You don't need a special class or library to do it. It's not "that" hard. I just went through the pain of having to figure it out myself. I posted in two questions and though I didn't get the responses I needed, I was able to peice it together and post the answers.
See these two posts over at CodeGuru.

Ok guys.
Last time james and jonny helped me out. Thanks.
Look at the code outline and tell me how to do it. My main concern is to use a lib that uses pointers as unsafe code. I don't have a clue.. how to go about this... Give some basics about unsafe coding and pointer usage in C#.
This is the error that shows up:
::::The best overloaded method match for 'CsGL.OpenGL.OpenGL.glGenTextures(int, uint*)' has some invalid arguments
The glGenTextures prototype is as follows-
glGenTextures(int,uint*);
Code outline:
.......................................
namespace CORETextureSpace
{
public class CORETexture
{
unsafe public static void CreateTexture(ref uint[] textureArray,string strFileName,int textureID)
{
...............
OpenGL.glGenTextures(1,textureArray);
................
}
}
}
...........................................
namespace GL{
public sealed class myGL5 : Model{
..................
public const uint MAX_TEXTURES = 1;
public static uint[] g_Texture = new uint[MAX_TEXTURES];
....................
public override void Initialize(){
///////////////////////// This line
CORETexture.CreateTexture(ref g_Texture,"bitmap.bmp",0);
}
}
}

Should probably be something like:
fixed(uint* tFirstElm = textureArray)
{
OpenGL.glGenTextures(textureArray.Length, tFirstElm);
}The glGenTextures requires a pointer to a uint which it then treats as an array. So you first have to make sure the array doesn't move (a GC can cause memory to move around) via the fixed keyword. Then you can create the pointer to the first element of the array. That is then passed into glGenTextures.

Hi,
I have two objects, one of type A and one of type B. I want to be able to compare these objects. In my code I want to test for equlity with A.Equals and B.Equals. But I also want to be able to compare A and B type objects with other things. So my code looks like this:
class A
{
override bool Equals(object x)
{
if (x is B)
{
//do something
}
if (x is ...)
{
//do something
}
...
}
}
and the some thing for class B. Is there a better (more elegant) way?
Thanks a lot,
Andrei

Not really, but if it gets more complex, have a look at implementing the IComparer interface. This will allow sorting and other goodies too. Also remember Equals(object) does not make if (a == b) true as well. You will need to override the operator for that, or call a.Equals(b).

According to the MSDN(Windows media service sdk)
My steps:
1.Install the windows media service in msdn.
2.Run the vbs script to register the interop_msxml and windows media service.
3.Use c# to connect remote window media server9.
The code like as following:
// Declare variables.
Type tServerType;
WMSServer RemoteServer;
IWMSPublishingPoints PubPoints;
IWMSPublishingPoint PubPoint;
IWMSBroadcastPublishingPoint BCPubPoint;
//Create playlist
IXMLDOMDocument playlist;
IXMLDOMNode proc_inst, root, node;
IXMLDOMElement element_smil, element_media;
// Retrieve the type information from the Windows
// Media server running on the remote machine.
tServerType = Type.GetTypeFromProgID("WMSServer.Server",
"192.168.108.1");
// Create an instance of the remote server object locally.
RemoteServer = (WMSServer)Activator.CreateInstance(tServerType);
It work smoothly in my local computer to connect the media server.But while I use this programe in other computer in the same LAN,an error message prompt,(Connection Refuse).With this code,there is no api for setting the user id and password,how the media server identify my computer?
How to create the playlist is the other problem,the code liks as following
playlist = (IXMLDOMDocument)RemoteServer.CreatePlaylist();
proc_inst = playlist.createNode(DOMNodeType.NODE_PROCESSING_INSTRUCTION,"wsx","");
playlist.appendChild(proc_inst);
proc_inst.text ="version=1.0";
playlist.save("cti5.wsx");
It compiles well,but it will prompt a warnning message "No enable data source plug-in is available to access the request content.I don't know what's wrong with this?
I will appreciate your help,pls give me a hand.

Hello,
Does anyone got idea how to change the highlight of ListView.
Because its default color is dark-blue.
Actaully, I wanna try to modify the highlight display,
e.g. highlight with only a line frame, not a color filled frame.
I can't find any properties for that..
Anyone who expert on this, could you teach me~ ..
Thank you very much

MS's .NET listview does not support this - it just uses the system highlight color. You might find a listview control here that allows you to do this, or you might want to make your own.

The ListViewEx class in the SharpLibrary allows this and many other customizations. Here is a screenshot: Screenshot

The SharpLibrary looks promising. Great work!
I also liked the icons in your examples. Are they public available?

Does anyone have any clues as to why I would get an "Unhandled Exception of type 'System.Xml.XmlException'" with the following code sniplet? It just says "Additional information: System Error". What is weird is that the error occurs on the red line and does not throw an exception based on my code (It comes from the IDE). Am I missing something blatant here?
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml("XMLTree.xml");
try
{
<font color="red">XmlNodeList xmlnodeList = xmlDoc.SelectNodes("categories");</font>
foreach(XmlNode x in xmlnodeList)
{
MessageBox.Show(x.InnerText);
}
}
catch(System.Xml.XmlException e)
{
MessageBox.Show(e.Message + "\n\n" + e.StackTrace);
}

your mistake is:
xmlDoc.LoadXml("XMLTree.xml");
you want
xmlDoc.Load("XMLTree.xml");
currently your code thinks that "XMLTre.xml" is xml source

My guess: it has nothing to do with the categories XPath you gave.
Your xml document is malformed and the parser gets confused in parsing it.
All I need is a roadmap and then I might be able to find a clue.

