    - 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: non blocking socket exception Tag: 114920

    - 2.0: Nested configuration data Hi, I'm trying to specify multiple child collection under a ConfigurationSection. I have <asystems name="pippo"> <asystem newName="Production"/> <asystem newName="dev"/> <anotherItem newName="yuk"/> <anotherItem newName="yuk111"/> </asystems> It seems that only one colleciton colud be specified, [ConfigurationProperty("", IsDefaultCollection = true)] public SystemsCollection Systems { get { return (SystemsCollection)base[""]; } } To retrive the simpler config <asystems name="pippo"> <asystem newName="Production"/> <asystem newName="dev"/> </asystems> with a given name like [ConfigurationProperty("asystem", IsDefaultCollection = false)] public SystemsCollection Systems { get { return (SystemsCollection)base["asystem"]; } } did not work.

    - .NET 1.1 created event log has only "Not available" properties We are using VB.NET 2003 Diagnostics.EventLog class on Windows 2000 to create our own custom event log. When using Computer Management and doing properties on the event log it only displays "Not available" for the Size, Created, Modified, and Accessed attributes. The event log is working just not the display of the attributes mentioned above. Does anybody know how to resolve this? -- Thanks, Tim Tag: non blocking socket exception Tag: 114917

    - resource leak issues in win xp sp2 w .net 2.0 Hi, we are running XP SP2 with .net 2.0 framework installed we also installed a .net application that we wrote and run it occasionally without problem. however at some point (even with our application not running) but quite a few other windows open our workstations seem to run out of resources. as in. we cannot open any more windows (be it explorer windows, IE windows or any program for that matter). or sometimes the window will "half" open (the window will come up but say the IE tool button will be missing). now if we close an existing window (IE, explorer window , calc and program) we can then open another program (like a 1:1) correlation. the other thing i noticed when i was in this state and i say tried to run a ping using cygwin i got win32 error 1114 user32 could not be loaded. we have seen this on 4 machines now. any ideas?

    - 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?

    - 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: non blocking socket exception 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 have simplified my code into this tiny snippet: EventLog.CreateEventSource("mySrc", "myLog1"); EventLog eventLog = new EventLog(); eventLog.Source = "mySrc"; eventLog.WriteEntry("MyEntry1"); eventLog = null; if (EventLog.SourceExists("mySrc")) { EventLog.DeleteEventSource("mySrc"); EventLog.CreateEventSource("mySrc", "myLog2"); } eventLog = new EventLog(); eventLog.Source = "mySrc"; eventLog.WriteEntry("MyEntry2"); eventLog = null; The problem is that both "MyEntry1" and "MyEntry2" is written to "myLog1". I had expected that "MyEntry2" would end up in "myLog2"? What's wrong with this code? regards, martin Tag: non blocking socket exception 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: non blocking socket exception Tag: 114903

    - menus Hi all, I am creating an application that has menu options, with a 'Navigation' menu that will re-direct the user to the appropriate form when clicked. I have a Case structure in a class file for the application to access because there are about 12 different forms to choose from. When the appropriate selection is clicked, it will call a method in the aforementioned class file, and pass a global variable to the method. Is the menu index based? I tried to start the Case at: Case = 0 show form a Case = 1 show form b etc. This doesn't work. Any suggestions are appreciated. Thanks! Tag: non blocking socket exception Tag: 114888

    - 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.

    - GAC and development So we've determined that our assemblies will be getting placed in the GAC going forward. I have done a bit of research and determined a process based on that research on how to manage the assemblies for deployment. 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. Anyone currently using the GAC that would like to share how they accomplish this? Thanks Wayne Tag: non blocking socket exception Tag: 114867

    - TimeZone.ToLocalTime changed in 2.0? We have code that used an instance of a timezone (for a timezone other than local), and called ToLocalTime(), passing in a UTC time. In version 1.1, the return value was the time in this time zone. I have found that in 2.0, the return value is the local time for the machine. 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? Was this a bug in 1.1 that was fixed, or is this a new bug in 2.0? Is there a way to do this with DateTime.Kind? Tag: non blocking socket exception Tag: 114866

    - Datagrid Issue - Limit to numeric input? I have a windows form that contains two datagrids (framework 2.0/). I would like to limit two of the columns to numeric entries only. IE If the user types a letter or anything other than 0123456789. then I want to supress the key. I have tried turning on keypreview on the form (I'm using this method to limit entries in other textboxes/controls) but this method does not capture the keys once the datagrid goes into "edit mode". Ideas on how to do this would be great. BTW: When you set the format option of the datgrid column to format for numeric, it still allows the end user to type alpha characters (a-z).

    - about bi-directionnal remoting Hello, Using .Net Remoting, I need to have several clients which use a object on a server. This server should call method on those clients. It's looking like a bi-directionnal communication. But with .Net Remoting I've only found that schema that is not really nice : C1 Activator.GetObject( Server.Object ) C2 Activator.GetObject( Server.Object ) C3 Activator.GetObject( Server.Object ) Server Activator.GetObject( C1.Object ) Server Activator.GetObject( C2.Object ) Server Activator.GetObject( C3.Object ) Is there a good practice to do bi-directionnal communication with .Net Remoting.

