Remember that those XML files must be in the same directory as the assemblies you're referencing. This is how VS.NET and other IDEs (or some tools out there) find the necessary documentation. So, if you move your assemblies out of the target output directories, make sure you take the XML documentation files with them.

That would be nice, wouldn't it? 
Actually what happens is that the XML comments that you wrote get compiled into an entirely separate XML file in your bin directory with the same name as your assembly. Then VS.NET uses that information at design time to populate the help cache. If you move the assembly, you also need to move the XML file with it.
Hope that helps.

I wonder..
Would it be possible to add the documentation.xml-file to your project? This would only work when and if the Xml-file is generated before the assembly is compiled.

Hello,
I'm trying to decide what is the best way to store my application's location, size, state and also a bunch of other options such as font, color, recently viewed files, etc.
Should I store the information in the registry or in some type of a file? Do people still use .ini files for saving settings anymore? In an older version of my application, I stored the information in a .ini file, but I'm not sure if that is the best way to do it.
Thanks in advance,
Blake

If maintaning xcopy deployment is a factor you should avoid the registry. Otherwise storing it in an ini or other type of file is probably your best solution.

Hi there!
Recently I encountered a surprising effect of the C# language. I wrote the following lines:
public class A
{
public string name;
}
public class X
{
public static void Main()
{
A a1 = new A();
A a2 = new A();
A a;
A _a;
a = a1;
_a = a;
_a.name = "TTT";
//ok, variable "a1" is modified
a = a2; //change the reference target to instance "a2"
_a.name = "SSS";
//?!?, still variable "a1" is modified, although
//the reference is pointing to variable "a2" !!!
_a = a;
_a.name = "SSS";
//ok, now variable "a2" is modified
}
Om, what's happening here? It should be possible to create references to a reference in C#? Is there any optimization action done in the background, that translates a "ref to ref" to a "ref", what would explain the ignoring of the changed ref variable?
Greetings,
Matej

A Reference is just a fancy word for a pointer. Consider...
A a1 = new A();
A a2 = a1;
A a3 = a2;
So everything is pointing to the same instance of the class A
Now...
a2 = new A();
What do you think happens? ...
a1 still points to the first instance
a2 now points to the second instance
a3 still points to the first instance
Why? Because a3 was never told to point to anything else. When a3 was created it was told to point to the first instance, not to a2 - In other words it was told to point to whatever a2 was currently pointing to. a2 is still at liberty to point to something else in the future.
Does this help clear things up?

Yes, thank you!
I was assuming something like this. So this means there is no way to let a reference point to a reference instead to the instanced object itself in C#, like it was possible in C++?
This would be a great thing e.g. for a list (ArrayList, etc.). If the listelements would point to a reference variable not to an instance I would just have to change that ref variable in order to change all list elements with that target at one time!
But it seems, that if I want to do so, I will have to change the instantiated object itself, won't I?

Why does VS.NET 2003 delete everything from the debug directory, when building a solution? I can't run my application, because when I build it, app.exe.config is removed from the debug directory.
Please HELP
|
|

|

This is the behavior of practically any build system - it removes the old stuff. VS.NET does have an undocumented (at least, from what I've read) feature where any file named app.config in your project gets renamed appropriately and moved to your target output directory. You could either add this file to your project and make sure the settings are correct in that, or have a backup app.exe.config file in your target output directories that you can copy to the appropriate name after building.

If you have a "myapp.exe.config" file in your output folder (e.g. "Debug"), VS.NET tries to replace it with one within your project directory, if it doesn't find it, it deletes it. You can avoid this by making it read-only.
But the better solution is:
-Add an "app.config" (exactly this name) to your VS.NET project. Use it as your configuration file.
- Now everytime you change this file and build your project, it gets copied as "myapp.exe.config" into the output folder.

I want a control that is based off the Panel control, I would like to be able to drag and drop items on this the same way that i can for the Panel on the toolbox. when i create this custom control it's design view is that of a control that you can not drag and drop things on it.
how can i get my custom panel control to act and feel like the base Panel that comes out of the box?
thanks

What do you mean, ...based off the Panel control...? Do you mean you extended it? This should work if you did because the designer usually uses the designers from classes up the class chain. Hmm. If nothing else, use ildasm.exe to find out the what Type the DesignerAttribute of the Panel class uses, and use that same attribute (specifying the same Type, which is probably a string representation, but if not it will use the typeof statement) to attribute your class.
You could also implement your own designer than enables drag and drop - and filter the types of controls that can be added - by reading the docs on the DesignerAttribute and the IDesigner interface, although it's typically easier to start off (i.e., extend) with a root designer class, like the ParentControlDesigner, which has support for controls that contain nested controls (like you want).

