I do not understand. If you know the server's IP, you can connect it directly without considering the router.

In fact, I use router at home and I could ping other PC successfully. So check the configuration of the router. Maybe that's the real problem.

I sincerely hope those aren't real ip's.
Never post any real data on forums, you never know who is going to see them.

As to your problem.
If you are within the network then you don't need your router.

If not you will probably need to authenticate yourself with the router after which you can then log on to the server.
Or you can set your router to forward requests using remote desktop port (is a specific one but don't remember it right now) to the server.
Then you can connect using the routers ip (or a dyndns address).

Well the servers admin should give you a username / password to enter when surfing to a url or ip. Once you'v done this you then should be able to go to the server. But this all has to be configured on the router (don't ask me how, I'v never done the configuration myself but your admin should know).
I'm shure there are other ways to do this but this is the one we use at my workplace.

No matter how you do it you'll have to be able to make configuration changes to the router, if you can't do that I don't think it's possible.

Hello,
As per your help, i have make router configurations for port forwarding. It works fine, I connect to server. But from the server side i cant able to send maesssages to clients. Is there any configuration is needed for outgoing messages?
Please help me for that.
Thank you in advance.

You'll have to check if the router/firewall allows outgoing messages. (normally it should)

Can the server connect to the client?
Its possible that the clients router/firewall blocks these or that you have to do the same configuration changes as you did with the servers router.
If the client is directly connected to the internet check the pc's firewall settings. (maybe disable it for a moment and check if it works then)

I need to change the cursor to my own design.
For eg:
ms paint, if the user select a pen, the cursor will change to pen.

I need those cursors used in paint. From where i get those cursor, other than the default cursors. From where i can download it?

Regards,

I do not know where to download the icons, however, you can use some tools to achieve the icons, such as Photoshop.

In Visual Studio 2008...

Right click your project in solution explorer
choose add/new item - select cursor file
edit the cursor the way you want it - also set its hot spot
right click on the cursor file in solution explorer
choose properties and set build action to embedded resource

To load your cursor, assuming you're using forms

this.Cursor = new Cursor(GetType(), "Cursor1.cur");

where "this" is a Form/Control class.

Ohhh (s)he needs the cursors.

I don't know why I assume people want to do their own development...

Never mind then. Smile | :)

p.s. In my defense, maybe I answered what was going to be his/her next question Poke tongue | ;-P

Apparently I didn't answer your question.

You can also probably extract cursors right out of an app's EXE or DLL(s).
I'll leave the copyright infringement issues to you...

Visual studio comes with a bunch of ready-to-use cursors as well.

Getting unique key

hii
I am generating key based on cpu id using following code
public static string GetProcessorID()
{
string sProcessorID = "";
string sQuery = "SELECT ProcessorId FROM Win32_Processor";
ManagementObjectSearcher oManagementObjectSearcher = new ManagementObjectSearcher(sQuery );
ManagementObjectCollection oCollection = oManagementObjectSearcher.Get();
foreach(ManagementObject oManagementObject in oCollection )
{
sProcessorID = (string)oManagementObject["ProcessorId"];
}

return (sProcessorID);
}

But i find that the generated id is not unique.
is there any other way to generate unique id based on cpu?
as i want to secure my software from piracy

thanks in advance

Have you had a look at GUID's..? They are unique (some even use them as database primary keys Smile | :)

)

To generate one :

Guid guid = new Guid();

guid = Guid.NewGuid();

string unique = guid.ToString();

A dogged, arrogant belief in self and the childlike idealism that comes with not knowing my limits. This is my greatest blessing, my priceless attribute.

If you need a unique number that is always the same when regenerated, you can always ask a hashcode on a unique string, as long as you manage to create the same string. Here is a modified version of the previous answer to illustrate the idea:

Guid guid = new Guid();
guid = Guid.NewGuid();
string unique = guid.ToString();
int uniqueInt = unique.GetHashCode();

GUID represents a globally unique identifier. So do not worry.

Every time it generate a new id. i don't want this

i want a unique id for a particular pc
so that it don't match with the id of other computer

Dragonfly_Lee5-Jan-09 2:45

I see, in this case, you can use the MAC address as the unique ID for PC. Of cource, you can also generate the license file through MD5. Everytime the app runs, check the license file firstly.
