    - MVC Framework Hello all, I've been searching for a video I found a while back which showed a MVC style framework which was used to seperate the business logic from the UI. This made it possible to use the exact same logic in both asp.net and WPF. I had thought that this was a video showing Microsoft developers showing off the technology but now I'm not sure as I can't find the video again. I would really like to know if anyone knows what this framework was or where this video is as I have spent many hours now trying to find it again. The only details of it that I can remember is that it was an MVC style framework and that the example in the video was using asp.net. I also remember there being View and Controller interfaces used along with it. Tag: Help IIS Identity Crisis Tag: 131806

    - Thread safety of events Hi, I have an object O1 that executes code in thread T1. O1 raises events. There is an object O2 that runs in thread T2. O2 catches O1's events. Question: What happens if O2 is detaching the event handler at the same time as O1 is raising the event? Do I have to handle this special situation explicitly? Honestly I haven't read/heard that anybody ever cared about this. It would be pretty much work to do because every event handling object would have to prevent the event raiser from raising the event while detaching it's own handlers. Not a good OO way also. I know the "instance members are not thread safe" part of the Delegate/Multicastdelegate documentation, but I also think that Events are a basic element in the runtime's infrastructure, so maybe I don't have to handle the situation explicitly?

    - Maintain list of attached event handlers (.Net 1.1) Hi, here's the short version: How can I remember which event handlers did I attach to which events? Background: - I have an object tree. There is one root object, containing sub objects, containing sub objects, and so on. All the objects in the tree can raise events. - In a Form's Load event, I recursively process the object tree and attach event handlers to all the events of the objects in the tree. - Whenever an event fires, I detach the event handler. (because it won't fire twice) - When the Form closes, maybe not all events have been fired. Therefore, there are still event handlers attached to these events. My goal is: I must detach the remaining event handlers when closing the Form. Question: How do I know which event handlers are still attached? I thought I simply could maintain a list of attached event handlers. Whenever an event fires, I detach the event handler and remove the corresponding entry from the list. So, if the Form closes, I only have to process the list in order to detach the remaining handlers. But, /what/ do I have to store in the list? I didn't find a way without using Reflection. Thanks for reading! Armin Tag: Help IIS Identity Crisis Tag: 131789

    - Running out of Sockets I am working on a .Net Web Service which will be used by thousands of users at a time. It does lot of file operations (Creating, deleting, enumerating, reading attributes etc) and Ldap queries to AD using .Net APIs. Under stress test, service machine runs out of Sockets and we start seeing weird errors. I created MaxUserPort entry in registry on service machine toa llow 65,500 max no. of sockets to be created. It runs fine now. It could be a problem later during more stress in production. Is there a way in .Net to minimize socket usage during file and ldap AD operations? Is there a way i can force the machine to recycle the sockets so it never runs out of socket. Thanks, Salim Ansari Tag: Help IIS Identity Crisis Tag: 131781

    - RS232: How to set rts=tg and xon=off I'm developing an interface application for existing multiport direct connect modem ports (RS232) that require setting rts=tg (toggle) while keeping xon=off. The environment is VB in VS2005. I would like to use the System.IO.Ports.SerialPort class but the only handshaking I see that comes close is Handshake.RequestToSendXOnXOff (3) and that uses xon=on. The RtsEnable is a boolean that represents on|off. Rts is actually 2 bits and can be set to [on|off|hs|tg]. Am I totally missing something or do I have to fall back to the Win32 API?

