Okay, I know I'm missing something blissfully obvious, but that is my lot in life.

Code:

ib = new IndexBuffer(typeof(short), (WIDTH - 1) * (HEIGHT - 1) * 6, device, Usage.WriteOnly, Pool.Default);
indices = new short[(WIDTH - 1) * (HEIGHT - 1) * 6];
for (int x = 0; x < WIDTH - 1; x++)
    {
        for (int y = 0; y < HEIGHT - 1; y++)
        {
            indices[(x + y * (WIDTH - 1)) * 6] = (short)((x + 1) + (y + 1) * WIDTH);
            indices[(x + y * (WIDTH - 1)) * 6 + 1] = (short)((x + 1) + y * WIDTH);
            indices[(x + y * (WIDTH - 1)) * 6 + 2] = (short)(x + y * WIDTH);
            indices[(x + y * (WIDTH - 1)) * 6 + 3] = (short)((x + 1) + (y + 1) * WIDTH);
            indices[(x + y * (WIDTH - 1)) * 6 + 4] = (short)(x + y * WIDTH);
            indices[(x + y * (WIDTH - 1)) * 6 + 5] = (short)(x + (y + 1) * WIDTH);
        }
   }

What is(are) the best class(es) to store pieces of xml for latter creation of XmlDataDocument out of them?

You know how you usually make Xml Schema-defined types into C# classes? Well, I want each one of those to be able to output its own piece of XML. This way I can build the class hierarchy corresponding to the schema hierarchy, and one line of code would output the complete xml of some specific schema type, or the whole XML page.

For example:

class Phone
{
public string id;
public string phone;

public Phone()
{}

public INSERT_SOME_CLASS_HERE getXml()
{
INSERT_SOME_CLASS_HERE myObject = new INSERT_SOME_CLASS_HERE();

// Building xml elements

return myObject;
}

}

Any example what class should I use? Manipulate with XmlElement? XmlNode? Or should I just use XmlDataDocuments, and keep merge them together somehow?

Thanks.

Say, I have two classes:

Buyer
Seller

Say, I also have a class

User

which can be either Buyer or Seller, or both, or anonymous. In fact, I want User to represent the current session, and have the following member variables:
(i wrote self-explanatory members' names)

User.the_page_Im_on_right_now

User.the_page_I_wanned_to_visit_but_got_redirected_to_login

User.class_seller_or_null_if_im_not_seller

User.class_buyer_or_null_if_im_not_buyer

As you see, the User class only makes sense to keep during a session. How can I connect this kind of class with a session, so that the object of the User class gets created when a user goes to the website, it disappears when user leaves; and it stays available as the user goes from page to page?

Maybe there are built in functions for this whole thing, and I'm inventing a wheel?

(I'm using ASP.NET 2.0 with C#)

Is it possible to make such a method that you can use like a static or like a non-static method?

class Class
{
public static void method()
{
// ...
}
}

and then use it as follows:

Class instance = new Class();
instance.method();

and also be able to use it like this:

Class.method();

Probably simple question, but too awkward for a search engine.

I am writing a simple c# app in Visual C# 2005 Express to connect to a java webservice. I am basing my code off of an Visual Basic 2003 app that someone else wrote that doesn't do all that I want. My problem is I keep getting the following error messages when I try to use the service.

A first chance exception of type 'System.Net.WebException' occurred in System.Web.Services.dll
The request failed with HTTP status 404: Not Found.


