This is the second question today about something that can easily be found in the documentation or on the web (search for "c# format binary string" and "c# copy part of array" to get the solutions as the first hit). You really should learn how to use google and MSDN Library, and save your forum posts until you need them. 
Despite everything, the person most likely to be fooling you next is yourself.

In my application I have hooked the keyboard.Global hooked and in one function im getting a error saying..
“Attempted to read or write protected memory. This is often an indication that other memory is corrupt.”
It comes from this code statement,
return CallNextHookEx(hookID, nCode, wParam, ref lParam);
[DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
private static extern IntPtr CallNextHookEx(IntPtr hhk, int nCode,
IntPtr wParam, ref KBDLLHOOKSTRUCT lParam);
This cause to carshed my application. And Can U explain to overcome this issue.

Attach an unmanaged debugger and look for the error. Your structs that you pass to the unmanaged function is probably incorrect/too small/misaligned etc. I cant help you on that.

Use the DOM exposed by the control. You will have to lookup where you need to change that yourself. It is beyond the scope of C#. Try the web forum.

You can. The fact that you do not know how, does not make this impossible.

Hi,
you can get and set the WebBrowser.DocumentText property, hence modify the page any way you like.
you probably will be interested in the Navigating, Navigated and DocumentCompleted events.

Hi,
My application can now check for all the installed windows service on the local machine.
How can I do this for other machines on the network?
For example, from my machine where the application starts, I would also like to check for the windows service names on OTHER machines.
Please note that I do know how to loop through the names of the windows services but not sure how to connect to other machines to do this.
Thanks

The System.ServiceProcess.ServiceController.GetServices function is overloaded. Pass the computer name as one of the arguments
|
|
|
|
|
|
add reference : System.ServiceProcess
then call :
ServiceController[] sc = ServiceController.GetServices("MACHINE2");
