HTTP cant make a tcp connection to a webserver but can through browser????

Re: HTTP cant make a tcp connection to a webserver but can through browser????

1-Sep-02 12:23

I took a look at the HTTP example on codeproject that explains the GET and POST command:
http://www.codeproject.com/internet/HTTPGet-Post.asp

Now, i thought i understood perfectly well what was going on, when you type in a url in your browser it connects via tcp to that server and sends a header to that server to retrieve a page.
Now there's this site http://www.proximus-interactive.be of our mobile operator, just a commercial site like any other. But spooky enough, i wrote an application that tries to connect to port 80 on www.proximus-interactive.be and it wont connect!! but when i surf there in my browser it works fine... doesn't that mean my browser connects to it..on port 80? cause its the default.. and i noticed other sites do the same thing, and its really bugging me. If anyone knows whats causing this please explain.

Thank you very much in advance.

P.S.: i can connect to a bunch of other sites just fine, so its not me :p

See if you can connect using Chris' WebGrab[^] sample. It's possible that the server may be refusing your connection based on the agent name.

no thats not it, maybe proxy related?

Hi, The webgrab sample you directed me to used the CInternetSession class to do all the connection things itself, there is no code in the Webgrab sample that actually shows the connection being made, it just uses functions from CInternetSession. And the Agent cannot be the problem because i simply cant connect to the server, i cant even send the agent! Frown | :(

But now i was thinking, i use a proxy server, maybe it has something to with that? maybe do i just need to connect to my proxy and post the request there??? or how does that work??

Thank you for your reply and help.

I tried this from the command prompt

telnet www.proximus-interactive.be 80
GET / HTTP/1.1
Host: blah

and it goes into some weird character mode. I've never seen that either.

I'm using Visual C++.NET to do some low level stuff - direct file access, etc. - that I can't do in Visual C#.NET but forms and controls are very tedious hard labor at that level. Is there a way I could use the visual aspects of C#.NET to draw forms and controls and then use them in visual C++.NET?

I don't see why not, provided you create a managed application that produces a winexe. I've not done it myself, but this language interoperability is something MS has been really pushing.

Of course, you can always do it the other way round also. You ought to be able to create an assembly which wraps unmanaged code and then use this assembly from a C# project, thus create the UI etc. in C# which uses types exposed in the C++.NET assembly.

Again, I've not done it but it would probably be better to produce a UI application in C# that uses a C++ assembly, as opposed to a C++ application which uses a C# assembly to display forms etc. You can probably do it both ways, but the latter is probably less of a head trip Smile | :)

If you need more help let me know and I'll fire up my VS.NET and give it a try.

VC++ release exe - how to add symbols?

nss1-Sep-02 10:22

Apparently you can debug the release version of the project just like the debug version if you add symbols. How to do this?

Thanks,

In VC6 go to Project Settings, in C/C++ page select Debug Info: Program Database and in Link page check Generate debug info.

Okay Thanks.

Another problem....I have the debug version going and when I run it to the breakpoint it brings up a dialog asking where the pdb file is.....mfc42.pdb....

Whats this? It never did this before....

Pavel Klocek1-Sep-02 10:51

I've never encountered this. The pdb files (program database) contain debug informations for programs and libraries. By me is the mfc42.pdb file is installed in system directory WinNT\System32.

Something's wrong if your debug version is linking with mfc42.dll. It should be using mfc42d.dll, so check your linker settings.

Color a form

I'm working on a small database as an exercise to give to my friends and family. This is just to help me learn a little database programming and thought it would help me learn more to add extra functionality to the form.
I've tried and can't figure out how to color the form. I'd like to add a set of buttons (which I've done) that will allow the user to pick the color of the form background.
I'd appreciate any guidence on this.

Thanks

Hello,
You use the term "form", can you be more specific as to what kind of MFC Object you are referring to?

Maybe this might help:

COLORREF SetBkColor(<br />
  HDC hdc,           // handle to DC<br />
  COLORREF crColor   // background color value<br />
);

usage:

<br />
CPaintDC dc(this); // device context for painting<br />
COLORREF crText;<br />
crText = RGB(128,128,255);<br />
dc.SetBkColor(crText);

I'm sorry. I should have been more specific.
I am building an ODBC database. The form naturally is the user interface where the fields are.

Thanks a lot for your time.

Michael Dunn1-Sep-02 10:14

(Just a note for the future, when you say "form", C++ programmers probably won't understand what you mean. The term to use is "dialog" or "CFormView" if you're using that MFC class.)

Thank you Mike, I appreciate your guidence. I'm obviously real new here and I want to learn everything....naturally, there is always a little more to learn than I thought.
Have you got any thoughts on how I can make my CFormView different colors? Can I just make calls to OnPaint like in a CDialog class? I found an example for what I want to do but it's in a CDialogBox; would this be the same except of course for the names?

Thanks
Garry

Michael Dunn1-Sep-02 11:05

OnEraseBkgnd() is the function to use. See the VC Forum FAQ (link at the top of the page), there's a FAQ about this topic. (I think it applies, I've not used CFormView much but I think the view behaves just like a dialog.)
