Quick Fix Patches*
=====
DAS1800-850A01.0.0.5
-----
Corrected issues:
- .NET clients would not receive output data from the ActiveX control's array methods. .NET clients can now use the Delphi variant of those methods.
- The DriverLINX ActiveX control's VBArrayBufferXfer method would not work with buffers > 2.
- The DriverLINX ActiveX control's typelibrary has incorrect values for some enumeration constants ( dcFixed, dcBit, etc).
- The DriverLINX ActiveX control would report Method 'VBArrayBufferConvert' of object '_DDlsr' failed when attempting to convert buffers with more 16000 samples from a task with more than 256 channels.
- Upper 32 bits of the count for COUNT64 mode inaccessible from the ActiveX control. Added .Res_Tim_countHi property.
- Constant for OEM gain flag missing from ActiveX API (required to indicate the KPCI3100's dedicated Analog Trigger input). Added DL_CHAN_OEM_FLAG to ActiveX control.
- all the issues corrected in DAS1800-850A01.0.0.4
