Problem displaying a messageBox in .NET CF

[alexbisson]

Hi,

I'm working on a WinForm application with .NET CF 2.0 and I have a background running thread that needs to notify the user about various events. The problem is that everytime I want to notify the user with a MessageBox about an event, the application exits once the messagebox is displayed...I get the following message in the output window: The thread 0x2eda2a2 has exited with code 0 (0x0).

However, if I display the message in a label of my form, everything works well...here is the code I use:

public void DisplayMessage(string message)
        {
            if (InvokeRequired)
            {
                DisplayMessageDelegate displayMessageDelegate = new DisplayMessageDelegate(DisplayMessage);
                this.Invoke(displayMessageDelegate, new object[] { message });
            }
            else
            {
                this.labelStatus.Text = message;  // Works well
                MessageBox.Show(message, "Info", MessageBoxButtons.OK, MessageBoxIcon.Exclamation, MessageBoxDefaultButton.Button1); // Application exits when called
 
            }
        }

Thanks in advance!
alex

What's wrong with just using System.Windows. Forms.MessageBo x.Show()?
I use CF2.0 as well and have not run into the those issues. I also never did any of that invoke stuff.
If your errorhandling set to do anything after it pops up that messagebox?

What language are you using?

I'm using C#...

My method DisplayMessage( string) used to be only { MessageBox.Show (message) }, but I've added the Invoke section when I've started to display the message on the label of my form (which works well...). Since the DisplayMessage method is called from my 2nd thread, I need to use Invoke() to update the label, which is on my Form thread, or the app crashes.

I know that I don't need the Invoke() to display the messagebox, but I have the same problem if I remove it.

Thanks!
