    - lock statement Hi i have an important question about the lock statement. If i have object objA; object objB; and then object refObj = objA; or refObj = objB; if i do lock (refObj) { ... } will it be considered like lock(objA){ ... } or lock(objB){ ... } or it will use regObj to lock (so the next call to lock(objA) or lock(objB) will not block?

I get an exception when the method is invoked saying: "Object reference not set to an instance of an object". What could cause this problem? Does it have something to do with the AssemblyInfo file?

    - VB.NET to c# convert Hey all Our company recently started using .net and started in VB.NET. We've since changed to c#, but has some code already written in VB.NET. I'm looking for a converter that will just take vb.net and convert it into farely nice c#. I've found one or two, but they do some strange stuff and was wondering if there is a Microsoft converter or one generally accepted as being good by the community?

    - Timer triggering immediately In VisualStudio 2003 a System.Threading.Timer is created as follows: c# code: TimeSpan sleepTime = ... _timer = new Timer(new TimerCallback(run), null, sleepTime, TimeSpan.Zero); ... private void run(object state) { stopTimer(); ... } private void stopTimer() { if (_timer != null) { _timer.Dispose(); _timer = null; } } In certain cases the timer triggers immediately eventhough the sleepTime is several days from now but less than 2^31 milliseconds Whenever this has happened it seems as if the only way to get the framework to behave normally again is to reboot. Does the Knowledge Base article 814861 regarding an unhandled exception error occuring in the Timer control in Visual Studio .NET 2003 fix this problem, or are the problems not related at all?

    - datatable index being corrupted Hello All, I have a rather large cached dataset containing global application data for a relatively heavy travelled website. Its totally disconnected from the database, just acts as an in memory table. My problem is during periods of heavy server load, the index on the datatables appears to get corrupted.The stack trace errors on System.Data.Datatable.GetIndex. I can't duplicate this on my development machine, so I'm not real sure what is going on. I'm guessing since the datatables aren't thread safe, when the server is under load it is more likely that multiple threads will be modifying the datatable concurrently and possibly causing it to corrupt the index somehow. Anyone ever run into this? Should I make the write operations threadsafe? Could it be some other problem? Tag: Obtain Bitmap of a Graphics object Tag: 80867

    - Compiling resources into assembly Hi! My app consists of three parts: 1. Client app 2. A webservice with sourcecodefunctions 3. Local "end-user-compiled library" The user does like this: 1. Download small app from Internet 2. Start application and login to my service 3. Small app downloads source code and compiles an assembly for it to use So far so good. Everything works fine as long as I don't need any extra resources. For example: A Form with any Windows Forms control on it works fine. A form containg icons or an ImageList with icons doesn't work since I have to compile the resource into the assembly. I use the CompileAssemblyFromSourceBatch-function to create my assembly. I read somewhere that .resx-files could be entered in the string [] as a part of the code to compile but it doesn't work. My problem is that I don't have physical resx-files. Only as string from my service and I really dont want to create any files locally on the client computer. I know that I can use resgen to make .resource-files and then add csCompilerParameters.CompilerOptions = "/res:form.resource", but since I don't want to create files it's not an option either. In other words... how do I create my assembly using CompileAssemblyFromSourceBatch including my resx-files!!! Regards Kristian Here's how I do it. Pretty straight forward isn't it? // Create compiler csCodeCompiler = csCodeProvider.CreateCompiler(); // Add references CompilerParameters csCompilerParameters = new CompilerParameters(strLibraries, "ClientDownload.dll", true); // Generate a dll csCompilerParameters.GenerateExecutable = false; // Set tempfilescollection csCompilerParameters.TempFiles = csTempFiles; // Compile library csCompilerResults = csCodeCompiler.CompileAssemblyFromSourceBatch(csCompilerParameters, strCode ); return csCompilerResults; Tag: Obtain Bitmap of a Graphics object Tag: 80866

