I think it's been explained pretty well already, but just in case...
static methods are available without an instance of the class. Non static methods are only available through an instance of the class.
This gives you two options in your case. Either
1. Make the Test method static
public static Double Test(Double Val1, Double Val2, Double Val3)
or
2. Create a new instance of the class that holds the method (Program in this case).
Double Result = new Program().Test(A,B,C);
alternative
Program program = new Program();
Double Result = program.Test(A,B,C);

What is the C# equivalent to the following VB.NET code?
Delegate Sub SetStatus(ByVal Text As String)
Private Sub SetStatusStrip(ByVal Text As String)
Dim d As New SetStatus(Sub()
End Sub)
Me.Invoke(d, New Object() {Text})
End Sub
|

This seems homeworky but since you could just whip it through an autotranslater anyway, here you go:
delegate void SetStatus(string text);
private void SetStatusStrip(string text){
Invoke(text => {
}, new object[] { text } );
}
I think that's right. Invoke is a bit sniffy sometimes, you might need to cast the lambda, but I don't think so. Although it seems like the VB method you're generating for the delegate doesn't actually use a parameter so there's no reason you need to use that delegate for the inner method.

Doesn't sound like homework to me; I don't know any schools that mix VB/C#, but I do know that managers "insist" on keeping their codebase in a single language

I assure you it's not homework. I've been programming (promoted from drafting) for about three years. I started in VB.Net and am now trying to convert to C#. That doesn't seem to work. How can I cast a lambda expression? Thanks for the auto translate idea. I ran the code through a couple and none seem to work. Thanks for your help.

Thank you sir. The following is what I ended up using and it works great.
SetStatus d = new SetStatus( (string myText) =>
{
});
this.Invoke(d, new object[] { _text });

How can I save an Excel file which will prompt user to select where to save? What save mode should I use?
|
|
|
|

More detail is needed.
Is this a web app? WinForms? Excel VBA code? What?
How are you generating the workbook to "save"??
There's no such thing as a "save model". Your use of the term could mean anything.

Prompting the user for a save-location is done using the standard SaveFileDialog. It doesn't matter what type of file you want to save, the dialog is always the same.
Check out the documentation[^].

Ladies And Gentlemen:
Here I use a SerialPort to send and receive message(of Bytes).
But it cannot really work.
MCU can send a string to PC, and PC can send a string to MCU too.
The problem is , when PC sent a string first,later when you about to send a string to PC from MCU ,it losts a byte,the first or the second one.
private void serialPort1_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)
{
int temp = serialPort1.ReadByte();
if (IsAddrConfirmed == 0 && NeedAddrConfirm == 1)
{
IsAddr = confirmAddr((byte)temp);
IsAddrConfirmed = 1;
}
if (!IsAddr && AddrBacked_2 == 1)
{
try
{
textBox3.Text += "temp是：" + temp + "\r\n";
textBox3.Text += "收到字符串：" + (char)temp + serialPort1.ReadLine() + "\r\n";
When dataReceived,temp got a value
Look at the last two or three lines ,is it the point?
Thank you very much,but sorry for my bad English.

You're right, the English is rough, but we'll work through that... The sample code is interesting, but far too little to make an educated guess. The non-English characters are confusing to us, but to a serial port, bytes is bytes - it doesn't care. There's a clue in the fact that the first couple of bytes are being lost, I think. The fact that you get any meaningful data at all indicates that you have the baud rate set correctly, so we can forget that. But the handshaking might be mismatched. The PC port and the MCU port must be set to use the same protocol in order to properly sync the messages. Modern PCs will attempt to auto-negotiate handshaking if the mode is set to 'none', I believe, but MCUs aren't as sophisticated. Confirm that the handshaking protocols are identical.
Another possibility is that you (or the MCU) are expecting to have the PC's undivided attention to the data stream incoming on the serial port. That's not the case with a multi-tasking OS like Windows. You'll want to dedicate a thread to listening on the serial port with a fairly high priority in order to catch the leading bits of a randomly-generated message from the MCU. If you don't, Windows may be off doing something else when the first couple of bytes arrive, and they'll be lost.
Post a bit more of your code so that we can see what you've set up the system to do, and feel free to post the MCU code, as well. It helps to see what both sides of the conversation are expecting from each other. I know that serial communications is old and well established, but it's quirky at best, and the "standard" isn't too well enforced. Every bit of information you can provide will be helpful.

I am trying to scrape a web page. The URL is
http://reports.ieso.ca/public/GenOutputCapability/PUB_GenOutputCapability.xml
If I open the link in a browser window there is information about when the report was created, totals, etc. If I scrape the URL from C# using a WebClient or WebRequest, only the XML file is returned. It appears that much of the information on the page is stored in a dymanically created style sheet on their web site.
Is there a way to use a WebClient or WebRequest to get exactly what I see on the web page?
Thanks,
Mark Jackson

Dunno. Maybe try the WebBrowser control and check its document property.

Some idiot voted you a 1 for a perfectly reasonable answer.

It isn't an html page (if that's what you mean by a web page), it's XML. The XML contains a link to a stylesheet:
="text/xsl"="http://reports.ieso.ca/docrefs/stylesheet/GenOutputCapability_HTML_t1-1.xsl"
This is used by your browser to transform the XML into HTML, which it displays (assuming your browser supports this).
If you are using the WebBrowser (as Piebald Consultant suggests) control, you might need to transform yourself. This article has a basic outline of how: http://ivanov.wordpress.com/2006/11/17/xml-to-html/[^]
Obviously, you'll need to get the transform file first, which means parsing the XML to get its location and downloading it after the XML has been received.

The calculation of the totals is done by the XSD, along with the layout.
You have two options: parse the XML and do the data manipulation that you need yourself (all the primary data is in the XML, i.e. all the information that is displayed can be generated from it), or use a XSD-capable library to turn the XML into HTML and then parse information out of that.
I'd go the first way: read that XML into a DataTable or a List<Generator> (some parsing code will probably be needed though if you set up your objects correctly you should be able to Linq-to-XML-load it), and then do grouping, totalling etc as you require.

I took the easy route which was to create a small forms application that used a WebBrowser object to render the page, then output the text stream from the WebBrowser to an email message. Not elegant but it works.
Thank you for all the replies.

I need to be able to access a number of certificates in a windows service. The code works fine in a console app, but from a service it can't find the certificate.
Is there a special way to install them and open them or both?
Any help would be much appreciated.
Happy programming!!

A service runs before the user logs in, hence it has to run under a different account. It's probably running under the system-account, and that has it's own profile.
Open the services, find yours, ask it's properties, go to the second or third tab, and have it run under the users' profile. That should do the trick
