Hi,

Do you tried ExitProcess Win32 API function?

Use either ExitProcess() or TerminateProcess() Win32 API's. However, bear in
mind that
ExitProcess is the preferred method of terminating a process since it calls
the entry-point function
of all attached DLLs with a value indicating that the process is detaching
from the DLL.

Application->Terminate() simply posts a WM_QUIT message to the message
queue, which will not be processed until later on when the queue begins
being pumped for messages.

If you are doing your initialization in the MainForm's constructor, then
simply throw an exception to indicate a failure. An exception is the only
way to return a failure from a constructor. Throwing an exception from the
MainForm will prevent the other forms from being created.

The alternative is to alter the project's WinMain() function directly, to do
your initializations before the first form is ever created. Then you can
bort your program more gracefully when needed.