    - Temporary Files And Permissions Hello, I have been struggling quite a bit with a problem that cannot possibly be this difficult to get past. The full scenario, is that I want to get a file from our Visual SourceSafe database, run a parser on it (translates an SQL dialect) and check it into another location. Now the SourceSafe and translation bit of all this works like a charm, but handling the temp files don't. The basic structure (first cut) looks like this: private void button3_Click(object sender, EventArgs e) { IVSSItem itemSybase = dataBase.get_VSSItem(comboSybasePath.Text, false); IVSSItem itemSQL = dataBase.get_VSSItem(comboSQLPath.Text, false); string pathSybase = Path.GetTempFileName(); string pathSQL = Path.GetTempFileName(); FileInfo fileSybase = new FileInfo(pathSybase); FileInfo fileSQL = new FileInfo(pathSQL); try { itemSybase.Get(ref pathSybase, (int)(VSSFlags.VSSFLAG_REPREPLACE | VSSFlags.VSSFLAG_FORCEDIRYES)); itemSQL.Checkout("Automatic conversion from Sybase", pathSQL, (int)(VSSFlags.VSSFLAG_REPREPLACE | VSSFlags.VSSFLAG_FORCEDIRYES)); try { ConvertStoredProc(fileSybase, fileSQL); itemSQL.Checkin("Automatic conversion from Sybase", pathSQL, 0); } catch { itemSQL.UndoCheckout(pathSQL, 0); throw; } } finally { fileSybase.Delete(); fileSQL.Delete(); } } Essentially, I get the temp file names with Path.GetTempFileName() and let SourceSafe overwrite the first file. I then use FileInfo objects to process the source text, write the destination file and finally delete both files once the destination file has been checked into SourceSafe. What perplexes me no end, is the fact that I can create the temporary files without a hitch, but deleting them again causes a SecurityException to be thrown. Why can I not delete a file that I was able to create? I then tried to specify FileIOPermission on my application, but the same is then used on the imported assembly for SourceSafe. And since I don't actually want to access anything other than the temp folder, I really want to specify Path.GetTempPath() as the path to get permission to - where do I do that? Finally, I thought I would use isolated storage, but again ran into trouble. Unless I missed it somehow, you cannot actually get the name of the file path you are working with - which means that I cannot specify that path for SourceSafe to use! Right now, it almost seems like the most reliable way of doing this will be to simply leave the temp files, but that is messy. Any ideas? Cobus Kruger Tag: Help IIS Identity Crisis Tag: 131756

    - Can ternary conditional expressions be represented in the CodeDOM? ... I know I could use a CodeSnippetExpression to do it, but that would somewhat hardcode the resulting tree. I was looking for something like: CodeTernaryExpression( CodeExpression test, CodeExpression trueExpression, CodeExpression falseExpression); Which would, of course, get turned into the corresponding: (test ? trueExpression : falseExpression) expression in C#, C++, or even J# (I believe). I guess it's only VB.NET that doesn't have a ternary expression but I don't know for sure. I know, I know, for generated code there's no real reason to use a ternary expression, but coding habits are hard to break, even when writing meta-code :-) Regards, -- TB Tag: Help IIS Identity Crisis Tag: 131740

    - Problem with SslStream when using Windows Vista Hi. When my client program runs under XP and calls a server (solaris in this case) via an SslStream all is well. The client may make multiple calls and multiple authentication calls and be fine. I expressly "clean up" everything streamwise and socketwise and all is well. Running the client under Vista, when the second authentication call is made it returns the following SSPI error: "A call to the SSPI failed, see inner exception" which reads "the Local Security Authority cannot be contacted" Well that was pretty mystifying so I looked at what was going on with ethereal. Apparently, on the second authentication go-round Vista asks the server to re-use a session Id. The server responds and then Vista rejects a re-used session Id (even though it asked to do that). What I have found out is that the .net framework caches SslStream sessions automatically, I have not found any way to turn this off for Vista - any ideas on how to do this or to get Vista to use the cached SessionId which it requested? Here is a link to a sample that seemingly generates the same flaw that I have described. http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1222194&SiteID=1 Thanks Dave Tag: Help IIS Identity Crisis Tag: 131731

The two forms are of the same namespace. if within the namespace I do this: namespace ABC{ ref class VPEForm; public ref class OtherForm : public Form { the line: ABCForm^ abcForm = (ABCForm^)Application::OpenForms["ABCForm"]; will compile without complaint. But then the line: abcForm->ExecutePublicFunction(); I get: use of undefined type : 'ABC:ABCForm' Like it sees the 'ref class VPEForm' as the complete definition of the class.

If I send for example (loop based) 300 emails the following happens. The first 100 emails are sent. Now I get the exception. 'Could not access CDO.Message object'. This is not a problem of the email server. Because: If I wait for example 1 hour, I can again send 100 or so emails then the error. Or I can boot the computer, then I can send 100 or so emails and then the error again. Seems that there is something locked after a number of emails on the computer. Thank you for any help.

