Thats my code: conHandle = InternetOpen("Test", INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, 0); ... hFile = InternetOpenUrl(conHandle, url.c_str(), NULL, 0, INTERNET_FLAG_RELOAD, 0); ... if (!InternetReadFile(hFile, buffer, maxBufferSize, &size)) { // error } And I also tried to use: InternetOpen("Test", INTERNET_OPEN_TYPE_PROXY, "proxystr", NULL, 0); but without success too. Anyone knows anything about what Im doing wrong? http://stackoverflow.com/questions/521922/internetreadfile-problem-error-87-the-parameter-is-incorrect thankz, erick c++ winapi wininet share|improve this question asked Feb 6 '09 at 19:56 Erick add a comment| 2 Answers 2 active oldest votes up vote 1 down vote You need to keep calling InternetReadFile in a loop until it returns TRUE and the number of bytes read is 0. This usually means at least 2 calls to InternetReadFile. while ( InternetReadFile( hFile, buffer, maxBufferSize, &size ) == FALSE || size > 0 ) { // process buffer contents. // for ex: write the contents of buffer to a temp file for example. } share|improve this answer answered Aug 17 '09 at 10:18 Srikumar 36116 add a comment| up vote 0 down vote It should be: while (InternetReadFile(hFile, buffer, maxBufferSize, &size) == TRUE || size > 0) { // process buffer contents. // for ex: write the contents of buffer to a temp file for example. } share|improve this answer edited Sep 25 '11 at 0:19 LPL 12.1k42149 answered Oct 1 '09 at 10:17 Sumedh 1 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service. asked 7 years ago viewed 2345 times active 5 yea
