    - Read from COM port? I need to read messages from a device connected to a COM port with the following format: When the controller is configured to report events, it will transmit a new message every time the event occurs. The message follows the following format: XX <Message> {CR} {LF} {Terminator} . "XX" is the Message ID Number. Each type of report message from the controller has a unique ID number in a 2-digit hexadecimal format. Each digit will be a hexadecimal value (numbers 0-9 or letters A-F). When converted to decimal format, they represent the numbers 0 through 255. By reading these two bytes, a user program can quickly identify the type of message from the controller. . "<Message>" will contain a text description of the event. . {CR} signifies that a carriage return is sent. . {LF} signifies that a line feed is sent. . {Terminator} signifies that a single-byte terminator code is sent. The byte has a value 1d, which is the ASCII code SOH (this is NOT the number 1, which is ASCII value 49d). The terminator is provided to make it easier for a computer program to read and interpret the messages from the controller. What framework clases are best suited for reading this kind of messages from the device? Can you specify the terminator character which is at the end of each message? -- Olav Tollefsen Tag: Version Changes 1.0 to 1.1 Tag: 56862

    - Installutil.exe does not register windows service Hi, I have written a Windows Service (using C#) using the .Net framework and to install the same am using the Installutil.exe tool. However inspite of no errors returned in the InstallLog file the custom service does nto get installed. Am I missing something here... Also the following is logged in the InstallLog file... "No public installers with the RunInstallerAttribute.Yes attribute could be found in the d:\denz\service\xmlgenservice.exe assembly. Remove InstallState file because there are no installers." Do I need to reference the Windows installers here... (Think this is the missing link...) Any pointers will be appreciated... TIA, Denzil Tag: Version Changes 1.0 to 1.1 Tag: 56857

    - .armx? I've noticed on various msn.com webpages the .armx extension. Perusing various search engines has turned up nothing except for a single webboard thread which talked about msn.jp and someone's theory that it is a personal .NET extenstion system for MSN.com because you can easilly create your own extensions. Is this true? And if not? Just what is this? Some sort of new technology? I doubt they'd want to replace asp.net so soon, right?

    - ADO.net Hey, i am bit concerned about the architecture provided in the .net frame work for ado.net. The disconnected architecture does nor serves you best on the desktop application. As you are not connected to database and if any other changes the table in the database you are not notified or your side data is still older one. As it was not in ADO we use to set the recordset properties to our need and we were quite happy. but not now. Example: Dim rs as ADODB.Recordset TextBox1.databindings.add("Text",rs,"id") (X) which is not allowed by the .net frame work, as i am using the Recordset that is in ADO not in ADO.Net and its required interface is not present. But i want to do that ... as it is quite easy to use this structure. I think there is problem with Microsoft they dont even support there ADO properties in their .net TextBox or any other control. They should provide the Implementation of connected recordset or simply implement the IList interface or any other interface that is required for the data binding in .net fram work. thanx, Rizwan Ahmed Tag: Version Changes 1.0 to 1.1 Tag: 56843

    - TcpClient lost data timing anomaly Hi The platform: XP/pro on a dual Xeon 3GH processors I am using TcpClient class to communicate with a POP3 server. Short problem synopsis: a 'read' hangs even though there is data in the buffer (as evidenced by a network sniffer trace). Elaboration: I/O is done by getting the NetworkStream and doing a read for a whole buffer's worth (typically 1024) of bytes. The code looks for the NL (new-line char, '\n'), as a delimiter. If found, the text up to and including the NL is returned to the caller. Otherwise another read is performed and concatenated to the previous read's output, and the check for the delimiter repeats. On subsequent reads, if there was data left over from the previous read, it is processed for NL before any other reads are issued. I have used a network sniffer to determine that all the data is coming in. I have put a trace in my program to output to a file (serialized with a 'lock') all the output form all the read requests. I consistently find that one of the reads is able to get all but the last 3 bytes of a response from a server. The code dutifully returns all the text received and tries to do another read since the caller is looking for a '.\r\n' sequence (end-of-message). This read hangs (I use the debugger). When I change the buffer size the problem happens in a different message. If I make the buffer large enough, the problem goes away. The buffering code described above is working for thousands of messages that have split across multiple buffers or for short messages where multiple fit in the same buffer, so I'm pretty confident that it is splitting messages correctly and gluing together segments across network messages. My only conclusion is that something in the TcpClient (or deeper) is checking the socket and waiting for more data in a non-atomic manner. The problem shows up on my system because it is a fast dual processor system that can obviously do concurrent processing by multiple threads/processes. Has any one seen this kind of problem before? Any work-around? -TIA David Tag: Version Changes 1.0 to 1.1 Tag: 56822

