Re: .NET WebRequest + Webclient V's WinInet - C# Discussion Boards

12-Feb-03 11:39

Okay,

I've got two apps.

1) in C++ using WinInet.
2) in C# using WebRequest

When requesting the same URL in each I get a diffenent page of HTML returned.

The C++ version is fine, but the C# version is not.

It seems to stem from the fact that the site is saying its and unsuported browser from the C# app!!!! I get the same undisired result in the browser Opera.

So, does anyone know what provides the same functionality as WinInet from .NET?

I was thinking maybe I should not be using Webrequest, but Webclient, but I get the same result. I'm guessing that something in the header of the .NET implementation is not there, or disimmilar to Internet Explorer.

Use System.Net.HttpWebRequest instead and set your UserAgent string to match your PC's browser.

Thanks. I'll give it a try.

You don't know what IE6's UserAgent string is like to you?

I know its somthing like - Mozilla4.0(compatible, IE6) bla bla bla.

Thanks,

No still not having it. The CHttpConnection set of classes in MFC work fine for the url, but HttpWebRequest is not working even why I apply the User-Agent to the header.

Here it is:

The .NET classes return a different page, to IE.

As I said the WinInet library returns the same page as IE. If you want to test it quickly Chris has built page grabber class in this article : http://www.codeproject.com/internet/webgrab.asp[^]

It uses the MFC http classes which I'm right in thinking use WinInet. Also the VB Internet Transfer control correctly pulls down the page.

Thanks,

Giles

This appears to be happening because of a javascript redirect within the HTML. I'm not sure how WinInet or the VB transfer control handles that. Both HttpWebRequest and WebClient gave the same results. Not the one you are looking for though Dead | X|

It could be a frames issue as well.

Enumerating files (FindFirstFile)

15-Feb-03 0:40

I don't think its the Java script, as what it redirect to is the same. It could be the frames, but I don't see what its trying to pull out.

I need to enumerate all the files in a folder, but I can't see how to do this in C#.
In C++ I would just use FindFirstFile(), but I can't find any functions that does that in C#, only a sample about interop/marshalling that shpws how to use the FindFirstFile API.

Is it really true that there is'nt any functions/classes to do that in the .NET framework/C#? Confused | :confused:

Take a look at the System.IO.Directory & DirectoryInfo.

Also there is File and FileInfo.

I think you make use of the members of the xInfo class.

e.g.

DirectoryInfo dir = new DirectoryInfo(Directory.GetCurrentDirectory());

Console.WriteLine(dir.FullName);

foreach(FileInfo f in dir.GetFiles())
{
    Console.WriteLine("{0} - {1}", f.Name, f.Length)
}

This seems like a pain, but you get used to it.

For a seriously handy class look at System.IO.Path and its static members. Evrey thing you ever needed for manipulation a file path.
