    Question Converting ASCII character, to the code that represents it.....?

    hi, here is my code
    Code:
    #include <windows.h>
    #include <stdio.h>
    #define ADDR 0x100AEC4
    
    int main()
    {
    HWND gHwnd;
    DWORD pid;
    HANDLE hProcess;
    
    char result;
    gHwnd = FindWindow(NULL,"********");
    if(!gHwnd)
    {MessageBox(0,"******* could not be detected.","Error",0); return 0;}
    
    GetWindowThreadProcessId(gHwnd,&pid);
    
    hProcess = OpenProcess(PROCESS_ALL_ACCESS,true,pid);
    if(!hProcess)
    {MessageBox(0,"Couldnt get a process handle to SD","Error",0); return 0;}  
    
    ReadProcessMemory(hProcess,(void *)ADDR,(void*)&result,4,NULL);
    //working on getting msgbox to show actual number, not ascii character of the supposed code
    MessageBox(0,(&result),"Warning",MB_OK | MB_ICONWARNING);
    return 0;   
         
    }
    The code works, in that it grabs the value (255) from a memory address, but the messagebox displays it as , the 255th ascii character i believe.

    How can i get it to just display the number?

    Thanks in advance

    Try this.
    Code:
    #include <sstream>
    #include <windows.h>
    //#include <stdio.h>
    #define ADDR 0x100AEC4
    
    int main()
    {
    HWND gHwnd;
    DWORD pid;
    HANDLE hProcess;
    
    char result;
    gHwnd = FindWindow(NULL,"********");
    if(!gHwnd)
    {MessageBox(0,"******* could not be detected.","Error",0); return 0;}
    
    GetWindowThreadProcessId(gHwnd,&pid);
    
    hProcess = OpenProcess(PROCESS_ALL_ACCESS,true,pid);
    if(!hProcess)
    {MessageBox(0,"Couldnt get a process handle to SD","Error",0); return 0;}  
    
    ReadProcessMemory(hProcess,(void *)ADDR,(void*)&result,4,NULL);
    //working on getting msgbox to show actual number, not ascii character of the supposed code
    
       std::ostringstream out;
       out << (unsigned int)(unsigned char) result;
       std::string message = out.str();
    
       MessageBox(0,message.c_str(),"Warning",MB_OK | MB_ICONWARNING);
    
    return 0;   
         
    }

    There's an FAQ entry on the subject: http://faq.cprogramming.com/cgi-bin/...&id=1043284385

    Just use chars instead of ints.
