Simple console input here[^].
The funniest thing about this particular signature is that by the time you realise it doesn't say anything it's too late to stop reading it.

Take a look at some of the articles here on CodeProject, there is certain to be something that will help you.
Just say 'NO' to evaluated arguments for diadic functions! Ash

Try it out on google.
In google search bar try
"DataGridView + <here>"
replace here with your every point and you will get answer of your every point.

A DataGridView is not an appropriate interface for data input -- create a form for that.

Consider the NETWORK_SERVICE:
SecurityIdentifier ns = new SecurityIdentifier(WellKnownSidType.NetworkServiceSid, null);
What is the SID for IIS_IUSRS account?

You should be able to get it with:
SecurityIdentifier iusers = new SecurityIdentifier("S-1-5-32-568");
|
|
|
|

Is there a WellKnownSidType. constant for it available?

AFAIK, there are no constants defined anywhere that contain all the wellknown SIDs. However, you can write your own using the data from here[^].

In the world of ActiveX/COM, the singleton pattern could hardly be implemented: COM requires a public constructor without parameters.
Now I have some third party components which actually should be singletons, as I can see from their behavior. E.g. one of them has an "Initialize" method which crashes when called a second time with a "Reinitialize Error" (and gladly no "Initialized" property, which is a bug which should be fixed by that third party).
In order to work with these components, I decided to write some C# wrapper classes where I could implement the singleton pattern correctly and add some nice features. I did that for one class manually, and it was a real lot of work: write all the functions, properties, and events, and just forward them to the internal COM object.
Since I'd like to create such wrappers for several more classes, I am interested in a tool which could create at least some function stubs. What can you recommend here? Anything which reduces manual work is appreciated.

Maybe write a utility that will generate the code?

With Reflection being our friend, that task did not seem too terrifying. But there are lots of caveats: methods for adding/removing event handlers will show up, also the get/set accessors of properties show up as methods, and sometimes a special property "is not supported by the language", and so on... Some manual polishing is still required.

someone plz suggest a library to receive live video through a camera(not an IP camera).
|
|
|
|
|
That is totally dependent on the hardware you choose to take in the video.
What hardware you using, how is the live content being connected e.g. usb, firewire, analog.....

basically i m using a 2.4 ghz analog transmitter for video transmission and a receiver plus a tv card at the receiving end which i think should work the same way as a digital camera.

Look at Icon.ToBitmap in MSDN
Real men don't use instructions. They are only the manufacturers opinion on how to put the thing together.

It does not help, and i have tried that
Cannot implicitly convert type 'System.Drawing.Bitmap' to 'System.Windows.Controls.Image'
|

You are going to have to ask that one in the WPF forum!

I Thing i got a hand of it. I was pretty sure it was a type. But it is a control. I got confused with normal Image class.
it was the folowing code for solution
using ImageIcon = System.Drawing.Icon;
Extract Icon from exe and then converts
ImageIcon ico = ImageIcon.ExtractAssociatedIcon(dpi.LongFileName);
Bitmap bmp = ico.ToBitmap();
MemoryStream stream = new MemoryStream();
bmp.Save(stream, System.Drawing.Imaging.ImageFormat.Png);
BitmapImage bmpImage = new BitmapImage();
bmpImage.BeginInit();
stream.Seek(0, SeekOrigin.Begin);
bmpImage.StreamSource = stream;
bmpImage.EndInit();
dpi.FileIcon = new System.Windows.Controls.Image();
dpi.FileIcon.Source = bmpImage;

Sorry - it doesn't work for him.
His is WPF System.Windows.Controls.Image, not a System.Windows.Drawing.Image.

Wow! That's a lot of work! The last time I made an icon (or converted it back to something else) I just changed the extension from .bmp to .ico (or back again). Why does each new release make everything harder?

Actualy i am using WPF (Windows Presentation Framework). And Code Beehind is C#. I am used of windows form programing, so i assumed that Image class is same as windows Form, but it was actualy a control. Since i wanted to show in datagrid I shoud it store as BitmapImage not image class, and then use xaml to use that BitmapImage. So this conversion is totaly useless for me (Again, I thought it isn't a control), however it may help someone.
