Hi all.

I have a strange problem.

If I install my expert in IDE (right click in progect manager->Install)
I can invoke the expert with click on a specially added 'Tools' menu
item; I see the expert's form and all works like a charm.

But clicking menu (my menu item is still in the right place) doesn't
show the form after restarting of the IDE; IDE caption becomes inactive
but exspert is invisible. It looks like the expert becomes active but
it is offscreen or in wrong Z-order. Now I can start a dummy test
project (expert is still invisible and I can't show it by repeated menu
clicks); but arter finish of the dummy progect the expert becomes
visible and all works like a charm again!

I use the DockingForm example from "Erik's Open Tools API FAQ and
Resources" page (http://www.gexperts.org/opentools/):

unit BaseDockForm;
...
procedure ShowDockableForm(Form: TBaseDockableForm);
begin
  if not Assigned(Form) then
    Exit;
  if not Form.Floating then
  begin
    Form.ForceShow;
    FocusWindow(Form);
  end
  else
    Form.Show;
end;

I've already tried to add

    Form.Visible:=true;
    Form.BringToFront();
    Form.Activate;

in different combination with no luck ...

Can anyone help?

TIA

After trying to show your form, print out a debug message containing the 
form's Top/Left, Height/Width, Visible, Position, FormStyle, WindowState, and 
Parent.Name (if available) and see if the form is really in the location and 
state you expect.

OK, I'll try it.
But I quite sure that all values are in proper ranges ...

Results:
 Top=210 Left=278 Height=379 Width=837
 Visible=true Position=poDesigned
 FormStyle=fsNormal  WindowState=wsNormal
 Parent=nil

Additionally:
 BoundsRect=(278, 210, 1151, 589, (278, 210), (1151, 589))
 ClientOrigin=(282, 230)
 ClientRect=(0, 0, 865, 355, (0, 0), (865, 355))
 Floating=True
 Dockable=True
 Active=True
 Enabled=True
 ModalResult=0
 AboutToDestroy=False
 FormState=[]
 BorderStyle=bsSizeToolWin
 SaveStateNecessary=True
 AutoSave=True
 DeskSection='frmArrayInspector'
 LoadedFromDesktop=True
 IDEDockType=dtJoin
 VisibleOnUndock=False // ?

I've tried VisibleOnUndock=True - no effect ...

Parent=nil, is this OK ?

OK, fixed.

The example has Register procedure:

procedure Register;
begin
  RegisterPackageWizard(TDockFormExpert.Create as IOTAMenuWizard);
  TExampleDockableForm.CreateExampleDockForm;
end;

(In fact I saw a lot of examples with the similar code)

I saw no problem in debugger (no exceptions, strange values etc) but my
expert was invisible (+ some other oddities).

I've removed the form creation from the Register procedure. Form
constructor now works after the first click on my IDE menu item and all
goes OK.