public bool Work(string request, string response, string environment)
{
StreamReader fileStream = new StreamReader(request);
string content = fileStream.ReadToEnd();
VitalWS.WebServiceFacadeService webService = new VitalWS.WebServiceFacadeService();
string cmdLine;
if (environment != "veasm" || environment != "veasm2")
{
cmdLine = "https://" + environment + ".mreports.com/ws/services/webServiceFacade";
}
else
{
cmdLine = "http://" + environment + ".mreports.com/ws/services/webServiceFacade";
}
webService.Url = cmdLine;
X509Certificate privateKeyCertificate = null;
X509CertificateStore store = new
X509CertificateStore(X509CertificateStore.StoreProvider.System,
X509CertificateStore.StoreLocation.CurrentUser,"My");
bool open = store.OpenRead();
foreach (X509Certificate certificate in store.Certificates)
{
if (certificate.Subject.IndexOf("wamueast") > 1)
{
privateKeyCertificate = certificate;
}
}
if (store != null)
{
store.Close();
}
Console.WriteLine("Certificate CN:" + privateKeyCertificate.Subject);
webService.RequestSoapContext.Path.MustUnderstand = false;
X509SecurityToken digitalSignatureSecurityToken = new X509SecurityToken(privateKeyCertificate);
webService.RequestSoapContext.Security.Tokens.Add(digitalSignatureSecurityToken);
Signature digitalSignature = new Signature(digitalSignatureSecurityToken);
digitalSignature.SignatureOptions = SignatureOptions.IncludeNone;
digitalSignature.SignatureOptions = SignatureOptions.IncludeSoapBody;
webService.RequestSoapContext.Security.Elements.Add(digitalSignature);
string webResponse = null;
bool result = false;
try
{
webResponse = webService.executeService(content);
return result;
}
catch (System.Net.WebException we)
{
Console.WriteLine(we.Message);
return result;
}
}

Can anyone offer a suggestion why this does not seem to work? I know that the url for the webservice is correct because I can use the buggy VB.Net app to get a response.

Thanks

In Visual Studio.NET Pro, my solution has two projects -- one WebSite project, and one SQL Server project. I want to move the two projects into different physical directories on my HDD, and preserve the same solution. When I do that, the Solution complains that it can't find the projects (duh). If I try to "Add Existing Items", then I am able to add the SQL Server project, but Website project does not have a file like ".csproj", therefore adding them again after moving them doesn't seem to work. Could someone suggest how can I move the projects into different folder while preserving my solution?

(This annoying stuff has to be done, because AnkhSVN does not work unless projects are in the solution directory, grrr).

Follow-up: I moved the projects, and edited the addresses in the .sln file. Now AnkhSVN is able to export the SQL Server project to the Subversion repository, but it still refuses to export the WebSite project, complaining that it is not under the solution root directory. I've already put it in the same folder as the sln file, it still complains. Do you know why?

I recently got to see a demo of the next version of ADO.Net by Shyam Pather introducing some pretty drastic changes from the current version. They are maintaining backwards compatibility, however they are adding a lot of new features which I think will alter the way data-access with .Net is done in pretty significant ways. There's a fairly well integrated support for more of an ORM approach using a tweaked SQL dialect, for example. Also, there's upcoming support for LINQ...

Shyam does a better job of introducing it...check it out here: http://blogs.msdn.com/dataaccess/archive/2006/06/22/642260.aspx

Could anyone please help me with .NET performance counters? I am trying to read the % Processor Time of all of the currently running processes on the system. Here is my code. Assume that thisInstances is a string array containing elements, each of which is one process running on the system (I checked this myself using the debugger):

					foreach (string thisInstance in thisInstances)
					{
						thisPerfCounter = new PerformanceCounter();
						thisPerfCounter.CategoryName = "Process";
						thisPerfCounter.CounterName = "% Processor Time";
						thisPerfCounter.InstanceName = thisInstance;
						thisPerfCounter.NextValue();

							System.Windows.Forms.MessageBox.Show(thisInstance + ": " + thisPerfCounter.NextValue().ToString());
						thisPerfCounter.Dispose();
						thisPerfCounter = null;
						thisProcess = null;
					}

I may have a few development projects to undertake in the next while which I will be using to build up my work experience to acquire a programming job in the future. By education, I'm primarily a C++ programmer. But in this day and age, I find that a lot of the jobs at my level (entry-level) are looking for everything but C++.

My question is whether or not C# has enough of a following to make it a good language to gain experience in, (as in, are there a reasonable number of jobs out there for entry level C# programmers), or if I should be turning my focuses elsewhere?

The applications I'd be writing as part of my job will involve standard business practices (scheduling, POS, etc).

Any insight people can offer is much appreciated :)

I'm self-learning C# and last night I felt that I had learned enough to try and make a very simple IRC connection client. And so far it seems to be working fairly well except for the minor fact that you can't really see any of the incoming data. I know this because I've yet to program a way to get it. Why? Because I'm not entirely sure how I should continually get all of the incoming data. This is where I could really use some help. I'd also like some comments or advice on the code itself. It's split up into two files, the Program class which is just the main method, and the IRC class which handles all of the IRC information and commands.

