InternetOpenUrl() problem - why it opens NULL

Hello everyone ! :)

Happy to join you boys and girls :)

I have a C++ (Win32) question for you:
I'm trying to download GIF file from URL and use InternetOpenUrl(); function. After this function call there are no errors and look's it's all OK, but returned handle is NULL. I pass InternetOpen() retuned handle to this function. InternetOpen() handle is also OK, but as I said [i]InternetOpenUrl() returns handle NULL. Have you any ideas on it ? Please help me solve this problem. Thank you.

Here is some code:

Code:

---

hRootHandle = InternetOpen(
  "GIFLinker",
  INTERNET_OPEN_TYPE_PRECONFIG ,
  NULL,NULL,
  INTERNET_FLAG_ASYNC);

hUrlDump = InternetOpenUrl(
  hRootHandle,
  "http://www.algirdas.com/fimg/online-merchants-index.gif",
  NULL, NULL, INTERNET_FLAG_RAW_DATA, 0);


while (GetLastError() == ERROR_IO_PENDING) {
  sprintf(szURL, "Waiting... (%d)",GetLastError());
  SetDlgItemText(prcContext->hWindow, prcContext->nResource,  szURL);
}

// After this code execution:
//  hRootHandle = 0x00cc0004
//  hUrlDump = NULL (0x00000000)
//  GetLastError() = 0 (no errors)

welcome to the boards

here's the way I use the two functions and it seems to work:

Code:

---

  HINTERNET hInternet=NULL;
  hInternet=InternetOpen("agent name",INTERNET_OPEN_TYPE_DIRECT,NULL,NULL,0);
  HINTERNET hOpenURL=InternetOpenUrl(hInternet,strURL,NULL,0, INTERNET_FLAG_DONT_CACHE,0);

Hi ;)

I've tried this:

Code:

---

hINet = InternetOpen("Whatever", INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, 0 );
hFile = InternetOpenUrl(hINet, "http://www.algirdas.com/fimg/online-merchants-index.gif", NULL, 0, 0, 0);

And it seems works !
