c# - InternetSetCookie returns ERROR_INVALID_OPERATION -


i'm trying expire cookie on machine. when call wininet.dll internetsetcookie returns false , error code 4317 generic error_invalid_operation.

[dllimport("wininet.dll", setlasterror = true)] private static extern bool internetsetcookie(string lpszurlname, string lpszcookiename, string lpszcookiedata);  public void main() {      internetsetcookie("http://example.com","cookiename","somevalue;expires=mon, 01 jan 0001 00:00:00 gmt") }

is there anyway more info on operation invalid?

is there anyway more info on operation invalid?

no there not.

however, getting error_invalid_operation because trying set cookie has been set ( couldn't edit cookie using internetsetcookie() ). had clear cookies using function. need declare first:

[dllimport("wininet.dll", setlasterror = true)] private static extern bool internetsetoption(intptr hinternet,int dwoption,intptr lpbuffer, int lpdwbufferlength);

then can use in following fashion clear cookies ( note 42 internet_option_send_browser_session) :

bool iscleared=internetsetoption(intptr.zero, 42, intptr.zero, 0);
