    - Events in dynamic loaded assembly Hi all, I need a help with following problem. I need to create a menu from dynamic loaded assembly on the main form of my application. The menu is created succesfully, but the events of this menu, which are defined in the dynamic loaded assembly, are not raised. How can I raise them? Martin --- Odchozí zpráva neobsahuje viry.

    - Yahoo historical quote extraction problem I have the following method that retrieves quotes from the Yahoo historical quotes web page. According to their FAQ, there is no limitation on the number of quotes one may download, and because the problem seems to come and go, I'm concerned it may be a problem with my code. In particular, the problem seems to occur when I retrieve quotes over a long period of time. Normally the routine runs every night and downloads the previous days quotes. Occasionally, however, I'll download one or more years worth of quotes for several stocks. It's on these occasions when the code seems to fail. It doesn't fail the first time, though, and it won't necessarily fail on the stock that I'm retrieving multiple quotes from. The exception that is thrown is: "System.Net.WebException: The underlying connection was closed: The server committed an HTTP protocol violation." The exception is thrown at wrq.GetResponse(). Once I get this response, I can no longer receive any quotes. My only two options appear to be to drop the connection and reconnect (dial-up), or wait about an hour. I originally thought it was because I was going through a machine using Internet Connection Sharing, but then I did it directly to the internet without a proxy, and the same problem occurred. Anyone have any ideas? Code follows: public QuoteList GetQuoteHistory(Stock StockOb, DateTime StartDate, DateTime EndDate) { if (StartDate.Year < 1970) { StartDate = new DateTime(1997, 1, 1); } bool done = false; int tryCount = 0; QuoteList list = new QuoteList(); while (!done) { // Build url query string string url = @"http://" + yahooIP + @"/table.csv?a=" + ((int)(StartDate.Month - 1)).ToString() + @"&b=" + StartDate.Day.ToString() + @"&c=" + StartDate.Year.ToString() + @"&d=" + ((int)(EndDate.Month - 1)).ToString() + @"&e=" + EndDate.Day.ToString() + @"&f=" + EndDate.Year.ToString() + @"&s=" + StockOb.Ticker + @"&y=0&g=d&ignore=.csv"; WebRequest wrq = null; Stream strm = null; StreamReader sr = null; try { wrq = WebRequest.Create(url); wrq.Timeout = 30000; wrq.Proxy = WebProxy.GetDefaultProxy(); strm = wrq.GetResponse().GetResponseStream(); sr = new StreamReader(strm); } catch(System.Exception ex) { if (null != sr) { sr.Close(); } if (null != strm) { strm.Close(); } // Check to see if the operation timed out. If it did, // retry a couple of times. if ("The operation has timed-out." == ex.Message) { tryCount++; if (tryCount > 2) { return null; } continue; } else { return null; } } string line; try { // If there's no day, close out. if (null == (line = sr.ReadLine())) { return null; } while (null != (line = sr.ReadLine())) { // Parse quote data nad add the quote if it's not already in the // list of quotes char[] splitCh = new Char[1]; splitCh[0] = ','; string[] items = line.Split(splitCh); Quote quote = new Quote(); quote.QuoteDate = Convert.ToDateTime(items[0]); quote.OpenPrice = (float)Convert.ToDouble(items[1]); quote.HighPrice = (float)Convert.ToDouble(items[2]); quote.LowPrice = (float)Convert.ToDouble(items[3]); quote.ClosePrice = (float)Convert.ToDouble(items[4]); quote.Volume = Convert.ToInt32(items[5]); if (false == list.ContainsKey(quote.QuoteDate)) { list.Add(quote.QuoteDate, quote); } } } catch(System.Exception ex) { Trace.WriteLine("Unknown exception processing request: " + ex.ToString()); } finally { // Close everything nice and clean sr.Close(); strm.Close(); done = true; } } return list; } Tag: How to write a compiler for .NET?

