How to display message box without any buttons in C#

Question

The probl

Answer 1

Create a simple form with the message (or expose a public property to be able to change the message, or a constructor with message parameter to pass it in) and show the form using this Show overload. Then disable the (entire) original (owner) form (or just disable the controls you don't want accesible).

So, in your "main" form do this:

Form f = new MessageForm();
f.Show(this);         //Make sure we're the owner
this.Enabled = false; //Disable ourselves
//Do processing here
this.Enabled = true;  //We're done, enable ourselves
f.Close();            //Dispose message form

Also, consider using a BackgroundWorker.

Answer 2

create custom form, and write own behavior

Answer 3

One way you could do it is create a worker class that raises an event when it is finished.

execute the worker class in a new thead so it runs it the backgroud.

create the modal form with a method to close it as the event handler for the "finished" event. This way the ui still works and responds and the form will close once the worker thread is finished.

Create a custom form set it to minimal styles etc. Make sure it knows when the process is complete, say by passing in a reference to the process and checking it every now and then.
