Dear Diligent AD2 team Please can you update your companies notes supporting Microsoft .net drivers which work with C# and VB.net and F# for the Analog Discovery 2 tool. It is a an excellent tool , but be even more excellent if could work and be used in the microsoft .net environment. This is a link to a previous forum post on the subject which used visual basic 6 from a while back. https://forum.digilentinc.com/topic/3049-vbnet-andor-cnet-wrapper-for-dwfdll/ The original visual basic 6 example . From the time before .net happened https://forum.digilentinc.com/applications/core/interface/file/attachment.php?id=1450 >> 160314_dwf_wrapper.zip I have taken this worked example and updated to get it to run with vb.net in visual studio 2017 .See enclosed attachment- It is failing to work properly due a. dll memory project fault in the .dll driver. The C++ source code for the .dll driver is also included in the attachment. My request is can Digilent fix the driver so that is usable in .net assemblies and is Memory safe . This is the reported run time fault when trying to access FDwfDeviceOpen in vb.net line of code : nRet = FDwfDeviceOpen(-1, hdwf) Fault report : System.AccessViolationException HResult=0x80004003 Message=Attempted to read or write protected memory. This is often an indication that other memory is corrupt. Source=<Cannot evaluate the exception source> StackTrace: <Cannot evaluate the exception stack trace> Thank you for considering this request Digilent_AD2_try2_vb.net.zip