    - 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: non blocking socket exception Tag: 114841

    - 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: non blocking socket exception Tag: 114806

    - Why does a private implementation of ICloneable work? Can someone explain why you can implement ICloneable with a private function and it works? e.g. Imports System Public Class BusinessObject Implements ICloneable Private Function privateClone() As Object Implements ICloneable.Clone Dim MyClone As Object = makeClone() Return MyClone End Function End Class Does that fact that the Clone is public on ICloneable mean that the "private" above is ignored when the object is being dealt with as type ICloneable?

    - Resource Leak from XslCompiledTransform Hello there, Are there anybody who is using the XslCompiledTransform that comes with .net framework, which was said to be a replacement of the XslTransform class? I found that the class has some issues when the xsl file contains scripts. The XslCompiledTransform uses the CodeDom to compile the scripts within the xsl file into .net assembly and load them into the current AppDomain. Some temporary files would be generated during the compilation in the temp folder. This behavior leads to two issues. 1, The memory consumption of the current AppDomain, i.e. the working application keeps growing up if we compile more and more xsl files that contain scripts. We have no way to identify the assembly generated from the compiled scripts within the xsl files. Thus we can not release the resources associated with the xsl files. 2, The temporary assembly files can not be removed while the application is executing, since they are engaged by it. The TempFiles.Delete method always fails within the application, consequently. And after running the application for several times, the temp folder might be piled up with the those temporary files. Are there any approaches to solve these problems? -- Best Regards, W. Jordan Tag: non blocking socket exception Tag: 114782

    - ftpwebreques async upload, active transfer problem. Hi, i'm having an inssure implementing and ftpwebrequest upload, using an active transfer problem. I'm trying to catch the "425 Can't open data connection" error returned if an ftp client in active mode tries to connect to an ftp server, and one or the other or both are not configured properly. Here is the code in question: ........ Dim result As IAsyncResult result = request.BeginGetRequestStream(New AsyncCallback(AddressOf EndGetStreamCallback), state) waitObject.WaitOne() .................. Private Sub EndGetStreamCallback(ByVal ar As IAsyncResult) 'User created class to handle async file transfer Dim state As FtpState = CType(ar.AsyncState, FtpState) 'Stream to send to ftp server Dim requestStream As Stream = Nothing Try ' attach the requestStream to the FTPWEBREQUEST requestStream = state.Request.EndGetRequestStream(ar) Catch ex As System.Net.WebException ' handle .................... ........................ A breakpoint has been place at "Dim state As FtpState = CType(ar.AsyncState, FtpState)", the first line in EndGetStreamCallback. When the ftpwebrequest is set to use passive mode, the code breaks at the right line. When the ftpwebrequest is set to use active mode, and the conditions are as stated above for the client and server, the code never gets to the break point and hangs forever at "waitObject.WaitOne()". If i set the ftpwebrequest to use syncronous transfer and the condistions are as stated above for the client and server, the request returns a timeout. So if my request never even gets to the EndGetStreamCallback code, how can i check for connection errors/timeouts? TIA, lushdogg Tag: non blocking socket exception Tag: 114779

    - Weird Problem Reading Char[] data from a BinaryReader I ran into a bizarre problem using the NET Framework 2 which I think is a bug (and at least is a very subtle gotcha if it isn't one). I have to create "c style" structures from binary data in my application. The utility method I wrote to do this creates a BinaryReader from the binary data, and then uses the various read methods (e.g., ReadByte(), ReadBytes(length)) to initialize the structure's fields from the binary data. One of the fields is a fixed length char array (it's always 512 characters long). So my utility method originally did something like this: charArray512 = reader.ReadChars(512); This worked...sometimes. And sometimes it didn't. After digging into it for several hours I noticed that the problem was data-related (i.e., some data caused the problem, some didn't). I finally noticed that whenever the binary stream contained character code 43 (hex 2B) the "code 43" values were being skipped. In other words, the following binary stream (hex): F0 9B 74 81 2B 12 would be read as: F0 9B 74 81 12. The 2B code was simply skipped. I have no idea why ReadChars() ignores certain character codes (at least including 2B). My workaround is to use ReadBytes() instead of ReadChars(), and then convert each byte to a char using Convert.ToChar(). This is slower, but doesn't drop the 2B codes. BTW, the encoding on the binary stream (and the reader) is set to ASCII. Can someone explain to me why the 2B codes are being dropped? Is this a bug in ReadChars()? - Mark Tag: non blocking socket exception Tag: 114774

    - VS2005 Embedded Crystal Reports Deployment problem. Hi, WinApp project migrated from VS2003. ( Where reports used to deploy OK) The help indicates that you just need to make a new setup project with no special consideration for Crystal Reports. (Previously a series of merge modules had to be added) However when I attempt to open a report on the target machine I get a runtime error saying that the Crystal engine assembly is missing ( 10.2.3600).

the exact message I receive is
A Non-blocking socket operation could not be completed immediately
I am using remoting over a tcp channel, this error does not occur on all
machines just a select few.

Hi Ricky,

Thanks for posting!

For the current issue, my understanding is that the "A Non-blocking socket
operation could not be completed immediately" error is encountered when you
using the .NET Remoting application. If I have misunderstood anything,
please let me know.

As far as I know, the error belongs to WinSock error. Actually, the Winsock
error relates to communication errors encountered with Ethernet Devices or
the setting of these devices. It is good way to contact your MIS/IT
department for resolving these errors. For example, some specific firewall
issues or networking issues will lead to the error. However, the error
isn't caused by the .NET Remoting application itself.

I appreciate your understanding!

Regards,

Yuan Ren
