    - 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. What am I doing wrong? Thank for you help. Tag: Threading Issue Tag: 51500

    - 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: Threading Issue Tag: 51499

    - Serialization bug between framework 1.0 and 1.1 I read on the remoting group (which I'm not posting to because it isn't managed?) that there was a but in Framework 1.1 that didn't allow for proper serialization of the sortedList class between framework 1.0 and 1.1. Is there any status on getting this fixed as I am faced with a major problem due to this issue. Thanks, B.J. Tag: Threading Issue Tag: 51489

    - 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: Threading Issue Tag: 51445

    - 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. The source is part of the project, or is in an assembly that's part of the solution and referenced as a project assembly. The weird thing is that I can go to definition on most classes, methods, etc. but a few don't work. Is there an object browser cache that I can clear, or can I tell VS.NET to rebuild its object browsing cache? Cheers, MikeS. Tag: Threading Issue Tag: 51427

    - 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). Unless you = choose to limit the format of a non-IP domain string may take (for = example, only allowing alpha characters for the final sub-domain = string), I believe it is impossible to screen out invalid IP addresses. In building this regular expression, I've chosen not to worry about IP = addresses as they will automatically be accommodated. To that end, I'm = stipulating that the DOMAIN of an email address is a collection of one = or more sub-domains (strings of atoms separated by periods). = Sub-domains, as limited above, borrow from the LOCAL-PART and look like = the following: = [^\x00-\x20\<\>\[\]\.\\,;:"@]+(\.[^\x00-\x20\<\>\[\]\.\\,;:"@]+)*= And the full expression is.... = ^(("[^"\x0D\\]+")|([^\x00-\x20\<\>\[\]\\,;:\."@]+(\.[^\x00-\x20\<= \>\[\]\\,;:\."@]+)*))@([^\x00-\x20\<\>\[\]\\,;:\."@]+(\.[^\x00-\x20$= $\<\>\[\]\\,;:\."@]+)*)$ Thoughts?

    - aspnet_wp dies after every page request I have VS.NET 2003 ide (which uses 1.1 framework and Windows 2000 professional). 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: Threading Issue 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: Threading Issue Tag: 51331

    - Projectfiles on networkshare not working Hi, I want my users to be able to save their Visual Studio .NET projects on their homedir instead of the local drive to make backup easier. 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! I set this on the enterprise level, but I've also tried to set it on the machine level. And I've tried resetting all previous policies and then setting the new policy just on it's own. When I try to run a .NET application from the specified share I get the following error message: Unhandled Exception: System.Security.SecurityException: Request for the permissi on of type System.Security.Permissions.EnvironmentPermission, mscorlib, Version= 1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 failed. at System.Security.CodeAccessSecurityEngine.CheckHelper(PermissionSet granted Set, PermissionSet deniedSet, CodeAccessPermission demand, PermissionToken permT oken) at System.Security.CodeAccessSecurityEngine.Check(PermissionToken permToken, CodeAccessPermission demand, StackCrawlMark& stackMark, Int32 checkFrames, Int32 unrestrictedOverride) at System.Security.CodeAccessSecurityEngine.Check(CodeAccessPermission cap, S tackCrawlMark& stackMark) at System.Security.CodeAccessPermission.Demand() at System.Environment.get_MachineName() at NetShareTest.Class1.Main(String[] args) in \\ieshome\home\dd\joakim\visual studio projects\netsharetest\class1.cs:line 17 The state of the failed permission was: <IPermission class="System.Security.Permissions.EnvironmentPermission, mscorlib, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" version="1" Unrestricted="true"/> What confuses me the most is that in the last part of the error message it says "Unrestricted="true", but still I don't have the permissions... It says the same thing when I evaluate any assembly on that share "unrestricted"... but I still get the security exceptions!

    - Application repository Hi all This is a single example scenario, there are many more scenarios which could require the same thing. I have a custom-made ImageList component which holds many images of varying sizes. I then have custom-made controls which use this ImageList to display their own appearances. The images are in an ImageList because many controls would need to share the same images, however, there seems to be no way to achieve the same thing across different forms. It would obviously be better to have a single "repository" in the app which all of these custom controls could refer to in order to avoid having the same images loaded per form. As the controls require the images in order to be displayed properly at design-time, it would also be necessary to specify the image list at design-time so that I can see what I am doing.

    - high processor usage in windows service Hi, I'm hoping someone has ideas... I've written a windows service in VB.net. The basics on starting the service / starting the timer / stopping the service are all based on MSFT documentation. Each section of work inside the timer event is called on it's own thread but the 2nd thread isn't started until the 1st thread has completed or has been aborted. Everything works as expected and I don't get error messages but I have noticed that after about 6 hours of continuous execution, the processor usage starts rising consistently eventually hitting 100% after about 20 hours. I've been through the code 10 times to check that objects are closed & destroyed after usage. Checking in the Windows Performance Monitor confirms that thread counts are normal. Memory also decreases .NET seems to manage this ok. The confusing thing is the processor usage?? Any ideas? Thanks, David Tag: Threading Issue Tag: 51304

    - Passing URL Parameter to an Already Open Smart Client I have many technologies (web pages, Powerbuilder apps, etc.) that I'm trying to "integrate" with some new Windows Forms smart client apps. I think a great way to do this would be passing parameters via the query string as shown in this article: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnforms/html/winforms05152003.asp Also, I am envisioning a user clicking a web link by a HTML table record and the smart client automatically opening a windows showing detailed information about that record. i.e. click on a user's SS# in a web app and their info is available in the smart client. A solution I've been tossing around is this: have all html links go to one place, f.e. driver.exe with parameters for which program to run, what form to auto-navigate to, and what information to show on that form. Something like: http://the.host/driver.exe?prog=UserEditor&Form=Detail&User=101 driver.exe's only job is to start up, see if the program is already running, if it's not start it and pass the parameters, if it is just pass the running copy the parameters. So, driver.exe's lifetime would be very short. Problems I have so far include how to know if a program is running or not, how to get the parameters to the program from driver.exe (remoting?), and if it's actually feasible if I can figure those out. Anybody have any ideas? Other ideas I've thought about are having the driver.exe (or any program) write a file and have the program listen with a file system watcher. Or maybe do the same thing using the clipboard. I've seen some apps that watch the clipboard. That still doesn't answer how to tell if an instance is already running. Thanks for reading my rambling. Any thoughts will be very much appreciated! feech Tag: Threading Issue Tag: 51267

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.
