InternetOpenUrl

[Petar Popara]

InternetOpenUrl sends GET request? Where can I see server response? In
my case InternetOpenUrl fails and GetLastError() returns 0.

Hello
You can use debug build of WinInet to see what is happening.

my case InternetOpenUrl fails and GetLastError() returns 0.

What I do in one of my applications is to call HttpQueryInfo if
InternetOpenUrl fails. That returns back the header information associated
with an HTTP server request. Details here:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wininet/wininet/httpqueryinfo.asp.
Be aware that this makes its own request to the server, so its not quite the
same as seeing the server response to InternetOpenUrl but it may be close
enough.

In addition to what Brian Combs asks, I recommend that both Petar and Brian
Cryer try to simplify their code. In the process, they may find the problem.
If not, post the simplified code.

Good advice - IF the problem lies with the code.

I first looked into this because I knew that occasionally the problem would
lie with the server (or at least I would understand the nature of the
problem from the server response) - I was working on a link checker at the
time.

There are times when there is a genuine requirement to see the server
response.

There may or may not be a problem with the code. I would like to eliminate
that possibility by examining the code.

If you think it's the server that's doing it, you could telnet on port 80 to
the server, send HTTP commands and view the response.

Here is an Adobe KB article about it, although I have to say it is kind of
lame. I am suprised it doesn't say "try standing on your head".

You'll note that one of the implications is that it could be a server
problem (but I really don't think so). You'll also note that there are
suggestions for both upgrading Acrobat Reader and Internet Explorer. This
implies that they fixed something that is related, but they are too lame to
say what.

Sorry, this has nothing to do with it. I meant to post this to an IIS
newsgroup and got mixed up :(

Please disregard!!!
