    - DataTable.Select with condition with Timespan values Hi to All, i'm using C# in .NET 2.0 and i have a DataTable A with a column of type TimeSpan used to store HOUR info. I'm trying to filter my DataTable A selecting only rows that have the column HOUR > .... if i try to Call A.Select( " HOUR > '10:30:00' " ) i receive an error ( cannot compare TimeSpan with String ...) if i try to call A.Select ( " HOUR > 10:30:00 " ) i receive an error ( invalid token : ) if i try to call A.Select ( " HOUR > Convert('10:30:00',System.TimeSpan) " ) i receive an error ( string '10:00:00' is not a valid TimeSpan ) if i try to call A.Select ( " HOUR > #10:30:00#" ) i receive an error ( Cannot compare TimeSpan with Date ) ... ... i think that i missed only the right way to write my filter. Can someone help me? Thank you in advance. Regards, Massimo Tag: Wrapper assembly - VS2005! Tag: 131719

    - 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... Thanks, Steven Tag: Wrapper assembly - VS2005!

    - MailMessage-Object error - net 1.1 , VS 2003 Hello, I have a simple program which sends emails. The main function is: private bool InitAndSendEmail(string mailTo, string subject, string txt, string mailFrom) { MailMessage myMail = new MailMessage(); try { myMail.From = mailFrom; myMail.To = mailTo; myMail.Subject = subject; myMail.Body = txt; string smtpServer = "mail.kybtec.de"; string userName = myMail.From; string password = "12345678"; int cdoBasic = 1; int cdoSendUsingPort = 2; myMail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpserver", smtpServer); myMail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpserverport", 25) ; myMail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusing", cdoSendUsingPort) ; myMail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate", cdoBasic); myMail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername", userName); myMail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword", password); myMail.BodyEncoding = Encoding.UTF8; myMail.BodyFormat = MailFormat.Html; SmtpMail.SmtpServer = smtpServer; SmtpMail.Send(myMail); myMail = null; return true; } catch(Exception ex) { MessageBox.Show(ex.Message); return false; } } This works fine if I only send for example 10 emails. 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: Wrapper assembly - VS2005!

    - V C++ .NET version 2003.Compiler problem. V C++ .NET version 2003.Compiler problem. My compiler is acting up. When I have building error, the left margin pointer will point to the wrong line. Sometimes, the deferent between the line that has the error and the line it pointed to can be more than twenty lines. Sometimes, It will give error message for something that I commented (//). As soon as I delete the commented line, the building error will disappear . I uninstalled the compiler and install it again: I still have the same problem. I used to have version 2005, I Uninstalled it and I still have the same problem. I recently installed the service pack recommended for this compiler. I wonder if any body has experienced something like this, before. Or anybody has an idea; what is the reason for that and how can I fix this problem; I would appreciate it.

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: Wrapper assembly - VS2005! 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: Wrapper assembly - VS2005! 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.

    - .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?

    - 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: Wrapper assembly - VS2005! Tag: 131644

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: Wrapper assembly - VS2005!

    - Performance Counter Next Value always returns zero (MS Exchange counter) Hi, I've got an application that users the PerformanceCounter class to retrieve perfmon values. Generally this works fine, but it seems the following counter always returns 0 for the nextvalue: MSExchange Intelligent Message Filter % UCE out of Total Messages Scanned _Total There is a raw value, and if I manually divide that by the value returned from the Total Messages Scanned, it shows the same % as in perfmon. .NET always returns 0 however. I am aware of an MS bug in article 324548 showing that disk values return 0, but is this the same problem with just different counters? Regards Bobby Tag: Wrapper assembly - VS2005! Tag: 131620

    - question about localization and multi threading Hello, Suppose I have a windows form running in culture A, then the form creates a new thread (call a method foo for example) and makes it using culture B. When method foo is running in the new thread, it may try to change a label in the form. So code is like: foo() { string message = resMan.GetString("strLabel"); if (label2.InvokeRequired) label2.Invoke(new MethodInvoker(foo)); else label2.Text = message; } The problem is that it will never show the label as culture B as foo finally goes to the thread the windows form is running (culture A). So what is the best way to handle it? The real code was written without consideration of localizaton but now requirement is added to support multi cultures.

    - System.Diagnostics.StackTrace future ? The constructor new System.Diagnostics.StackTrace(System.Threading.Thread targetThread, bool getSourceInformation) *requires* that the target thread be suspended. But System.Threading.Thread.Suspend (and .Resume) are currently labelled Obsolete and the documentation states that they are scheduled to be removed in a future version. What is planned to avoid the upcoming uselessness of this StackTrace ctor? Our suggestion would be another signature for the StackTrace constructor which takes a boolean flag indicating that you want the stack trace even if the thread is not suspended (implemented however they want, maybe by suspending the thread internally). All you are assured is that the returned stack trace was a true stack trace for the target thread *sometime* during the StackTrace ctor call. We are using this feature to perform statistical execution profiling of a thread from within the application itself (using another thread of course). Tag: Wrapper assembly - VS2005! Tag: 131603

I have a strong name for the project set in the project. What do I have to do to allow this application to be called from a file server instead of the local drive.

    - private fields of component show up in debugger Should private fields of a .NET component show up when debugging the container application? Example, I have a field defined as [NonSerialized] private bool disposed = false; When I set a breakpoint in my container app and look at the component's props/fields list in the debugger, the field 'disposed' is listed. If I change it to private, it does not show up. Obviously a simple change, but I'm not clear on the rules. Tag: Wrapper assembly - VS2005! Tag: 131560

Hi,

I am trying to use a managed dll (does not have a strong name) in my app/dll
which is signed. I get an error "Referenced assembly does not have a strong
name".

i tried using the tlbimp.exe to create a wrapper dll which has a strong name
but get the error "TlbImp : error TI0000 : The input file 'xyz.dll' is not a
valid type library.".

Any ideas on how i can do this? is there an equivalent of the project
property "Wrapper Assembly Key file in VS.Net" which i can use in VS2005.

Thanks,

- SA
