Ok, Thank's for these informations.
Do you have a date for the new service pack?

Hi, we have implemented the import of Visio stencils from streams. This functionality will be introduced in the upcoming service pack of Nevron Diagram for .NET.

Regarding the not properly imported stencils, please note that the Nevron Visio importer does not fully support all Visio shape types and features. Take a look at this documentation topic for more information about the limitations of the Visio Importer.

Best Regards,
Nevron Support Team

Hi, is there any way to import visio stencils (.vsx) from a memory stream?
The only function I saw from the NVisioImporter is "import", but this one does not provide a way to import from memory stream...
The only way to use the import function is with a filename.

Also, some of the stencils I've imported from a vsx file are not properly loaded... The shape is empty or some parts of the shape are missing.
Is there a solution to this bug?
