ChartEditor crash on Themes tab click

[georgez]

The ChartEditor with 3.5.3105.20152 crashes the app immediately when the Themes tab is clicked.

Workaround is to hide the unneccesary tab.

Possible related information: The computers used are NOT connected to the internet.

Hi georgez,

I'm not able to reproduce the issue here. It works fine even unplugging the computer from the internet. Are there any specific steps we should follow to reproduce the issue here?

Thanks in advance.

[georgez]

Thanks for your response. There is not much to tell you. We make a form with TeeCommander and TeeChart, populate one or more series from a DataTable source, click the ChartEditor button, click the Themes tab - crash.
(BTW - not a newbie - been using TeeChart since Delphi2.)

Hi georgez,

Thanks for the information. That's what I tried here and couldn't reproduce the issue using this code:

Code: Select all

		public Form1()
		{
			InitializeComponent();
			InitializeChart();		
		}

		private void InitializeChart()
		{
			Steema.TeeChart.Styles.Bar bar1 = new Steema.TeeChart.Styles.Bar(tChart1.Chart);
			bar1.Clear();
			bar1.DataSource = CreateDataSet();
			bar1.YValues.DataMember = "SALARY";
			bar1.XValues.DataMember = "ID";
			bar1.LabelMember = "LASTNAME";

			bar1.CheckDataSource(); 
		}

		private DataTable CreateDataSet()
		{
			DataTable Employee = new DataTable();

			DataColumn SALARY = new DataColumn("SALARY", Type.GetType("System.Int32"));
			DataColumn ID = new DataColumn("ID", Type.GetType("System.Int32"));
			DataColumn LASTNAME = new DataColumn("LASTNAME", Type.GetType("System.String"));

			Employee.Columns.Add(SALARY);
			Employee.Columns.Add(ID);
			Employee.Columns.Add(LASTNAME);

			DataRow dataRow;
			
			dataRow = Employee.NewRow();
			dataRow[SALARY] = 10000;
			dataRow[ID] = 1;
			dataRow[LASTNAME] = "Jones";

			Employee.Rows.Add(dataRow);

			dataRow = Employee.NewRow();
			dataRow[SALARY] = 12000;
			dataRow[ID] = 2;
			dataRow[LASTNAME] = "Smith";

			Employee.Rows.Add(dataRow);

			dataRow = Employee.NewRow();
			dataRow[SALARY] = 9000;
			dataRow[ID] = 3;
			dataRow[LASTNAME] = "Johnson";

			Employee.Rows.Add(dataRow);

			return Employee;
		} 

Could you please modify it or send us a simple example project so that we can reproduce the problem here?

Thanks in advance.

I created a new project, added teechart.dll to the references, added a tChart1 to the form, substituted your code and did a build. Then, each time the pre-built app was started it took 10 seconds to appear. (Dual Pentium, 2.8Ghz, 2GB)

[georgez]

Sorry about the previous post - I got my bug reports mixed up.

Your code does not mention Editor or Themes. Are they supposed to be included?

[georgez]

Hi Narcis,

Here is the complete answer to your suggestion:

I created a new project,
added teechart.dll to the references,
added a tChart1 to the form,
added a editor1 to the form,
set the editor1.Chart property to tChart1,
substituted your code,
added a doubleclick method to tChart1 to ShowEditor,
and did a build.

Then, each time the pre-built app was started it took 10 seconds to appear. (Dual Pentium, 2.8Ghz, 2GB)

Next, I doubleclicked the chart to show the editor,
clicked the Themes tab,
and it CRASHED.

All of the following is information from the exception:

"Access to the path is denied.

System.Collections.ListDictionaryInternal.NodeKeyValueCollection

System.IO.FileSystemInfo.set_Attributes at Steema.TeeChart.Editors.ThemeEditor.AddCustomThemes"

I hope this is what you need.
Regards,
george

Hi george,

Thanks for the information and sorry if my reply wasn't clear enough. I was using a ChartController instead of an editor. Anyway, using this code:

Code: Select all

		public Form1()
		{
			InitializeComponent();
			InitializeChart();		
		}

		private Steema.TeeChart.Editor editor1;

		private void InitializeChart()
		{
			Steema.TeeChart.Styles.Bar bar1 = new Steema.TeeChart.Styles.Bar(tChart1.Chart);
			bar1.Clear();
			bar1.DataSource = CreateDataSet();
			bar1.YValues.DataMember = "SALARY";
			bar1.XValues.DataMember = "ID";
			bar1.LabelMember = "LASTNAME";

			bar1.CheckDataSource();

			editor1 = new Steema.TeeChart.Editor(tChart1);

			tChart1.DoubleClick += new EventHandler(tChart1_DoubleClick);
		}

		void tChart1_DoubleClick(object sender, EventArgs e)
		{
			editor1.ShowModal();
		}

		private DataTable CreateDataSet()
		{
			DataTable Employee = new DataTable();

			DataColumn SALARY = new DataColumn("SALARY", Type.GetType("System.Int32"));
			DataColumn ID = new DataColumn("ID", Type.GetType("System.Int32"));
			DataColumn LASTNAME = new DataColumn("LASTNAME", Type.GetType("System.String"));

			Employee.Columns.Add(SALARY);
			Employee.Columns.Add(ID);
			Employee.Columns.Add(LASTNAME);

			DataRow dataRow;
			
			dataRow = Employee.NewRow();
			dataRow[SALARY] = 10000;
			dataRow[ID] = 1;
			dataRow[LASTNAME] = "Jones";

			Employee.Rows.Add(dataRow);

			dataRow = Employee.NewRow();
			dataRow[SALARY] = 12000;
			dataRow[ID] = 2;
			dataRow[LASTNAME] = "Smith";

			Employee.Rows.Add(dataRow);

			dataRow = Employee.NewRow();
			dataRow[SALARY] = 9000;
			dataRow[ID] = 3;
			dataRow[LASTNAME] = "Johnson";

			Employee.Rows.Add(dataRow);

			return Employee;
		} 

I'm not able to reproduce the issue here either building the application in debug or release mode. How are you building it?

BTW: I'm using an Intel Core 2 Quad 6600 machine with 4GB RAM.

[georgez]

Narcis,

You still didn't mention clicking the Themes tab.

I went through the entire exercise again using your new code.

The result is: clicking the Themes tab crashes in either debug or release.

Hello,

The result is: clicking the Themes tab crashes in either debug or release.

In your particular case, this may be true. Are you using Custom Themes? The stack trace certainly suggests you are. The method AddCustomThemes() only sets the FileSystemInfo.Attributes property if the path specified in the ThemeFolder value within the TeeChart registry key exists (which it doesn't after a default installation) and this folder contains *.xml files. You can check the registry value by navigating to the following registry key using Start -> Run -> regedit:
HKEY_LOCAL_MACHINE\SOFTWARE\Steema Software\TeeChart.NET

Please check that the path specified in the ThemeFolder value exists on your machine and that it contains *.xml files. If you do not need these files for your application, the easiest solution would be to delete the ThemeFolder registry value from the above mentioned key. If you do need these files then we will need to work out why setting the FileSystemInfo.Attributes property on them throws an exception.

[georgez]

Are you using Custom Themes? The stack trace certainly suggests you are.

We are using NO themes. Whatever exists is exactly as placed there by your downloaded installer.

I see. Ok, in which case you may like to follow my previous suggestion and delete the ThemeFolder value from within the TeeChart registry key.

[georgez]

Thanks for your help Christopher and Narcis. Since not everyone has Registry access, we will continue with our initial workaround.
