Hi Everyone. I have developed a small dataentry winforms application in c#. But the application is getting closed while pressing Arrow keys just after pressing ALT key in text boxes. It is not happening if we press any keys other than ALT. I am getting the following exception as well:
Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object at System.Windows.Forms.MenuTracker.ProcessKeys (System.Windows.Forms.Message& msg, Keys keyData) [0x00000] at System.Windows.Forms.Menu.ProcessCmdKey (System.Windows.Forms.Message& msg, Keys keyData) [0x00000] at System.Windows.Forms.Control.ProcessCmdKey (System.Windows.Forms.Message& msg, Keys keyData) [0x00000] at System.Windows.Forms.TextBoxBase.ProcessCmdKey (System.Windows.Forms.Message& msg, Keys keyData) [0x00000] at System.Windows.Forms.Control.InternalPreProcessMessage (System.Windows.Forms.Message& msg) [0x00000] at System.Windows.Forms.Control.PreProcessMessage (System.Windows.Forms.Message& msg) [0x00000] at System.Windows.Forms.Control.PreProcessControlMessageInternal (System.Windows.Forms.Message& msg) [0x00000] at (wrapper remoting-invoke-with-check) System.Windows.Forms.Control:PreProcessControlMessageInternal (System.Windows.Forms.Message&) at System.Windows.Forms.Application.RunLoop (Boolean Modal, System.Windows.Forms.ApplicationContext context) [0x00000] at System.Windows.Forms.Application.Run (System.Windows.Forms.ApplicationContext context) [0x00000] at System.Windows.Forms.Application.Run (System.Windows.Forms.Form mainForm) [0x00000] at DETool.Forms.LoginForm.Main () [0x00000] mono version: 2.0.1-4 operating system : ubuntu 9.0.4 Thanks in advance Jijesh -- View this message in context: http://www.nabble.com/application-crashes-on-pressing-ALT%2CArrow-keys-tp24627006p24627006.html Sent from the Mono - WinForms mailing list archive at Nabble.com. _______________________________________________ Mono-winforms-list maillist - [email protected] http://lists.ximian.com/mailman/listinfo/mono-winforms-list
