[RESOLVED] CF 3.5 - Alternative to Shown event ?

[FrenchFry]

Hi there,

I'm developping an application for Pocket PC but I don't have the Shown event for a form.
During FORM_A loading, I check some values and sometimes I need to open FORM_B.

But FORM_B is opened before FORM_A, so I can't see it. And I don't want my users to click on a button to open FORM_B, I want this check to be automatically done by my program.
My solution would be to use FORM_A.Shown() event, but I don't get it.. Maybe because I'm programming for Smart Devices?

Is there any alternative, tricks to simulate it ?

Thank you

The Shown event hasn't actually been supported from the beginning of .NET. It was only introduced in .NET 2.0 I think. Before that we had to use the Activated event and use our own Boolean flag to differentiate between the very first instance of that event, which occurs when it is first displayed, and any subsequent instances. You can do exactly the same.

Thank you for your answer and explanation,
I try to initialize a glob boolean variable to False during load event.

Then in validated event I did like :

Class FORM_A
{
Dim myVar as Boolean = False // I tried this the 1st time 
sub FORM_Load().Load
{
    myVar = False // I tried this the 2nd time
}


sub FORM_Activated().Activated
{
     If myVar = False then
          FORM_B.Show
          myVar = True
     End If
}
}

Nothing seems to happen... FORM_B doesn't show itself... I replace FORM_B.Show by a Msgbox and it popup many times before my app crashs.

I think I've found a solution which seems to work.

To open a new form during the loading of an other form, I replace .Show() to .ShowDialog().