    - memory usage on terminal server I have a question about memory usage for compiled code of .net application. I think that traditional DLL or EXE code is loaded into memory only once and it's shared between processes and/or sessions. However, i am not sure if this mechanism can be used for .net applications. because from EXE or DLL file is loaded only MSIL code and this is JIT compiled in memory. And my question is if this compiled code is shared between processes too. I tried to find an article about this on MSDN, but i couldn't. so if you know something useful then let me know. I need to know this, because of of deploying .net applications to terminal server. And i would like to know, if it is better to write unmanaged code for terminal server, or for example use ngen.exe to precompile an application. thank you in advance Rasto Novotny Tag: Obtain Bitmap of a Graphics object Tag: 80812

    - MailMessage and address book entries Hi, I am using the System.Web.Mail.MailMessage class to generate and send email messages from my asp.net web app. I assumed that this was some simple interface to send mail using SMTP, but in the documentation for the "To" property it says: "Recipients in the semicolon-delimited list can be either email addresses or address book display names" Can someone explain to me what "Address book" means in this context? I can't find any other reference to address books in the framework documentation. Is there some kind of behind-the-scenes integration with outlook or exchange?

    - Invalid http request for .NET control Hi, I have a web page with a reference to a .NET control and I am getting a number of extraneous requests occurred that are related to the control To Digress ======= The html page contains a object tag that references a .NET control. <object id="mycontrol" class="http://server/virtualdirectory/mycontrol.dll#mycontrol"></object> The control is downloaded and displayed on the page. Please note: The control is always successfully displayed. The problem ========= Over ADSL, the request for the page seems to take a long time. When I used Ethereal to pack sniff the http traffic, I discovered that 10 invalid requests had been made to find the control. these range from http://server/mycontrol.dll to http://server/mycontrol/mycontrol.exe to http://server/bin/mycontrol/mycontrol.dll The last request is usually the correct http://server/virtualdirectory/mycontrol.dll Each request takes x seconds and the response is usually over 1500 bytes (file not found response). Hence the delay in downloading the page over ADSL. The Question ========= Has anyone encountered this problem before and is there a way to stop it from happenning Thanks in Advance Mark Tag: Obtain Bitmap of a Graphics object Tag: 80802

