I don't know if this is even possible, but I am looking for a way to programmatically tell whether a tablet is connected to the network wirelessly or is it connected to the network using a network cable plugged in. All the ways I've found just say whether it's connected or not and doesn't tell how it is connected.
Thanks for any help

System.Net.NetworkInformation.NetworkInterfaceType contains that info. Look in the System.Net.NetworkInformation namespace on how to access that information.

Thanks, that's exactly what I was looking for.

I have created an 'grid' of text boxes 17 (rows) by 20 (columns) within a groupbox.
This is like using a conrtol array in VB6.
I gave each a unique name e.g. txtboxR08C12 (row 8 column 12)
Just prior to adding the control to the group box I added an EventHandler to the textbox.
How can I identify in the EventHandler exactly which of the textboxes (preferably by name). So that I can amend the background colour and the contents to reflect a count (determined elsewhere in my code and stored in an array)

spd69,
The standard event param syntax is:
Event(object sender, EventArgs e);
Sender is the object which has raised the event, so in your case, it would be the textbox.

Gareth.

dim x as textbox = ctype(sender,textbox)
if x.name = "txtboxR08C12" ....
(I think my vb syntax is correct)

Thanks for your answer
I mentioned vb6 as that is where I know control arrays from. But I was looking for a c# method.
Thank you for your time

TextBox tb = sender as Textbox;
if (tb.Name == ...
|
|

Sorry, I amswer questions in several forums. The same logic applies, cast sender to the right type and you can get the name.

<br />
TextBox box = sender as TextBox;<br />
box will then become the textbox that has fired the event, and you can handle it accordingly.

thanks this worked a treat.
Sorry about the delay other matters took up my time until now (2:13am - lol)

Hiya guys!
I'm new to this forum, and new to C#, and have hit upon a snag in a project i'm working on.
I am trying to load an existing webpage into .net, and populate the fields on this page.
So far, I have created a new web form, and I can grab data from the DOM.
I have found the fieldnames that I want to populate, but I have no idea how to populate them!
It looks like the webpage is read only, as I cannot set any properties.
Can someone please point me in the right direction?
Sorry if its a simple question, but I have only started learning c# this week.
Thanks in advance!

You can get quick response, if you will post into the right forum.
Like your question is related asp.net, so it should be post into the Asp.Net section not C#.

Hi Guys
I want to write a piece of code to automate a network printer installation on a vista client. I didn't found samples on the web with any possible solutions. I tried to use WMI but at this I have no solution for my problem
Every time when I run this code I habe an "Generic failure" when execute the printerObject.Put(options); method.
So I hope anyone of you can help me to find a reason to this issue.
Thanks in advanced.
Dany
Code:
public bool AddPrinter(string printerName, string printerDriver, string portName, bool sharedPrinter)
{
bool result = false;
try
{
//init Win32_Printer class
ManagementClass printerClass = InitClass("Win32_Printer");
SelectQuery selectQuery = new SelectQuery();
IPHostEntry iphe = Dns.Resolve(printerName);
string priterport = 9100.ToString() ;
//create new Win32_Printer object
ManagementObject printerObject = printerClass.CreateInstance();
//AddPrinterPort(portName, iphe.AddressList.GetValue(0).ToString(), priterport);
AddPrinterPort(portName, printerName, priterport);
if (portName == null || portName.Length == 0)
printerObject["PortName"] = "LPT1:";
else
{
//if (portName[portName.Length - 1] != ':')
// printerObject["PortName"] = (portName + ":");
//else
printerObject["PortName"] = portName;
}
//set driver and device names
printerObject["DriverName"] = printerDriver;
printerObject["DeviceID"] = printerName;
//set sharing
if (sharedPrinter)
{
printerObject["Shared"] = sharedPrinter;
printerObject["ShareName"] = printerName;
}
printerObject["comment"] = "Zeljko Philipp";
// specify put options: update or create
PutOptions options = new PutOptions();
options.Type = PutType.UpdateOrCreate;
//put a newly created object to WMI objects set
printerObject.Put(options);
result = true;
}
catch (Exception ex)
{
System.Windows.Forms.MessageBox.Show("WMI exception: {0}", ex.Message);
throw new Exception(String.Format("WMI exception: {0}", ex.Message));
}
return result;
}

I can't seem to find anything to help my desktop application load a website and pass through the current logged in user.
I know I can get the current logged in user by
string NTUsername = System.Security.Principal.WindowsIdentity.GetCurrent().Name.ToString();
and I have seen posts where you can specify the Username in the URL but neither are working
url = "http://username:" + NTUsername + "@subdomain.domain.com/default.aspx";
I have even tried to hard code in my username/domain. Can someone help give me some insight on how to pass the current logged in user to the web browser control?

Well the site has to support that yes? Does it? You have to do whatever the site requires.

I call the below code from the MouseClick event of a control. However, it doesnt seem a good idea to be constantly creating gfx objects every time the user clicks the mouse.
private void ClickedEdge(Point mousePoint)
{
_selectedEdge = null;
Graphics gfx = this.CreateGraphics();
Rectangle clickedRect = new Rectangle(mousePoint, new Size(1, 1));
foreach (EdgeObj edge in _edgeItems)
{
Rectangle edgeRect = Rectangle.Round(edge.Region.GetBounds(gfx));
if (clickedRect.IntersectsWith(edgeRect))
{
_selectedEdge = edge;
break;
}
}
}
So, does anyone know of a better way to find out if the mouse has clicked on a line which has been drawn onto the control?
Regards,
Gareth.

Save the extents of all the primitives drawn (lines, rects, polygons) in a List, for example
List<Primitive> primitivesDrawn = new List<Primitive>();
with Primitive being an abstract class like this (just an example, can be done different):
public abstract class Primitive
{
public IEnumerable<Point> Points { get; set; }
public abstract bool Intersects(Point pt);
public abstract bool Intersects(Rect pt);
}
and some primitives like:
public class Line : Primitive;
public class Triangle : Primitive;
public class Rectangle : Primitive;
This data structure can be used for both drawing it to the control as well as doing intersection testing and much more.

This could be so much more simple. The equation of a line: Y = mX + C X and Y are abvious m is the gradient and C is an offset.
So, if you can get the equation of your lines then you could use something like this:
void ClickedEdge(Point mousePoint)
{
if(mousePoint.Y == ( lineM*mousePoint.X +lineC))
}
Although you might want to check that mousePoint.Y is +/- 1 from the calculated Y position because its gonna be almost imposible to click the line exactly (since you can't click between pixels)
float Y = lineM*mousePoint.X +lineC;
Y = Y - mousePoint.Y;
Y *= Y;
if(Y <= 1)
To get the equation for your line:
m = (endY - startY)/(endX - startX);<br />
c = m*startX - startY;

SK Genius,
What is lineX? Below is what i have done from your suggestion.
int lineM = (edge.EndPoint.Y - edge.StartPoint.Y) / (edge.EndPoint.X - edge.StartPoint.Y);
int lineC = lineM * edge.StartPoint.X - edge.StartPoint.Y;
int lineX = 0;
if (mousePoint.Y == (lineM * lineX + lineC))
Trace.WriteLine("hit");
Regards,
Gareth.

Oops, not sure what i was thinking, that should just be mousePoint.X

SK Genius,
It doesn't seem to be working. The cal of lineM * mousePoint.X + lineC is just giving me tons of numbers that dont even come close to mousePoint.Y.

Gareth.