Can anyone recommend a reasonably decent free (preferably open source) reporting package (think crystal reports) that I can use with C#?

My google-fu doesn't seem to be getting me anywhere with this.

Failing that, can anyone recommend some other reporting software that is reasonably priced? I am using an Express Edition of Visual Studio, and unless I'm missing something, it doesn't include Crystal Reports.

Hi guys,

I create stored procedures in the following way:

[SqlProcedure]
public static void addrow(string blah1, string blah2)
{
// the code
}

and this works fine.

However, now I'm trying to pass an ArrayList instead of a string.

[SqlProcedure]
public static void addrow(ArrayList blah1, ArrayList blah2)
{
// the code
}

and when I deploy the server project, visual studio yells at me saying that it doesn't know such thing as an ArrayList.

But the following line is present:

using System.Collections;

Still it doesn't work.

Is there no way to pass an ArrayList into a managed stored procedure?

I was wondering if PerformanceCounter classes in .NET (specifically those monitoring processor time) would return samples based upon a possible max value of 100, or a possible max value of (100 * number of logical processors)? On a multithreaded Pentium IV I am seeing Idle values of 193 - 198, which I assume is simply the total of the Idle processes on logical processor 0 and logical processor 1.

Is there a better way to get the true average Idle process time than to simply divide this sample by the number of logical processors in the system? Is there a performance counter that will give me a normalized figure on a set scale (e.g. 0-1, 0-100, etc.) per process?

Thanks for any information.

Hi all. I'm at it again and this time I'm trying to use the ArrayList class that's found within the System.Collections namespace. However, I don't seem to HAVE this namespace. I've added System, and I've tried to manually add System.Collections into the references but I don't see it. So I type it in manually, and try to do an ArrayList but it says "The type or namespace 'ArrayList' could not be found (are you missing a using directive or an assembly reference?)" and I'm at a loss of how to fix this.

I'm using version 2.0.50727 of the .NET Framework, which if I'm not mistaken is the newer version (at least Microsoft's Update doesn't show any newer versions). I'm using Visual C# 2005, as well.

Anyone have any ideas on how to fix this? I really need this ArrayList to finish this project.

Hello, long time lurker, first time poster here. :)

I'm currently working with your typical sandbox Northwind Database and C# .NET. I have set up a Datagrid class to spit out the contents of a certain table in the database (Employees). However, one of the fields in the database, "Photo", currently takes a Binary representation of an image.

My goal is to take the binary and convert it into a relevant image for display on a website, all in a Datagrid control.

Would anybody know of a way to go about doing this, or at least point me in the right direction?

Thanks!

Visual C# 2003, with latest .NET 1.1 SDK patch.

I've created a simple test app containing a list box and a button.  When the button is clicked on, it adds three items to the listBox and refreshes.  I can see the refresh, but no text is viewable.  Yes, the text is black on white.  I've highlighted an entry to show that the text just isn't showing up.

Anyone have any idea?  I've tried with and without the Refresh() - which should be called automatically by EndUpdate() anyways.

private void button1_Click(object sender, System.EventArgs e)
{
listBox1.Items.Clear();

listBox1.BeginUpdate();
listBox1.Items.Add("test1");
listBox1.Items.Add("test2");
listBox1.Items.Add("test3");
listBox1.EndUpdate();
listBox1.Refresh();
}

I recently got a Cingular 2125 that has WM 5 Smartphone Edition on it. I want to learn how to do some programming for it. Thing is though there's alot of literature online about SP 2003 programming, but not alot on WM 5. I did do some reading on SP 2003, but is all that basically useless given the new WM5? Or are the programming styles similar, akin more to .Net 1.0 - 1.1 vs 1.1 - 2.0?

Basically can I take 2003 knowledge and apply it to developing programs for WM5? Or are the two of them completely separate beasts? Thanks.

If I have ArrayList G and its object is also ArrayList H, how can I get the information stored in the ArrayList H? A year ago I was doing the following:


IEnumerator enumerator = G.GetEnumerator();
enumerator.MoveNext();
string h=enumerator.Current.ToString();


now this operation gives me the following g="System.Collections.ArrayList", which is a type of object Н but not its content.

How can I get the content? I've searched the MSDN but they do not consider ArrayList as an object of another ArrayList.