i have a quick question about getting sockets to work... im trying to write a simple chat program with a client side program and a server (Async not block sockets). i seem to beable to get the client to connect to the server but i cant get the servers Socket.BeginRecieve method to work correctly it always returns me with a error among the lines of. "The attempted operation is not supported by the object referenced." The code i use for the sockets is as follows.
"Please note that if it is to hard to read here i would be more then happy to send the file. They are both VERY small"
<br />
SentBytes = new Byte[22];<br />
listener = new Socket(AddressFamily.InterNetwork, SocketType.Stream,<br />
ProtocolType.Tcp );<br />
IPAddress hostadd = Dns.Resolve("MyIpIsHere").AddressList[0];<br />
IPEndPoint EPhost = new IPEndPoint(hostadd, 8000);<br />
listener.Bind(EPhost);<br />
listener.Listen(22);<br />
listener.BeginAccept(new AsyncCallback(AcceptCallBack),listener);<br />
listener.BeginReceive(SentBytes,0,15,SocketFlags.MaxIOVectorLength,new AsyncCallback(Reciever),listener);<br />
<br />
private void Reciever(IAsyncResult e)<br />
{<br />
string f = ASCIIEncoding.ASCII.GetString(SentBytes);<br />
MessageBox.Show(f);<br />
listener.EndReceive(e);<br />
}<br />
Any ideas would be great. Thanks Alot

Hello Jesse,
You are trying to call BeginReceive on the wrong socket. The socket you set up with the Listen() and BeginAccept() requests will simply deliver callbacks to you when clients attempt to connect. In your AcceptCallBack function, you must call EndAccept(), which will return to you a new socket connected to that client. You would then call BeginReceive() on that new socket.
Also, in your Receiver() function, you should use this new socket to call EndReceive() on. The return value from this is the number of bytes you actually received (which may be smaller than you requested.) Note also that if something goes wrong with the network connection, the EndReceive() function will throw an exception, you should be prepaired to handle that.
Hope that helps.

Thanks alot burt, I was looking around on the microsoft website and just now figured out the problem. I noticed in vs.nets intelisence that it said it would hand you a new socket but i didnt know what to do with them. thanks alot for clearing that up for me.
I got the program to work (i wouldnt say work good though) now i just need to get it to work 2 way *send / recieve* now. Thanks agian.

p.s :
How is it working for microsoft ? I live about 2 hours from redmond in Wa. Im currently getting my mcsd / bachelors in college right now... hoping to someday work for microsoft.

hi everyone.. im working on a dialog that is very similar to this article written in C++
http://www.codeproject.com/property/saprefs.asp?target=saprefs[^]
i actually have the whole thing working except one small minor glitch that i cant figure out.. i will be posting an article and provide the dialog as freeware, but i need to fix this glitch first..
basicly when you click on the tree on the left i call this function:
private void tvOptionsTree_AfterSelect(object sender, System.Windows.Forms.TreeViewEventArgs e)
{
Form frmSelected = GetSelectedForm();
if (frmSelected == null)
{ MessageBox.Show("An error has occured in the options form which should never occur!\r\ntvOptionsTree_AfterSelect()");
return; }
ShowForm(frmSelected);
}which in turn calls this:
private void ShowForm(Form frmForm)
{
this.SuspendLayout();
if (this.m_frmShownForm != null)
{ this.m_frmShownForm.Enabled = false;
this.m_frmShownForm.Visible = false;
this.RemoveOwnedForm(m_frmShownForm);}
m_frmShownForm = frmForm;
m_frmShownForm.Location = new Point(this.PointToScreen(new Point(0, 0)).X + panel1.Left,
this.PointToScreen(new Point(0, 0)).Y + panel1.Top);
m_frmShownForm.Size = panel1.Size;
m_frmShownForm.FormBorderStyle = FormBorderStyle.None;
m_frmShownForm.ShowInTaskbar = false;
m_frmShownForm.StartPosition = FormStartPosition.Manual;
this.AddOwnedForm(m_frmShownForm);
m_frmShownForm.Enabled = true;
m_frmShownForm.Visible = true;
m_frmShownForm.BringToFront();
m_frmShownForm.Select();
m_frmShownForm.Focus();
m_frmShownForm.Refresh();
}as you can see i put the new form to the front, set it as the focus, enable it, make it visible.. almost everything i can think of.. and it works great.. but..
when the form loads it calls the form load event which in turn calls the tvOptionsTree_AfterSelect function as listed above.. which in turn calls the ShowForm() as listed above.. but i cant click in any of the fields on the dialog on the right hand side which it displayed.. i cant click in a checkbox, i dont get an 'i-beam' when i put the cursor over the textboxes, etc.. as soon as i choose another item in the tree it works.. go back to the starting page and it works.. the whole thing works great after you change the selection on the tree the first time..
ive tried calling tvOptionsTree_AfterSelect multiple times in my form load message handler.. but that doesnt help.. obviously there is something im doing wrong.. the other thing is that when a control in the panel has focus it turns the title bar of the dialog gray, like another dialog has focus.. also my tab order wont go from the main dialog to the subdialog and back and forth.. it cycles through them as seperate dialogs depending on which one has focus.. any suggestions would be much appreciated.. im sure this dialog would help alot of ppl.. i know because the CSAPrefs on CP helped me a bunch in the past..
btw.. i also had to implement moving the subdialog with the options dialog in the options dialog LocationChanged event.. shouldn't it automatically move any child windows when the parent moves? or is it normal to have to override this?
thanks for any and all suggestions!
still a newb.. cut me some slack :P

Hi All,
Does anyone know if .Net 2003's DateTimePicker allows null or blank dates? This problem has forced me to set all dates to '1-1-1900' to simulate a blank date.
Also, did the standard Textbox get the same formatting property as the DataGridTextBox. I find it unreal that this was not in the initial release.
Thanks,
Chris
