Single Toobar Simultaneously Used by Multiple Dialog-Based Applications At Once

Environment: VC6 SP3, Windows95/98/NT4/2000

TlbDlg_OK is a sample how to work with common toolbar from several dialog-based applications.

Project TlbDlg_OK (see Downloads demo and source files) creates 2 applications
  • tb.exe (toolbar)
  • TbDlg_OK.exe (dialog application)
  • >

What to run at first - TbDlg_OK.exe or TB.exe is not important.
Click several times exclamation mark in TB.exe to run several instances
of TbDlg_OK.exe.

Move focus to any of them - common toolbar (TB.exe) moves automatically
in its area.

Common toolbar will be closed when a last instance will be closed.

TbDlg_OK.exe sends to TB.exe the following messages (see resource.h) to add and delete connections between two applications and to move tb.exe placement:

ID_CONTROL_ADD_HWND
ID_CONTROL_DELETE_HWND
ID_CONTROL_SET_FOCUS

TB.exe sends to TbDlg_OK.exe the following messages (see resource.h) in accordance with icons, that are set in tb.exe:

ID_CONTROL_NEW_INSTANCE
ID_CONTROL_NEW
ID_CONTROL_OPEN
ID_CONTROL_SAVE
ID_CONTROL_HELP

Their implementation is carried out in TbDlg_OK\TbDlg_OKDlg.cpp as usually:

ON_COMMAND(ID_CONTROL_NEW,OnNew)
ON_COMMAND(ID_CONTROL_OPEN,OnOpen)
ON_COMMAND(ID_CONTROL_SAVE,OnSave)
ON_COMMAND(ID_CONTROL_HELP,OnHelp)

TB.exe is a simple application that contains toolbar only. Its size is equal toolbar size (see tb\mainfrm.cpp variables CONTROL_BAR_WIDTH and CONTROL_BAR_HEIGHT).
