   Hello, good news!!!

   I just figured out what was missing in what was reported in previous comment.

   In the Properties Pages of the .NET project, choosing "Configuration Properties" on the left panel, and then "Build", there is a switch labelled "Register for COM Interop", and of course it has to be set "ON", for all this to work as expected!!!!

   Well, let's keep working.!!!!

   Be well!!!!!

   Hello, G.Gnana Arun:

   Hi, good day, greetings from Mexico City.

   Well, this post is to commet I just tried your implementation, I created a .NET DLL with VB.NET, then followed the .TLB file, just as you specify in your article, but at the moment of using the library in a VB 6.0 project, using the reference to the .TLB file, as you dictate, just when the object is to be instantiated, I receive a Num 429 error, "ActiveX Object can´t be created". I include here the code for the class in VB.NET:

   Public

   Class cDotNetUtilsVB60

   Public Shared Function IsPositiveInfinity(ByVal pdblNum As Double) As Boolean

   Dim lnuNumTem As Double

   Return lnuNumTem.IsPositiveInfinity(pdblNum)

   End Function

   Public Shared Function IsNegativeInfinity(ByVal pdblNum As Double) As Boolean

   Dim lnuNumTem As Double

   Return lnuNumTem.IsNegativeInfinity(pdblNum)

   End Function

   End

   Class

   Can you figure out what I'm doing wrong???????

   Thanks in advance, be well

   Roberto Gutierrez R.
