Speaking of which, I encapsulated it in a procedure (TWaitForm is the spash
screen, Aproc is a procedure of object, TExecInThread simply calls AProc in
its execute method):
procedure ExecWithSplash(AProc:TThreadProc);
var wf:TWaitForm;
ut:TExecInThread;
begin
Wf:=TWaitForm.Create(Application);
WF.Show;
ut:=TExecInThread.create(AProc);
while not ut.Finished
Application.ProcessMessages
wf.free;
if ut.FatalException<>nil then
raise(ut.FatalException);
ut.free;
Ehm. In case of an exception, ut will never be freed ?
