vb.net - Aardvark I2C API with VB causing exception -


i have aardvard i2c/spi dongle (http://www.totalphase.com/products/aardvark-i2cspi/) works great supplied gui. wanted integrate tool own test gui. using ms visual studio express 2013. provide api package vb.net (http://www.totalphase.com/downloads/) contained in aardvark_net.dll. when run example, following error during runtime:

an unhandled exception of type 'system.typeinitializationexception' occurred in windowsapplication1.exe additional information: type initializer 'totalphase.aardvarkapi' threw exception.

it breaks when code tries call aardvarkapi.aa_find_devices() routine.

i created own project, added thr aardvark_net.dll project references, , following code:

imports totalphase public class form1      private sub form1_load(sender object, e eventargs) handles mybase.load         msgbox("detecting aardvark adapters...")         dim num long         dim devices(15) ushort          ' find attached devices         try         num = aardvarkapi.aa_find_devices(16, devices)     catch ex exception         msgbox(ex.message)      end try     end sub end class

same thing, program throws , exceptions @ aardvarkapi.aa_find_devices() , exception message is:

the type initializer 'totalphase.aardvarkapi' threw exception.

i tried going exception settings , unchecking thrown bixes, no change.

i savvy enough created in vb (i not apt @ connectedon other end of aardvark dongle!), use this.

thank you, ~brett

found problem! using api website, have device drivers disk. dated device drivers , went away. (curiously though, example solution still throws exceptions, project not... using same dlls)
