Hi

I am trying to create a class that displays a message in a panel which is centered on the screen... a simple 'please wait' would be fine, so that I can call something like

busy()

to display the message no matter what form is open in the application...

Any ideas how I get this to work?

Cheers

CD

Basically just how you described it.  Just use the .Show() method to show the window - that does not wait at that point.  In the form properties there is a setting for it to display centrally.

eg.
MyWaitForm frm = new MyWaitForm();
frm.Show();
....  //your code goes here
frm.Close();

Yes - or you could even pass a message into the form if you wanted different messages from the default you supply.

MyWaitForm frm = new MyWaitForm();
frm.DisplayMessage("Hello");
frm.Show();
....  //your code goes here
frm.Close();

in the form
public void DisplayMessage(String s)
{
  this.MessageLabel.Text = s;  //MessageLabel is the control you display the 'Please Wait' in
}

so simple

I was thinking of creating a class, which created a panel in code then added a label and an image, then set the message... but this is way easier.. thanks

The trick is the .Show() so it doesn't block the code.  However it does require you to close the form from code yourself.
