    - Changing a DataTables Schema Is it possible to use a DataAdapter to fill a DataTable, change the DataColumns of that DataTable (and maybe even it's name) and then commit those changes to the database (in my case SQL Server 2000)? Eg: [VB.NET] Dim dc As New SqlCommand("SELECT TOP 0 * FROM SomeTable", SomeSqlConnection) dc.CommandType = CommandType.Text Dim da As New SqlDataAdapter(dc) Dim dt As New DataTable da.FillSchema(dt, SchemaType.Source) dt.TableName = "NewTableName" dt.Columns("SomeColumn").ColumnName = "NewName" dt.Columns("AnotherColumn").DataType = GetType(String) dt.Columns.Add("NewColumn", GetType(Integer)) da.Update(dt) [C#] SqlCommand dc = new SqlCommand("SELECT TOP 0 * FROM SomeTable", SomeSqlConnection); dc.CommandType = CommandType.Text; SqlDataAdapter da = new SqlDataAdapter(dc); DataTable dt = new DataTable(); da.FillSchema(dt, SchemaType.Source); dt.TableName = "NewTableName"; dt.Columns["SomeColumn"].ColumnName = "NewName"; dt.Columns["AnotherColumn"].DataType = Type.GetType("System.String"); dt.Columns.Add("NewColumn", Type.GetType("System.Integer")); da.Update(dt); Tag: memory usage on terminal server Tag: 80811

    - 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: memory usage on terminal server 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: memory usage on terminal server 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: memory usage on terminal server 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: memory usage on terminal server Tag: 80782

    - OutOfMemoryException was thrown Hello everyone, I wrote a web service that monitorizes some directories and their contents. It returns a XML document as string. A web application calls this web service and parses the XML to display the status of directories graphically. It worked fine on Windows 2000. Then I transfered the web application on Windows 2003 and an OutOfMemoryException is thrown when there are too many files. Note this number of files excedeed is very low (order of 20). The web service still works on Windows 2003, but the web application causes the faults. The virtual memory settings are the same on 2000 e 2003.

    - 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.

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: memory usage on terminal server 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????

My old asp code successfully posted using a form action with fields such as &name="Joe Jackson" in .NET, if I pass this to the requeststream the cgi interprets some extra double quotes &name=""Joe Jackson"" If I leave off the quotes entirely the CGI script fails. Does anybody know whats the best way to build the requeststream so that it handles double quotes and spaces. Tag: memory usage on terminal server Tag: 80685

    - 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? Tag: memory usage on terminal server Tag: 80657

    - 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.

    - Bug in timers.timer ? Hi, Maybe Iâ??m doing something wrong but I canâ??t know what. Iâ??m using timers in my applications to do things after n seconds after do any other thing. Symptoms: After a random time the Elapse event just stop to be raised. I tried to debug and found something curious: Although I specified AutoReset property to False, at some time in the Elapse event the Enabled property came at value of True!!! After that happen, the Elapse event simply stop to rise. That means that my host applications freeze will waiting some work to be done based on that event. Please analyze this problem. I created a simple example that demonstrates that problem. The code is below this message. Just run it in debug mode, click Start button and wait till form turn red. At that time the problem I mentioned just happened. You can insert a breakpoint just after â??If T1.Enabled Thenâ?? line at â??T1_Elapsedâ?? sub and just after â??If T2.Enabled Thenâ?? line at â??T2_Elapsedâ?? sub to analyze what is happening. I couldnâ??t found an exact time that happened, so you can just start my example application and do other things while wait form turn red, or application stop at your break points. In my example I had a button to restart timer after it stops raising events. It seams that to restart raising Elapse events is just needed to set Enabled property to false and call start againâ?¦ But this behavior is not good! If I start many instances of this example app, them the error appears more offen. Is that a bug?

    - Installing .Net Framework Hello, although not a typical development problem per se, it is a situation that prevents me for developing in the .net framework v1.1. In a Windows 2000 Server with .Net Framework version 1.0.3705 installed, all asp & aspx files ran fine. I tried to install the newest version (1.1x) without uninstalling version 1.0 and installation seemed fine, aspx files were running OK. However, asp pages did not run, with an HTTP Error 500 (Internal server error). An uninstallation of the newest version, alongside a reboot that followed, corrected the problem. The particular server hosts numerous client asp pages, and all of them had the Internal server error, even when application protection was at the "low" setting. Please note that I am not an experienced developer, so I might have missed some tweaks that might make it work. What could have cause the problem?

    - Problems copying output dll's in a post build step I have a solution that has several projects, where many of the projects contain controls that are discovered at runtime, rather than direct reference (this is a requirement). Therefore, the 'copy local' reference copy mechanism of visual studio does not help me move projects around. My first attempt at setting up the solution was to set the output directory for the projects to a common directory. This did not work for the common dll's that are referenced by several projects because the dll is locked, presumeably because of intellisense. This was a while ago, so I don't remember all the exact problems, but they all had to do with projects being in use, preventing me to build. My second attempt (and current) is to let each project have its own output directory, and also copy the output in a post build step to a bin directory. This works most of the time. However, occasionally, the post build step will fail for some projects will fail, claiming the dll is locked - presumeably for the same reason as my first attempt. Why this sometimes works, and others not, I have no idea. My question: is there any way to reliably setup a project so that I can copy the output dll after it builds to another location. It seems like a simple need, doesn't it? Thanx... Tag: memory usage on terminal server Tag: 80586

    - Validating Email address with System.Text.RegularExpressions.RegEx Hi John, Using this regular expression: "\w+([-+.]\w+)*@\w+([-.]\w+)*\.([a-zA-Z]{2,4})" and testing it with an email address of dnlwhite@dtgnet.comabcdefg will come back and indicate that is a valid email address but the {2,4} should restrict the values after the '.' to no more than four characters. That's the first part of the neither I was referring to. Using the same expression, the email address dnlwhite@dtgnet.com1234 also returns that it is a valid email address but the [a-zA-Z] seems to indicate that there should not be anything other than alphabetical characters after the '.'. That's the second part of the neither. However, using the ^ and $ like you indicated solves the problem for me. Thank you for that! Doug Tag: memory usage on terminal server Tag: 80585

    - Bug on DataRow object´s GetColumnsInError method According to .NET Framework v1.1 Documentation, the DataRow object´s GetColumnsInError method gets an array of columns that have errors. This description made me think, develop and test a .NET Windows Application in a disconnected scenario. This application has a WindowsForm with a SqlDataAdapter object that fills a DataSet object. The resultant relational data is then displayed on a DataGrid control. At this time, the data can be modified. In this situation, various instances of the same .NET Windows Application running simultaneously can generate a System.Data.DBConcurrencyException when the SqlDataAdapter object´s Update method is called. Note that the SqlDataAdapter object is configured to use optimistic concurrency. If this exception occurs, the exception-handling structure´s Catch block can implement code to show, for example, a friendly message to the user detailing the accurate cells that had caused the errors. DataSet, DataTable and DataRow objects have the boolean property HasError that help developers to find rows with errors. The only information missing to show in the friendly message is the columns with these errors. To discriminate only the rows is not enough. To get these columns, the perfect method would be GetColumnsInError of the DataRow object. But concurrency exceptions do not set errors in DataColumns objects. In other words, the GetColumnsInError method do not return any columns. I assume that this behavior is a bug. Is there another way to reach this goal? Thank´s, Otávio F.

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
