Crash when moving floating panel in Docking Manager MDI Demo in 4.1.0.62

[Raymond Gunawan]

Hi! I was playing around with the docking manager and managed to crash it in my application and in the MDI Demo sample. Here is how I did it in the sample: I run the MDI Demo sample Enlarge it a bit Take the bottom panel off its docked position Move that bottom panel around pretty wildly around the application (and probably outside the application too). The drawing seems to not be able to catch up with the movement, as it leaves a lot of "traces" behind. After a while, the app will crash. Here is the information from .NET: See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box. ************** Exception Text ************** System.Runtime.InteropServices.ExternalException: A generic error occurred in GDI+. at System.Drawing.Graphics.CheckErrorStatus(Int32 status) at System.Drawing.Graphics.FillRectangle(Brush brush, Int32 x, Int32 y, Int32 width, Int32 height) at System.Drawing.Graphics.FillRectangle(Brush brush, Rectangle rect) at Syncfusion.Windows.Forms.Tools.Renderers.RendererPrimitives.PaintGripper(Graphics g, Orientation orientation, Point location, Brush foreBrush, Brush backBrush, Int32 dotCount) at Syncfusion.Windows.Forms.Tools.Renderers.RendererOffice2003.PaintGripper(Graphics g) at Syncfusion.Windows.Forms.Tools.Renderers.RendererOffice2003.PaintCaption(Graphics g, PaintDockControlArgs args) at Syncfusion.Windows.Forms.Tools.Renderers.RendererOffice2003.PaintDockedControl(Graphics g, Rectangle rectangle, PaintDockControlArgs args) at Syncfusion.Windows.Forms.Tools.Renderers.DockingManagerRenderer.PaintDockedControl(Graphics g, Rectangle rectangle, PaintDockControlArgs args) at Syncfusion.Windows.Forms.Tools.FloatingForm.PaintNCArea() at Syncfusion.Windows.Forms.Tools.FloatingForm.WndProc(Message& msg) at System.Windows.Forms.ControlNativeWindow.OnMessage(Message& m) at System.Windows.Forms.ControlNativeWindow.WndProc(Message& m) at System.Windows.Forms.NativeWindow.Callback(IntPtr hWnd, Int32 msg, IntPtr wparam, IntPtr lparam) ************** Loaded Assemblies ************** mscorlib Assembly Version: 1.0.5000.0 Win32 Version: 1.1.4322.2032 CodeBase: file:///c:/windows/microsoft.net/framework/v1.1.4322/mscorlib.dll ---------------------------------------- MDIDemo Assembly Version: 0.0.0.0 Win32 Version: 0.0.0.0 CodeBase: file:///C:/Program%20Files/Syncfusion/Essential%20Studio/4.1.0.62/windows/Tools.Windows/Samples/Docking%20Package/MDIDemo/cs/bin/release/MDIDemo.exe ---------------------------------------- System.Windows.Forms Assembly Version: 1.0.5000.0 Win32 Version: 1.1.4322.2032 CodeBase: file:///c:/windows/assembly/gac/system.windows.forms/1.0.5000.0__b77a5c561934e089/system.windows.forms.dll ---------------------------------------- System Assembly Version: 1.0.5000.0 Win32 Version: 1.1.4322.2032 CodeBase: file:///c:/windows/assembly/gac/system/1.0.5000.0__b77a5c561934e089/system.dll ---------------------------------------- System.Drawing Assembly Version: 1.0.5000.0 Win32 Version: 1.1.4322.2032 CodeBase: file:///c:/windows/assembly/gac/system.drawing/1.0.5000.0__b03f5f7f11d50a3a/system.drawing.dll ---------------------------------------- Syncfusion.Shared.Base Assembly Version: 4.101.0.62 Win32 Version: 4.101.0.62 CodeBase: file:///c:/windows/assembly/gac/syncfusion.shared.base/4.101.0.62__3d67ed1f87d44c89/syncfusion.shared.base.dll ---------------------------------------- Syncfusion.Core Assembly Version: 4.101.0.62 Win32 Version: 4.101.0.62 CodeBase: file:///c:/windows/assembly/gac/syncfusion.core/4.101.0.62__632609b4d040f6b4/syncfusion.core.dll ---------------------------------------- System.Runtime.Serialization.Formatters.Soap Assembly Version: 1.0.5000.0 Win32 Version: 1.1.4322.2032 CodeBase: file:///c:/windows/assembly/gac/system.runtime.serialization.formatters.soap/1.0.5000.0__b03f5f7f11d50a3a/system.runtime.serialization.formatters.soap.dll ---------------------------------------- Syncfusion.Tools.Windows Assembly Version: 4.101.0.62 Win32 Version: 4.101.0.62 CodeBase: file:///c:/windows/assembly/gac/syncfusion.tools.windows/4.101.0.62__3d67ed1f87d44c89/syncfusion.tools.windows.dll ---------------------------------------- Syncfusion.Grid.Windows Assembly Version: 4.101.0.62 Win32 Version: 4.101.0.62 CodeBase: file:///c:/windows/assembly/gac/syncfusion.grid.windows/4.101.0.62__3d67ed1f87d44c89/syncfusion.grid.windows.dll ---------------------------------------- Accessibility Assembly Version: 1.0.5000.0 Win32 Version: 1.1.4322.573 CodeBase: file:///c:/windows/assembly/gac/accessibility/1.0.5000.0__b03f5f7f11d50a3a/accessibility.dll ---------------------------------------- System.Xml Assembly Version: 1.0.5000.0 Win32 Version: 1.1.4322.2032 CodeBase: file:///c:/windows/assembly/gac/system.xml/1.0.5000.0__b77a5c561934e089/system.xml.dll ---------------------------------------- ************** JIT Debugging ************** To enable just in time (JIT) debugging, the config file for this application or machine (machine.config) must have the jitDebugging value set in the system.windows.forms section.

Hi Raymond,

I am afraid.Still I couldn''t reproduce this issue.However I have contacted our development team regarding this issue.I will update you later with their feedback.

Hi Joy,

Did you try it with a debugger attached or in debug mode? If so, you might want to try it compiled in release mode.

I appreciate the update.

Thanks.

Raymond.

Hi Raymond,

Thanks for your update.
Could you please try to reproduce this exception after setting DragProvider = Standard?

Please let me know , if you are still getting this exception.

Regards,
Joy

[Joy K George]

Hi Raymond,

We could reproduce the Exception here(GDI+).This exception is raising only in high configuration machines like HT machines.We are currently working on it and will fix this issue as soon as possible.

Thanks for your co-operation.

Joy

Hi Joy,

I''m glad you were able to reproduce the issue.
We are using Hyper-threaded computers here at the office.

Please let me know of any updates.

Thank you.

Raymond.

Has this been fixed? I''m experiencing the same problem.

[Max Hillaert]

I have a Dual Core HT Machine. Probably a thread-safety issue?

[Joy K George]

Hi Max,

We have fixed the issue internally.Please create a Direct-Trac incident to obtain the private patch(required dlls only).
