Use sprintf to get char* from the int.
Code: [Select]
char buffer[10];
int hey = 55;

sprintf(buffer, "%d", hey);
MessageBox(hwnd, buffer, "This program is:", MB_OK | MB_ICONINFORMATION);

Hello elektrik1000,

You simply have to convert you number to char.

Code: [Select]
#include <windows.h>
#include <stdio.h>

int main(void) {
  int key;
  char s[10];
 
  // You can do it like this
  key = 55;
  _itoa(key, s, 10);
  MessageBox(0, s, "Convert Int to Char", MB_ICONINFORMATION);

  // Or like that
  key = 212;
  wsprintf(s, "%d", key);
  MessageBox(0, s, "Convert Int to Char", MB_ICONINFORMATION);

  return 0;
}
