Two Windows taskbar tabs

rbuser

RB Ent 11, Delphi 2007. I have an application which displays a report
designer. It was ported from Delphi 5, RB 7. When run under Vista I see
two taskbar tabs, one with the RB icon and one blank. When run under
Windows 2008 Server I see two taskbar tabs, one with the icon set for
my executable, and one with the RB icon. When run under XP, I only see
one tab, with the RB icon.

Setting MainFormOnTaskbar explicitly true or false seems to make no
difference. Any ideas to get rid of the extra icon? At one time on 2008
I somehow lost the window and clicking either taskbar tab failed to
bring it back. It came back by displaying the process window from
Process Explorer. There is only one process running.

There is some internal Designer Window code that creates the task bar item.
That code has been in place for many versions. I think it was really meant
for the case in which the designer is being used within the Delphi IDE. I
modified it to not create the task bar item for runtime.

You can email support@digital-metaphors.com and request a patch to RB 11.

Your other issue, relates to recent versions of Delphi that include an
Application.MainFormOnTaskbar boolean property. For new projects, it
defaults to True. From the Delphi help file....

"The MainFormOnTaskBar property controls how Windows taskbar buttons are
handled by VCL.

If the property is true, a taskbar button represents the application's main
form and displays its caption. If false, a taskbar button represents the
application's (hidden) main window and bears the application's Title.

MainFormOnTaskBar must be true to use Windows Vista Aero effects. These
include live taskbar thumbnails, Dynamic Windows, Windows Flip, and Windows
Flip 3D. "
