Hello Network for DevC++

there should be absolutely no difference between code written for visual studio and code that works in Dev-C++. Generally VS6.0 sucks chunks so you have to use some retarded (but valid) syntax to get things working; but it should play nice in DevC++

My guess is that you didn't set your project up correctly: you aren't #include'ing the correct files, or linking to the correct libraries.

Post your compiler or linker errors.

I'm typing from work right now on lunch break (I'm an office manager by day, coder by night), therefore, I don't have the compiler comments infront of me. I was doing the ConnectText in Chapter 4 out of the GameDev.net networking book.

I replaced all the NULL with '\0' and that cleared up all the errors.

But the linker errors were all related to the ws2_32.lib file which was not any where to be found. I spent all night looking on the net for it, and the only place I could find the file it's self was in VS2005. I can't get the VS2005 freebie thing from MS because I don't have the right operating system so it refused to extract it's self.

Home now, and here is what the linker has to say:

Did you remember to link to ws2_32.lib?

Edit: just read your earlier post saying you couldn't find the lib. It should be included in the Platform SDK if you don't already have it.

I don't have that library, it's a library for VS6.0 which is needed for the sample code from chapter 4, first code example from "GameDev.net Multiplayer Game Programming" which is where the tutorial came from. I don't have VS6.0, I've got GameDevC++ and ws2_32.lib is no where in my system and I can't find it for download on the net.

I need to find DevC++ Network code samples. Or advice to replace that library with one I've got.

Dev-C++ should provide its own version of the Winsock2 library called libws2_32.a. Try linking to that.

OMG OMG OMG!
That works! thank you!!!
