Lost Focus on showDialog (Windows Application)

I'm developing a windows aplication that starts in a main form and when user selects FILE/NEW PROJECT, a wizard is displayed (in modal way). This wizard is a sequence of forms displayed with showDialog. Each step of the wizard has a NEXT button and a BACK button. The code is like these:

When FILE/NEW PROJECT menu of main form is selected:
step1Form.showDialog();

When NEXT button of step 1 is pressed:
step1Form.hide();
step2Form.showDialog();

When NEXT is pressed, the main form lost focus for any windows aplication running (word, excel, explorer, IE, etc...) and the step2Form appears in front of it. Now, we have my main form hidden by a windows application and the step2 form in front of the windows application. There's a file sample in:

This is the original error!

This is a try to solve it (not good yet)!

Como voce é brasileiro, ai vai....

Uma sugestão, voce poderia usar paineis ao invés de usar vários forms.

Em cada painel teria a sua "tela" e voce iria ocultando e exibindo a cada etapa.

Espero ter ajudado.

You might consider saving yourself a lot of time by using an existing wizard in your code...

There's many more out there also... good luck.

Cheers,

AaronReams, thanks for the tip but I won't use a 3rd party wizard in this project because I need total control on this forms and all of its design and code is already done.

TomasX2, the problem occurs when the hide() is called, so, I think that nothing after hide() will make some difference, but I tryed your solution and didn't work.

SideB, your idea of using panels to do the steps is a nice one, but I think there's a way to show a sequence of dialog forms without lose the focus. I'm probably missing something...

Using panels make de interface management more dificult...

Thank you anyway, I will try it later.

I think the showDialog with the IWindow32 parameter tells the form who the parent is...
when you created the step1 form from the main form did you create it with a step1Form.showDialog(this) overload or just the regular...

I tried this at home yesterday and I did it like this and it worked out better than without the overload.

// main form
step1Form = new Form2();
step1Form.showDialog(this);

// step one form on next click...
this.Hide()
step2Form = new Form3()
step2Form.showDialog(this);

// step two on back
this.Hide()
step1Form = new Form2();
step1Form.showDialog(this);

tomasX2, the results of your code is almost good, in fact, much better than without overload, but it still with a strange behavior, like a flick when the hide() is called. I got something like this in the example I posted at:

http://www.tecgraf.puc-rio.br/~nazareth/code/TesteBugShowModalMelhor.zip

I need smooth transition between forms, any idea?

Thank you for the help.
