Frequently Asked Questions
Q: Can I get technical support during trial period?
A: Of course. High-priority technical support is available by e-mail. Get support now.
Q: My 30-day trial license has expired, can I get an extension to the trial period?
A: Yes, we can extend it for another 30 days. Contact Arction Sales.
Q: Can I distribute LightningChart components royalty-free?
A: Yes. You can distribute LightningChart components with your software free of charge.
Q: I can successfully install and run the SDK examples, but I don't have time to test the features myself in an application like mine. Can you provide a customized sample application or proof-of-concept?
A: Proof-of-concept and custom samples can be negotiated inclusive in LightningChart Ultimate license price.
Q: What is license subscription?
A: License subscription grants license keys, updates and technical support during the subscription period. After the subscription has expired, the components and your software fully work, but a Renewal license purchase is needed to continue receiving updates and using technical support.
Q: Can I upgrade to better edition, for example subscription without source code to subcription with source code?
A: Yes. Upgrading is possible. See the Price list for details, and contact Arction Sales.
Q: LightningChart is perfect for my application, but I would like to have a special feature added.
A: Negotiate customizations with Arction Sales.
Q: Does LightningChart use data point reduction/resampling/decimation/down-sampling when rendering high-speed signals or vast data sets?
A: No, our chart performance is real and we don't use these tricks like our competitors. We don't want to compromise signal quality. All data is stored in the series as it is given to it, and when you start zooming in, you notice all data is really there with full accuracy and quality.
Q: LightningChart is the only suitable data visualization component for our application, but the price is out of our budget. Can we get it with reduced price and without the features we don't need?
A: Features will not be taken away.
Q: What is the secret of LightningChart performance?
A: Hard work, benchmarking and utilizing different technologies. For example, we use Direct3D, custom Intel Math Kernel, HLSL vertex and pixel shaders where they are most efficient.
Q: Why use LightningChart instead of developing our own custom component from scratch?
A: - Saves you incredible amount of time and money. We have developed LightningChart for years, full-time.
A: - Allows your application to be available this year, not after several years.
A: - LightningChart offers performance you most likely wouldn't achieve yourselves.
A: - Saves you from tangling with DirectX, with different level GPUs, and properties of them.
A: - Saves you from tangling with Intel Math Kernel. It is all done already in LightningChart.
Q: ... Yes, but we would like to have our own company name on the libraries, and to sell it as a software component.
A: Get OEM license agreement. Contact Arction Sales.
Q: Can I use LightningChart components in C++ applications (MFC / Win32)?
A: Yes, LightningChart supports Window handle management and the objects can be fully controlled with C++/CLI code. Follow instructions from User's Manual.
Technical troubleshooting FAQ
Q: I drop the LightningChart control on and get error message of missing licenses, or empty license key window.
A: LightningChart needs registry access to HKEY_LOCAL_MACHINE\SOFTWARE to read stored license keys. Run Visual Studio in Administrator rights. Right-click on Visual Studio short-cut, and select "Run as Administrator".
A: LightningChart v.5.1.6 and newer don't need admin rights anymore in Visual Studio.
Q: I'm using LightningChart WPF in Visual Studio 2012. I drop the control on the form and get a license exception. In Visual Studio 2010 it works fine.
A: Install Visual Studio Update 2
Q: ... OK, installed, and it appears fine in the WPF designer. Then I'm running the application from Visual Studio, and get another license exception. Running without debugger works fine.
A: Visual Studio 2012 has a problem in license management when using a hosting process in the debugger. Go to your WPF project's Properties, Debug, and UN-CHECK 'Enable the Visual Studio Hosting Process'.
A: This problem has been cleared in LightningChart v.5.1.6 and newer by getting rid of Microsoft license routines (no need for Licenses.licx anymore).
Q: I drop the LightningChart control on a form and it crashes or looks very strange.
A: Ensure your graphics adapter is at least DirectX 9.0c level and SlimDX runtime is installed.
Q: I'm using a Thread, BackgroundWorker or System.Timers.Timer to update the chart. The chart crashes occasionally in various places, with various error messages.
A: These all use a thread, and it can't update any UI controls safely without synchronizing the call in UI thread.
In WinForms, use this.Invoke(delegate...) or in WPF, use this.Dispatcher.Invoke(delegate...) where 'this' is a Form, Window or parent container.
System.Windows.Forms.Timer and DispatcherTimer are already synchronized as built-in feature and they don't need another Invoke to be used.
Q: I can't uninstall Arction.LightningChartPro from Global assembly cache : Access is denied.
A: Run command prompt with Admin rights (Open Accessories , right-click on Command prompt, select Run with Admin rights). Find gacutil.exe from your hard drive. It's typically in Program files\Microsoft .NET\... Run gacutil /u Arction.LightningChartPro
Q: When I try to use LightningChart in Visual Studio 2010 project, I get error "Code generation for property 'ActiveView' failed. 'Type 'Arction.LightningChartUltimate.ActiveView' is not available in the target framework."
A: You have not selected correct target framework version in your Project - Properties/Options.
If you are using LightningChart Ultimate .NET2 build, select '.NET framework 2' or '.NET framework 3.5'.
If you are using LightningChart Ultimate .NET4 build, select '.NET framework 4'.
Don't select 'Client profile'.
Q: I can't see LightningChart Ultimate components in the Visual Studio Toolbox
A: Toolbox items can be seen in WinForms projects. Set the project's target framework correctly if the components are not shown in Toolbox.
Q: When I try to use LightningChart Ultimate in Visual Studio 2010, it will give error "Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information."
A: Use LightningChart Ultimate .NET4 build instead of .NET2 build. If you still want to use .NET2 build with runtime 4, see Quick Reference for instructions.
Q: When I try to use LightningChart Basic or Pro in Visual Studio 2010, it will give error "Mixed mode assembly is built against version 'v2.0.50727' of the runtime and cannot be loaded in the 4.0 runtime without additional configuration information."
A: When compiling application using LightningChart to target .NET 4.0 framework, a couple of modifications must be done
into two configuration files, as follows:
Your application config file
usually "app.config". It can be found from
your project. If it's not found, add it (Add -> New item ->
Application configuration file), and edit the contents as follows:
<configuration>
<startup
useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime
version="v4.0"/>
</startup>
</configuration>
Visual Studio license compiler config file
Add or modify the application configuration file
for "lc.exe", which is the license compiler for Visual Studio.
Typically, this file exists in "%programfiles%\Microsoft
SDKs\Windows\v7.0A\bin\NETFX 4.0 Tools". Inside this folder, create
a new file called lc.exe.config (or modify the existing file) and
enter the following information:
<?xml version ="1.0"?>
<configuration>
<startup
useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime
version="v4.0"/>
</startup>
</configuration>
