Hi,

I used Win32::GUI to develop a Window (actually two windows) only from main window one can access the sub window. I opened the sub window from main window and did some activity and closed it. When i opened that sub window second time the info are still there.

Can i able to clear all the contents which the win32::GUI holds by form close.

I have tried undef by exiting, can't able to access the window second time.

    What are you trying to reset? if you are trying to reset input fields (ie: text box, list box, etc.) and you use the hide function to close/hide the sub window, then your window is still there with all of the data you input. You should create a function to reset the window to the default state when you execute any of the following events: Deactivate(), Hide() or Terminate() event. See onTerminate below. 
    
$Main = Win32::GUI::Window->new(
   -name  => 'Main',
   -title => $appname,
   -pos   => [10,10],
   -menu     => $MainMenu,
   -maxsize => [500, 660],
   -onTerminate => \&Exit_Click,
   -onMinimize => \&DoHideMe_Click,
   -onTimer     => sub{TimedOperation_Timer()},
   -size  => [500,650], );

      Hi,

      Thanks, for your response. I want to reset all input fields and window should return to its original state, without holding any input resources.
