numbers to strings
How would i have a Message box display a number returned from a function?
i.e.
MessageBox(0, GetNum(), 0,0);
i tryed putting (LPCSTR)GetNum() but that didn't work... any ideas?
You'd have to specifically convert it yourself. One way is to do it like this (but likely many people are going to bug about it):

char szBuffer[512];sprintf( szBuffer, "The number was %d.", GetNum() );MessageBox( szBuffer, "Caption goes here", MB_OK );

You can use either sprintf() or a string stream.
sprintf() is the C-way of doing this. If you are programming in C++ I suggest you to use string stream instead of sprintf().
with sprintf()
with string streams
This question is probably in the top 5 FAQ. It might be a good idea to browse the forum before asking such simple question.
HTH,

with sprintf()
// a 32 bit integer contains at most 9 digits, the sign -,// and we need some room for the '\0'char buf[11]; sprintf(buf, "%d", myInteger);MessageBox(0, buf, 0,0);
with string streams
#include <sstream>std::string getNum(int myInteger){ std::stringstream myStream; myStream << myInteger << std::ends; return myStream.str();}MessageBox(0, getNum(myInteger).c_str(), 0, 0);

HTH,
Using the c++ way is much safer.
Just a note on naming of functions: getNum(int) is terribly named.
Sorry, but I hate reading code like that. Name a function for what it does:
numToString(int)
