[SOLVED] DLL Form

[pmesquita]

Guys..

I'm trying to solve a rather trivial problem:
Form inside a DLL.

The problem is: I have a DLL that has a Form that asks a question and returns True or False... but I need it to be displayed in ShowModal. The problem starts because when calling the DLL function responsible for displaying the form it is superimposed on the application and I would like you to be superimposed on the form that called the application... because my application is MDI.

I tried to send the "Application" Handle to the DLL and associate it to the "Application" of the DLL but the Form is not displayed

The closest I got to a resolution is this link...
http://www.44342.com/delphi-f1278-t4782-p1.htm the form is created but is not displayed.

Any idea ?

Well then... I came across this example but I need the form to be modal and not like this in the example that the form is "inside" the panel or parent form... I need the MessageBox style but this form inside a DLL... or some other modularization idea... because I'm fragmenting some functions into dlls so I don't need to recompile the whole exe when I make a simple change...

Yes, but why didn't you modify the above example to behave like a ModalForm(see attached application)?

Dude... it worked perfectly...
Actually, I did more or less what you did but I was "hitting my head" with the fact of deactivating the parent form before calling the fom that is in the dll... I didn't think I would have to do this...
But now I've learned another EnableWindow function...

Thanks...
