    How send data to my server?

    Dear sirs,
    I am trying use one code for transfer some data from my C++ dll to my server(website) and return response from server to dll again.
    For example i send one serial number to server and server return another confirmation number to my dll.

    I am using below code and I can read data from my server by BOOL bRead = InternetReadFile(webResult, szwebBuffer, dwBytes, &dwBytesActual);

    i want know how I can send data to my server?
    Which function I can use?

    my code is same below:
    HINTERNET webHANDLE = InternetOpen(strTopic.c_str(), 0, "0", "0", 0);
    HINTERNET webResult = InternetOpenUrlA(webHANDLE, strHttpReq.c_str(), "0", 0, -2080374528, 0);
    if ( webResult )
    {
    char * szwebBuffer[1024];
    memset(szwebBuffer,0,sizeof(szwebBuffer));
    DWORD dwBytes = sizeof(szwebBuffer);
    DWORD dwBytesActual = 0;
    BOOL bRead = InternetReadFile(webResult, szwebBuffer, dwBytes, &dwBytesActual);
    InternetCloseHandle(webResult);
    gpVar->strAccNumber = (char*)szwebBuffer;
    }

    Thanks.

    It will depend on how the page is able to obtain those. For example, the data can be provided as GET parameters passed as a part of the URL.

    Dear Igor,
    Thank you for your response.
    I want send one number to my server.
    So I can send that by this: HINTERNET InternetOpenUrl(
    __in HINTERNET hInternet,
    __in LPCTSTR lpszUrl,
    __in LPCTSTR lpszHeaders,
    __in DWORD dwHeadersLength,
    __in DWORD dwFlags,
    __in DWORD_PTR dwContext
    );

    and using this LPCTSTR lpszHeaders, for sending my number?

    Thanks.

    What is the way the page allows to provide the data? If GET request is okay, lpszUrl will do for your purpose. I kinda repeat myself, don't you find that?
    Best regards,
    Igor
