That, we do. You forgot to mention the languages like IronPython Smile | :)

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 Smile | :)

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.

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.

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.

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 Smile | :)

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.

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).

Can you open the URL in a webbrowser?

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.

Face Recognition

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.
