How can you load a dll as an application? A "loader program does not sound like the same thing as a project exe to me. Perhaps you elaborate on that because what you've described sounds highly improper to me.

I have a small application which basically consists of a MDI form which acts as host to a series of plugin forms. The application is relatively immature and subject to change. The application is only used at one site and all users have access to a shared directory on the network where the most up to date versions of the plugins are kept, this means it is relatively easy to check that the application always has the latest versions of the plugins. Recently I have suffered from a bit of 'project creep', and I was looking at a way of applying the same system of updating the applications main form. The Problem... I decided to move all of the MDI Form (ie pretty much the whole application) into a dll, create a Loader program which checks the (local) dll version number against the (network) dll and downloads it as necessary and then loads the dll and opens the form. This all seems to work fine, except... when the MDI form is closed the application crashes with an unknown exception. I've checked the MDI Form and as far as I can tell every object that is created as the form loads is freed and it unloads. The following is the Code for the Library Project. library FEBAPI; uses ShareMem, madExcept, madLinkDisAsm, Forms, Dialogs, MainUI in 'Source\MainUI. pas' {FrameworkUI} ; {$R *.res} procedure RunFEB; stdcall; var FrameworkUI: TFrameworkUI; begin FrameworkUI := TFrameworkUI. Create(nil) ; FrameworkUI. ShowModal; FrameworkUI. Release; end; exports RunFEB; begin end. When stepping through the RunFEB method, after FrameworkUI. Release is called, there are repeated calls to stdWinProc (around 5 at last count) until the Application crashes with an unknown exception. Any pointers most gratefully received.
