Maintaining one visible form with CF2.0

Hi,

I have recently created a CF2.0 Pocket PC application using VS 2005 Beta 2 after being inspired by the following white paper:

"Northwind Pocket Service: Field Service for Windows Mobile-based Pocket PCs"

available at:

When opening and closing all forms in my application I use the method used in the white paper which is described in an extract from the white paper below:

+++++++++++++++++++++++++++++++++

The code that runs when the first menu option (Plan) is selected looks like this:

Cursor.Current = Cursors.WaitCursor;
PlanForm planForm = new PlanForm(this);
planForm.ShowDialog();

 
 

During the load of the new form, the wait cursor is shown. Also note that the current form instance is passed as a parameter to the child form (PlanForm) to allow the child form to control the parent form's visibility.

This is what the PlanForm constructor looks like:

public PlanForm(Form parentForm)
{
   InitializeComponent();
   this.parentForm = parentForm;

} 

 

The parent form instance is saved in a private variable (parentForm) that is used in the form's load event:

private void PlanForm_Load(object sender, EventArgs e)
{

   parentForm.Hide();
   Cursor.Current = Cursors.Default;
} 

 

It is used to hide the parent form and remove the wait cursor. Also, it is used when the form closes:

private void PlanForm_Closing(object sender, CancelEventArgs e)
{
   parentForm.Show();
} 

 

The parent form is shown again. The reason for doing this is that there will be only one instance of the application in the current running programs list (Start > Settings > System > Memory > Running Programs).

+++++++++++++++++++++++++++++++++

This works fine for a CF1.1 application created in VS2003.  However when I use the above method in a CF2.0 application, the application momentarily disappears when a form is shown.  I think this is due to the load event running 'parentForm.Hide();' before the form that is being loaded is visible.

Please can someone help me out with this issue