    - Problems with GCHandle and AppDomains Greetings everyone. I am currently working on a multimedia application written in unmanaged code. As part on my next set of improvements, I would like to host the CLR in the application and allow third parties to extend the application and manipulate internal objects in the application through a "script" interop layer I provide written (on my end) in managed C++. The way my system is set up, from the default domain in my host, I instantiate the script harness using AppDomain::CreateInstanceAndUnwrap method and downcast the resulting object to a common interface that my application and the harness know about. I call a "run" method on the interface. In a test script I created, I register a callback object into the multimedia app. The unmanaged callback object contains a GCHandle to a delegate which it fires periodically on behalf of the unmanaged application based on certain timing parameters. Now, when the harness and my test script used to run in the default domain, everything worked like a champ. Now that the test script is in a different domain, when the unmanaged callback object dereferences the gchandle to invoke the delegate on the script, I get an ArgumentException with a description that reads: "Cannot pass a GCHandle across app domains". I've hit my head against the wall trying to get this to work for a while now with no success. Does anyone have any idea what I could be doing wrong? Thanks in advance for any help you can give.

    - Localization and multiple string resources Hello! I am looking at .Net localization. I happen to be using J# with VS 2003 but it could be any supported language. The LocalizedHelloWorld example from MSDN and VS shows how to localize a single .resources file. Here is a link to the J# version: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dv_vjsample/html/vjsamlocalizedhelloworldsamplesatelliteassembliesforconsoleapplications.asp The problem I have is I am working with an application that has several string resources per DLL. I have not been able to find a way to get it to work. The example loads a resource called "HelloWorld.Resources.MyResources". Each localized version is embedded in a DLL called "HelloWorld.resources.DLL". The trick seems to be that there can be only one such DLL. I have modified this sample and tried embedding two resources, MyResources.resources and MyResources2.resources, and also creating, for example, two French resources, MyResources.fr.resources and MyResources2.fr.resources, into the satellite assembly "HelloWorld.resources.DLL". But, when I request "HelloWorld.Resources.MyResources2" with the culture set to "fr", it fails to find the second French resource and falls back to the embedded MyResources2.resources. Does anyone know a way to make this work? Thanks in advance. Tag: Version Changes 1.0 to 1.1 Tag: 56803

    - Base Class Prop not hidden to Reflection Hello, I'm encountering an unexpected behavior when using the "new" modifier in a derived class to hide an inherited base class property. I use "new" intentionally so I can change the Type of the property in the derived class, and I can use the derived class as expected through standard instantiation. The unexpected behavior occurs when I try to set gather the PropertyInfo for the derived class property via Reflection. I get an AmbiguousMatchException as both the base class and derived class property implementations are found. Perhaps I don't fully understand the "new" modifier - I expected the base class member to be hidden completely when working with the derived class. I have included a code sample that illustrates the behavior. If anyone could explain this, I would be very interested in understanding. Thanks. using System; using System.Reflection; namespace TestHide { class foo { [STAThread] static void Main(string[] args) { Derived d = new Derived( "test" ); Console.WriteLine( "PropType:\t" + d.Problem.GetType().ToString() ); try { PropertyInfo p = d.GetType().GetProperty ( "Problem" ); } catch(AmbiguousMatchException e) { Console.WriteLine( "Error:\t\t" + e.Message ); PropertyInfo[] p = d.GetType().GetProperties(); for( int n = 0; n < p.Length; n++ ) { Console.WriteLine( "Name: " + p[n].Name + "\tType: " + p[n].PropertyType + "\tDecl: " + p[n].DeclaringType ); } } catch(Exception e) { Console.WriteLine( e.Message ); } } } public class Base { protected int _works = 0; protected object _problem = null; public Base(){} public virtual int Works { get { return _works; } set { _works = value; } } public virtual object Problem { get { return _problem; } set { _problem = value; } } } public class Derived : Base { public Derived(){} public Derived(string problem) { this.Problem = problem; } public override int Works { get { return base.Works - 1; } set { base.Works = value + 2; } } public new string Problem { get { return (string)base.Problem; } set { base.Problem = (string)value; } } } } Tag: Version Changes 1.0 to 1.1 Tag: 56755

