Connection with remote computer

I want to write a program that checks the status of remote machines continuously whether they are on or off. Which method i should use

@Ian: I agree. You could easily implement a multi-cast (or similar) heartbeat solution if you control the machines and can ensure the heartbeat is running via a scheduler or other means.
But if you simply want to write a standalone program to check other machines without installing software on them, I could see that being more problematic. You might be able to come up with an O/S specific solution or assume certain programs are always installed. But there are problems in each of those methodologies, IMO.

How can i get my printer to connect with my computer to print?

I have a HP photosmart prem-web C309n-s printer. I have two different computers. One is a 4 year old HP laptop, and I just recently purchased an HP touchsmart 320 PC. I installed the printer when I first got this computer, and the printing worked fine from any computer that was in the house. Now, it seems that my printer is not connected with my computer. With my dad's laptop in the house, he had before installed the printer, and when I look up the network on my printer, the only computer that it shows connection with is his. I need to print things for class, and I'm not sure how to make my desktop "visible" to my printer. Please help!!!!

In the Print dialog box choose "Scale To Fit"

As long as the apps and ibooks are still available in the store, and you use the same iTunes account as you originally used to buy them, then you should be able to re-download them for free : http://support.apple.com/kb/HT2519

Using different credetial to connect to remote computer to get Cert information

I am using following function to get cert details from remote computers. How do I change it to accept credentials to connect to remote computer?
PS : Remote computers are windows 2003 computers without PowerShell installed on it.
function Get-Cert( $computer=$env:computername ){ $ro=[System.Security.Cryptography.X509Certificates.OpenFlags]"ReadOnly" $lm=[System.Security.Cryptography.X509Certificates.StoreLocation]"LocalMachine" $store=new-object System.Security.Cryptography.X509Certificates.X509Store("\\$computer\my",$lm) $store.Open($ro) $store.Certificates}Get-Cert ServerA
-Edatha-

Certainly. Here's a quick example that uses the PowerShell registry provider as a quick an easy way to enumerate the subkeys of HKLM\Software\Microsoft\SystemCertificates\MY\Certificates\ , and to read the Blob value as a byte array. In your
case, you'd probably want to look into using something like WMI's StdRegProv class to accomplish the same thing.
Once you have the byte array, just pass it to the constructor of X509Certificate2. (Note the unary comma in that constructor call; we're binding an object to the -ArgumentList parameter of New-Object, and when you're calling constructors that take
a single array argument, you need the comma.)
Get-ChildItem HKLM:\SOFTWARE\Microsoft\SystemCertificates\MY\Certificates |
ForEach-Object {
$byteArray = (Get-ItemProperty -Path $_.PSPath -Name Blob).Blob
$certificate = New-Object System.Security.Cryptography.X509Certificates.X509Certificate2(,$byteArray)
$certificate

I don't want other computers connect with my computer, I don't want sharing my macbook pro, so how I can protect my computer and avoid other people connect with my computers

As long as you do not enable Sharing of any kind (System Preferences > Sharing) no other computer can connect with yours. Also make sure you have your wireless network protected with a WPA2 password.
That's all I can suggest without knowing what OS version you are running (you are not running iOS as that is for iDevices).

Any suggestions on how to get wifi to work? I have a multitech router and can connect with a computer wirelessly but not the ipad.

My iPhone won't connect with my computer or charge. How can I fix this?

My iPhone won't connect with my computer. It also will not charge. I changed the white charging cord, but I have the same problem. I connected other devices to the USB and they work. It's strictly the iPhone.
How can I correct this?

I forgot to mention, the iPhone does charge via wall plug.

Connecting to Remote Computer

Does Mac have the capability to connect to a Windows based remote computer? For example, I'm planning on purchasing a MacBook Pro soon and I need to know if I will be able to connect remotely to my office computer which is Windows based.
Any help would be great.

The answer depends. Can you currently connect using another computer today?
If you can, then you should be able to connect with your Mac.
Microsoft offers Remote Desktop Connection client for Mac OS X
<http://www.microsoft.com/mac/otherproducts/otherproducts.aspx?pid=remotedesktop client>
You can use a Mac VNC client, such as Chicken of the VNC, to connect to a VNC server on your Windows system, such as TightVNC.
LogMeIn.com allows remotely connecting to PCs from Macs via a browser such as Safari. You would have to run the LogMeIn server on your PC.
There are other services that allow you to connect Macs and PC over the internet.
However, many times computers systems at work are behind firewalls that block incoming connections. Companies that do allow remote access often times require the use of VPN software. Depending on the VPN being used, there may or may not be a Mac client. My company uses a Cisco VPN server and provides employees with the Mac Cisco VPN client.

JDBC connect from remote computer fails

Hi all,
I have successfully installed the XE server and I can connect over JDBC from clients running locally on the machine where the XE server is installed.
However when I try to connect from a remote computer using the same client I get an error saying: The Network Adapter could not establish the connection
I can ping the machine with XE installed and all firewalls on the machines are turned off.
Any ideas on the subject of JDBC remote connect to XE server? Or is it simply that it is not supported?
Appreciate all the help I can get.
Thanks,
/Anders

On my machine I have the listener bound to local interface.
Listener.ora has hostname in it, and this is the listener status:
As status shows the hostname is resolved to localhost, on this machine I am unable (with this configuration) to share the db to other machines (I do not have oracle client on my other pc, but telnet is unable to connect to port 1521).
Changing hostname to ipaddres solves.

When I connect with my computer, I see the I-phone in I-tunes, but not in Windows Explorer?

I connect my I-phone with my computer. In I-tunes the phone is there, but not s a removable device in Windows Explorer. It should be recognised I assume. Who knows the answer? Thanks in advance.
Arend from Holland

So what sync settings do you currently have enabled from under the iPod's Summary and Music tabs? Any error messages when you try to sync?
To be sure, reset sync warnings. To do this, right->click the iPod under Devices and choose Reset Warnings. Then resync your iPod.