    - How to convince client to migrate from ASP to ASP.NET My client have an application completly written in ASP and SQL Server. It's very big web application(Approx 250 ASP pages), It has all Validation rules, Business Rules and Data Access Rules embaded in ASP, even no stored procedures all database call with hard coded SQL. Is this possible that above web application can handle more than 5000 users? they are expecting to handle 1 million user? I know that above design is not good, Now How do convince my client to migrate from ASP to ASP.NET? I am new to .NET, Could you please tell me or send me link to an .NET based Architecture or really good advantages of .NET from business point of view. So client can think of scrap ASP application over new developement. Tag: How to write a compiler for .NET? Tag: 51562

    - Services.exe + handles leak (?) + windows 2000 server sp4 Hello, Im faced with the following problem. I have a client-server application using remoting, and running both client and server on the same machine for a few hours almost "kills" my windows2k server. I guess it has something to do with some sort of leak somewhere, maybe even outside my own applications. When i look at the memory usage pattern of my applications in the task manager i dont see anything strange, memory seems to get released properly (VM size+normal mem size). But when i look at how many handles are being used, i notice that the amount seems to increase for services.exe. About 20 handles per second are added to the total. Closing down my applications does not reduce the amount of handles used by services.exe at all. Another point is that the overal memory usage as shown by the task manager does increase up to the point where the system is unable to function properly, but no application seems to holding on to it. Yesterday i even got this message in the event log after a few hours: Event Type: Error Event Source: Srv Event ID: 2020 The server was unable to allocate from the system paged pool because the pool was empty. The client-server app uses sql-server, remoting, transfers files with tcp sockets, retrieves and stores files from a share. In my setup everything runs on the same machine (sql, shares, client, server). Is there any way i can investigate where these handles are used for? Or maybe someone has suggestions what to do to pinpoint where this leak is? Tag: How to write a compiler for .NET? Tag: 51560

    - Threading Issue Hello, I have several questions regarding the thread in .Netframework. 1. LocalDataStoreSlot Is there anyway to free an unnamed LocalDataStoreSlot? I am confused that I can only free NameLocalDataStoreSlot. 2. Is there anyway to get the collection of all the LocalDataStoreSlot allocated by current thread? And free them? 3. Talking about the ThreadPool, what happened to LocalDataStoreSlot when it's put into the pool? I want to free all the LocalDataStoreSlot before the thread is put into the pool or after it's waken up from the pool. Thanx. Tag: How to write a compiler for .NET? Tag: 51504

    - HttpWebRequest to ASPX for Postback I am working with the HttpWebRequest agains a simple aspx page that I created. The page has two panels one for the input of two html input boxes and the secone panel that displays the values of the input boxes on postback. I make my first web GET request like this: objRequest1 = (HttpWebRequest)System.Net.HttpWebRequest.Create(uri); objRequest1.Method = "GET"; objRequest1.ContentType = "text/html"; objRequest1.CookieContainer = new CookieContainer(); objRequest1.AllowAutoRedirect = true; objResponse1 = (HttpWebResponse)objRequest1.GetResponse(); sr = new StreamReader(objResponse1.GetResponseStream()); result = sr.ReadToEnd(); sr.Close(); I then receive a session cookie that I put in my 2nd request like this: string postData = "txt_name=tim&txt_address=261 Trailway" objRequest2 = (HttpWebRequest)System.Net.HttpWebRequest.Create(uri); objRequest2.Method = "POST"; objRequest2.AllowAutoRedirect = true; objRequest2.ContentLength = postData.Length; objRequest2.ContentType = "application/x-www-form-urlencoded"; objRequest2.Timeout = 100000; objRequest2.CookieContainer = new CookieContainer(); objRequest2.CookieContainer.Add(objResponse1.Cookies); myWriter = new StreamWriter(objRequest2.GetRequestStream()); myWriter.Write(postData); objResponse2 = (HttpWebResponse)objRequest2.GetResponse(); sr = new StreamReader(objResponse2.GetResponseStream()); result = sr.ReadToEnd(); sr.Close(); I am hoping this 2nd request trigger the postback and therefore the output data in the 2nd panel but it does not.

