Unfortunately, this doesn't help me.
The paper describes how to create a driver package. I already have a ready-to-install driver package and am trying to include it in a setup project.
The setup project doesn't include all files that I told its application to include. What to do about that?
Ciao,

Actually, you'd be repackaging your drivers to put the files in the appropriate locations.

Hi every body
I have Q

And thanks

Please read the "How to get an answer to your question" topic on top.
-> Elaborate on what you're trying to achieve
-> Take time to formulate your question and write full sentences.
-> Indicate what the (isolated) problem is and what you have done to solve the problem yourself.
Example:
If you seek a starting point for information on a project you can always ask the question like - I want to do a project on topic X and have search google/Codeproject/ site whatever on these keyword, but results are insufficient. Could you please point me to some good resources on where to start.
hope this helps in getting the answer you seek.
V.

DataTables (and I think DataViews) can be serialised to XML, which can obviously be sent down a stream. Package your DataRows up in one of them and get the XML serialisation.

You get answers when people are available to give them. You've asked enough questions by now to know that adding comments like this does nothing to increase the urgency with which people reply to you.
As for your question, what have you tried? What technology are you using? WCF? Custom written TCP?

Hello,
Most code used to detect USB relies on a Windows form. The program must register its interest in the USB insertion/removal events by sending its main window handle to RegisterDeviceNotification. What I'm trying to do is make a class library which exposes DeviceIsConnected property without having to use any forms. Any idea if this can be done, and if so how?
Thanks!
Mart

I would use WMI for that task. How To: (Almost) Everything In WMI via C# - Part 3: Hardware[^].
Example:
WqlEventQuery query = new WqlEventQuery(eventName,
new TimeSpan(0, 0, 1),
"TargetInstance isa \"Win32_USBControllerDevice\"");
EventWatcher = new ManagementEventWatcher();
EventWatcher.EventArrived += eventHandler;
EventWatcher.Query = query;

Thanks Kim! I went through the WMI hardware tutorial and was able to run the sample code, but it listed every piece of hardware in the PC except for the one I was interested in, i.e. a USB Input Device under Human Interface Devices. The HID device has this ID: USB\VID_0000&PID_0000&REV_0100. Any idea why I can't communicate with the device using WMI?
Thanks again,
Mart

hello guys.. I want to copy a list which contains key/values. Now I am unable to sort that list, so I thought to copy that list into KeyValuePair() and the sort this. Here is the list
List<Students> list = students.ToList<Students>()
Now I want to copy this into KeyValuePair(). How can I do that? thnx
|
|

|

You can't, per-se, copy a list into a KeyValue pair because you are missing the key part of the KVP. You're going to have to iterate over the list and add it into the KVP one value at a time (using an appropriate element to create the key).
|
|
|
|
|
Students already contains name value pairs like name, degree. I am not able to get the idea how to sort that list which already contains name/values pair.
|
|
|
|
|
So, you have a list of Students (btw, your class should really be called Student as it maps to a single student) and you want to sort on the data, e.g. the student Name. What you could do, using Linq for instance:
var output = students.OrderBy(student => student.Name);
|
|
|
|
|
|
If the only reason you want to put it in a KVP is to sort it, you'd be better off having Students (by the way, it should probably be 'Student' unless that class is itself a wrapper for a group of students) implement IComparable and just calling List.Sort. (Or, if you don't own Students, writing a IComparator<Students>.)

Students already contains name value pairs like name, degree. I am not able to get the idea how to sort that list which already contains name/values pair.
|
|
|
|
|
So do you want to sort the students, or do you want to mix up all the internal name/value pairs of all the students and sort that? Please provide a simple sample (3 students or something) and tell us what your expected output should be.
|

This[^] should give you enough information to sort your list of students in any way you like.

I have a context menu with 11 items on it, and I want to use a single event handler that will catch a click on any one of those menu items. Then I want to know which menu item was clicked and get its text value. I know how to write methods to catch the click event for each menu item individually, but surely I don't have to write a single method for each menu item click, right? This is what I know how to do for a single menu item:
private void menuItem10_Click(object sender, EventArgs e)
{
locationButton.Text = menuItem10.Text;
locationButton.BackColor = System.Drawing.Color.Blue;
}
This is what I'd like to do, but I don't know how to have a single event handler with each menu item registered to it. In other words, can I have a single event handler (we'll call it 'MenuClick') that listens for a click on any one of the menu items in the context menu? Do I have to register each one line by line or can I use a loop?
private void MenuClick(object sender, EventArgs e)
{
System.Windows.Forms.MenuItem clickedMenuItem = sender as System.Windows.Forms.MenuItem;
if (clickedMenuItem != null)
{
locationButton.Text = clickedMenuItem.Text;
locationButton.BackColor = System.Drawing.Color.Blue;
}
}
To register each one, it's like this:
this.menuItem10.Click += new System.EventHandler(this.menuItem10_Click);
To register each one individually seems a bit overkill and I'm looking for a loop instead. But I don't see how you can dynamically name and register a menuItem object using a variable. In other words, I don't see this as being valid:
for (i = 0; i < 12; i++)
{
this.menuItemi.Click += new System.EventHandler(this.menuItemi_Click);
}

That's a bad idea.
namelkcip wrote: .menuItemi_Click
You can do that if you make an array of items.
namelkcip wrote: new System.EventHandler
We haven't had to do that in many years.

if you want each MenuItem of some Menu to have the same click handler, use a simple loop like this:
foreach(MenuItem mi in myMenu.MenuItems) mi.Click+=menuItem_Click;
BTW: mi.Click+=menuItem_Click; is shorthand notation for mi.Click += new System.EventHandler(this.menuItem_Click);
Relying on the MenuItem's text isn't in accordance with defensive programming rules, as you might later on change the item's text (e.g. by introducing Internationalization) and break your code. A better way might be to attach some information (the reference to some object typically) to each of the MenuItems' Tag property, which is available for exactly such purposes.

Is it possible to do this?
Here is my test function which does work locally. How can I get these values remotely, I haven't been able to find much on the net?
Thanks for reading.
NetworkInterface[] adapters = NetworkInterface.GetAllNetworkInterfaces();
foreach (NetworkInterface adapter in adapters)
{
MessageBox.Show(adapter.Name);
MessageBox.Show(adapter.OperationalStatus.ToString());
MessageBox.Show(adapter.Description);
MessageBox.Show(adapter.NetworkInterfaceType.ToString());
MessageBox.Show(adapter.Speed.ToString());
MessageBox.Show(adapter.GetIPProperties().UnicastAddresses[0].Address.ToString());
}

GetAllNetworkInterfaces() is specifically for the local computer, so unless you run it on the remote computer and relay the information back some way, then you can't use it.
You may be able to use WMI if it provides the information you need and the network security configuration allows it. See the WMI "Win32_NetworkAdapter" class...