    - WPF Question. I'm not sure which is the right forum to post this question - so this is as general as can be. There question is about treeview in WPF: I'm trying to implement drag and drop in TreeViews, poking all sorts of options for their display. The code I'm based upon is Josh Smith's ListViewDragDropManager, and just converted it to manage treeviews, with almost all of the same code. The logics are all exactly the same, and the display is also from another project I saw recently. What I came across is just very weird: when I expand a TreeViewItem, then collapse it, the TreeViewItem thinks it's still expanded. all of the DragOver events come from the incorrect treeviewitem, which is ofcourse very bad. The best way to understand what I'm saying is to look at this test project, and do the following: 1. drag the first item around a little, see that you get all the normal behavior. 2. expand the first item. 3. collapse the first item. 4. try the drag operations again. notice how when you pass over items from the second row, the mouse thinks it's over the first row treeviewitem. solution is here(zip) : http://www22.brinkster.com/betzera/ohev/dev301/treeview%20dragger.zip 10x, Dani Tag: Help IIS Identity Crisis Tag: 131712

    - Machine locks up running app off network I have a .NET application that is run off of a shared network drive. About 5 users (out of 100) periodically have their entire machines deadlock when they try to run the application. I was able to reproduce the issue a couple times on one of the user's machines. One time I had the Task Manager open when I launched the app and the Task Manager also stopped responding (ctrl-alt-delete did nothing either) I tried re-installing the .NET Framework, but I was still able to get the machine to lock up when I launched the application. I also tried running the application locally and was not able to get the machine to lock up though this is not an ideal solution. The reason we run it from the shared drive is so that we do not have to distribute updates to every user. I did some research and read about how deadlocks can occur in mixed- mode dlls if you try to run managed code in the DllMain of the unmanged code, but we do not have any unmanaged code in our app. Even if we did, that would only deadlock the process it is running in and not the whole machine, correct? It seems like the machine is deadlocking when the CLR is loading the application but before it starts executing b/c the splash screen for the app isn't shown before the machine stops responding. Does anyone have any ideas on what could be causing this behavior? Tag: Help IIS Identity Crisis Tag: 131684

    - BUG? XmlSerializer serializes List<> { get; } property twice [LONG Framework: .NET 2.0 Description: The code (see below) is an extract of a larger application. The main points are: 1. There ist an abstract base class 2. This class has a virtual List<> { get; } property 3. The property is decorated with XmlArrayItem attributes 4. A class derives from the base class 5. This class overrides the List<> property 6. There is an identical (for the sample code, not in real life) other class deriving from the abstract base class 7. The XmlSerializer gets both derived types as extraTypes in the constructor One of the derived classes serializes correctly the other gets the List<> property serialized twice. Actually this behaviour is much more strange: 1. If another (equal) derived class is added this shows that only the FIRST extraTypes[] class is serialized correctly, all others got duplicate members 2. When the List<> is replaced by an Array [] { get; set; } there seems to be no problem Is this a known bug and especially is there a known work-around?

    - ClickOnce Problem with .NET Framework Installation I have a C# application that I am distributing and updating via ClickOnce. I have the .NET Framework 2.0 as a prerequisite. On some computers, but not all, when the app is installed for the first time, and the Framework needs to be installed, the Framework installation piece will hang the user's computer. A reboot is normally required. What's odd about this is that the Framework has been installed successfully but the computer hangs up. Has anyone encountered this? Thanks very much.

    - tcpclient in .net 2.0 Maybe someone has come across this situation and has a way to handle it. If I have a tcpClient object and do a GetStream.Read on it after setting a ReceiveTimeout, I'm getting different behavior in .Net 2.0 than in 1.0 when the method returns 0 bytes (which signifies a timeout). In both cases I get a System.IO.IOException , but in the 2.0 framework the socket also disconnects when this occurs (in 1.0 it did not disconnect). They have made some improvements in the tcpClient class, such as exposing the underlying socket, so I'd prefer to keep using tcpClients. Any idea how I can prevent this disconnect? Right now I'm checking DataAvailable and using Thread.Sleep as a workaround, but I'd prefer to do a blocking read call. Thanks, Keith Tag: Help IIS Identity Crisis Tag: 131676

    - ClickOnce Content Files I have a solution with multiple projects. One project is a windows forms project. I have report files (.rdlc) in a separate project that are built as "Content" with the "Copy Always" option. When I build the solution, these files are copied to the bin\Release directory, as they should be. However, when I publish the Windows Forms project, these content files are not copied. How can I make it so that these content files from the one project are published along with the windows forms project. They are not listed in the "Applications Files" section of the publish settings. Thank you... Tag: Help IIS Identity Crisis Tag: 131675

