The error message indicates that the issue is with establishing a connection, not with authenticating a connection.

I want IE to navigate through a PDF file which is on desktop when a PDF file's URL is obtained in the addressbar,
object empty = System.Reflection.Missing.Value;
webBrowser.Navigate(DesktopFilePath, ref empty, ref empty, ref empty, ref empty);
if I continuously open some url's like http://somesite.pdf, then the IE continuously navigates through the PDF file which
is on desktop(i.e., c:\currentUser\desktop\123.pdf), after sometime if I try to navigate some other links IE gets hanged,
How can I solve this?
I was doing all this through a BHO, when a DocumentComplete Event is fired using c#.

We know that so far there are several .net languages included in Visual Studio.
But what are the advantages and disadvantages of these languages, compared to each other?
I have the following personal feelings, but I am not sure whether they are right or not, if not, please correct me:
1) C++, still the most performance efficient, but no more features and no more improvement(?)., especially MFC is just stopped, MFC has no future(?).
2) C#, most standard language in .net framework, most elegant langauges learned from several old languages incuding C, C++ and Java, more and more features and improvements are coming, c# 1.0, 2.0, 3.0, 4.0 ...
3) J#, outdated language, no further progess at all, less and less people use it? it will die or already died?
4) VB.net, traditional MS language, will be (hopefully) co-developed with C#
5) F#, functional language, a new .net language with more functional supports,but many features in C# and F# can be seen from each other, F# can be popular just as C#?
In considering the applications of web appications, C# seems to be most promising language.
therefore, it is necessary to learn C# very well, other languages may be a plus to some extend.
wellcome your comments.

Yeah, I agree with you in some points. But I think the area of uses for C++ is completely different as compared to C#.net,VB.net,J#.net etc.

This almost reads like a homework question.

That, we do. You forgot to mention the languages like IronPython 
Seraph_summer wrote: 1) C++, still the most performance efficient, but no more features and no more improvement(?)., especially MFC is just stopped, MFC has no future(?).
There are some slight differences between C++ and C++.NET, and you could call that an improvement. As a sidenote, C++ isn't limited to MFC and definitely has a future.

"Most elegant" is a personal flavor and not relevant in an objective comparison
Seraph_summer wrote: 4) VB.net, traditional MS language, will be (hopefully) co-developed with C#
I think that VB.NET will be merged with C#, sooner or later.
Seraph_summer wrote: 5) F#, functional language, a new .net language with more functional supports,but many features in C# and F# can be seen from each other, F# can be popular just as C#?
Lots of features can be "seen from each other", since the .NET framework is shared across the languages. F# isn't meant as a replacement for C#, and I doubt that many people will try to convert VB6-projects to F#. It is, however, a cool calculus-language.

If you only consider webapplications, C# will be a good choice (like PHP). C++ isn't really meant for webapplications, although there's nothing stopping you from mixing languages. You may also want to take a look at some scripting languages, like JavaScript

 Hi,
I m quering about how will I get the appropriate row record on clicking respective checkbox on the row of datagridview? Is there any event about databinding events to succeed further? I m using c# windows & I have attached checkbox to each row programmatically.
I want to check it for furher process. Here my data is displaying on textchange event of textbox using LIKE query.
Please help.

IMO all you need to do is add a unbound DataGridViewCheckBoxColumn to the gridview and handle the CellContentClick event.

Hi Guys,
i have the need to find an application that is similiar to OWA but has an addon,
OWA does not ALERT a new mail when you are not on the web page open, so i thought to code an application that functions as mini Outlook / OWA, but alerts like outlook near the taskbar or any alert on the tray,
how hard could it be to code such a thing in c# or is there anything similiar ?
Thanks

OWA runs as a webpage, and webpages cannot create tray-icons; they can only display things in the browser that they are displayed in.

That's not what i asked,

i need to code smt simple that alert new mails in the tray and play sound i choose

OWA Notifier is a desktop-application. You can drop a NotifyIcon[^] on it to display an icon in the tray. The webpage won't raise any events, but you can use a timer[^] to fetch the webpage (with a given interval).

Hello All,
I hope someone can help. I have a dataGridView populated with data, I have added a dataGridViewComboBoxColumn. The dataGridViewComboBoxColumn is populated per row. That all works great. The issue I am having is getting the value of a dataGridViewComboBoxColumn Cell.
The last thing I tired is:
DataGridViewComboBoxCell cell = dataGridView1[cntR, cntC] as DataGridViewComboBoxCell;
string val = cell.ValueMember.ToString();
string val2 = cell.Value.ToString();
Which always returns "" for both.
Any help would really be great.

I have been looking for a way to preform facial recognition with C#.
I have searched and searched for a library or control for such a task.
I could only find one... "ActiveFace" but activeface.net is just a blank page and all the download sites i can find redirect me to the blank site.
Does anyone know of any control or library for preforming face recognition with C#?

That's a really complex task, don't expect anything good, for free.

Indeed it is very complex. I dont expect there to be any library or control for free. But I cannot find any libraries, even ones you have to pay for.
