Transparent background for SysTabControl32
#1
Hi Gintaras,
I was wondering if it is possible to make transparent background for SysTabControl32 i.e. for part that are not buttons (See attached screenshot).
When I give background of whole dialog a background color using DT_SetBackgroundColor, it makes the non-button part of TabControl visible. I tried to find a version of WM_CTLCOLORXX for tab control but couldn't. Any thoughts?
Thanks,


Function dlg_multipage_with_tab_control
Code:
Select All      Help
\Dialog_Editor
function# hDlg message wParam lParam
if(hDlg) goto messages

if(!ShowDialog("dlg_multipage_with_tab_control" &dlg_multipage_with_tab_control)) ret
