I use the lazarus 1.6 with FPC 3.0 in x64bits.

My code for calling is:

...
var
  Application: LAppConsolev1;
  objForm : TForm1;
begin

  Application:=LAppConsolev1.Create(nil);
  Application.Title:='LAppConsolev1';
  Application.Initialize;

  objForm := TForm1.Create(nil);
  objForm.Show;

end.   

Where TForm1 is defined in another file, and is a simple form with a label, textfield and one button.

I search in internet by I can not resolve the execution problem. The compilation is ok but not execute.

¿Could someone please help me to solve the problem?

Thank you.

Sorry, I don't think you can mix and match Console and GUI applications.  I certainly can't think of any other console program program I've ever come across having a GUI.

Can you re-write your app entirely as a GUI?   Or, can you break them into two different projects, and in the console use TProcess to automate the GUI app?

Hello Mike, Yes I can re-write de app entirely as a GUI, and I think that is better.

Thank you.

It is perfectly possible under windows to mix and match console with gui. All you have to do is create your GUI project as {$apptype console} and your GUI application has a console too.
Now it depends on when and where you need your GUI form.
1) It maybe that it should immediately show: nothing extra
2) It may be that you want the form(s) hidden: Just call hide or set a property visble at design time.
3) It maybe that you want to create your forms manually: proceed as can be found in the wiki topic.

All of these work in both Delphi and Lazarus under win32/64. Not sure about other platforms.
[edit]
Note that you have to provide some - but not all - console handling yourself.