    - Migrate large .NET 1.1 app to 2.0 or 3.0 (ie, when will SP's ship? We're trying to decide whether to migrate a large .NET 1.1 (ELB 1.1) app to .NET 2.0 or 3.0 (with ELB 3.1, probably)... within the next two months. I've seen discussions that hint that the (long overdue) SP1 for .NET 2.0 will ship around the time that Orcas ships (early '08?). We could probably tolerate that if we migrate the app to 2.0 now. On the other hand, if we migrate to 3.0 now, when will SP1 for .NET 3.0 ship? Since 3.0 is purportedly an extension to 2.0, and isn't supposed to have changed the "core" of 2.0, would we be able to apply 2.0 SP1 to 3.0? But if the 2.0 SP1 doesn't also apply to 3.0, and the 3.0 SP1 will be even later (1.5+ years, as the 2.0 SP has proven to be), then there's no way we could consider migrating to 3.0 now...

    - Control.Invoke() blocking forever if form closed whilst background task running In part of the system I am working on I have a background task (started with a call to BeginInvoke() on a delegate), which at some point needs to read a property from one of the controls on a form. Normally this all works great. The problem I am having is if the user closes the form whilst the background task is running. Execution blocks indefinitely on the call to Control.Invoke() and the method I supply to it never begins. The application's message queue doesn't seem busy and the UI is still responsive other than I have this thread sitting in the background, stuck on this call. I am calling Invoke() on a custom UserControl that has not yet been disposed. The stack trace to where it is blocking inside Invoke() shows up as the following... [In a sleep, wait, or join] mscorlib.dll!System.Threading.WaitHandle.WaitOne(long timeout, bool exitContext) + 0x2e bytes mscorlib.dll!System.Threading.WaitHandle.WaitOne(int millisecondsTimeout, bool exitContext) + 0x23 bytes System.Windows.Forms.dll!System.Windows.Forms.Control.WaitForWaitHandle(System.Threading.WaitHandle waitHandle = {System.Threading.ManualResetEvent}) + 0xa1 bytes System.Windows.Forms.dll!System.Windows.Forms.Control.MarshaledInvoke(System.Windows.Forms.Control caller, System.Delegate method, object[] args, bool synchronous) + 0x36d bytes System.Windows.Forms.dll!System.Windows.Forms.Control.Invoke(System.Delegate method, object[] args) + 0x48 bytes System.Windows.Forms.dll!System.Windows.Forms.Control.Invoke(System.Delegate method) + 0x7 bytes I can get around the problem by replacing the Invoke() call with a BeginInvoke() and therefore being able to specify a timeout, but I'm curious as to why it's happening in the first place.

It has a method to "get remote stuff" where it makes a web service call to a .NET 2.0 web service that executes a TableAdapter.

    - .NET BroadcastEventWindow 2.0 Problem on log out I am having problems with our client based part of our .net 2.0 distributed application. We find that when a user logs out of the system they are having problems. A window appears all the time when they log out, it says .NET-BroadcastEventWindow 2.0.0. I have googled this and can find no really good explanation for what it is or what would cause it. I don't know whether this is a problem with .NET 2.0 or our client apps. I was wondering if it was to do with threading or memory problems of some kind. When our client tools finish their work they basically go to sleep, thread.sleep for a specified time period. Would this cause the window to appear, that they thread is not being dealt with properly. I tried using SessionEndingEventArgs to cancel everything but that has no effect. Anyone any ideas? Thanks Eamonn Tag: Help IIS Identity Crisis Tag: 131649

I have a web application (.Net 2.0, IIS 6 Windows 2003) that uses an
unprivileged user as the identity for the application pool. IIS
requires the user have the "log on as a batch job" right. My web
application calls a WCF MSMQ service and uses a certificate for
authentication (not encryption as this is a workgroup server).
Unfortunately, the application cannot find the certificate and throws
an exception. I believe this to be because IIS is doing a "log on as a
batch job" and the user's certificate store is not available. As soon
as I open a command shell "runas" the user, the user's profile is
loaded, the certificate store is available and I can successfully send
an authenticated request to my WCF service.

I'm happy I finally managed to establish why this was working
sporadically:
Step 1 - send request to web service; fails because can't find
certificate
Step 2 - open MMC "runas" IIS application pool identity to check
certificate exists
Step 3 - yep, it's there alright
Step 4 - oh, now my application works, WTF

Is there some way to require IIS to load the application pool identity
profile?