    - weird behavior ( browser or C# ) I have a problem with a new C# DHTML chat server I am making. First I'll describe the problem and then ill post the code. When I open 3 new instances of IE and connect the first client to localhost:9999 the first client status bas only displays: "opening page http://localhost:9999" It does not display "1" as expected. But when the 2nd client connects the 1st client displays "2" and the 2nd client displays "opening page......" Only when the 3rd client connects the 2nd client displays "2" in the status bar the first client displays "3" in the status bar and the 3rd client displays "1" in the status bar ( because the server now stoped listening and the program terminated. ) But when I restart the server and reuse the same 3 clients ( without closing them and opening new instances of IE ) the first client after connecting displays "1" in the status bar imediately ( as should be ). when connecting the 2nd client it imediatly displays "1" in the status bar and the 1st client dispays "2" in the status bar and when i connect the 3rd client the first client displays "3", the 2nd "2" and the 3rd "1" in the status bar. Why is this behavior. On Netscape the behaviour is somewhat similar. this is the C# code. // console application using System; using System.Net; using System.Net.Sockets; using System.Threading; using System.Collections; using System.IO; using System.Text; namespace AtomHTTPresponse { class AtomHTTPresponse { private const int MAX_CONNECTIONS = 3; private ArrayList prArrayListHTTPpipes = new ArrayList(); private TcpListener prTcpListener = new TcpListener( IPAddress.Parse( "127.0.0.1" ), 9999 ); static void Main(string[] args) { AtomHTTPresponse lAtomHTTPresponse = new AtomHTTPresponse(); Thread lThreadListener = new Thread( new ThreadStart( lAtomHTTPresponse.ListenerHandler ) ); lThreadListener.Start(); } private void ListenerHandler() { prTcpListener.Start(); for ( int lCntOuter = 0; lCntOuter < MAX_CONNECTIONS; lCntOuter++ ) { //lock ( this ) //{ Thread lThreadListener = new Thread( new ThreadStart( ConnectionHandler ) ); lThreadListener.Start(); //} } } private void ConnectionHandler() { TcpClient lTcpClient = prTcpListener.AcceptTcpClient(); NetworkStream lNetworkStream = lTcpClient.GetStream(); StreamReader lStreamReader = new StreamReader( lNetworkStream ); StreamWriter lStreamWriter = new StreamWriter( lNetworkStream ); HTTPpipe lHTTPpipe = new HTTPpipe( lTcpClient, lNetworkStream, lStreamReader, lStreamWriter ); prArrayListHTTPpipes.Add( lHTTPpipe ); lHTTPpipe.WriteToCLient( "<script language=\"javascript\">window.status = 0</script>" ); for ( int lCntInner = 0; lCntInner < prArrayListHTTPpipes.Count; lCntInner++ ) { ( prArrayListHTTPpipes[ lCntInner ] as HTTPpipe ).WriteToCLient( "<script language=\"javascript\">window.status = parseInt( window.status ) + 1</script>" ); } } } class HTTPpipe { public TcpClient puTcpClient; public NetworkStream puNetworkStream; public StreamReader puStreamReader; public StreamWriter puStreamWriter; public char[] puArrCharRequest = new char[256]; static string cStrResponse = "<script language=\"javascript\">window.status = 0</script>"; static string cStrHTTPheader = "HTTP/1.1 200 OK\r\n" + "Server: Microsoft-IIS/5.0\r\n" + "Date: Wed, 9 jan 2004 19:59:09 GMT\r\n" + "X-Powered-By: ASP.NET\r\n" + "Content-Type: text/html\r\n" + "Set-Cookie: ASPSESSIONIDASQSSARR=CCOBBLCBOLKOECFIANBGOBAI; path=/\r\n" // let it be for now. redundancy will be removed at a later time + "Cache-control: private\r\n\r\n"; public HTTPpipe( TcpClient iTcpClient, NetworkStream iNetworkStream, StreamReader iStreamReader, StreamWriter iStreamWriter ) { puTcpClient = iTcpClient; puNetworkStream = iNetworkStream; puStreamReader = iStreamReader; puStreamWriter = iStreamWriter; puStreamReader.Read( puArrCharRequest, 0, puArrCharRequest.Length ); // do nothing with the request but now we know we dont send a response before the request has been fully received.

    - Multiple References and Object Instantiation?? I am working on a application that has many custom made dlls. Actually, for this app each dll is a different form. I am able, with no problem to reference and instantiate them to use their public properties and methods with no problem. But, if one dll is trying to access another dll's properties (this does not work very good) the project tries to copy the dll to the directory which already contains the dll and the app will not compile. I have tried different ways to work around this, ie. Create a Class that instantiates all the forms from the dlls and reference the Class from whatever needs them. I can reference them just fine but cannot instantiate anything. Basically I am referencing a reference from a reference. Is there a way to Globally include all the dll's in the project using a config file or something so that once the dll is referenced, it is accessible by everything that is referenced from the Main App and Eachother? I don't believe this is very efficient and would greatly appreciate any suggestions, on better ways to accomplish this. The basic plan is to have all the forms independant of the Main App so that if a single form is changed all that is needed is to updated is the corresponding dll. Thanks, Chuck Tag: Obtain Bitmap of a Graphics object Tag: 80791

