Callling .net dll from using CCW

Hi Everyone,

I am using PowerBuilder Classic 12.5 build 2511 and Microsoft Visual Studio 2010.

I followed the steps in the example of Bruce Armstrong about sending an email through SMTP (TeamSybaseCSharp.CSharpSMTP).

In the C# dll project, i used .net framework 3.5. using the socket class to establish a connection with a scale and read the weight.

If i call the dll from a C# winform project works fine and returns the weight, but if i call from PB to the dll returns an empty string.

In my PB code, ConnectToNewObject returns 0 and everything seems ok.

Any suggestions?

Thanks and regards
