    - DateTime.ParseExact mit Wildcards Hallo, gibt es mit DateTime.ParseExact eine Möglichkeit Wildcards zu verwenden? Beispiel: "20071007abcd123100" soll geparst werden, wobei "abcd" beliebige andere 4 Zeichen seien können. Ich denke also an so etwas wie: DateTime.ParseExact("20071007abcd123100", "yyyyMMdd????HHmmss", null); Hat da jemand eine Idee? danke & ciao Torsten Tag: XML Serialization at Design Time Tag: 131758

    - 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?

    - Question about return 0 in Socket::EndSend in C# I have written a program that is using Async Socket, And the program will send a lot of packet to the socket, and i used BeginSend and EndSend for sending the data. But the werid thing is that, sometime, the EndSend return 0, so it implies that 0 byte of data have been sent, so the my program will try to do the BeginSend again and try to send the data again, but the result is that the other side will receive 2 same packets. So what is wrong with it? Thanks Tag: XML Serialization at Design Time Tag: 131750

    - 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: XML Serialization at Design Time 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: XML Serialization at Design Time Tag: 131731

    - .NET Framework 2.0 for Windows XP SP1 I noticed on the Microsoft .NET Framework 2.0 download page that Windows XP SP1 is not a supported environment. Does this mean that the 2.0 Framework will not work on an XP system with only SP1 installed?

    - Should be simple C++ managed header include question I have a split container on my form, from within one of them I wish to reach the main from of the app. I'm having problems with the headers and namespaces. I want something like this: //within right pane form ABCForm^ abcForm = (ABCForm^)Application::OpenForms["ABCForm"]; abcForm->ExecutePublicFunction(); If I include the main form header I get: 'ABCForm' : undeclared identifier 'abcForm' : undeclared identifier syntax error: ')' and many more.... 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. So what's the proper way to reference the other form and handle the includes and namespace from another form? This should be simple I know...

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: XML Serialization at Design Time Tag: 131712

If it does, then i would like to compare the 2 objects using the operators. Is this possible to do? In general, i am solving this problem, "If 2 objects can be compared, return their comparison value". I can check if they implement IComparer/IComparable but i don't know how to proceed after that.

    - 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: XML Serialization at Design Time 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?

    - 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: XML Serialization at Design Time Tag: 131676

    - 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.

    - Windowsservice an Mapped Drive My service runs under a Domain Account mydomain\myuser. If I log into my system under this mydomain\myuser I have acces to a mapped drive x:\ which is mapped to \\mydomain\mymachine\myfolder. The service can acces \\mydomain\mymachine\myfolder but not x:\. A winform application which I start when logged in as mydomain\myuser has access to x. Any ideas?

I subscibe to a european streaming TV website - while it worked flawlessly for months, all of a sudden this message began to pop up! Login still works, but the player freezes at the connecting to media stage, while waiting for the network password. All other internet functions work normally, and I don't have a network.

    - Copy DataTable Rows Fast? .NET Framework 2.0 I have a custom class inherits from DataTable. 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. Now I need to just get the data columns and rows from the TableAdapter into my lightweight class. I think I want to do something like RemoteTA.Call( param1 ).Rows.CopyTo My DataTable does not have any columns or rows to start. Thanks. Tag: XML Serialization at Design Time Tag: 131656

    - .NET 3.0 and IIS 6.0 on Windows Server 2003 SP2 Sorry if this is the wrong place to post... did a quick search and couldn't find a better location I installed .NET 3.0 on my Windows Server 2003 SP2 (x64) running IIS 6.0. Now I get a simple "Service Unavalable". I saw a post that said to use IIS 5.0 isolation mode. This basically prevented my default web site from starting up. Does anyone know if this is even possible? Thanks for your help! Tag: XML Serialization at Design Time Tag: 131652

    - .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?

