in HMG i try to "add" it with

Code: Select all

   HMG_ChangeWindowStyle( nHwnd1    , LBS_USETABSTOPS , NIL , .T. )

than i call HB_FUNC

Code: Select all

   LISTBOXSETMULTITAB(nHwnd1, aTabStops )

from MiniGUI Extendet Version but it does not work ...
