Wow - that's exactly what I was looking for to begin with, right down to the property name I was expecting for it - only when I didn't find it did I eventually find the GetCustomAttribute method that didn't work for this. How the heck did I miss that?!?!?!? 
Thanks for pointing out my blindness, I think I'll go get my eyes checked now!

 You need to find all the serializable types within an assembly.
Solution
Instead of testing the implemented interfaces and attributes on every type, you can query the Type.IsSerialized property to determine whether it is marked as serializable, as the following method does:
public static Type[] GetSerializableTypes(Assembly asm)
{
List<Type> serializableTypes = new List<Type>();
// Look at all types in the assembly.
foreach(Type type in asm.GetTypes())
{
if (type.IsSerializable)
{
// Add the name of the serializable type.
serializableTypes.Add(type);
}
}
return (serializableTypes.ToArray());
}
The GetSerializableTypes method accepts an Assembly through its asm parameter. This assembly is searched for any serializable types, and their full names (including namespaces) are returned in a Type[].
In order to use this method to display the serializable types in an assembly, run the following code:
public static void FindSerializable()
{
Assembly asm = Assembly.GetExecutingAssembly();
Type[] serializable = GetSerializableTypes(asm);
// Write out the serializable types in the assembly.
if(serializable.Length > 0)
{
Console.WriteLine("{0} has serializable types:",asm.Location);
foreach (Type t in serializable)
{
Console.WriteLine("\t{0}", t.FullName);
}
}
}

you have to use regular expressions for something like this.
<br />
using System.Text.RegularExpressions;<br />
<br />
string linkPattern = "href\s*=\s*(?:""(?<match>[^""]*)""|(?<match>\S+))";<br />
Regex linkRegex = new Regex(linkPattern, RegexOptions.IgnoreCase | RegexOptions.Compiled);<br />
Match linkMatch = linkRegex.Match(page);
while(linkMatch.Success)<br />
{<br />
string link = linkMatch.Groups(1).Value.ToString();<br />
....
linkMatch = linkMatch.NextMatch();<br />
}<br />

Header proBarStatusUC = (Header) Page.FindControl("Header");
proBarStatusUC.Function1();
proBarStatusUC.Function2();
Header proBarStatusUC2 = (Header) Page.LoadControl("Header.ascx");
phPlaceHolder.Controls.Add(proBarStatusUC2);

I'm creating a software for painting.
the user can create an working area like photoshop does.
I use as working area a PictureBox.
So if the use decide to create a very big working area like 2000 px for 2000, it should be very slow then the user may decide to create other bigger and the PC memory could be not able to.
What do you advice me to do?

Hi All!!
The FolderBrowserDialog shows the New Folder button even when the ShowNewFolderButton property is set to false. The problem is not corrected in Visual Studio 2005 whereas the problem was present in Visual Studio 2003.
I just wanted to ask whether any one has found a work around for the problem faced.
Thank you
ENJOY!!

Im using VS2003, and that property works exactly as I expect Setting the property to false causes the "Make new Folder" button to be hidden.

Is you're Main function marked as STAThread? Sometimes this can cause bizarre behaviour. I came across something almost identical to this (if I remember correctly) and it was solved by adding a STAThread attribute to Main.

Hi all!!
I a bit confused on the expiration of a ticket, and a cookie.
I have the following code:
FormsAuthenticationTicket objTicket = new FormsAuthenticationTicket(
1, // version
Context.User.Identity.Name, // username
DateTime.Now, // issue date
DateTime.Now.AddHours(1), // expires every 1 hour
false, // don't persist cookie
strMemberRoles // member roles
);
And...
Response.Cookies["myCookie"].Expires = DateTime.Now.AddMinutes(5);
What happens if the user uses the site for exactly 1 hour and 1 minute. This means that the ticket and cookie has not expired? Does the cookie only expire 5 minutes of being on a page that hasn't been used for 5 minutes?
If the ticket only expires after an hour, what is the use of assigning it so long if the cookie expires after 5 minutes?
Please can someone help me!!

why we can only access xml file which is created under folder
project/bin/debug only.is there any way by which we can access file which is created in some other folder.

You should be able to access xml file or any other file type on any folder, provided you have access to the folder and files. Did you put in the full path (ie c:\mydata\xmlfilename.xml)?

In Visual Studio 2003, like I can avoid that the user does not change the size of the columns of a datagrid and listview?
Thank you and sorry for my english

Hi all!!
I have the following global variable in my globals.cs file:
public static readonly string REGEXP_ALPHANUMERIC_WITH_SYMBOLS = "[\\u00E8-\\u00EB\\00FCa-zA-Z\\d\\-',&.@#/ ]";
I use this for my regular expression. I want to add a \ to the string. I tried using \\, but when I use my regular expression it does not work. After creating my regular expression it looks like:
^[\\u00E8-\\u00EB\\00FCa-zA-Z\\d\\-',&.@#/\\ ]$
Please can someone help!!

Below is my C# class code
------------------
using System;
using System.Data.SqlClient;
using System.Configuration;
public class MyClass
{
static string sConnectionString ;
static MyClass()
{
sConnectionString = ConfigurationSettings.AppSettings["sConnectionString"];
}
static int ExecuteNonQuery(String sSql)
{
SqlConnection cnn = new SqlConnection(sConnectionString);
SqlCommand cmd = new SqlCommand(sSql,cnn);
cnn.Open();
int retVal = cmd.ExecuteNonQuery();
cnn.Close();
return (retVal);
}
}
-------------------
whenever i call ExecuteNonQuery method of above class(without instancing this class) i want the value of sConnectionString which is defined in Constructer. Please give me a solution.

i would rewrite it as following:
<br />
public static class MyClass<br />
{<br />
<br />
public static string ConnectionString {<br />
get {return ConfigurationSettings.AppSettings["sConnectionString"];}<br />
<br />
}<br />
<br />
public static int ExecuteNonQuery(String sSql)<br />
{<br />
SqlConnection cnn = new SqlConnection(ConnectionString ); <br />
SqlCommand cmd = new SqlCommand(sSql,cnn); <br />
cnn.Open();<br />
int retVal = cmd.ExecuteNonQuery();<br />
cnn.Close();<br />
return (retVal);<br />
}<br />
<br />
}<br />
Now from any calling class you can do the following:
<br />
int result = MyClass.ExecuteNonQuery("SELECT x FROM y WHERE B = C");<br />
string conStr = MyClass.ConnectionString;<br />
if you want the ExecuteNonQuery to return both the result and the connectionstring in once, create some new class that with two properties, Result and ConnectionString, and return that class from the ExecuteNonQuery method.
