| #12122 | obsolete | SendInput keys sometimes missing. | ||
| Description |
I have been trying to use a combination of Dragon NaturallySpeaking 12.5, NatLink and a Python extension, DragonFly 0.6.5 to translate voice commands into keyboard events. When the target window is Notepad, it seems work flawlessly, but when the target is a VirtualBox guest, some keys may be missed. I have debugged the DragonFly code, which uses a Python wrapper around the WinAPI call SendInput to generate the key presses and releases. I verified that the input to the SendInput looked correct during an incidence of this behavior. I guessed VirtualBox devs would have a rough time reproducing this software setup, and I wasn't confident I could make an easy test case of SendInput. So, I set out to make an AutoHotkey script to demonstrate the issue:
space::
SendInput if{space}(){enter}{{}{enter}
;SendPlay if{space}(){enter}{{}{enter}
;SendEvent if{space}(){enter}{{}{enter}
return
; is a comment character and interestingly, the 1st and 3rd commands did work with Notepad but none produce any input other than a space with the VirtualBox guest (does this mean VirtualBox uses some kind of key hook?). I can't confirm which of those commands might use SendInput internally, but I can tell you I've tried compiling and running the script in elevated mode with no improvements. I have tried posting about this issue on the forums already. |

| #10015 | obsolete | "Object reference not set to an instance of an object" - .NET Framework 4 | ||
| Description |
PC: Windows 7 Ultimate Virtual Machine: Windows XP Professional SP3 Hi, I am trying to run an application that was developed using the .NET Framework 4. When I run it I receive the error "Object reference not set to an instance of an object" along with a detailed error log. When I run this on my native OS I do not receive the error, and I have exactly the same versions of the .NET Framework installed. After receiving advice from several sources they pointed out it's most likely the Virtual Machine software, i.e. Virtualbox. The error log I get is: See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box. Exception Text System.NullReferenceException: Object reference not set to an instance of an object. at A.R.Z() at A.R.CB(Object A, EventArgs B) at System.Windows.Forms.Form.OnLoad(EventArgs e) at System.Windows.Forms.Form.OnCreateControl() at System.Windows.Forms.Control.CreateControl(Boolean fIgnoreVisible) at System.Windows.Forms.Control.CreateControl() at System.Windows.Forms.Control.WmShowWindow(Message& m) at System.Windows.Forms.Control.WndProc(Message& m) at System.Windows.Forms.ScrollableControl.WndProc(Message& m) at System.Windows.Forms.ContainerControl.WndProc(Message& m) at System.Windows.Forms.Form.WmShowWindow(Message& m) at System.Windows.Forms.Form.WndProc(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.Control.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) Loaded Assemblies mscorlib Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.3625 (GDR.050727-3600) CodeBase: file:///c:/WINDOWS/Microsoft.NET/Framework/v2.0.50727/mscorlib.dll PuzSol Assembly Version: 1.0.0.0 Win32 Version: 1.0.0.0 CodeBase: file:///C:/Documents%20and%20Settings/Administrator/Desktop/YPP/PuzSol%20BoS/PuzSol%20BoS.exe System.Windows.Forms Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.3623 (GDR.050727-3600) CodeBase: file:///C:/WINDOWS/assembly/GAC_MSIL/System.Windows.Forms/2.0.0.0__b77a5c561934e089/System.Windows.Forms.dll System Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.3624 (GDR.050727-3600) CodeBase: file:///C:/WINDOWS/assembly/GAC_MSIL/System/2.0.0.0__b77a5c561934e089/System.dll System.Drawing Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.3053 (netfxsp.050727-3000) CodeBase: file:///C:/WINDOWS/assembly/GAC_MSIL/System.Drawing/2.0.0.0__b03f5f7f11d50a3a/System.Drawing.dll PuzSolPuzSolPuzSol Assembly Version: 1.0.0.0 Win32 Version: 1.0.0.0 CodeBase: file:///C:/Documents%20and%20Settings/Administrator/Desktop/YPP/PuzSol%20BoS/PuzSol%20BoS.exe System.Management Assembly Version: 2.0.0.0 Win32 Version: 2.0.50727.3053 (netfxsp.050727-3000) CodeBase: file:///C:/WINDOWS/assembly/GAC_MSIL/System.Management/2.0.0.0__b03f5f7f11d50a3a/System.Management.dll JIT Debugging To enable just-in-time (JIT) debugging, the .config file for this application or computer (machine.config) must have the jitDebugging value set in the system.windows.forms section.

| #870 | fixed | Remove Virtual HD options contrary to Gnome HIG | ||
| Description |
As I posted here: https://bugs.launchpad.net/ubuntu/+source/virtualbox-ose/+bug/160798 Using VirtualBox-OSE 1.5.0 in Ubuntu Gutsy (current to the repos as of Nov. 7, 2007) [dAniel hAhler wrote: "Confirmed. This is the same with version 1.5.2"] I wanted to remove a virtual hard drive. The option buttons are: [Yes] [No] [Cancel] Now, while there is explanatory text visible, those options are contrary to the Gnome Human Interface Guidelines for Alerts: http://developer.gnome.org/projects/gup/hig/2.0/windows-alert.html "Button Phrasing. Write button labels as imperative verbs, for example Save, Print. This allows users to select an action with less hesitation. An active phrase also fits best with the button's role in initiating actions, as contrasted with a more passive phrase. For example Find and Log In are better buttons than than Yes and OK." I suggest changing "Yes" to "Delete" and "No" to "Unregister". [dAniel hAhler added: "I think we should not add a patch for this [in Ubuntu], because it affects messages (translations) and is likely to get accepted upstream as a good change.] |
