string str;<br />
byte [] charStr = new byte[] {(byte)'T', (byte)'e', (byte)'s', (byte)'t', 0, 0, 0, 0, 0, 0};<br />
str = Encoding.ASCII.GetString(charStr);<br />
<br />
str = str.TrimEnd(new char[]{'\0'});<br />
This code works. Make sure you are assigning the return value of TrimEnd method to your string. It does not actually trim the contents of string object but rather generates a new trimmed string.

After looking at docs, this is even better:
<br />
str = str.TrimEnd('\0');<br />
Also, if you are reading a null terminated string, there is a chance you have garbage characters after the terminating null. This will prevent Trim methods from working. So, your best approach would be:
<br />
int Index = str.IndexOf('\0');<br />
if (Index >= 0)<br />
str = str.Substring(0, Index);<br />

I wrote a windows application using threads. There is some images is in my main form. Form was working well. Then i added a delegate to add controls to main form from another thread. Like this:
using System.Xml;
using System.Threading;
delegate void AddTabPage( string strUniqueID );
namespace ggg
But now, i get a runtime error like this:
An unhandled exception of type 'System.Resources.MissingManifestResourceException' occurred in mscorlib.dll
Additional information: Could not find any resources appropriate for the specified culture (or the neutral culture) in the given assembly. Make sure "Form_OperatorMain.resources" was correctly embedded or linked into assembly "SupportAliveOperator".
baseName: Form_OperatorMain locationInfo: SupportAliveOperator.Form_OperatorMain resource file name: Form_OperatorMain.resources assembly: SupportAliveOperator, Version=1.0.1238.30259, Culture=neutral, PublicKeyToken=null
can anyone help me?
thanks..

how can i put an icon in a menu item
thanks

You can't do it using standart .Net menu, but you can use this cool library[^].
(Menus with icons, floating dockable panels etc..)
i'm only pointer to myself

|
|

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
