arrays & strings

[MPrestonf12]

THe result of this is nothing
Im not good at handling strings in array's but from the reference i've looked at this should work. I suspect the problem is in the last parameter of sendmessage, but have tried many combination and nothings worked!!

 num = SendMessage(hwndlist, LB_GETCOUNT, 0, 0);
char buffer[num];
                      for(i=0;i<num; i++){
                                     SendMessage(hwndlist,LB_GETTEXT, i,(LPARAM)buffer[i]);
                                     MessageBox (NULL, buffer , "message", 0);
                                     fputs(buffer, fp);
                                     fprintf(fp, "\n");
                                     }

Thanks for your help.

char only holds a single character, not a string. You'd need something similar to:

num = SendMessage(hwndlist, LB_GETCOUNT, 0, 0);
char *buffer[num];

for(i = 0; i < num; i++) {
    long lLen = SendMessage(hwndlist, LB_GETTEXTLEN, i, 0);
    buffer[i] = new char[lLen+1]; // Include space for terminator
    SendMessage(hwndlist, LB_GETTEXT, i, (LPARAM)buffer[i]);
    MessageBox (NULL, buffer[i], "message", 0);
    fprintf(fp, "%s\n", buffer[i]);
}

for(i = 0; i < num; i++) {
    delete[] buffer[i];
}