    - Runtime Security Policy question I THOUGHT I COULD BLOCK CODE ACCESS SIMPLY BY RESTRICTING ACCESS VIA THE FRAMEWORK CONFIGURATION MANAGER. MY EXPERMENT BELOW HAS CONFUSED ME. I attributed a DLL called "Filer" at the assembly level as follows: [assembly:FileIOPermission(SecurityAction.RequestMinimum,Unrestricted=true)] The Filer.dll contains a class called FileOpener. I compiled "Filer.dll" and referenced it from a Windows Form Project. In Framework Config Tool, I created a Code Group named "Test" as a child of the "All Code" code group at the Machine Level, Imported Filer.dll with a Hash Membership Condition, set Policy Level to Exclusive, and set the Permission Set to the "Nothing" Permission Set. I tested the Permission Level with the "Evaluate Assembly" option and was informed I had no Permissions. AS EXPECTED, I ran the form and got an System.Security.Policy.PolicyException when I instantiated the Filer.FileOpener class. I THEN REMOVED THE FILER.DLL ATTRIBUTE mentioned above ([assembly:FileIOPermission( SecurityAction.RequestMinimum, Unrestricted=true)]) ...from the Filer.dll and recompiled, rereferenced in the Form app, in Framework Config tool, reImported the Test Code Group hash membership condition and left all other Security Policy settings the same. I tested the Permission Level with the "Evaluate Assembly" option and was informed I had no Permissions. AS UNEXPECTED, I ran the form and DID NOT get an System.Security.Policy.PolicyException when I instantiated the "filer.dll" FileOpener class. In fact I got no Exception! I would expect no exception if I had made a mistake in reImporting the Filer.dll in the Framework Config Tool, but I didn't. In fact I reversed the process by reattributing the Filer.dll, recompiling, rereferencing in the Form app, in Framework Config tool, reImported the Test Code Group hash membership condition and left all other Security Policy settings the same. I tested the Permission Level with the "Evaluate Assembly" option and was informed I had no Permissions. AS EXPECTED, I ran the form and got an System.Security.Policy.PolicyException when I instantiated the Filer.FileOpener class. This leads me to believe that FRAMEWORK CONFIGURATION MANAGER Runtime Security Policy settings do not affect components that have not been attributed to request Permissions...and instead Permission Calculation only comes into play when code has been attributed with permission requests. This goes against what I read about the subject. Can you see what I am missing? Tag: Obtain Bitmap of a Graphics object Tag: 80788

    - Problems adding a reference with COM --converting to type .NET assembly failed Hello-- I'm in the process of coverting a VB6 app to VB.NET. My VB6 app is a help desk program, which scans a mailbox that we have set up for our help desk. We use Novell Groupwise and in my VB6 app, I added a reference to the Groupwise type library--no problem. But when I try to add a reference in .NET, the Groupwise library shows up in the COM list and when I go to add it, I get an error message saying: "A reference to GroupWare type library' could not be added. Converting the type library to a .NET assembly failed. Could not load type GroupwareTypeLibrary.DocumentType2Class from assembly Interop.GroupwareTypeLibrary, version 1.0.0.0." The reading I've been doing for the better part of a day suggests that the .dll needs to be registered with the GAC. I tried using regasm.exe but got a message saying it failed to load because it's not a valid .NET assembly. I don't know what I'm supposed to do to be able to get this reference added. Any help would be appreciated. Thanks. Molly J. Fagan Oklahoma Foundation for Medical Quality Tag: Obtain Bitmap of a Graphics object Tag: 80782

    - Serializing private members of a class I have a private instance of a object in a class i wish to include in the output of class serialization. The object is private because the contents cannot be modified outside the class but it is important that the contents of this private member are retained when the class is serialised. Can anyone tell me how i can include this private object instance into the serialised output. I know there are a number of xmlattributes you can apply to classes and class members, but i can't seem to find one that will allow me to do what i want.

