Hello,

I have a dll based expert that loads a hidden form that is used to communicate 
with an external program.  The form is created when the expert gets loaded 
and the code has worked correctly until Rad Studio 2007.  What happens in 
RS 2007 is the form is created and then is destroyed shortly after it is 
created.  I have found that if I delay the creation of the form until after 
the IDE has finished loading other libraries that it work correctly but the 
problem with this approach is that the time can vary depending upon what 
is loaded upon starting Delphi.  Is there a notification that I can use to 
get notified when the IDE has finished loading all of the libraries so I 
can wait for the notification to create my form?

Thanks for your time.

Dan

Hi Dan, IMHO use timeout is still the best solution. But there is 
another way. When you bind to IOTAService.FileNotification, you may know 
when the start up page is loaded into IDE. Then you can create your 
invisible form. However, if start up page is disabled by the user, this 
way fails.

I know that using an IOTAIDENotifier you can get a notification for when a 
package is loaded.  Therefore, why not use your delay strategy, but add time 
to your delay everytime a package gets loaded.  That way you're sure to not 
end your wait too early.
