Error on MarvinViewControl

Hallo,

i try to use the MarvinViewControl for .NET 4. 

I have molfile strings which i use to show on the MarvinViewControl. The problem is that i always get the following error in the control:

"The type initializer for 'chemaxon.marvin.paint.internal.ColorCollection' threw an exception".

Can anyone help me?

 Hi,

 

Which version of JChem .NET API do you use? You can download the latest version from here:

http://www.chemaxon.com/download/jchem/jchem-for-net/

 

Could you send us a code snippet for reproducing the problem?

 

Thank you,

Hi,

I use the version 6.1.2.2.

If i use it in an empty winforms solution, it works. In my project i always get this error. Could there be a problem with infragistics?

Hi,

Please make sure, that all the JChem.NET assemblies are available when you run your project.

Also be aware, that .NET Compact Framework, and .NET 4 Client Profile are not supported.

The officialy supported framework version is .NET 3.5 (, though it might run on .NET 4 full profile).

Hi,

I created a new application with .NET4 and Infragistics and all works. I also tried to generate a picture with the molecule renderer and got the error, too.

Hi,

Could you post the code that causes the error?

The exact same code, on the exact same machine works when you try it within a WinForms application?

Hi,

I use this code:

StructureDrawingInfo drawingInfo = new StructureDrawingInfo(new Size(width, height));

JChemMolecule molecule = new JChemMolecule(new MoleculeData(molfile, MoleculeFormat.Unknown));

molecule.CheckNull("molecule").Renderer.Settings = new JChemMoleculeRenderingSettings(drawingInfo);

Image moleculeImage = molecule.Renderer.RenderToImage(ImageFormat.Png);

This code works on another winforms application on the same machine with the same framework.

This works for me with even a Console Application.

What is the project type ('output type' in project properties) where it doesn't work?

A.

Hi,

it's an Windows Application.

I use this code in a user control and want to fill a picture box. Even if i use the MarvinViewControl and fill it with a molfile i get the same error.

I tried the same in the blank windows application and there all works.

Hi,

I downloaded a trial version of  NetAdvantage_Ultimate2013 library.

Created a WinForms .NET 4 application.

Added an UltraButton from the Infragistics control library, and added the code above to the Click event handler.

It works without any problem.

I suspect there is some kind of configuration problem in your project.

Could you send us a basic demo project which we can reproduce the problem?

A.

Hi,

i found the problem. I have to replace isentris controls with chemaxon controls. And if i have the references for isentris (MDL) and the chemaxon references in the project, it doesn't work. If i delete the MDL references, it works.

I'm glad to hear that.
