The message lists all the values it is trying to use to connect. So it is reasonably safe to assume that one or more of them is not correct. That is the only information you have to work with, so you need to investigate further to discover which one it is.

ic... maybe i was thought it got an error while posting...

Yes, but that has nothing to do with your question.

It depends on what you are trying to learn. If you know C++ then Win32 should be fairly easy. But if you do not know C++ then that is what you need to start with. Here is a starter for C++: Learn C++[^] And one for Windows: EFNet #Winprog[^]

You are welcome.

No. Using the Console to interface with the user is "old fashioned" and you won't be doing it for long anyway. C# was born into a Windows world, and was primarily designed to work in Windows apps. C++ was the child of C, and was born into a world where Windows was new and unpopular, so it was given much more text based user input focus, because it needed it way back then. In the modern world, even C++ apps very rarely use cin at all now! "I have no idea what I did, but I'm taking full credit for it." - ThisOldTony AntiTwitter: @DalekDave is now a follower!

WIN32 API any framework including MFC just adds another layer of abstraction and the issue that the frameworks itself often becomes incompatible with newer windows versions. There is already a growing list of bugs with MFC and Windows 10. Conceptually if you want a C++ objectification of the Win32 API then an old framework called Win32++ is still around it does nothing other than take the standard Win32 API into objects it doesn't mess around with the message system like MFC and is completely opensource. It also doesn't have the problems with .NET integration that MFC has.

You can guess where MS is going with this (MS hasn't announced any frameworks but some public test ones have appeared GitHub - kpocza/LoWe: Linux on Windows extender[^]) :-) One company has already hit the WSL space hard https://www.whitewaterfoundry.com/[^] In vino veritas

ok, thx for yer info

Are you completely tired of doing your own research? Experimenting? Exploring? Because that's what I've been trying to get you to do. Because, without these qualities, you're going to find it very difficult to grow in the field of writing code. Have a nice life.
