Greetings Dan.
I had another contributor to this list help me with converting the Bome
OneInstance component to use with Delphi 2010 and although it compiled, it
was acting strange in that it would place multiple icons in the tray when
calling a second and third time. So thanks for pointing me to this
component. I already had the JVCL installed so it was a slam dunk to use
it. Very nice component and it works as expected.
Thanks,
Mike

Subject: Re: One Instance Component that support passing of parmeters
JVCL has a component like this called TJvAppInstances, I believe it's
under Jv System. It supports passing command line parameters to the
running instance.
"The TJvAppInstances component encapsulates the TJclAppInstance class. It
allows you to control the number of application instances running at the
same time. If a new instance is rejected it can send its command line and
other commands to the first instance. To set a UniqueAppIdGuidStr you must
call JclAppInst.JclAppInstances in the initialization section of a unit or
before the forms are created (OnCreate is too late). This class is not
thread safe."

I use it, it works.

Greetings All,
I need a Delphi component that will allow only one instance of my
application to be run.
I also need it to support passing in of parameters.
In other words, it does not matter if I'm running the app for the first
time, or second or third. I will be passing it parameters that must be
used each time the app is called.
In Delphi 5 I had a component called Bome TOneInstance that worked great
as it had an event called OneInstanceStarted which was the event I could
retrieve the parameters and process them accordingly. Bome TOneInstance
is no longer supported at or even mentioned at www.bome.com
In Delphi 2010 I tried to install this same component and it errors out
while compiling the code and I have no idea how it fix it, so looking for
a replacement.
Please reply if you can assist in locating a replacement or have any
suggestions on how to deal with this.
Thanks,
Mike