    - Weird IE behavior Hi all, I am trying to make a very efficient C# DHTML chat server. But even the responding to clients bogles me. I will post the code after I have described the problem: When i open 3 new instances of IE and connect the first client to localhost:9999 all the status bar displays is: "opening page......." It does not display "1" as expected. But when the 2nd client connects the 1st client displays "2" and the 2nd client displays "opening page" Only when the 3rd client connects the 2nd client displays "2" the first client displays "3" and the 3rd client displays "1" ( because the programm now terminated. ) But when I restart the client and reuse the same 3 clients ( without closing them and opening new instances of IE ) the first client after connecting displays "1" imediately ( as should be ). when connecting the 2nd client it imediatly displays "1" and the 1st client dispays "2" and so on and so on. Is IE or C# so fucked up or am I doing something wrong? // console application using System; using System.Net; using System.Net.Sockets; using System.Threading; using System.Collections; using System.IO; using System.Text; namespace AtomHTTPresponse { class AtomHTTPresponse { private const int MAX_CONNECTIONS = 3; private ArrayList prArrayListHTTPpipes = new ArrayList(); private TcpListener prTcpListener = new TcpListener( IPAddress.Parse( "127.0.0.1" ), 9999 ); static void Main(string[] args) { AtomHTTPresponse lAtomHTTPresponse = new AtomHTTPresponse(); Thread lThreadListener = new Thread( new ThreadStart( lAtomHTTPresponse.ListenerHandler ) ); lThreadListener.Start(); } private void ListenerHandler() { prTcpListener.Start(); for ( int lCntOuter = 0; lCntOuter < MAX_CONNECTIONS; lCntOuter++ ) { //lock ( this ) //{ Thread lThreadListener = new Thread( new ThreadStart( ConnectionHandler ) ); lThreadListener.Start(); //} } } private void ConnectionHandler() { TcpClient lTcpClient = prTcpListener.AcceptTcpClient(); NetworkStream lNetworkStream = lTcpClient.GetStream(); StreamReader lStreamReader = new StreamReader( lNetworkStream ); StreamWriter lStreamWriter = new StreamWriter( lNetworkStream ); HTTPpipe lHTTPpipe = new HTTPpipe( lTcpClient, lNetworkStream, lStreamReader, lStreamWriter ); prArrayListHTTPpipes.Add( lHTTPpipe ); lHTTPpipe.WriteToCLient( "<script language=\"javascript\">window.status = 0</script>" ); for ( int lCntInner = 0; lCntInner < prArrayListHTTPpipes.Count; lCntInner++ ) { ( prArrayListHTTPpipes[ lCntInner ] as HTTPpipe ).WriteToCLient( "<script language=\"javascript\">window.status = parseInt( window.status ) + 1</script>" ); } } } class HTTPpipe { public TcpClient puTcpClient; public NetworkStream puNetworkStream; public StreamReader puStreamReader; public StreamWriter puStreamWriter; public char[] puArrCharRequest = new char[256]; static string cStrResponse = "<script language=\"javascript\">window.status = 0</script>"; static string cStrHTTPheader = "HTTP/1.1 200 OK\r\n" + "Server: Microsoft-IIS/5.0\r\n" + "Date: Wed, 9 jan 2004 19:59:09 GMT\r\n" + "X-Powered-By: ASP.NET\r\n" + "Content-Type: text/html\r\n" + "Set-Cookie: ASPSESSIONIDASQSSARR=CCOBBLCBOLKOECFIANBGOBAI; path=/\r\n" // let it be for now. redundancy will be removed at a later time + "Cache-control: private\r\n\r\n"; public HTTPpipe( TcpClient iTcpClient, NetworkStream iNetworkStream, StreamReader iStreamReader, StreamWriter iStreamWriter ) { puTcpClient = iTcpClient; puNetworkStream = iNetworkStream; puStreamReader = iStreamReader; puStreamWriter = iStreamWriter; puStreamReader.Read( puArrCharRequest, 0, puArrCharRequest.Length ); // do nothing with the request but now we know we dont send a response before the request has been fully received.

    - Accessing mapped drives from Framework 1.1 & COM+ I have a COM+ application that was written using Framework 1.0 and runs on Windows 2000. The COM+ app runs as domain user who has access to certain network shares. These shares are mapped on the server. There is no issue on Windows 2000. I installed the same app on Windows 2003 without installing Framework 1.0. Now the application says it cannot find the mapped drive. Do I need to change some configuration? Thanks.

    - how to make an object readonly in runtime? I have some data in a DataTable object that I'd like to put into a static class for the entire app to use, kind of like a cahced global value. The data in there should not change, but DataTable by default can be changed. Is there an easy way to make it read only. I can probably create my own wrapper class to accomplish this but hopefully there is a way to do this directly on the DataTable.

