Tcp exception only on target

[illishar]

Hello,

I'm trying to build some small tcp communication. It's based on the samples from here: http://beijerinc.com/support/ix/forum/v ... p?f=9&t=73


My sample works just fine, when tested on the PC. But when I upload it to target, it throws the following exception:

"An unknown, invalid, or unsupported option or level was specified in a getsockopt or setsockopt call".

I'm using the exact same calls as in the samples. What am I doing wrong? My target is a T7A and I'm using the newest version of iX Developer.

Most of our HMIs use WinCE, which has only a subset of C# functions that the full C# has. You may be using a function that is in the full .NET C# libraries but not in the WinCE version. I would need to see your project as well as know what HMI you are targeting before I could suggest any possible solutions to your issue.
