    - ANN: Report Manager native, full managed version The port of Report Manager engine to C#, mono and dot net is in beta stage, but already working (Linux and Windows). http://reportman.sourceforge.net/doc/dotnetport.html http://reportman.sourceforge.net Basically you can design and tests your reports, using the report designer (Windows and Linux), selecting the dot net provider data connection, then you can execute your reports using the library in your applications. Export to pdf is working so it's useful for web applications, for desktop applications, preview and print is available, note that native Report Manager preview is much faster and flexible, but you can use dot net framework preview if you want. There is a group in yahoo groups (reportman) to discuss, post bugs etc... Thanks Tag: Timer hangs Tag: 114973

    - garbage collection for hastable. Hello all, I am writing a class to cache xml and dataset objects that would be required frequently by my application. I also have a time to check the last access of the obect... If the object is not used for some time I would like to remove it from the cashe to free memmory. I am using hastable to store these objects. What I observe is that even if I remove the object from the hastable the memmory is not freed even if I wait a long time (more than 10 mins) to for the Garbage collection cycle to happen. To make sure there was an issue with the garbage collection I wrote a test application. I declared a class variable for Hashtable in one function I am filling the hastable like below for(int i = 0 ; i < 10000; i++) { HTT.Add(Guid.NewGuid().ToString(),new string('d',40000)); } In another function I am calling HTT.Clear() to delete the items during this time I am observing the memmory useage in the taskmanager. The memmory useage rises as expected in the first function call but does not come down after the second function is called. I waited enough for the GC cycle more thant 10 mins... after the HTT.Clear function call if I call CG.Colloect(); then memmory was coming down. I did not want to do that in my app. please suggest. Thanks in advance, Praveen Tag: Timer hangs Tag: 114968

    - Generate .NET types from C header file? Hi all, The question of reusing C header files in C# comes up frequently and there's really no general solution. I do have a specific problem that I think can be solved and I'd like to get some feedback on. I have a C# app that communicates with an embedded C app via UDP packets. I have to ensure that both sides see the exact same data structure. I know how to do this by defining classes with attributes in C# and defining the appropriate header and compiler switches on the embedded system. I'm wondering if I can have a single source that defines the structure for both systems. Right now I can envision the following solutions: 1) Write a utility that parses the C header and generates the C# class definition. 2) Write a utility that parses some other file format (XML, etc.) and generates both the header and the C# class definition 3) Use C++/CLI to somehow generate a .NET type that gets imported into the C# app. Solutions 1) and 2) are doable but seem kind of tedious and boring. Anyone know if tools like this exist? The C headers have not been written yet and they will be quite simple. No need to parse exotic C constructs. Solution 3) seems a little more interesting but is it doable? Thanks for any comments, Andrew Queisser Tag: Timer hangs Tag: 114920

    - no touch request adds .config to url I have a "no touch" deployment app running successfully on XP. All machines use the 1.1 framework. When a url specifying an exe file is entered on an XP machine, the exe is downloaded by the framework (asp.net on the web server machine) and the exe runs on the "client" machine. The first thing it does is download an xml file. This works OK on the XP client. When the same url is entered on a WIN 2000 machine the exe is downloaded but whe it attempts to download the xml file a ConfigurationException is thrown. The client is trying to download a .config file. The .config is tacked on to the end of the url (no matter how many parameters are on the url) and the request fails. BTW, there is no config file associated with the executable. Why is WIN 2000 different than XP in this case? How can I prevent, or catch, this error? Thx Tag: Timer hangs Tag: 114913

    - database connection loss Hallo! I'm working with C# .NET 2.0, implementing Client/Server Applications which are connecting via Network to SQL-Server or Oracle Databases. To stay independent from the underlaying Database I use System.Data.Common.DBConnection and .DBCommand. How can I keep aware from connection losses (network not availeable, db-server not available...)? Are there any strategies to detect this broken connections, and how can I implement reconnecting to the database? The only solution I figured out, is creating a thread which frequntly performs a SELECT 1 (MSSQL) or SELECT 1 FROM DUAL (Oracle) within a try-catch block. When an exception occurs I have to send my other worker-threads to sleep, till I'm able to reopen the database connection and my Select-Statement works again. Then I have to trigger the other threads to reopen their connections and continue working (every thread gots his own DBConnection). For me this seems a little bit to complicated and insecure. It also could happen that one of the worker threads gots a timeout due locking or delayed server responstime, and will loose his Connection in fact of this exception. Such, or similar problems I can not get handled with my solution. Are there any suggestions, patterns or automathisms with ADO 2.0? with friendly regards Martin Tag: Timer hangs Tag: 114912

    - Recreating an event source in a new event log Hi, I recreating an event message source inside a new log but the messages keeps ending up in the old log?!

