Get the status of computer on lan

Posted By:      Posted Date: October 15, 2010    Points: 0   Category :.NET Framework


I am making a program using Visual Studio 2010 to get information of a computer on local area network. I have put timer on ping to check if it is on the network. Also i can get my user and domain name using Environment.I can not figure out how to further check if the computer is logged on or if it is free? If i can find user name of the local computer then may be i can show it is being used or if any other suggestions more then welcome. Thanks

I am using following code:

Dim pingsender As New Ping

  Dim HostName As String

  'For x = 1 To 3

  For i = 0 To 9

   HostName = "CN0809B2-DW061" + i.ToString '+ x.ToString

   If pingsender.Send(HostName).Status = IPStatus.Success Then

    txtPingResult.Text += String.Format("Reply from: " & HostName & vbCrLf)

How to transfer files between computer and mobile device using bluetooth

What is Bluetooth? How can I have it on my computer?

Bluetooth wireless technology is a communication technology that allows two devices to communicate wirelessly. Most of the notebooks are nowadays equipped with bluetooth. For those notebooks or computers that don't, you can use a bluetooth dongle to add the functionality and it just costs you around $5. Although higher price range bluetooth dongles are available but it makes no sense of buying them if you just plan to connect your mobile device to the computer. Look for one that has Bluetooth v2.0 + EDR (Enhance Data Rate) supporting speeds of upto 3Mbps and with Vista support. You can easily have one of that kind in just $5.

Setting up bluetooth to work on your computer

Just Insert the bluetooth dongle in the USB.
It should get detected by your Operating System and should be ready to use. In case it is just detected as a new hardware, you need to install drivers for it that came with your bluetooth dongle (You can try Google to find the drivers).
Once drivers are installed, a bluetooth notification icon will appear in your system tray.
Right Click on it to access Settings (This may vary with your bluetooth dongle).
Make sure you have turned Discovery On (It allow others to see your computer).
Switch On the bluetooth on the mobile device.

Trying to launch a .exe file on my local computer from intranet site.


I have been told I can launch a local program on my PC from my intranet site but it has to be done with Active X or vbscript and not javascript.  I found the following little sample html code that will launch notepad.  However, I cannot figure out how to put this in a button, etc., within my aspx or code behind to execute it.  Does anybody have any idea how to do this?  I have a lot of javascript code I am launching urls with and I have even tried using that but again, I have been told that to do it client side it needs to be vbscript or something like this.  Any ideas?

Redirect to Security Questions if Site accessed from unrecognized computer?


I'm fairly new to ASP.NET and i'm using the Membership Provider.  I have the need to do similar to some banking sites. Baically I need to track "authorized" computers/ip's for a user.  If the user accesses the site form a recognized Computer/IP then the user is allowed into the app after successful login.  If the computer/IP is not recognized I need to redirect them to a screen to answer the security question setup in fhte Membership Provider.

Has anyone done anything like this or can anyone point me to any examples?  I did a search, but can't seem to find anything.

My idea is to maintain a list of authorized computers/IP addresses and check them on initial login.  If the IP address isn't found I can redirect them to the questions.  My concern is that they are then actually authenticated and could enter any of the site URL's as an authenticated user.

Any suggestions greatly appreciated. 

How to make the Workflow Status remain "In Progress" when a task is "Rejected"


Hi Sir/Mam,

I have a work flow running on a list, when a task is Rejected at a stage then the Workflow status is set to "Completed". Instead of this I want the Status to remain as "In Progress", so that in future after the modification of the document the Approver may Approve it and then take it to the next stages. This is not possible if the Workflow is set to "Completed".

Can you please suggest an easy way to do this

Thanks in Advance


Change the Workflow Status through code


HI Folks,

I have a scenario where i need to develop a 6 stage approval workflow(sequential) using WWF and depoly it to sharepoint. Everythigns fine till here.

Now we look ahead to change the Status field on the documents library which actually has the Workflow Name as the column name and its value being In Progress, depending on the stage of approval. Like(Approved 1, Approved 2, Approved 3.)

And if rejected the status should be rejected than Completed. Any idea how can we update this column of the List item.

I have tried item[workflowProperties.Workflow.ParentAssociation.Name]="Approved 1";

But this throws an error saying input string is not in a correct format.

Any information would be of great help :)

Anonymous Web Site receives "The request failed with HTTP status 401: Unauthorized"


I set up a test website on my local box and was able to access sharepoint search using the querySearch web service from SP.  After I got it all working properly I transferred the code to the target website that is set up with anonymous access for all people on the fab floor.  However from this website I keep getting the 401 error.  It can't be SP because the same code worked from my local website "localhost".  Any suggestions?  we don't want to have to have the fab people log in so we can't not have the box anonymous.  I would appreciate any suggestions very much!!!

Status "Installing" keeps stuck

Hi All..

I have a problem about status that is stucked.. I've read many forums that related to my problem, but still can't solved it yet :(

Here is my problem...

After 3 months I keep on uploading, removing, and uploading form, I have no problem.. Until today, when I want to upload my form, the status keeps on "Installing", instead of "Ready".
Then I removed my form using Timer Job Definitions, and I delete form.wsp. It works.
Afterwards, I try to upload form again, I have the same problem with stuck status. And then I delete again using same way.
I've tried more than 10 times, and the result still the same one.

Things that I've tried are:
- Reset IIS.
- Reset Application Pool.
- Check the services (e.g: Windows Sharepoint Services Administration, Search, Timer, Tracing) -- all are already started.
- Use "stsadm -o execadmsvcjobs"
- Reset Infopath Form ID
- Publish and change Infopath Form Name
- Command "net start SPTimerV3" and "net start SPAdmin"

Tried all things above, but still can't work. Status is still stuck.

Then, I try to upload other forms, but still have the same problem.

Please help me. I'm stuck already... :((

Is there anything I can do again?


How to remove a saved password from a users computer


Hi, I have an asp.net website that requires users to login using their Active Directory credentials. All users of the website have AD accounts. Some of the users are at remote locations and share a common computer login (I know this is not recommended but it is what it is, I have no say in that). Every so often a user will log into my website and click the Remember Passwod box which causes the next person that comes along to not be prompted to log in. All users are on IE 7.  I have tried having them go into tools and deleting the cookies, saved passwords, etc but when they go to my website they are still not being prompted to log in. I have recently migrated to IIS 7 and I understand there is a way to have the user enter the site through a custom form but I have not gotten that far yet. How can I make sure the users password is removed from IE? Thanks for any help.
