Invalid file name for monitoring: XXX path

Montaque — Thu, 08 Jun 2006 03:20:00 GMT

In .NET 1.1 , If you write code like this

Cache.Add("key",DateTime.Now.ToString(),new System.Web.Caching.CacheDependency(@"C:/Common.config"),System.Web.Caching.Cache.NoAbsoluteExpiration,System.Web.Caching.Cache.NoSlidingExpiration,System.Web.Caching.CacheItemPriority.Default,null);

please pay attention to the filename, even this file path is valid and you will always get the error that say invalid file name for monitoring.

So what happend? Permission? Or Any IIS Lock Software?

hehe, the problem is the you must write a valid file path like \\Server\A.txt

or C:\\Yourfile.path , So the problem is that .NEt 1.1 determine the file path via the following code

internal static bool IsAbsolutePhysicalPath(string path)
{
      if ((path != null) && (path.Length >= 3))
      {
            if (path.StartsWith(@"\\"))
            {
                  return true;
            }
            if (char.IsLetter(path[0]) && (path[1] == ':'))
            {
                  return (path[2] == '\\');
            }
      }
      return false;
}

So change your filepath to C:\Common.config will ease the exception.ha .

this issue has been fixed in .net 2.0,here is the code

internal static bool IsAbsolutePhysicalPath(string path)
{
      if ((path == null) || (path.Length < 3))
      {
            return false;
      }
      if ((path[1] == ':') && UrlPath.IsDirectorySeparatorChar(path[2]))
      {
            return true;
      }
      return UrlPath.IsUncSharePath(path);
}

which char is a valid directory separator? like thi

private static bool IsDirectorySeparatorChar(char ch)
{
      if (ch != '\\')
      {
            return (ch == '/');
      }
      return true;
}

Sometimes, Hello world does not work;)

Montaque — Thu, 30 Dec 2004 15:40:00 GMT

I add a web method to existing web service, which return array of arraylist as the result.

then everything workes worse, the client can not invoke either of the web method

here is a simple code

public service1: WebService
{

public service1()
{
}
        [WebMethod]
        public string HelloWorld()
        {
            return "Hello World, I am running in montaque notebook .NET";
        }

        [WebMethod]
        public ArrayList [] TestArrayList()
        {
            ArrayList [] ar=new ArrayList[1];
            ar[0].Add(1);
            ar[0].Add(2);
            return ar;
        }

}

when I test the code in the .net latest build ,40903, get the same result

Remember to invoke FlushFinalBlock()

Montaque — Fri, 09 Apr 2004 11:49:00 GMT

When encrypting a stream with System.Security.DesCryptoServiceProvider, code sniipt like the following.

Byte []EncryedText=Convert.FromBase64String(this.textBox3.Text) ;

System.IO.MemoryStream EncryptedStream=new System.IO.MemoryStream(EncryedText);

System.IO.MemoryStream OutMS=new System.IO.MemoryStream();

EncryptedStream.Seek(0,System.IO.SeekOrigin.Begin);

System.Security.Cryptography.DESCryptoServiceProvider x_des=new DESCryptoServiceProvider();

//??

   x_des.IV=m_IV;
   x_des.Key=m_Key;


   //???
   System.Security.Cryptography.CryptoStream encryptStream =new CryptoStream(OutMS,x_des.CreateDecryptor(),System.Security.Cryptography.CryptoStreamMode.Write);

encryptStream.Write(EncryedText,0,EncryedText.Length);
encryptStream.FlushFinalBlock();

   Byte[] outText=new byte[(Int32)OutMS.Length];
   OutMS.Seek(0,System.IO.SeekOrigin.Begin);
   //???????
   OutMS.Read(outText,0,(Int32)OutMS.Length);
   MessageBox.Show(System.Text.Encoding.Unicode.GetString(outText));

if the FlushFinalBlock is missed, you probably will not get the full encrypted text

2. extract the public key of the signed assembly.

Public key is

Public key token is 9bcbe75a245746b6

I am suprised that why two keys are not equal, does they have some relationship like mapping or hashing?

Message Queuing by MQSeries with C#

Montaque — Fri, 02 Apr 2004 10:01:00 GMT

MSMQ is the well-known Message API for windows developers. You can use MSMQ API directly by using System.Messaging class. Sometimes user needs to use IBM MQSeries especially for mainframe developers. IBM is providing a set of APIs Dotnet support pack using this we can access MQSeries. In this article I will explain the way to get and put messages using MQSeries and also will show the way to identify a particular message in queue of messages.

First of all we need to install the MQSeries Server in Windows 2000 server and need to install the MQSeries Client and Dotnet support pack in the client machine. Then we need to create QueueManager, Queue and Channel in MQSeries Server.

You can download the Dotnet support pack at this link.

Authorization and Profile Application Block

Montaque — Thu, 01 Apr 2004 13:51:00 GMT

The Authorization and Profile Application Block is a reusable code component that builds on the capabilities of the Microsoft .NET Framework to help you perform authorization and access profile information.

The Authorization and Profile Application Block provides you with an infrastructure for role-based authorization and access to profile information. The block allows you to:
? Authorize a user of an application or system.
? Use multiple authorization storage providers.
? Plug in business rules for action validation.
? Map multiple identities to a single user.
? Access profile information that can be stored in multiple profile stores.

using the Indexing Service with .Net

Montaque — Thu, 01 Apr 2004 13:32:00 GMT

What is the Indexing Service?

Microsoft Indexing Service is a service that provides a means of quickly searching for files on the machine. The most familiar usage of the service is on web servers, where it provides the functionality behind site searches. It is built into Windows 2000 and 2003. It provides a straightforward way to index and search your web site.

Setting up the Indexing Service is explained at windowswebsolutions.com and will not be covered here.

Connecting to the Indexing Service

The Indexing Service exposes itself to the developer as as ADO.Net provider MSIDXS with the data source equal to the indexing catalog name. For example, the connection string used in searching this site is

Provider="MSIDXS";Data Source="idunno.org";

As with any other ADO.Net provider you use the connection string property of the System.Data.OleDb.OleDbConnection object.

using System.Data.OleDb;
protected OleDbConnection odbSearch;
odbSearch.ConnectionString =
"Provider= \"MSIDXS\";Data Source=\"idunno.org\";";
odbSearch.Open();
// Query and process results
odbSearch.Close();

You can also use the connection string in Visual Studio by dragging and dropping an OleDbConnection onto your asp.net page and setting the ConnectionString property in the Properties tab.

Passing a session id to the server

With a remoting service running in IIS I can access the session state, user,
application, etc using the RemotingService class.

What is the best way to pass a session from a console client to the server?
I assume this must be done with the HTTP header, but what is the best way to
do this?

Microsoft's top-secret code is leaked

Montaque — Sat, 14 Feb 2004 11:55:00 GMT

Windows source code is Microsoft’s crown jewel, one that is guarded jealously. The company has to know exactly what source code is shared with partners and when.

Some background: At one time, Microsoft shared portions of the Windows NT and 2000 source code with two partners working on software tools that would allow other software developed for Windows to run on Unix. If I recall correctly, the amount was 8 million or so lines of code for one operating system.

That works out about right for the size of the leak, 13.5 million lines of code, according to people who have seen it. The timing fits, too, considering the apparent age of the code and when the partners had access to it. Folks who have seen the source code told me the code date appears to be July 25, 2000, which would be about right for Windows 2000 Service Pack 1.