I had expected that "MyEntry2" would end up in "myLog2"? What's wrong with this code? regards, martin Tag: Timer hangs Tag: 114904

    - HashTable stores whole object as Key NOT the result of calling GetHashCode on the object when you do myHashTable.Add? Hi All I was testing my understanding of Hashtables and I thought that if I override GetHashCode then i could add an object to hashTable like so: Dim ht As New Hashtable ht.Add(s1, s1) ht.Add(s2, s2) ht.Add(s3, s3) Where s* are instance of a student class that overrides GetHashCode to return the StudentID (code at end of post). I shouldn't add it like: ht.Add(s1.GetHashCode(), s1) as the HashTable calls GetHashCode on the Key for me. This should then store the Hash (The ID returned from GHC) as the Key and the student as the object. However if you loop through the HashTable with: Dim de As DictionaryEntry For Each de In ht Console.WriteLine("Key = {0}, Value = {1}", de.Key, de.Value) Next It shows that the student is stored as both the Key and the Value. Does this mean that you should just add objects to the HashTable like: Dim ht As New Hashtable ht.Add(s1, Nothing) ht.Add(s2, Nothing) ht.Add(s3, Nothing) Seems to me I have misunderstood something here and thw whole point of a HashTable is to use a key to get to a value, was hoping somebody could clear this up for me. Cheers John Student Code Class Student Private _Name As String Private _ID As Integer Private _Age As Integer Public Sub New(ByVal Name As String, ByVal ID As Integer, ByVal age As Integer) _Name = Name _ID = ID _Age = age End Sub Public Overrides Function ToString() As String Return String.Format("{0} is {1} years old and is student no: {2}", _Name, _Age, _ID) End Function Public Overrides Function GetHashCode() As Integer Return _ID End Function End Class Tag: Timer hangs Tag: 114903

    - SmtpClient uses lowercase headers and an odd date format when sending a MailMessage When you send mail using an SmtpClient object (System.Net.Mail.SmtpClient), the headers it adds like "from:", "to:" and "date:" are in lower case. This seems to be a red flag to some spam filters, so it would be good to be able to specify that they be proper-cased, i.e., "From:", "To:" and "Date:". Also the date format used doesn't include the weekday, e.g., "31 Mar 2006 07:25:10 +1200" instead of the more common "Fri, 31 Mar 2006 07:25:10 +1200" which is also a red flag to some spam filters, and so it would be good if it used the latter.

Here is my issue, all of the information I find talks about what you should do for deployment to prod, I've not found very much on how to handle this with a team of developers. Where do we put the assemblies? How do we get each of the dev boxes updated on a daily basis? How do each of the projects get updated to reference the current build of the assembly? How do we deploy current builds, but not screw up anything that may be a work in progress on the developers box? E.G. they are responsible for fixes a bug in a shared assembly.

We could do that already with DateTime's ToLocalTime() method. I have found no combination of values for the new DateTime.Kind flag that gets me back to what worked in 1.1. Why was this changed?

For example, I know in advance thread one will write the first 100MB, thread two 50 next MB, and so on. Can I write from multiple threads ? What objects Have I to use ? One FileStream and seeking as needing ? One FileStream and several StreamWriters ? etc ... Thanks in advance... Steve Tag: Timer hangs Tag: 114847

    - GDI object usage In my application I use a large number of panels and textboxes. If I set the backcolor to each control, the application requires a large number of GDI objects. They are not freed until Dispose() get called. for (int i = 0; i<1000; i++) { t = new TextBox(); // if I comment this statement, the problem does not occur t.BackColor = Color.Red; Controls.Add(t); } How can I limit the GDI object usage while the controls are shown (so I can't dispose them)? Thanks Davide Tag: Timer hangs Tag: 114844