    - Interception , Remoting, & ContextBound objects Existing Scenario We have a windows application that is set up to either run in direct mode or to be remoted. When in remote mode, our business tier class and data tier classes would reside on an application server. These classes are all ContextBound. We have also developed a custom transaction component that uses interception so that when our SAO (server activated object) is instantiated on the server via the first method call against our class, we intercept the call and can begin our database transaction. The transaction would be completed when the method is exited. The SAO is registered on the server as a SingleCall object. A local proxy is created on the client. Issue The interception mechanism works fine when we run in direct mode. However, when we are remoted we have a problem. I have done some research and it appears that the .Net framework is calling InitializeLifetimeService against the AppDomain prior to invoking our method call. After looking at Rotor and the LeaseLifeTimeServiceProperty in the lifetimeservices.cs file, it appears that our object is not considered a single call object because it is ContextBound and remoted. Because of this, InitializeLifetimeService is called which is not the behavior we want because we have registered our server object as SingleCall. This behavior causes our interception to intercept the InitializeLifetimeService call. Ultimately, a database connection is opened, database transaction started, database transaction rolled back, and database connection closed around the InitializeLifeTimeService method call. After that call, our method is executed but the sinks have already been closed so we have no database connection to work with and no transaction to work with. Below is a pictorial of the scenario: If we use the new operator (local object) inteception works like the following: StartMySink->object Call->EndMysink But if use Activator StartMySink->IntializeLifeTime-EndMySink-Object Call Tag: How to write a compiler for .NET?

    - Timeout on HttpWebRequest.GetRequestStream() I have the following code that invokes a web service: HttpWebRequest request = (HttpWebRequest)WebRequest.Create(wftUrl); request.Method = "POST"; request.ContentType = "application/x-www-form-urlencoded"; // Prepare the request stream StringBuilder requestContent = new StringBuilder("WFTXMLFEED="); requestContent.Append(HttpUtility.UrlEncode(document.OuterXml)); byte[] encodedRequest = Encoding.UTF8.GetBytes(requestContent.ToString()); request.ContentLength = encodedRequest.Length; using (Stream requestStream = request.GetRequestStream()) { requestStream.Write(encodedRequest, 0, encodedRequest.Length); requestStream.Close(); } The previous code works fine most of the time, but every once in a while a WebException indicating a timeout is thrown in the GetRequestStream() call. A similar application using XMLHTTP (COM interfaces) never causes a timeout, so I doubt it is a problem on the web service side... Anyone who has an explanation for why this might be happening, or more importantly, a solution for this problem, I would appreciate it if it is posted here...

    - Bug in C# scoping rules? Am I missing something there and just being a bonehead or what? When I compile the code below, the compiler warns "A local variable named 'foo' cannot be declared in this scope because it would give a different meaning to 'foo', which is already used in a child scope to denote something else". I can't have PREVIOUS foo uses in nested scopes? What am I missing here?? I guess the compiler is not smart enough to see that the last foo doesn't have any nested foo declarations after it. ^%$@!*^&! static void Main(string[] args) { if (true) { int foo = 3; } if (true) { int foo = 57; } int foo = 5; // THIS LINE IS FAILING COMPILER "Compiler Error CS0136" Console.WriteLine(foo); } Tag: How to write a compiler for .NET?

    - Clearing "object browser" cache in VS.NET I'm having strange problems with VS.NET. When trying to go to definition, sometimes I get dropped into the object browser with the top assembly highlighted, rather than going to the definition in my source code.

