DVL Library and VB.NET

[davide_mercanti2]

Hi to all.

With SDK VEA SDK2.3 i'm trying to set up a demo program.

In some PC (VMWARE example virtual machine ) I get an error saying... (see below).

Could be an OpenGL / Video driver problem ? In these machines the VEV application runs with software renderer mode.

Is it possible also with DVL libraries ?

Follow Igor's advice to modify locale first, if the exception still happens, please provide the value of two parameters you use to call ParseDouble() function

[davide_mercanti2]

Hi Bo.

I can't provide you the parameters, the exceptions fires during the

"_dvlCore.InitRenderer"

and this is the last line of log that i can write to the file...

Hi to all.

Some news ?

Same problem also with the SDK 2.4

[igor_afanasyev]

Hi Davide,

The DVL Library does not implement software rendering. It supports only OpenGL.

Most likely your VMWare machine does not have VMWare Tools installed which provides support for hardware accelerated OpenGL 3.

As for FormatException - try to change the current locale when the application starts.

Imports System.Globalization

Imports System.Threading

Thread.CurrentThread.CurrentCulture = New CultureInfo("en-US")

[davide_mercanti2]

Thank Igor.

I suppose the problem is something related to the VMWare settings.

I've changed the locale (as your suggestion), check for VMWare tools (installed) but the exception still remains.

I've checked with OpenGL Extension Viewer 4.4.

It says OpenGL 1.1...
