Change The Focus from Forms
Hi there,
I'm developing an application but i've got the following problem:
This is the cenario:
1. You open the application and you get a Splash Screen,
(Let's call it SpashForm)
2. It then goes to another form called PasswordDlg.
3. When you enter the right Password, it goes to the main form.
(The Problem Comes here)
4. From the main form you minimize to the TRAY, which contains a Popup menu with Open and Exit.
Now when you click on open i want the PasswordDlg form to come out and ask you for the Password again....and so on..
My Problem is that the PasswordDlg form shows up but cannot write on it, because it is not focused.
What can i do to make it work please?
Thanks

Show actually does call bringtofront :)
procedure TCustomForm.Show;
begin
Visible := True;
BringToFront;
end;
so there is no need for BringToFront :)
also use Windows.SetFocus(pwForm.Ha ndle);
procedure TCustomForm.Show;
begin
Visible := True;
BringToFront;
end;
so there is no need for BringToFront :)
also use Windows.SetFocus(pwForm.Ha

The main form is still there and when pwform shows up it works like it's disabled and will not let me write the password on the TEdit component, or close the form or anything :-(

? looks like as you show your mainform modal
lee,
thanks for the look into the vcl-source,
but sometimes a call twice works better

Probe using API function :
SetActiveWindow(pwform.han dle);
:o)
SetActiveWindow(pwform.han
:o)

It only works when i say: if....then Form1.Showmodal
else....
.....etc
And this brings back my previous problem :-(

Now it does'nt do anything when i insert the password :-(
this is the code for PasswordDlg Form:
procedure TPasswordDlg.OKBtnClick(Se nder: TObject);
begin
If Edit1.text=Memo1.text then SetActiveWindow(Form1.hand le)
else
MessageDlg('You have enter a wrong password!', mterror, [mbOK], 0);
Edit1.Clear;
Edit1.SetFocus;
end;

MessageDlg('You have enter a wrong password!', mterror, [mbOK], 0);
Edit1.Clear;
Edit1.SetFocus;
end;
stohanzl,

NOW...if i use:

If Edit1.text=Memo1.text then form1.showmodal
else
MessageDlg('You have enter a wrong password!', mterror, [mbOK], 0);
Edit1.Clear;
Edit1.SetFocus;
end;
Then it will go to the main form but will not let me insert the password when i call back PasswordDlg form from the tray :-(

btw. i'm a bit confused,
could you explain how and
in which order you create and show your forms?

Sorry, it still does not work

OK,
1. You open the application and get a SplashForm, which after goes to another form called PasswordDlg, then if
you enter the right password it goes to Form1, which it the main form, on it, if you minimize the main form it goes to the Tray.
When you right click on the TrayIcon...It calls back the PasswordDlg form, prompting you to enter the password but when the PasswordDlg is shown it doesn't let me do anything, it's like disabled but not greyed.

This is the code from the PasswordDlg that checks the password:
procedure TPasswordDlg.OKBtnClick(Se nder: TObject);
begin
If Edit1.text=Memo1.text then form1.showmodal
else
MessageDlg('You have enter a wrong password!', mterror, [mbOK], 0);
Edit1.Clear;
Edit1.SetFocus;
end;
procedure TPasswordDlg.OKBtnClick(Se
begin
If Edit1.text=Memo1.text then form1.showmodal
else
MessageDlg('You have enter a wrong password!', mterror, [mbOK], 0);
Edit1.Clear;
Edit1.SetFocus;
end;
How do you CREATE the Pwd... dialog.. :
Pwd := TPwd.Create(Self)???
In this Case I think is better use Pwd := TPwd.Create(Application);
Probe IT...
Pwd := TPwd.Create(Self)???
In this Case I think is better use Pwd := TPwd.Create(Application);
Probe IT...

Any Ideas please?

The password is loaded from an eternal file but it's really calling back the PasswordDlg form that's giving me the headache

What about if on minimzing the Main Form i kill it...would that work?
Sfern
Sfern
well ok, you call form1.showmodal
that means this form1 must be closed
before any other form can get the focus.
also just use
form1.close
before
you show the passwordform
(the passwordform is the logical application-mainform,
i guess)

>it...would that work?
i guess yes,
but instead of kill a simple close should do it also,
so you don't need to recreate the form again

But this will mean that i would have to write some code to detect if windows is shutting, in order to prompt with a dialog

I'm basically writting a folder locking application, which detects shutdown, and checks internet connection because if the folder is locked it stops any windows based viruses from infecting the stuff insterted there...It also stops deleting, copying, renaming etc...just giving it final touches :-/

hope it works
if you do this circular,
then the flag must be set to false again
this you can do in your password-routine like
procedure TPasswordDlg.OKBtnClick(Se nder: TObject);
begin
If Edit1.text=Memo1.text then
begin
form1.fpwshow := false;
form1.showmodal
end
else
begin
MessageDlg('You have enter a wrong password!', mterror, [mbOK], 0);
Edit1.Clear;
Edit1.SetFocus;
end;
end;
