#include <string>
#include <sstream>

#pragma comment(lib, "ws2_32.lib")

int main(){

TCHAR hdrs[] = _T("Content-Type: application/x-www-form-urlencoded");
TCHAR frmdata[] = _T("name=John+Doe&userid=hithere&other=P%26Q");
LPCTSTR accept[] = {_T("*/*"), NULL};

HINTERNET hSession = InternetOpen(_T("MyAgent"), INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, 0);
HINTERNET hConnect = InternetConnect(hSession, _T("http://localhost"), INTERNET_DEFAULT_HTTP_PORT, NULL, NULL, INTERNET_SERVICE_HTTP, 0, 1);
HINTERNET hRequest = HttpOpenRequest(hConnect, _T("POST"), _T("/upload.php"), NULL, NULL, accept, 0, 1);
HttpSendRequest(hRequest, hdrs, _tcslen(hdrs), frmdata, _tcslen(frmdata));


return 0;

fwrite($myfile, $txt2);
$txt3 = $other."\n";

Here is a [liker error]. I am using dev c++ for compiling that.

In your c++ code you are not checking the various API function calls for failure.

So, what can I do for removing these errors.

After every call to an API you check for failure. eg for InternetOpen() it returns NULL for failure (https://msdn.microsoft.com/en-us/lib...=vs.85%29.aspx). So you code something like

Code:

---

HINTERNET hSession = InternetOpen(_T("MyAgent"), INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, 0);
if (hSession == NULL) {
    cout << "InternetOpen failure. Error: " << GetLastError() << endl;
    return 1;
}

and similarly for other function calls.
