"Invalid parameter used" being thrown from 'TextRe

[Adrian]

I've just installed the latest build 2.9.2489.20950 and am occasionally getting the following message

"Property accessor 'TextRenderingHint' on object 'System.Drawing.Graphics' threw the following exception: 'Invalid parameter used.'

the error is throws from the following line,

Code: Select all

tc.Export.Template.Save(memstream)

I'm catching it, and if I retry the operation a few times it works...

Hi Adrian,

Could you please send us a simple example project we can run "as-is" to reproduce the problem here?

You can post your files at news://www.steema.net/steema.public.attachments newsgroup.

Thanks in advance.

[Adrian]

Sorry Narcis,

I can't reproduce it today... I did have some problems with my dev environment yesterday... it was probably related to that. I'll get back to you it it occurs again.

Cheers..

[Adrian]

It's back again...

It can be reproduced using your Teechart for dotnet examples application. I searched for BAR and opened the BAR example, then EDIT and EXPORT then NATIVE, INCLUDE SERIES DATA and click on FILE SIZE... the following error is thrown which is the same as I'm getting in my application when I call

Code: Select all

tc.Export.Template.Save(memstream)

I don't get it every time however and if I do if I reexecute the same code generally it works second time around...

[Narcís]

Hi Adrian,

Thanks for the information. I could reproduce the problem here and added it (TF02011886) to our defect list to be fixed for future releases.

[Jan Madsen]

Hi Narcis

Do you know when it will be fixed?

[Narcís]

Hi Michael,

I'm afraid I can't tell you when it will be fixed for now. Please be aware at this forum for new releases announcements and what's being implemented/fixed on each release.

[Adrian]

Hi Narcis,
I appreciate that it's difficult to give an exact date when a bug will be fixed, however this problem is an absolute show stopper for the next release of my application.

With it present the saving of charts is too unreliable so I'm essentially waiting now for an update from you or a suitable workaround.

thanks..

[Adrian]

A little more information about this problem. I backed out the latest Tchart build and reinstalled version 2.0.2489.20950. This fixed the problem, however while making some other changes to my system it re-occured with build 2.0.2489.20950.

As far as I can see if at any stage during the life of the TChart component I set the parent form enabled to FALSE the component will throw this error when trying to save to a memory stream. I don't know if this is a actual cause but it's interesting all the same.

[Narcís]

Hi Adrian,

Thanks for the information but I can not reproduce the problem here using latest TeeChart maintenance release and the code below. Could you please modify it so that we can reproduce the problem here?

Code: Select all

		private void Form1_Load(object sender, EventArgs e)
		{
			bar1.FillSampleValues();
		}

		private MemoryStream stream;

		private void button1_Click(object sender, EventArgs e)
		{
			this.Enabled = false;

			stream = new MemoryStream();			
			tChart1.Export.Template.Save(stream);

			//tChart1.Clear();
		}

		private void button2_Click(object sender, EventArgs e)
		{
			stream.Position = 0;
			tChart1.Import.Template.Load(stream);
		}

Regarding the FileSize issue, we can no longer reproduce this with our current sources. This is most likely because of some changes we made in exporting routines for other issues. Those changes are included with Build 2.0.2511.18117 from 16th November. Could you please test if it works fine at your end with that release?

Thanks in advance.

[Mont]

Narcis,

I've just posted in http://www.teechart.net/support/viewtopic.php?t=5082

I think this is the same problem - the export dialog does work occasionally (without doing anything differently), but I get the error more times than not.

Cheers,

Mike

[Adrian]

This problem is still present using the 2.0.2511.18117 build and the supplied demo... see my post above for how to replicate it.


IT REALLY NEEDS TO BE FIXED URGENTLY!!!!

************** 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.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the machine
rather than being handled by this dialog.

[Adrian]

I don't know whether this is related but there seems to be another problem that happens when calling the following, though it doesn't happen all the time.

Code: Select all

'  break point 1
tc.Export.Template.Save(memstream)
m_chart.m_bTeeData = memstream.ToArray
'  break point 2
memstream.Close()

I have a line series that has colormember = "" at breakpoint 1 above, after the SAVE the colormember = "Colors"

At breakpoint 1
tc.series(0).colormember "" String

At break point 2
tc.series(0).colormember "Colors" String

There is definately something screwey with tc.Export.Template.Save(memstream)

Hello everyone,

We have just posted a new maintenance release at the client area which includes a fix for TF02011886.
