need help changing win32 project to MFC

[beginner123]

i have a client tcp program is win32 that reads a list of ip addresses from a web host and then displays the addresses in a listbox but i want to use a previous MFC file i created for this application. but i am having difficultly changing the code from the win32 program into the MFC program.

here is the win32 code:

typedef unsigned long	U32;
typedef unsigned short	U16;
typedef unsigned short	U8;

typedef signed long		S32;
typedef signed short	S16;
typedef signed short	S8;

using namespace std;

class splitstring : public string {
    vector<string> flds;
public:
    splitstring(const char *s) : string(s) { };
    vector<string>& split(char delim, int rep=0);
};

// split: receives a char delimiter; returns a vector of strings
// By default ignores repeated delimiters, unless argument rep == 1.
vector<string>& splitstring::split(char delim, int rep) {
    if (!flds.empty()) flds.clear();  // empty vector if necessary
    string work = data();
    string buf = "";
    int i = 0;
    while (i < work.length()) {
        if (work[i] != delim)
            buf += work[i];
        else if (rep == 1) {
            flds.push_back(buf);
            buf = "";
        } else if (buf.length() > 0) {
            flds.push_back(buf);
            buf = "";
        }

    }

can some please help me with this code?

i don't really know what win32 code should go into the main thread of the MFC project. also how to push the ip address into the listbox

[modoran]

You should avoid MFC if the code you have so far already works, it only will confuses you as a beginner.

Instead get rid of MFC parts and port it to win32 api:
1 get rid of AfxMessageBox -> use MessageBox instead
2 as for Mutex and CriticalSection classes use CreateMutex, OpenMutex, ReleaseMutex and InitializeCriticalSection, EnterCriticalSection, LeaveCriticalSection APIs directly, you hopefully will understand how things works.
3 do not use CreateThread, use _beginthreadex() instead.