    - Regular Expressions for email address (lengthy) This is a multi-part message in MIME format. ------=_NextPart_000_0077_01C34741.5A469F90 Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable I've looked around for awhile now for a solid email regexp string and = there doesn't seem to be a consensus on what such a pattern would look = like. A common approach is something along these lines: ^[a-zA-Z_0-9\.\-]+@[a-zA-Z_0-9\-]+(\.([a-zA-Z_0-9\-])+)*[a-zA-Z]{2,4}$ However, in researching the W3C documentation (RFC822 to be specific - = http://www.w3.org/Protocols/rfc822/#z66), I determined this is not = consistent with those specs and so I've come up with the following = approach. Could others look this over and offer feed back? Thanx. Per RFC822, an email address matches this pattern: LOCAL-PART @ DOMAIN The definition for LOCAL-PART is: word *("." word) Or in other words, a pattern of characters delimited by periods. The = definition for "word" is either a "quoted-string" or an "atom". A "quoted-string" is pretty much what it sounds like: a pair of double = quotes enclosing a text string consisting of zero or more characters. = The characters can either be "qtext" or a "quoted-pair". For qtext = characters, the only limitations is that they may not be a double quote, = a back slash or a CR (ASCII 13). A quoted-pair is "\" followed by any = character. An atom on the other hand is a string of zero or more chararacters that = is best described by what's disallowed rather that what's permissible. = An atom may contain any character except the following: control chars (ASCII 0 to ASCII 31{HEX: x1F}) space char (ASCII 32 {HEX: x20}) any of the following "special" characters: ()<>@,;:\".[] In my opinion, that allows for some genuinely odd possibilities for the = local part of email addresses that are both counter-intuitive and = unlikely in the extreme: "a quoted string containing \"()<>@\" followed = by".a-string_of#atom~characters.followed/by~"another quoted string" Therefore as a practical matter, I'm limiting the LOCAL-PART of the = email addresses to either a single quoted-string or one or more atoms = delimited by periods. Further, I've chosen to limit the contents of a = quoted-string to qtext only and make no provision for quoted-pairs. I believe a qtext string can be expressed as: [^"\x0D\\] and a quoted-string therefore as: ("[^"\x0D\\]+") The alternative way to express the LOCAL-PART of an email address is by = one or more strings of "atoms" that are delimited by periods. I believe a atom can be expressed as: [^\x00-\x20\<\>\[\]\\,;:\."@]+ An allowable period delimited string of atoms would therefore consist of = at least one string of atoms with at least 1 allowable character = followed by a zero or more stings of atom characters preceded by period = (like so): = [^\x00-\x20\<\>\[\]\\,;:\."@]+(\.[^\x00-\x20\<\>\[\]\\,;:\."@]+)*= This means the LOCAL-PART of the email address (in the somewhat limited = implementation described above) can be represented as a quoted string or = a combination of 1 or more atoms separated by periods = ^(("[^"\x0D\\]+")|([^\x00-\x20\<\>\[\]\\,;:\."@]+(\.[^\x00-\x20\<= \>\[\]\\,;:\."@]+)*)) The DOMAIN portion of the email address is another creature altogether. = A domain consists of one or more sub-domains that are delimted by = periods. A sub-domain is either a string of 1 or more atom characters OR = an IP address The problem with this approach is it allows for multiple IP addresses to = be concatenated with other IP addresses, atom strings or both. In theory = then, the following is permissible: 0.0.0.0.1.1.1.1.abc.xyz.99.99.99.99.999.com Clearly not a good idea. Of course, an IP address is a collection of = stings of atoms separated by periods, so it raises the question should = we even attempt to screen for them? As it happens, if you allow for a = list of period separated atom strings you automatatically accommodate an = IP address even if it is invalid (e.g.: 999.999.999.999).

From what I have uncovered, the worker process aspnet_wp dies abruptly after a webform is serviced. For every page request, it creates a new aspnet_wp process(instantiates it anew).The IIS instance was recycled rarely so it may not becoz of it. Becoz of this I have been unable to debug my application using the debugger and it doesn't hit any of the breakpoints. It also flushes out the static variables due to this.

    - Extending Web Controls All, We have a need for a drop down combo that the user can type into and autocomplete. I see both the server side and HTML web controls don't allow either function. Is there an easy way to add such capability without creating a composite control? I have see the ones where a user types into the text box and the matching begins below or next to the text box in the list or combo. Unfortunately, however, we really want to keep the functionality as similar as possible to our Win32 application. Having an OnKeyDown and OnKeyPress event would be nice as well...

