Hi Gurus,
I need to identify if a network interface card (specifically ethernet) is physical or non-physical?
I use the "NetworkInterface" class to enumerate the network cards. However, in my system there is one LAN adapter that is present and is not physical. This doesnt show up as a virtual adapter also.
Is there any API in .NET which can help to identify if a device is actually present in the machine or not???
Thanks in advance.

I assume you're talking about an adapter in a virtual machine.
I found a utility on the net (with C# source code) that thoroughly examined the WMI database., but I can't remember where or what the name is. If I were you, I would google for "c# wmi" and see what kind of hits I get back. You could then use that utility to explore the networking stuff.

Was this the one? WMI Interface for .NET[^]

Hi John,
Yes the WMI use in .NET has some associated problems.
Is there any other alternative???

Hi John,
I had initially used WMI (system.Management in .net for WMI). But this is not an option because I do not want to use WMI because of issues associated with it.
Do you think, that we have any other alternative?

Hi there,
I know there's no RowDataBound event for the WinForms DataGridView. But there is CellFormatting event in WinForms DataGridView. So Cellformatting event is very very slow.
Is there any solutions like RowDataBound event in WinForms DataGridView (Other then Cellformatting) ?
Thanks for all.

Off the top of my head I do not know of any events like DataRowBound for the WinForms DataGridView.
However, if you were to tell us what it is that you are trying to do, someone might be able to suggest a methodology.

For example;
a cell value is 0 or 1 (its coming database)
If the value is "0" grid should be write "yes" (it doesnt see 0)
If the value is "1" grid should be write "no" (it doesnt see 1)
I hope i was explained it.
Thanks.

If I was doing that I would handle the CellFormatting event, as you mentioned in your original post.
Sorry not to be able to offer better assistance but perhaps someone else will.
Good luck!

If I was doing that I would do it in the datasource and not the data grid. You are not changing the formatting but the content of the cell (I know you don't like the event but it is the one most of us use).

It won't compile. You have syntax errors in CityBuilder (and no, I didn't downvote you - I got the joke).

Let me explain a little of what I'm trying to do....
I have a image of our first and second floor of the build that has each office / cubical shown. Due to this being an inventory application I want to know what is in each one of those. What I am trying to do is when you hover a room with your mouse it highlights it and displays a panel to the right of your cursor showing a list of assets located in that room.
I got a feeling I should be doing this with WPF, but I know nothing about WPF.
My first version I created a panel for each room/cubical and it just displayed the room number.
Is there a way to draw sort of hot spots on a windows form picture box instead of doing panels? I'm wondering if there is a better way of doing this with a Windows Form application

One way to achieve the desired result does not involve 'drawing' at all.
Make use of Control.MouseHover[^]. Of course this means that you would need to have some form of collection containing the coordinates of the various rooms/asset owners to check against the mouse coords.

Here is a technique that often works well:
- have your image, shown to the user;
- have a second image (or a 2D array) of the same size, containing nothing but an item code for each pixel; so it could hold a value of 1 or RGB(1,0,0) for all pixels belonging to room 1, etc.; this "shadow" image is not shown to the user at all.
- have an array or list of items holding the description of each room.
While the mouse hovers the real image, use its (relative) position to do a GetPixel in the shadow image at the same location, that yields the room index (or a special value for none), then fetch the room description from the array/list. You can then:
- paint a highlighted outline of the room on top of the Control that shows the floor plan;
- stuff relevant information in the tooltip.
Remarks:
1. if your image is large, you might create a shadow image at a smaller scale, say 1/4.
2. filling the shadow image can be handled by code, based on the room description; it would then need coordinates of course.

Thanks for the reply!
Ok that sounds like a great idea but I'm having a little difficult time following you. I have not worked much with graphics in that way. Would it be possible to point me to a article I could read that would help in this area?
As to your remarks, my image is large I would say. It's size is 800 x 600.
Edit:
I found an article I think: Image Processing for Dummies with C# and GDI+ Part 1 - Per Pixel Filters[^]
I'm reading it right now.. will let you know if this helps me towards your soltuion

I don't have a link to such thing.
As for size, it basically depends on how accurate you want your hovering response to be; if the walls are 5 pixels thick, then a scale of 1/4 would be adequate. If walls are only 2 pixels, maybe you want actual size.
BTW: the shadow image helps in mapping the mouse position to the room number; you can of course do without, simply by scanning your room list and checking for "room contains point"; the shadow image comes in handy when you have lots of different rooms (performance), or oddly shaped ones (such as corridors) that make the containment test rather tedious.

I posted above on the article I'm reading that will hopefully help with GDI..
As for performance we have rooms of different shape and sizes and there are MANY rooms lol.
