"An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 25 - Connection string is not valid)"

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3) J#, outdated language, no further progess at all, less and less people use it?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.

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.