    - NonSerialized System.Diagnostics.Process member I have a Serializeable class with a public member variable of type System.Diagnostics.Process. I don't want to serialize this, nor is it possible to serialize it. So I added the [NonSerialized] attribute to the type. But, I'm still getting an exception that I am trying to serialize the Process class. To be specific: System.InvalidOperationException: The type 'System.Diagnostics.Process' cannot be serialized because its parameterless constructor is decorated with declarative security permission attributes. Consider using imperative asserts or demands in the constructor. If I change the variable to private instead of public then it works, but I need this to be public. I tried using a private variable with a public, read-only property and it tries serialize it. I tried wrapping the Process member inside a non-serialized class and it tries to serialize it. I am using serialization with MSMQ and have not tried serializing to a file. Tag: How to write a compiler for .NET? Tag: 51366

    - Assembly Version Numbers - Reset or change in project Hello all - This seems to be a sticky issue. I've read all the articles I could find on dotnet assemblies and versioning - and the concensus seems to be to manually version your assemblies. The question I have is - is there a way to change the version number of an already referenced assembly in a project. An example would be when I created a project, I referenced version 1.0.1 of assembly A - then someone changed assembly A and the new version number is 1.0.2 - but my project still referenaces version 1.0.1 and gives me a warning about copying the asembly to the run directory. Somehow my project knows the version number of the assembly it was using, and is not letting it go (even after deleing all references and rebuilding the project) Any ideas?????

    - Java vs. .Net support for Oracle Java JDBC defines four types of database drivers. A type 4 driver is a native protocol, fully Java-enabled driver. For Oracle, this means the driver is written to the socket based protocol supported by Oracle's TNS Listener. Oracle's type 4 driver for Java has been widely used in the Java community since it does not require an Oracle client to be installed on each workstation. A quick look at Oracle's downloads suggests they aren't making it easy for .Net developers. For Java they provide both type 2 and 4 drivers, where their type 2 driver even has a small 200K download that installs the necessary OCI libraries for JDBC only. However, for .Net they only provide a 75MB Oracle data provider for .Net that requires the Oracle client to be installed, and also comes with a large, cumbersome, non-redistributable installation. Is Oracle or Microsoft planning to rectify this situation by providing an equivalent to a Java type 4 driver for .Net? It seems a pre-requisite for commercial software vendors to write .Net applications that interact with Oracle. Joe Tag: How to write a compiler for .NET? Tag: 51331

To do this I did what this MSDN article says: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vsintro7/html/vxurfprojectfoldernotsecuredialogbox.asp And it does not work, I also tried writing file://<servername>/<share/* and it doesn't work either!

Since I'm interested in formal languages I've decided to write a simple
compiler for .NET for my studies.
I would like to be able to use the .NET class library too (especially
windows forms).

Could you give me an idea where should I start from? Probably I have to
qualify myself as a beginner, so too advanced stuff might be not clear
to me yet. What would you recommend in that case?

Thank you!

I'm not sure, but writing a compiler always was 'advanced stuff'...

For .NET compilers, it is best to start learning
the CLR and MSIL:

Zingam,

Thomas and Jay gave you reference to good material, so you want to check
those out to begin with. I am working on a compiler targeting the .NET
Framework too, and if you already have some experience with writing
compilers you shouldn't have too many problems. The MSIL is very powerful
and way easier to target than a regular CPU.

I would recommend you to read John Gough "Compiling for the .NET Common
Language Runtime (CLR)"
(http://www.phptr.com/browse/product.asp?product_id={1590B1B8-35AB-484B-B231
-6D40E8D2A60D}), it's a little too much academic here and there but it was a
great source of information. I would also recommend you to read Jason Bock
"CIL Programming: Under the Hood of .NET"
(http://www.apress.com/book/bookDisplay.html?bID=88) if you are interested
in the results produced by different compilers (mainly C# and VB.NET), which
can be a good source of tips.

Don't forget the good old ILDASM (part of the .NET Framework SDK), and Lutz
Roeder "Reflector for .NET" (http://www.aisto.com/roeder/dotnet/). Reverse
engineering is very useful when you are not sure how to implement a
particular feature of your language.