    - DLL, memory leak, handles issues with TCP/IP. Hi, I have an application that uses a dll that we have written. This dll makes use of winsock2.h functions like WSAInitialise etc. all related to opening and closing tcp connections wrapped in our own dll commands. I pass the application handle to the dll.(this might be the issue i think) Problem is i am seeing a memory leak (handles go on increasing) when i run my application using functions from dll in a loop and its being caused by our implementation of tcp probably. However if i use the same low level commands which are interfaced with winsock commands i dont see the memory leak(handles dont increase) Is there something special about working dll and tcp/ip. I read somewhere that you need to create a hidden window internal to dll to post the messages. I hope someone gives me a helpful answer. I am going crazy trying to stop the increase of handles.

    - XML Serializer question... Hi, I have an array of structures I would like to turn into an XML string using the XML serializer. The problem I am running into is that I get an exception. Depending on what data type I set the serializer up with (my structure or ArrayList), I get either "Invalid Cast" or "...did not expect type <my structure> ..." Does anybody know how I can do this WITHOUT having to resort to using the SOAP formatter? It seems like a waste to put all of that extra stuff in my xml.

    - err.raise inside catch? I would like to use err.raise(x) within a catch block to send an exception back to the calling function or cain of functions. Is this ok to do? I know if i dont use try catch fail in the child function that it will send an exception to the calling function but i want to have error handling in all chain functions. any MSDN documentation on this?

    - Set system time Is there a .NET Framework class that can be used to set the local system time? I do not want to use the P/Invoke to call the SetSystemTime WIN32 API unless I need to. I would like to be able to do it from within the Framework. Thanks for you time, Dave Tag: Version Changes 1.0 to 1.1 Tag: 56714

    - Versioning compatibility hi all, In VB we used to have versioning by implementing a) No compatibility b) Project Compatibility c) Binary Compatibility how can the same things be achieved explicitly in .NET in context of all these three for CLR Components(managed Code). please guide us through the steps to implement managed component on client machine for newer version as well as older version. Scenario : I have made a class library in which there is a method Test(int a,int b) This class library is being called by client. 1) now I am altering the method (test) definition, so when would the client get the newer copie of the test method, how will system identify that which version has to be picked. 2) or I am altering the method (test) signature by providing new arguments, now when would the client get the newer copie of the test method. please guide us through the steps and provide me some resource on net. Please reply ASAP. bye AMIT PUROHIT Tag: Version Changes 1.0 to 1.1 Tag: 56712

    - MethodInfo Invoke - getting source line number after TargetInvocationException Hallo, I have a problem getting the line number of an exception thrown in an executable generated using ICodeCompiler (from a source text file) and then invoked. I catch the TargetInvocationException in Invoke, but line number of where the exception in the ICodeCompiler executable is thrown is missing! However assemblies referenced by this executable can show line numbers (if debug versions) All that is said regarding the code compiled is that the exception was at Main(). CompilerParameters.IncludeDebugInformation is set to True Source snippet shown below: Thanks for any help, Nick CompilerParameters cp = new CompilerParameters(assemblynames); cp.GenerateExecutable = true; cp.GenerateInMemory = true; cp.IncludeDebugInformation = true; TempFileCollection tfc = new TempFileCollection(); CompilerResults cr = new CompilerResults(tfc); cr = icc.CompileAssemblyFromFile(cp, fileName); If successful I invoke using: System.Reflection.MethodInfo m = cr.CompiledAssembly.EntryPoint; try{ m.Invoke(null, null); } catch(TargetInvocationException tie) { Console.WriteLine(tie.ToString()); Console.WriteLine(tie.InnerException.ToString()); } Tag: Version Changes 1.0 to 1.1 Tag: 56711

I have a simple aspx page that used to run properly in
framework 1.0. Now that I moved to 1.1 the validation
controls do no run. I just installed Framework 1.0 and
also changed the
config file so accept 1.0:
<configuration>
<startup>
<supportedRuntime version="v1.0.3705" />
</startup>
</configuration>

But still does not work. The page does run the control
validations.

Any ideas ?
Thanks,

Sergio
