Type casting ??

This seemingly very simple thing is escaping my grasp. I want to put an INT into a messagebox (windows API) which will only take char pointer. Ok, I think: "type cast" and do the following:

Code:

---

#include <windows.h>

int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance, PSTR szCmdLine, int iCmdShow) {
        int imyint;

        char chMychar;
       
        imyint = 20;

        chMychar = (char) imyint;

        MessageBox (NULL, &chMychar, "Test", MB_OK);

        return (0);
}

---

(NOTE: That is not my exact code. Its something very very similar I just made up at school here, the real code is at my house. I'll edit it in later if it makes a differance. Oh and the compiler im using is MinGW under WindowsXP)

Ok so I complie and execute that code, and I get the message box with some weird looking ASCII contents, instead of the the number 20.

Thank you for any help you can provide!

It expects a pointer value. By casting 20 you've told it to print the string at that memory location which is, obviously, junk :)

To make it into a string:

Code:

---

#include <windows.h>

int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance, PSTR szCmdLine, int iCmdShow) {
        int myint = 20;
        char buf[40];
        snprintf(buf, 40, "My int: %d", myint);

        MessageBox(NULL, buf, "Test", MB_OK);

        return 0;
}
