Hi all,

We've got an application that, when started, displays a login window. We'd like the window to be the active window, and the focus to be on the username textbox. We call the Activate() method in our overridden OnContentRendered method, and this works fine on real, physical machines, but for some reason, on VMWare, it doesn't work. It doesn't seem to work through VMRC either. The Activate() method, when called, actually returns false to indicate that it failed.

Does anyone know what might cause the Activate() method to return false ?

Hi Ssebu,

I try with the following code but cannot reproduce the problem, the Activate method returns true either on local physical machine or VMWare. Could you show us the code you used?

public partial class Window1 : Window
{
public Window1()
{
InitializeComponent();
}

void Window1_Loaded(object sender, RoutedEventArgs e)
{

Window2 w = new Window2();
w.Show();

}
}


public partial class Window2 : Window
{
public Window2()
{
InitializeComponent();
}

protected override void OnContentRendered(EventArgs e)
{
bool b = this.Activate();

MessageBox.Show(b.ToString());

base.OnContentRendered(e);
}
}


Best Regards,
Zhi-Xin

Hi Ssebu,

Could you provide the sample project to reproduce the problem?

I tried Zhi-Xin Ye's sample, and indeed it doesn't reproduce the problem. In our case the application is very big and complex, so there's probably something in our code that causes the behavior. I'll try to find exactly what it is that does that, but for now no, I don't have a better sample. Sorry.