    - How to block loading of BHO and band objects into explorer.exe process Hello! I have developed a managed BHO and band objects which work almost OK. One of two problems I currently face is that they are always loaded into explorer.exe processs when folder browser window is open (they are not loaded at initial explorer.exe startup at the user session start). IObjectWithSite.SetSite implementation is used for checking if process the controls are in is explorer.exe and if yes the COMException with HRESULT E_FAIL is thrown. This prevents controls from being activated but as assemblies are once loaded into process they stay in there until process ends. .NET band object is not a lightweight component and it should be prevented from being loaded as useless memory garbage. My understanding is that explorer loads data into deafult AppDoamin which just stays there until process terminates. I have tried to call AppDomain.Unload(AppDomain.CurrentDomain) but with no success - as expected. This is obviously a bad solution as any other managed BHOs or band objects would be unloaded in case of success as well. Long reasearch pointed me into the direction of unmanaged solution which uses DllMain return value to prevent loading - false is returned when module is loaded into explorer.exe process. Any ideas how can I accomplish selective loading from managed code only? Cheers Tag: Timer hangs Tag: 114841

    - Newbie to .NETdevelopment - where to start? Can anyone point me in the right direction to start .NET The situation is this, I am a experienced J2EE developer who wants to familiarize himself at a development level (& of course improve my CV content). I have used Visual Basic 6 & Visual C++ for many years but not for the last 4! I want to convert some of my J2EE app's to .NET but need obviously to do some good groundwork first in order to see how it's done in the .NET world - where do I start? Any good books, web sites, newsgroups (apologies if posted to the wrong ones!) etc... anyone could recommend would be greatly appreciated! thanks harry Tag: Timer hangs Tag: 114840

    - Component constructor in .NET 2.0 I looked in the documentation for System.ComponentModel.Component's constructor but I only noticed a constructor taking no parameters. My understanding is that there is a second constructor which takes a System.ComponentModel.IContainer interface object. Has this been the case in previous .NET releases and has this changed with .NET 2.0 ? Tag: Timer hangs Tag: 114824

    - Accessing .NET assemblies from classic ASP/VBScript? Hi All, I'm wondering if there is any way to access .NET assemblies from classic ASP/VBScript? We have a legacy app that was written using classic ASP and VBScript, and there's a new facility that one of our developers did in .NET that we'd like to use with our legacy app. Specifically, we have an online signup process that is a multi-page form written using classic ASP. When the user finally completes the signup process, we'd like to package up the form values and send them off to several objects that we have defined in our new .NET DLL. Any thoughts on how to do this? -Josh p.s. please observe Followup-to: microsoft.public.dotnet.general -- thanks! Tag: Timer hangs Tag: 114815

    - Desperate please help with XmlSerializer, IXmlSerializable and XmlSchemaProvider Please, please help me - I am desperate. I have a scenario where I need to send out my object schema in the WSDL. After hunting I found many posts (on MSDN and google) explaining that the way to do this is by using the poorly documented IXmlSerializable interface and the XmlSchemaProvider attribute. I've done this and it works great - my Schema now comes out correctly in the WSDL. Unfortunately, the side effect is that de/serialization no longer works. Why? Because I have to reimiplement the ReadXml() and WriteXml() methods manually. But I don't want to - I like the way the .NET framework serizlizes and deserializes objects. I've seen the code in Reflector - it is HUGE. So how do I pass the power back to .NET to do the de/serialization? Though, as time has gone on I have discovered that no validation occurs and the only way to do this is to use the ReadXml() method to validate the incoming XML. So how do I do this (I guess with an XmlValidatingReader)? So two questions really: 1) How to hand back power to .NET for de/serizliation using the IXmlSerializable interface 2) How to do validation in the ReadXml method and then pass the responsibility back to .NET for deserialization. Please, please, please help me - I am at my whits end. Tag: Timer hangs Tag: 114806

Hello

I have a big problem with a timer (System.Threading.Timer) in a windows
service.

Sometimes the callback-method of the timer seems to hang. It can work more
than one week without problem and suddenly the timer stands still. The timer
check regulary if it's midnight. If not, then it sleeps again for some time.
Suddenly the event to check the time doesn't comes anymore. :-( There is no
more code in the callback-method.

The problem appears on two different Windows 2003 Server with .Net SP1. The
Service runs since about 2 years without any problem on dozen of machines.

Does somebod has had the same problem? Any Idea?

Thanks a lot.
Best regards
Chris