Hello,
I have a C# application I want to speed up.
Does anybody know a tool to monitor it and tell me in which part of the process it spends its time ?
Thanks

This is propably a question from which everyone should know the answer, but I want to ask it anyway. 
If I have an enum, like this:
[Flags]
public enum ThisIsAnEnum
{
None,
FirstFlag,
SecondFlag,
ThirdFlag,
FourthFlag
}
How do I test whether a specific value is used?
Is this the proper way?
ThisIsAnEnum enumValue = ThisIsAnEnum.SecondFlag | ThisIsAnEnum.FourthFlag;
if (enumValue & ThisIsAnEnum.SecondFlag != 0)
{
}
Or is there some method like Flags.Match(), but for a bitfield value?
And why do I have to add the values of the enum to it's members? Like this:
[Flags]
public enum ThisIsAnEnum
{
None = 0,
FirstFlag = 1,
SecondFlag = 2,
ThirdFlag = 4,
FourthFlag = 8
}
If I don't, their values will be 0, 1, 2, 3, 4, 5, 6..., and not 0, 1, 2, 4, 8, 16... .
Thanks in advance,

Close:
ThisIsAnEnum enumValue = ThisIsAnEnum.SecondFlag | ThisIsAnEnum.FourthFlag;
if ((enumValue & ThisIsAnEnum.SecondFlag) != 0)
{
}Putting the bitwise & statement in its own pair of parens is necessary due to operator precedence.

[Flags] is merely an attribute that's put on enums - it doesn't change the compiler behavior. We don't automatically switch to powers of two because people often want to define combinations of flags, and what was going on would be much less clear if that was the case. Ditto for looking at the numeric values someplace and having to translate back to the identifiers.
|
|
|
|
|
Okay, but what use is the Flagsattribute then? If I'm not mistaken, I can add enum values together using |, even when I didn't set the Flagsattribute.
|
|
|
|
|
[Flags] isn't really a compiler thing. It's used by object browsers to tell people what kind of enumeration it is, and Enum.ToString() bases its behavior on whether [Flags] is present.

i have written the code to transfer image file through sockets. Below is the code for client. It just runs and exit nothing happens. Can anybody help?
In this code first i get the file size then the actual file through bytes.
using System;
using System.Net.Sockets;
using System.IO;
using System.Threading;
namespace ImageClient
{
///
/// Summary description for Class1.
///
class Class1
{
bool flag = true;
Socket clientSocket;
AsyncCallback pnfCallback = null;
int fileSize;
byte[] buffer = new byte[1024];
///
/// The main entry point for the application.
///
[STAThread]
static void Main(string[] args)
{
Class1 c = new Class1();
c.clientSocket = new Socket(AddressFamily.InterNetwork,SocketType.Stream,ProtocolType.Tcp);
System.Net.IPEndPoint ipend = new System.Net.IPEndPoint(System.Net.IPAddress.Parse(args[0]),8221);
c.clientSocket.Connect(ipend);
c.WaitForData();
}
public void WaitForData()
{
if(pnfCallback == null)
{
pnfCallback = new AsyncCallback(onDataReceived);
}
IAsyncResult result = clientSocket.BeginReceive(buffer,0,buffer.Length,SocketFlags.None,pnfCallback,null);
}
public void onDataReceived(IAsyncResult result)
{
if(flag)
{
int count = clientSocket.EndReceive(result);
char[] chars = new char[count];
System.Text.Encoding.Default.GetDecoder().GetChars(buffer,0,count,chars,0);
fileSize = int.Parse(new string(chars));
Console.WriteLine("Got the buffer " + fileSize);
Console.ReadLine();
flag=false;
buffer = null;
buffer = new byte[fileSize];
WaitForData();
}
else
{
clientSocket.EndReceive(result);
FileStream fs = new FileStream("c:/def.gif",FileMode.Create);
fs.Write(buffer,0,buffer.Length);
fs.Flush();
fs.Close();
WaitForData();
}
}
}
}

Well, You are using an Asyncronous callback which means that the function will return immediately without waiting for the data to be received. Once the data is received the your callback method (onDataReceived)will be invoked. However, because your application has exited before the data is received the callback method will never be invoked and so no data will received either.
