Tee chart direct2d issue , gives red cross in the form.

[Saumil]

Hello,

I have made a sample demo project to explain.

I am just adding random values in the fastline series.



once the plotting starts , I hit ctrl , alt , delete and try to open the task manager. and graph disappear and I get red cross in the graph.



The error is related to d2d, if i don't use direct2d then it runs without any issue.
Error log is attached. and sample project too.


The error is
SlimDX.Direct2D.Direct2DException: D2DERR_RECREATE_TARGET: here has been a presentation error that may be recoverable. The caller needs to recreate, rerender the entire frame, and reattempt present. (-2003238900)

Hello Saumil,

Ok seems the problem is your infinite loop. I have changed your loop for a timer with interval=1 and your problem doesn't appear:

Code: Select all

        private Timer timer; 
       public void FileExitItemClick(System.Object Sender, System.EventArgs _e1)
        {
            this.Close();
        }

        public void FormCreate(System.Object Sender, System.EventArgs _e1)
        {
            Chart1.Aspect.View3D = false;
            Chart1.Walls.View3D = false;
            timer = new Timer(); 
            Chart1.Panel.Gradient.Visible = false;
            Chart1.Panel.Color = System.Drawing.SystemColors.ButtonFace;
            Chart1.Header.Text.Remove(0);            
            Chart1.Header.Text.Insert(0, "");
            timer.Start();
            timer.Interval = 1; 
            timer.Tick +=timer_Tick;
        }
        void timer_Tick(object sender, EventArgs e)
        {
          Random abc = new Random();
          Series1.Add(abc.NextDouble(), "", Color.Blue);
          Series1.RefreshSeries();
          Series1.Repaint();
          Chart1.Refresh();
        }

Could you tell us if previous code help you to solve your problem? Remember adjusts your timer as you like.

Thanks,

Sandra,

I am using the code you posted. I still get the red X.

if I comment this line , Chart1.Graphics3D = new Graphics3DDirect2D(Chart1.Chart);
then it works fine , i don't get this error.

Also , the error only appears when
1. I use direct2d in the project
2. I open task manager through ctrl, alt, delete and through the screen below.



a normal user would open task manager through ctrl alt delete and We need to direct2d in the project for performance.
I have recorded the screen , please check .

Sandra,

I just checked with Teechart Direct2D Demo. It also shows he red x.

GDI + Canvas runs fine, Direct2D canvas throws error.

Hello Saumil,

Your problem is very strange and its reproduction is very complicate, but we can reproduce it finally, with your code, our code and demo. Therefore, I have added your request in bug list report with number [TD29016645]. We will try to fix it for next maintenance releases of TeeChartForDirect2D.

Thanks,

[Saumil]

Sandra , the issue is not solved in the latest release.

We need a fix soon, is there any alternate solution I can perform?

D2D demo shipped with latest release also gives me a red cross just like i posted earlier.

Hello Saumil,

Sandra , the issue is not solved in the latest release.

The time we need to fix the bugs depends of some variables such as the complexity of the problem, the number of issues with even higher priority that claims our team attention. I recommend you to be aware at this forum, our RSS news feed, twitter and facebook accounts for new release announcements and what's implemented on them.

We need a fix soon, is there any alternate solution I can perform?
D2D demo shipped with latest release also gives me a red cross just like i posted earlier.

In both cases I can only recommend you in the moment, try to avoid the situation for example, doesn't do Ctrl+Alt+Supr. In the case you want open task manager, you can do click with right button in the bottom task bar and open the task manager.

Thanks,