    - Why is ref needed here? When I pass my List<> without the ref keyword persons2 is empty (Count = 0 below). If I add the ref keyword to the caller and the function then Count is correct. I don't understand because if I call DeSerialize(persons2, path) don't I by default send a reference not the actual List<Person> since List is an object? Thank you! //The below works since I have the ref keyword... class Program { private const string path = @"c:\temp\Serialization.xml"; static void Main(string[] args) { List<Person> persons = new List<Person>(); persons.Add(new Person("Person", "One")); persons.Add(new Person("Person", "Two")); Serialize(persons, path); List<Person> persons2 = new List<Person>(); DeSerialize(ref persons2, path); Console.WriteLine(persons2.Count.ToString()); Console.ReadLine(); } static void DeSerialize(ref List<Person> o, string path) { XmlSerializer serializer = new XmlSerializer(typeof(List<Person>)); StreamReader xmltext = new StreamReader(path, true); o = (List<Person>)serializer.Deserialize(xmltext); xmltext.Close(); } } Tag: XML Serialization at Design Time Tag: 131645

    - Font problem in reports when the font doesn't exist We have created many reports using the Arial Unicode MS font with Crystal Reports. All was good until we tried them on systems that don't have that font installed. The reports are showed, somehow, but an error message will pop up for every piece of text using that font -it says the font is not installed or something like that. Here's an example, if the report is showing 10 fields per record, and there are 3000 records, then the error message will pop up 30000 times. Not nice. It was not a problem when we were using VS2003, but it became a problem when we converted the project to VS2005. Maybe it's a conversion issue? We are not sure how to deal with this. Should we embed the fonts in case they are not installed? Should we use another set of standard fonts? Thanks! Paul Tag: XML Serialization at Design Time Tag: 131644

    - why no dead lock for this one? Hello, I did this as a test code: public class test{ .... .... public void test(int i) { lock(this) { if (i>10) { i--; test(i); } } } } I thought that when I run test(11), it should give me a deadlock as first it asks to lock the instance of the class, then as i is bigger than 10, it will go deeper and try to lock the instance of the class again, as it has been locked, then it should just wait there for ever. But it went through without any deadlock, can someone tell me what is wrong with my understanding? Many Thanks Jerry Tag: XML Serialization at Design Time Tag: 131642

    - Thread Synchronization with ManualResetEvent Hi Everybody, I have some understanding problems, about (thread) synchronization. Hopefully somebody can explain it to me. I have the following two processes that use the same piece of hardware. However, they are not allowed to use it at the same time: Process 1: System.Threading.Thread Process 2: System.Timers.Timer elapsed event I have taken two approaches to synchronize the access of these two processes to the piece of hardware: 1. With Monitor.Enter(this) and Monitor.Exit(this) in a try-finally block of the hardware code 2. With ManualResetEvent WaitOne(), Reset() and Set() also in a try- finally block. Both these methods could not prevent the hardware from getting called twice. My own theories why this doesn't work are: 1. Monitor synchronizes different Threads, but an elapsed event runs on the same thread? 2. Two threads can both call WaitOne() at the same time, before one of them had the chance to call Reset(). They will both then pass WaitOne(), because the ManualResetEvent is for both still in the signaled state. ' I have written some test code to test situation 2 and indeed there seems to be a possibility of no synchronization. I have posted the code below. Can anybody explain me why this happens, and how I can get a synchronization for this? Kind regards, Gerben Heinen ### CODE ### using System; using System.Threading; namespace ConsoleApplication3 { /// <summary> /// Summary description for Class1. /// </summary> class Class1 { public Class1(){} /// <summary> /// The main entry point for the application. /// </summary> [STAThread] static void Main(string[] args) { Class1 c = new Class1(); c.Start(); } private Thread thread1,thread2,thread3; private ManualResetEvent mre = new ManualResetEvent(true); private volatile int cntr = 0; private Random random = new Random(); public void Start() { thread1 = new Thread(new ThreadStart(worker1)); thread2 = new Thread(new ThreadStart(worker2)); thread3 = new Thread(new ThreadStart(worker3)); thread1.Start(); thread2.Start(); thread3.Start(); } private void worker1() { while(true) { try { Thread.Sleep(random.Next(100,1000)); mre.WaitOne(); mre.Reset(); // Console.WriteLine("worker1 started"); cntr++; Thread.Sleep(random.Next(100,1000)); cntr--; } finally { mre.Set(); } } } private void worker2() { while(true) { try { Thread.Sleep(random.Next(100,1000)); mre.WaitOne(); mre.Reset(); // Console.WriteLine("worker2 started"); cntr++; Thread.Sleep(random.Next(100,1000)); cntr--; } finally { mre.Set(); } } } private void worker3() { while(true) { if(cntr==2) System.Console.WriteLine("Cntr equals 2"); Thread.Sleep(10); } } } } ####### Tag: XML Serialization at Design Time Tag: 131629
