Problem with MessageBox

Question

I have a problem with MessageBox, which should be modal.

Here is the situation

• User selects xx from the form
• MessageBox appears
• The user opens the built-in soft keyboard (built-in, from the device)
• The user closes the keyboard.
• MessageBox loses focus (as modality refutes it!), And the main form is shown in the foreground
• The application is blocking because the user cannot close the MessageBox.

Here is the code snippet for MessageBox.

MessageBox.Show("message", "caption", MessageBoxButtons.OK, MessageBoxIcon.Asterisk,
                                    MessageBoxDefaultButton.Button1);

Any ideas on how to solve this?

This is really the expected behavior in Windows CE (I'm not saying this is correct, just expected).

SIP , . "wierdness", " " - MessageBox , , .

, CF, MessageBox :

private void button1_Click(object sender, EventArgs e)
{
    //MessageBox.Show("message", "caption", MessageBoxButtons.OK, 
    //                                    MessageBoxIcon.Asterisk,
    //                                    MessageBoxDefaultButton.Button1);

    MessageBoxCE(this.Handle, "message", "caption", 0);
}

// renamed to not collide with the Windows.Forms MessageBox class
[DllImport("coredll", EntryPoint="MessageBox")]
private static extern int MessageBoxCE(IntPtr hWnd, string lpText, 
                                       string lpCaption, int Type);