    - Best practice to lock DB SQLServer records in VB.NET application Hi all; I wonder if you have an opinion about this matter: Besides using "Version Number Approach" and "Saving All Values Approach" http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vbcon/html/vbtskPerformingOptimisticConcurrencyChecking.asp suggested by MS for solving lock problems, is there any other options to do this? In my opinion there's one limitation in these methods: if you loose your connection to your db for some reason while comitting the transaction, how can you be sure the lock is in the rigth state? Can you use threads to lock and unlock records? If so, can someone point me to some kind of a sample or tutorial to learn more about it? Urgent! Thanks in advance!

    - Type.GetType Access is denied Hello, The .NET application I have just installed at a client web site is throwing a strange error. At first the applications works without any problems, but after 10 mins or so Access denied error messages are thrown. The application, web based, late binds to a series of assemblies, none of which are in the GAC. I have configured the application to impersonate the IIS user and have set the user to have access to all relevant directories (wwwroot, wwwroot/bin, Microsoft.Net/framework/v1.1.4322) and disabled the index services service. After digging a little deeper it seems the error is thrown when calling Type.GetType, but like I mentioned earlier everything works fine but then suddenly dies. Can anybody think why this is the case and what I can do to resolve this irritating problem. Thanks Richard. Tag: Obtain Bitmap of a Graphics object Tag: 80690

    - Microsoft's DNP for Oracle. HELP!! (sorry for the x-post) Hello all, I am currently working on a project that uses MS's .net provider for Oracle. Now, here is where it gets WEIRD!!! for some reason when we run it in VS.NET's IDE it is fine, a previous build deployed (xcopy) onto a test PC is fine. However; when we have recently but a new build on it doesn't work. The only thing (and I ain't buying it) that my work mate says it is down to is that the path of the EXE has brackets in it!!! When we remove the brackets it is fine (something ain't right)!!!! Has anyone had a similar scenario or a explanation for this bizarre behaviour????

    - Serialized Hashtable Hi I've tried moving a serialized hashtable made in WinXP (std .Net framework), to a PocketPC device (Compact Framework). I've ran in to all kinds of problems, and have not been able to get this to work. The problem is not in the actual filecopy. I've tried the CompactFormatter (http://www.freewebs.com/compactFormatter/) for binary serialization. No luck when deserializing on the device. CF wont deserializa std framework, vice versa. I've tried XML serialization from opennetcf (http://www.opennetcf.org/library/OpenNETCF.Xml.Serialization.html). Got a problem since Hashtable implement IDictionary. For some reason. Is there another way to do this? Is there a reason why this should not work, or is it me who's doing this all wrong. If Hashtable in std framework is differently implemented than the Hashtable in CF, that would explain incompatibility when deserializing. But is that the case?

    - Binary Compatibility equivalent in .NET ? I have a client that insists that there be some sort of binary compatibility equivalent in the .NET assemblies I'm producing (converted from VB6 code). I understand their concern: while you don't *need* binary compatibility since you can just plunk in newer versions of assemblies (unlike in COM where the entire mess had to be recompiled if you didn't use binary compatibility), you might want some way to warn or prevent developers from making changes that may break an app using the assembly. I think this was the other main advantage of binary compatibility - it prevented thoughtless breaking changes thrown in all over the place. Any ideas?

The function should report the size of the file being written by the external program. How to achieve the 3rd point using .net framework 2003 only? Notes: for a certain external program .Net's FileLen reported file size is allways 0 until the file is closed.

    - Shared Static Variables in vb.net please? Does anyone know if MS has / is planning to introduce a shared static local variable to VB.net? I have had a few instances now where I thought this would be a tidy way to write some code. i.e. an instance method needs to access a shared (class) variable, and it is the only method that needs to access it. I really like the concept of static variables in vb.net, they make class definitions a lot tidier I think. Just a shame they called the keyword "static" as seems to confuse people. Cheers. Tag: Obtain Bitmap of a Graphics object Tag: 80649

In the Win32 API, if a Device Context contains a bitmap (presumably on which
the user is drawing), it is possible using the 'GetCurrentObject' API call
and the 'OBJ_BITMAP' ObjectType, to obtain a handle to the underlying bitmap.
It is then possible to reference this bitmap in calls to BitBlt, or other
associated Bitmap-processing routines.

How do I obtain a reference to the Bitmap object associated with a Graphics
object in .NET
