java - NetBeans - How to show all Swing components in a JFrame? -

-

I am creating a swing GUI with NetBeans, using the builtin form maker, which works quite well.

However, if I accidentally put a wrong panel on a form, then I have no way to remove it, or choose it again.

Similarly, if I want a button to open a new window, say, a file selector, I do not know how to add that file selector to the form, but it does not appear until then As long as the button was not pressed.

Does anyone have any experience with NetBeans Swing Form Builder? It seems like a normal thing to do, but I do not think how to do it. Am I missing something?

A Netbeans user! Yes, the bottom left corner should have a Navigator window. There it displays all the components of the form. I'm not even sure what you mean by a file selector, but to open a new window, i.e. another geform, you create another form class. Then you form and visit that form.

To say that you have a form main program and helpMenu

main program 

  Public key programs () {InitComponents (); // On the lines of that help, some menu menus on the menu: = New help menu (vindo); HelpMenu.setVisible (true); }   
 With this you will be able to open a new window, but if you click on the red X to close the window, it closes the entire program in the Help menu. In the properties you can choose the option for what to do when you exit the window.  
 Exclude  
 Hide anything  
 Do nothing Do the code to run in the code above before appearing in JPEG, if you want to show or hide items, Then just code  
  object .Setable (boolean);   
 I hope I have answered your question Tetramputechture.

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i
