Device which i am working on rs232 serial port

Smal project which given to me is , rs232 serial port monitoring

Data which i am sending through editbox , its should write in hexadecimal n read in a hexadecimal and print as ASCII value ...

byte which u mentioned, i tried write with 0 bytes n read with 0 bytes its working fine

but how do i write Arry bytes in hexadecimal in WriteData() function which i am geting from edibox value

I tried but same issue i am facing

/*.cpp/*
void CUtilitiesTab::OnBnClickedCheck2()
{
int rc;
IPAddr ia;
MessageBeep(1000);
UpdateData(TRUE);
ia = inet_addr(m_ip_address);
rc = NewPing(ia, (ULONG*)&m_hops_count, (ULONG*)&m_rtt);
if (rc == 0)
m_selftestresult.SetWindowTextW(_T("pass"));
else
m_selftestresult.SetWindowTextW(_T("Host not responding or no route, rc = %d", rc));
UpdateData(FALSE);
MessageBeep(1000);
return;

}
int NewPing(IPAddr ia, ULONG* hops_count, ULONG* rtt)
{
boolean IsOk;

IsOk = GetRTTAndHopCount(ia, hops_count, 128, rtt); //the iphlpapi call
if (IsOk == TRUE) return 0;
return GetLastError();
}

/*.h*/

/*Ethernet*/

char m_ip_address[4];
long m_hops_count;

afx_msg void OnBnClickedCheck2();
};

what i tried here.
here i am just declare the IP adress as hardcode , when i click checkbox its should saw the output in edittext like "pass" or "fail"..

but here i am geeting the error

Error C4996 'inet_addr': Use inet_pton() or InetPton() instead or define _WINSOCK_DEPRECATED_NO_WARNINGS to disable deprecated API warnings MGTS

if anyone can help me out this that would be great full

i will come back all the details ,
sample program which i told about below ,,

TY_API_OPEN xApiOpen;
wBoardCountLocal = ApiInit (); /* Local board access */
if ( useServer ) { /* Remote board access */ retVal = ApiConnectToServer(strServerName , &wBoardCountRemote); }
xApiOpen.ul_Module = 0; xApiOpen.ul_Stream = API_STREAM_1; sprintf ( xApiOpen.ac_SrvName, xConfig . acServer );
retVal = ApiOpenEx(&xApiOpen, &ulModHandle );

retVal = ApiClose(boardHandle );
if ( useServer ) ApiDisconnectFromServer(strServerName );
ApiExit ();

"unhandeled exception at 0x6a112efo (msvcr90d.dll) in kgf .exe : 0xc0000005: Access vilotaion reading location 0x8370c29c "
i geting this error

Thank you soo much , Cpallini
its works

no operator "+=" matches these operands

const unsigned char nbuf[] = { 'A', 'B', '\0', '\0', 'C', 'd', 'e', 'f' };

above the programs , vice virsa ...
I am trying with same way i didnt get if any changes let me know

Expecting output will be "65 66 0 0 67 100 101 102"

Thank you soo much its works ,this just demo programs this way i need implement in serial monitoring ,thanks once again

i am sorry i am not able to make understand you guys , i am new in developers filed ,
lets again i will try to explain , for Example

CString msg;
char nbuf = 67

msg.Format(L"%c", (BYTE)nbuf);

m_asciiresult.SetWindowTextW(msg);
above the program i am geting output C (67 ascii value character is "C") , Now what i want is array format . the ascci value are in ,
char nbuf[]={67,68,69} ,this i want character 67=C,68=D,69=E ,it means the want output is "CDE" either above the program i doing correct or wrong please make it help ,i hope i make you understand ...thank you

CString msg;
wchar_t nbuf[] = L"ABC";
msg.Format(L"%d", nbuf);
m_asciiresult.SetWindowTextW(msg);
even i try this one it was like character to change the integer but this also i did not get proper out i am geting dummy value ....

I hope you understand my questions,

Here i am talking about conversions ...
for exmple
char nbuf[10] = {67,68,69,70,70,72};
msg.Format(L"%c", (BYTE)nbuf[0]);

m_asciiresult.SetWindowTextW(msg);
i am geting output for this "C" but i want the output something like "CDEF"..but i doing correct or wrong above code but i want help

i starting from the basic ,my requirement is my data is come from hardware based in ASCII format ,Above the code i want to print in static text in mfc ,how do i do that

m_result_ascii ///variable of static text

Above code is character to ASCII value ,(WHICH is did code based on that)
which i mentioned ASCII code convert to character (my expected).

TRACE( "ASCII format is : %c\n", myByte ); //solutions 2 it help me out in mfc to get character

Thanks , i will try this

Yeh something wrong is there ,no any idea

u help me to modified the code which i tried to print ASCII character ..

for (int i = 0; i < 122; i++){
int asciiVal = rand()%97 + 122;
char asciiChar = asciiVal;
cout << asciiChar << " ";
}
Above the progrmas i getting error ,i want to print character value "a" to "z" and dumbed into static text in mfc

BOOL CAsciidemoDlg::OnInitDialog()
{
CDialogEx::OnInitDialog();

// Add "About..." menu item to system menu.

// IDM_ABOUTBOX must be in the system command range.
ASSERT((IDM_ABOUTBOX & 0xFFF0) == IDM_ABOUTBOX);
ASSERT(IDM_ABOUTBOX < 0xF000);

CMenu* pSysMenu = GetSystemMenu(FALSE);
if (pSysMenu != nullptr)
{
BOOL bNameValid;
CString strAboutMenu;
bNameValid = strAboutMenu.LoadString(IDS_ABOUTBOX);
ASSERT(bNameValid);
if (!strAboutMenu.IsEmpty())
{
pSysMenu->AppendMenu(MF_SEPARATOR);
pSysMenu->AppendMenu(MF_STRING, IDM_ABOUTBOX, strAboutMenu);
}
}

// Set the icon for this dialog. The framework does this automatically
// when the application's main window is not a dialog
SetIcon(m_hIcon, TRUE); // Set big icon
SetIcon(m_hIcon, FALSE); // Set small icon

char nchar = 65;
m_ASCIIRESULT = nchar; /** here i want to dumbed the data which i will get the
output in cout.
// TODO: Add extra initialization here

return TRUE; // return TRUE unless you set the focus to a control
}

Thanks ,lets try and i will update once when i complete

Thank you Richard Macutchan

Yes ,i got the output what i expected through the solutions 3

For serial port Monitoring ,while monitoring the port i should work with main window

Thank you so much its help me lot
and its working fine while copying code
i am new here and learning programming ,you guys are really helpful
Thank you once again
