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; }

Because of the unexpected shutdown, my outlook can not start up and it's trying to fix the storge files behind.
then I open IE and use OWA( outlook web access). as expected,there are lots of junk mail,:)so I press delete one by one, the email are dropped . however ,the screen does not refresh ,seems it send the delete command asynchronously. and the request/response reveived are kind of web-formatted xml. so Is owa the first web 2.0 app of microsoft?

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

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

Aim: I wanna guarantee that only signed assembly have the access to my class library. SO I make use of the .net StrongNameIdentityPermissionAttribute to protect my assembly. When testing ,I encounter the different public keys of a same public/private key pair.
1. Extract the public key from the keyfile
Sn -tp montaque.snk
the public key echos:
Public key is 0702000000240000525341320004000001000100eb3a0ffb39f8d13e553d77c40399287cb7f29e d6199da3daa9a31db7c437e0c550bae8e4bad69b7aad37ff9acc541166256d384176fe22ae6b1a 0f5204c8c8a5ba7c8f796506fb9f4621db157830e3faef0652a89ea30c3fe53b45033c7466a3ed a68d8d40b4909d03e91c6f72d43f1740c10d701e74c500b8c9f491c11ae2b90fd7494f824a7ebb f40a2aefc8886b8f7396ef3d0e5bf2d78c66db8b69a36fdc6ed378171d5837c43c871d0ce7c47b 61b53c36234f600072e8dfa17c13814eec657eac534c8fcd5291721f702e9b4e7d1b6c995af685 6018e624a4435eb3d4681f83c636e374d8cf7ec38829f0b68071ed7fdf2dc243b87aa62e1d8fcd d65fc9773c297f59d46d270e7ffadcb457abf1ed7a73734d17e41564a223703085318bb81b21ba 6e1724dbb32b4e79f10fc407ef835429014fe1e34b7c8e07316b5064757c47a1daba35cd3f9d53 ee99f6ee7c0a8a5e6c7ac7e56173b9a8e02a02b301a5415dfe2089e827ae372e4a5b65058a892d b654669485ea9e6238f5b4a69195d58cb345586c781e0f50a23fe67c6fdd7c766f867fed718bd4 98e8cd95dbcad5e48f0ebef977c779c71329aa6ab5c1c6596a7b8fb0df0c24ff05d967e2fa97e8 c9e0844074b7b7bc6f45fa86d4b55cd09c3bcab03f28670e5d9fa9ad1383eeb1bbe201e290b38d 18195d867ee066f10dd9277eaf60d45c737cbb301a955c88bf60b203e8b0ac13a887c0003d5d45 131c6a88a8c59a094ea69fa0440b4f78fe8bb5fa1b8957ae6ae9c9671e02b08cec48b42023d2d1 7c5ef152596caa2a890027
Public key token is 7a2a95f64f29bc4f
the key length is 1192
2. extract the public key of the signed assembly.
Public key is 0024000004800000940000000602000000240000525341310004000001000100eb3a0ffb39f8d1 3e553d77c40399287cb7f29ed6199da3daa9a31db7c437e0c550bae8e4bad69b7aad37ff9acc54 1166256d384176fe22ae6b1a0f5204c8c8a5ba7c8f796506fb9f4621db157830e3faef0652a89e a30c3fe53b45033c7466a3eda68d8d40b4909d03e91c6f72d43f1740c10d701e74c500b8c9f491 c11ae2b9
Public key token is 9bcbe75a245746b6
I am suprised that why two keys are not equal, does they have some relationship like mapping or hashing?

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.

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.

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?
the same question in http://dotnet247.com/247reference/msgs/1/5553.aspx

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.
